Heart tissue injury may release cardiac enzymes into the circulation and elevate serum enzyme levels (LaDue, Wroblewski, and Karmen, 1954). Many enzymes become raised, but three enzymesaspartate aminotransferase (EC 2.6.1.1), creatine kinase (EC 2.7.3.2), and lactate dehydrogenase (EC 1.1.1.27)-have proved of particular diagnostic value. In addition, determination of lactate dehydrogenase isoen...

the rapid advancement of nanotechnology enables us to use nanoscale particles. this material in terms of physical, chemical and biological characteristics are unique compared to larger particles. increased cell division, apoptosis, oxidative stress has been associated with toxic effects of nano-silver. the aim of this study was to evaluate histipotological changes and enzyme activity in nanopar...

despite recent innovations in the laboratory diagnosis of bacterial from nonbacterial meningitis, solid data-necessary for early determination of bacterial meningitis (bm) before organism growth in the culture medium-are missing. therefore cerebrospinal fluid (csf) lactate levels were evaluated as a possible means of differentiating the two clinical entities. this was a retrospective study. pat...

introduction: the use of antioxidants before high-intensity training, which leads to the release of free radicals and muscle injuries, can result in reduced damage during exercise. accordingly, in this study, we aimed to evaluate the effect of selenium supplement intake on oxidative stress, following exhaustive aerobic exercise among young physically-active females. methods: in this quasi-exper...

aloe vera is a medicinal plant as antioxidants reduce cell damage and used. the purpose of this study was to determine the effect of aloe vera on lactate de-hydrogenase after a period of aerobic exercise in male athletes.methods this study applied the method according to the nature of the study, based on semi-empirical research and a review of the pre-test, post-test supplements and placebo gro...

objective(s): carbon nanotubes have unique mechanical, electrical, and thermal properties, with potential different applications in nanomedicine, electronics, and other industries. these new applications of carbon nanotubes in different industries lead to the increased exposure risk of nanomaterials to human. up to now, all aspects of carbon nanotubes toxicity are not completely clear following...
