BACKGROUND Background: Cancer immunotherapy is a promising strategy for cancer treatment. In this strategy, the immune system is triggered to destroy cancer cells. IL-2 is an important factor in passive cancer immunotherapy that helps modulating some important immune functions. One of the IL-2 limitations is low serum half-life; therefore, repetitive high doses of the injections are required to...
BACKGROUND Serum elevations of interleukin-6 (IL-6) correlate with multiple organ dysfunction syndrome and mortality in critically injured trauma patients. Data from rodent models of controlled hemorrhage suggest that recombinant IL-6 (rIL-6) infusion protects tissue at risk for ischemia-reperfusion injury. Exogenous rIL-6 administered during shock appears to abrogate inflammation, providing a ...
Com as fontes de recursos cada vez mais escassas e a produção exponencial equipamentos eletro-eletrônicos (EEE), torna-se importante transição uma economia linear (EL) para circular (EC). O objetivo deste artigo foi analisar práticas que estão sendo adotadas pelas empresas produzem EEE com base na framework ReSOLVE sob perspectiva da EC. Esta pesquisa se classifica como aplicada, descritiva abo...
To identify strategies that enhance tumor-specific immunity in patients with ovarian carcinoma, 22 patients received four to six doses of i.p. recombinant IFN-g (rIFN-g), 200 mg/m on days 1, 3, 5, 8, 10, and 12, and i.p. recombinant interleukin 2 (rIL-2), either 6.0 3 10 IU/m (group A) or 1.0 3 10 IU/m (group B), on days 9, 10, and 11. Two patients in group A also received T-cell lines expanded...
ویروس زردی غربی چغندرقند (bwyv) beet western yellows virus یکی از ویروس های مهم بیماری زا در گیاهان می باشد. تشخیص سریع و به موقع این ویروس نقش به سزایی در اتخاذ روش های کنترل و خسارت آن دارد. از روش های متداول، معتبر و ارزان برای تشخیص ویروس در سطح وسیع، روش سرولوژیکی می باشد که در این روش تامین منبع آنتی ژن ویروسی برای استفاده در فرآیند تولید آنتی بادی پلی کلونال ضروری است. در تحقیق حاضر ژن ر...
We have examined the ability of in vivo treatment of mice with recombinant interleukin 2 (rIL-2) to affect natural immunity measured against tumor (YAC-1) or virally infected (herpes simplex type 1) target cells. rIL-2 treatment leads to significant increases in natural killer/lymphocyte-activated killer (NK/LAK) function and spleen cells recovered. This effect is dose dependent and strain rela...
We evaluated the effects of murine recombinant interleukin-4 (rIL-4) on murine peritoneal macrophages. We showed a marked, dose-dependent stimulation of respiratory oxidative burst by IL-4 in peptone-elicited murine peritoneal macrophages. This effect was abolished by a neutralizing monoclonal antibody (mAb) to rIL-4 confirming that the enhanced chemiluminescence was due to IL-4. In contrast, r...
به علت افزایش میزان مقاومت های آنتی بیوتیکی، acinetobacter baumannii یکی از مشکلات سلامت عمومی و تهدید بزرگی برای بیماران بستری در بیمارستان، رفت و آمد کنندگان به بخش مراقبت های ویژه نیروهای نظامی محسوب میشود. ممکن است واکسیناسیون این گروهای خطر وقوع و گسترش عفونت های مرتبط با آن را کاهش دهد. در مطالعه ی حا ضر امکان تحریک سیستم ایمنی خونی و سلولی توسط یکی از فاکتور های بیماریزای این باکتری بنام...
Different immunotherapy regimens using s.c. recombinant interleukin-2 (rIL-2) were studied in 76 patients with progressive metastatic renal carcinoma, malignant melanoma, colorectal cancer, B-cell lymphoma, or Hodgkin's disease. To assess the immunomodulatory capacity of rIL-2, we measured serum levels of soluble interleukin-2 (sIL-2) receptors, gamma-interferon, tumor necrosis factor-alpha, an...
PURPOSE The incidence of non-Hodgkin's lymphoma (NHL), the fifth most common malignancy in the United States, has increased over 70% in the last 30 years. Fifty percent to 75% of patients with low-grade or follicular NHL respond to rituximab therapy. However, responses are generally of limited duration, and complete responses are rare. Preclinical work suggests that human recombinant interleuki...
