Journal of Pineal Research, Volume 78, Issue 2, March 2026.ABSTRACT Reaching term gestation requires a complex interplay between the uterus and hormonal signals regulating its contractile profile. Most pregnancy‐associated hormones vary in their overall level of release throughout pregnancy, but also have a circadian release pattern, including progesterone, oxytocin, and melatonin. It remains poorly understood

Fertility and Early Embryonic Development Toxicity of hzVSF‐v13 in Sprague–Dawley Rats
Journal of Applied Toxicology, Volume 46, Issue 2, Page 560-568, February 2026.ABSTRACT Humanized virus suppressing factor–variant 13 (hzVSF‐v13), a monoclonal IgG4 antibody, is a potential therapeutic candidate for COVID‐19. Although fertility and embryonic developmental toxicity studies are crucial for the safety evaluation of new drugs, the toxicological profile of hzVSF‐v13 remains unexplored.

Longan flower water extract promotes sleep in mice via the serotonin–melatonin axis
Journal of the Science of Food and Agriculture, Volume 106, Issue 3, Page 1852-1860, February 2026.Abstract BACKGROUND Longan (Dimocarpus longan) flower is an underutilized botanical byproduct rich in polyphenols with reported neuroprotective actions, yet its role in sleep regulation remains unclear. This study aimed to evaluate the sleep‐promoting effects of longan flower water extract (LFWE) and its underlying neurochemical mechanisms in vivo ...

Validation of grizzly bear hair hormone profiles as a tool to monitor population demographics
The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.We measured 16 steroid and thyroid hormone concentrations in grizzly bear hair to predict sex, age class, and reproductive status. Models were highly accurate when predicting sex and age class and showed promise for assessing reproductive status. Results illustrate the potential for hair hormone profiles as non‐invasive population monitoring tools ...

Andrology, Volume 14, Issue 2, Page 555-570, February 2026.Abstract Background Predicting male fertility in farm animals remains a challenge. Seminal plasma (SP) contains a high amount of heterogeneous seminal extracellular vesicles (sEVs), believed involved in reproductive processes and maybe key to understanding male fertility.
