Several questions remain unanswered concerning the effects of long-term methylphenidate treatment in individuals with attention-deficit/hyperactivity disorder (ADHD). It has been speculated that repeated methylphenidate treatment may facilitate abuse of the drug or psychological dependence. In the present study, we conducted conditioned place preference(More)
We conducted the world’s first experiments under semi-field conditions (ACL-2 field house) to assess the mating competitiveness of genetically sterile RIDL male mosquitoes (513A strain). The field house is a state-of-the-art, fully-contained trial facility, simulating the living space for a household of 2–4 people in Peninsular Malaysia. Ten genetically(More)
Dengue is the most important mosquito-borne viral disease. No specific treatment or vaccine is currently available; traditional vector control methods can rarely achieve adequate control. Recently, the RIDL (Release of Insect carrying Dominant Lethality) approach has been developed, based on the sterile insect technique, in which genetically engineered(More)
BACKGROUND There has been no comprehensive study on biochemical characterization of insecticide resistance mechanisms in field populations of Malaysian Culex quinquefasciatus. To fill this void in the literature, a nationwide investigation was performed to quantify the enzyme activities, thereby attempting to characterize the potential resistance mechanisms(More)
BACKGROUND The health-enhancing benefits of physical activity (PA) on hypertension and diabetes have been well documented for decades. This study aimed to determine the association of PA with systolic and diastolic blood pressure as well as blood glucose in the Malaysian adult population. METHODS Data were extracted from the 2011 National Health and(More)
Wolbachia-based vector control strategies have been proposed as a means to augment the currently existing measures for controlling dengue and chikungunya vectors. Prior to utilizing Wolbachia as a novel vector control strategy, it is crucial to understand the Wolbachia-mosquito interactions. In this study, field surveys were conducted to screen for the(More)
— This paper presents a balanced antenna design for a six-port receiver architecture. The conventional six-port architectures require at least 4 distribute components and a balun is needed if a balanced antenna is used. In order to use the balanced antenna integrated six-port architecture having less number of distribute components and no additional balun,(More)
