Variation in facial bone growth remodeling in prehistoric populations from southern South America
(Veterinary and Human Toxicology, 2019-07)
Objectives: To assess the intraspecific variation in bone remodeling patterns in modern humans, we studied two populations from southern South America that represent the extremes of morphological variation in this region. ...
Development of the visual system of anchovy larvae, Engraulis anchoita : A microanatomical description
(Veterinary and Human Toxicology, 2020-04)
During the early ontogeny of fish larvae, the accurate development of the visual system plays a key role, because it is involved in locating food, orientation, selection of favorable habitat, and evasion of predators. The ...
Effect of Combined Action of Extracellular ATP and Elevated Calcium on Osteogenic Differentiation of Primary Cultures from Rat Calvaria
(Veterinary and Human Toxicology, 2016-11)
The in vitro osteogenic differentiation has been intensively studied. However, it is not yet clear precisely how osteogenesis can be optimized.Changes in extracellular Ca2þ concentration ([Ca2þ]e), as well as modulation ...
Synaptic signals mediated by protons and acid sensing ion channels
(Veterinary and Human Toxicology, 2019-06)
Extracellular pH changes may constitute significant signals for neuronal communication. During synaptic transmission, changes in pH in the synaptic cleft take place. Its role in the regulation of presynaptic Ca2+ currents ...
Oligodendrocytes and myelination: The role of iron
(Veterinary and Human Toxicology, 2009-04)
Iron is an essential trophic factor that is required for oxygen consumption and ATP production. Thus it plays a key role in vital cell functions. Although the brain has a relatively high rate of oxygen consumption compared ...
Rapid recovery of the beetle richness-elevation relationship and its environmental correlates after a major volcanic event in northwestern Patagonia, Argentina
(Veterinary and Human Toxicology, 2020-07-25)
Volcanic eruptions often modify the structure and function of ecosystems at large geographical scales. However, the extent to which species diversity patterns respond to these major natural disturbances is still poorly ...
Visitors' perceptions of zoo-housed lesser anteater (Tamandua tetradactyla) welfare: Observation plays a larger role than a brief informative talk
(Veterinary and Human Toxicology, 2020-10-10)
There is a growing ethical concern in modern society about animals' quality of life. We hypothesize that zoo visitors' perception of zoo animal welfare, particularly in the case of lesser anteaters, changes positively after ...
Reference ranges for knee height in Argentine children and adolescents aged 2 to 18 years
(Veterinary and Human Toxicology, 2020-05-30)
Objectives: Measurement of height is essential in the anthropometric assessment of growth and nutritional status. In some conditions, height measurement may be difficult or impossible. Proxy measurement such as knee height ...
Copulatory mechanics in the wolf spider Agalenocosa pirity reveals a hidden diversity of locking systems in Lycosidae (Araneae)
(Veterinary and Human Toxicology, 2019-10)
Genital traits are among the fastest to evolve, and the processes that drive their evolution are intensively studied. Spiders are characterized by complex genitalia, but the functional role of the different structures ...
Enantiomeric separation of β-blockers and tryptophan using heparin as stationary and pseudostationary phases in capillary electrophoresis
(Veterinary and Human Toxicology, 2018-05)
The separation methods of the enantiomers of two β-blockers and tryptophan were studied using capillary electrochromatography with heparin covalently as well as non-covalently, bonded onto the capillary inner wall as ...
