Sex-specific alterations in creatine metabolism in cellular compartments of peripheral blood leukocytes in type 1 diabetes

AIMS Bioengineering
The creatine (Cr)/creatine kinase (CK) system plays a crucial role in cellular energy metabolism, glucose control, and the immune response. This study aimed to investigate this system in the peripheral blood leukocytes (PBL) of Armenians with type 1 ...

β‐Hydroxy β‐Methyl Butyric Acid (HMB) and Its Potential Doping Relevance: A Pilot Study on Its Urinary Excretion Profile

Drug Testing and Analysis, EarlyView.
β‐hydroxy β‐methyl butyric acid (HMB), either as the free acid or in the form of its calcium salt, is a component of several dietary supplements marketed to enhance sports performance. We investigated the urinary excretion profile of HMB, also assessing the endogenous reference ranges of HMB in human urine samples from healthy volunteers (n = 20). Data

UHPLC‐QTOFMS Urine Drug Screening With Dilute‐and‐Shoot Sample Preparation and Vacuum‐Insulated Probe‐Heated Electrospray Ionization

Drug Testing and Analysis, EarlyView.
The new ionization technique, vacuum‐insulated probe‐heated electrospray, allows for a simple dilute‐and‐shoot sample preparation to be used with liquid chromatography time‐of‐flight mass spectrometry in urine drug screening. Comparison with a method relying on solid‐phase extraction and conventional electrospray ionization shows improved performance ...

Sports Supplement Analysis Survey for the Prevalence of WADA Prohibited Substances in the Australian Online Marketplace

Drug Testing and Analysis, EarlyView.
A survey of 200 sports supplements purchased online in Australia and analysed for WADA Prohibited Substances. Athlete education regarding the use of sports supplements remains a high priority as 35% of the products contained WADA Prohibited Substances. ABSTRACT Sports supplements are used extensively by people involved in competitive sports. However, a
