The effect of l-arginine on liver function in SCD has received little or no attention. The effect of a chronic, oral, low-dose supplementation with l-arginine (1gm/day for 6 weeks) on some liver enzymes, lipid peroxidation and nitric oxide metabolites was studied in 20 normal (non-sickle cell anaemia; NSCA) subjects and 20 sickle cell anaemia (SCA) subjects. Ten milliliters of blood was withdrawn from an ante-cubital vein for the estimation of plasma arginine concentration ([R]), alanine aminotransaminase (ALT), aspartate aminotransaminase (AST) and alkaline phosphatase (ALP), plasma total bilirubin concentration [TB], malondialdehyde concentration [MDA] and nitric oxide metabolites concentration [NOx]...

National Strength and Conditioning Association position statement on long-term athletic development. J Strength Cond Res 30(6): 1491-1509, 2016-There has recently been a growing interest in long-term athletic development for youth. Because of their unique physical, psychological, and social differences, children and adolescents should engage in appropriately prescribed exercise programs that promote physical development to prevent injury and enhance fitness behaviors that can be retained later in life...

Intrinsic sensory neurons (ISNs) of the enteric nervous system respond to stimuli such as muscle tension, muscle length, distortion of the mucosa, and the chemical content in the lumen. ISNs form recurrent networks that probably drive many intestinal motor patterns and reflexes. ISNs express a large number of voltage- and calcium-gated ion channels, some of which are modified by inflammation or repeated physiological stimuli, but how interactions between different ionic currents in ISNs produce both normal and pathological behaviors in the intestine remains unclear...

BACKGROUND: There is a known association between congenital heart disease (CHD) and other congenital anomalies (CA). These associations have been altered by changes in prenatal factors in recent time. We reviewed the largest database of inpatient hospitalization information and analyzed the current association between common CHD diagnoses and other congenital anomalies. MATERIALS AND METHODS: Case-control study design. We reviewed the Nationwide Inpatient Sample (NIS) database from 1998 to 2008 and identified all live births with CHD diagnosis (case) and live births without CHD diagnosis (control)...

Pressor and heart rate changes following change in posture without or with L-arginine supplementation (1g/day for 6 weeks) were studied in 28 sickle cell anemia (SCA) and 32 non-sickle cell anemia (NSCA) subjects. Change in posture increased HR (p<0.01), RPP (p<0.05) in both groups of subjects, MABP (p<0.05) in SCAS but reduced MABP (p<0.01) in NSCAS and PP (p<0.01) in SCAS. L-Arginine supplementation increased plasma L-Arginine concentration ([R]) in both groups of subjects (p<0.001 in each group) and serum nitric oxide metabolites concentration ([NOx]) (p<0...

Compared to proprioceptive afferent collateral projections, less is known about the anatomical, neurochemical, and functional basis of nociceptive collateral projections modulating lumbar central pattern generators (CPG). Quick response times are critical to ensure rapid escape from aversive stimuli. Furthermore, sensitization of nociceptive afferent pathways can contribute to a pathological activation of motor circuits. We investigated the extent and role of collaterals of capsaicin-sensitive nociceptive sacrocaudal afferent (nSCA) nerves that directly ascend several spinal segments in Lissauer's tract and the dorsal column and regulate motor activity...

Cell-penetrating peptides (CPPs) are attractive vectors for in vivo and in vitro cellular uptake. Their use is, however, limited by insufficient understanding of their preference for a target cell. Here, a new CPP screening method is presented that uses mRNA display. After incubating the target cell lines, such as human embryonic kidney 293 (HEK 293) and HeLa cells, with an mRNA display library for 3 h at 37°C, the CPP-mRNA nucleotide conjugates were harvested. These were amplified with PCR and subsequently sequenced...

