iso-Migrastatin and related glutarimide-containing polyketides are potent inhibitors of tumor cell migration and their implied potential as antimetastatic agents for human cancers has garnered significant attention. Genome scanning of Streptomyces platensis NRRL 18993 unveiled two candidate gene clusters (088D and mgs); each encodes acyltransferase-less type I polyketide synthases commensurate ...

This second part of the revision of the Argentine species of Ora Clark, 1865 provides detailed redescriptions, habitus photos, illustrations of male and female genitalia for eight species, an identification key and updated distributions for all the species. A lectotype is hereby designated for Ora bruchi Pic, 1928. Scirtes brevenotatus v. mediolineatus Pic, 1928 and S. brevenotatus wagneri Pic,...

Comparative study of the removal of the dye Reactive Red 120 (RR-120) from aqueous effluents from textile industry using microalgae Spirulina platensis (SP) and commercial active carbon (AC) were carried out. The batch adsorption systems were evaluated with respect to pH, agitation time, temperature and initial concentration of the dye. The maximum adsorption capacity for dye RR-120 were found ...

A study was conducted with an objective to compare the efficacy of bentonite (BT), Spirulina platensis (SP) and glucomannan mycotoxin binders (GMA) on aflatoxicosis in broiler breeders. Three levels of AF, three binders and combination of different levels of AF with binders were evaluated. The Aflatoxin B1 (AF) fed at the levels of 300, 400 and 500ppb for three periods, each with duration of th...

OBJECTIVES Previous study has demonstrated that oleanolic acid (OA) possessing the anti-inflammatory and antioxidant properties, blunted high glucose induced diabetic cardiomyopathy, and ameliorated experimental autoimmune myocarditis in mice. However, little is known about its effects on pressure overload induced cardiac remodeling. Herein, we investigated the effect of OA on cardiac remodelin...

This paper presents a method to estimate the biomass of Spirulina cultivated on solid medium with sugarcane bagasse as a support, in view of the difficulty in determining biomass concentrations in bioprocesses, particularly those conducted in semi-solid or solid media. The genus Spirulina of the family Oscillatoriaceae comprises the group of multicellular filamentous cyanobacteria (blue-green m...

Export of Pink Lady apples from Australia has been significantly affected by infestations of adult eucalyptus weevils (Gonipterus platensis Marelli). These weevils cling tenaciously to the pedicel of apple fruit when selecting overwintering sites. As a result, apples infested with live G. platensis adults lead to rejection for export. Since the Montreal Protocol restricted use of methyl bromide...

Algae can tolerate a broad range of growing conditions but extreme conditions may lead to the generation of highly dangerous reactive oxygen species (ROS), which may cause the deterioration of cell metabolism and damage cellular components. The antioxidants produced by algae alleviate the harmful effects of ROS. While the enhancement of antioxidant production in blue green algae under stress ha...
