Mapping molluscan endocrinology: a systematic and critical appraisal

open access: yesBiological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Are Tetrapleura tetraptera Phytochemicals Druggable Against SARS‐CoV‐2 Papain‐Like Protein? A Computational Approach

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
SARS‐CoV2 Omicron and its substrains are still a critical global health issue and extremely contagious, even with widespread vaccination efforts. Hospitalizations and mortality rates linked to these variants are still prevalent. Current therapeutic options face challenges, including low effectiveness, suboptimal pharmacokinetics, and drug resistance ...

A contribution to the pathobiology of Biomphalaria glabrata hemocytes [PDF]

open access: yesMemórias do Instituto Oswaldo Cruz, 2006
This study attempts to investigate the relationship between the hemocytes in the two compartments: circulating peripheral lymph and the connective tissues. The hemocytes are compared with the vertebrate macrophages and constitute the principal line of defense against external aggression.
