Rapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.ABSTRACT Rationale Distribution patterns of foraminifera are controlled by environmental parameters such as temperature, salinity, and nutrient concentrations in each water mass. Since trace elements to Ca ratios of marine microfossil calcite test of foraminifera record environmental and ecological habitat information, we used femtosecond (fs) LA‐ICP ...

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 2, Page 148-161, March 2026.ABSTRACT In fish, sex determination and gonadal development are controlled by various genetic and environmental factors. In this study, experiments were conducted on the estuarine mummichog (Fundulus heteroclitus) to investigate gonadal differentiation following exposure to the synthetic estrogen, 17α‐ethinylestradiol (EE2).

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.Equine endometrium can develop progressive fibrotic and functional alterations, probably correlated with age and inflammatory insults that alter uterine microenvironment, creating hostile conditions for embryo implantation. Named chronic degenerative endometritis, this condition leads to reduced fertility in older mares. Extracellular vesicles secreted

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.ABSTRACT Reproductive migration in anadromous fish involves complex physiological adjustments to support intense metabolic and reproductive demands. In the case of Alosa immaculata, a key migratory species of the lower Danube River, these adaptations can be assessed through hematological and biochemical indicators.

Chronic Granulomatous Disease: Clinical and Molecular Characterization of Brazilian Patients
The Journal of Gene Medicine, Volume 28, Issue 2, February 2026.Chronic granulomatous disease is a rare inborn error of immunity characterized by the deficient production of reactive oxygen species in phagocytes, which are used in pathogen elimination. Affected individuals become susceptible to severe infections.

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 2, Page 257-267, February 2026.Our results suggested that the difference in pregnancy outcomes between fresh and frozen embryo transfer is related to the peak estradiol level and embryo transfer stage. The cutoff values for peak estradiol level for performing freeze‐all strategy to improve pregnancy outcomes were different for cleavage‐stage and blastocyst‐stage embryo transfer ...
