Pacemaking areas in the early embryonic chick hearts were quantitatively assessed using simultaneous multiple-site optical recordings of spontaneous action potentials. The measuring system with a 10- X 10- or a 12 X 12-element photodiode array had a spatial resolution of 15-30 microns. Spontaneous action potential-related optical signals were recorded simultaneously from multiple contiguous reg...

Objective(s) This study planned to assess the value of PCR IS6110 assay in tissue specimens of needle pleural biopsy in patients suspicious to pleural tuberculosis. Materials and Methods Sixty eight patients with lymphocytic exudative pleural effusion underwent pleural biopsy. Tissue samples were sent for pathologic examination and PCR IS6110 assay. The results of PCR reported as positive/ nega...

The effects of three Ficus carica leaf extracts on the total cholesterol levels (TC) of serum and liver were investigated in experimentally-induced nutritional hyperlipidemic rats. In nine treatment groups (n=5 each group), hyperlipidemic rats were treated daily with hydromethanolic (total) extract (2.5, 5, 10 mg/kg, intraperitoneal [ip]) and its aqueous fractions, namely fraction A (10, 50, 25...

A 24 hour gastric aspiration study was carried out on nine Polya gastrectomy, eight pernicious anaemia, and nine matched control subjects. Intragastric pH, bacteria, nitrite, and N-nitroso compounds were assessed half hourly whilst ambulant and hourly when in bed. Both total and nitrate reducing bacterial counts were positively related to pH (chi 2 = 279.3; p less than 0.001), as was nitrite co...

abstract: evaluation of drought tolerance for 20 barley genotypes were conducted under normal irrigation and terminal stress condition by withholding irrigation at the time of 50% flowering. drought effect on grain yield and plant total mass traits was studied and eight of stress indices including stress tolerance index (sti), stress tolerance (tol), stress susceptibility index (ssi), mean prod...

Sporotrichosis is a chronic subcutaneous fungal infection with global distribution. It is a rare fungal infection with nine reported cases in Iran, including eight humans and one animal, within the past 30 years. Among the human cases, seven were of the fixed cutaneous type of sporotrichosis and one had sporotrichoid lymphocutaneous. The reported patients were within the age range of 23-60 year...
