VACTERL association represents a rare condition with broad spectrum of coexisting congenital abnormalities. Although multifactorial origin has been described, the etiology is still unclear. Prenatal diagnosis can be challenging, as specific characteristics may difficult to determined before birth. This case report describes finding multiple abnormalities in male fetus at 30 weeks gestation. The...

Parent-of-origin differential DNA methylation has been associated with regulation of the preferential expression of paternal or maternal alleles of imprinted genes. Based on this association, recent studies have searched for parent-of-origin dependent differentially methylated regions in order to identify new imprinted genes in their vicinity. In a previous genome-wide analysis of mouse brain D...

Although many studies have reported an association between total white blood cell count and metabolic syndrome, relatively few reports are available on the association between differential white blood cell counts and metabolic syndrome. The medical records of 15,654 subjects (age, median 46, range 14-90 yr; 8,380 men and 7,274 women) who visited the Center for Health Promotion were investigated...

type e hepatitis is caused by an unclassified virus producing acute self-limited hepatitis in different parts of the world. in order to estimate the prevalence of hepatitis e virus seropositivity in tehran blood donors, a cross– sectional study was performed by the enzyme immunoassay method from 2003 to 2004 in a group of 90 blood donors. we noticed that 7 cases (7.8%) were anti-hev ab positive...

introduction: a thyroid nodule is a palpable swelling in a thyroid gland with an otherwise normal appearance. palpable thyroid nodules occur in 4 to 7 percent of the population. nodular thyroid diseases are more frequent in women than in men. most actions of thyroid hormone are mediated by the active form of thyroid hormone. d2 is essential for formation of active hormone of t3 through deiodina...

the flowering and fructification period of the chilean strawberry (fragaria chiloensis (l.) duch.) is restricted to approximately 2 mo, which seriously limits the commercial development of the species. the objective of the current investigation was to identify inter simple sequence repeat (issr) polymorphisms associated with flowering duration in accessions of f. chiloensis. the flowering durat...

the enormous growth of the world wide web in recent years has made it necessary to perform resource discovery efficiently. for a crawler it is not an simple task to download the domain specific web pages. this unfocused approach often shows undesired results. therefore, several new ideas have been proposed, among them a key technique is focused crawling which is able to crawl particular topical...

in the current study, the information on occurrence, distribution and host aphid-plant associations for the species of praon haliday in iran are presented. eight species of praon were found in the areas under study, which include four previously reported species, viz. praon absinthi bignell, praon barbatum mackauer, praon exsoletum (nees) and praon volucre (haliday), and four new records, praon...

background: endometriosis influenced by both genetic and environmental factors. associations of glutathione s-transferases (gsts) genes polymorphisms in endometriosis have been investigated by various researchers; however, the results are not consistent.objective: we examined the associations of gstm1 and gstt1 null genotypes and gstp1 313 a/g polymorphisms with endometriosis in an iranian popu...

The association between primary biliary cirrhosis (PBC) and cutaneous vasculitides is well recognized. Pustular skin lesions though, have been described in association with hepatobiliary diseases other than PBC. Once the more common infective pustular rashes have been excluded, the differential diagnoses for a pustular skin rash are acute generalized exanthematous pustulosis (AGEP), Sweet's Syn...
