The Gemedy SKEIN tool visualizes any uncovered networks of influence and provides recommendations for either leveraging or counteracting those networks. Late stage clinical failures have forced the field to reevaluate the tools and hypotheses which have been used to design and develop drugs for central nervous system CNS disorders for the past 25 years. A number of key challenges have been identified: Complex CNS diseases, which are caused by the interplay between many genes and pathways, are unlikely to be effectively treated using drugs which target a single protein.
The battery of standardized laboratory rodent models of behavior is far from optimal in predicting human clinical outcomes. Clinical trials of CNS drugs are hampered by the lack of objective measures of disease state and drug effects. At Galenea, we believe that each of these significant challenges can be addressed by a focus on synaptic transmission — the means by which signals are transmitted from neuron to neuron and across dense networks in the brain.
Dysfunctions in synaptic transmission are key elements in Alzheimer’s disease AD , Parkinson’s disease, Huntington’s disease, epilepsy, bipolar depression, schizophrenia, autism spectrum disorders, and traumatic brain injury. And in neurodegenerative disorders such as AD, changes at the synapse appear very early in the disease.

Short linear shadows connecting pulmonary segmental arteries to oblique fissures in volumetric thin-section CT images: comparing CT, micro-CT and histopathology.
To retrospectively evaluate short linear shadows connecting pulmonary segmental arteries to oblique fissures in thin-section CT images and determine their anatomical basis. CT scanning was performed on patients and 11 lung specimens with no lung diseases around the oblique fissures or hilar. Two radiologists evaluated the imaging.
The parameters included length, thickness of short linear shadows, pulmonary segmental artery variations, and traction interlobar fissures, etc. The short linear shadows were not related to sex, age, or smoking history. The lengths of the short linear shadows were generally within 10 mm.
The thicknesses of the short linear shadows ranged from 1 to 2 mm. Of the patients, In three-dimensional images, the short linear shadows appeared as arc planes, with one side edge connected to the oblique fissure, one side edge connected to a pulmonary segmental artery.

Left ventricle segmentation of a human heart in magnetic resonance images MRI is a crucial step in both cardiac diseases diagnostics and heart internal structure reconstruction. It allows estimating such important parameters as ejection faction, left ventricle myocardium mass, stroke volume, etc.
In addition, left ventricle segmentation helps to construct the personalized heart computational models in order to conduct the numerical simulations.
At present, the fully automated cardiac segmentation methods still do not meet the accuracy requirements. We present an overview of left ventricle segmentation algorithms on short -axis MRI. A wide variety of completely different approaches are used for cardiac segmentation , including machine learning, graph-based methods, deformable models, and low-level heuristics.
The current state-of-the-art technique is a combination of deformable models with advanced machine learning methods, such as deep learning or Markov random fields. We expect that approaches based on deep belief networks are the most promising ones because the main training process of networks with this architecture can be performed on the unlabelled data.
In order to improve the quality of left ventricle segmentation algorithms, we need more datasets with labelled cardiac MRI data in open access. Exploiting publicly available biological and biochemical information for the discovery of novel short linear motifs.

The purpose of this study was to examine differences in risk factors between newly diagnosed vs. We conducted a cross-sectional study among eligible patients scheduled for elective esophagogastroduodenoscopy EGD and patients eligible for screening colonoscopy, recruited from primary care clinics at a Veterans Affairs center.
All participants completed a survey on demographics, gastroesophageal reflux disease GERD symptoms and medication use prior to undergoing study EGD.
We compared BE cases separately to two control groups: primary care controls and endoscopy controls. Associations between risk factors and differing BE case definitions were evaluated with multivariate logistic regression models.
Likewise, the inverse association with H. GERD symptoms and H. Few differences were observed between BE cases and endoscopy controls. We found differences in the strength and profiles of risk factors for BE.
The findings support that epidemiological studies of BE should make a distinction between long and short , new and prevalent, endoscopy-only and BE with SIM as well as type of controls.

It avoids issues associated with overlapping amplicon-based Full Text Available Eucalyptus spp kraft pulp, due to its high content of hexenuronic acids, is quite easy to bleach. Therefore, investigations have been made attempting to decrease the number of stages in the bleaching process in order to minimize capital costs. Uncommon pulp treatments, such as molybdenum catalyzed acid peroxide PMo and xylanase X bleaching stages, were used.
This sequence was highly cost-effective although it only produced pulp of acceptable quality. Automatic gallbladder segmentation using combined 2D and 3D shape features to perform volumetric analysis in native and secretin-enhanced MRCP sequences.
