Pseudomonas aeruginosa is an important opportunistic pathogen causing widespread infections by numerous virulence factors. Increasing resistance to antibiotics makes the Pseudomonas infections treatment further difficult. The purpose of this study was to evaluate antimicrobial characteristics of essential oils from Matricaria chamomilla, Artemisia persica, Zataria multiflora, Myrtus communis, R...

Scrutinizing of different aspects in vegetative propagation of Iranian J. communis L. is of prime importance in order to prevent extinction of such valuable conifer. In this research, the effects of different seasons, gender, different chemical compounds (IBA, PBZ, putrescine and sodium nitroprusside) and three strains of Agrobacterium rhizogenes on ex-vitro rooting c...

The binding of iodinated wheat germ agglutinin, Ricinus communis agglutinin, and concanavalin A to mycoplasma cells and membranes was examined. All mycoplasmas studied specifically bound concanavalin A or R. communis agglutinin and, to a lesser degree, wheat germ agglutinin. The binding of lectins to whole cells was similar to that recorded for membranes, suggesting that significant binding on...

Epilachna vigintioctopunctata is an important pest that causes considerable economic losses to many crops including egg-plants. The crude aqueous extracts of leaves from three indigenous plants namely Ricinus communis, Calotropis procera and Datura metel were used against this beetle aiming at its control under laboratory conditions. Larvicidal bioassays of the extracts showed the following ord...

Objective: To assess neuromuscular transmission (NMT) in patients with Meniere's disease (MD), in which the precise etiology is unknown and a channelopathy hypothesis has been proposed Methods: Single fiber electromyography (SFEMG) during voluntary contraction of the extansor digitorum communis muscle, nerve conduction studies of upper and lower extremities and concentric needle electromyograph...

A thermotolerant ammonia-oxidizing bacterium strain JPCCT2 was isolated from activated sludge in a thermal power station. Cells of JPCCT2 are short non-motile rods or ellipsoidal. Molecular phylogenetic analysis of 16S rRNA gene sequences demonstrated that JPCCT2 belongs to the genus Nitrosomonas with the highest similarity to Nitrosomonas nitrosa Nm90 (100%), Nitrosomonas sp. Nm148 (99.7%), an...

Marino, P., Schicchi, R., Barone, E., Raimondo F. M. & Domina G.: First results on the phenotypic analysis of wild and cultivated species of Pyrus in Sicily. — Fl. Medit. 23: 237-243. 2013. — ISSN: 1120-4052 printed, 2240-4538 online. Phenotypic analysis of Pyrus in Sicily using a set of 19 characters on 71 accessions belonging to 7 species is here reported. Results show a high level of morphol...

This study was conducted to search for xanthine oxidase (XO) inhibitors from the root extracts of Tamus communis L. traditionally used in folk medicine in Algeria. Root extracts with different solvents were screened for purified milk xanthine oxidase inhibition. The root extracts (methanol, chloroform and ethyl acetate) and proteins, obtained in distilled water, inhibited bovine, sheep and huma...

The degradation and fermentation of cellulose filter paper were studied in axenic cultures of 3 species of rumen anaerobic fungi, Neocallimastix frontalis, Piromyces communis and Caecomyces communis, and in cocultures containing 1 of these fungal strains and Eubacterium limosum, a hydrogenotrophic rumen bacterial species. When E limosum was introduced into fungal cultures a slight decrease in f...
