STR data for 09 autosomal STR markers from Rio Grande do Sul (southern Brazil)

Allele frequencies for 09 STR autosomal loci (D3S1358, D5S818, D7S820, D8S1179, D13S317, D18S51, D21S11, FGA and VWA) included in the AmpFlSTR Profiler Plus were obtained from a sample of unrelated individuals from Rio Grande do Sul (southern Brazil).     

Chimpanzee homologous of human Y specific STRs. A comparative study and a proposal for nomenclature

Eleven Y specific microsatellites, previously studied in humans, were typed for fragment length and sequenced in chimpanzees (Pan troglodytes).The primers described by Ayub et al. (Nucleic Acids Res. 28, 2000, 2) for amplifying DYS434, DYS435, DYS436, DYS437, DYS438, DYS439 and those described by White et al. (Genomics, 57, 1999, 433) for GATA A10, A7.1, A7.2, C4, and H4, were used to amplify DNA samples from chimpanzees.Primers described for Y GATA A4 were found to amplify the same region as reported for DYS439. Moreover, the GATA A4 forward primer only matches the repeat flanking region in 14 of the 28bp, being responsible for a very weak amplification. Therefore, this system was not included in this study.The analysis of the repeat and sequence structure observed in chimpanzee and human Y chromosomes allowed evolutionary comparisons as well as the basis for improving Y STR nomenclature and therefore, a unified nomenclature for these novel STRs is proposed to the scientific community following ISFG recommendations.     

Developing an intervention to overcome procrastination

ABSTRACT

The main goal of this study was the development of a reliable intervention to overcome general procrastination orientated to college students, designed to be used in practical clinical work. The workshops involved six meetings based on behavioral and cognitive techniques, paradox intervention, and psychoeducation. 175 students participated voluntarily. Their procrastination levels were measured in a pretest, post-test, and a 3-month follow-up. After the first interview, the participants were randomly divided into three groups (Intervention A, Intervention B, and a control group with no intervention). There was a significant improvement after the intervention. After 3 months, the average score was still significantly lower than in the pretest, whereas the score of the control group remained unchanged. The participants in Workshop A scored significantly lower in the post-test than the ones in Workshop B. After 3 months, the participants in Workshop B scored significantly lower in the follow up. So both interventions resulted to be effective in reducing procrastination sustainably.
