Mosquito-borne dengue viral fever is one of the fastest spreading global health hazards of recent times. Although it has been widespread especially in the tropics, dengue came into prominence since the early 1950’s following the epidemic in south East Asia. The commonest presentation of Dengue Fever is characterized by high fever, severe headache

Background: Ancient traditional physicians from many countries used leeching to treat a wide range of diseases for thousands of years. A large number of peptides and proteins have been identified and characterized in leech saliva extract (LSE), including anti­ thrombotic agents, cancer metastasis inhibitors and anti­microbials Currently, leech th

The purpose of this paper is to highlight the conflict of two languages, one being the mother tongue of a country and the other a second language of a country i.e. Bahasa Melayu and English language, in the process of empowering the society with knowledge in order to stay competitive in this challenging and ever-changing world. In so doing, the pap

Polygalacturonase is one of the important enzymes used in various industries such as food, detergent, pharmaceutical, textile, pulp and paper. A novel liquid/liquid extraction process composed of surfactant and acetonitrile was employed for the first time to purify polygalacturonase from Durio zibethinus. The influences of different parameters such

A phytochemical investigation of the crude extracts of the bark and leaves of Calophyllum symingtonianum has resulted in the isolation of inophyllum D, inophyllum H, calanone, isocordato-oblongic acid, amentoflavone, carpachromene and lupenone. Their chemical structures were elucidated and confirmed by spectroscopic analysis. All flavonoids and cou

Due to the significant nature of private housing project to public at large, housing developments in Malaysia is governed by stringent laws and regulations with the main purpose of protecting the interests of buyers. Despite the existence of these legal instruments, complaints on housing-related problems remain one of major consumers' complaint

Objective: To screen the antioxidant, cholinesterase and tyrosinase enzymatic inhibition activities of the leaves and heartwood of Calophyllum symingtonianum (C. symingtonianum), and the bark of Calophyllum depressinervosum (C. depressinervosum). Methods: Samples of leaves and heartwood of C. symingtonianum and bark of C. depressinervosum were test

Soda lime glass is widely used in optics, chemical apparatus, camera lens, micro gas turbines, light bulbs etc. on account of its high hardness, corrosion resistance, and excellent optical properties. These require high dimensional accuracy and flawless surface finish. However, soda lime glass is inherently brittle leading to subsurface crack propa

A simple and economical route based on a ZnCl2 mediated process was developed to synthesize hierarchical flower-like ZnO micro/nanoflakes on the surface of copper foil by 2 stages electrodeposition method (2M ZnCl2 – 0.5M ZnCl2). The prepared flakes were characterized by XRD and SEM. The morphology of ZnO can be tuned from simple isolated nanofla

Calophyllum is a pan-tropical genus belongs to the Guttiferae family and locally known in Malaysia as “bintangor”. There has been a continual interest to further investigate the phytochemistry of Calophyllum spp since this genus is a rich source of active secondary metabolites. In this study, antioxidant, cholinesterase and tyrosinase enzymatic
