background & aim: eucalyptus l'her. [an aromatic genera of the family (myrtaceae)] is native to australia and other tropical species is planted worldwide. the purpose of this study is to extract and identify the essential oils components of four species of eucalyptus l'her. cultivated in botanical garden of kashan, central iran. experimental: leaves of e. largiflorens, e. intertexta, ...

new blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ecs) which in turn give rise to primitive capillary network. human cord blood (hcb) contains large subsets of mononuclear cells (mncs) that can be differentiated into endothelial-like cells in vitro. human mononuclear progenitor cells were purified from fresh umb...

materials and methods: 32 new zealand rabbits were randomly divided into three groups: control group, high-cholesterol group and losartan group. the level of weights, serum lipid levels and inflammatory factors, such as il-6 and hs c-reactive protein were detected before the losartan intervention and two months after the losartan intervention respectively. the content of angii was detected on l...

achillea millefolium belong to the asteraceae family and from genus achillea. in this study essential oils were extracted from all aerial parts via hydro distillation (hd) method by clevenger set . by using of gas chromatography/mass spectrometry ( gc-ms) technique the chemicals component essential oil were identified. about 41 components with were identified which encompassed 97.66 percent of ...

hybrid-density functional theory (b3lyp/def2-tzvpp) based method and nbointerpretation were used to investigate the conformational behavior of 1,2-dihalodisilanes[halo=f (1), cl (2), br (3), i (4)]. the b3lyp/def2-tzvpp results showed that the anticonformations of compounds 1-4 are more stable than their corresponding gaucheconformations. the stability of the anti conformation compared to the g...

patients and methods in total, 98 samples in four groups (hiv-positive and hiv-negative persons with and without oc) were obtained from the oral cavities and cultured on sabouraud’s dextrose agar and chromagar. also blood samples were obtained to assess plasma level of ifn-γ, il-4, il-6 and il-17 using elisa technique. background cell-mediated immunity (cmi) by cd4 + th (t helper)-type cells is...

nanoparticles of coordination polymer [co2(pydc)2(h2o)6]n.2n h2o [h2pydc = pyridine-2,5-dicarboxylic acid] have been synthesized by sonochemical method and characterized by elemental analysis, infrared spectroscopy, powder x-ray diffraction, scanning electron microscopy, dls particle size analysis and tga/dta. the structure of single crystalline coordination polymer developed from nanosized coo...

abstract-a novel and efficient method has been developed for the synthesis of pyrano[3,2-c]quinoline-2,5-dione derivatives by the convenient ultrasound-mediated condensation of 4-hydroxyquinolin-2-one with meldrum’s acid and aldehydes in the presence of a catalytic amount of [hmim]hso4 as a green, efficient and reusable acidic ionic liquid medium. the stability of the ionic liquid during the re...
