Conditions for efficient transformation of Amycolatopsis orientalis (Nocardia orientalis) protoplasts by Streptomyces plasmid cloning vectors were identified. Three streptomycete plasmid origins of replication function in A. orientalis, as do the apramycin resistance gene from Escherichia coli, the thiostrepton resistance gene from Streptomyces azureus, and the tyrosinase gene from Streptomyces...

Launaea is a polymorphic genus with inter- and intraspecific inconsistencies. The study aimed to revise the classification identification of species in Egypt. also assess variation among taxa using macro- micromorphological characters. Numerical analysis was carried out on 156 specimens, which were collected from 63 sites results revealed that L. arabica, capitata, intybacea spinosa significant...

Amblyseius orientalis (Ehara) (Acari: Phytoseiidae) is a native predatory mite species in China. It used to be considered as a specialist predator of spider mites. However, recent studies show it also preys on other small arthropod pests, such as Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). Experiments were conducted to investigate (1) prey preference of A. orientalis between Tetranychu...

BACKGROUND Thuja orientalis has been traditionally used to treat patients who suffer from baldness and hair loss in East Asia. The present study sought to investigate the hair growth-promoting activity of T. orientalis hot water extract and the underlying mechanism of action. METHODS After T. orientalis extract was topically applied to the shaved dorsal skin of telogenic C57BL/6 N mice, the h...

Aphoristia (= Symphurus) orientalis Bleeker 1879, collected from an unspecified depth and location in Japanese waters, is the first described species of symphurine tonguefish from Indo-Pacific waters. The original description with accompanying illustration is based on the unique holotype specimen and provides limited diagnostic characters for this taxon. Subsequent to its description, the holot...

BACKGROUND Phlebotomus orientalis Parrot (Diptera: Psychodidae) is the main vector of visceral leishmaniasis (VL) caused by Leishmania donovani in East Africa. Here we report on life cycle parameters and susceptibility to L. donovani of two P. orientalis colonies originating from different sites in Ethiopia: a non-endemic site in the lowlands - Melka Werer (MW), and an endemic focus of human VL...

BACKGROUND Allergy is a clinical disorder affecting the human population with wide geographical distribution. Platanus orientalis (P. orientalis) trees are planted in many countries and their pollen causes allergic reactions. Cyclophilin has recently been identified as one of the most important allergens of P. orientalis pollen. We aimed to clone and purify this allergen in Escherichia coli for...

As per traditional knowledge, it is used in the treatment of insomnia, anxiety, neurosis, dry coughs, rheumatic pain, etc. [1]. The whole plant has also been used for the treatment of stomach problems, to stimulate digestion and to enhance appetite and relieve inflammation [2].The l...

Anti-inflammatory drugs presently available for the treatment of various inflammatory disorders have diverse and undesirable side effects. In recent years; active principles of varied chemical structures have been isolated from plants possessing anti-inflammatory activity. Sulfated polysaccharides present in algae were shown to posses anti-inflammatory properties. Ulva lactuca the green alga av...
