Reproduction and Development in Calcareous Sponges: A Panorama of the Last Two Centuries

open access: yesMolecular Reproduction and Development, Volume 93, Issue 7, July 2026.
ABSTRACT Nearly 200 years ago, scientists began examining reproductive cells in calcareous sponges (Calcarea, Porifera). Since then, 238 studies have been published, encompassing descriptions of gametes and embryos (including ultrastructural studies), life history, asexual reproduction, regeneration, and molecular aspects of development.

Avaliação do desenvolvimento larval de Anopheles darlingi criado em laboratório sob diferentes dietas Evaluation of the larval development of Anopheles darlingi (Diptera - Culicidae) raised in the laboratory on different diets

open access: yesRevista de Saúde Pública, 1990
São testadas três dietas para larvas de A. darlingi, buscando-se os seguintes parâmetros indicativos de desenvolvimento nesta fase: tempo de evolução total e de cada estádio, sobrevivência ao estádio, diária e total. A metodologia utilizada na determinação desses parâmetros constitui-se da combinação de dois métodos de análise da estatística vital ...

First Zoeal Stage of the Snapping Shrimp Alpheus Fabricius, 1798 (Caridea: Alpheidae): New Description of Alpheus bouvieri A. Milne‐Edwards, 1878 and Literature Review

open access: yesActa Zoologica, Volume 107, Issue 3, Page 361-376, July 2026.
ABSTRACT Based on adult morphological characters, the more than 300 species of Alpheus were divided into seven informal species groups, but some groups are not supported by molecular data. The aim here was to describe the zoea I of Alpheus bouvieri, and to do a review of the larval descriptions available in the literature, analysing whether the ...

Probing Cinnamamides and Benzamides as Anthelmintics: Discovery of Potent Drug‐Like Agents Against Angiostrongylus cantonensis

open access: yesChemical Biology &Drug Design, Volume 108, Issue 1, July 2026.
Cynnamoyl benzylpiperazine was identified as drug‐like derivative of cinnarizine with anthelmintic activity against A. cantonensis. In this work, 15 out of 31 derivatives showed improved anthelmintic activity with increased solubility. A SAR study was carried out to determine the molecular features involved in such effect.
