Increased plasma branched-chain amino acid concentrations are associated with insulin resistance, and intravenous amino acid infusion blunts insulin-mediated glucose disposal. We tested the hypothesis that protein ingestion impairs insulin-mediated glucose disposal by leucine-mediated mTOR signaling, which can inhibit AKT. We measured glucose disposal and muscle p-mTOR(Ser2448), p-AKT(Ser473), ...

We measured glutamine kinetics using L-[5-15N]glutamine and L-[ring-2H5]phenylalanine infusions in healthy subjects in the postabsorptive state and during ingestion of an amino acid mixture that included glutamine, alone or with additional glucose. Ingestion of the amino acid mixture increased arterial glutamine concentrations by approximately 20% (not by 30%; P < 0.05), irrespective of the pre...

Accidental corrosive ingestion is not a rare occurrence in children because of easy access to strong household cleansers. Gastric injury as a predominant finding following acid ingestion in pediatric age group is less widely known with a few cases being reported in Indian literature. We report two such cases of gastric outlet obstruction following accidental ingestion of dilute acid. Both child...

Acid ingestion in children is a common problem developing countries. Immediate complications of acid are oesophageal perforation, laryngeal trauma, bleeding and fistula formation but stricture delayed complication. Gastric outlet obstruction known complication acids surgery the mainstay treatment. Heineke-Mikulicz pyloroplasty was done five cases without outcomes were satisfactory.

Corrosive ingestion can cause serious damage to the upper gastrointestinal tract. The acute consequences could range from mild erythema to gangrene and perforation. Delayed consequences could be strictures of the oesophagus presenting as dysphagia or gastric, pyloric and antral stenosis presenting as gastric outlet obstruction. Gastro-colic fistula as a complication of acid ingestion is a rare ...

Increasing amino acid availability (via infusion or ingestion) at rest or postexercise enhances amino acid transport into human skeletal muscle. It is unknown whether alterations in amino acid availability, from ingesting different dietary proteins, can enhance amino acid transport rates and amino acid transporter (AAT) mRNA expression. We hypothesized that the prolonged hyperaminoacidemia from...

Timing of nutrient ingestion has been demonstrated to influence the anabolic response of muscle following exercise. Previously, we demonstrated that net amino acid uptake was greater when free essential amino acids plus carbohydrates were ingested before resistance exercise rather than following exercise. However, it is unclear if ingestion of whole proteins before exercise would stimulate a su...
