Acute effects of Zamzam water on blood pressure and heart rate variability.

Objective: There is a lack of studies exploring the effects of Zamzam water on human physiology. The present study determined the effects of Zamzam water on blood pressure and heart rate variability (HRV).

Methods: This comparative interventional study was conducted at the Department of Physiology, of our university in March 2018.

Determining the effectiveness of a cell phone-based student response system.

Objectives: This study aimed to explore the responses and understanding of students and teachers about the cell phone-based Socrative® application. Additionally, we compared the academic performance of the groups using Socrative with the one group that did not make use of this application.

Methods: During the 50 min of each endocrine physiology lecture, traditional teaching took 40 min, whereas the last 10 min were reserved for Socrative.

Effects of Zamzam water on glycemic status, lipid profile, redox homeostasis, and body composition in rats.

Objectives: Previous studies have demonstrated that Zamzam water exerts beneficial effects on several ailments such as diabetes mellitus, nephrotoxicity, hepatotoxicity, and stress. The present study aimed to assess the effects of Zamzam water on glycemic status, lipid profile, redox homeostasis, and body composition in healthy rats.

Methods: Twenty-four rats were divided into two equal groups.

Comparing levels of psychological stress and its inducing factors among medical students.

Objective: This study aimed to determine and compare degrees of psychological stress and inducing factors thereof among first to fifth year medical students (MS).

Methods: This cross-sectional study was conducted on 468 female MS. We used the Kessler 10 Psychological Distress Inventory consisting of questions on a range of stress-inducing factors.

Effects of chocolate intake on Perceived Stress; a Controlled Clinical Study.

Background: Cocoa polyphenols have been shown to reduce stress in highly stressed, as well as normal healthy individuals, we wondered whether commercially available chocolate could reduce perceived stress in medical students or not, so we decided to conduct this study.

Methods: Sixty students were divided into 3 groups (10 males + 10 females/group): i) Dark chocolate (DC) ii) Milk chocolate (MC) iii) White chocolate (WC). Subjects answered a PSS-10 (Perceived Stress Scale) questionnaire at baseline and after consumption of chocolate (40 g/day) for 2 weeks.

Molecular and pathological studies in the posterior interosseous nerve of diabetic and non-diabetic patients with carpal tunnel syndrome.

Aims/hypothesis: We sought to establish the molecular and pathological changes predisposing diabetic and non-diabetic patients to the development of carpal tunnel syndrome (CTS).

Methods: The posterior interosseous nerve (PIN) was biopsied in 25 diabetic and 19 non-diabetic patients undergoing carpal tunnel decompression for CTS. Detailed morphometric and immunohistological analyses were performed in the nerve biopsy.

Diabetic cardiomyopathy.

Diabetic cardiomyopathy is a distinct primary disease process, independent of coronary artery disease, which leads to heart failure in diabetic patients. Epidemiological and clinical trial data have confirmed the greater incidence and prevalence of heart failure in diabetes. Novel echocardiographic and MR (magnetic resonance) techniques have enabled a more accurate means of phenotyping diabetic cardiomyopathy.
