An urgent cesarean section was performed under spinal anesthesia with the chest drain in see more situ. During her follow-up the thoracic computed tomography revealed a bulla at the lower lobe of the right hemithorax. We performed right thoracotomy and bullectomy.”
“A numerical study has been executed to analyze the effects of Reynolds and Prandtl number on mixed convective flow and heat transfer characteristics inside a ventilated cavity in presence of a heat-generating solid circular obstacle placed at the center. The inlet opening is at the bottom of the left wall, while the outlet one is at the top of the right wall and all the walls of the cavity are considered to be adiabatic. Galerkin weighted residual

finite element method is used to solve the governing equations of mass, momentum and energy. Results are presented in terms of streamlines, isotherms, the average Nusselt number, the Drag force and the average fluid temperature in the cavity for different combinations of controlling parameters namely, Reynolds number, Prandtl number and Richardson number. The results indicate that

the flow and thermal fields as well as the heat transfer rate, the Drag force and the average fluid temperature in the cavity depend significantly on the mentioned parameters. (C) 2011 Elsevier Inc. All rights reserved.”
“The reactivity of human fetoplacental arteries is regulated by humoral and local factors of maternal and fetal origin. The chorioallantoic (CA) arteries buy Sapanisertib of bird embryos are homologous to fetoplacental arteries and fulfill

the same gas-exchange purpose without maternal influences, but their reactivity has not been studied in detail. In the present study we hypothesized that CA arteries would respond to vasoactive factors similarly to fetoplacental arteries and the response would change during development between maximal vascular CA expansion (15 of the 21 days incubation period) and prior to hatching. Therefore, we analyzed the reactivity of third order arteries (similar to 200 mu m) from the CA membrane of 15 and 19 day chicken embryos. CA arteries contracted in response to K(+), the thromboxane A(2) mimetic U46619, endothelin-1, acetylcholine and acute hypoxia, but showed no reaction to alpha-adrenergic stimulation (phenylephrine). The nitric oxide donor sodium nitroprusside, the adenylyl cyclase MK-2206 ic50 agonist forskolin, and the beta-adrenergic agonist isoproterenol relaxed CA arteries precontracted with K(+) or U46619. The contraction evoked by acetylcholine and the relaxations evoked by sodium nitroprusside and isoproterenol decreased with incubation age. In conclusion, CA arteries share many characteristics with human fetoplacental arteries, such as pronounced relaxation to beta-adrenergic stimuli and hypoxic vasoconstriction. Our study will be the foundation for future studies to explain disparate and common responses of the CA and fetoplacental vasculature.
