The temporal bone is a part of the lateral skull surface that contains organs responsible for hearing and balance. Mastering surgery challenging because this complex microscopic three-dimensional anatomy. Segmentation intra-temporal anatomy based on computed tomography (CT) images necessary applications such as surgical training rehearsal, amongst others. However, segmentation due to similar intensities complicated anatomical relationships among critical structures, undetectable small...

Abstract Controlling off-target editing activity is one of the central challenges in making CRISPR technology accurate and applicable medical practice. Current algorithms for analyzing do not provide statistical quantification, are sufficiently sensitive separating signal from noise experiments with low rates, address detection translocations. Here we present CRISPECTOR, a software tool that supports quantification on- genome-editing NGS data using paired treatment/control experiments. In...

CRISPR-Cas technology has revolutionized gene editing, but concerns remain due to its propensity for off-target interactions. This, combined with genotoxicity related both CRISPR-Cas9-induced double-strand breaks and transgene delivery, poses a significant liability clinical genome-editing applications. Current best practice is optimize parameters in preclinical studies. However, quantitative tools that measure interactions are costly time-consuming, limiting the practicality of screening...

Abstract RAG2 -SCID is a primary immunodeficiency caused by mutations in Recombination-activating gene 2 (RAG2) , intimately involved the process of lymphocyte maturation and function. ex-vivo manipulation patient’s own hematopoietic stem progenitor cells (HSPCs) using CRISPR-Cas9/rAAV6 editing could provide therapeutic alternative to only current treatment, allogeneic cell transplantation (HSCT). Here we show an innovative correction strategy that replaces entire endogenous coding sequence...

Energy and stimulant drinks which contain caffeine provide enlivening effects, reduce fatigue improve concentration endurance. However, consumers may also experience physical psychological side effects as a result of excessive consumption within these drinks. Caffeine is known to exacerbate or induce some psychiatric conditions such anxiety, panic attacks, psychosis mania. Here we discuss case acute suicidality following sleep deprivation after the popular energy drink. We are concerned that...

Hypothesis: To characterize anatomical measurements and shape variation of the facial nerve within temporal bone, to create statistical models (SSMs) enhance knowledge bone anatomy aid in automated segmentation. Background: The is a fundamental structure otologic surgery, detailed anatomic with surgical experience are needed avoid its iatrogenic injury. Trainees can use simulators practice techniques, however manual segmentation required develop simulations be time consuming. Consequently,...

Recently, biomechanics ISJ have been investigated using finite-element (FE) modelling, simplified geometry. objective present study was investigate feasibility synchrotron-radiation phase-contrast imaging (SR-PCI) in visualising ultrastructure. Three human cadaveric ISJs were dissected and scanned SR-PCI at 0.9 µm isotropic voxel size. One samples previously 9 images visually...

Abstract The clinical problem of whether to stop antidepressants when patients develop mania is looked at in the light existing practice and advice both UK USA. It concluded that based more on an empirical than a scientific basis. literature subject reviewed with especial reference questions actually cause mania, they interfere treatment discontinuing them stops withdrawal causes mania. Finally case notes study conducted by one authors summarized recommendations for further research are made.
