a variety of group 4 metal catalytic systems (c2-symmetric {ebthi}-, {sbi}-type zirconocene complexes (c2-1–4); c1-symmetric (c1-5–8) and cs-symmetric (cs-9) {cp/flu}-type zirconocene complexes; cp*2zrcl2 (cp* 2-10)), half-metallocene complexes (cpticl3, hm-11), constrained-geometry (cgc-12) titanium catalysts) and post-metallocene catalysts (dow’s ortho-metallated amido-pyridino hafnium comple...

brassinosteroids are phytohormones possessing a wide spectrum of antistress activity. to seewhether this hormone is able to ameliorate the effects of water stress, the effects of 24-epibrassinolise onplant growth, accumulation of osmolytes (proline, sugars and ions), lipid peroxidation and electrolyte leakagewere investigated in colza (brassica napus l. cv. fusia) plants which were under water ...

background: due to interesting tumor imaging properties of bis-thiosemicarbazones, [103pd]-di-acetyl-bis (n4-methylthiosemicarbazone) ([103pd] atsm2) was prepared according to the analogy of radio copper homologues. materials and methods: palladium-103 (t1/2=16.96 d) was produced via the 103rh (p,n) 103pd nuclear reaction with proton energy 18 mev. the final activity was eluted in form of pd (n...

multiple sclerosis (ms) is an autoimmune disease characterized by recurrent episodes of demyelination and axonal lesion mediated by cd4+ t cells with a proinflammatory t helper (th)1 and th17 phenotypes, macrophages, and soluble inflammatory mediators. the overactive  pro-inflammatory  th1  cells  and  clonal  expansion  of  b  cells  initiate  an inflammatory cascade with several cellular and ...

introduction: nowadays various bone pain palliative therapeutic agents have been developed for bone metastases. among those, 153sm-ethylenediamine tetramethylene phosphonic acid (153sm-edtmp) is the major therapeutic agent which is widely used in the world. in this study, production, quality control and biodistribution studies of this therapeutic radiopharmaceutical have been presented and foll...

background: salvia limbata is an aromatic herbaceous plant and grows widely in iran turkey and afghanistan. in the previous study, six flavones together with rosmarinic acid were isolated from the ethyl acetate and methanol extracts of s. limbata. in this report, we focused on the isolation and identification of the glycosylated sterols and the main accumulated amino acid of the species s. limb...

background: determination of the impact of angiogenesis on tumor development and progression is essential. this study aimed to determine the serum levels of vascular endothelial growth factor (vegf) and interleukin 6 (il-6) in breast carcinoma, and to correlate them with tumor size, lymph node involvement, and cancer stage. methods: under aseptic precautions 5 ml of venous blood was collected f...

objective: the objective of this study was to investigate inhibition and anti-cancer effects of linoleic acid on the mcf-7 and mda-mb-231 human breast cancer cells. materials and methods: cell lines human breast cancer mcf-7 (gdc055) and mda-mb-231 (htb-26) cell lines were obtained from atcc. mcf-7 estrogen receptor positive human breast cancer cell line and  the estrogen receptor negative huma...
