iran is a part of the secondary centre of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. the amplified fragment length polymorphism (aflp) marker was applied to investigate the genetic variations among five major iranian melon cultigens (cucumis melo) and ‘ananasi’ as a general well-known cultivar. ten primer pairs were used on 90 indiv...

identification  of clinically  significant  nocardia  species  is essential  for the definitive diagnosis, predict antimicrobial susceptibility, epidemiological purposes,  and  for  an  effective  treatment.   conventional   identification   of nocardia species in routine medical laboratories which is based on phenotypic (cellular morphology, colonial characteristics), biochemical and enzymatic...

background coronary artery disease (cad) is the most common cause of death worldwide. mef2a directly regulates target genes in the process of muscle development. this gene product is a transcription factor. mef2a protein in homodimer or heterodimer forms binds to a/t-rich cis elements with conserved sequence in promoter, regulator, and enhancer of many genes, which are determining in evolution ...

Ammonium hydrosulphide has long since been postulated to exist at least in certain layers of the giant planets. Its radiation products may be reason for red colour seen on Jupiter. Several ammonium salts, NH3 and an acid, have previously detected comet 67P/Churyumov-Gerasimenko. The acid H2S is fifth most abundant molecule coma 67P followed by NH3. In order look salt NH4+SH-, we analysed situ m...

STAT proteins have the function of signaling from the cell membrane into the nucleus, where they regulate gene transcription. Latent mammalian STAT proteins can form dimers in the cytoplasm even before receptor-mediated activation by specific tyrosine phosphorylation. Here we describe the 3.21-A crystal structure of an unphosphorylated STAT5a homodimer lacking the N-terminal domain as well as t...

A 190-kb mitochondrial DNA sequence interrupted by seven foreign DNA segments was identified in rice chromosome 12. This fragment is the largest mitochondrial fragment translocated into the rice nuclear genome. The sequence is composed of a 190-kb segment of mitochondrial origin corresponding to 38.79% of the mitochondrial genome, 45 kb comprising four segments of retrotransposon origin, and 13...

in persian, the only syllable type with consonant clusters is cvcc, where its coda can be filled with two consonants. the present article attempts to find whether these two consonant conform the sonority sequencing principle or not. for this reason, the persian words with cvcc syllable type are gathered from persian dictionaries and are classified based on the vowel filling the nucleus of the s...

Objective(s): We previously conducted an in silico research on the interactions between the ribosome display-selected single chain variable fragment (scFv) and factor H binding protein (fHbp) of Neisseria meningitidis. We found that heavy chain variable (VH) fragment of this scFv had considerable affinity to fHbp. These results led us to evaluate the ability of this sm...

introduction: oxytocin is a active neuropeptide of central nervous system. in this study the effects of naloxone (opioid receptor antagonist) and yohimbine (α-2 adrenergic receptor antagonist) on analgesic effect of oxytocin applied into the locus coeruleus (lc) nucleus were investigated. methods: adult male wistar rats were used. animals divided into different groups receiving saline, oxytocin...
