Many plants and plant parts have been used in traditional medicine for centuries, yet their possible toxic effects associated with their use have not been studied. In this study, we tested the in vitro antioxidant ability ...

Antimicrobial peptides (AMPs) represent alternative strategies to combat the global health problem of antibiotic resistance. However, naturally occurring AMPs are generally not sufficiently active for use as ...

A simple and fast procedure that allows the separation of small (1–3 kDa) peptides on glycine-SDS gels is described. Peptides were separated by glycine-SDS/PAGE as a result of in situ complexation of peptide/SDS during ...

A multifunctional reagent based on a coumarin scaffold was developed for derivatization of naive RNA. The alkylating agent N3BC [7-azido-4-(bromomethyl)coumarin], obtained by Pechmann condensation, is selective for uridine. ...

Phytoextraction has been introduced as a new technology to clean up soils contaminated with heavy metals as the use of conventional methods to clean up the soil is very expensive and destructive to the ecosystem. However, ...

Cotesia sesamiae (Cameron) is an indigenous larval endoparasitoid that attacks mid- to late-stage gramineous stem borer larvae in Africa. Two biotypes ofC.sesamiae have been reported with differential abilities to suppress ...

Hypolimnas misippus is a polymorphic and mimetic butterfly with a pantropicaP distribution. The polymorphism is autosomal and female-limited, the several female forms being generally regarded as Batesian mimics of the ...

Examination of 300 recovery records of Fulmars ringed in Britain allowed the distribution and movements of birds of known age to be described. Biases in the methods of recovery made estimation of mortality impossible. ...

The polymorphism of Danaus chrysippus is anomalous since it is a distasteful butterfly. In a field study of the B locus polymorphism in Ghana, significant changes in the morph frequencies were recorded over eighteen months ...
