Anais da Academia Brasileira de Ciências, 2016 We analyzed the diet of 25 individuals of Pseudis minuta tadpoles which consisted in debris with more than 30%, follow by diatoms, euglenids, green algae, and desmids. With regard to the feeding strategy, P. minuta tadpoles are generalist consumer.

Animals, 2023 Disruptive selection arises when extreme phenotypes have a fitness advantage compared to more-intermediate phenotypes. Theory and evidence suggest that intraspecific resource competition is a key driver of disruptive selection. However, while competition

FEBS Open Bio, EarlyView.KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

The island rule in the Brazilian frog Phyllodytes luteolus (Anura: Hylidae): incipient gigantism?
Zoologia (Curitiba), 2015 The island rule suggests that, when mainland animals are isolated on islands, large animals tend to become smaller, while small animals tend to become larger.

Regeneration in Hypophysectomized Anuran Tadpoles.
Experimental Biology and Medicine, 1960 Summary1. A comparison was made between regenerating tail-tips in normal and hypophysectomized Rana pipiens tadpoles. 2. No significant differences were noted in amount of regeneration/unit time or in the histology of regenerates. 3. Age of the hypophysectomized animal had no discernible effect on tail-tip regeneration. 4.

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

Advanced Functional Materials, EarlyView.A multivalent antiviral platform based on honeycomb‐shaped DNA nanostructures (HC–Urumin) is developed to enhance the potency and breadth of the host defense peptide Urumin. Through spatially patterned trimeric presentation, HC–Urumin disrupts influenza A virus entry, improves cell viability, and reduces disease severity in vivo‐offering a modular and ...

Advanced Functional Materials, EarlyView.Dicarboxylate‐modified anionic hairy cellulose nanocrystals exhibit a high selectivity for dysprosium(III) over neodymium(III). This selectivity arises from disordered dicarboxylate cellulose “hairs” that enable cooperative ionic coordination, hydrogen bonding, and strain‐induced conformational shrinkage.
