Introduction Large-scale association studies have been proposed as a promising means of identifying pre-disposing genes in common complex diseases. Genome-wide linkage disequilibrium (LD) mapping of common diseases could be more powerful than linkage analysis if the appropriate density of polymorphic markers were known and if the genotyping effort and costs could be reduced. An obvious choice f...

background: dermatophytes are the most common causative agents of superficial mycoses. species identification of these fungi is important from therapeutic and epidemiological point of wive. traditional approaches for identification of dermatophytes at the species level, relying on macroscopic and microscopic features of the colonies, usually are time-consuming and unreliable in many circumstanc...

Introduction In cross-sectional epidemiological studies, a random sample is usually drawn from the general population in to make conclusions about the underlying general population. This approach assumes that the response probability is the same for all subjects in the population. However, it is known (1) that participants and non-participants differ in terms of their personal and disease-relat...
