Chronic stress triggers impairments of the redox status of salivary glands associated with different histological responses in rats.

Stress occurs as a reaction to mental and emotional pressure, anxiety, or scarring. Chronic stress is defined as constant submission to these moments. It can affect several body systems, increase blood pressure, and weaken immunity, thereby interfering with physiological health processes.

Hormonal regulation and crosstalk during early endosperm and seed coat development.

This review covers the latest developments on the regulation of early seed development by phytohormones. The development of seeds in flowering plants starts with the fertilization of the maternal gametes by two paternal sperm cells. This leads to the formation of two products, embryo and endosperm, which are surrounded by a tissue of maternal sporophytic origin, called the seed coat.

Non-surgical endodontic retreatments in Brazil's public dental services: a 15-year nationwide register-based study.

The objective of this study was to analyze the provision of non-surgical endodontic retreatments in Brazil's public dental services from 2008 to 2022. A time series was outlined for this purpose. The annual numbers of non-surgical endodontic retreatments were retrieved from the Brazilian National Outpatient Information System and adjusted per 100,000 inhabitants to obtain the incidence between 2008 and 2022.

Pumpkin seed protein as a carrier for Astaxanthin: Molecular characterization of interactions and implications for stability.

This study investigated pumpkin seed protein (PSP) as a carrier for astaxanthin (AST). Interaction mechanisms revealed through fluorescence spectroscopy and molecular docking, showed that hydrogen bonds and Van der Waals forces form the PSP-AST complex. AST binding altered PSP's secondary structure, increasing α-helix (7.
