A session of low-frequency electroacupuncture (EAP) of the nerve points of the cervicobrachial or lumbosacral regions was performed in 61 patients with vertebral osteochondrosis. An EAP therapeutic effect, analgetic one in particular, was found to depend on cortisol and aldosterone blood levels: reduced levels of the hormones related to EAP procedure appeared associated with a positive therapeutic response.

Technetium-99m plays a pivotal role in nuclear medicine, offering unique IMAGING capabilities due to its favorable physical and chemical properties. This study investigates the redox behavior and electronic structures of three representative Tc(V) oxo complexes, [TcO(HMPAO)], [TcO(Bicisate)], and [TcO(DMSA)], using computational techniques. Employing relativistic density functional theory with the Zero-Order Regular Approximation (ZORA), we analyze singlet-triplet energy gaps, Gibbs free energy changes, and redox potentials in neutral and acidic environments.

Hyperpolarized-C magnetic resonance imaging (HP-C MRI) was used to image changes in C-lactate signal during a visual stimulus condition in comparison to an eyes-closed control condition. Whole-brain C-pyruvate, C-lactate and C-bicarbonate production was imaged in healthy volunteers (N = 6, ages 24-33) for the two conditions using two separate hyperpolarized C-pyruvate injections. BOLD-fMRI scans were used to delineate regions of functional activation.

Current metabolomics technologies can measure hundreds of chemical entities in tissue extracts with good reliability. However, long-recognized requirements to halt enzyme activities during the initial moments of sample preparation are usually overlooked, allowing marked postmortem shifts in levels of labile metabolites representing diverse pathways. In brain many such changes occur in a matter of seconds.

Oocyte maturation arrest (OMA) may occur at different stages, including the germinal vesicle (GV), metaphase I (MI), and metaphase II (MII). A total maturation arrest of human oocytes is rarely observed during fertilization (IVF). We have identified a case of infertile female for whom all oocytes fail to mature and are arrested at MI.

Objectives: Polycystic Ovary Syndrome (PCOS) is a complex condition affecting approximately 1 in 10 women of reproductive age. However, limited data are available regarding the specific characteristics and needs of women with PCOS in Latin America. This consensus sought to evaluate the evidence-based practices for the management of PCOS for Latin American populations, consolidate regional insights, identify eventual gaps in implementation and identify key research opportunities.
