background: all aerobically growing organisms suffer from exposure to oxidative stress, caused by partially reduced forms of molecular oxygen, known as reactive oxygen species (ros). these are highly reactive and capable of damaging cellular constituents such as dna, lipids and proteins. consequently, cells from many different organisms have evolved mechanisms to protect their components agains...
Background: Pseudomonas aeruginosa is an opportunistic pathogen and one of the important factors of hospital infection. It causes many issues such as urinary tract infections, respiratory infection in cystic fibrosis patients, and wound infection in burn patients, septicemia and meningitis. Antibiotic resistance through various mechanisms is one of the challenges for the treatment of pseudomona...
Abstract Background and Objective: The prevalence of different bacterial species and antibiotic resistance varies according to geographical conditions. Hence, we aimed to identify the prevalence of bacterial agents isolated from the urine culture and also investigate the antibiotic susceptibility of bacteria. Material and Methods: This cross-sectional study conducted on 7200 urine samples to id...
This study examined the effects of a commercial Lactobacillus probiotic on growth, survival and resistance of western white shrimp (Litopenaeus vannamei) larvae against salinity and formalin stresses in the Persian Gulf and Oman Sea Ecology Research Center. In this experiment, larvae were fed 6 times a day from mysis I (M1) step to post larvae 5 over 3 treatments including a control treatment C...
emerging new medications in the treatment of hbv produces hope and promises for curing of hbv. over the past decade, the development of oral nucleoside/nucleotide analogs (nas) with favorable potencies and tolerabilities has led to substantial advances in chronic hepatitis b (chb) therapy. the oral anti-hbv agents currently approved are lamivudine, adefovir dipivoxil , entecavir , telbivudine, ...
In this study carburizing and boronizing processes were applied to powder metallurgy steel specimens and the mechanical and tribological properties of the substrate and coatings were evaluated under various process conditions. The specimens, made from industrial test pieces, were carburized in a powder pack for a duration of 2-5 hrs at 850-950 ˚C. Similar specimens were pack boronized for 4 hr...
