Oxidative stress arises from an imbalance between reactive species (RS) production and the antioxidant defense, increasing the brain susceptibility to neurodegenerative and psychiatric diseases. Besides, changes in the expression or activity of neurotransmitter metabolism enzymes, such as monoamine oxidases (MAO), are also associated with mental disorders, including depression. Considering this, antioxidant and MAO-A activity inhibitory potential of six 2,3-chalcogenodihydrobenzofurans (2,3-DHBF) was investigated through in vitro and in silico tests.

Recently, CA IX and CA XII have been studied for their role in cancer diseases, motivating the design of inhibitors of these isoforms.
Material And Method: Here, we used the tail approach to design a new series of monoaryl () and bicyclic () benzensulfonamide derivatives CA IX and CA XII inhibitors.

Hypophosphatemic rickets is a rare bone disease characterized by short stature, bone deformities, impaired bone mineralization, and dental problems. Most commonly, hypophosphatemic rickets is caused by pathogenic variants in the X-chromosomal gene, but autosomal dominant and recessive forms also exist. We investigated a Finnish family in which the son (index, 29 yr) and mother (56 yr) had hypophosphatemia since childhood.

Design and reliability assessments of the AUS are typically performed using a clinical approach, which does not provide data on mechanical stimulation of urethral tissues. Mechanical stimulation may determine tissue degeneration, such as urethral atrophy or erosion, the main causes of AUS failure.

Background And Purpose: Understanding the cellular and molecular effect of proton radiation, particularly the increased DNA damage complexity at the distal end of the Bragg curve, is current topic of investigation. This work aims to study clonogenic survival and DNA damage foci kinetics of a head and neck squamous cell carcinoma cell line at various positions along a double passively scattered Bragg curve. Complementary studies are conducted to gain insights into the link between cell survival variations, experimentally yielded foci and the number and complexity of double strand breaks (DSBs).
