BACKGROUND Several evidences indicate stimulation of peroxisome proliferator activated receptor γ (PPARg), promotes neuronal differentiation. This study was conducted to testify the prominence of PPARγ during neural differentiation of human embryonic stem cells (hESCs). METHODS PPARγ expression level was assessed during neural differentiation of hESCs.(More)
Esophageal squamous cell carcinoma (ESCC) is the second and third most common malignancy in Iranian males and females, respectively. Treatment of ESCC is largely ineffective due to lack of detection at early stages of the disease. In recent years, miRNA, a small RNA molecule, has drawn much attention to researchers as a potential biomarker for esophageal(More)
Docetaxel acts through the inhibition of tubulin polymerization and reduction in the expression of BCL-2 gene. In this study, nanoparticles containing Docetaxel were prepared and their effects on the gene expression levels of BCL-2 and BAX genes were investigated. The drug was first conjugated to chitosan, and the nanoparticles were assembled in the(More)
The p53 tumor-suppressor gene encodes a nuclear phosphoprotein with cancer- inhibiting properties. The most probable cancerous mutations occur as point mutations in exons 5 up to 8 of p53, as a base pair substitution that encompasses CUA and GAT sequences. As DNA drug design represents a direct genetic treatment of cancer, in the research reported(More)
BACKGROUND Nontypeable Haemophilus influenzae (NTHi) is a significant pathogen in children, causing otitis media, sinusitis, conjunctivitis, pneumonia, and occasionally invasive infections. Protein D (PD) belongs to the minor outer-membrane proteins of H. influenza. Moreover, it has been shown that this protein is one of the most potent vaccine candidates(More)
BACKGROUND Dermatophytosis is the most important superficial fungal infection which affects nearly 20% of human population worldwide. Recurrence of disease and emerging resistance of Trichophyton rubrum to synthetic antifungals are the main problems in control of dermatophytosis. The purpose of this study was to evaluate the effect of cold atmospheric(More)
Uterine leiomyomas are the most common gynecologic benign tumors of the female genital tract that cause a variety of health problems including, abnormal menstrual bleeding, pelvic pain, placenta displacement, premature labor, and miscarriages. Recently, studies showed that recurrent somatic mutations in MED12 exon 2 are the major cause of uterine leiomyomas(More)
Nanocomposites based on polyhydroxybutyrate (PHB) and hydroxyapatite (HAp) have recently been proposed for application in bone repair and regeneration, but very limited studies have investigated the effect of HAp on the rheological and thermal behavior of PHB. More important, the efficiency of a biomaterial depends greatly on its ability to interact with(More)
Formation of specific structures on poly-ɛ-caprolactone (PCL) and poly lactide-co-glycolide (PLGA) based electrospun mats is rationalized and the effect of interactive parameters; high voltage and flow rate on unique surface topography is evaluated. By increasing the collecting time in electrospinning process and enhancing fiber to fiber repulsion, surface(More)
The field of tissue engineering is an emerging discipline which applies the basic principles of life sciences and engineering to repair and restore living tissues and organs. The purpose of this study was to investigate the effect of cold and non-thermal plasma surface modification of poly (ϵ-caprolactone) (PCL) scaffolds on fibroblast cell behavior.(More)
