background and objectives: pseudomonas aeruginosa is one of the most important opportunistic pathogens in patients who suffer from immunodeficiency and burns. wound infections caused by p. aeruginosa can rapidly change to systemic and life threatening situation. the aim of this study was to apply florescent in situ hybridization (fish) method for rapid detection of p. aeruginosa in burrn patien...

background and purpose: salmonella is a group of enterobacterias that cause infectious diseases in human and animals. typhoid, bacteremia, enterocolitis and salmonellosis which are caused by this bacterium are considered major health concerns in developing countries, such as iran. quick, accurate, reliable and early diagnosis is vital to prevent salmonella outbreak. materials and methods: there...

we investigated the use of dna amplification by polymerase chain reaction (per) for detection of mycobacterium tuberculosis in 300 patients who were suspected of having pulmonary tuberculosis and compared the results with culture results which were performed in parallel with pcr. two-thirds of each sample was processed for smear and culture by standard methods and one-third was prepared for dna...

Nanostructured lipid carriers (NLC) are stable colloidal formulations with notable advantages for drug delivery systems. Thanks to their physicochemical stability, biocompatibility, biodegradability and controlled drug release, they have received increasing attention for the last several years. The aim of the study was to prepare and characterize nanostructured lipid carriers (NLC). Both, the e...

background: the ultrasonography probes are cleaned by absorbent soft, dry cloth. this question arose whether linear and convex ultrasound probes coupling with gel could perform as a means for nosocomial infections transmission, and which method is economical and more efficient for cleaning the probes. this study was conducted to answer these questions. methods: one hundred – ninety two patients...

In order to verify the effect of ultrasonic waves control invasion golden mussel, Limnoperna fortunei, three experiments were made with different numbers individuals and for each experiment sonicator device was using at 40kHz frequency. addition, tests varied in time days exposure mussels waves. As a result, several mortality decoupling analyzed samples noted, significant differences regarding ...

Gloriosa superba is a very important medicinal plant that is used for the treatment of diseases like Gout, arthritis, cancer and act as anthelmintic, antimitotic and antiabortive agent. Its tuber is a great source of Colchicine for the pharmaceutical industries and requires drying before extraction. The accelerated artificial drying technique using Microwave Vacuum oven was evaluated with other...

-carotene has been used for years as natural food colorants and in cosmetics and healthcare due to their antioxidant property. The production of -carotene by Mucor azygosporus was evaluated, utilizing deproteinized waste whey filtrate. Since pigments are intracellular, their extraction needed after cell cultivation. In this study, different strategies for extraction of -carotene from M. azyg...

A calcium protease which degrades neurofilaments was first observed in the fan worm Myxicola infundibulum and in the squid Loligo forbesi [l] and subsequently in a mammalian system [2,3]. Many of the polypeptides in Myxicola axoplasm are degradation products of the 160 000 and 150 000 M, polypeptides as has been shown by careful peptide mapping. Moreover, there is a high probability that they r...
