A series of new quinazoline derivatives has been recently reported as potent multi-acting histone deacetylase (HDAC), epidermal growth factor receptor (EGFR), and human epidermal growth factor receptor 2 (HER2) inhibitors. HER2 is one of the major targets for the treatment of breast cancer and other carcinomas. Three-dimensional structure-activity(More)
Human keratinocytes could be used in the repair of damaged skin, in tissue engineering applications, gene therapy and recently, the generation of iPS cells. We isolated human keratinocytes from foreskin and subsequently cultured them on fibronectin, collagen type I, gelatin and laminin-coated dishes that contained three different types of serum-free medium(More)
Background: Chronic obstructive pulmonary disease (COPD) is a major public health problem that needs greater attention. Variability in the susceptibility to develop COPD is related to both genetic and environmental factors. Oxidative stress and inflammation are the major hallmarks of COPD and antioxidant status can be used as a biomarker to assess the risk(More)
Embryonic stem (ES) cell-derived hepatocytes have the potential to be used for basic research, regenerative medicine, and drug discovery. Recent reports demonstrated that in addition to conventional differentiation inducers such as chemical compounds and cytokines, overexpression of lineage-specific transcription factors could induce ES cells to(More)
BACKGROUND Over the past several years, mammals have been successfully cloned by either the splitting of an early stage embryo or nuclear transfer of adult somatic cells (NT) into oocytes. Although it has been 15 years since the generation of the first cloned mammals from somatic cells by NT, the success rate for producing live offspring by this technique(More)
BACKGROUND The balance between reactive oxygen species production and antioxidant activity has an important role in oxidative stress associated diseases such as phenylketonuria (PKU). We aimed in this study to evaluate the possible association between oxidative balance and clinical features of PKU patients. METHODS Twenty patients and 50 healthy subjects(More)
Resistance to antibiotics in bacteria, is one of the major problems of mankind. Each year, a large number of patients due to infection, lose their lives. One of the main mechanisms of antibiotic resistance is beta-lactamase secretion. This enzyme hydrolyzes the amide bond of a lactam ring in beta-lactam antibiotics. Bacillus licheniformis is a mesophilic(More)
MicroRNAs (miRNAs) are small regulatory molecules that negatively regulate gene expression by base-pairing with their target mRNAs. miRNAs have contribute significantly to cancer biology and recent studies have demonstrated the oncogenic or tumor-suppressing role in cancer cells. In many tumors up-regulation miRNAs has been reported especially miR-222 has(More)
