Lumbar bone mass (LBM) determination by quantitative computerized tomography in pre-, peri- and postmenopausal women was utilized to identify subjects at risk to develop osteoporosis. The results were related to determinations of bone metabolic markers (serum osteocalcin and urinary calcium excretion). Osteocalcin was the only metabolic marker which underwent significative changes. However, we found very poor correlations between LBM and metabolic markers and it is concluded that bone mass determination remains the method of choice to select women for preventive therapy.

Previous research has highlighted the critical role of amino acid metabolism (AAM) in the pathophysiology of sepsis. The present study aimed to explore the potential diagnostic and prognostic value of AAM-related genes (AAMGs) in sepsis, as well as their underlying molecular mechanisms. Gene expression profiles from the Gene Expression Omnibus (GSE65682, GSE185263 and GSE154918 datasets) were analyzed.

Extracellular vesicles (EVs) are carriers of a diverse array of bioactive molecules, making them valuable clinical tools for liquid biopsy in disease diagnosis and prognosis evaluation. These molecules play critical roles in various physiological and pathological conditions, and effective separation of EVs is essential to achieve these objectives. Due to the high heterogeneity of EVs, particularly with regard to their cargo molecules, merely isolating the general EV population is inadequate for liquid biopsy and biological function studies.

Introduction: The grayling ( L.) has several advantages over other fish species that make it attractive for aquaculture and invest it with importance for food security. The study assessed the effects of a β-glucan-enriched diet on biomarkers of oxidative stress, energy metabolism and lysosomal function in muscle tissue of European grayling ( L.

Despite a high sucrose accumulation in its taproot vacuoles, sugar beet (Beta vulgaris subsp. vulgaris) is sensitive to freezing. Earlier, a taproot-specific accumulation of raffinose was shown to have beneficial effects on the freezing tolerance of the plant.

Background: Neurovascular coupling (NVC) refers to the process of aligning cerebral blood flow with neuronal metabolic demand. This study explores the potential of contralateral NVC-linking neural electrical activity on the stroke side with cerebral blood flow velocity (CBFV) on the contralesional side-as a marker of physiological function of the brain. Our aim was to examine the association between contralateral NVC and neurological outcomes in patients with ischemic stroke following endovascular thrombectomy.
