metalloporphirins; cu(tpp), mn(tpp)cl, co(tpp), fe(tpp)cl, zn(tpp) and mn(obp)cl catalyze region and chemoselective silylation of hydroxyl groups with hmds. fe(tpp)cl is the most effective catalyst and silylation occurs immediately in its presence at room temperature.

background: previous studies reported many discrepancies about the effects of corpus luteum (cl) and ovarian follicle size on the developmental competence of oocytes. objective: the aim of this study was to investigate the effects of cl and different size of follicle on the developmental potential of bovine oocytes. materials and methods: after ovarian classification based on presence or absenc...

abstract a simple and sensitive chemiluminescence (cl) method was developed for direct quantification of oxymorphone, a µ opioid agonist that is approximately 10 times more potent than morphine. in this method potassium permanganate in polyphosphoric acid was used as cl reagent. using this method, oxymorphone can be determined over the concentration ranges 13.5-337.8 ng ml-1 and 0.34-6.76 µg ml...

background: the prevalence of anti-neutrophil cytoplasmic antibodies (ancas) and anti-cardiolipin antibodies (anti-cl ab) in behcet’s disease (bd) and also their roles in vascular involvement is controversial. objective: to assess the prevalence of ancas and anti-cl ab as well as their correlations with clinical manifestations in iranian patients with bd. methods: in this case/control study, th...

background: cutaneous leishmaniasis (cl) is a major health problem in many parts of iran, although diagnosis of cl especially in the endemic area is easy, but treatment and management of the disease is a global dilemma. diag-nosis of cl in non-endemic area is not as simple as in endemic foci. in this study, the status and the proportions of cl induced by leishmania major and l. tropica among cl...

The synthesis, spectroscopy and magnetic characterization of five new dinuclear copper(II) complexes are described. All five compounds have the general formula [Cu2(L)4(O-R)2](Cl)2 or [Cu2(L)2(Cl)2](Cl)2, in which R = CH3 or H, L=2, 3 or 4-pyridinemethanol as L2, L3 or L4, respectively. The title compounds consist of dinuclear units with bridging methoxo groups in [Cu2(L4)4(O-CH3)2](Cl)2, hydro...

background: this study was conducted to explain the trend of cutaneous leishmaniasis (cl) in kermanshah province, western iran from 1991- 2012. methods: in this analytical-descriptive study, all of the patients suspected to cl in kermanshah province were studied. smears were prepared from most of them, stained with giemsa, and examined microscopically for leishman bodies. a few of the patients ...

background: cutaneous leishmaniasis (cl) is one of the most important health problems in different regions of iran that occurs both in zoonotic and anthroponotic forms in different foci of iran. the khuzistan province, located in the south west of iran in vicinity of the persian gulf, is one of the oldest susceptible foci for cl in iran. objectives: due to the lack of information about the cond...
