background: various mtt assay methods are proposed to obtain the cell sur- vival parameters. objective: determining the survival curve characteristics of two cancerous cells of interest based on a common and a novel mtt assay method after exposing them to ionizing radiation. method: a common and a novel mtt assay method were used and compared for obtaining the f10b16 melanoma and 4t1 breast ade...

Warts are little lumps growing in the skin. You might have had a wart or know them from children’s books, typically on witches’ noses. quite common children. Did you ever wonder where they come from? be surprised to learn that warts caused by virus. Viruses germs need cells multiply themselves. Cells building blocks of all living things. The virus causes warts, called human papillomavirus, infe...

background: limited resources for adult stem cells necessitate their in vitro culture prior to clinical use. investigating mitochondrial dna (mtdna) and telomere shortening has proved to be important indications of stem cell validity. this study was designed to investigate these indicators in multiple passages of three adult stem cell lines which were produced in our stem cell laboratory. metho...

oral lichen planus is diagnosed according to clinical and histopathological characteristics.some times all of the classical  histopathological features can not be seen.in some articles the presence of mast cells have been noted below the epithelium of oral lichen planus patients.the following study was done to evaluate the number of mast cells in the histopathological sections of 20 oral lichen...

objective: in peripheral blood polymorphonuclear and mononuclear cells nitric oxide (no) could be synthesized by an enzyme called inducible no synthase (inos). inos gene (nos2a) is located on chromosome 17 at position 17q11.2-q12. no is released during inflammatory responses. in the present studies the frequency of nos2a gene polymorphisms and their effects on no production were investigated in...

Objectives: During the past decades, cosmetic surgery has become increasingly popular.

Methods: In the present study, 150 special need people in cosmetic clinics were randomly assigned to fill questionnaires for assessing body area concerns. Resul...

Introduction: One of the vital enzymes during spermatogenesis, which is one of the pluripotency factors of stem cells and contributes to maintaining their pluripotency is alkaline phosphatase. ZBTB16 and ZFP proteins are critical elements in stem cells which are expressed in pluripotent stem cells and maintain their pluripotency due to their role in messaging pathways. Material & Methods: The ...
