Long-term preservation of gametes has been identified as a tool to improve broodstock management and increase the number of juveniles produced by artificial fertilization. Paralichthys orbignyanus is an important commercial and recreational species distributed in marine and estuarine waters from Rio de Janeiro (Brazil) to the San Matías Gulf (Argentina). This work focused on studying the seminal quality of tank-reared P.

Abstract: Sperm capacitation is a necessary process for mammalian spermatozoa to acquire fertilization capability.
Overweight and obesity may cause a reduced response to vaccination. The purpose of the present research was to study the relationship between current body mass index (BMI) and antibody persistence after vaccination against measles, mumps, and rubella (MMR) and hepatitis B virus (HBV) given during childhood, as per the current vaccination schedule. The study was conducted on 2185 students at the School of Medicine, University of Padua, Italy.

- - The World Health Organization defines health as a comprehensive state of well-being, emphasizing the need for a biopsychosocial approach in managing health conditions.
- - The review analyzes 20 articles on the biological, psychological, and social impacts of porphyrias, a group of rare metabolic disorders that affect heme production, particularly focusing on different types like Acute Hepatic Porphyrias, Porphyria Cutanea Tarda, and Erythropoietic Protoporphyria.
- - Findings suggest that using questionnaires primarily addresses quantitative aspects, while direct interviews with psychology professionals yield richer qualitative insights; a combination of both methods is recommended for effective management of these disorders.
Article Synopsis
- Sperm capacitation is essential for fertilization in mammals, and decapacitation factors (DFs) like SPINK3 inhibit premature capacitation.
- SPINK3 binds to the sperm membrane through specific lipid interactions, particularly in lipid rafts, and its binding can be blocked by cholera toxin subunit B (CTB).
- During the capacitation process, SPINK3 is gradually removed from sperm in the female reproductive tract, starting from the sperm's head and then from its tail, correlating with the presence of acrosome-reacted sperm when SPINK3 is absent.
