Background: Hypertension is considered an independent risk factor for cardiovascular mortality in diabetic patients. The present study was designed to determine the role of gamma amino butyric acid B (GABAB) receptor and L-arginine (L-Arg) in GABA-induced vasorelaxation in normal and streptozotocin-induced diabetic rat vessels. Methods: Diabetes was induced by a single i.p. injection of strepto...

Introduction: The present study used a histological evaluation method to examine the effects of pentoxifylline (PTX) on healing an experimentally-induced pressure sore in a rat model. Materials and Methods: There were 36 adult male rats used in this study. Under general anesthesia and sterile conditions, we used forceps to create one pressure sore on each rat. A double layer of folded skin...

Methods 24 post-operative cardiac patients were prospectively enrolled. Arterial pressure and central venous pressure was measured invasively. Cardiac output (CO) was measured with a non-calibrated LiDCOplus monitor (LiDCO, Cambridge). Pmsf was measured using the stop-flow arterial venous equilibrium pressure method (1). Sublingual microcirculation was recorded with CytoCam (Braedius Medical, A...

The gas molecules appear to have zero average velocity in the rest frame of the pressure vessel, so it appears that they have zero average momentum in this frame. Of course, the gas molecules exert a force F = AP on a portion of area A of the wall of the pressure vessel, and since force equals the time rate of change of momentum, we can say that the gas can transmit momentum without possessing ...

Freeze casting of composite PIM-1 and activated carbon hydrogen adsorbent monoliths, from chloroform, toward high-strength pressure vessel inserts.

BACKGROUND Research into the causes of small-vessel stroke has been hindered by technical constraints. Cases of intracerebral hemorrhage occurring in unusual clinical contexts suggest a causal role for sudden increases in blood pressure and/or cerebral blood flow. CASE DESCRIPTION We describe a fatal primary thalamic/brain stem hemorrhage occurring in the context of sudden emotional upset. At...

A thermodynamic model has been developed to calculate burning speed and entropy production of transient expending spherical laminar flame in an enclosed vessel. The model also predicts the particle trajectories of both unburned and burned gases in the vessel. The input to this model is the dynamic pressure rise due to combustion process. The unburned gases are divided into three regions: The co...
