background and objective: an outer membrane protein (omp) of helicobacter pylori namely oipa, is an important vir- ulence factor associated with peptic ulcer and gastric cancer risks. the purpose of this study was to isolate the 34 kda omp of h. pylori and evaluate its immunogenicity in experimental animals for rapid detection of more virulent h. pylori isolates. material and methods: sarcosine...

extremely low frequency (elf) and radio frequency (rf) electromagnetic field may affect biological systems by raising generation free radicals by decline activities of glutathione peroxidase dismutase or increase in the lifetime of free radicals with inhibited pretreatment of cells antioxidant like that alpha tocopherol. elf and  rf electromagnetic  field maycan damaged dna  with raising level ...

chronic obstructive pulmonary disease (copd) is a public health problem worldwide. increased energy and protein needs, decreased energy and protein intake are common in copd patients. adequate intake is essential to improve pulmonary function and immune system, prevention of weight loss and maintaining muscle mass and strength. assessment of energy and protein intake and its relationship with p...

background one disadvantage of expressing heterologous proteins in escherichia coli is that the proteins are frequently expressed as insoluble inclusion bodies. to avoid this problem, heterologous proteins are typically expressed as a fusion protein. maltose binding protein (mbp) is one of the widely used partners for production of recombinant fusion proteins in e. coli. mbp is among the most e...

background: diagnosis and treatment of neuropsychiatric lupus is still a major challenge in clinical practice. we investigated the association between depression and anti-ribosomal p (anti-p) antibodies in a sample of iranian patients with systemic lupus erythematosus (sle). materials and methods: th is cross-sectional study was conducted on adult patients with sle referring to a referral out-p...

materials and methods twelve natural compounds jaceosidin, withaferin a, curcumin, epigallocatechin-3-gallate (egcg), artemisinin, gingerol, ursolic acid, ferulic acid, berberin, silymarin, resveratrol, and indol-3-carbinol were docked against e6 and e7 oncoproteins of high-risk hpv types 16 and 18 using a protein-ligand docking software called autodock4.2. results out of these 12 natural compo...

background cucumber mosaic virus (cmv) has isometric particles with a diameter of about 28–29 nm. a useful method to recognize regions from mutagenesis in the coat protein (cp) gene are important for particle assembly and the expression of viral in cp expression systems like bacteria such as e.coli or yeast as well as their assembly into virus-like particles (vlp). objectives in this paper, we ...

the impact of pgf2? on total proteins, free amino acids and the amino transferases in the gonads of silkworm, bombyx mori l. were investigated in the present experiment. the effect of pgf2? resulted in increase in the total protein and free amino acid contents in the gonads of silkworm larvae indicating improved structural and dynamic levels of organization. the enhanced activity levels of amin...

purpose: to evaluate colostrum total protein differences between left and right breasts and between mothers of boy and girl infants. materials and methods: a cross sectional study for delivery was carried out on 30 boy-delivered and 30 girl-delivered mothers aged 16 to 36 years, conducted at the izadi and al-zahra hospitals in qom city, iran. colostrum was collected from both breasts by manual ...

The aim of this study is to investigate antibacterial effects of immunodominant proteins isolated from the venom of Naja Naja Oxiana snake against Staphylococcus aureus, Escherichia coli, Bacillus subtilis and Pseudomonas aeruginosa.The innate immune system is an important line of defense against bacterial diseases. Antibacterial proteins produced by snake venoms have recently attracted signifi...
