Bird's eye view of natural products for the development of new anti‐HIV agents: Understanding from a therapeutic viewpoint

open access: yesAnimal Models and Experimental Medicine, Volume 8, Issue 3, Page 441-457, March 2025.
Development of pharmaceutical drugs to cure HIV is crucial due to the current widespread epidemic. Nucleosides are the most effective anti‐HIV drugs, but their high toxicity and drug resistance limit their use. This review focuses on potential natural medicinal products for treating and managing HIV and AIDS.

Identification of pollen types of beekeeping interest by non‐targeted mass spectrometry

open access: yesJSFA reports, Volume 5, Issue 2, Page 62-73, February 2025.
Abstract Background The identification of pollen is important in the field of beekeeping for the determination of the botanical origin of bee products and investigations of bee diet. Until now, it has been performed by melissopalynology, the microscopic examination of pollen grains. However, this technique has some limitations, such as the necessity of

Rapid detection of RNase‐based self‐incompatibility in Lysimachia monelli (Primulaceae)

open access: yesAmerican Journal of Botany, Volume 112, Issue 1, January 2025.
Abstract Premise Primroses famously employ a system that simultaneously expresses distyly and filters out self‐pollen. Other species in the Primulaceae family, including Lysimachia monelli (blue pimpernel), also express self‐incompatibility (SI), but involving a system with distinct features and an unknown molecular genetic basis.

Differential effects of pollen nutritional quality on male and female reproductive success within a diverse co‐flowering community

open access: yesFunctional Ecology, Volume 39, Issue 1, Page 226-237, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollen protein content has been demonstrated to be an essential nutritional component for bees and thus important in mediating plant–pollinator interactions. However, little is known on the drivers and consequences of among‐species variation in pollen protein content ...
