Paddy cultivation is one of the widely planted crop in Malaysia. The growth of agricultural activity leads to the use of Organophosphate pesticide to protect the crop. This study is to determine the relationshi p between the levels of blood cholinesterase with the performance of motor coordination of children living in paddy farming area in Tanjung Karang, Selangor. This cross sectional study was conducted among 683 children from four schools in an agricultural area. Majority of the children have at a family member worked as farmer and was involved with pesticides. A set of questionnaire on the was given to the children to be filled by t heir parents. To measure their exposure to pesticide, blood cholinesterase levels were measured. Blood samples were taken through finger prick technique and were then analysed using LOVIBOND 412870 AF287. The children were administered with motor - coordina tion performance test using WHO Neurobehavioral Core Test Battery and McCarthy Learning Ability Scale. Young group children (6 - 85 years) showed a mean score of 56.66 in motor - coordination test while older group children (10 - 11)= years) scored a mean of 45 .37. There was a significant relationship between blood cholinesterase level and motor coordination performance among the young - group children (r=0.215, p<0.001) and the older - group children (r=0.106, p=0.049). Based on the Linear Regression test results, total household income of family, and mode of transport used were found to have significant relationship with blood cholinesterase level of children in both groups. In addition, blood cholinesterase level and mothers’ occupation were found to have signific ant relationship with the motor - coordination performance of all children.

Tissue engineering aims to restore lost, damaged, diseased or defective tissues in the human body using engineered or regenerated products. The advancement of tissue engineering has given a promising opportunity for better clinical practice in treating dental patients especially in the fields of endodontic, bone and periodontal tissue as well as whole tooth regeneration. In this review, we briefly summarise the possible selection criteria of scaffolds for potential tissue engineering applications in dentistry. Biochemical and physical properties, as well as scaffolding approaches involved in the selection of an ideal scaffold for dental tissue engineering, are also discussed in this review. This review also discussed major applications of tissue engineering in the dentistry field, which can create a paradigm for future studies of tissue regeneration by using selected cells and scaffolds as an alternative treatment in dentistry.

ABSTRACT Granulomatosis with polyangiitis (GPA) is a rare multisystem disease. Although GPA is rare, it commonly presents in a localised stage where its manifestation involves the upper or lower respiratory tract before progressing to a generalised stage. Therefore, most patients with GPA will visit an oral surgeon or an otolaryngologist to seek treatment. However, the diagnosis of GPA is often delayed as GPA is not frequently considered as a differential diagnosis in common oral and facial diseases. The lack of gold standard investigation for the diagnosis of GPA makes management of this case, a diagnostic conundrum. We herein report a patient who was diagnosed with bilateral acute otitis media and left mastoiditis complicated with facial nerve palsy, and later developed tongue ulceration one month after his initial presentation. The ear, facial and oral symptoms represent a diagnostic red herring to a full-blown generalised stage of GPA.

Introduction: High-intensity interval training (HIIT) has been found to improve cardiometabolic health outcome as compared to moderate-intensity continuous exercise. However, there is still limited data on the benefits of HIIT on the expression of regulatory proteins that are linked to skeletal muscle metabolism and insulin sensitivity in obese adults. This study investigated the effects of HIIT intervention on expressions of peroxisome proliferatoractivated receptor-γ coactivator 1-α (PGC-1α) and adiponectin receptor-1 (AdipoR1), insulin sensitivity (HOMAIR index), and body composition in overweight/obese individuals. Methods: Fifty overweight/obese individuals aged 22-29 years were assigned to either no-exercise control (n=25) or HIIT (n=25) group. The HIIT group underwent a 12-week intervention, three days/week, with intensity of 65-80% of age-based maximum heart rate. Anthropometric measurements, homeostatic model of insulin resistance (HOMA-IR) and gene expression analysis were conducted at baseline and post intervention. Results: Significant time-by-group interactions (p<0.001) were found for body weight, BMI, waist circumference and body fat percentage. The HIIT group had lower body weight (2.3%, p<0.001), BMI (2.7%, p<0.001), waist circumference (2.4%, p<0.001) and body fat percentage (4.3%, p<0.001) post intervention. Compared to baseline, expressions of PGC-1α and AdipoR1 were increased by approximately three-fold (p=0.019) and two-fold (p=0.003) respectively, along with improved insulin sensitivity (33%, p=0.019) in the HIIT group. Conclusion: Findings suggest that HIIT possibly improved insulin sensitivity through modulation of PGC-1α and AdipoR1. This study also showed that improved metabolic responses can occur despite modest reduction in body weight in overweight/obese individuals undergoing HIIT intervention.

Disaster risk reduction (DRR) plays essential roles in ensuring food security to avoid adverse social, economic and financial implications to the disaster victims. This article aims to review existing DRR strategies in food security during flood disasters and recommend strategies that can be adapted into policies in Malaysia according to the Sendai Framework. Sendai Framework provides comprehensive, globally recognized priority themes in DRR while highlighting governmental and stakeholders’ responsibility. A literature review was carried out by searching available published literatures from online databases and selected information used in this review is taken from articles, journals, reports, national reports, news, and thesis regarding the topic from November 2021 to January 2022. This review revealed that DRR strategies of food security during flood disasters in Malaysia lack one out of 14 work areas in four priorities in the Sendai Framework, which is the national-level risk and vulnerability assessment system and tools. This article proposed 19 recommendations to improve eight work areas across all four priority areas to enhance national food security during flood disasters.
