RESULTS: The comparison between core and pan-genomic comparison showed variation in the distribution of C. diphtheriae. The local isolates portrayed a heterogenous trait and a close relationship between Malaysia's and Belarus's, Africa's and India's strains were observed. A toxigenic C. diphtheriae clone was noted to be circulating in the Malaysian population for nearly 30 years and from our study, the non-toxigenic and toxigenic C. diphtheriae strains can be differentiated significantly into two large clusters, A and B respectively. Analysis against vaccine strain, PW8 portrayed that the amino acid composition of toxin and DtxR in Malaysia's local strains are well-conserved and there was no functional defect noted. Hence, the change in efficacy of the currently used toxoid vaccine is unlikely to occur.
Methods: Based on discouragement and organizational control theory, this research examined the effects of organizational external factors and rules and regulations on construction risk management among 238 employees operating in construction companies in Abuja and Lagos, Nigeria. A personally administered questionnaire was used to acquire the data. The data were analyzed using partial least squares structural equation modeling.
Results: A significant positive relationship between organizational external factors and construction risk management was asserted. This study also found a significant positive relationship between rules and regulations and construction risk management. As anticipated, rules and regulations were found to moderate the relationship between organizational external factors and construction risk management, with a significant positive result. Similarly, a significant interaction effect was also found between rules and regulations and organizational external factors. Implications of the research from a Nigerian point of view have also been discussed.
Conclusion: Political, economy, and technology factors helped the construction companies to reduce the chance of risk occurrence during the construction activities. Rules and regulations also helped to lessen the rate of accidents involving construction workers as well as the duration of the projects. Similarly, the influence of the organizational external factors with rules and regulations on construction risk management has proven that most of the construction companies that implement the aforementioned factors have the chance to deliver their projects within the stipulated time, cost, and qualities, which can be used as a yardstick to measure a good project.
BACKGROUND: The quality of life of people with disorders of sex development depends largely on the availability of good psychosocial and psychosexual management. There is a lack of qualitative systematic reviews of the literature on the experiences of people with disorders of sex development.
DESIGN: The seven steps of qualitative meta-ethnography were employed in this review.
DATA SOURCES: The following electronic databases were systematically searched until January 2017: Science Direct, Scopus, Sage online, CINAHL, PsycINFO, Medline, Wiley Online Library, and Google Scholar. Search terms for this review were "disorders of sex development," "intersex," "ambiguous genitalia," "experiences," "qualitative study," and "method".
REVIEW METHOD: A 13-item scale was applied to evaluate the quality of the selected studies and synthesized using the principles of meta-ethnography.
FINDINGS: Twelve studies met the eligibility criteria. Six major themes described the experiences of people with disorders of sex development. These included a range of physical, psychological, social, and sexual experiences which affect their quality of life. Different coping strategies were employed by individuals who live with the lifelong condition.
CONCLUSION: Disorders of sex development affect the quality of life of people living with these disorders. Nurses are tasked with providing holistic care for people with disorders of sex development in order to improve their quality of lives. As such, there is a need to explore the experiences of nurses in the management of disorders of sex development.
METHOD: Hydrazinyl thiazole substituted coumarins 4-20 were synthesized via two step reaction. First step was the acid catalyzed reaction of 3-formyl/acetyl coumarin derivatives with thiosemicarbazide to form thiosemicarbazone intermediates 1-3, followed by the reaction with different phenacyl bromides to afford products 4-20. All the synthetic analogs 4-20 were characterized by different spectroscopic techniques such as EI-MS, HREI-MS, 1H-NMR and 13C-NMR. Stereochemical assignment of the iminic double bond was carried out by the NOESY experiments. Elemental analysis was found in agreement with the calculated values.
RESULTS: Compounds 4-20 were screened for α-amylase inhibitory activity and showed good activity in the range of IC50 = 1.829 ± 0.102-3.37 ± 0.17 µM as compared to standard acarbose (IC50 = 1.819 ± 0.19 µM). Compounds were also investigated for their DPPH and ABTS radical scavenging activities and displayed good radical scavenging potential. In addition to that molecular modelling study was conducted on all compounds to investigate the interaction details of compounds 4- 20 (ligands) with active site (receptor) of enzyme.
CONCLUSION: The newly identified hybrid class may serve as potential lead candidates for the management of diabetes mellitus.
