Background: Dapagliflozin is an inhibitor of sodium-glucose co-transporter 2 (SGLT-2) in development for the treatment of Type 2 diabetes. To support toxicology studies, LC-MS/MS methods were developed and validated for the quantitation of dapagliflozin in rat plasma.
Results: The assay uses solid phase extraction and LC-MS/MS analysis in negative ion electrospray ionization mode. Because dapagliflozin readily forms adducts in the presence of formic acid, the mobile phases were simple mixtures of water and acetonitrile. The assay was validated in the concentration range of 5-2000 ng/ml with good intra- and inter-day precisions and acceptable sample stability.
Conclusion: The validated assay was successfully applied to the quantitation of dapagliflozin in plasma in support of preclinical studies in both normal and diabetic rats.

Background: Obesity is a rising risk factor for various diseases including cardiovascular diseases and Cancer. The limitations of targeted obesity-treatment approaches employed in the clinic presently underscore the importance of developing integrative management strategies for identification of specific biomarkers of obesity.
Objectives: Given the specificity of exosome/extracellular vesicle (EV) biomarkers, we aimed here to identify the EV biomarkers of Ayurveda treatment - Lekhana Basti - for Obesity.

Atherosclerosis is a major cause of morbidity and mortality worldwide; in Israel, ischemic heart disease is the second leading cause of death for both genders aged 45 and above. Atherosclerosis involves stiffening of the arteries due to the accumulation of lipids and oxidized lipids on the blood vessel walls, triggering the development of artery plaque. Coronary artery disease (CAD) is the most common manifestation of atherosclerosis.

Background: Research into oxidative stress, cancer, and natural products revealed promising avenues for therapeutic intervention. Natural products are considered potent pharmaceuticals in combating oxidative stress and its relationship with cancer.
Methods: This study was carried out to evaluate the chemical profile and antioxidant activities using DPPH, ABTS, Phenanthroline, Cupric, Phosphomolybdenum, FRAP, Hydroxyl, Iron chelation in vitro assays, and anticancer properties by MTT method of Cistus creticus extracts.

This study employed QuEChERS extraction method combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS) to analyse honey samples from Albania for nitroimidazole residues. This approach allowed for the detection of trace-level residues, achieving sensitivity in the parts per billion range. Out of the 45 honey samples analysed, 6 exceeded the European Union's safety limit of 1 µg/kg, with metronidazole (MNZ) and dimetridazole (DMZ) being the predominant contaminants.

Several decades have passed since the description of the first patient with primary aldosteronism (PA). PA was initially classified in two main forms: aldosterone-producing adenoma (APA) and idiopathic hyperaldosteronism (IHA). However, the pathogenesis of PA has now been shown to be far more complex.
