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...
The aim of the present study was to construct a fast-acting, eukaryotic expression vector in eukaryotic cells based on transmembrane-tumor necrosis factor‑α (TM‑TNF‑α) structure. Two types of recombinant eukaryotic expression vectors were constructed, pcDNA3.1-TM-enterokinase-TNF‑α and pcDNA3.1‑TM‑Factor Xa‑TNF‑α, according to the TNF‑α transmembrane segments. Following the generation of these ...
بررسی میزان سایتوکائین های التهابی در اشک چشم مصدومین شیمیایی مواجه یافته با گاز خردل با ضایعات چشمی
سولفور موستارد (بیس 2-کلرواتیل سولفید) sm,، از مواد شیمیایی آلکیله کننده تاول زاست که تاکنون بیشترین استفاده را به عنوان اسلحه شیمیایی داشته است. هدف از این مطالعه مقایسه میزان il-1β ,il-6,il-8 و tnf-α در اشک چشم افراد مواجهه یافته با گاز خردل در جنگ ایران و عراق که دارای خشکی چشم مزمن هستند با گروه شاهد می باشد. در این مطالعه 25 نفر از افراد مواجهه یافته با گاز خردل که دارای خشکی چشم مزمن بود...
BACKGROUND Major basic protein released from eosinophils to airway parasympathetic nerves blocks inhibitory M(2) muscarinic receptors on the parasympathetic nerves, increasing acetylcholine release and potentiating reflex bronchoconstriction. Recruitment of eosinophils to airway parasympathetic neurons requires neural expression of both intercellular adhesion molecular-1 (ICAM-1) and eotaxin. W...
Sakamoto, Tomohiro, Janet Woodcock-Mitchell, Kousuke Marutsuka, John J. Mitchell, Burton E. Sobel, and Satoshi Fujii. TNF-a and insulin, alone and synergistically, induce plasminogen activator inhibitor-1 expression in adipocytes. Am. J. Physiol. 276 (Cell Physiol. 45): C1391– C1397, 1999.—Obesity is associated with hyperinsulinemia and elevated concentrations of tumor necrosis factor-a (TNF-a)...
The effects of interleukin (IL)-8 on spontaneous IgE and IgG4 production in atopic patients were studied. IL-8 inhibited IgE and IgG4 production by purified surface (s) IgE+ and sIgG4+ B cells, respectively, while it had no effect on IgG1, IgG2, IgG3, IgM, IgA1, and IgA2 production by corresponding sIg+ B cells. The IL-8-induced inhibition was counteracted by IL-6 and tumor necrosis factor-alph...
Tumor necrosis factors (TNF; TNFA and TNFB) are major pro-inflammatory cytokines that are thought to be important in the pathogenesis of asthma. However, the functions of genetic polymorphisms in these cytokines have not been thoroughly examined in the context of asthma pathology. In an effort to discover polymorphism(s) in genes whose variant(s) have been implicated in asthma phenotypes, we ex...
Periodontitis is very prevalent worldwide and is one of the major causes of tooth loss in adults. About 80% of the worldwide population use medicinal plants for their health care. Stemodia maritima L. (S. maritima) antioxidant and antimicrobial effects in vitro as well as anti-inflammatory properties. Herein, the potential therapeutic effect of S. maritima was assessed in rats subjected to expe...
یافته های پژوهش : یافته های پژوهش نشان داد که غلظت tnf-? سرمی در گروه های سه گانه پس از 15 روز تمرین به طور معناداری کاهش پیدا کرد ، و لیکن غلظت 6- il تغییر معناداری نکرد.همچنین نتایج تحلیل واریانس بر پاسخ غلظت های 6- il و tnf-? سرمی در گروه های سه گانه پس از 15 روز تمرین و مصرف مکمل امگا-3 به ترتیب نشان می دهد ، که تفاوت معنی داری در 6- il فقط بین گروه اول و دوم وجود دارد (0.003 f= ، 0.05p< ) ...
BACKGROUND Schistosoma mansoni is the major causative agent of schistosomiasis. The parasite takes advantage of host signals to complete its development in the human body. Tumor necrosis factor-alpha (TNF-alpha) is a human cytokine involved in skin inflammatory responses, and although its effect on the adult parasite's metabolism and egg-laying process has been previously described, a comprehen...
