The antioxidant enzyme system helps protect against intense exercise-induced oxidative damage and is related to the physical status of athletes. Evidence suggests that intestinal microbiota may be an important environmental factor associated with host metabolism, physiology, and antioxidant endogenous defense. However, evidence of the effect of gut microbiota status on ...

To date, few studies have looked at the energy expenditure (EE) of individual resistance training (RT) exercises. The purpose of this study was to evaluate the EE of four modes of RT (push-ups, curl-ups, pull-ups, and lunges) using two different calculation methods for estimating EE. Twelve healthy males with a ...

Cardiovascular patients consult doctors for advice regarding regular exercise, whereas obese patients must self-manage their weight. Because a system for permanently monitoring and tracking patients' exercise intensities and workouts is necessary, a system for recognizing gait and estimating walking exercise intensity was proposed. For gait recognition analysis, αβ filters were ...

It has been known for more than 4 decades that exercise causes increases in skeletal muscle mitochondrial enzyme content and activity (i.e., mitochondrial biogenesis). Increasing evidence now suggests that exercise can induce mitochondrial biogenesis in a wide range of tissues not normally associated with the metabolic demands of exercise. Perturbations ...

We hypothesized that the information obtained from a discriminant analysis could be used to objectively discriminate horses untrained from early ages, in agreement with certain physiological characteristics. In the biopsies of 24 Spanish Pure Bred horses (1.5-3years old) before and after a standardized exercise test (SET; 4-7m/s with a change ...

PURPOSE:: Energy expenditure measured in METs (metabolic equivalents) is widely used in cardiovascular medicine, exercise physiology and nutrition assessment. However, measurement of METs requires complex equipment to determine oxygen consumption. A simple method to predict oxygen consumption based on heart rate (HR) measurements without requirement for gas analysis, movement recording ...

Early adolescence is developmental period when youth begin to shift exercise and physical activity patterns toward increased sedentary living. The major causes and contributing factors to this change are poorly understood. This study examines the relationship between sociodemographic factors, behavioral and family factors that influence physical activity patterns of middle ...

Carbohydrate (CHO) and caffeine (CAF) both improve endurance performance. To determine by systematic literature review coupled with meta-analysis whether CAF ingested with CHO (CHO+CAF) improves endurance performance more than CHO alone. Databases were searched using the keywords caffeine, endurance, exercise, carbohydrate, and performance. Criteria for inclusion were studies that used ...

Liposuction is the most popular aesthetic surgery performed in Brazil and worldwide. Evidence showing that adipose tissue is a metabolically active tissue has led to the suggestion that liposuction could be a viable method for improving metabolic profile through the immediate loss of adipose tissue. However, the immediate liposuction-induced increase ...

The erythrocyte is proposed to play a key role in the control of local tissue perfusion via three O(2)-dependent signaling mechanisms: 1) reduction of circulating nitrite to vasoactive NO, 2) S-nitrosohemoglobin (SNO-Hb)-dependent vasodilatation, and 3) release of the vasodilator and sympatholytic ATP; however, their relative roles in vivo remain unclear. ...

Alterations of blood rheology related to muscular activity have been extensively studied over the last 20 years. It has been shown that exercise exerts a "triphasic" action on the rheological properties of blood. In the short term, exercise induces a transient hyperviscosity, mostly due to a rise in hematocrit and ...

BACKGROUND: Tissue Viability Imaging (TiVi) is an emerging bioengineering technology intended for two-dimensional mapping of skin erythema and blanching. Before TiVi can be effectively used in studies of diseased or damaged skin, the variability in normal skin red blood cell concentration (RBC(conc)) requires evaluation. OBJECTIVE: To demonstrate how TiVi maps ...

The O(2) transport from mixtures of commercially produced hemoglobin-based O(2) carriers (HBOCs) and red blood cells (RBCs) flowing through arteriolar-sized (25-mum) conduits is simulated. A generalized treatment of extraluminal O(2) transport processes is used to reflect variations in physiological conditions, such as increased O(2) consumption. Of the HBOCs considered, polymerized ...

BACKGROUND: The activation marker CD40 ligand (CD40L) has recently been demonstrated to be released from the cytoplasm of platelets (PLTs) during storage. CD40L may be associated with some adverse transfusion reactions including febrile responses and transfusion-related acute lung injury. CD62P has been traditionally measured to assess PLT activation. This study ...

Activation of the NO/cGMP pathway modulates smooth muscle cells relaxation and hence vasoconstriction, a major hindrance for the use of cell-free haemoglobin (Hb) as blood substitute, despite conjugation with 5-kDa maleimide poly(ethylene)-glycol (PEG) reduces vasoconstriction in vivo. We aimed at assessing how a recently developed PEGylated-Hb (Deoxy-PEGHb) and manipulation of ...

At present, the relative severity of the bleeding in exercise-induced pulmonary hemorrhage (EIPH) is better evaluated using scoring methods based on tracheobronchoscopic assessment of bleeding or red blood cells (RBCs) count in broncho-alveolar lavage (BAL). However, misinterpretation might happen with tracheobronchoscopic examination when the hemorrhage is tiny as well as ...

The present study examines the relationship between the bulk tank somatic cell count (SCC) mean and sigma (an estimate of variation) and the probability of exceeding a SCC standard. Daily or every other day, bulk tank SCC data were collected for 24 mo from 1,501 herds. Mean and sigma were ...

Recent studies suggest that overexpression of the polyamine-acetylating enzyme spermidine/spermine N(1)-acetyltransferase (SSAT) significantly increases metabolic flux through the polyamine pathway. The concept derives from the observation that SSAT-induced acetylation of polyamines gives rise to a compensatory increase in biosynthesis and presumably to increased flow through the pathway. Despite the strength ...

Intracellular/extracellular lactate (Lac) distribution has been determined before in human and animal erythrocytes (red blood cells [RBCs]) with various methods. However, all previous methods determine intra- and extracellular Lac separately or indirectly. Now, (13)C-NMR spectroscopy has been used to monitor intra- and extracellular Lac simultaneously in intact RBCs. Isolated human ...

Colonization by Bordetella bronchiseptica results in a variety of inflammatory respiratory infections, including canine kennel cough, porcine atrophic rhinitis, and a whooping cough-like disease in humans. For successful colonization, B. bronchiseptica must acquire iron (Fe) from the infected host. A vast amount of Fe within the host is sequestered within ...

Restricted Item. Print thesis available in the University of Auckland Library or available through Inter-Library Loan. Stress responses to exercise were compared for two tropical teleosts. The sweetlip emperor (Lethrinus chrysostomus), a relatively active species, increased plasma catecholamines after 1 min exercise. Exhaustive exercise increased hematocrit (Hct) and hemoglobin (Hb) ...
