Use of performance-enhancing drugs concern not only elite Olympic and Paralympic Games' athletes but also amateur athletes, who are making increasing use of substances and/or methods. Furthermore, a new frontier reached by the doping is the use of genes. World Anti- Doping Agency (WADA), expressly prohibited the participation in competitive sports by the athlete in case of taking banned substances to treat disease in the event that the above assumption implies an excessive improvement of performance. This study aims to analyze and show the doping control as an essential part of the anti-doping program to promote and protect the integrity of sport and athlete's health...

AIM: The aim of this study was to investigate the effects on fitness indicators and subjective health-perception of a multimodal exercise programme provided by a district in Budapest among community-living seniors. METHODS: Sixty community-living older adults aged over 60 years formed beginner group (who were at the beginning of the exercise programme), advanced group (who had been in the programme for 3-6 months), active group (who had been participating in the exercise programme for at least 6 months, in addition to Nordic Walking programme) and a physically inactive control group...

BACKGROUND: Toe grip strength is the force of a toe on a surface. The objective of this study was to investigate the relationship between falls in middle-aged individuals and physical strength factors such as toe grip strength and knee extension strength. METHODS: The subjects were 194 middle-aged individuals (388 feet) who were independent in daily life, received no nursing care, and participated in a health sports event organized by a sports club. We evaluated the body composition, blood pressure, vascular age, systemic response, bone density, knee extension strength, and toe grip strength, and examined their relationship using a self-administered questionnaire survey...

The detection of antibiotics is critical and challenging due to the pervasive use of antibiotics had inevitably brought some negative impacts on ecosystem and human health. Herein, we reported an anti-interfere ability enhanced luminescent sensor of lanthanide metal-organic framework (Ln-MOF) filled mixed matrix membranes (MMMs), which combining the processibility of poly(methyl methacrylate) (PMMA) polymer with Ln-MOF of {[Tb2(AIP)2(H2O)10]·(AIP)·4H2O}n (Tb-AIP, where AIP is 5-aminoisophthalate) fillers...

Biopharmaceuticals have established themselves as highly efficient medicines, and are still one of the fastest growing parts of the health-product industry. Unfortunately, the introduction of these promising new drugs went hand in hand with the creation of a black market for illegal and counterfeit biotechnology drugs. Particularly popular are the lyophilised peptides with a molecular weight of less than 5kDa. Most of them are meant for subcutaneous injection and are easily accessible via the internet. In recent years, different methods based on reversed phase liquid chromatography have been developed to detect and quantify these peptides...

Meso-tetrakis(1,2-dimethylpyrazolium-4-yl)porphyrin sulfonate (TDMPzP), a water-soluble porphyrin derivative, was synthesized and used as a colorimetric reagent for Cu(2+) detection on a microfluidic paper-based analytical device (µPAD) using distance-based quantification. TDMPzP showed a high selectivity for Cu(2+) detection in aqueous solutions. When Cu(2+) was added to the TDMPzP under acidic conditions, a color change from green to a pink was observed by the naked eye. Under optimized conditions, the application of this system to a distance-based μPAD exhibited good analytical response...

Hepatitis A virus (HAV) infection has caused substantial morbidity and economic losses to human society, presenting a major public health problem in many parts of the world. Despite the capability for low-concentration detection, current PCR-based techniques are limited by the requirement of specialized lab equipment, trained personnel and a relatively large time-commitment. The need for a prompt in-field quantitative identification of HAV in real samples has led us to develop a chemiluminescent fibre optic genosensor system...

In this work, a miniaturized optical sensor was developed for fluoride determination in tea samples to evaluate their specific risks of fluorosis for public health based on evanescent-wave interaction. The sensor design was integrated on the optical fiber by utilizing the evanescent wave produced on the fiber surface to react with sensing reagents. According to the absorption change at 575nm, fluoride could be determined by colorimetric method and evaluated by Beer's law. With improved performances of small detection volume (1...

Amniotic fluid is the substantial factor in the development of an embryo and fetus due to the fact that water and solutes contained in it penetrate the fetal membranes in an hydrostatic and osmotic way as well as being swallowed by the fetus. Elemental composition of amniotic fluid influences the growth and health of the fetus, therefore, an analysis of amniotic fluid is important because the results would indicate abnormal levels of minerals or toxic elements. Inductively coupled plasma mass spectroscopy (ICP-MS) is often used for determination of trace and ultra-trace level elements in a wide range of matrices including biological samples because of its unique analytical capabilities...

The risk assessment code (RAC) is a common method for assessing heavy metal (HM) mobility and their potential health risks, based on HM total concentration and chemical speciation. In this study, both the RAC and the influence of ambient environmental factors were investigated in a river sediment system. Sixty-eight sediment samples were collected from the main river system in Shanghai, China. The total concentration and chemical speciation of Cu, Zn, Ni, Pb, Cd, Cr, As, and Hg were determined in the samples...

Cardiovascular complications induced by high fat are one of the most challenging health problems presently. Oxidative stress, inflammation and fibrosis are major components included in the pathology of diabetic cardiomyopathy. Nuclear factor erythroid 2-related factor 2 (Nrf2) has been reported as an essential therapeutic target in various diseases for its induction of anti-oxidant enzymes, and other protective enzymes. Additionally, a number of Nrf2 activators showed strong anti-inflammatory properties. In the study, we calculated the Nrf2-dependent anti-oxidant, anti-inflammatory and anti-fibrosis effects of chrysophanol in high fat diet-induced diabetic heart injury...

Surficial sediments were collected from 50 randomly selected Minnesota lakes, plus four a priori reference lakes, in 2007. The lakes encompassed broad geographic coverage of the state and included a variety of major land uses in the surrounding watersheds. Sediment samples were analyzed for a suite of metals, metalloids, persistent organic pollutants, total organic carbon, and particle size fractions. In addition, a small fish survey was conducted to assess PBDEs in both whole fish and fish tissues. Sediment quality in this set of lakes ranged from good (43%) to moderate (57%) based on an integrative measure of multiple contaminants...

Previous studies have demonstrated associations of perfluoroalkyl substances (PFASs), a group of highly persistent chemicals ubiquitous in wildlife and humans, with hypertension, but the relationships are mixed. Furthermore, academic literature on the relationship between isomers of PFASs and blood pressure (BP) and hypertension in populations from a higher pollution area is scant. We studied 1612 Chinese adults, ages 22-96years old, from Shenyang, China, utilizing high performance liquid chromatography-mass spectrometry to analyze isomers of perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), and other PFASs in blood serum...
