The purpose of this study is to examine the relationship between mortality and stay times in intensive care and hematocrit value as of the time of application with trauma scores and hemodynamic measurements in patients with thorax and abdominal injuries due to stab wounds in the intensive care unit. Sosyodemographic data, vital signs, blood parameters, characteristics of injuries recorded and G...

Can Plasma Skimming or Inconstancy of Regional Hematocrit Introduce Serious Errors in Regional Cerebral Blood Flow Measurements or Their Interpretation? • Recent reports indicate that in cases of elevated plasma or blood viscosity, red cell velocity through the cerebral microcirculation is unimpaired while plasma transit is retarded. One explanation may be that plasma skimming is increased, wit...

Background: Anemia is common throughout the world, remarkably in developing countries. Our aim is to calculate normal hemoglobin and other hematological indices in southwest of Iran. Materials and Methods: A random selection of 500 healthy males and 500 healthy females was done in the age group of 13 to 65 years. A complete blood count (CBC) was performed in all participants. Results: Hemoglobi...

HD patients, or its accumulation due to renal failure, logically inhibits the iron release by macrophages, limiting its availability for erythropoiesis [4] . In accordance with the negative correlation between prohepcidin and hematocrit are the findings of Dallalio et al. [5] , who in a recent in vitro study detected that hepcidin can contribute to anemia not only through an effect on iron meta...

Although a number of clinical studies have shown that increased hematocrits are associated with improved outcomes in terms of cognitive function, reduced left ventricular hypertrophy, increased exercise tolerance, and improved quality of life, the optimal hematocrit level associated with survival has yet to be determined. The association between hematocrit levels and patient mortality was retro...

BACKGROUND The Precision Xtra(®) meter is a promising low cost electrochemical point-of-care unit for measuring blood glucose concentration ([gluc]) in cattle blood. The meter uses an algorithm that assumes the intra-erythrocyte [gluc] equals the plasma [gluc] on a molal basis, and that the hematocrit is similar in humans and cattle. OBJECTIVES The primary objective was to determine the accur...

The effect of anemia on the coronary microcirculation was studied in young male rats. Chronic anemia resulted in increased left ventricular end-diastolic pressure and decreased functional reserve. Cardiac mass in anemic animals increased by 25%. Capillary and arteriolar densities in these hearts remained unchanged, indicating angiogenesis in this experimental situation (estimated aggregate capi...

The 'cost of reproduction' (i.e. the trade-off between current reproduction and future fecundity and/or survival) is a central concept in life history theory, yet we still know very little about the physiological mechanisms underlying such costs. Recently it has been recognized that reproduction itself or the regulatory (hormonal) mechanisms underlying reproduction might result in 'costs' (cf. ...

The paper is devoted to the comparison of different one-dimensional models blood flow. In such models, non-Newtonian property considered. It demonstrated that for large arteries, small parameter observed in and perturbation method can be used analytical solution. paper, simplified nonlinear problem semi-infinite vessel with constant properties solved analytically, solutions are compared. effect...
