Published: June 1990

The current study tested whether the spontaneously hypertensive rats (SHR) from Charles River Laboratories are resistant or not to NaCl-induced rises of blood pressure and stroke deaths. These rats are fairly NaCl-resistant on a 2.1% high K diet, whereas they are quite susceptible to NaCl-induced hypertension and stroke deaths on a 0.5% normal K diet. Thus, a high K diet strongly protects against an NaCl-induced rise of blood pressure as well as stroke deaths in these SHR rats. Hence the level of dietary K determines the degree of NaCl sensitivity in these SHR rats.

Background: The link between obesity and cardiometabolic risk has been well recognized. We investigated the association between body fat percentage (BF%), as an appropriate indicator of obesity, and prevalence of cardiometabolic diseases using baseline data of Fasa PERSIAN cohort study.

Methods: The cross-sectional study was performed on data obtained at the first phase of the Fasa cohort study in Iran (n = 4658: M/F: 2154/2504).

Background: Early and continuous exposure to painful stimuli in premature infants leads to short-and long-term complications. Listening to white noise is an accessible and inexpensive non-invasive method that can be used as a safe nursing intervention in hospitals. This study aimed to assess white noise's effect on premature Infants' physiological parameters during peripheral intravenous catheter insertion.

Background: The cardiovascular consequences of night work are increasingly well-known. Implementing effective preventive strategies, however, requires further investigation of the effects of exposure duration. This study sought to assess the cumulative dose-effect of night work exposure on the prevalence of cardiovascular risk factors among current and former night workers in France.

Background: Prone position has been diffusely applied in mechanically ventilated COVID-19 patients. Our aim is ascertaining the association between the physiologic response and the length of the first cycle of prone position and intensive care unit (ICU) mortality.

Methods: International registry including COVID-19 adult patients who underwent prone positioning.

Background: Obesity plays a crucial role in the development of metabolic disorders including diabetes, coronary and renal diseases. There are several factors involved in the pathology of obesity, including chronic inflammation and exposure to environmental contaminants. Recently, the cholinergic co-hydrolyzing enzyme BChE has been associated with clinical conditions such as diabetes and obesity.
