precise application of the n fertilizer rate is critical to achieve maximum yield. in major regions, empirical methods were used for determining n fertilizer requirement. these methods cannot take into account variation in management and environmental conditions on determining fertilizer requirement. crop simulation models can provide an alternative means of determining the optimum crop n requi...
myeloperoxidase (mpo) and paraoxonase-1 (pon1) are inflammatory and anti-inflammatory enzymes, respectively that have been involved in the pathogenesis of coronary artery disease (cad). in this study we sought to evaluate the relations of mpo and pon1 with high density lipoprotein (hdl) mean size in patients with acute coronary syndrome (acs). collectively, 50 control subjects and 50 patients w...
background: discriminating latent tuberculosis infection (ltbi) from active tbi may be challenging. the objective of this study was to produce the recombinant l-alanine dehydrogenase (aladh) antigen and evaluate individuals with ltbi, those with active tbi, and uninfected individuals by enzyme-linked immunospot assay (elispot) in order to distinguish ltbi from active tbi. methods: this explorat...
intercellular adhesion molecule-1 (icam-1) lys469glu (k469e) polymorphism and gly 241arg (g241r) polymorphism might play important roles in cancer development and progression. however, the results of previous studies are inconsistent. the aim of this study was to evaluate the association between icam-1 k469e and g241r polymorphisms and the risk of cancer by meta-analysis.a comprehensive literat...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
in the present work, b-zsm-5 zeolite membranes were synthesized on porous tubular α-alumina supports by several subsequence in situ crystallization hydrothermal treatments. the tio2- bohmite and ɣ- alumina intermediate layers were applied to improve the lattice matching between zeolite layer and the support. the uniform membrane intermediate layers with low permeation resistance were prepared o...
background: immunological factors are important in pregnancy loss because of the interaction between mother and fetus. t-regulatory cells as the component of humeral immune response play important role in the fetu-maternal interface. one of the regulatory mechanisms for these cells is mediated by antigen independent co-stimulatory signals and interaction of cytotoxic t-lymphocyte antigen 4 (b7/...

background: leishmania major is an intracellular parasite transmitted through the bite of the female phlebotomine sand flies. leishmania major is able to escape the host immune defense and survive within macrophages. modulation of the nf-κb (nuclear factor-kappa b) activation and suppression of the pro-inflammatory cytokines by l. major are the main evasion mechanisms that remain to be explored...
background: the up-regulation of galectin-3, galectin-9, and galectin-15 expression in the luminal and glandular epithelium was reported in preparation of the endometrium for embryo implantation at the midlutheal phase. however, no data was available regarding the expression and the distribution pattern of galectin-8 in the human endometrium during a regular menstrual cycle. objective: the curr...