We aimed to develop the first fully automated 3D gallbladder segmentation approach to perform volumetric analysis in volume data of magnetic resonance MR cholangiopancreatography MRCP sequences. Volumetric gallbladder analysis is performed for non-contrast-enhanced and secretin-enhanced MRCP sequences. Native and secretin-enhanced MRCP volume data were produced with a 1.
Images of coronal maximum intensity projections MIP are used to automatically compute 2D characteristic shape features of the gallbladder in the MIP images. A gallbladder shape space is generated to derive 3D gallbladder shape features, which are then combined with 2D gallbladder shape features in a support vector machine approach to detect gallbladder regions in MRCP volume data.
A region-based level set approach is used for fine segmentation. Volumetric analysis is performed for both sequences to calculate gallbladder volume differences between both sequences. The approach presented achieves segmentation results with mean Dice coefficients of 0. This is the first approach developed to detect and segment gallbladders in MR-based volume data automatically in both sequences. It can be used to perform gallbladder volume determination in epidemiological studies and to detect abnormal gallbladder volumes or shapes.
The positive volume differences between both sequences may indicate the quantity of the pancreatobiliary reflux. Salt-bridging effects on short amphiphilic helical structure and introducing sequence -based short beta-turn motifs.
Determining the minimal sequence necessary to induce protein folding is beneficial in understanding the role of protein-protein interactions in biological systems, as their three-dimensional structures often dictate their activity. Manipulating the sequence of short , moderately helical peptides can help elucidate the influences on folding. We created two new scaffolds based on a modestly helical eight-residue peptide, PT3, we previously published.
Using circular dichroism CD spectroscopy and changing the possible salt-bridging residues to new combinations of Lys, Arg, Glu, and Asp, we found that our most helical improvements came from the Arg-Glu combination, whereas the Lys-Asp was not significantly different from the Lys-Glu of the parent scaffold, PT3.
The marked 3 10 -helical contributions in PT3 were lessened in the Arg-Glu-containing peptide with the beginning of cooperative unfolding seen through a thermal denaturation. Overall, the results indicate that improvements made to short peptide scaffolds by fine-tuning the salt-bridging residues can enhance scaffold structure. Inspired by the recent spatio-temporal action localization efforts with tubelets sequences of bounding boxes , we present a new spatio-temporal action localization detector Segment -tube, which consists of sequences of per-frame segmentation masks.

The exponential multi-scale C-V model with level set inheritance and boundary inheritance is developed. The main research contributions are as follows: 1 the problems of the “holes” and “gaps” are solved when extraction coastline through the small scale shrinkage, low-pass filtering and area sorting of region.
Experiment results show that the method accelerates the acquisition of initial level set formation, shortens the time of the extraction of coastline, at the same time, removes the non-coastline body part and improves the identification precision of the main body coastline, which automates the process of coastline segmentation.
SeqEntropy: genome-wide assessment of repeats for short read sequencing. We investigated the limitation from the perspective of information theory to evaluate the effect of repeats on short -read genome assembly using idealized error-free reads at different lengths. Our results indicate that the levels of repeats in different genomes are diverse and the entropy of sequencing reads provides a measurement for the repeat structures.
Moreover, the calculation can be parallelized to scale up to large euakryotic genomes. This approach may be useful to tune the sequencing parameters to achieve better genome assemblies when a closely related genome is already available.
Accurate typing of short tandem repeats from genome-wide sequencing data and its applications. Short tandem repeats STRs are implicated in dozens of human genetic diseases and contribute significantly to genome variation and instability. Yet profiling STRs from short -read sequencing data is challenging because of their high sequencing error rates. Here, we developed STR-FM, short tandem repeat profiling using flank-based mapping, a computational pipeline that can detect the full spectrum of STR alleles from short -read data, can adapt to emerging read-mapping algorithms, and can be applied to heterogeneous genetic samples e.
We constructed an error correction model for genotyping STRs that can distinguish heterozygous alleles containing STRs with consecutive repeat numbers. Applying our model and pipeline to Illumina sequencing data with bp reads, we could confidently genotype several disease-related long trinucleotide STRs. Utilizing this pipeline, for the first time we determined the genome-wide STR germline mutation rate from a deeply sequenced human pedigree. Additionally, we built a tool that recommends minimal sequencing depth for accurate STR genotyping, depending on repeat length and sequencing read length.
This suite of tools addresses the pressing challenges surrounding STR genotyping, and thus is of wide interest to researchers investigating disease-related STRs and STR evolution. Domestic cats exhibit abundant variations in tail morphology and serve as an excellent model to study the development and evolution of vertebrate tails. Cats with shortened and kinked tails were first recorded in the Malayan archipelago by Charles Darwin in and remain quite common today in Southeast and East Asia.
