Introduction: Staphylococcus aureus is a gram positive bacteria responsible by localized and systemic infections. The bacterial resistance to antibiotics is a huge problem and a challenge for the development of new therapeutic modalities [1]. The photodynamic inactivation of microorganisms (PDI) is a promising technique to fight localized infections based on a association of a photosensitizer (...

Photosensitizers (PSs) in photodynamic therapy (PDT) are, in most cases, administered systemically with preferential accumulation in malignant tissues; however, exposure of non-malignant tissues to PS may also be clinically relevant, when PS molecules affect the pro-apoptotic cascade without illumination. Hypericin (Hyp) as PS and its derivatives have long been studied, regarding their photodyn...

as in iranian traditional medicine, bee venom (bv) is a promising treatment for the rheumatoid arthritis (ra) which is considered as a problematic human chronic inflammatory disease in the present time. smoking is considered to be a major risk factor in ra onset and severity. the main aim of this study is to investigate the effects of bv on cigarette smoke-induced inflammatory response in fibro...

Rheumatoid arthritis (RA) is an autoimmune disease characterized by proliferative synovial tissue. We used mRNA differential display and library subtraction to compare mRNA expression in RA and osteoarthritis (OA) synoviocytes. We initially compared the mRNA expression patterns in 1 female RA and 1 OA synovia and found a differentially expressed 350 bp transcript in the RA synoviocytes which wa...

Background: Adipose-derived stem cells (ADSCs) are a population of pluripotent cells used for tissue engineering purposes. The main purpose of the present study was to transdifferentiate the ADSCs to Schwann-like cells and to determine the intensity of apoptosis in ADSCs during the transdifferentiation process. Methods: ADSCs were isolated from the inguinal adipose tissue of adult rats and the ...
