Green tea infusion improves cyclophosphamide-induced damage on male mice reproductive system

open access: yesToxicology Reports, 2015
Green tea presents catechins as its major components and it has a potential antioxidant activity. Cyclophosmamide (CP) is an antineoplastic and immunosuppressive agent, known to reduce fertility. In the present study, we evaluated the effect of green tea

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1286-1298, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

The Red Queen unveils the sexual and mating strategies of flowers

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

Molecular and Serological Detection of Coxiella burnetii in Small Ruminants in Northeastern Brazil

open access: yesVeterinary Medicine and Science, Volume 12, Issue 2, March 2026.
• Serology indicates that one‐third of the sheep and goats had previously been infected with Coxiella burnetii. • qPCR analysis revealed the ongoing presence of C. burnetii in all evaluated flocks, each with a previous history of reproductive disorders. • These results indicate the need for preventive measures and control of C.

Cytologic Grading of Canine Mammary Tumors by Robinson's System Adapted to Romanowsky‐Type Rapid Staining: Prognostic Implications

open access: yesVeterinary Clinical Pathology, Volume 55, Issue 1, Page 55-67, March 2026.
ABSTRACT Background Mammary neoplasms are a major concern in intact female dogs, and cytologic examination is routinely used for initial screening. Although the adaptation of Robinson's cytologic grading system to canine species has been scarcely explored, it shows prognostic potential, particularly when correlated with other clinical and pathologic ...
