BACKGROUND One of the main challenges in skin flap surgery is tissue ischemia and following necrosis. The present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. METHODS Thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal rando...

 Nanotechnology presents countless opportunities to develop new and improved consumer products for the benefit of the society . A most prominent nanoproduct is nanosilver. Nanosilver particles are generally smaller than 100 nm and contain 20–15,000 silver atoms. Despite the wide application of nanomaterials, there is a serious lack of information concerning their impact on human health. In the ...

Background: Dorema aucheri (Apiaceae) grows in west and southwest of Iran. Young leaves of this plant are used orally as pickle or for cooking some local foods, as well as for the treatment of parasitic digestive infections and constipation. Objective: The aim of present study was evaluation of cytotoxic potential and total phenols determination of D. aucheri young aerial parts extract and fr...

OBJECTIVE This study was undertaken to investigate the role of the angiogenic factors vascular endothelial growth factor and basic fibroblast growth factor in the development and progression of Barrett esophagus and adenocarcinomas of the esophagus and gastroesophageal junction. METHODS Vascular endothelial growth factor and basic fibroblast growth factor messenger RNA expression levels, rela...

At least eight leukocyte interferon genes (IFL) and the single fibroblast interferon gene (IFF) have been located on chromosome 9 in humans. In somatic cell hybrids of human and mouse cells containing a normal complement of mouse parental cell chromosomes but reduced numbers of human chromosomes, the human leukocyte and fibroblast interferon DNA sequences were present only when human chromosome...

BACKGROUND Tendon injuries are common and it takes a long time for an injured tendon to heal. Adverse phenomena such as adhesion and rupture are associated with these injuries. Finding a method to reduce the time required for healing whichimproves the final outcome, will lead to decreased frequency and intensity of adverse consequences. This study was designed to investigate the effects ...

Tumor-associated fibroblasts are functionally and phenotypically distinct from normal fibroblasts that are not in the tumor microenvironment. Fibroblast activation protein is a 95 kDa cell surface glycoprotein expressed by tumor stromal fibroblasts, and has been shown to have dipeptidyl peptidase and collagenase activity. Site-directed mutagenesis at the catalytic site of fibroblast activation ...

objective: different techniques have been suggested for the repair of bone defects at the injured sites. use of biomembranes, or application of plasma rich in growth factor (prgf) at the site of proliferation of osteoblasts are among the suggested techniques. the current study aimed to compare the biocompatibility of human periodontal ligament fibroblasts (hplf) cultured on hypro-sorb f, perica...
