Introduction: Numerous studies have demonstrated that kisspeptin, a peptide from the KISS1 gene, plays an important role in regulating the secretion of gonadotropin releasing hormone (GnRH). Also, there is some evidence suggesting that kisspeptin can interact with other neuropeptides for the control of the reproductive axis. In the present study, we have investigated the effect of central admin...

DLLME, which is a method that minimizes organic solvent consumption and waste generation, frequently used for trace analyte determination. In the present work, simple, selective sentsitive spectrophotometric based on dispersive liquid-liquid microextraction was reported. The procedure formation of 1:1 complex between Fe3+ water-soluble Cu(II) phthalocyanine then extraction this into dichloromet...

In this work, we developed a method based on ultrasound-assisted emulsification microextraction (USAEME) for the determination of zinc and copper by flame atomic absorption spectrometry (FAAS). The method is based on the use of the organic solvent carbon tetrachloride (CCl4) as an extraction solvent. In order to obtain a high enrichment factor, the effect of different parameters affecting the c...

Human research has shown the administration of cortisol into the circulation at rest will result in reduced blood testosterone levels. Many researchers have used these results to imply that physical exercise induced cortisol increases would perhaps result in subsequent reductions in circulating testosterone levels. Our purpose was to examine this concept and determine what, if any, relationship...

In the work the results of the research aimed to determine the peculiarities of changes in the content of testosterone in the blood of people of different level of fitness under the influence of acute power load in the process of long trainings athleticism. The surveys were performed with the participation of 20 athletes age of 19-20 years, regularly engaged in athleticism over 3 years, and 20 ...

The aim of this study was to investigate the effects of three different duration (1, 3 or 5 min) rest intervals on hormonal response in 10x10 hurdle jumping series. Eleven adolescent male sprinters and jumpers (16.2±0.9 years, height 170.5±7.9 cm, body mass 70.9±11.1 kg, body mass index 22.0±3.4 kg/m2) participated in the study. An exercise session consisted of 10 two-legged jumps with arm swin...
