Toxins, 2020 Ontogenetic changes in venom composition have been described in Bothrops snakes, but only a few studies have attempted to identify the targeted paralogues or the molecular mechanisms involved in modifications of gene expression during ontogeny.

Angewandte Chemie International Edition, Accepted Article.The interaction between the microtubule associated protein Tau and the tyrosine kinase Fyn is believed to play a pivotal role in the early stage of Alzheimer’s disease (AD). Previous studies have identified the SRC Homology 3 (SH3) domain of Fyn as the binding receptor of several proline‐rich motifs in Tau.

A Piece of the Lepton Theory from a Probability [PDF]
arXiv, 2001 A masses of a leptons deduced from a representation of a probability density vector by a spinors. A massive W and Z bosons and a massless A boson are obtained from a transformations for which a density vector is invariant.

On a question of A. Balog [PDF]
arXiv, 2015 We give a partial answer to a conjecture of A. Balog, concerning the size of AA+A, where A is a finite subset of real numbers. Also, we prove several new results on the cardinality of A:A+A, AA+AA and A:A + A:A.

Mammalian Phospholipase A2: Phospholipase A2 Receptor
Biological and Pharmaceutical Bulletin, 2004 The phospholipase A2 receptor (PLA2R) is a type I transmembrane glycoprotein related to the C-type animal lectin family such as the mannose receptor. PLA2R regulates a variety of biological responses elicited by secretory phospholipase A2s (sPLA2s). Group IB sPLA2 acts as an endogenous ligand to induce cell proliferation and lipid mediator production ...

The emerging roles of PAF acetylhydrolase
Journal of Lipid Research, 2009 Platelet-activating factor (PAF), a phospholipid autacoid with potent effects throughout the innate immune system, is selectively degraded by two small families of PAF acetylhydrolases (PAF-AHs).

Animal Research and One Health, EarlyView.Mechanisms of light in regulating the chick pineal clock. Abstract The circadian clock significantly impacts animal health and productivity, with light playing a crucial role in regulating circadian rhythms. However, the mechanisms behind light‐induced circadian transmission remain unclear, particularly in light‐sensitive avian species.

The effects of endocrine‐disrupting chemicals on ovarian‐ and ovulation‐related fertility outcomes
Molecular Reproduction and Development, Volume 89, Issue 12, Page 608-631, December 2022., 2022 Abstract Exposure to endocrine‐disrupting chemicals (EDCs) is unavoidable, which represents a public health concern given the ability of EDCs to target the ovary. However, there is a large gap in the knowledge about the impact of EDCs on ovarian function, including the process of ovulation.

Enumeration of symmetric centered rhombus tilings of a hexagon [PDF]
arXiv, 2013 A rhombus tiling of a hexagon is said to be centered if it contains the central lozenge. We compute the number of vertically symmetric rhombus tilings of a hexagon with side lengths $a, b, a, a, b, a$ which are centered. When $a$ is odd and $b$ is even, this shows that the probability that a random vertically symmetric rhombus tiling of a $a, b, a, a ...
