This short report aims to describe the Circle of Care (COC) Project in Malaysia. This is an example of smart partnership between the Malaysian Psychiatric Association (MPA) and Johnson and Johnson which began in 2003. By means of philanthropic funds from an industrial company, many people have benefited in many different aspects through the project. It consists of three main psychosocial activities: education and support programme for carers and families of people with mental illness; psychosocial rehabilitation for patients with mental illness; and mass education for the people in promoting mental health and prevention of mental health problems and illness. To date, the project has either fully or partially funded hundreds of activities along the line of these three objectives. While there has been growth of psychosocial interventions in the country contributed by the project, it is faced with a few challenges which are becoming the next focus of actions of MPA.
The presence of 226 Ra in water is a great concern in human life since it can cause health risk to a certain extent. In the state of Kelantan, being known of its granitic area, there is a lack measurement of 226 Ra content in river water, since water is the major source of water supply. According to the INTERIM National Water Quality Standards for Malaysia (INWQS), 226 Ra activity concentration in water cannot exceed 0.1 Bq/L. For this reasons, this research was planned to carry out a systematic measurement of water along Sungai Kelantan. Liquid Scintillation Counting was used for measurement of 226 Ra in water samples from Sungai Kelantan mainly in district of Kuala Krai. In this paper, the results obtained is about 26 water samples, filtered and unfiltered, collected along Sungai Lebir, Sungai Sok and Bukit Sabah. Thus, the assessment activity concentration of 226 Ra in river water was obtained as well as annual effective dose for consumption of drinking water.
Detection and analysis of resin is particularly significant since the commercial value of agarwood is related to the quantity of resins that are present. This article explores the potential of a scanning electron microscope in combination with new non-destructive 3D visualization technique, X-ray micro-computed tomography, as imaging tools to visualize micro-structure resin in agarwood. These techniques were used to compare two samples of agarwood chips: high grade and low grade. From the results, it can be concluded that a wood cell filled with resin deposit have a higher attenuation. It can be shown that the combination of scanning electron microscopy and micro-CT can offer high resolution images concerning the localization and structure of resin inside Agarwood. While the second allows the 3D investigation of internal structure of agarwood, the first technique can provide details 2D morphological information. These imaging techniques, although sophisticated can be used for standard development especially in grading of agarwoodlbr commercial activities.
Kenaf fibre that is known as Hibiscus cannabinus, L. family Malvaceae is an herbaceous plant that can be grown under a wide range of weather conditions. The uses of kenaf fibres as a reinforcement material in the polymeric matrix have been widely investigated. It is known that epoxy has a disadvantage of brittleness and exhibits low toughness. In this research, liquid epoxidized natural rubber (LENR) was introduced to the epoxy to increase its toughness. Kenaf fibres, with five different fibre loadings of 5%, 10%, 15%, 20% and 25% by weight, were used to reinforce the epoxy resins (with and without addition of epoxidized natural rubber) as the matrices. The flexural strength, flexural modulus and fracture toughness of the rubber toughened epoxy reinforced kenaf fibre composites were investigated. The results showed that the addition of liquid epoxidized natural rubber (LENR) had improved the flexural modulus, flexural strength and fracture toughness by 48%, 30%, and 1.15% respectively at 20% fibre loading. The fractured surfaces of these composites were investigated by using scanning electron microscopic (SEM) technique to determine the interfacial bonding between the matrix and the fibre reinforcement.
