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 panel of fifteen biotinylated lectins was used to study the saccharides associated with the epithelial component of normal and leukoplakic mucosa and squamous cell carcinoma, from a variety of locations in the oral cavity. Lectin binding heterogeneity was found between various sites of normal
Lectins from the seeds of Jackfruit (Artocarpus integrifolia) and winged bean (Psophocarpus tetragonolobus) were isolated using an immobilized N-acetyl D-galactosamine column and conjugated to type VI horse radish peroxidase. The purified conjugate was used for the study of tissue specificities
Bacteria and endotoxins can pass through the gut barrier under certain conditions. This process of bacterial translocation (BT) may occur after thermal injury in animals and is thought to play a role in the pathogenesis of septic complications in severely burned patients. The current study was
β-cyclodextrin modified with an electron-rich aromatic triazole linker and targeting moiety (galactosamine) was synthesized and studied as a carrier for the anticancer drug, doxorubicin (DOX), with the aim of targeting the pathological cells, reducing the cardiotoxic side effects and increasing the
A newly defined family of fungal lectins displays no significant sequence similarity to any protein in the databases. These proteins, made of about 140 amino acid residues, have sequence identities ranging from 38% to 65% and share binding specificity to N-acetyl galactosamine. One member of this
A water-soluble polysaccharide-peptidoglycan complex (PSPG) was prepared from heat-killed Lactobacillus casei by digesting the bacteria with N-acetylmuramidase. The molecular weight of PSPG was over 30,000, and the polysaccharide portion of PSPG, its main component was composed of rhamnose, glucose,
We have examined the influence of liver disease on drug absorption from the liver surface membrane, regarded as the first barrier for drug targeting to the liver. The main purpose of this study is to examine the possibility of direct liver surface application as a drug targeting method. We employed
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
Branched-chain amino acid aminotransferase activities were measured in rats in which hepatic lesions were induced experimentally, that is, fatty liver produced by an orotic acid-containing diet and acute hepatic lesion induced by D-galactosamine injection into the abdominal cavity. The levels of the
Human submandibular/sublingual saliva contains a protein that promotes adhesion of Streptococcus mutans JBP serotype-c to spheroidal hydroxyapatite in vitro. A high molecular-weight (250,000-300,000 Da) adhesion-promoting protein (APP) was purified by Trisacryl 2000 M gel-filtration chromatography
A characterization of the Amphibian Bufo arenarum oocyte envelope is presented. It was made in different functional conditions of the oocyte: 1) when it has been released into the coelomic cavity during ovulation (surrounded by the coelomic envelope, (CE), 2) after it has passed through the oviduct
An animal model of hepatocytic necrosis was established with injection of D-galactosamine into peritoneal cavity. Examination at regular intervals after injection showed that the level of increased serum TB, ALT and GST and the degree of histological changes in the liver were less marked in
OBJECTIVE
The study aimed to confirm bacterial translocation (BT) in rats with acute liver failure (ALF), to explore the correlation between the concentration of lipopolysaccharides and Toll-like receptor 4 (TLR4) expression, and further, to evaluate the curative effects of lactulose and
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
