An adult patient with lysosomal acid alpha-glucosidase deficiency was fully investigated, and then placed on various forms of therapy with favourable response to a high protein, low carbohydrate diet. The rationale for the employment of this therapy, the problem of acid maltase deficiency and the relationship to weakness and glycogenosome formation with accumulation or otherwise of glycogen wit...

The onset of the adult form of Pompe disease, also known as acid maltase deficiency or glycogen storage disease type II, is a slow progressive muscular disorder in which little correlation exists between respiratory function and locomotor function [1]. The greater degree of respiratory dysfunction, compared with mobility loss, is mainly ascribable to the predominant and progressive involvement ...

Partially purified hot-water extracts of the roots of plants of the Sophora family suppressed the increase in blood glucose concentration of rats in the oral sugar tolerance test. The extracts also inhibited rat intestinal sucrase and maltase. The most potent sample was about 15 times more active than catechin, a positive control, in these experiments.

Feeding conditions during the nestling period may significantly affect whole-life fitness in altricial birds but little is known about the physiological mechanisms responsible for these effects. Permanent changes (irreversible developmental plasticity) in digestive physiology caused by the neonatal diet may form such a mechanism. We previously showed that the lack of starch in the diet of house...

In ovo feeding, injecting nutrients into the amnion of the avian embryo, may enhance jejunal nutrient uptake, activity of the intestinal enzymes, and posthatch growth. This hypothesis was tested in the following in ovo feeding (IOF) experiments. In experiment 1, 400 eggs were evenly distributed among 4 nutritional treatments at 23 d of embryonic development (23E) and administered 1 of 4 treatme...

OHNEDA, A., YAMAGATA, S., TSUTSUMI, K. and FuJIWARA, H. Distribution of Maltose Intravenously Administered to Rabbits and Its Metabolism in the Kidney. Tohoku J. exp. Med., 1974, 112 (2), 141-154 When 14C-U-maltose was injected intravenously to normal rabbits, 14C-maltose rapidly disappeared from the blood stream and circulating 14C-glucose rose gradually. In urine, 24% of total radioactivity w...

BACKGROUND/AIMS The etiopathogenesis of inflammatory bowel disease (IBD) is multifactorial and not well explained. Environmental, genetic, and dietary factors play an important role. The aim of the study was the evaluation of lactase, saccharase, and maltase activity in patients with IBD. MATERIALS AND METHODS The study comprised 65 children, aged 3-18 years. During a routine endoscopy, we to...

The meningococcus cell contains a peptonase enzyme which hydrolyzes the peptides and similar constituents of commercial "peptone." The activity of this enzyme is independent of the presence of the formed bacterial cell. The peptonase enzyme is more resistant to heat and to oxidation than is the maltase enzyme of the same bacteria.

Based on the concept of nutritional programming in higher vertebrates, we tested whether an acute hyperglucidic stimulus during early life could induce a long-lasting effect on carbohydrate utilization in carnivorous rainbow trout. The trout were fed a hyperglucidic diet (60% dextrin) at two early stages of development: either at first feeding (3 days, stimulus 1) or after yolk absorption (5 da...

Saccharomyces cerevisiae maltases use maltose, maltulose, turanose and maltotriose as substrates, isomaltases use isomaltose, α-methylglucoside and palatinose and both use sucrose. These enzymes are hypothesized to have evolved from a promiscuous α-glucosidase ancMALS through duplication and mutation of the genes. We studied substrate specificity of the maltase protein MAL1 from an earlier dive...
