Objective: Alpha-glucosidase, as a carbohydratase catalyses the liberation of alpha-glucose from the nonreducing end of some carbohydrates from foods in digestive tract.  Consequently, retard absorption of glucose by the inhibition of carbohydrate hydrolyzing enzymes is one of the therapeutic approaches to decrease the postprandial hyperglycemia. Recently, a great deal of attention has been pai...

Endophytic bacteria are nearly ubiquitously present in the internal tissues of plants, and some endophytes can promote plant growth. In this study, we sampled the roots of four ancestral species of sugarcane (two genotypes per species) and two sugarcane cultivars, and used 16S rRNA and nifH gene sequencing to characterize the root endophytic bacterial communities and diazotroph diversity. A tot...

Background:α-Glucosidase Inhibition can significantly prevent glucose uptake after meal, and helps in controlling of some adverse effects in diabetics. So determination of α-Glucosidase inhibitory effect and antioxidant activity of the Haplophyllum acutifolium and Ferula haussknechtii aerial organs was the aim of this study.Methods:Inhibitory effect of hexane extracts from dif...

The New World species of the subgenera Allotrichoma Becker and Neotrichoma (new subgenus) are revised, including a phylogenetic analysis of the species groups and subgenera within the genus Allotrichoma. For phylogenetic perspective and to document the monophyly of the genus Allotrichoma and its included subgenera and species groups, we also provide a cladistic analysis of genera within the tri...

The Brazilian Atlantic Forest presents high levels of richness and endemism of several taxonomic groups. Within this forest, the Orchidaceae may be highlighted as the richest family of Angiosperms found there, and is highly threatened due to collection and habitat destruction. The inselbergs of the Brazilian Atlantic Forest are mostly unknown regarding their floristic composition, but the avail...

Solanum section Lasiocarpa includes about a dozen species with a center of diversity in theNewWorld tropics. Solanum lasiocarpum and S. repandum (sometimes considered to be conspeciŽc as S. ferox) have an Old World distribution in Asia and the PaciŽc Islands. Several species in this section produce edible fruits, and two, the lulo or naranjilla (S. quitoense) and the cocona (S. sessiliorum) ar...

Ratification of appointment of repositories by the International Mycological Congress is reported. The following two family names are recommended for conservation: Chrysotrichaceae against Pulverariaceae; and the teleomorphtypified Erysiphaceae against the anamorph-typified Oidiaceae. The following family name is not recommended for conservation: Dothioraceae against Saccotheciaceae. The follow...
