Evaluation of plasma peptides extraction methods by high-resolution mass spectrometry.

Monitoring of peptides offers a promising approach for the discovery of novel biomarkers, which might be valuable for detection, treatment and prevention of large variety of diseases. Development of highly effective methods for plasma peptide extraction remains an important task. In the current study, we applied different types of plasma peptide extraction approaches to reveal efficient methods which would provide the highest peptide yield.

Bacteriotherapy with Lactobacillus reuteri in rotavirus gastroenteritis.

Background: Certain lactic acid bacteria may accelerate recovery from acute diarrhea. Lactobacillus reuteri is a commonly occurring Lactobacillus species with therapeutic potential in diarrhea.

Design: Prospective, randomized, placebo-controlled trial in two hospitals.

A trial in the Karelian Republic of oral rehydration and Lactobacillus GG for treatment of acute diarrhoea.

In a controlled trial in Petrozavodsk, Karelia, the effects of oral rehydration and Lactobacillus strain GG (LGG) on recovery from acute diarrhoea (27% rotavirus, 21% bacterial aetiology) were studied in 123 children aged between 1 and 36 months of age. On admission to hospital, the patients were first randomized to receive either isotonic oral rehydration solution (ORS) with osmolarity 311 mosmol/l and sodium 90 mmol/l (WHO-ORS), or a hypotonic ORS with osmolarity 224 mosmol/l and sodium 60 mmol/l (Light-ORS), and thereafter randomized to receive either 5 x 10(9) colony forming units of LGG or a matching placebo. The two ORS performed equally for acute rehydration, and oral rehydration with either ORS was associated with a shorter duration of diarrhoea than intravenous rehydration (p = 0.

Lactobacillus reuteri as a therapeutic agent in acute diarrhea in young children.

Background: Certain strains of lactobacilli may promote recovery from acute diarrhea. Lactobacillus reuteri is of human origin and is a natural colonizer of gastrointestinal tract. In this trial, exogenously administered L.
