the engineering of transgenic canola (brassica napus l. ) to make tolerance to the broad-spectrum herbicide, glyphosate, is one of the most effective approaches for weed management. glyphosate inhibits the enzyme epsps (5-enolpyruvylshikimate-3-phosphate synthase) enzyme which functions in the shikimate pathway and has a key role in biosynthesis of aromatic amino acids required for survival of ...

this study was performed to investigate two polymorphic sites from cyp19 gene (pvuii and mspi) and one polymorphic site from erα gene (snabi) in four cattle breeds including mazandarani, taleshi, sistani and simmental. in overall 278 samples for cyp19 and 206 samples for erα marker sites were genotyped using polymerase chain reactionsingle-strand conformation polymorphism (pcr-rflp) procedure. ...

suicide is a major public health concern, with approximately one million people committing suicide world-wide each year .risk factors for suicidal behavior include, psychiatric and medical illness, impulsivity, aggression, alcohol and drug abuse specially stimulants, and  stress. neurobiological, brain mappings and biochemical studies have revealed that suicide victims experiencing a large numb...

background: molecular diversity of leishmania major and its morphological changes have become a controversial issue among researchers. some aspects of polymorphic shapes of amastigotes in clinical manifestations along with molecular variation were evaluated among suspected patients of some exceptional zoonotic cutaneous leishmaniasis locations in northern khuzestan, southwestern iran. methods: ...

essential hypertension (eh) accounts for 90-95% of hypertension cases. eh, as a progressive cardiovascular syndrome arising from complex and interrelated etiologies, results from combined and interactive effects of genetic and environmental factors. the objective was to investigate the ace i/d and gnb3 c825t polymorphisms and both genotypes combined with seeking gene-gene interactions to furthe...

objective(s): foxp3 gene is an x-linked gene that encodes foxp3 protein, an essential transcription factor in cd4+cd25+foxp3+ regulatory t (treg) cells.  we aimed, in the present study, to investigate the association of two foxp3 polymorphisms, -2383 c/t (rs3761549) and ivs9+459 t/c (rs2280883), with lung cancer. materials and methods:  in a case-control study we analyzed genotypes and alleles ...

present investigation was carried out to identify dna polymorphism of il-2rγ and chb6 genes. sixty five birds belonging to the indigenous chicken of himachal pradesh were utilized. good quality dna samples were subjected to pcr-rflp analysis using chicken specific primers. overnight restriction enzyme digestion was carried out at 37°c with iu hph i and pvu ii for il-2rγ and chb6 genes, respecti...

canine distemper virus (cdv) creates a very contagious viral multi-systemic canine distemper (cd) disease that affects most species of carnivora order. the virus is genetically heterogeneous, particularly in section of the hemagglutinin (h) gene. sequence analysis of the h gene can be useful to investigate distinction of various lineages related to geographical distribution and cdv molecular ep...

We have observed a sample of 15 and 8 quasars with redshifts between 0.11 and 0.87 (mean value 0.38) in the J and K' bands respectively. Eleven of the quasars were previously known to be associated with extended emission line regions. After deconvolution of the image, substraction of the PSF when possible, and identification of companions with the help of HST archive images when available, exte...

We present ultraviolet photometry for a sample of morphologically early-type galaxies selected by matching the Sloan Digital Sky Survey Data Release 1 with Dept. of Physics and Astronomy, UCLA, Los Angeles, CA 90095-1547 Max-Planck Institut für Astrophysik, D-85748 Garching, Germany Department of Physics and Astronomy, The Johns Hopkins University, Homewood Campus, Baltimore, MD 21218 Californi...
