We tested the hypothesis that Cache Valley Virus (CVV), an endemic North American bunyavirus, may be involved in the pathogenesis of human neural tube defects. This investigation followed a 1990 and 1991 south Texas outbreak of neural tube defects with a high prevalence of anencephaly and the demonstration in 1987 that in utero infection by CVV was the cause of outbreaks of central nervous syst...
Recently there has been an emphasis on applying numerical modeling, with varying degrees of complexity, to the study of the notorious sensitivity of the pulse tube cryocooler to off-axis operation. Previous work has demonstrated the suitability of applying multi-dimensional CFD simulation to the pulse tube cryocooler both as a whole and at the component level for qualitative and quantitative an...
Chest tubes and their accompanying pleural drainage units continue to present challenging questions regarding their optimal use. Appropriate chest tube size selection to accommodate the clinical situation is key, especially in the setting of large pleural air leaks lest a tension pneumothorax ensue. Connection of an appropriate pleural drainage unit to the chest tube is equally important to obv...
Vertebrate central nervous system develops from a neural tube derived from the embryonic ectoderm. In mouse, the neural tube around embryonic day 10 primarily consists of neural precursor cells (NPCs). During the development of embryonic central nervous system, NPCs proliferate and migrate outward; thus later stages show NPCs toward the lumen of the neural tube and neurofilament-positive differ...
Two manual liquid medium systems, the Mycobacteria Growth Indicator Tube (MGIT) and MB Redox tube systems, were evaluated in comparison to the radiometric BACTEC-460 semiautomated system for recovery of Mycobacterium tuberculosis from sputum specimens. The highest level of recovery, from a total of 77 culture-positive specimens, occurred with the BACTEC-460 system (92.2%), followed by the MB Re...
Abstract The paper presents the solution of conjugated heat exchange problem in a cylindrical ribbed tube using open integrated platform OpenFOAM. obtained results allow estimating fluid heating along channel as well temperature difference on walls tube. It is shown that minimum observed center tube, and maximum one closer to walls.
