Development of the musculoskeletal system requires precise integration of muscles, tendons and bones. The molecular mechanisms involved in the differentiation of each of these tissues have been the focus of significant research; however, much less is known about how these tissues are integrated into a functional unit appropriate for each body position and role. Previous reports have demonstrate...
Triparanol, an inhibitor of desmosterol Delta24 reductase, produces a high rate of limb malformations in rat fetuses exposed at gestational day 10 (gd 10) to a single oral dose (150-200 mg/kg) given to the pregnant dam. AY9944, another efficient distal inhibitor of cholesterol biosynthesis that blocks dehydrocholesterol Delta7 reductase, produces a similar degree of cholesterol depletion but fe...
Algorithmic skeleton has received attention as an efficient method of parallel programming in recent years. Using the method, the programmer can implement parallel programs easily. In this study, a set of efficient algorithmic skeletons is introduced for use in implementing parallel genetic algorithm (PGA).A performance modelis derived for each skeleton that makes the comparison of skeletons po...
Parent-of-origin-dependent (epi)genetic factors are important determinants of prenatal development that program adult phenotype. However, data on magnitude and specificity of maternal and paternal genome effects on fetal bone are lacking. We used an outbred bovine model to dissect and quantify effects of parental genomes, fetal sex, and nongenetic maternal effects on the fetal skeleton and anal...
INTRODUCTION Ollier's disease is a rare nonhereditary disorder characterized by multiple enchondromas with a predilection for unilateral distribution. Malignant changes in Ollier's disease may occur in adult patients. Radionuclide bone scanning is one method used to assess lesions depicted on radiographs or magnetic resonance images that are presumed to be enchondromas. Also, a bone scan may gi...
the alternative double bonds and conjugation in the polyene compounds are one of the main properties in these compounds. each carbon-carbon bonds in a polyene compound along the chain has appreciable double-bond character. the p-electrons are therefore not localized but are relatively free to move throughout the entire carbon skeleton as an one-dimensional box. the skeleton be considered as a r...
Assistance and rehabilitation robotic platforms must have precise sensory systems for human–robot interaction. Therefore, human pose estimation is a current topic of research, especially the safety collaboration evaluation biomarkers. Within this field low-cost marker-less estimators OpenPose Detectron 2 has received much attention their diversity applications, such as surveillance, sports, vid...
BACKGROUND Orthopedic injuries occurring in Operations Iraqi Freedom and Enduring Freedom (OIF/OEF) are complicated by infections with multidrug resistant bacteria. We describe demographics and microbiology of OIF/OEF casualties with primary and recurrent osteomyelitis. METHODS A retrospective cohort study was performed of OIF/OEF casualties admitted to our facility from February 1, 2003 to A...
Vertebrate Pax genes encode a family of transcription factors that play important roles in embryonic patterning and morphogenesis. Two closely related Pax genes, Pax-1 and Pax-9, are associated with early axial and limb skeleton development. To investigate the role of these genes in cartilage formation we have examined the expression profiles of Pax-1 and Pax-9 in developing chick limb mesenchy...
