Pradimicin S was isolated from the culture filtrate of Actinomadura spinosa AA0851. NMR and MS analyses proved that pradimicin S is the 3'-O-(3''-O-sulfo-beta-D-glucopyranosyl) analog of pradimicin A, a new member of the pradimicin family of antibiotics. Stereochemical assignment was made by correlating pradimicin S with pradimicin L.

We revise the genus Opisthoscelis Schrader, and erect the genus Tanyscelisgen. n. with Opisthoscelis pisiformis Froggatt as its type species. Species of both genera induce sexually dimorphic galls on Eucalyptus (Myrtaceae) in Australia, with Opisthoscelis subrotunda Schrader also in Papua New Guinea. We synonymise the following taxa (junior synonym with senior synonym): Opisthoscelis fibularis ...

BACKGROUND Strychnos spinosa Lam. is a deciduous tree used in traditional medicine to treat infectious diseases. This study is designed to determine the antimicrobial, antioxidant and cytotoxic activities of extracts and fractions from leaves of S. spinosa. METHODS Extracts were obtained by maceration with acetone, methanol and dichloromethane/methanol (1/1) while fractions were prepared by l...

Creatine modification for commercialization has included many variations to increase its stability. The current report assesses the stability of a sodium bicarbonate buffered creatine sold under the brand name Kre-Alkalyn under various conditions. Kre-Alkalyn is shown to have a good 6 year stability and shelf life under accelerated testing. It maintains a high pH over time compared to normal cr...

Background Preceding studies reported that differences in pressure distribution according to shoe type [1] and there were many comparative analyses of motor mechanics between travel shoes and general running shoes [2], but they were confined to research on pressure distribution of foot and studies on muscle activity and gait cycle depending on shoes heel were rare. Therefore, the purpose of thi...

Capparis spinosa ethanolic extract: phenol, flavonoid, antioxidant potential and antibacterial activity on Enterobacter aerogenesis, Escherichia coli, Staphylococcus aureus Listeria monocytogenes

Three species of Parastenheliidae were found at a sampling site around low tide level on St Martin’s Flat in the Isles of Scilly. The most abundant species in the community was identified as Parastenhelia ornatissima but detailed study, particularly of the previously unknown male, indicates that this species has a sexually dimorphic antenna and belongs in the genus Karllangia as K. ornatissima ...
