conclusions the results indicated that there was a positive association between susceptibility to chronic hbv infection and tnf-α polymorphism. in addition, hbv patients carrying -308 gg, -857 cc, and -863 aa genotypes with lower serum levels of tnf-α had an increased risk of infection. background the host genetic background regulates the natural history of chronic hepatitis b virus (hbv) infec...

background: the pro-inflammatory cytokine, tumor necrosis factor-alpha (tnf-α), is a pathogenic element for a number of disorders. previous studies have reported that the -1031 t/c and -238 g/a polymorphisms in the promoter region of the tnf-α gene are important factors in reproductive-related disorders. one of the most common gynecological diseases of women during the reproductive years is end...

introduction: inflammation and edema symptoms are physiological response to triggers that can be induced by different mediators such as cytokines. rheumatoid arthritis is the most common form of arthritis which is characterized by chronic inflammation of the synovial membrane, severe and debilitating pain and progressive cartilage injury. it is clear that cytokines are involved in different sta...

background and objective: recent studies have shown that not only the quantity, but also the quality of dietary fatty acids can affect lipid parameters. elaidic acid is a major hydrogenated by-product of vegetable oil play a role in the development of cardiovascular disease, especially atherosclerosis, through changing lipid profile and increase in inflammation and inflammatory factors. on the ...

objective(s): inflammation is an immune response toward injuries. although inflammation is healing response, but in some condition it will lead to chronic disease such as rheumatoid arthritis, inflammatory bowel disease, atherosclerosis, alzheimer’s and various cancer. indonesian cassia (cinnamomum burmanni c. nees & t. ness) known to contain coumarin, is widely used for alternative medicine es...

background: bone resorption is one of the main features of inflammatory periapical lesions and is mainly mediated by interleukin-1 beta (il-1β), tumor necrosis factoralpha (tnf-α) and prostaglandin-e2 (pge2). recent investigations of these lesions revealed that pharmacological modulation may be possible. objective: the aim of this study was to evaluate the effect of ibuprofen on il-1β, tnf-α an...

background: selenium (se) is part of the glutathione peroxidase enzyme complex (gsh-px) that plays an important role in antioxidant mechanisms in body, also it has been demonstrated that populations with low se intake have 2-3 times greater risk of ischemic heart disease. objective: to determine the circulating levels of il- 6, tnf-α, cu, zn, and se in patients with chronic coronary artery dise...
