Importance of Spring Habitats for Amphibians: The Case of Estavelle Ecotones in the Classical Karst Region

Animals
Springs are ecotones between groundwater and surface water, important for a variety of both surficial and subterranean organisms. However, their use by amphibians has been poorly assessed.

Angiotensin-(1-7) increases osmotic water permeability in isolated toad skin [PDF]

, 2000
Angiotensin-(1-7) (Ang-(1-7)) increased osmotic water permeability in the isolated toad skin, a tissue with functional properties similar to those of the distal mammalian nephron. Concentrations of 0.1 to 10 μM were effective, with a peak at 20 min. This

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Modulation of Trace Metal Accumulation in the Liver and Intestine of Amphibian Host Sclerophrys regularis by the Enteric Parasite Cosmocerca spp. Sampled in Lagos Metropolis, Nigeria

Journal of Basic and Applied Zoology, 2022
Background Recent studies have shown parasites as accumulation indicators that give critical information about the bioavailability of pollutants. To further buttress parasites in the assessment of metal sink potentials, the parasite Cosmocerca sp.

Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

FEBS Open Bio, EarlyView.
Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

First record of predation on Rhinella diptycha (Anura, Bufonidae) by Caiman latirostris (Crocodylia, Alligatoridae)

Actualidades Biológicas, 2020
Caimans of the species Caiman latirostris, which are widely distributed in South America, are opportunistic predators. They show ontogenetic variation in diet, with young individuals initially feeding on invertebrates and then gradually adding ...

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.

Very high water permeability in vasopressin-induced endocytic vesicles from toad urinary bladder. [PDF]

, 1989
The regulation of transepithelial water permeability in toad urinary bladder is believed to involve a cycling of endocytic vesicles containing water transporters between an intracellular compartment and the cell luminal membrane.
