In Vitro Inhibition of Human Sperm Creatine Kinase by Nicotine, Cotinine and Cadmium, as a Mechanism in Smoker Men Infertility

Background Nicotine, cotinine and cadmium are harmful components of cigarettes that have an effect on human reproductive function. Although the effects of cigarette smoke on male reproductive function is characterized in several articles its mechanism of action is still unknown. In the present study, we investigate the effect of nicotine, cotinine and cadmium on human sperm creatine kinase acti...

The Effect of Cigarette Smoking on Human Sperm Creatine Kinase Activity: As An ATP Buffering System in Sperm

Comparison of Effect of Piperine and Capsaicin with Tabata Exercise on Changes in Serum Nitric Oxide and Creatine Kinase of Kung Fu Boys

Introduction: Tabata exercise programs can produce free radicals and muscle soreness and herbal supplements may be helpful as mediators in response to oxidative damage and muscle stress. Therefore, the purpose of this study was to compare the effects of these two supplements with Tabata exercise activity on nitric oxide and creatine kinase enzyme. Methods: The research was a quasi-experimental...

In vitro Effect of Lead, Silver, Tin, Mercury, Indium and Bismuth on Human Sperm Creatine Kinase Activity: a Presumable Mechanism for Men Infertility

Background: The aim of the present study was to investigate the in vitro effects of mercury (Hg+2), lead (Pb+2), silver (Ag+2), tin (Sn+2), bismuth (Bi+3) and indium (In+3) ions on sperm creatine kinase. Methods: creatine kinase was isolated from human sperm homogenates after chromatography on a DEAE cellulose column. Results: At 60 µg ml-1 metal concentration, 70% of the creatine kinase activi...

Levels of C-reactive protein, creatine kinase-muscle and aldolase A are suitable biomarkers to detect the risk factors for osteoarthritic disorders: A novel diagnostic protocol

Background: C-reactive protein (CRP), creatine kinase-muscle (CK-MM) and aldolase A (AldoA) levels are predicted to be realistic biomarkers of osteoarthritic disorders (OADs). The objective of the study was to evaluate the levels of CRP, CK-MM, and AldoA and determine their correlations with risk factors such as inflammation, muscle degeneration, and skeletal muscle damage for OADs. Methods: B...

The Effect of Active Recovery Time on Creatine kinase, Lactate dehydrogenase Changes in Response to One Session High Intensity Intermittent Exercise in Female Swimmers

Introduction and purpose: The aim of this study is effect of active recovery time on creatine kinase and lactate dehydrogenase changes in response to one session high intensity intermittent exercise in female swimmers. Materials and Methods: In this quasi-experimental study, 10 female swimmers with an age range of 20 to 26 years were placed in two experimental groups 1 (10 people) and experime...