To elucidate the genetic basis of short tails in Asian cats, we built a pedigree of 13 cats segregating at the trait with a founder from southern China and performed linkage mapping based on whole genome sequencing data from the pedigree.
The short -tailed trait was mapped to a 5. Validation in unrelated cats confirmed the correlation between HES7-c. In addition, some of our sampled kinked-tailed cats could not be explained by either HES7 or the Manx-related T-box, suggesting at least three independent events in the evolution of domestic cats giving rise to short -tailed traits.

Transcriptional sequencing and analysis of major genes involved in the adventitious root formation of mango cotyledon segments. A total of 74, unigenes were generated and DEGs were identified.
Candidate genes that may be involved in the adventitious root formation of mango cotyledon segment were revealed. Adventitious root formation is a crucial step in plant vegetative propagation, but the molecular mechanism of adventitious root formation remains unclear.
Adventitious roots formed only at the proximal cut surface PCS of mango cotyledon segments , whereas no roots were formed on the opposite, distal cut surface DCS. Illumina sequencing of libraries generated from these samples yielded DCS when time-matched samples were compared. Of these DEGs, were assigned to gene ontology GO classes, the majority of that was involved in cellular processes, metabolic processes and single-organism processes. Candidate genes that may be involved in the adventitious root formation of mango cotyledon segment are predicted to encode polar auxin transport carriers, auxin-regulated proteins, cell wall remodeling enzymes and ethylene-related proteins.
In order to validate RNA- sequencing results, we further analyzed the expression profiles of 20 genes by quantitative real-time PCR. This study expands the transcriptome information for Mangifera indica and identifies candidate genes involved in adventitious root formation in cotyledon segments of mango. Growing evidence suggests that the cerebellum is not only involved in motor functions, but it significantly contributes to sensory and cognitive processing as well.
In particular, it has been hypothesized that the cerebellum identifies recurrent serial events and recognizes their violations. Here we used transcranial magnetic stimulation TMS to shed light on the role of the cerebellum in short -term memory of visual sequences. In turn, cerebellar TMS did not affect recognition of highly familiar short sequences of letters or numbers.
Overall, our data suggest that the cerebellum is involved in memorizing the order in which concatenated stimuli appear, this process being important for sequence learning. Semiautomatic segmentation of aortic valve from sequenced ultrasound image using a novel shape-constraint GCV model. Purpose: Effective and accurate segmentation of the aortic valve AV from sequenced ultrasound US images remains a technical challenge because of intrinsic factors of ultrasound images that impact the quality and the continuous changes of shape and position of segmented objects.
In this paper, a novel shape-constraint gradient Chan-Vese GCV model is proposed for segmenting the AV from time serial echocardiography. Methods: The GCV model is derived by incorporating the energy of the gradient vector flow into a CV model framework, where the gradient vector energy term is introduced by calculating the deviation angle between the inward normal force of the evolution contour and the gradient vector force.
The flow force enlarges the capture range and enhances the blurred boundaries of objects. This is achieved by adding a circle-like contour constructed using the AV structure region as a constraint shape as an energy item to the GCV model through the shape comparison function. This shape-constrained energy can enhance the image constraint force by effectively connecting separate gaps of the object edge as well as driving the evolution contour to quickly approach the ideal object.
Because of the slight movement of the AV in adjacent frames, the initial constraint shape is defined by users, with the other constraint shapes being derived from the segmentation results of adjacent sequence frames after morphological filtering.
The AV is segmented from the US images by minimizing the proposed energy function. Results: To evaluate the performance of the proposed method, five assessment parameters were used to compare it with manual delineations performed by radiologists gold standards.

We discuss a new alternative for obtaining position and time coordinates from a video of a free fall experiment.
In our approach, after converting the video to a short sequence of images, the images are analyzed using a web page application developed by the author. The main advantage of the setup explained in this work, is that it is simple to use, no software license fees are necessary, and can be scaled-up to be used by a big number of students in introductory physics courses. The steps involved in the full analysis of a falling object are: we grab a short digital video of the experiment and convert it to a sequence of images, then, using a web page that includes all the necessary javascript, the student can easily click on the object of interest to obtain the x,y,t coordinates, finally, the student analyze motion using a spreadsheet.
Characterizing novel endogenous retroviruses from genetic variation inferred from short sequence reads. From Illumina sequencing of DNA from brain and liver tissue from the lion, Panthera leo, and tumor samples from the pike-perch, Sander lucioperca, we obtained two assembled sequence contigs with similarity to known retroviruses. Phylogenetic analyses suggest that the pike-perch retrovirus belongs To determine if these novel retroviral sequences originate from an endogenous retrovirus or from a recently integrated exogenous retrovirus, we assessed the genetic diversity of the parental sequences from which the short Illumina reads Full Text Available Abstract Background The orthoreoviruses are infectious agents that possess a genome comprised of 10 double-stranded RNA segments encased in two concentric protein capsids.
