Rogausch, Heinz, Adriana Del Rey, Jörg Oertel, and Hugo O. Besedovsky. Norepinephrine stimulates lymphoid cell mobilization from the perfused rat spleen via b-adrenergic receptors. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R724–R730, 1999.—The possibility that norepinephrine (NE) influences lymphoid cell outflow independently of its vasoconstrictor action was investigated ...

In order to better understand the performance of screen channel liquid acquisition devices (LADs) in liquid oxygen (LOX), a computational fluid dynamics (CFD) simulation of LOX passing through a LAD screen channel was conducted. In the simulation, the screen is taken as a ‘porous jump’ where the pressure drop across the screen depends on the incoming velocity and is formulated by Δp = Av + Bv. ...

It has been shown that cerebral oxygen consumption and blood flow are normal and cerebral vascular resistance is increased in patients with essential hypertension (1). Clinicians have questioned the advisability of lowering arterial pressures in hypertensive patients because of the possible untoward effects consequent to decreased cerebral blood flow (2, 3). We have studied the effect of hypote...

To elucidate the basis for the drop in pressure from large artery to vein, Jean Léonard Marie Poiseuille (1797-1869) undertook a series of seminal studies that defined the laws of fluid flow in tubes of uniform cross-section and that identified the microcirculation as the major site of the resistance to flow [1, 2]. While best known for his meticulous experimental studies of viscous flow in gla...

Blood flow during "resting conditions" and during noradrenaline infusion were studied by the labeled microsphere technique in dimethylbenz(a)anthracene-induced mammary tumors, skin, muscle, and lung in the rat. Intratumoral distribution of flow was studied by autoradiography of spheres trapped in the vascular beds of the tumors. Histological examination was performed and correlated to the blood...

Physiol. 221(l): 329-334. 1971.Renal hemodvnamic and urine flow responses to infusions of hyperoncotic dextran solutions have been studied in anesthetized dogs. Following infusion of 300-500 ml of a 12yh dextran solution, the renal blood flo...

heat and mass transfer, in this paper, is considered in one-row heat exchanger, that fins are hotter than air flow and water is added to fins. related governing equations are derived by analyzing a two-dimension model in a unique cell of a heat exchange. these equations are numerically solved by finite difference method. heat transfer and efficiency under partially wet surface are calculated by...

COFFMAN, JAY D., AND PETER ALLY. Hyperventilation and human calf blood $0~. Am. J. Physiol. 21 I (5): 1255-1260. rg66.-Calf blood flow was measured in normal subjects by venous occlusion plethysmography, and capillary blood flow by the disappearance rate of an intramuscular injection of NaI131 before and during hyperventilation at 30 breaths/min for 3 min. Hyperventilation with room air produce...

BACKGROUND/AIM Any organs functioning directly depends on vascularization. It applies also to the uterus and ovary which go through changes of vascularization during a menstruation cycle. The aim of this investigation was to determine differences in intrauterine and ovarian stromal arterioral blood flow on basal ultrasound examination (day 2-4) between spontaneous ovulatory and anovulatory cycl...

Shunt malfunction in adult and pediatric populations continues to be a perplexing problem. We examined artificial cerebrospinal fluid flow differential between adult and pediatric shunt systems. Flow through adult and pediatric-sized catheters was compared with artificial CSF using shunt systems containing new catheters, explanted catheters, 2-piece catheters, 3-piece catheters and with varying...
