Formulation‐Dependent Cytotoxic Effects of Commercial and Analytical‐Grade Mancozeb in C6 Glial Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Mancozeb (MZ) is a widely used dithiocarbamate fungicide composed of manganese (Mn) and zinc (Zn) complexes. Increasing concern has been raised regarding its occupational and human health relevance, particularly due to its neurotoxic potential associated with Mn‐related cellular dysfunction.

Biological Effects of Selenium‐Containing Ionic Liquids: Cytotoxicity, Mercury Interaction, and Antiproliferative Activity in Glioblastoma Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Selenium (Se) is an essential micronutrient that participates in redox regulation and cellular homeostasis. Selenium‐containing ionic liquids (ILsSe) have emerged as hybrid compounds combining the properties of organoselenium molecules with the tunable features of ionic liquids.

Nucleoside triphosphate diphosphohydrolase1 (TcNTPDase-1) gene expression is increased due to heat shock and in infective forms of Trypanosoma cruzi

Parasites & Vectors, 2014
Background Ecto-Nucleoside Triphosphate Diphosphohydrolases (Ecto-NTPDases) are enzymes that hydrolyze tri- and/or di-phosphate nucleotides. Evidences point to their participation in Trypanosoma cruzi virulence and infectivity.

Exposure–Recovery Approach for Hepatic Toxicity Analysis of Pyrethroid Lambda‐Cyhalothrin: Histopathological, Histochemical, and Biochemical Responses in Oreochromis niloticus

Journal of Applied Toxicology, EarlyView.
ABSTRACT Lambda‐cyhalothrin is a synthetic pyrethroid insecticide widely used in agriculture, but its potential to contaminate aquatic ecosystems and exert high toxicity on fish at low concentrations raises ecotoxicological concerns. While standard histopathological and biochemical assessments are common, the novel integration of pigment‐based ...

Total Immunoglobulin G Variation Through the Phenological Cycle of Migrant and Resident Lesser Long‐Nosed Bats (Leptonycteris yerbabuenae) in the Drylands of Mexico and Its Relationship With Bacterial Killing‐Ability of Plasma

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Bats have unique immunological characteristics among vertebrates. Understanding how the immune system responds during the life cycle of bat populations is crucial for grasping how their defenses against infection vary during critical life events.

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Rethinking Plasticity in Sponges

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
This systematic review critiques the conceptual confusion caused by the indiscriminate use of “plasticity” in Porifera literature, revealing that researchers often overlook genetic variability and fail to distinguish between real‐time environmental responses and natural selection.

Biotechnological applications of D-xylose-fermenting autochthonous yeasts in lignocellulosic biorefineries

Biotechnology for Biofuels and Bioproducts
The efficient fermentation of D-xylose by yeasts remains a major bottleneck for the sustainable production of second-generation bioethanol, as this pentose represents a substantial fraction of hemicellulosic sugars in lignocellulosic biomass.
