The microneme protein SML-2 is a member of a small family of galactose-specific lectins that play a role during host-cell invasion by the apicomplexan parasite Sarcocystis muris. The structures of apo SML-2 and the 1-thio-β-D-galactose-SML-2 complex were determined at 1.95 and 2.1 Å resolution,

OBJECTIVE To study the effect of Wu-He Dipsacus asper (WHDA), Traditional Chinese Medicine, injection on mice-aging model induced by D-galactose. METHODS Forty-eight Kunming mice (24 male and 24 female) were randomly divided into control group, model group, positive control group, 7.2 g/kg WHDA

In the oral microbial community, commensals can compete with pathogens and reduce their colonization in the oral cavity. A substance that can inhibit harmful bacteria and enrich beneficial bacteria is required to maintain oral health. The purpose of this study was to examine the effect of

Four of six human monoclonal IgM proteins were found to react best with Klebsiella polysaccharides containing 3,4py beta DGal (pyruvic acetalated D-galactopyranose), one with Klebsiella polysaccharides with 4,6pyDGlc; the sixth is uncharacterized. The combining sites of two of these (IgMWEA and

The influence of different galactose concentrations on the cariogenic effect of Streptococcus mutans (strains: DSM 20381 and DSM 20523) in a sucrose diet (33%) was examined in an animal experiment. The treated Wistar rats were free of pathogenic germs at the beginning of the experiment. The

We report the development of a sensor for rapidly and simultaneously measuring multiple sugars in aqueous samples. In this strategy, enzyme-based assays are localized within an array of individually addressable sites on a micromachined silicon chip. Microspheres derivatized with

Alzheimer's disease (AD) is a neurodegenerative disease characterized progressive memory loss and cognitive impairment. In previous studies, the activities of extracts of Chinese medicinal herbs to treat brain function disorders caused by AD have already been reported. ZiShen prescription was a

OBJECTIVE Fluorophore activation after cellular internalization of a targeted fluorescently labeled conjugate is an effective molecular imaging strategy to increase target-to-background ratios. The D-galactose receptor on ovarian cancer cells has been used to target self-quenched avidin-rhodamineX

A novel lectin from Talisia esculenta seeds (TEL) has recently been purified and characterized. In this study we investigated the proinflammatory activity of TEL in mice using both the air-pouch and peritoneal cavity as well as paw oedema models. TEL (10-40 microg) induced significant neutrophil and

The carbohydrate moieties of microfilariae (Mf) and infective larvae (L3) have been investigated by lectin-binding technique. Mf derived from three sources, namely, uteri (in utero), released in vitro from adults and from blood of rodents infected with Litomosoides carinii were examined by using

The Escherichia coli D-galactose and D-glucose receptor, an aqueous periplasmic receptor that triggers sugar sensing and transport, possesses a single Ca2+ binding site similar in structure and specificity to the EF-hand class of sites found in eukaryotic Ca2+ signaling proteins including calmodulin

CvL, a lectin from the marine sponge Cliona varians agglutinated type A papainized erythrocytes and was strongly inhibited by d-galactose and sucrose. Models of leukocyte migration in vivo were used to study the inflammatory activity of CvL through of mouse paw oedema and peritonitis. Effect of CvL

Blood contamination, such as bloody ascites or hemorrhages during surgery, is a potential hazard for clinical application of fluorescence imaging. In order to overcome this problem, we investigate if fluorescence-lifetime imaging helps to overcome this problem. Samples were prepared at

In order to study the human intestinal transit of flavan-3-ol C-glycosides, several C-glycosyl derivatives were prepared by non-enzymatic reaction of (+)-catechin with α-D-glucose, α-D-galactose and α-D-rhamnose, respectively. In contrast to literature data, we propose that the reaction mechanism

A lectin histochemical study was performed to investigate the distribution and changes of the oligosaccharidic component of the glycoconjugates in the lung of chick embryos, of 1-day-old chick, and of the adult animal. For this purpose, a battery of seven horseradish peroxidase-conjugated lectins
