Help seeking is predictor of prognosis in the first episode of psychotic disorders. Caregivers play a key role in deciding from whom to seek help. In Indonesia, caregivers often seek help from alternative healers first and health professionals later, which is believed to result in delayed psychiatric treatment and risk for poor prognosis. This study measured the duration of untreated psychosis (DUP) in a sample of 100 persons being treated for a first episode of psychosis in Yogyakarta, Indonesia. We attempted to measure and determine associations among caregivers’ explanatory models, help seeking behaviors and DUP in this sample. The data were then statistically analyzed. The DUP for this population was very short. Most caregivers were parents or spouses (72 and 12%, respectively) and at the time of being interviewed described medical explanatory models for the psychotic symptoms (60%). A majority described having visited traditional/alternative healers prior to their visit to health professionals (67%). Despite this, the DUP was not significantly different for these two groups. Thus, first resort to traditional/alternative healers did not predict prolonged DUP. Further study with a larger sample is needed to better understand the relationship between care seeking, use of alternative healers and DUP in Indonesia.
Termination translation in Saccharomyces cerevisiae is controlled by two interacting polypeptide chain release factors, eRF1 and eRF3. Two regions in human eRF1, position at 281-305 and position at 411-415, were proposed to be involved on the interaction to eRF3. In this study we have constructed and characterized yeast eRF1 mutant at position 410 (correspond to 415 human eRF1) from tyrosine to serine residue resulting eRF1(Y410S). The mutations did not affect the viability and temperature sensitivity of the cell. The stop codons suppression of the mutant was analyzed in vivo using PGK-stop codon-LACZ gene fusion and showed that the suppression of the mutant was significantly increased in all of codon terminations. The suppression on UAG codon was the highest increased among the stop codons by comparing the suppression of the wild type respectively. In vitro interaction between eRF1 (mutant and wild type) to eRF3 were carried out using eRF1-(His)6 and eRF1(Y410S)-(His)6 expressed in Escherichia coli and indigenous Saccharomyces cerevisiae eRF3. The results showed that the binding affinity of eRF1(Y410S) to eRF3 was decreased up to 20% of the wild type binding affinity. Computer modeling analysis using Swiss-Prot and Amber version 9.0 programs revealed that the overall structure of eRF1(Y410S) has no significant different with the wild type. However, substitution of tyrosine to serine triggered the structural change on the other motif of C-terminal domain of eRF1. The data suggested that increasing stop codon suppression and decreasing of the binding affinity of eRF1(Y410S) were probably due to the slight modification on the structure of the C-terminal domain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
