3-(2’-n-butylbenzofuran-3’-yl)-5-aryl-4, 5-dihydro-1H-pyrazoles (4a-4k) have been synthesized. The synthesized products have been assayed for their antimicrobial activity against Gram+ve,      Gram-ve bacteria and fungi. All the synthesized products were assigned with IR, 1HNMR, Mass Spectra, TLC, and elemental analysis. Some of the products showed moderate activi...

Following the ban of synthetic antibiotics as antimicrobial agents and growth promoters, poultry nutritionists are now trying to find antibiotic substitutes. Agro-industrial by-products are abundant in tropical countries and have been used as the alternatives to conventional feedstuffs in poultry rations. These by-products are also known to contain several bioactive compounds such as oligosacch...

Some disinfectants have been demonstrated to be effective against surface mold growth and/or viruses responsible for the spread of common respiratory infections. Antimicrobial efficacy of green cleaning products has generally not been established in these areas. In this survey, the author found that out of 27 products approved by Green Seal as hard surface cleaners, 26 do not claim antimicrobia...

Oral diseases continue to be a major health issue worldwide. These are including oral and pharyngeal cancers and oral soft and hard tissue lesions, orofacial disorders, tooth loss, dental caries and periodontal diseases. These diseases are among the most important oral health problems. Also some of them cause significant health concerns. Despite general progress in the general health status of ...

Antimicrobial activity in some lichens from south Spain has been studied. Some lichenical substances are also identified. The structures of all compounds were elucidated by physical, spectral and chemical methods. A very high activity against Gram-positive bacteria has been observed in lichens containing usnic acid.

Introduction Iodine and iodinated resin have been evaluated for water treatment. Iodine (2.5-7.0 mg/l water) has been used in water treatment since 1900, especially for troops. Iodine’s solubility in water depends on temperature (0.29 g/1 at 20°C, 0.78 g/l at 50°C and 4.45 g/1 at 100°C). Its hydrolysis and hence speciation in water depends on pH and concentration of titrable iodine in solution....