RdRp sequences have been determined for the prototype mammalian orthoreoviruses and for several other closely-related reoviruses, including aquareoviruses, but have not yet been reported for any avian orthoreoviruses. Alignments of these newly-determined ARV genome segments , and their corresponding proteins, were performed with all currently available homologous mammalian reovirus MRV and aquareovirus AqRV genome segment and protein sequences.
Pulmonary parenchyma segmentation in thin CT image sequences with spectral clustering and geodesic active contour model based on similarity. While the popular thin layer scanning technology of spiral CT has helped to improve diagnoses of lung diseases, the large volumes of scanning images produced by the technology also dramatically increase the load of physicians in lesion detection.
Computer-aided diagnosis techniques like lesions segmentation in thin CT sequences have been developed to address this issue, but it remains a challenge to achieve high segmentation efficiency and accuracy without much involvement of human manual intervention.
In this paper, we present our research on automated segmentation of lung parenchyma with an improved geodesic active contour model that is geodesic active contour model based on similarity GACBS. Combining spectral clustering algorithm based on Nystrom SCN with GACBS, this algorithm first extracts key image slices, then uses these slices to generate an initial contour of pulmonary parenchyma of un- segmented slices with an interpolation algorithm, and finally segments lung parenchyma of un- segmented slices.
Experimental results show that the segmentation results generated by our method are close to what manual segmentation can produce, with an average volume overlap ratio of SRComp: short read sequence compression using burstsort and Elias omega coding.
Full Text Available Next-generation sequencing NGS technologies permit the rapid production of vast amounts of data at low cost. Economical data storage and transmission hence becomes an increasingly important challenge for NGS experiments. In this paper, we introduce a new non-reference based read sequence compression tool called SRComp.
It works by first employing a fast string-sorting algorithm called burstsort to sort read sequences in lexicographical order and then Elias omega-based integer coding to encode the sorted read sequences.
SRComp has been benchmarked on four large NGS datasets, where experimental results show that it can run times faster than current state-of-the-art read sequence compression tools such as BEETL and SCALCE, while retaining comparable compression efficiency for large collections of short read sequences. SRComp is a read sequence compression tool that is particularly valuable in certain applications where compression time is of major concern. Full Text Available We examined the impact of listening context sound duration and prior presentation on the human perception of segmentation in sequences of computer music.
In addition, response lag was reduced from a first hearing to a second hearing, and following long 7 s rather than short 1 or 3 s segments. These findings point to the role of short -term memory in dynamic structural perception of computer music. Optimization of short amino acid sequences classifier. This article describes processing methods used for short amino acid sequences classification. The data processed are 9-symbols string representations of amino acid sequences , divided into 49 data sets – each one containing samples labeled as reacting or not with given enzyme.
The goal of the classification is to determine for a single enzyme, whether an amino acid sequence would react with it or not. Each data set is processed separately. Feature selection is performed to reduce the number of dimensions for each data set.
The method used for feature selection consists of two phases. During the first phase, significant positions are selected using Classification and Regression Trees.
Afterwards, symbols appearing at the selected positions are substituted with numeric values of amino acid properties taken from the AAindex database. In the second phase the new set of features is reduced using a correlation-based ranking formula and Gram-Schmidt orthogonalization.
SPDE, an evolutionary algorithm, is used to obtain optimal hyperparameters for the LS-SVM classifier, such as error penalty parameter C and kernel-specific hyperparameters. A simple score penalty is used to adapt the SPDE algorithm to the task of selecting classifiers with best performance measures values.

Reliable automatic segmentation of MR cardiac images is still an important problem in medical image processing. Although image data quality has improved considerably during the last years, this segmentation is still considered a difficult problem.
Manual segmentation is hardly an option as this is. A low false negative filter for detecting rare bird species from short video segments using a probable observation data set-based EKF method. We report a new filter to assist the search for rare bird species.
Since a rare bird only appears in front of a camera with very low occurrence e. We verify the bird body axis information with the known bird flying dynamics from the short video segment. The algorithm has been extensively tested using both simulated inputs and real video data of four representative bird species.
In the physical experiments, our algorithm has been tested on rock pigeons and red-tailed hawks with motion sequences. The area under the ROC curve is During the one-year search of ivory-billed woodpeckers, the system reduces the raw video data of Short term reproducibility of a high contrast 3-D isotropic optic nerve imaging sequence in healthy controls.
