Exploring heavy metal dynamics and risks from dust and soil in urban cities of Jharkhand, India.

Jharkhand is a minerally prosperous state with geogenic and industrial origins of metals. This study assesses the seasonal variation of pseudo-total metal contents (Cr, Ni, Pb, Zn, Mn, Cu, Fe, Mg, Al) and related contamination and risks in indoor dust, street dust, and soils of four major cities of Jharkhand. Across cities and seasons, Zn, Cu, and Pb were the most common pollutants.

Objectives The primary objective of this article is to paint an institutional portrait of the Saint-Jean-de-Dieu Asylum over the first hundred years of its existence, from 1873 to 1973. The secondary objectives are as follows: 1) explore how prevention policies at the end of the 19th century had the effect of increasing the asylum population rather than reducing it; 2) discuss mental health policies that sought to "treat the social" outside the walls of the asylum in an effort to decrease the population; and 3) address the arrival of psychopharmacology that opened the doors of the asylum and turned it into a modern psychiatric hospital, soon renamed Louis-Hippolyte-Lafontaine. Method Since the past exists in silence, and finding data that will enable us to reconstruct a history of Saint-Jean-de-Dieu is a challenge.

Article Synopsis
- Vigilance in animals is essential for survival, as it impacts their ability to detect predators, which affects activities like foraging and mating; this study focuses on the Painted Stork in India, observing their nesting behaviors.* -
- The research found that male Painted Storks are more vigilant than females due to their roles in protecting the nest and territoriality, and that parental vigilance increases as their young nestlings age.* -
- Using camera techniques, the study identified that factors such as the number of visitors and neighbors, as well as specific habitat variables, significantly influence the storks' vigilance behavior, with higher levels observed at the National Zoological Park compared to Keoladeo National Park.*
Cultured primary turtle hepatocytes: a cellular model for the study of temperature and anoxia.

Turtle hepatocytes are a nonexcitable model for metabolic depression during low-temperature and/or anoxic overwintering conditions. Cytoskeletal structure and mitochondrial distribution are continuously modified in cells, and we hypothesized that metabolic depression would inhibit such processes as cell attachment and spreading and promote withdrawal of cell protrusions and peripheral mitochondria. After developing a methodology for culturing painted turtle hepatocytes, two-dimensional (2-D) area and maintenance of cell attachment after a media change were used as indicators of structural rearrangement and spreading/volume.
