ODP Site 762 (eastern Indian Ocean) includes a section of sediment that spans the Cenomanian-Turonian Boundary (CTB) and was deposited along a continental margin during a period of widespread oceanic 09. deficiency. The rare earth element (REE) content of preand post-boundary sediment is similar to that of present-day continental slope material deposited in well-oxygenated seawater, whereas the...
Cytotactin is an extracellular matrix protein that is found in a restricted distribution and is related to developmental patterning at a number of neural and non-neural sites. It has been shown to bind specifically to other extracellular matrix components including a chondroitin sulfate proteoglycan (cytotactin-binding [CTB] proteoglycan) and fibronectin. Cell binding experiments have revealed ...
CTB-MPR is a fusion protein between the B subunit of cholera toxin (CTB) and the membrane-proximal region of gp41 (MPR), the transmembrane envelope protein of Human immunodeficiency virus 1 (HIV-1), and has previously been shown to induce the production of anti-HIV-1 antibodies with antiviral functions. To further improve the design of this candidate vaccine, X-ray crystallography experiments w...
In this study, two types of cemented tailings backfill (CTB) were prepared by breaking up the waste clay bricks (WCB) from dismantled buildings and replacing part cement with brick powder aggregate. The mechanical properties modified CTB investigated. results showed that strength 10% content increased 16.24% at curing age 28 days, while 20% only decreased 0.11%. aggregate less than can be each ...
زمینه و هدف: ترکیب یا اتصال ژنتیکی آنتی ژن ها با زیر واحد B کلرا توکسین =cholera toxin B) (ctB پاسخ آنتی‌بادی موکوسی قوی ای را ایجاد می‌کند. هدف از این مطالعه اتصال ctB به ژن کد کننده ناحیه 4 آنتی ژن حفاظت کننده (Protective antigen Domain 4=PaD4) به منظور بیان پروتئین کایمریک به عنوان کاندیدا واکسن علیه بیماری سیاه زخم می باشد. روش بررسی: در این تحقیق تجربی آزمایشگاهی واکنش PCR با پرایمرهای ا...
INTRODUCTION Tuberculosis (TB) is a serious public health problem; however, the cutaneous form remains rare. METHODS A retrospective analysis examined notified cutaneous tuberculosis (CTB) cases from 2000 to 2013 at the University Hospital Clementino Fraga Filho. RESULTS Twenty-six CTB cases were documented during this period. Erythema induratum of Bazin was the most common form, and 86.7% ...
Mucosal vaccination of capsular polysaccharide (PS) of Streptococcus pneumoniae and subsequent creation of the first line of immunological defense in mucosa were examined. Mucosal as well as systemic antibody responses to PS were evoked by peroral or intranasal immunization of BALB/c mice with PS-cholera toxin B subunit (CTB) conjugates entrapped in the alginate microspheres (AM). The bacterial...
A cholera vaccine containing killed vibrios and cholera toxin B subunit (CTB) was used to compare mucosal immunization routes for induction of systemic and mucosal Ab. Four groups of women were given three monthly immunizations by the rectal immunization (R(imm)) route, nasal immunization (N(imm)) route, or vaginal immunization route during either the follicular (V-FP(imm)) or luteal (V-LP(imm)...
Cemented tailing backfill (CTB) in underground mine inevitably experiences seepage field, which complicates its mechanical behavior. In this study, the properties and microstructure characteristics of CTB under different water pressures (SWPs) were investigated. The results show that, with increase SWP, decrease, but decreasing trend reduces gradually. Higher SWP leads looser more porous, large...
Oral administration of Ag coupled to cholera toxin B subunit (CTB) efficiently induces peripheral immunological tolerance. We investigated the extent to which this oral tolerance is mediated by CD25+CD4+ regulatory T cells (T(reg)). We found that total T(reg), KJ1-26+ T(reg) and CTLA-4+ T(reg) were all increased in Peyer's patches, mesenteric lymph nodes, and, to a lesser extent, in spleen of m...