The optic nerve ON plays a crucial role in human vision transporting all visual information from the retina to the brain for higher order processing. There are many diseases that affect the ON structure such as optic neuritis, anterior ischemic optic neuropathy and multiple sclerosis.
Because the ON is the sole pathway for visual information from the retina to areas of higher level processing, measures of ON damage have been shown to correlate well with visual deficits. Increased intracranial pressure has been shown to correlate with the size of the cerebrospinal fluid CSF surrounding the ON.
These measures are generally taken at an arbitrary point along the nerve and do not account for changes along the length of the ON. We propose a high contrast and high-resolution 3-D acquired isotropic imaging sequence optimized for ON imaging.
We have acquired scan-rescan data using the optimized sequence and a current standard of care protocol for 10 subjects.
We show that this sequence has superior contrast-to-noise ratio to the current standard of care while achieving a factor of 11 higher resolution. We apply a previously published automatic pipeline to segment the ON and CSF sheath and measure the size of each individually.
We show that these measures of ON size have lower short – term reproducibility than the population variance and the variability along the length of the nerve.
We find that the proposed imaging protocol is 1 useful in detecting population differences and local changes and 2 a promising tool for investigating biomarkers related to structural changes of the ON. Full Text Available Robust gait segmentation is the basis for mobile gait analysis. A range of methods have been applied and evaluated for gait segmentation of healthy and pathological gait bouts. In this paper, we compare four prevalent gait segmentation methods in order to reveal their strengths and drawbacks in gait processing.
We considered peak detection from event-based methods, two variations of dynamic time warping from template matching methods, and hierarchical hidden Markov models hHMMs from machine learning methods. To evaluate the methods, we included two supervised and instrumented gait tests that are widely used in the examination of Parkinsonian gait.
In the first experiment, a sequence of strides from instructed straight walks was measured from 10 PD patients. In the second experiment, a more heterogeneous assessment paradigm was used from an additional 34 PD patients, including straight walks and turning strides as well as non-stride movements. The goal of the latter experiment was to evaluate the methods in challenging situations including turning strides and non-stride movements. Hence, we concluded that in the case of a predefined and homogeneous sequence of strides, all methods can be applied equally.
The hHMM also proved promising in distinguishing between strides and non-stride movements, which is critical for clinical gait analysis. Our results indicate that both the instrumented test procedure and the required stride segmentation algorithm have to be selected adequately in order to support and complement classical. Resonant magnetoelectric response of composite cantilevers: Theory of short vs.
Full Text Available The magnetoelectric effect in layered composite cantilevers consisting of strain coupled layers of magnetostrictive MS, piezoelectric PE, and substrate materials is investigated for magnetic field excitation at bending resonance.
Response optimized PE-MS layer thickness ratios are found to greatly change with operation mode shifting from near equal MS and PE layer thicknesses in the open circuit mode to near vanishing PE layer thicknesses in short circuit operation for all layer sequences.
In addition the substrate layer thickness is found to differently affect the open and short circuit ME response producing shifts and reversal between ME response maxima depending on layer sequence. The observed rich ME response behavior for different layer thicknesses, sequences , operating modes, and PE materials can be explained by common neutral plane effects and different elastic compliance effects in short and open circuit operation.
Holmium laser vs. Our goal was to analyze the outcome between holmium laser and cold knife direct visual internal urethrotomy DVIU for short-segment bulbar urethral stricture.
We conducted a prospective study comprised of male patients seen from June to December Patient followup included uroflowmetry at postoperative Day 3, as well as at three months and six months. Baseline demographics were comparable in both groups. A total of patients met the inclusion criteria and five patients were excluded due to inadequate followup.
Mean stricture length was 1. Mean operating time in Group A was Five patients in Group A had bleeding after the procedure that was managed conservatively by applying perineal compression. Three patients in Group B had fluid extravasation postoperatively.
Both holmium laser and cold knife urethrotomy are safe and equally effective in treating short-segment bulbar urethral strictures in terms of outcome and complication rate. However, holmium laser requires more expertise and is a costly alternative.
Characterization of Campylobacter jejuni applying flaA short variable region sequencing , multilocus sequencing and Fourier transform infrared spectroscopy. FTIR has been shown to serve as a valuable tool in typing An objective method to optimize the MR sequence set for plaque classification in carotid vessel wall images using automated image segmentation. Full Text Available A typical MR imaging protocol to study the status of atherosclerosis in the carotid artery consists of the application of multiple MR sequences.
Since scanner time is limited, a balance has to be reached between the duration of the applied MR protocol and the quantity and quality of the resulting images which are needed to assess the disease. In this study an objective method to optimize the MR sequence set for classification of soft plaque in vessel wall images of the carotid artery using automated image segmentation was developed.
