Heavy metal and metalloid concentrations in red deer (Cervus elaphus) and their human health implications from One Health perspective.

The red deer is an ungulate and large game species. The contamination of the ecosystems by metal(loid)s may lead to the exposure of animals (as well as humans) through water and food resources. The direct contact of hunters and wild animal meat consumers with deer carcasses may be a potential contaminant source.

As Ceaseless as the Sea: How Modern Construction Machines Disrupted Canadian Senses and Sensibilities, 1870s-1940s.

Since the late nineteenth century, Canada has required modern construction machines for industrial growth. Thanks to their novelty and visibility, these machines entered the Canadian psyche, symbolizing hopes and fears about the relentless transformations of modernity. Metaphors depicting these machines as zoomorphic and monstruous reflected the environmental-technological infrastructures they built, which redefined nature through technologies like trains, ships, and automobiles.

A New Model of Air-Oxygen Blender for Mechanical Ventilators Using Dynamic Pressure Sensors.

Respiratory diseases are among the leading causes of death globally, with the COVID-19 pandemic serving as a prominent example. Issues such as infections affect a large population and, depending on the mode of transmission, can rapidly spread worldwide, impacting thousands of individuals. These diseases manifest in mild and severe forms, with severely affected patients requiring ventilatory support.

[Gastric emptying of liquids in rats submitted to acute myocardial infarction].

Gastric Emptying (GE) is food transition from the stomach to the upper small intestine. Haemodynamics changes modify gastric emptying and the gastroduodenal motor activity. Myocardial Infarction is a pathological condition in which there are haemodynamics changes.

Impact of long-term administration of amiodarone on the thyroid function of patients with Chagas' disease.

The effect of long-term treatment with amiodarone on patients with Chagas' disease has seldom been reported. This nonrandomized observational study attempted to analyze the follow-up of patients with Chagas' disease regarding their clinical evolution, thyroid dysfunction, and goiter. We compared 72 patients with long-term use (11 +/- 5 years) of amiodarone, including 22 patients who developed goiter, to 33 patients who did not use amiodarone, followed-up for 2 to 20 years (7 +/- 11 years).

Hypothalamic response to experimental allergic encephalomyelitis: role of substance P.

Adjuvant-induced arthritis (AA) is thought to be a model for experimental chronic stress that has as main features decreased adrenocorticotropin hormone (ACTH) plasma levels and a rise in median eminence content of arginine vasopressin (AVP) due to the activity of substance P. In experimental allergic encephalomyelitis (EAE), another chronic stress model, the role of substance P action is not clear. In this paper we tried to clarify the role of substance P in Lewis rats, which are susceptible to this disease.
