OBJECTIVES Marfan syndrome (MFS) is a severe connective tissue disorder withan autosomal dominant inheritance pattern. Early diagnosis is critical in MFS. Because of the large size of fibrillin-1 gene (FBN1), the uniqueness of mutations, and the absence of genotype-to-phenotype correlations linkage analysis can be very helpful for early diagnosis of MFS. In this study, eight polymorphic markers...

this study determines the value of linkage analysis using six rflp markers for carrier detection and prenatal diagnosis in familial dmd/bmd cases and their family members for the first time in the iranian population. we studied the dystrophin gene in 33 unrelated patients with clinical diagnosis of dmd or bmd. subsequently, we determined the rate of heterozygosity for six intragenic rflp marker...

Angiosperm systematics has progressed to the point where it is now expected that multiple, independent markers be used in phylogenetic studies. Universal primers for amplifying informative regions of the chloroplast genome are readily available, but in the faster-evolving nuclear genome it is challenging to discover priming sites that are conserved across distantly related taxa. With goals incl...

AIM The evaluation of allelic losses at the FHIT and the BRCA1 genes and at three other loci at the 17q region in a series of 34 sporadic breast cancer cases from Southern Brazil. METHODS The samples were evaluated for loss of heterozygosity (LOH) at the FHIT and the BRCA1 genes and at three other microsatellite markers at 17q, and the findings were correlated with clinicopathological paramet...

People perceive, think, and behave differently at various spatial and temporal scales. Spatiotemporal modelling of tourist movements considers how people move about or why they exhibit certain movement behaviours. Research into spatio-temporal movements of tourists can be studied from a number of different aspects. Psychologists, for example, are concerned with understanding the cognitive aspec...
