Neurology, 2013 Editors' Note: Dr. Egan inquires about the possibility of Tournay phenomenon in Kawasaki and Mayer's "Tadpole pupil." Dr. Charles, in reference to "Disease-modifying drugs for multiple sclerosis in pregnancy: A systematic review," suggests that it might be appropriate to continue glatiramer acetate in women trying to conceive given the lack of evidence

The Individual and Combined Effects of Warming and Atrazine on Lithobates pipiens Phenotypes: Implications for Frog Declines. [PDF]
J Exp Zool A Ecol Integr PhysiolABSTRACT Amphibians are the most threatened vertebrate class globally. Climate change, agrochemicals, and/or pathogens and parasites are implicated in contributing to amphibian declines, either singly or in combination. We investigated individual and combined effects of elevated temperatures and atrazine (2.0 μg/L) on Lithobates [formerly Rana] pipiens

Journal of High Energy Physics, 2021 Abstract We examine the mechanism of moduli stabilization by fluxes in the limit of a large number of moduli. We conjecture that one cannot stabilize all complex-structure moduli in F-theory at a generic point in moduli space (away from singularities) by fluxes that satisfy the bound imposed by the tadpole cancellation condition ...

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene-Edited Xenopus Tadpoles. [PDF]
J Pineal ResABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.

Class A Scavenger Receptors Are Used by Frog Virus 3 During Its Cellular Entry
Viruses, 2019 Frog virus 3 (FV3) is the type species of the genus Ranavirus (family Iridoviridae). FV3 and FV3-like viruses are globally distributed infectious agents with the capacity to replicate in three vertebrate classes (teleosts, amphibians, and reptiles).

Microhabitat features determine the tadpole diversity in mountainous streams
Ecological Indicators, 2021 The study on the mechanism driving the spatial patterns of biological diversity along elevational gradients is a main focus in ecology, biogeography, and conservation biology.

Antipredator pheromones in amphibians: a review
Veterinární Medicína, 2006 Specific chemosignals (pheromones) have an important role in the antipredator behaviour in amphibians and other vertebrates. However, relatively little is known about the occurrence of chemical alarm cues just in amphibians.

Journal of High Energy Physics, 2023 The tadpole conjecture proposes that complex structure moduli stabilisation by fluxes that have low tadpole charge can be realised only at special points in moduli space, leading generically to (large) gauge symmetries.

Analytic tadpole coefficients of one-loop integrals
Journal of High Energy Physics, 2021 One remaining problem of unitarity cut method for one-loop integral reduction is that tadpole coefficients can not be straightforward obtained through this way. In this paper, we reconsider the problem by applying differential operators over an auxiliary

Diversity, 2022 Reduced trophic resources can pose relevant constraints to the development of freshwater animals with complex life cycles. For amphibians, food deprived environments, such as high-altitude ponds and springs and groundwaters are frequently used for ...
