objective(s): adeno-associated virus type 2 (aav2) vectors are widely used for both experimental and clinical gene therapy. a recent research has shown that the performance of these vectors can be greatly improved by substitution of specific surface-exposed tyrosine residues with phenylalanines. in this study, a fast and simple method is presented to generate aav2 vector helper plasmids encodin...

background:breast cancer remains the most common and second lethal cancer in females. her-2/neu is one of the most important amplified oncogene in breast cancer. the amplification of her-2 is correlated with decreased survival, metastasis, and early recurrence.  the amplification of her-2/neu gene and synthesis of the protein are reported in 10%-34% of breast cancer cases associated with tumor ...

the present study was conducted to test the effect of origanum majoranum extract (ome) of leaves on alterations induced in a model of type 2 diabetic rats. adult male wistar rats were fed high fat diet for 3 weeks and injected a single dose of streptozotocin (35 mg/kg) intraperitoneally to induce type 2 diabetic rats. diabetic rats were given aqueous extract of ome in a dose of 20 mg/kg orally ...

       The anti-apoptotic gene bcl-2 is located in mitochondria, but it is uncertain whether its expression affects hepatocyte survival in ischemia/reperfusion (I/R) injury. This experiment was designed to evaluate the role of folic acid in expression of bcl-2 in I/R in rat liver. Eighteen Wister rats were divided into sham-operated controlgroup (C) (n=6), I/R group (...

crouzon syndrome is a rare autosomal dominant premature cranyosynostosis, caused by fibroblast growth factor receptor 2 gene mutation on chromosome 10. the predominant skull and facial malformations with potential compromise airway make the crouzon syndrome a demanding issue for anesthesiologists and surgeons, required dynamic team work. in this report we describe a child, a known case of crouz...

background and objective: clinical behavior of basal cell carcinoma (bcc) is known to be different according to histological growth pattern and basosquamous cell carcinomas (bsc) are known with their aggressive behavior and metastatic capacity. in this study, we evaluated bcl-2 and cyclin d1 expressions in bcc and bsc cases comparatively, to explore their predictive value on the aggressive beha...

b a ckground:  the purpose of our study was to investigate the possible effect of  bsm i vitamin d receptor (vdr’s) polymorphism on changes of the inflammatory and oxidative stress (os) biomarkers in response to daily intake of vitamin d- fortified yogurt drink ( doogh ) in subjects with type 2 diabetes (t2d). m ethods : in a randomized controlled trial, 100 t2d subjects were allocated to two g...

objective(s):n-myc downstream regulated gene 2 (ndrg2) is a candidate gene for tumor suppression. the expression of ndrg2 is down-regulated in several tumors including lung cancer. the aim of this study was to explore the effect of ndrg2 overexpression on invasion, migration, and enzymatic activity of matrix metalloproteinase-2 (mmp-2) and -9 (mmp-9) in human lung adenocarcinoma a549 cells.  ma...
