1. Possible Effects of Oriented Magnetic Fields on Human Blood Pressure
Abstract Background: There have been scattered reports indicating the possibility that applied magnetic fields can lower human blood viscosity, which has been considered as encouraging for decreasing blood pressure as a result of greater fluidity. Additional motivation comes from partial studies in animals showing some response of vascular variables to magn

2. Enhanced external counterpulsation improves cardiac function in Beagles after cardiopulmonary resuscitation
The aim of this study was to investigate the influence of enhanced external counterpulsation (EECP) on the cardiac function of beagle dogs after prolonged ventricular fibrillation. Twenty-four adult male beagles were randomly divided into control and EECP groups. Ventricular fibrillation was induced in the animals for 12 min, followed by 2 min of cardiopulmo

3. Erythrocytes morphology and hemorheology in severe bacterial infection
BACKGROUND Severe bacterial infections initiate inadequate inflammation that leads to disseminated intravascular coagulation and death. OBJECTIVES To evaluate the influence of bacterial infection on blood viscosity and red blood cells (RBCs) morphology, and the ability of Calotropis procera proteins (CpLP) to prevent the patho-hemorheology in infected an

4. The Role of ß-Mannanase (Hemicell) in Improving Poultry Productivity, Health and Environment
ABSTRACT The poultry nutritionists constantly attempt to identify and alleviate the factors responsible for adverse effects on nutrient utilization and production performance in avian species, which are necessary for successful productivity of poultry. Enhanced feed utilization can reduce levels of some nutrients in the diet with concomitant mitigation in nu

5. Dental implant surfaces treated with phosphoric acid can modulate cytokine production by blood MN cells
Abstract: The study characterizes dental implant surfaces treated with phosphoric acid to assess the effects of acid treatment on blood cells and correlate them with cytokine levels. The implant surfaces examined were divided into untreated metal surface (US; n = 50), metal surface treated with phosphoric acid (ATS; n = 50) and cement surface (CS; n = 50) gr

6. Effects of a physical fitness program on memory and blood viscosity in sedentary elderly men
The aim of this study was to investigate the effects of a 6-month exercise program on cognitive function and blood viscosity in sedentary elderly men. Forty-six healthy inactive men, aged 60–75 years were randomly distributed into a control group (n=23) and an experimental group (n=23). Participants underwent blood analysis and physical and memory evaluati

7. Exogenous normal lymph alleviates microcirculation disturbances and abnormal hemorheological properties in rats with disseminated intravascular coagulation
Disturbances of the microcirculation and abnormal hemorheological properties are important factors that play an important role in disseminated intravascular coagulation (DIC) and result in organ dysfunction or failure. In the present study, we established an animal model of DIC using intravenous Dextran 500 in rats, and used exogenous normal lymph correspond

8. Viability of mesenchymal stem cells during electrospinning
Tissue engineering is a technique by which a live tissue can be re-constructed and one of its main goals is to associate cells with biomaterials. Electrospinning is a technique that facilitates the production of nanofibers and is commonly used to develop fibrous scaffolds to be used in tissue engineering. In the present study, a different approach for cell i

9. OS EFEITOS DO TREINAMENTO FÍSICO COMBINADO SOBRE AS FUNÇÕES COGNITIVAS DE IDOSOS SAUDÁVEIS. / The effect of combined physical training on the cognitive functions in the health elderly.
Entre as alterações inerentes ao envelhecimento pode-se observar o surgimento do declínio cognitivo. Contudo, uma vida saudável com a prática de exercícios físicos parece gerar um efeito protetor contra o declínio cognitivo nos idosos. Segundo a literatura, tanto os exercícios aeróbios quanto os resistidos, quando praticados isoladamente, parecem b

10. Avaliação da responsividade cardiovascular por meio da variação de pulso com diferentes fluídos em modelo experimental de hemodiluição normovolêmica aguda / Assessment of cardiovascular responsiveness through variation in pulse with different fluids in an experimental model of acute normovolemic hemodilution
Background: Pulse pressure variation (PPV), have been shown to be useful tools to indicate fluid responsiveness in clinical and experimental studies. However, this parameter has not been adequately explored in situations of acute variation of blood viscosity, as happens in acute normovolemic hemodilution (ANH). The purpose of this research was to compare the

11. Microplate reader analysis of triatomine saliva effect on erythrocyte aggregation
Our hypothesis is that the action of aggregating and disaggregating substances in the blood can be detected and quantified by the Microplate Reader. To ascertain the validity of this hypothesis, we selected two types of blood: one that naturally presents erythrocyte aggregation (pig blood) and the other that does not present aggregation (bovine blood). One i

12. Egg traits and physiological neonatal chick parameters from broiler breeder at different ages
This investigation was carried out to study egg traits (weight, specific gravity and eggshell thickness), and neonatal chick parameters (weight, blood, cardiac and lung parameters) from breeder at different ages. After hatching, neonatal chicks, male and female, from broiler breeder at three different ages (30, 45 and 60 weeks) were sacrificed and blood (red
