The purpose of this study was to investigate the effects of caffeine consume on substrate metabolism and acute hormonal responses to a single bout of resistance exercise (RE). Ten resistance-trained men participated in this study. All subjects performed one repetition maximum (1RM) test and then performed two protocols: caffeine (CAF, 6 mg·kg(-1)) and control (CON) in counter balanced order. Su...

BACKGROUND Sarcopenia is a debilitating condition afflicting the elderly that may be facilitated by insufficient or ineffectual intake of dietary protein. We previously showed that free-form essential amino acids acutely stimulate muscle protein synthesis in both the young and the elderly. However, the ability of an actual protein-rich food to stimulate anabolism in the young and the elderly ha...

OBJECTIVE To present the first case of eosinophilic fasciitis associated with L-tryptophan ingestion. CLINICAL FEATURES A 23-year-old Australian man developed myalgia and weakness, and later the clinical features of eosinophilic fasciitis, while taking L-tryptophan. INTERVENTION AND OUTCOME The amino acid supplementation was discontinued and he was treated with prednisone (30 mg/day) for si...

A method is described for monitoring the ingestion of isoniazid based on detecting its metabolites, isonicotinic acid, and isonicotinylglycine in the urine. The sensitivity of the method is high so that reliably positive results were obtained up to about 24 hours after the ingestion of 100 mg isoniazid. The method should facilitate monitoring the taking of isoniazid by tuberculosis patients and...

Metabolism and effects on platelet function of 6 g/d for 6 d of either eicosapentaenoic acid (EPA, C20:5 omega-3) or docosahexaenoic acid (DCHA, C22:6 omega-3) in volunteers were compared in a randomized crossover study. Incorporation kinetics revealed that EPA appeared in plasma free fatty acids and plasma phospholipids after 4 h, but was not incorporated into platelet phosphatidylcholine and ...

Microplastics are widespread in the marine environment, whereby uptake of these tiny particles by organisms, can cause adverse biological responses. Plastic debris also act as a vector many contaminants, herein depending on type, size, shape and chemical properties, possibly intensifying their effects organisms. This study aimed to assess accumulation potential toxicity different sizes micropla...

A patient who died in asystole less than 18 h after ingestion of 'Clovercide Extra', a combination hormonal weedkiller containing ioxynil and 4-chloro-2-methyl phenoxypropionic acid, is described. Previous reports describe coma as an early event following ingestion of these herbicides. In contrast our patient, although showing other characteristic features, including metabolic acidosis, tachyca...

The effect of aspirin (acetylsalicylic acid) ingestion on occult gastrointestinal blood loss has been studied in patients with treated Addisonian pernicious anaemia and proved achlorhydria and in control patients able to secrete hydrochloric acid. A highly significant increase in gastrointestinal blood loss (1.9 ml./day of treatment) occurred with aspirin ingestion in the achlorhydric patients....
