Pollination of Peltogyne chrysopis: an endemic tree of the Atlantic Forest

open access: yesActa Botânica Brasílica
Peltogyne chrysopis is an arboreal legume endemic to the Atlantic Forest and known only from the state of Bahia, Brazil. Focal observations were made of anthesis, pollen availability, stigma receptivity, nectar production, and the presence of osmophores ...

Selenomethionine Regulates the Arachidonic Acid Metabolism‐Ferroptosis‐Inflammation Axis to Ameliorate Colitis

open access: yesAnimal Research and One Health, EarlyView.
Selenomethionine can ameliorate arachidonic acid‐induced colonic injury through synergistic mechanisms, including alleviating inflammatory responses, improving barrier integrity, enhancing antioxidant capacity by upregulating selenoprotein expression, selectively regulating AA metabolism to reduce pro‐inflammatory oxylipins and promote the production ...

Floral nectar: Fifty years of new ecological perspectives beyond pollinator reward

open access: yesPerspectives in Plant Ecology, Evolution and Systematics
Floral nectar is central to ecology, since it mediates interactions with pollinators, flower-visiting antagonists and microbes through its chemical composition. Here we review how historical assumptions about its ecological meaning were first challenged, then modified and expanded since the discovery of secondary metabolites in nectar.

Body donor programs in Australia and New Zealand: Current status and future opportunities

open access: yesAnatomical Sciences Education, Volume 18, Issue 3, Page 301-328, March 2025.
Abstract Body donation is critical to anatomy study in Australia and New Zealand. Annually, more than 10,000 students, anatomists, researchers, and clinicians access tissue donated by local consented donors through university‐based body donation programs. However, little research has been published about their operations.

The impact of family interview on the relationship between medical students and their silent mentor

open access: yesAnatomical Sciences Education, EarlyView.
Abstract The gross anatomy laboratory course often triggers significant negative emotions in medical students during dissection. While various pedagogical interventions aim to alleviate psychological burden, the fundamental question of how students' perceptions of donors evolve throughout the course remains underexplored.

Eudragit®‐engineered pH‐responsive probiotic microspheres with enhanced gastrointestinal resistance and prolonged storage stability for inflammatory bowel disease therapy

open access: yesBMEMat, EarlyView.
This study reports the development of AMS@Eud core‐shell microspheres, combining calcium alginate and pH‐responsive Eudragit® L100, which exhibit exceptional gastrointestinal resistance and long‐term storage stability (only 5.28%–9.09% viability loss over 35 days at 4–25°C), and effectively alleviate inflammatory bowel disease via gut microbiota ...

Controllable engineered probiotic microspheres for treating ulcerative colitis: A cascade enzyme‐catalyzed strategy to restore intestinal redox homeostasis

open access: yesBMEMat, EarlyView.
A dual strategy integrating genetic engineering and physical encapsulation was proposed to enhance the cell viability and antioxidant properties of probiotics. The cascade antioxidant enzymes released from probiotic microspheres restore intestinal redox homeostasis by eliminating intestinal reactive oxygen species for ulcerative colitis treatment ...

Kin discrimination in plants: overview and implications for population and community ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...