The automated method employs statistical pattern recognition techniques and was developed based on an extensive set of MR contrast weightings and corresponding manual segmentations of the vessel wall and soft plaque components, which were validated by histological sections.
Evaluation of the results from nine contrast weightings showed the tradeoff between scan duration and automated image segmentation performance. For our dataset the best segmentation performance was achieved by selecting five contrast weightings.
The presented approach can help others to optimize MR imaging protocols by investigating the tradeoff between scan duration and automated image segmentation performance possibly leading to shorter scanning times and better image interpretation. This approach can potentially also be applied to other research fields focusing on different diseases and anatomical regions.
MATAM: reconstruction of phylogenetic marker genes from short sequencing reads in metagenomes. Advances in the sequencing of uncultured environmental samples, dubbed metagenomics, raise a growing need for accurate taxonomic assignment. Accurate identification of organisms present within a community is essential to understanding even the most elementary ecosystems.
However, current high-throughput sequencing technologies generate short reads which partially cover full-length marker genes and this poses difficult bioinformatic challenges for taxonomy identification at high resolution.
We designed MATAM, a software dedicated to the fast and accurate targeted assembly of short reads sequenced from a genomic marker of interest. The method implements a stepwise process based on construction and analysis of a read overlap graph.
It is applied to the assembly of 16S rRNA markers and is validated on simulated, synthetic and genuine metagenomes.
We show that MATAM outperforms other available methods in terms of low error rates and recovered fractions and is suitable to provide improved assemblies for precise taxonomic assignments.

Commercial flocks infected by Eimeria species parasites, including Eimeria maxima, have an increased risk of developing clinical or subclinical coccidiosis; an intestinal enteritis associated with increased mortality rates in poultry. Currently, infection control is largely based on chemotherapy or live vaccines; however, drug resistance is common and vaccines are relatively expensive.
The development of new cost-effective intervention measures will benefit from unraveling the complex genetic mechanisms that underlie host-parasite interactions, including the identification and characterization of genes encoding proteins such as phosphatidylinositol 4-phosphate 5-kinase PIP5K.
Comparative sequence analysis with the orthologous E. Unique segmental organizations and telomere-like repeats were also observed in both genomes. A number of incomplete transposable elements were detected and further scrutiny of these elements in both orthologous segments revealed interesting nesting events, which may play a role in facilitating genome plasticity in E. The current analysis provides more detailed information about the genome organization of E.
Experimental replacement of esophagus with a short segment of trachea. Segmental resection of esophagus with primary anastomosis is prohibited because of the risk of dehiscence.
We previously have shown that replacement of a segment of cervical esophagus with a tracheal segment of the same length could successfully be performed in a canine model. In this study, we sought to assess the feasibility of replacement of the esophageal defect with a shorter segment of trachea.
In five mongrel dogs weighting kg, under general anesthesia and after a cervical incision, 8 cm of the cervical esophagus was resected and replaced by a 4-cm segment of the adjacent trachea. The animals were evaluated clinically for signs and symptoms of stenosis and dehiscence and then euthanized after 2 mo of follow-up. All dogs recovered from surgery and started regular diet on the seventh postoperative day. No clinical or endoscopic sign of stenosis or voice change was seen.
Squamous metaplasia and atrophy of mucosal glands and cartilage were detected in the histopathologic examination of the replaced segments. Replacement of a cervical esophageal defect with a shorter segment of trachea can be performed successfully in dogs. This procedure can be potentially used for the treatment of cervical esophageal lesions in humans. Cutting and ablation using short -pulsed laser radiation are promising technologies to produce or repair CFRP components with outstanding mechanical properties e.
Using sophisticated laser processing strategies and avoiding excessive heating of the workpiece, a high processing quality can be achieved.
However, the interaction of laser radiation and composite material causes a notable release of hazardous substances from the process zone, amongst others carbon fiber segments or fibrous particles. In this work, amounts and geometries of the released fiber segments are analyzed and discussed in terms of their hazardous potential.
Moreover, it is investigated to what extent gaseous organic process emissions are adsorbed at the fiber segments , similar to an adsorption of volatile organic compounds at activated carbon, which is typically used as filter material. Study of the fast inversion recovery pulse sequence. With reference to fast fluid attenuated inversion recovery and fast short TI inversion recovery pulse sequence.
The fast inversion recovery fast IR pulse sequence was evaluated. We compared the fast fluid attenuated inversion recovery fast FLAIR pulse sequence in which inversion time TI was established as equal to the water null point for the purpose of the water-suppressed T 2 -weighted image, with the fast short TI inversion recovery fast STIR pulse sequence in which TI was established as equal to the fat null point for purpose of fat suppression.
