The emergence and spread of microbial drug resistance and lack of developing new antibacterial bacteria are a growing problem in multi-drug - resistant bacteria, Phytochemical compounds and silver Nanoparticles (NPs) synthesis has been of great interest because of their potential biomedical applications. Hence this study was designed to evaluate the effect of Conocarpus lancifolius extracts s to control multidrug-resistant bacteria. Chemical detection of aqueous extracts of Conocarpus lancifolius leaves revealed the presence of tannin, Saponins, Comarins, phenols, alkaloids, flavonoids, glycoside and terpenes compounds. Results showed yield of phenols extracts of C. lancifolius were 46.1% while yield of extracts 22.2% alkaloids. AgNPs was proved by Atomic Force Microscopy. The average diameter of 75.50 nm. HPLC analysis indicated the presence of four phenolic compounds were Rutin, Epigenen and Kamferol and Catechine while contains two alkaloids Scopolamine and Hyoscine. Results showed that Conocarpus lancifolius extracts and AgNPs, possess higher antibacterial activity against both gram-positive and gram-negative pathogenic bacteria
The article presents materials on the species diversity of essential oil species of Turkestan semi-deserts flora. The ecological and coenotic patterns of their distribution are analyzed, the resources of promising essential oil plants are identified. Reserves of 10 essential oil-bearing species of Turkestan semi-deserts flora of the Republic of Kazakhstan are determined.
The purpose of the article is to analyze the dynamics of the life quality of patients with denture defect, with concomitant diseases of periodontitis on the basis of a comprehensive analysis and determine the use of a more appropriate treatment method of this pathology. In the analysis process, a survey was conducted among patients of the clinic. Based on the analysis results, conclusions were drawn that the life quality of patients after implantation made it possible to bring patients closer to practically healthy. It can be noted that the implantation method is more promising both for the life quality and for general well-being.
The article studies the capacity of two types of mustard to accumulate Pb from contaminated sierozem soils. The dependence between the degree of lead contamination of soil (from 150 to 550 mg/kg) and the intensity of its entry in the vegetative and generative organs of brown (Brassica Juncea L.) and white mustard (Sinapis Alba L.) have been thoroughly examined. It has been established that with an increase of Pb content in soil, there is increased content of this metal in organs of the above plants. The effect of vermicompost, sulfur- and perlite-containing waste and their mixtures, the lead behavior in the system of sierozem soil and mustard plants were studied. In conducted experiments, the following soil mass ratios were used: sulfur- and perlite-containing waste:vermicompost = 3:1:0.5. The introduction of vermicompost or its mixture with the sulfur- and perlite-containing waste into the contaminated soil helps to reduce the concentration of Pb, which passes into various plant organs. At the same time, the lead content in mustard organs decreases in the following order: the roots > leaves > stalks > grains. It was revealed that, despite the increased lead content in the soil (from 150 to 550 mg/kg of soil), its translocation amount in the grain portion of mustard does not exceed the standard maximum permissible concentration value for food products (MPC = 0.5 mg / kg).
In recent years, the chemical biology have attended significant progress in cyclo addition and cyclization reaction for synthesis many heterocyclic compounds, and here we reported one of the most utilized cofactor in cyclization reaction and discuss its function in most known synthesis reactions.
