Rheum ribes is among the Polygonaceae family which is endemic in Iran and a few neighboring countries. In this investigation, antibacterial effects of root, stalk and leaves extracts of Rheum ribes on a few common clinical isolates of gram negative pathogens were studied, using the cup plate and paper disc methods. Gram negative microorganisms studied were Escherichia coli, Klebsiella pneumonia...

The two distinct tearing mechanisms observed in ductile metal plates are the void-by-void advance of crack tip, and simultaneous interaction multiple voids on plane ahead tip. Void-by-void advance, which leads to a cup-cup surface morphology, is dominant mechanism if plate contains low number small void nucleation sites (i.e., second phase particles). Conversely, large and/or size trigger resul...

3563 Background: Molecular tumor profile assays (MTP) may predict the primary site of origin in CUP, but the impact of site-specific therapy on outcomes is undefined. Accurate identification of CUP patients (pts) with a colorectal site of origin would be expected to improve treatment results by directing the use of colorectal cancer regimens rather than empiric CUP regimens. METHODS We identi...

OBJECTIVES Belonging to Papaveraceae family, Glaucium vitellinum is one of the Persian endemic plants which has not been investigated biologically. The present paper focused on the assessment of the antibacterial and antifungal activities of the total methanol extract and alkaloid sub-fraction of the flowering aerial parts of G. vitellinum. MATERIALS AND METHODS The antibacterial and antifung...

A pyrimidne nucleobase, 5-phenylthio-2,4-bisbenzyloxypyrimidine and its analogs were synthesized and scanned for in vitro antifungal activity using cup-plate and macrobroth dilution method against Candida albicans, Aspergillus niger, Aspergillus flavus and Aspergllus fumigatus. In the cup-plate method, 5-phenylthio-2,4-bisbenzyloxypyrimidine showed very good antifungal activity compared to clot...

BACKGROUND The Cupressaceae are an important cause of pollinosis, particularly in Mediterranean countries. Cypress pollen allergenic extracts are difficult to produce since they have a low protein and a high carbohydrate content and consequently accurate standardization of these extracts is essential for diagnosis and immunotherapy. METHOD Natural Cup s 1 was purified by a combination of hydr...
