background and objectives: microbial spoilage of juices and industries related with alicyclobacillus are considerable international issues. this spore-forming bacterium causes changes in juices odor and taste. the isolation and identification of alicyclobacillus contamination in juice producing and packaging industries has an essential role in the prevention and control of this type of spoilage...

used in conjunction with or as a replacement for traditional methods, it is expected that specific laser technologies will become an essential component of contemporary dental practice over the next decade. the current review is designed to focus on the acid resistance of laser application and tries to introduce laser settings capable to achieve this feature for clinical application. applicatio...

background: enterobacteriaceae are a large group of bacteria widely distributed in nature. escherichia coli is the most com­mon cause of urinary tract infection. two amino acid substitutions, in gyra, are commonly responsible for quinolone re­sistance in e. coli . the aim of this study was molecular survey of nalidixic acid resistance e.coli isolated from patients in the codones of 83 and 87 gy...

background and objectives: typhoid is a major health problem faced by the developing countries like pakistan. more than 20 million cases are reported annually worldwide. currently fluoroquinolones are the drugs of choice to treat typhoid fever. in vivo resistance to fluoroquinolones leading to therapeutic failure is developing rapidly and is becoming a major concern for the clinicians. the obje...

diet as a part of lifestyle plays a pivotal role in the development of metabolic syndrome and its consequences. fatty acid composition as a part of dietary intake affects blood fatty acid concentrations, insulin sensitivity and different metabolic pathways associated with the occurrence and consequences of the metabolic syndrome. the aim of this review is to evaluate the effects of dietary fatt...

a total of 385 urine specimens from suspected urinary tract infections were subjected to bacteriological analysis and susceptibility testing at a major university hospital laboratory in tehran. a battery of eight beta-iactam antibiotics, commonly prescribed in iran, and three third-generation cephalosporins (ceftazidime, ceftriaxone and ceftizoxime) that are usually reserved for limited use in ...

background: considering the increasing trend of obesity, especially in developing countries such as iran, and the role of inflammatory factors and insulin resistance (ir) in the occurrence of obesity?related complications as well as the safety of some agents such as folic acid and metformin, this clinical trial was designed to investigate the effect of metformin and folic acid on inflammatory f...

Drought affects yield of peanut, but its effect on oleic and linoleic acids that influence its oil quality of peanut genotypes with different levels of drought resistance has not been clearly investigated. Therefore, the aims of this research were to determine whether soil water levels could affect oil quality by changes in fatty acid compositions of peanut, and to investigate the changes i...

phenolic resins are synthetic low molecular weight thermoset resins which are polymerized and cured to higher molecular weights by condensation method. these resins have high weathering resistance, high oxidative thermal properties and good chemical resistance. phenolic resins can be cured thermally or by acid curing. the most common method of curing phenolic resin is by thermal curing that tak...

galbanic acid, a sesquiterpene coumarin from ferula szowitsiana , and conferol, another sesquiterpene coumarin from f. badrakema , were evaluated for their effects on the reversal of multi-drug resistance in clinical isolates of staphylococcus aureus and escherichia coli , respectively. neither galbanic acid (up to 1000 μg/ml) nor conferol (up to 400 μg/ml) by itself shows any antibacterial act...
