in this research, the inhibitory effects of silver nanoparticles and zinc oxide nanoparticles, in vitro, on disease stone fruits bacterial canker caused by pseudomonas syrigae pv. syringae and disease bacterial blight caused by xanthomonas arboricola pv. juglandis, were studied. different concentrations of nanoparticles were prepared on mueller hinton agar medium in two different ways in a com...
on- the-job training on of the most effective tools for managers to cope with the changing organizational environment. it grantess suitable services to customers, particularly in public service enterprises. if such training os goal oriented, planned systematically, and tailored to the employees, job content, then not only it could increase employees and organizational performance, but also it c...
Background & Aims: Hepatocellular carcinoma remains often refractory to classic therapies. Therefore, the search for new natural compounds with minimal toxicity is of particular interest in treatment of liver cancer. In this context, it has been shown that 2-methyl-3-pentyl-6-methoxyprodiginine isolated from cell wall of Serratia marcescens has powerful growth inhibitory effects against di...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
Endogenous mammalian lectin-like sugar-binding molecules have been previously described that have immunoregulatory properties. Further, the addition of defined simple saccharides to lymphocyte cultures has been shown to inhibit a variety of in vitro lymphocyte functions, presumably because these sugars are able to compete with the binding of endogenous lectins to critical membrane receptors. In...
Xanthine oxidase (XO) plays an important role in purine degradation humans. The study aimed to determine the XO inhibitory potential of Chrysanthemum morifolium dried flower ethyl acetate sub-fractions and its anti-hyperuricemic effect rat models. Bioassay-guided fractionation based on assay was employed obtain bioactive fractions sub-fractions. In vitro cytotoxicity cellular antioxidant capaci...
A series of mono-pyrrolo[2,3-d]pyrimidines 4a-4k, unsymmetrical bis-purine isosteres 5a-5e and symmetrical bis-pyrrolo[2,3-d]pyrimidines 6a and 6b connected via di(1,2,3-triazolyl)phenyl linker were synthesized by click chemistry. Whereas mono- 4g and bis-pseudopurine 5e showed selective inhibitory activities on cervical carcinoma (HeLa) cells, bis-pyrrolo[2,3-d]pyrimidine 6b exhibited potent a...
Cytotoxic effects investigation of nanomicelle and free curcuminoids against cancer and normal cells
Abstract Curcumin, which is derived from the turmeric rhizomes (curcuma longa) as a natural polyphenol, is a substantially lipophilic molecule. This commonly used substance is employed as a spice and coloring agent in food and contains potent antioxidant, as well as anti-inflammatory, and anti-proliferative tumor activities. The developed nanomicelle formulations of curcumin are used to ...
To apply human mesenchymal stem cells (hMSC) to regenerative medicines, it is necessary to multiply hMSC in vitro in a short period. In addition, it is desirable that the medium which is used for the hMSC multiplication is not supplemented with the serum, because the addition of the serum has risks of infection. In this study, we cultured hMSC with three kinds of medium used for multiplying hMS...
