Northern elephant seals experience prolonged periods of absolute food and water deprivation (fasting) while breeding, molting or weaning. The postweaning fast in elephant seals is characterized by increases in the renin-angiotensin system, expression of the oxidant-producing protein Nox4, and NADPH oxidase activity; however, these increases are not correlated with increased oxidative damage or ...

the aim of this study was to assess public knowledge about the effects of ramadan fasting on various aspects of health and its association with fasting decision-making. this cross-sectional study was conducted on 600 subjects. the association between fasting and participants’ knowledge and attitudes toward ramadan fasting, anthropometric measurements, physical activity, depression, anxiety, str...

INTRODUCTION Muslims abstain from food and fluid between the hours of sunrise to sunset, and usually eat a large meal after sunset and a lighter meal before sunrise. The purpose of this study was to assess body composition, nutrient intake and physical activity patterns during Ramadan fasting. METHODS This study was carried out during Ramadan in October 2004. A total of 57 female subjects wer...

BACKGROUND: Fasting is an alternative method to induceanorexia. OBJECTIVES: The biochemical factors of liver andserum and clinical signs were measured and documented in fivenon-lactating, non-pregnant cows following eight days of fasting.METHODS:Five crossbred, non-lactating, and non-pregnantcattle were used in this study. They were fasted for 8 days_ totalfood deprivation; however, they had fr...

The magnitude of endogenous contamination of various perfusion techniques used to study water and electrolyte absorption in humans was examined indirectly by comparing rates of water and sodium absorption from saline and glucose-saline mixtures administered by both the double-lumen and triple-lumen techniques. Both perfusion systems are pictured, and their construction described. Double-lume ...

Although detailed scientific studies on starvation physiology have been conducted since the ninteenth century, there is little uniformity in the terminology used to describe it. The term ‘‘fast’’ usually applies at the end of the postprandial period (basal or postabsorptive state). In this state, however, the digestive tract may still possess nutrients that can still be absorbed. This review wi...

OBJECTIVE Fasting is not routinely recommended for renal function tests, despite the known effects of cooked meat on creatinine. We therefore studied variation in creatinine and estimated glomerular filtration rate (eGFR) after a standardized cooked meat meal in 80 subjects: healthy volunteers and diabetic patients with chronic kidney disease (CKD) stages 1 and 2, 3a, 3b, and 4 (n = 16/group). ...

The finding that tissue δ(15)N values increase with protein catabolism has led researchers to apply this value to gauge nutritive condition in vertebrates. However, its application to marine mammals has in most occasions failed. We investigated the relationship between δ(15)N values and the fattening/fasting cycle in a model species, the fin whale, a migratory capital breeder that experiences s...

Although thermal esophageal injuries caused by hot food or tea have been reported, thermal esophageal injury due to sodium picosulfate with magnesium citrate (PSMC) used for bowel preparation is rarely reported. We report the case of a 56-year-old man who presented with esophageal injury after ingestion of PSMC. Instead of dissolving the PSMC in water before ingestion, he drank water immediatel...

BACKGROUND Clitoria ternatea L., a natural food-colorant containing anthocyanin, demonstrated antioxidant and antihyperglycemic activity. The aim of this study was to determine the effects of Clitoria ternatea flower extract (CTE) on postprandial plasma glycemia response and antioxidant status in healthy men. METHODS In a randomized, crossover study, 15 healthy men (ages 22.53 ± 0.30 years; w...
