Morphology of the digestive gland of the marine panpulmonate limpet Siphonaria lessonii: A cytological, histochemical, and ultrastructural description
(Veterinary and Human Toxicology, 2019-10)
The molluskan digestive gland has been widely studied and its structural and ultrastructural descriptions have allowed the understanding of its several functions. Despite siphonarids are broadly distributed around the ...
Aquaporin-2 and Na+/H+ exchanger isoform 1 modulate the efficiency of renal cell migration
(Veterinary and Human Toxicology, 2019-10)
Aquaporin-2 (AQP2) promotes renal cell migration by the modulation of integrin β1 trafficking and the turnover of focal adhesions. The aim of this study was to investigate whether AQP2 also works in cooperation with Na+/H+ ...
Phosphatidic acid and diacylglycerol generation is regulated by insulin in cerebral cortex synaptosomes from adult and aged rats
(Veterinary and Human Toxicology, 2005-07)
Insulin receptor associated with the cerebral cortex (CC) has been shown to be involved in brain cognitive functions. Furthermore, deterioration of insulin signaling has been associated with age-related brain degenera tion. ...
Five novel inactivating mutations in the thyroid peroxidase gene responsible for congenital goiter and iodide organification defect
(Veterinary and Human Toxicology, 2003-12)
Thyroid peroxidase (TPO) defects, typically transmitted as autosomal recessive traits, result in hypothyroid goiters with failure to convert iodide into organic iodine. We analyzed the TPO gene in 14 unrelated patients ...
Selective Cre-mediated gene deletion identifies connexin 43 as the main connexin channel supporting olfactory ensheathing cell networks
(Veterinary and Human Toxicology, 2019-05)
Many functions of glial cells depend on the formation of selective glial networks mediated by gap junctions formed by members of the connexin family. Olfactory ensheathing cells (OECs) are specialized glia associated with ...
Histomorphological changes in testes of broad-snouted caimans (Caiman latirostris) associated with in ovo exposure to endocrine-disrupting chemicals
(Veterinary and Human Toxicology, 2016-01)
Studies regarding the effects of endocrine-disrupting chemicals (EDCs) on the reproductivefunctions of wild animals have raised increasing concern. Thus, here we evaluated theconsequences of in ovo exposure to endosulfan ...
Phylogenetic analysis of SARS‐CoV‐2 in the first few months since its emergence
(Veterinary and Human Toxicology, 2020-09)
During the first months of SARS‐CoV‐2 evolution in a new host, contrasting hypotheses have been proposed about the way the virus has evolved and diversified worldwide. The aim of this study was to perform a comprehensive ...
Ghrelin and NUCB2/Nesfatin-1 Co-Localization With Digestive Enzymes in the Intestine of Pejerrey (Odontesthes bonariensis)
(Veterinary and Human Toxicology, 2019-06)
Ghrelin (orexigenic) and nesfatin-1 (anorexigenic) are two peptides with opposing actions on food intake regulation and are mainly expressed in the hypothalamus and gut of mammals and fish. Both are involved in the regulation ...
The species richness-elevation relationship: global patterns of variation in chironomid richness in mountain lakes
(Veterinary and Human Toxicology, 2019-01-28)
Abstract. 1. The species richness-elevation relationship (SRE) is predominantly hump-shaped along terrestrial gradients, but has been less explored in aquatic environments. Chironomids were used to evaluate the generality ...
Protein electrophoresis in Andean condors (Vultur gryphus): Reference values and differences between wild and rehabilitating individuals
(Veterinary and Human Toxicology, 2019-12)
The study of wildlife health greatly contributes to understanding population dynamics and detecting conservation threats. The determination of the different fractions of plasma proteins (proteinogram) is an important ...
