introduction: the correlation between right and left ventricular ejection fractions (rvef and lvef, respectively) has been studied in only a small number of patients with a marked decrease in rvef and lvef. the aim of the present study was to compare lvef and rvef in patients with ischemic heart disease. rvef and lvef were measured by cardiovascular magnetic resonance (cmr) imaging. materials a...
Ethyl acetate and chloroform extracts from aerial parts of Portulaca werdermannii and P. hirsutissima were tested in lymphoproliferation assays and axenic cultures of Leishmania amazonensis and Trypanosoma cruzi. Both extracts of P. werdermannii and P. hirsutissima had a potent inhibitory activity on lymphocyte proliferation. On the contrary, only the chloroformic extract of both plants inhibit...
The first general procedure for the synthesis of 5 to 7-membered 1-aryl-2-iminoazacycloalkanes is presented, by microwave-assisted ring closure of ω-arylaminonitriles promoted by polyphosphoric acid (PPA) esters. 1-Aryl-2-iminopyrrolidines were easily prepared from the acyclic precursors employing a chloroformic solution of ethyl polyphosphate (PPE). The use of trimethylsilyl polyphosphate (PPS...
The aim of this study was to investigate the effect of aerial parts of Stachys lavandulifolia Vahl. extract on the rat ileum contractions. The crude extract was prepared by maceration method (90% methanol) followed by fractionating into chloroform, ethyl acetate, petroleum ether and water. In adult male Wistar rats, ileum was sectioned and mounted in tissue bath and their contractility was reco...

During the last decade, shrimp aquaculture has developed rapidly in many developing countries. Antibiotic resistance is a major problem in shrimp aquaculture. Seaweeds are considered as potent source of bioactive compounds that are able to produce biological activities. The aim of this study was to evaluate the antibacterial activity of ethanolic and chloroformic crude extracts of the brown al...
This study assesses the antimicrobial effect of chloroformic extract of garlic (Allicin) on strains of mycobacterium tuberculosis. A standard H37RV isolate and isolates from patients with drug resistant pulmonary tuberculosis were used. A strain sensitive to 4 drugs (rifampin, &n...
