Objective: To determine the effect of electroacupuncture (EA) on β-adrenergic receptor (β-AR) and post-receptor protein kinase A (PKA) signaling pathway after acute myocardial ischemia (MI).
Methods: An MI model was established by ligating the left anterior descending coronary artery of wild-type (WT) C57/BL and β-AR mice (heterozygous for β-AR gene deletion). EA treatment was administered at HT5-HT7 or LU9-LU8.

(immortelle) essential oil is one of the most popular essential oils worldwide and it has many beneficial properties, including antimicrobial. However, in this plant, the chemical diversity of the essential oil is very pronounced. The aim of this work was to process the GC-MS results of four samples of essential oil of Serbian origin by chemometric tools, and evaluate the antimicrobial activity in vitro and in silico.

Mavacamten (Camzyos®) is a myosin modulator which reduces the interactions between myosin and actin. These are overly activated in hypertrophic cardiomyopathy (HCM), a source of exaggerated ventricular contractility, energy loss, and impairment of diastolic function (relaxation). The Food and Drug Administration (FDA) and the European Medication Agency (EMA) approved mavacamten for the treatment of symptomatic obstructive HCM (NYHA class II or III) in adult patients in 2022 and 2023, respectively.

During pregnancy, the uterus undergoes several modifications under the influence of hormonal and mechanical stimuli. We hypothesize that while most of these modifications are reverted during involution, some of the physiological properties of the uterus are permanently altered. To investigate this hypothesis, we conducted motility experiments to evaluate the contractility response of uterine tissue samples from non-pregnant virgin and proven breeder female rats to oxytocin (10 to 10 M).
