Hydroxyapatite, (HA; Ca1O(PO4)6(OH)2) has been successfully applied in medical and dental applications for several years due to its excellent biocompatibility. The usage of HA in Malaysia, however, is limited due to the lack of availability. Therefore the aim of this work is to produce HA materials from both pure chemicals and from Malaysian natural limestone precursors, and to compare their bulk properties. However, parts of Malaysian natural limestone deposits actually consist of a combination of Ca(OH)2 and CaCO3. In order to utilise the limestone to produce HA material, the combination of these commercially pure chemicals as HA precursors should still work. In order to test this hypothesis, two HAs were produced by wet synthesis technique utilising (a) combination of Ca(OH)2 + CaCO3 from pure commercial chemicals [WCC] and (b) a local natural limestone [WL] precursors. The HAs produced; WCC and WL, were compacted into discs and sintered at 1250 degrees C. The characterisations and evaluations conducted were XRD, SEM-EDX, FTIR and shrinkage factor. The results indicate that WL gives slightly better bulk properties compared to WCC.

Poly (p-phenylene vinylene) (PPV) was synthesized from p-xylylene bis(tetrahydrothiophenium chloride) using the Wessling route and characterized by Fourier Transform Infra-Red (FTIR) and UV-visible (UV-VIS) spectroscopic techniques. The significance of thermal treatment along with evolution of precursor polymer to polymer PPV was also studied through these spectroscopic techniques. Thermally Stimulated Current (TSC) measurements indicated the presence of crystallization, sulphonium group which occurred through the evolution from precursor polymer to polymer PPV during thermal treatment.

Serological confirmation of dengue in 1,410 school-going children aged 7-18 years
provided prevalence data for 16 different sites in Malaysia. These sites ranged from highly
urbanized cities to small towns. We found that at least ~7 % of children in the study group had
been exposed to dengue by age 12 and ~16% by age 18. Here we report that the dengue
seroprevalence correlates with i) increasing land development and decreased vegetation,
and ii) the overall population growth. Water bodies did not significantly affect dengue
prevalence. High prevalence of dengue was also recorded in few of the non-urban sites
suggesting the expanding geographical locality of those who get dengue in Malaysia in
tandem with increased land usage activities. These findings highlight the need to give closer
consideration to future urban planning and development, taking into consideration the
changing demography and the importance of built environment to mitigate the increasing
incidence of dengue in the non-urban areas of Malaysia.
