background & aim: ocimum basilicum l. is belong to the lamiaceae family which is cultivated as a culinary, industrial and medicinal plants in some countries from thousands years ago. the seed of this plant is rich in poly un-saturated fatty acids (pufa) and produced a large amount of mucilage. experimental: the oil of seed was extracted separately and converted to fatty acids methyl esters...

The present study aimed to investigate the effects of 17β-estradiol and tamoxifen, an agonist and inhibitor of the estrogen receptor (ER), respectively, on the proliferation and apoptosis of gastric cancer cells, as well as the messenger (m)RNA expression levels of ER-α36. Nested reverse transcription-polymerase chain reaction (RT-PCR) confirmed that ER-α36 was expressed in the BGC823, MKN45 an...

Background—Blood lead levels above 0.48 mol/L (10 g/dL) in adults have been associated with increased risk of cardiovascular, cancer, and all-cause mortality. The objective of the present study was to determine the association between blood lead levels below 0.48 mol/L and mortality in the general US population. Methods and Results—Blood lead levels were measured in a nationally representative ...

kinetic study of epoxidation of unsaturated ketone of mesityl oxide was studied by usinghydrogen peroxide in the presence of dodecyltrimethyl ammonium bromide (dtab) as aninverse phase transfer catalyst. the reaction was carried out in the two-phase media of waterheptanewith 1:1 ratio in 25 °c. it was found that the order of reaction for mesityl oxide forketone concentration in the range of 0.0...

888 CLINICALCHEMISTRY, Vol. 35, No. 5, 1989 Technical Briefs (-300 words text) summarize findings that are of interest to a relatively limited audience. Readers desiring fuller details may obtain them by writing directly to the author(s) at the address given. with normal zinc concentrations in urine ± 3.5 niol/L (6)], addition of 1.24 pmol of zinc per literfrom the catheter would cause an error...

A análise turbidimétrica e nefelométrica sequencial (STN) para duas aplicações analíticas empregando um nefelômetro e turbidímetro microcontrolado portátil (PMTN) é proposta. O PMTN é constituído de diodos emissores de luz, fotodiodos, microcontrolador como unidade de processamento central (CPU) e um um LCD (liquid crystal display) como amostrador. Os métodos STN foram aplicados para a determin...

A redução eletroquímica do Furoato de Diloxanida (FD) em acetonitrila sobre um eletrodo de carbono vítreo foi estudada neste trabalho. Foi observado que o FD é reduzido após uma transferência reversível de um elétron seguida por uma reação química irreversível, diagnosticada, como uma ruptura de uma ligação C-Cl. A redução do FD foi estudada por voltametria de varredura linear (LSV), pulso dife...
