BACKGROUND Low intensity ultrasound (US) has some well-known bio-effects which are of great importance to be considered. Objective: We conducted the present study to investigate the effects of low intensity continuous ultrasound on blood cells count in rat. METHODS Rats were anesthetized and blood samples were collected before US exposure. Then, they were exposed to US with nominal intensity ...

The study investigated the effect of combined sprint and resistance training (CSRT) on red blood cell (RBC) count, hemoglobin (Hb), hematocrit (Hct), plasma volume (PV) variation at rest during exercise. Twenty-eight moderately trained were randomly assigned into a young (YT), control (YC), middle-aged (MAT), (MAC) group. Before (P1), after (P2) CSRT, samples collected At P1, Hct was significan...

Retrograde autologous priming (RAP) has been routinely applied in cardiac pediatric cardiopulmonary bypass (CPB). However, this technique is performed in pediatric patients weighing more than 20 kg, and research about its application in pediatric patients weighing less than 20 kg is still scarce. This study explored the clinical application of RAP in CPB in pediatric patients undergoing cardiac...

The prevalence of intensive insulin and restrictive blood use protocols in burn centers is unknown, which may be problematic as the combined impact of these therapies is to concomitantly increase the prevalence of anemia and hypoglycemia in intensive care unit patients. Such a development is important because point-of-care (POC) glucometers report erroneously high values in the presence of low ...

Hookworm infection is associated with anemia, especially among children and deworming can improve anemic status; however, little information is available about the degree to which anemia improves after deworming. We chose hookworm-endemic rural areas of Thailand, Nan Province in the north, Kanchanaburi Province in the west and Nakhon Si Thammarat Province in the south, to evaluate this problem....

Lower body negative pressure (LBNP), a model of hemorrhage (Hem), shifts blood to the legs and elicits central hypovolemia. This study compared responses to LBNP and actual Hem in sedated baboons. Arterial pressure, pulse pressure (PP), central venous pressure (CVP), heart rate, stroke volume (SV), and +dP/dt were measured. Hem steps were 6.25%, 12.5%, 18.75%, and 25% of total estimated blood v...

OBJECTIVES The atherosclerotic process in arteries is correlated with the local wall shear stress (WSS). Plaque development particularly occurs in regions with recirculation (ie, where the WSS oscillates). We investigated the effects of non-Newtonian blood viscosity, variations in flow rate, and vessel diameter on wall phenomena in a carotid bifurcation model. MATERIALS AND METHODS The flow t...

To evaluate the influence of mating behavior on cardiac function, changes in heart rate (HR), electrocardiogram (ECG), hematocrit (Hct) and serum concentration of alpha-atrial natriuretic peptide (alpha-ANP) were evaluated in 10 clinically sound Thoroughbred stallions before and after mating behavior. The stallions were submitted twice to experimental pseudomating in the same month in 2009 and ...

PURPOSE Patients treated with propranolol, a nonselective β-adrenoceptor antagonist, develop severe anaphylaxis, but the mechanism remains unknown. We determined effects of β₁- and β₂-adrenoceptor antagonists on the anaphylaxis-induced increase in vascular permeability in mice. METHODS In anesthetized ovalbumin-sensitized C57BL mice, mean arterial blood pressure (MBP) was measured, and Evans ...

Objective: The objective of this study was to estimate the genetic parameters for worm resistance (WR) and associated characteristics, using linear-threshold animal model via Bayesian inference in single- multiple-trait analyses.Methods: Data were collected from a herd Santa Inês breed sheep. All information with animals submitted natural contamination conditions. data (number eggs per gram fec...
