an efficient transformation system for the medicinal plant portulaca oleracea was established using agropine-type agrobacterium rhizogenes atcc15834. hairy roots were obtained directly from cotyledon leaves explants seven days after inoculation with the bacteria. the highest transformation efficiency was obtained from cotyledon leaves explants, and amounted to 53.3% within two weeks. roots grew...

anti-n-methyl-d-aspartate-receptor (nmda-r) encephalitis is a new autoimmune disorder, often paraneoplastic in nature, presenting with complex neuropsychiatric symptoms. diagnosed serologically, this disorder is often responsive to immunosuppressant treatment. we here in report the case of a 56-year-old man with anti nmda-r encephalitis presenting initially with disorientation and hallucination...

losartan potassium is a well known orally active non-peptide angiotensin ii receptor antagonist. losartan potassium and its principle active metabolites block the vasoconstrictor and aldosterone secreting effect of angiotensin ii by selectively blocking the binding of angiotensin ii to at1 receptors. the drug is reported to promote the decrease in ventricular hypertrophy, salt and water excreti...

a b s t r a c t introduction: mercury is the second most metal pollutant in the world and has the potential to induce many pathologic conditions, especially in nervous system, such as depression. here we tried to find out if nitric oxide has any possible role in the pathophysiology of depression induced by this metal. although the role of nitric oxide has been shown in mood control, here we use...

the 2-mono and 2,6-disubstituted methyl-1,4-dihydropyridines were synthesized by reaction of morpholine, thiophenol, 8-hydroxyquinoline, 2-naphthol and 2-mercopto-1-methyl imidazole with the 2-mono bromo and 2,6-dibromo-1,4-dihidropyridines.

A newly devised dual labeled iodine isotopic method is described for the detection and quantitation of alterations in thyroxine (T(4)) deiodination rate in man. This method employs the principle of a constant (125)I infusion to serve as a reference source for the generation of (131)I derived from the deiodination of T(4)-(131)I. Measurement of these two iodide isotopes are made in serially time...
