Athletes and Performance- Enhancing Drugs Performance- enhancing drugs are pharmaceutical products or illegal drugs that are used by sports people to gain a competitive advantage over those who do not use them. Performance enhancing drugs commonly used include anabolic androgenic steroids, testosterone, human growth hormone, erythropoietin and other androgens (Grace & Baker, 2012). These drugs for example anabolic androgenic steroids imitate the activity of natural testosterone and lead to fast…

focuses on delineating animal 's metabolic responses to nutrition interventions or health conditions, associated with the animal performance and quality of its derived products. I use a combination of modern analytical chemistry (liquid/gas chromatography and mass spectrometry) and bioinformatics (univariate and multivariate statistical analysis) to measure metabolites in biological samples to provide insights on physiological or pathological status and nutrition effects. More specifically, I am…

their latest paper, published in Elsevier’s Journal of Chromatography B, Professor Olof Beck and his team have successfully developed the first fully validated and robust screening method suitable for the routine measurement of drugs of abuse in exhaled breath, with a simple procedure for specimen collection sample preparation. This was followed by a highly sensitive analytical technique known as LC-MS (Liquid chromatography–mass spectrometry). The drugs of abuse identified include:…

The column was Rtx-5 capillary columns (60 m ´ 0.32 mm, 0.25 μm film thickness). Helium (He) was the carrier gas at a flow rate 1.0 mL/min. The GC was interfaced with (Perkin Elmer Clarus 500) mass detector operating in the EI+ mode. The mass spectra were recorded over 40-500 amu that revealed the total ion current (TIC) chromatograms, using an ionizing voltage of 70 eV. Temperature program was used as the same as described above for GC analyses. The temperatures of…

Chapter: Soil, Water and Air Pollution 1. Introduction: Definitions of soil, water and air pollution; sources and types of soil, water and air pollution, soil and water pollution status in India With rapid increase and development in industrial and agricultural sectors along with population explosion, huge amount of organic and inorganic waste is released in environment and causing serious threats to environment and agro-ecosystem. This procedure can bring about a danger in the human wellbeing.…

Salmonella infection in food is the one of the major causes of foodborne illnesses including fever, abdominal pain, diarrhea, and nausea. Thus, early detection of Salmonella contamination is important for our healthy life. Conventional detection methods for the food contamination have limitations in sensitivity and rapidity, thus the early phase detection has been difficult. Herein, we developed a bioelectronic nose using a carbon nanotube (CNT) field-effect transistor (FET) functionalized with…
