in drought stress condition, it is important to estimate the n and k requirement of sugar beet. a drought-tolerant sugar beet genotype, bp karaj, was evaluated in split plot factorial design based on a randomized complete block design with four replications at motahari research station, karaj, iran for three years. main plots were allocated to irrigation treatments including normal irrigation (...

Parenteral vaccination of BALB/c mice primed by infection with H3N2 variants of influenza A virus results in a reduced production of N2 antibody in response to homologous (H3N2) vaccine compared with the response to an H7N2 vaccine equal in N2 immunologenicity. We now have studied the interaction in vitro of purified splenic B and T lymphocytes from variably immunized mice to ascertain the cell...

For a classical theory T , H(T ) denotes the intuitionistic theory of T -normal (i.e. locally T ) Kripke structures. S. Buss has asked for a characterization of the theories in the range of H and raised the particular question of whether HA is an H-theory. We show that T i ∈ range(H) iff T i = H(T ). As a corollary, no fragment of HA extending iΠ1 belongs to the range of H. A. Visser has alread...

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...

in order to effects of sulfur and manure on grain yield, yield components, and some physiological traits of corn hybrid ksc 704 in calcareous soils of kermanshah province, a factorial experiment was carried out based on a randomized complete block design with three replications. sulfur fertilizer in four levels 0, 250, 500 and 750 kg ha-1 and manure in four levels 0, 4, 8 and 12 t ha-1 were app...

background and aims: the contribution genetic and antigenic diversity of h9n2 influenza viruses in evading from immune responses, cytotoxic t lymphocytes (ctl) epitopes in hemagglutinin (ha) protein restricted by hla binding peptides was identified. materials and methods: phylogenetic analyses were carried out for all of full length ha and deduced amino acid sequences of h9n2 viruses available ...

Monoclonal antibody HT462 recognizes a human T-cell leukemia virus type I (HTLV-I)-associated Mr 52,000 glycoprotein (HA-gp52), which is found on the surface of HTLV-infected cells. Whether HA-gp52 is encoded by the virus or by the infected cells has not yet been established. Using monoclonal HT462 in a competitive binding assay, natural human antibodies specific for HA-gp52 were detected in 97...

CONTEXT Polycystic ovary syndrome (PCOS) is a triad of anovulation, insulin resistance, and hyperandrogenism. Androgen excess may correlate with metabolic risk and PCOS consensus criteria define androgen excess on the basis of serum T. Here we studied the utility of the androgen precursor serum androstenedione (A) in conjunction with serum T for predicting metabolic dysfunction in PCOS. PATIE...

An Ultic Haploxeralf soil collected from ridges built into the slopes of the Coastal Mountain Range of Central Chile was used in applications of humic and fulvic acids (HFA) extracted from sludge from sewage treatment plants, in combination with gypsum (CaSO4). A total of 12 treatments were applied by combining four doses of HFA (0, 20, 30 and 40 t ha-1) with three doses of gypsum (0, 1.2 and 6...

The polymorphic minor histocompatibility Ag HA-1 locus encodes two peptides, HA-1(H) and HA-1(R), with a single amino acid difference. Whereas the immunogenicity of the HA-1(R) allele has not yet been shown, the nonameric HA-1(H) peptide induces HLA-A2-restricted cytotoxic T cells in vivo and in vitro. It is not known whether the mHag HA-1(H) or HA-1(R) associates with other HLA class I molecul...
