This study aims to examine the system of psychological factors that determine the desire of young people to stay in their region.

Genotype-phenotype analysis of hearing function in patients with DFNB1A caused by the c.-23+1G>A splice site variant of the GJB2 gene (Cx26).

The audiological features of hearing loss (HL) in patients with autosomal recessive deafness type 1A (DFNB1A) caused by splice site variants of the GJB2 gene are less studied than those of patients with other variants of this gene. In this study, we present the audiological features of DFNB1A in a large cohort of 134 patients with the homozygous splice site variant c.-23+1G>A and 34 patients with other biallelic GJB2 genotypes (n = 168 patients with DFNB1A).

Screening and quantification of pesticides in wetland water, ice, sediment and soil: Occurrence, transport and risk assessment.