Therefore, images should be taken with long TR and long TI, which are longer than TR and longer than the water null point. However, effective TE was affected by variation of the null point.
This increased in proportion to the increase in effective TE. Our evaluation indicated that the fast STIR pulse sequence can control the extensive signals from fat in a short time.
Relations between segmental and motor variability in prosodically complex nonword sequences. To assess how prosodic prominence and hierarchical foot structure influence segmental and articulatory aspects of speech production, specifically segmental accuracy and variability, and oral movement trajectory variability. Thirty individuals participated: 10 young adults, 10 children who are normally developing, and 10 children diagnosed with specific language impairment. Segmental error and segmental variability and movement trajectory variability were compared in low and high prosodic prominence conditions i.
Between-participants findings were that both groups of children showed more segmental error and segmental variability and more movement trajectory variability than did adults. A similar within-participant pattern of results was observed for all 3 groups. Prosodic prominence influenced both segmental and motor levels of analysis, with weak syllables produced less accurately and with more lip and jaw movement trajectory variability than strong syllables.
However, hierarchical foot structure affected segmental but not motor measures of speech production accuracy and variability. Motor and segmental variables were not consistently aligned. This pattern of results has clinical implications because inferences about motor variability may not directly follow from observations of segmental variability. Coval: improving alignment quality and variant calling accuracy for next-generation sequencing data.
Full Text Available Accurate identification of DNA polymorphisms using next-generation sequencing technology is challenging because of a high rate of sequencing error and incorrect mapping of reads to reference genomes. Currently available short read aligners and DNA variant callers suffer from these problems.
We developed the Coval software to improve the quality of short read alignments. Coval is designed to minimize the incidence of spurious alignment of short reads, by filtering mismatched reads that remained in alignments after local realignment and error correction of mismatched reads. The error correction is executed based on the base quality and allele frequency at the non-reference positions for an individual or pooled sample. We demonstrated the utility of Coval by applying it to simulated genomes and experimentally obtained short -read data of rice, nematode, and mouse.
Moreover, we found an unexpectedly large number of incorrectly mapped reads in ‘targeted’ alignments, where the whole genome sequencing reads had been aligned to a local genomic segment , and showed that Coval effectively eliminated such spurious alignments. We conclude that Coval significantly improves the quality of short -read sequence alignments, thereby increasing the calling accuracy of currently available tools for SNP and indel identification.

Fluorecence modulated radiotherapy with integrated segmentation to optimization. On the basis of two clinical cases, we present fluence-modulated radiotherapy with a sequencer integrated into the optimization of our treatment-planning software HYPERION. In each case, we achieved simple relations for the dependence of the total number of segments on the complexity of the sequencing , as well as for the dependence of the dose-distribution quality on the number of segments.
For both clinical cases, it was possible to obtain treatment plans that complied with the clinical demands on dose distribution and number of segments. Also, compared to the widespread concept of equidistant steps, our method of sequencing with fluence steps of variable size led to a significant reduction of the number of segments , while maintaining the quality of the dose distribution. Our findings substantiate the value of the integration of the sequencer into the optimization for the clinical efficiency of IMRT [de.
Keeping it together: Semantic coherence stabilizes phonological sequences in short -term memory. Our ability to hold a sequence of speech sounds in mind, in the correct configuration, supports many aspects of communication, but the contribution of conceptual information to this basic phonological capacity remains controversial. Previous research has shown modest and inconsistent benefits of meaning on phonological stability in short -term memory, but these studies were based on sets of unrelated words.
Using a novel design, we examined the immediate recall of sentence-like sequences with coherent meaning, alongside both standard word lists and mixed lists containing words and nonwords.
We found, and replicated, substantial effects of coherent meaning on phoneme-level accuracy: The phonemes of both words and nonwords within conceptually coherent sequences were more likely to be produced together and in the correct order.
Since nonwords do not exist as items in long-term memory, the semantic enhancement of phoneme-level recall for both item types cannot be explained by a lexically based item reconstruction process employed at the point of retrieval “redintegration”. Instead, our data show, for naturalistic input, that when meaning emerges from the combination of words, the phonological traces that support language are reinforced by a semantic-binding process that has been largely overlooked by past short -term memory research.
Tools for analyzing genetic variants from sequencing data Case study: short tandem repeats. Optic disc boundary segmentation from diffeomorphic demons registration of monocular fundus image sequences versus 3D visualization of stereo fundus image pairs for automated early stage glaucoma assessment.
Despite the current availability in resource-rich regions of advanced technologies in scanning and 3-D imaging in current ophthalmology practice, world-wide screening tests for early detection and progression of glaucoma still consist of a variety of simple tools, including fundus image-based parameters such as CDR cup to disc diameter ratio and CAR cup to disc area ratio , especially in resource -poor regions.
