Antiproliferative activity was confirmed in the various extracts of rhizomes of Hedychium flavescens (Zingiberaceae). The phytochemical investigation of the rhizomes of Hedychium flavescens led to the isolation of four ...

BACKGROUND AND PURPOSE Betulinic acid (BA) is a naturally occurring triterpenoid widely distributed throughout the plant kingdom. We previously reported that BA inhibits lipopolysaccharide (LPS)-induced interleukin-6 ...

A triethylene glycol modified quinoline ester (PQTEG) is synthesised, which acts as a colorimetric sensor for Al3+ ions with a detection limit of 8 × 10−7 M in acetonitrile/water (95:5, v/v) solvent system. A visible colour ...

Triterpenes. stigmasterol, thwaitesii xanthone. apetalic acid. two new chromanones, decipic acid and 12-acetyl apetalic acid are isolated for the first time from the ethyl acetate extract of the bark of Calophyllum decipiens, ...

An efficient, pyridine-free protocol has been developed for the protection of the 3°-allyl alcohol of oxindole using a mild base, such as potassium carbonate, under microwave irradiation conditions. The methodology has ...

A seemingly ipso-like nucleophilic substitution of the upper rim of p-tert-butylcalix[4]arene is accomplished by an indirect method involving calix[4]arene derived bis(spirodienone). This method not only provides both mono ...

Mixed stones form a significant number of all urinary stones. Accurate analysis of individual areas of stones is fraught with uncertainties. Scanning electron microscopy with elemental distribution analysis (SEM-EDAX) is ...

Various crystals are seen in human urine. Some of them, particularly calcium oxalate dihydrate, are seen normally. Pathological crystals indicate crystal formation initiating urinary stones. Unfortunately, many of the ...

A novel class of efficient visible light sensitized antenna complexes of Eu(3+) based on the use of a highly conjugated b-diketonate, namely, 1-(4-biphenoyl)-3-(2-fluoroyl)propanedione (HBFPD) and 1,10-phenanthroline as ...

Foregut duplication cysts are developmental anomalies of the bronchopulmonary foregut and are common cystic lesions of the mediastinum. We describe a case of mediastinal foregut duplication cyst with in vivo H-1 MR ...
