Isotopic compositions of reactants affect the rates of chemical and biochemical reactions. Usually it is assumed that heavy stable isotope enrichment leads to progressively slower reactions. Yet the effect of stable isotopes may be nonlinear, as exemplified by the "isotopic resonance" phenomenon. Since the isotopic compositions of other planets of Solar system, including Mars and Venus, are mar...

Background. There is to our knowledge metabolic changes induced by combined oral contraceptives (COC) use in regularly active females. Objectives. Analyzing blood cortisol and other biochemical variables in active (COC) users and non-users. Methods. A total of 123 active female students (25 COC users and 98 non-users) volunteered to participate in the study.  The COC users declared 2-3 years ...

Nutritional status should be assessed at regular intervals as part of management of human immunodeficiency virus (HIV) infection. The simplest approach to assessment is serial weight measurement. A comprehensive nutritional assessment includes (1) anthropometric measurements of body composition; (2) biochemical measurements of serum protein, micronutrients, and metabolic parameters; (3) clinica...

background: the present study was conducted to investigate the possible effects of l-carnitine and glutamine and their synergistic effects on male soccer athletes. methods: 28 male soccer players (21.1±0.7 y) were enrolled in a randomized pre and post intervention, double-blind design. before the intervention, their performances were assessed by bruce protocol, and their body composition was me...

the purpose of this study was to investigate the effect of one-month fasting along with yoga training on the body composition of novice female athletes. twenty trained women were randomly assigned to experimental (n=10) and control (n=10) groups. the experimental group participated in yoga training classes for 4 weeks, two 60-min sessions per week; the control group did not participate in any r...

the application of nanotechnology in drug delivery and a variety of supplements is very impressive. in this regard, the use of this knowledge can be effective in the performance of medicinal plants in aquaculture. in the present study aloe vera was extracted and its nanoparticles were produced. three levels of aloe vera nanoparticles in siberian sturgeon (acipenser baerii) were evaluated for th...

BACKGROUND & OBJECTIVES Certain antiepileptic drugs (AEDs) such as valproic acid (VPA) are known to affect body weight, and lipid profile. However, evidences regarding effects of AEDs on the body composition are deficient. This cross-sectional study compared the body composition and lipid profile among patients with epilepsy on newer and conventional AEDs. METHODS The patients with epilepsy (...