Reliable automated computation of the relevant parameters from fundus image sequences requires robust non-rigid registration and segmentation techniques. Recent research work demonstrated that proper non-rigid registration of multi-view monocular fundus image sequences could result in acceptable segmentation of cup boundaries for automated computation of CAR and CDR.
This research work introduces a composite diffeomorphic demons registration algorithm for segmentation of cup boundaries from a sequence of monocular images and compares the resulting CAR and CDR values with those computed manually by experts and from 3-D visualization of stereo pairs. Our preliminary results show that the automated computation of CDR and CAR from composite diffeomorphic segmentation of monocular image sequences yield values comparable with those from the other two techniques and thus may provide global healthcare with a cost-effective yet accurate tool for management of glaucoma in its early stage.
We demonstrate that during capture, the bait-hybridized library molecules add additional flanking library sequences iteratively, such that baits limited to targeting relatively short regions e.
Our findings suggest that some of the off-target sequences derived in capture experiments are non-randomly enriched, and that CapFlank will facilitate targeted enrichment of large contiguous sequences with minimal prior Spreadsheet-based program for alignment of overlapping DNA sequences.
Molecular biology laboratories frequently face the challenge of aligning small overlapping DNA sequences derived from a long DNA segment. Here, we present a short program that can be used to adapt Excel spreadsheets as a tool for aligning DNA sequences , regardless of their orientation. The program runs on any Windows or Macintosh operating system computer with Excel 97 or Excel The program is available for use as an Excel file, which can be downloaded from the BioTechniques Web site.
Upon execution, the program opens a specially designed customized workbook and is capable of identifying overlapping regions between two sequence fragments and displaying the sequence alignment. It also performs a number of specialized functions such as recognition of restriction enzyme cutting sites and CpG island mapping without costly specialized software.
RFLP analysis revealed restriction site variation for all three segments in Atlantic salmon. Eleven haplotypes were detected in a screening Choice of reference sequence and assembler for alignment of Listeria monocytogenes short -read sequence data greatly influences rates of error in SNP analyses.
Full Text Available The wide availability of whole-genome sequencing WGS and an abundance of open-source software have made detection of single-nucleotide polymorphisms SNPs in bacterial genomes an increasingly accessible and effective tool for comparative analyses.
Thus, ensuring that real nucleotide differences between genomes i. The choices researchers make regarding the generation and analysis of WGS data can greatly influence the accuracy of short -read sequence alignments and, therefore, the efficacy of such experiments.
We studied the effects of some of these choices, including: i depth of sequencing coverage, ii choice of reference-guided short -read sequence assembler, iii choice of reference genome, and iv whether to perform read-quality filtering and trimming, on our ability to detect true SNPs and on the frequencies of errors.
We performed benchmarking experiments, during which we assembled simulated and real Listeria monocytogenes strain short -read sequence datasets of varying quality with four commonly used assemblers BWA, MOSAIK, Novoalign, and SMALT, using reference genomes of varying genetic distances, and with or without read pre-processing i. We found that assemblies of at least fold coverage provided the most accurate results.
Finally, we show that whether read pre-processing improves SNP detection depends upon the choice of reference sequence and assembler. In total, this study demonstrates that researchers. Geo Segmenter : A statistically learned Chinese word segmenter for the geoscience domain. Unlike English, the Chinese language has no space between words. Segmenting texts into words, known as the Chinese word segmentation CWS problem, thus becomes a fundamental issue for processing Chinese documents and the first step in many text mining applications, including information retrieval, machine translation and knowledge acquisition.
However, for the geoscience subject domain, the CWS problem remains unsolved.

Tissue stem cells are found in the bodies of children and adults. They are a minute fraction of the cells less than 1 per that make up organs and tissues like the liver, cornea, skin, muscles, hair, brain, bone marrow, and umbilical cord blood. Despite their small fraction, they are responsible for continuously renewing and repairing the body. A long-standing challenge in stem cell biomedicine has been the lack of a means to count tissue stem cells specifically and determine their specific dose for stem cell transplantation therapies.
Because tissue stem cells are a minor fraction of tissue cells, even in the best enriched populations, and there are no known biomarkers that recognize tissue stem cells specifically, previously it has not been possible to count therapeutic tissue stem cells. It can be used to determine the dose of therapeutic tissue stem cells like hematopoietic stem cells and mesenchymal stem cells.
It can be use to monitor and optimize tissue stem cell number in manufacturing processes. It can be used to windows 10 1703 download iso italy vstm agents that affect tissue stem cell function and viability either positively or negatively.
