BACKGROUND Anecdotal beliefs and limited research suggest variable patterns of mortality in age, size, and breed cohorts of dogs. Detailed knowledge of mortality patterns would facilitate development of tailored health-maintenance practices and contribute to the understanding of the genetic basis of disease. HYPOTHESIS/OBJECTIVES To describe breed-specific causes of death in all instances of ...

PURPOSE Previous studies have shown atlas-based segmentation using a single best matched (SBM) atlas subject can significantly reduce contouring time. A new multi-atlas approach has been shown to provide greater accuracy than SBM for cancer of the head and neck. The goal of this study was to evaluate the multi-atlas technique for lung cancer treatment planning. METHODS An institution's SBRT l...

OBJECTIVE It is unclear whether atlas-based parcellation is suitable in aging cohorts because age-related brain changes confound the performance of automatic methods. We assessed atlas-based parcellation of the prefrontal lobe in an aging population using visual assessment and volumetric and spatial concordance. METHODS We used an atlas-based approach to parcellate brain MR images of 90 non-d...

background and aims: finding prevalence of chicken anemia virus (cav) infection in native chickens is necessary to avoid transmission of infection to commercial flocks. in this paper we attempt to describe molecular detection of chicken anemia virus in native larry-breed chickens in chaharmahal-va-bakhtiyari province in iran for the first time. materials and methods: blood samples were collecte...

the booroola fecundity gene (fecb) and growth differentiation factor 9 (gdf9) gene belong to the transforming growth factor β (tgf-β) superfamily. the mutations of these genes have additive effects on the prolificacy in sheep. the aim of the present study was to determine the possible mutations of fecb and fecgh genes in lory sheep breed of the lorestan province, iran. sixty blood samples were ...

Medical imaging has shown that, during early development, the brain undergoes more changes in size, shape and appearance than at any other time in life. A better understanding of brain development requires a spatio-temporal atlas that characterizes the dynamic changes during this period. In this paper we present an approach for constructing a 4D atlas of the developing brain, between 28 and 44 ...

Summary: ATLAS (Automatic Tool for Local Assembly Structures) is a comprehensive multi-omics data analysis pipeline that is massively parallel and scalable. ATLAS contains a modular analysis pipeline for assembly, annotation, quantification and genome binning of metagenomics and metatranscriptomics data and a framework for reference metaproteomic database construction. ATLAS transforms raw sequ...

a crossbreeding experiment involving four iranian fat-tailed sheep breeds, namely kurdi (k), chaal (c), afshari (a) and sanjabi (s) was carried out to determine the ram breed effects on productivity of kurdi fat-tailed ewes (k) under extensive production system. a total of 475 kurdi ewes were mated to 24 rams from four breeds producing 454 lambs including pure kurdi, kk, (116 lambs), afshari × ...

Multi-atlas registration-based segmentation has recently become a popular technique in medical imaging. Since the quality of individual atlas segmentations affect the quality of the results, atlas selection and atlas fusion have become important areas of research for multi-atlas segmentation. In this paper, we present an automatic technique that approximately calculates the quality of registrat...

Longissimus muscle area, shear force measure, and sensory panel scores for flavor, juiciness, and tenderness, and marbling score were obtained from 682 steer carcasses, resulting from crosses among five Bos taurus and Bos indicus breeds. The single-trait model used included birth year and as covariates breed fractions, weaning age, and days on feed. The numerator relationship matrix was for 1,3...
