AIM To analyze detailed changes in hematology and biochemistry tests parameters before and after a long-distance race in ultramarathon runners. METHODS Blood samples of 11 participants were obtained for standard analysis before, immediately after, two days after and nine days after the 2002 International Ultra-marathon 24 h Race and the International(More)
BACKGROUND The change of anaerobic exercise abilities during and after a high-altitude expedition or hypoxic exposure is not well studied. To evaluate the effects of an extreme-altitude expedition on anaerobic performance, the 10-second supramaximal test and endocrine hormones were evaluated before and after an expedition to Peak Lenin. METHODS Four(More)
AIM To assess the effects of L-arginine (L-Arg) supplementation on pulmonary oxidative stress and antioxidant defenses in rats after exhaustive exercise. METHODS Rats were randomly divided into four groups: sedentary control (SC), sedentary control with L-Arg treatment (SC+Arg), exhaustive exercise with control diet (E) and exhaustive exercise with L-Arg(More)
The Lanyu pig is an indigenous miniature pig breed on Lanyu Islet near Taiwan, with a mitochondrial DNA genetic lineage remote from Asian and European pig breeds. The unknown population genetic structure and increased inbreeding among the small population of conserved Lanyu pigs is now of great conservation concern. Additionally, the presence for more than(More)
AIM This study investigated the effects of intense training on lipid metabolism, bone metabolism and bone mineral density (BMD) in female athletes. METHODS Sixty-six female subjects participated in this study, age ranging from 18 to 55 years. The sample group included thirty-six athletic subjects and the control group comprised thirty non-athletic(More)
AIM To study the effect of Huangqi Jianzhong Tang in reducing fatigue improvement in athletes. METHODS Twelve athletes were randomly separated into a control group, whose members were administered with placebos, and the experimental group, whose members were administered with Huangqi Jianzhong Tang. During the eight weeks of the experiment, test subjects(More)
Novel tricyclic Ras farnesyl-protein transferase (FPT) inhibitors are described. A comprehensive structure-activity relationship (SAR) study of compounds arising from substitution at the 3-position of the tricyclic pyridine ring system has been explored. In the case of halogens, the chloro, bromo, and iodo analogues 19, 22, and 28 were found to be(More)
The antimicrobial properties of chitosan, a derivative of chitin, were investigated in the solid and liquid culture against bacteria associated with waterborne disease in order to assess the potential for using chitosan as a natural disinfectant. Six strains which included three gram-negative and three gram-positive bacteria were studied. The effects of the(More)
