A review of current trends of antibacterial Schiff base complexes: Lower and higher transition metal complexes

@#The development of metal complexes has inspired researchers to progress in this domain due to their extensive applications in the biological field. Regarding the application, binuclear metal complexes are less explored than their mononuclear counterparts. Recent development in transition metal Schiff base complexes was outlined and presented in detail with their respective vast applications, especially antibacterial. The relationship of their structure, functions, properties, and key elements that affected antibacterial activities was demonstrated. This review was aimed to present the latest advancement of numerous lower and higher transition metal complexes, especially mononuclear ones. Moreover, their various properties are highlighted for future work related to binuclear Schiff base metal complexes and to persuade future research in this exciting field.

A Comparison of Demographic Parameters of Aedes albopictus (Skuse) (Diptera: Culicidae) in Dengue Risk Area at Shah Alam, Selangor

@#Introduction: Aedes albopictus is known for its aggressiveness towards human and recently expanded to more countries outside the native regions. Thus, the demographic parameters of Aedes albopictus are important to determine the characteristics of this species mosquitoes in terms of the reproduction rates and dispersal distance. Materials and Methods: This study, was performed using a Shah Alam strain of Aedes albopictus originally collected in twenty district areas of the central zone of Shah Alam. This research applies field work-study with a cross-sectional design to investigate the demographic parameters of Aedes albopictus. The demographic evaluation of Aedes albopictus was conducted under the control environment in insectarium. Results: Investigation on the demographic parameters of Aedes albopictus clearly showed that there is a significance different observed in the total number of mosquito eggs produced in both high and low incidence rate IR areas (p=0.03). In contrast, other parameters showed insignificant value between high and low IR areas. Conclusion: The key to control the mosquito vectors population is by tracking the vector’s life cycle including its survival. Therefore, the outcome of this study may provide as a baseline to estimate the dengue outbreak in the current episystem.