BACKGROUND: Trace elements are required for the performance of numerous functions of immune cells. It is not clear whether levels of trace elements are elevated and whether there is a relationship between the levels of liver enzymes and trace elements in patients with sickle cell anaemia in crisis. OBJECTIVE: To compare the plasma levels of liver enzymes and trace elements in non sickle cell anaemia (NSCA), sickle cell anaemia subjects in the steady state (SCASS) and sickle cell anaemia patients in crisis (SCAC)...

Autonomic function following change in posture with or without vitamin C supplementation was studied in ten (10) sickle cell anemia (SCA) and twelve (12) non-sickle cell anemia (NSCA) subjects. Arterial blood pressure and electrocardiographic measurements were taken in the supine position on a couch 80cm high and immediately on assumption of the upright position. Vitamin C was then administered orally (300mg/day for 6 weeks). At the end of the period, blood pressure and ECG measurements were again made in the supine position and in response to change in posture...

Both industrial and municipal firefighters need to maintain high levels of physical fitness and minimize cardiovascular risk factors. The nature of firefighter responsibilities in industrial and municipal settings may vary, affecting the ability to sustain high levels of physical fitness. We compared the working conditions, physical fitness, and exercise training practices of an industrial fire department (n = 17) to those of a nearby municipal fire department (n = 55). After informed consent, aerobic capacity, muscular strength, muscular endurance, body composition, flexibility, blood lipid concentrations, and blood pressure levels were measured...

The Education Recognition Program (ERP) was developed to acknowledge academic institutions meeting departmental criteria established by the National Strength and Conditioning Association (NSCA) for having an area of concentration in undergraduate strength and conditioning. Since its inception, over 40 universities have received recognition status. The NSCA is currently examining the interest, need, and feasibility of creating an ERP for graduate curriculum specific to sports performance. The current investigation included a survey of Division I, II, and III strength and conditioning professionals...

Sulfate-containing aerosol (SCA) dry deposition at the highway intersection, coastal location, and suburban area in Taiwan were analyzed and compared. Sampling was accomplished with a surrogate surface technique. Samples particles were coated with barium chloride (BaCl(2)) in a vacuum evaporator and then exposed to a relative humidity of 85% for 2 h to form distinctive products of SCAs. Treated samples were examined by a scanning electron microscopy. SCA dry deposition fluxes were 10.2, 4.1, 3.4 microgm(-2)s(-1) and nonsulfate-containing aerosol (NSCA) dry deposition fluxes were 23...

Undergraduate exercise science programs develop curricula by referring to standards set by professional organizations. A web-based survey was administered to 235 institutions with exercise science undergraduate programs to evaluate their adherence to stated curricular guidelines. Results indicate that 29% of institutions considered American College of Sports Medicine (ACSM) Knowledge, skills, and abilities (KSAs); 33% both ACSM and National Association for Sport and Physical Education (NASPE) guidelines; 6% ACSM, NASPE, and National Strength and Conditioning Association (NSCA); 8% ACSM, NASPE, NSCA, and American Society of Exercise Physiologists, and 5% NASPE...

The effects of warmth stimulation and/or supplementation with vitamin E (300 mg/day for 6 weeks) on forearm blood flow (FBF) and forearm vascular resistance (FVR) were measured in 8 sickle cell anaemia (SCA) (mean age = 22.8 + 0.8 years) and 11 non sickle cell anaemia (NSCA) subjects (mean age = 23.2 + 1.1 years) of both sexes. Warmth stimulation was induced by immersing the left foot in warm water at 400C for 2 minutes. Forearm blood flow was measured with the venous occlusion plethysmography method. Warmth increased FBF (p <0...

1. The effects of englitazone sodium, an antidiabetic agent, on ion channel activity in the CRI-G1 insulin secreting cell line was examined by use of the patch clamp technique. 2. Application of englitazone to the outside of CRI-G1 cells in the whole-cell recording configuration produced concentration-dependent inhibition of KATP currents with an IC50 value of 8 microM. The inhibition of the K+ current was not affected by the removal of Mg2+ ions from or the addition of trypsin to the solution bathing the intracellular surface of the cell membrane...
