Nano-chitosan as a bio-enhancer for improving insecticide formulations: A study on indoxacarb and methomyl against cotton leafworm.

This study was designed to improve the effectiveness and safety of two commercial insecticides, Camvaal EC 15 % (indoxacarb) and Nudrin SP 90 % (methomyl), against Spodoptera littoralis (Boisd.) through nanotechnology. Insecticide nanoemulsions were enhanced using nano-chitosan as a natural biopolymer.

NMR-based metabolomic analysis of wild, greenhouse, and in vitro regenerated shoots of subsp. with GC-MS assessment of proximadiol.

subsp is a wild plant distributed in subtropical and east Africa extending from the north to the southern parts of Egypt. Widely used in folk medicine, it is the source of the diuretic sesquiterpene proximadiol. Nuclear magnetic resonance metabolomic analysis of polar extracts of shoots from wild, greenhouse, somatic embryos, and direct and indirect organogenic in vitro cultures was carried out.

Multi-method assessment of patients with febrile illness reveals over-diagnosis of malaria in rural Uganda.

Background: Health clinics in rural Africa are typically resource-limited. As a result, many patients presenting with fever are treated with anti-malarial drugs based only on clinical presentation. This is a considerable issue in Uganda, where malaria is routinely over-diagnosed and over-treated, constituting a wastage of resources and an elevated risk of mortality in wrongly diagnosed patients.

Novel gold nanoparticles coated with somatostatin as a potential delivery system for targeting somatostatin receptors.

Targeting of G-protein coupled receptors (GPCRs) like somatostatin-14 (SST-14) could have a potential interest in delivery of anti-cancer agents to tumor cells. Attachment of SST to different nano-carriers e.g.

Fine structure of the dorsal lingual epithelium in Tarentola annularis and Crocodylus niloticus.

The present study examined the morphological features, histological and histochemical aspect of the tongue of two reptilian species, Tarentola annularis (family: Gekkonidae) and Crocodylus niloticus (family: Crocodylidea), with different habitats, feeding patterns and behaviours, by light and scanning electron microscope. It was observed, that the bifurcation of the tongue was more visible in Tarentola annularis. Conical and filamentous papillae were observed on the lingual body of Tarentola annularis, while in Crocodylus niloticus both mechanical filiform and gustatory papillae appeared.
