Locus of control refers to the extent to which individuals believe they can control events affecting them. Social anxiety disorder, also known as social phobia, is the most common anxiety disorder. It is characterized by intense fear in one or more social situations. The aim of this study was to investigate the relationship between locus of control with anxiety and social phobia in adolescent’s...
The use as genetic markers, during transformation of Streptococcus pneumoniae, of 19 sequences differing from wild type, located throughout the amiA locus, enabled us to examine the fate of 24 single- and 11 multiple-mismatches during recombination. Tentative mismatch ranking as a function of decreasing repair efficiency by the Hex mismatch repair system is G/T = A/C = G/G (maximum repair: 90-9...
Exonuclease 1 (Exo1) is a 5'-3' exonuclease that interacts with MutS and MutL homologs and has been implicated in the excision step of DNA mismatch repair. To investigate the role of Exo1 in mammalian mismatch repair and assess its importance for tumorigenesis and meiosis, we generated an Exo1 mutant mouse line. Analysis of Exo1(-/-) cells for mismatch repair activity in vitro showed that Exo1 ...
We implement an isolation with migration model for three species, with migration occurring between two closely related species while an out-group species is used to provide further information concerning gene trees and model parameters. The model is implemented in the likelihood framework for analyzing multilocus genomic sequence alignments, with one sequence sampled from each of the three spec...
DNA variation in a 4.7-kb region of the cytosolic phosphoglucose isomerase (PgiC) locus was investigated for 21 ecotypes of Arabidopsis thaliana. The estimated nucleotide diversity was 0.0038, which was one-third of those in previously investigated loci. Since most of the nucleotide variations (93%) were singleton and doubleton, Tajima's test statistic was significantly negative. About 50% of n...
386 Students (181 female and 205 male) were selected randomly and asked to complete a demographic data sheet. Rutter's Internal and External locus of Control and the Beck Depression Inventory. Data were analyzed by t-test and analysis of variance (ANOVA). The results revealed, that 28% of students exhibited external locus of control, whereas, 72% exhibited internal locus of control. The mean sc...
