The association between a low urine pH and the components of metabolic syndrome in the Korean population: Findings based on the 2010 Korea National health and nutrition examination survey.

Background: Low urine pH is related to obesity and insulin resistance, which are components of metabolic syndrome (MS). The aim of this study was to identify the relation between a low urine pH and MS after controlled for other covariates including demographic and lifestyle factors in adult Korean population.

Materials And Methods: We analyzed data from the 2010 Korea National Health and Nutrition Examination Survey, a cross-sectional and nationally representative survey and 1960 men and 2702 women were included in this study.

Interactive effects of an isocaloric high-protein diet and resistance exercise on body composition, ghrelin, and metabolic and hormonal parameters in untrained young men: A randomized clinical trial.

Aims/introduction: The interactive effects of resistance training and dietary protein on hormonal responses in adults are not clear and remain controversial. We tested the effect of an isocaloric high-protein diet on body composition, ghrelin, and metabolic and hormonal parameters during a 12-week resistance training program in untrained healthy young men.

Material And Methods: We randomized 18 healthy young men to a standard diet (ST group) or an isocaloric high protein diet (HP group).

Adjustment of gut hormones release pattern following a fixed mealtime change in human.

Background: Gut hormones secretion is related to habitual mealtimes. However, how fast gut hormones adjust to that change when people change their fixed mealtime remains unknown.

Methods: Seven healthy male volunteers were asked to eat a test breakfast at 0700 am for 2 weeks before the start of the study.

The impact of bladder distension on blood pressure in middle aged women.

Background: The purpose of the present study was to investigate the relation between the extent of bladder distention and the rise of blood pressure in middle aged women.

Methods: In a cross-sectional, descriptive observational study, we obtained data from 172 middle aged women at a health promotion center of Pusan National University Hospital. We measured duration of urine-holding as the degree of the extension of bladder distention.

Analysis of questioning technique during classes in medical education.

Background: Questioning is one of the essential techniques used by lecturers to make lectures more interactive and effective. This study surveyed the perception of questioning techniques by medical school faculty members and analyzed how the questioning technique is used in actual classes.

Methods: Data on the perceptions of the questioning skills used during lectures was collected using a self-questionnaire for faculty members (N = 33) during the second semester of 2008.

Differential expression of ghrelin mRNA according to anatomical portions of human stomach.

Background/aims: The detailed ghrelin distribution on mRNA level in different anatomical portions of adult stomach and its association with plasma ghrelin levels are not yet well established. We investigated the ghrelin mRNA and peptide expression in different anatomical portions of stomach in human adults.

Methodology: Stomach tissue samples were obtained from 16 patients with gastric cancer who underwent total gastrectomy.
