BACKGROUND AND OBJECTIVES Tissue advanced glycation end products (AGE) accumulation is a measure of cumulative metabolic stress. Assessment of tissue AGE by skin autofluorescence (SAF) correlates well with cardiovascular (CV) outcomes in diabetic, transplant, and dialysis patients, and may be a useful marker of CV risk in earlier stages of chronic kidney disease (CKD). DESIGN, SETTING, PARTIC...

Previously, Rhodotorula glutinis was reported to produce a large amount of exocellular mannan, having a repeating unit of -->3)-D-Manp-(1-->4)-D-Manp-(1-->. Recently, we found that antigenic polysaccharides of Leptospira biflexa serovar patoc strain Patoc I have the same repeating unit and cross-react with antisera raised against extended strains of other leptospires (K. Matsuo, E. Isogai, and ...

Endophytes and plants can establish specific long-term symbiosis through the accumulation of secondary metabolites. Previous studies have shown that the endophytic fungus Gilmaniella sp. AL12 can stimulate Atractylodes lancea to produce volatile oils. The purpose of this report is to investigate key factors involved in the stimulation of A. lancea by AL12 and reveal the mechanism. We identified...

Background: The molecular interaction between ligands of commensal microbiota and host receptors, such as Toll-like receptors (TLRs), at the surface of the epithelial cells of the gastrointestinal (GI) tract plays a critical role in its homeostasis and protection. The aim of this work was to determine the usefulness of the oral administration of yeast cells or soluble yeast-derived ligands for ...

The mechanisms associated with the cellular internalization of nanomedicines must be carefully considered when designing drug- and vaccine-delivery systems. The cellular fate and effects of nanomedicines depend to a large extent on the cell uptake routes. A self-assembled mannan nanogel is developed as a vaccination platform for antigen and adjuvant delivery. The mannan nanogel uptake by murine...

OBJECTIVE Patients with peripheral artery disease are at risk for critical limb ischemia and amputation. Accumulation of advanced glycation end products is increased and predictive for coronary and cerebrovascular events in several high cardiovascular risk groups. We hypothesized that accumulation of tissue advanced glycation end products, measured by skin autofluorescence (SAF), predicts amput...

background: most preclinical studies are carried out on mice. for internal dose  assessment of a mouse, specific absorbed fraction (saf) values play an important role.  in most studies, saf values are estimated using older standard human organ compositions  and values for limited source target pairs. objective: saf values for monoenergetic photons of energies 15, 50, 100, 500,  1000 and 4000 ke...

objectives: the aim of the present study was to investigate immunotoxic effect of safranal (saf), a main component of crocus sativus essential oil, using balb/c mice. materials and methods: saf was administered intraperitoneally at doses of 0.1, 0.5 and 1 ml/kg for 3 weeks. hystopathological examination of spleen and bone marrow, cellularity of spleen, delayed type of hypersensitivity (dth) res...

Sera from normal adult humans may contain high levels of antibody reactive with Candida albicans mannan. This study examined selected biological activities of such antibodies, focusing on sera that were collected from 34 donors and analyzed individually. The results showed that antimannan titers were normally distributed. Reactivity as determined by enzyme-linked immunosorbent assay with seroty...

A previously undescribed bovine serum lectin (designated CL-43) was identified by its Ca(2+)-dependent binding to mannan and by its molecular mass of 43 kDa under reducing conditions on SDS-PAGE. The lectin was isolated by polyethylene glycol precipitation, affinity chromatography on mannan-Sepharose (followed by elution with EDTA), and absorption on Sepharose-4B-coupled rabbit anti-bovine Ig (...
