Design and Implementation of a Novel Double-Layered Wavy Mattress for the Prevention and Recovery of Pressure Ulcers: A Feasibility Study.

Pressure ulcers are a significant concern in patient care, particularly for those with limited mobility and extended hospital stays. Wavy mattresses are shown an effective tool for preventing or promoting the healing of these wounds by preventing pressure localization in different body regions. The current study aimed to present a novel double-layered wavy mattress design for the prevention and recovery of pressure ulcers, addressing some of the limitations of existing mattresses.

Effect of Rheum Ribes Hydro-Alcoholic Extract on Memory Impairments in Rat Model of Alzheimer's Disease.

Some animal models have been used to study Alzheimer's disease (AD). AD is an irreversible progressive neurodegenerative disease and the most common cause of dementia. Animal studies have shown that there is a relation between decrease in cholinergic functions in the nucleus basalis of Meynert (NBM) and loss of learning capability and memory.

Nandrolone Plus Moderate Exercise Increases the Susceptibility to Lethal Arrhythmias.

Background: Until now, no experimental study has directly assessed the arrhythmogenesis of chronic consumption of anabolic androgenic steroids along with moderate-intensity endurance exercise.

Objectives: We evaluated the influence of integration of anabolic androgenic steroids along with moderate-intensity endurance exercise on susceptibility to lethal ventricular arrhythmias in rat.

Materials And Methods: The animal groups were as follows: control group (CTL); exercise group (EX) which were under 6 weeks of treadmill exercise; nandrolone group (Nan) which received 5 mg/kg of nandrolone decanoate twice a week; vehicle group (Arach) which received Arachis oil (solvent of nandrolone); trained vehicle group (Arach + Ex); and trained nandrolone group (Nan + Ex).

Assessment of Safety and Therapeutic Efficacy of Rosa damascena L. and Quercus infectoria on Cardiovascular Performance of Normal and Hyperlipidemic Rabbits: Physiologically Based Approach.

According to the use of Quercus infectoria (QI) and Rosa damascena L. (RD) for therapeutic purposes and lack of adequate information about their cardiovascular effects, we investigated the cardiovascular indices of rabbits which chronically pretreated with these agents. Animal groups were control group (CTL), RD and QI groups with normal chow plus 1.
