The present study investigated potential sex-related differences in the metabolic response to carbohydrate (CHO) ingestion during exercise. Moderately endurance-trained men and women (n = 8 for each sex) performed 2 h of cycling at approximately 67% Vo(2 max) with water (WAT) or CHO ingestion (1.5 g of glucose/min). Substrate oxidation and kinetics were quantified during exercise using indirect...

Foreign body ingestion in children is common. Most items pass spontaneously, however rarer cases may result in obstruction and or perforation. Ingestion of multiple magnetic items can be more troublesome, as a consequence of the ability of the items to attract across different sections of bowel, or by coalescing to form a larger foreign body. Very few cases of foreign body ingestion have led to...

Nickel concentration in serum and whole blood as well as nickel excretion in urine was assayed at different time intervals before and after ingestion of nickel sulfate in eight healthy volunteers during a three days study. The peak level of nickel in blood was reached 2.5 hours after nickel ingestion and the maximal urinary excretion of nickel was during the first eight hours after ingestion. G...

Ingestion of acid-containing household products, either accidentally or as a suicide attempt, is a common form of intoxication. A clear and odorless liquid, hydrogen peroxide is an oxidizing agent found in most households and many industrial environments. Cardiovascular manifestations of hydrogen peroxide ingestion are extremely rare. Here we report a 60 year-old woman with acute inferolateral ...

To determine the effects of moderate ethanol consumption on the mechanical, biochemical, and structural characteristics of the heart, myocardial mechanical performance, contractile protein enzyme activity, and the number and size of myocytes were measured in male Fischer 344 rats after the ingestion of 30%o oral ethanol. Papillary muscles removed from the left ventricle were greater in length, ...

In this article we explore sources and magnitude of positive and negative error in soil ingestion estimates for children on a subject-week and trace element basis. Errors varied among trace elements. Yttrium and zirconium displayed predominantly negative error; titanium and vanadium usually displayed positive error. These factors lead to underestimation of soil ingestion estimates by yttrium an...

Whey protein ingestion has been shown to effectively stimulate postprandial muscle protein accretion in older adults. However, the impact of the amount of whey protein ingested on protein digestion and absorption kinetics, whole body protein balance, and postprandial muscle protein accretion remains to be established. We aimed to fill this gap by including 33 healthy, older men (73 ± 2 yr) who ...

The majority of foreign body ingestions occur in the pediatric population, with a peak incidence between the ages of 6 months and 6 years. Safety during dental treatment of children cannot be overemphasized. Uncooperative, mentally and physically handicapped children are more prone to ingestion or aspiration of dental instruments than other populations. In any event, it is recommended that dent...
