there are several known and unknown factors for unexplained recurrent spontaneous abortion (ursa). among them, complement regulatory protein cd46 plays a pivotal role in preventing uncontrolled activation of complement and successful continuation of pregnancy. we aimed in this study to investigate the possible association of cd46 ivs1-1724 c>g polymorphism with rsa in iranian women. 141 women w...

BACKGROUND Sequence variations at the apolipoprotein (apo)C-III gene locus have been associated with increased plasma triglycerides. In particular, the S2 allele of an SstI polymorphism in the 3' untranslated region has been associated with hypertriglyceridemia in many populations. The aim of this study was to determine whether the variant S2 allele is related to increased mRNA expression in vi...

The Dobzhansky-Muller model posits that intrinsic postzygotic reproductive isolation--the sterility or lethality of species hybrids--results from the evolution of incompatible epistatic interactions between species: favorable or neutral alleles that become fixed in the genetic background of one species can cause sterility or lethality in the genetic background of another species. The kind of hy...

A necessary and sufficient condition is given for quasi-homogeneous polynomial Hamiltonian systems having a center. Then it shown that there exists bound on the number of limit cycles bifurcating from period annulus at any order Melnikov functions; explicit expression this in terms (n,k,s1,s2), where n degree perturbation polynomials, k first nonzero higher function, (s1,s2) weight exponent wit...

Background & Aim: Low back pain is the most debilitating condition, and can lead to decreased physical function, compromised quality of life, and psychological distress. Several studies have been conducted to recognize the risk factors of low back pain, but despite of strong relationship between obesity and low back pain, the underlying mechanisms are unclear. The aim of this study wa...

background: the goal of the present study was to report the results of two parallel works in which the incidence of fetal deaths and also congenital malformations among the progenies of the iranian chemical victims were studied. methods: the subjects were progenies of a randomly selected population from survivors of chemical attacks during iran-iraq conflict. totally 807 male cases ranged 18-85...

experiments revealed the existence of eight and three single nucleotide polymorphisms (SNPs) at the promoter and 30-UTR of the goat LALBA gene respectively (Table S2 and Fig. S1). We also found eight additional putative polymorphic sites at exonic (all synonymous) and intronic regions. The potential functional significance of substitutions detected at the LALBA promoter was evaluated with the T...

Previously, we introduced a monkey model for human frontal midline theta oscillations as a possible neural correlate of attention. It was based on homologous theta oscillations found in the monkey's prefrontal and anterior cingulate cortices (areas 9 and 32) in a self-initiated hand-movement task. However, it has not been confirmed whether theta activity in the monkey model consistently appears...

Third-degree perineal lacerations in 7 mares were repaired surgically by a one-stage method (Goetz technique). Primary healing occurred in all of them without any complication. The conception rate obtained after surgery was 70.1%. Five horses out of seven got pregnant after surgery and no further injury was seen at subsequent foaling. Three mares have produced several healthy foals without any ...
