امروزه شهرها به عنوان یک سامانه، نیازمند مدیریت می باشند که به تعیین اهداف و برنامه پرداخته و فعالیت عناصر مختلف شهری را هماهنگ نماید. از این رو هدف اصلی در این پژوهش تعیین وضعیت مدیریت شهری در ساماندهی خدمات شهری منطقه 5 شهر کرمانشاه می باشد. روش پژوهش توصیفی- تحلیلی است و نحوه جمع آوری اطلاعات به صورت پیمایشی و استفاده از پرسشنامه محقق ساخته بوده که براساس فرمول کوکران حجم نمونه 320 نفر محاسب...
In severe human beta-thalassemia, the pathophysiology relates to accumulation of excess alpha-globin chains at the membrane. One hypothesis is that membrane-associated alpha-globin by virtue of it's iron or hemichromes produces oxidation of adjacent membrane proteins. The availability of a mouse model of severe beta-thalassemia, as well as a transgenic (thalassemic-sickle) mouse that expresses ...
The analysis of beta-carotene and lycopene, the two predominant carotenoids in human serum and tissues, was extended to the level of geometrical (cis-trans) isomers by using an improved reversed-phase HPLC methodology. We separated five geometrical isomers of beta-carotene and seven of lycopene in human serum and tissues. 13-cis-beta-Carotene was identified as the predominant cisisomer in human...
Nowadays, the separation of pistachios which seem to have aflatoxin is done according to their organoleptic physical qualities like color and etc. As these methods are not fully practical, and there is always a possibility of error and also the conditions like the wrong time harvest, the transportation of picked pistachios, the delay on the processing cause some contaminations in pistachios wh...
We have characterized the production of transforming growth factor (TGF) activities by five human breast cancer cell lines in culture. The presence of TGF-alpha and -beta activity in medium conditioned by these cells was detected by induction of anchorage-independent colony formation of normal rat kidney cells in soft agar and by epidermal growth factor and TGF-beta receptor competition studies...
We investigated the reason for the inability of lipopolysaccharide (LPS)-resistant (Lps-defective [Lps(d)]) C57BL/10ScCr mice to produce beta interferon (IFN-beta) when stimulated with bacteria. For this purpose, the IFN-beta and other macrophage cytokine responses induced by LPS and several killed gram-negative and gram-positive bacteria in LPS-sensitive (Lps-normal [Lps(n)]; C57BL/10ScSn and ...
Background: Carotenoids are pigments with important physiological effects in the human body that are involved in strengthening the immune system and reducing the risk of many diseases, including cancer. Objective: With regard to the importance of these substances and the high content of them in carrots (Daucus carota L.), and in order to identify the most suitable geographical area for obtainin...
Salvia limbata .C. A. Mey is a herbaceous perennial plant whit proven medical effects, belongs to the family Lamiaceae. The objective of this study is to investigate the quantitative and qualitative variability of the essential oil of this species cultivated in new conditions (Karaj and Abhar) Compared with wild population (Semnan). The aerial parts of the plants were collected at the flowering...
Titanium-stabilized Zirconia (ZrO2:Ti) nanoparticles were synthesized by the solution combustion synthesis method. This functional method is used for production of luminescent materials. Ti concentration was between 0.1 to 2 mol %. Nano crystalline tablets of 5 mm diameter and 1 mm thickness were prepared from synthesized powder. The effects of Ti concentration and annealing temperature on the ...
Anethum graveolens L. is a mediterranean plant which its essential oil have been used in medicine, food and costemic industeries. In this study the effects of water stress on quantity and quality of essential oil were investigated. The five drougth treatment inclded 0 (control), 80%, 60%, 40%, 20% field capaciry were used. The results showed that the most content (0.50% w/v) of essential oil ...
