Antigen-specific T helper cells present in peripheral blood at very low frequencies are capable of rapid clonal expansion during antigenic challenge. The exquisite specificity of this response provides for activation and expansion of a very select cohort of T cells, a feature we have used to directly identify and quantify human epitope-specific T helper cells from peripheral blood. Soluble tetr...
The extracellular matrix in asthmatic lungs contains abundant low-molecular-weight hyaluronan, and this is known to promote antigen presentation and allergic responses. Conversely, high-molecular-weight hyaluronan (HMW-HA), typical of uninflamed tissues, is known to suppress inflammation. We investigated whether HMW-HA can be adapted to promote tolerance to airway allergens. HMW-HA was thiolate...
به منظور بررسی تاثیر رژیم آبیاری و عناصر پتاسیم و روی بر عملکرد و کارایی مصرف آب گندم (wue) رقم چمران مطالعه ای به صورت کرت های یک بار خرد شده در قالب بلوک های کامل تصادفی در سه تکرار به مدت دو سال در مرکز تحقیقات کشاورزی صفی آباد دزفول اجرا شد. سه سطح اصلی آبیاری پس از50 (i50)، 75 (i75) و 100 (i100) میلی متر تبخیر از تشتک تبخیر و سه سطح فرعی کود، بدون مصرف کود پتاسیم و روی (f0)، مصرف کود پتاسی...
Environmental impacts of 15 European pig farming systems were evaluated in the European Union Q-PorkChains project using life cycle assessment. One conventional and two non-conventional systems were evaluated from each of the five countries: Denmark, The Netherlands, Spain, France and Germany. The data needed for calculations were obtained from surveys of 5 to 10 farms from each system. The sys...
eight forage sorghum cultivars (sweet jumbo, nectar, chopper, pacific bmr, speed feed, kfs1, kfs2 and kfs3) were assessed to determine the most suitable traits carrying cultivar, through a randomized complete block design with four replications during 2003-2005. ammonium phosphate (basd on p2o5) was applied at 115 kg/ha and 183 kg/ha of nitrogen (urea-based) at four application times. six trait...
the objective of this study was to evaluate the effect of different levels of irrigation and nitrogen fertilizer on nitrate movement, yield, and water use efficiency (wp) of corn in no-till planting method. the research was conducted in two years as a randomized complete block design arranged in a split block treatment design with three replicates in the safiabad agricultural research center. i...
RESUMEN The present study was carried out in a Typic Hapludand soil in the municipality of ‘El Rosal’ (Colombia) and aimed to compare the yield performance of the cultivar Criolla Colombia under foliar applications of Zn chelate (0, 1, 2 and 3 kg ha) and edaphic applications of granulated Zn sulfated (0, 1, 2 and 3 kg ha). A split-plot, randomized complete block design, with four repetitions pe...
The yield responses of sugarcane to lime and gypsum at two sites in the KwaZulu-Natal Midlands of South Africa are presented and discussed. At Dalton, on a Magwa form soil with an initial aluminium saturation index (ASI) of >80%, over a plant and four ratoon crops variety N12 gave no significant response to dolomitic lime. By contrast, variety N16 gave consistent yield responses to lime at rate...
In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...
Influenza pandemics can spread quickly and cost millions of lives; the 2009 H1N1 pandemic highlighted the shortfall in the current vaccine strategy and the need for an improved global response in terms of shortening the time required to manufacture the vaccine and increasing production capacity. Here we describe the pre-clinical assessment of a novel 2009 H1N1 pandemic influenza vaccine based o...
