Diaryl-furanones are specific analytical reagents for the biochemical detection of primary amines by fluorescence techniques. Well-known fluorescamine (Fluram) and 2-methoxy-2,4-diphenyl-3(2H)-furanone (MDPF), yielding fluorescent products with λem at 480–490 nm. Although reaction claim to be pyrrolinones, recent studies show that they really 3-oxopyrrole (pyrrolone) derivatives. Both have been...

Transient precursor states are often experimentally observed for molecules adsorbing on surfaces. However, such precursor states are typically rather short-lived, quickly yielding to more stable adsorption configurations. Here we employ first-principles calculations to systematically explore the interaction mechanism for benzene derivatives on metal surfaces, enabling us to selectively tune the...

Heparin is a complex glycosaminoglycan, derived mainly from pig mucosa, used therapeutically for its anticoagulant activity. Yet, owing largely to the chain complexity, progressive effects of environmental conditions on heparin structure have not been fully described. A systematic study influence acidic hydrolysis length and substitution has therefore conducted. Changes in sulfation pattern, mo...

OBJECTIVES There has been a dramatic increase in the use of complementary medicines over recent decades. Glucosamine is one of the most commonly used complementary medicines in Western societies. An understanding of glucosamine consumption is of significance for public health and future health promotion. This paper, drawing upon the largest dataset to date with regards to glucosamine use (n = 2...

An< accurate, stable and very fast corner finder (for feature based vision) has been developed', based on a novel definition of corners, using:no image derivatives. This note describes the algorithm and the results obtained from its use.

BACKGROUND Renal cell carcinoma (RCC) is one of the most common types of cancer in urological system worldwide. Recently, the anticancer role of Glucosamine has been studied in many types of cancer. The aim of this study was to investigate the effects of Glucosamine on RCC. METHODS The effects of Glucosamine on RCC cell proliferation and apoptosis were investigated by MTT assay and Annexin V-...

A novel method was developed for production, recovery, and purification of fungal glucosamine. Fungal glucosamine is a good candidate for replacement of glucosamine obtained from shellfish wastes. Mycelium of the Rhizopusoryzae was treated with hot sodium hydroxide solution to obtain the fungal cell wall skeleton. Phosphates were removed from the cell wall by cold dilute sulfuric acid treatment...

Glucosamine is one of the most popular dietary supplements sold in the United States. Most clinical trials have focused on its use in osteoarthritis of the knee. The reported adverse effects have been relatively well studied and are generally uncommon and minor. No significant supplement-drug interactions involving glucosamine have been reported. The National Institutes of Health-sponsored Gluc...
