OBJECTIVE To determine the clinical and biochemical effects of fasting during Ramadan on patients with cardiac disease. METHODS Eighty-six outpatients with heart disease with intention to fast were studied in the month of Ramadan 1996 (1416 H) at the King Fahd Armed Forces Hospital, Jeddah, Kingdom of Saudi Arabia. Detailed clinical and biochemical assessments were performed within 3 days bef...

We formulate quenched chiral perturbation theory for heavy-light mesons coupled to pions, and calculate the one-loop chiral logarithmic corrections to fB, fBs , BB and BBs . We also calculate these corrections for “partially quenched” theories. In both theories, the chiral logarithms diverge in the chiral limit, indicating that (partially) quenched theories should not be used to study this limi...

introduction: during ramadan, adult muslims abstain from drinking and eating from sunrise to sunset. this religious practice influences individuals’ lifestyle factors such as eating behavior, meal schedule, and sleep pattern. these changes may affect endocrine and neuroendocrine circadian patterns, and consequently, cardiovascular indices. this study was performed to investigate the effects of ...

fasting has numerous biological, physical and mental health advantages or that as some physicians cure their patients by prescribing fasting to them. fasting protects people from many diseases such as cancer, cardiovascular diseases, and diabetes complications. the main health-promoting effects of fasting are increased production of neurotrophic factors, neuroendocrine activation, hormetic stre...

Introduction: Elevated serum ferritin levels are associated with insulin resistance, type 2 diabetes and metabolic syndrome (MetS) as well as systemic inflammation and cardiovascular disease. The associations between ferritin and hemoglobin levels with individual components of MetS are unclear. The aims of the study were 1) to compare the ferritin levels, and 2) to investigate the relationships...

Background:The aim of this study was to evaluate the effect of Ramadan fasting on SIRT1 mRNA expression in healthy men.Islamic Ramadan fasting is a holy religious ceremony that has many spiritual benefits. Additionally, it can be considered as the equivalent of calorie restriction that may affect physical health. The results of previous studies revealed that calorie restriction increases the li...

OBJECTIVE To study the relationship of gamma glutamyl transferase (GGT) with insulin resistance markers [fasting insulin and Homeostasis Model Assessment of-insulin resistance (HOMA-IR)] and to assess the role of GGT as a determinant of insulin resistance in healthy obese children. MATERIAL AND METHODS Fifty healthy obese children (boys and girls with mean age 9.2 +/- 0.73 and 8.8 +/- 0.74 ye...

Purpose: The aim of this study was to compare biochemical tests, body composition and anthropometric parameters in Nonalcoholic Fatty Liver Disease (NAFLD) patients before and after Ramadan fasting. Methods: fifty NAFLD patients including 33 males and 17 females aged 18-65 year, were recruited. Subjects attended after diagnosis based on  ultrasound imaging, with at least 10 hour fasting, before...

OBJECTIVE Biochemical markers of bone turnover exhibit circadian rhythms with the peak during the night/early morning and the nadir in the late afternoon. The nocturnal increase in bone resorption could theoretically be caused by the absence of food consumption which brings about a decrease in net calcium absorption and an increase in parathyroid hormone (PTH), followed by increased bone resorp...

abstract   background: irregular working hours, including night work and shift work, have been found to be associated with alteration in various levels of biochemical factors. and some studies have showed association between shift work and blood biochemical disturbances in blood. in this epidemiological study we investigated, whether regular schedule of working hours can minimize the associated...