The aim of this study was to investigate the effects of a two week reduction in training load on selected physiological and performance among junior cyclist. Twenty seven male junior cyclists (age= 16.6±0.7 years, height=165.6±6.1 cm, weight= 54.1±8.1 kg) were matched into either the control group (n=13) or the experimental group (n=14) using their initial VO2max values. Both groups followed a 12-week progressive endurance training program and subsequently, the experimental group (EXP) engaged in a two week tapering (recovery via a reduction in training loads) phase. The control group continued with their normal training routine. A simulated 20 km time trials performance and a graded exercise test on cycle ergometer were performed before and after endurance training and after the two week tapering protocol. Following the conclusion of the two week intervention or no intervention program both groups undertook a TT20km. Results showed no significant difference in the TT20km performance. Compared to the CON group, the EXP group showed significant changes in all the selected physiological variables tested, p
This study aimed to analyze consumers’ perceptions and acceptance toward ‘belacan’. Results
showed internal reliability of above 0.7 for sections analyzed. Factor analysis found two underlying factors in the section designed to examine consumers’ perceptions. The overall consumers’ perception had a positive and moderate correlation with their acceptance and was significant at .01. Results also showed that ‘belacan’ consumption level was relatively frequent and well accepted by all races in Malaysia. The findings of the study would be noteworthy to the fishery industry and the small and medium industry (SME) in Malaysia in meeting consumers’ needs.
Amitraz poisoning is rare and there has been no reported cases in the Malaysian literature. Ingestion of this compound carries many life threatening side effects. We describe a case of Amitraz poisoning in an 18 years old young adult. He developed hypotension, required ventilatory support and a day of intensive care unit stay. He had a quick recovery after he was treated symptomatically and was discharged well after 3 days.
Neck abscess is still common in developing countries. Often the presentation is late especially when the pain becomes intolerable or the airway is compromised. Intramuscular abscess in the neck is very rarely encountered. We report a case of an abscess of the right sternocleidomastoid. The culture grew Proteus mirabilis. The outline of management is discussed.
It is ironical to realize that a perfect and free nutritional product, individually produced and naturally distributed to all families, is not universally used. This product is of course breast milk that nurtures the optimal health, growth and development of the human young. Breast milk also protects infants and young children from and prevents diseases in the short and long term. (Copied from article)
Texture evolution of NiO formed during oxidation of polycrystalline single oriented (100) Ni-Cr was investigated. This foil was also termed rolling assisted biaxially textured substrate (RABiTS). X-ray diffractograms of oxidized Ni-Cr RABiTS foil showed the existence of mostly (200) NiO indicating (100)-type NiO formed exclusively on (100) singly oriented Ni-Cr grains. Epitaxial relationship between the two layers is observed. However the dual-in-plane texture was recorded.
The in-plane texture was assessed by conducting phi scan and plotting series of pole figures measured at (111) NiO peak. The mechanism of the oxides formation was proposed to take into account the formation of (100)-type NiO. Cross section morphology of the oxidised foils reveals two oxidation layers; fast growing external layer consisting of the (100)-type NiO and an internal layer consisted of mostly Cr2O3 and maybe NiCr2O4. The thickness of NiO was ~ 10Pm. Cr2O3 formed as needle-like oxides embedded in a matrix of Ni foil. Inward diffusion of oxygen is believed to have caused this to happen. The external NiO layer was consisted of duplex microstructure characterised by columnar layer growing vertical on the surface of the metal and a few micron thick of equiaxed NiO. Delamination of the outer NiO layer often occurred at the columnarequiaxed interface which could be cured by CeO2 deposition on the foil prior to the oxidation process. CeO2 was deposited by conversion immersion using Ce(NO3)3.6H2O solution. (200) NiO formed on this coated sample as well.
We put attention on Intrinsic Josephson Junction (IJJ) to study the fundamental physic for device applications. Convenient self-flux method was used to grow BSCCO single crystals. We investigated the lid effect to examine the single crystal growth of high TC (Critical Temperature). We found that for the crystal growth with no lid, two stage transitions of TC ≅ 61 K and 77 K were observed. While for the crystal growth with lid, the BSCCO has TC ≅ 80K, ΔTC = 10K and approximately average size5x2mm 2 . When we increased weight of lid, the single crystal have increased to TC =80K, ΔTC = 4K and the typical size was ≅7x3mm 2 . TC and the crystal growth show a tendency to increase by the effect of the lid. From observed quasi-particle characteristics, c-axis direction changed from semiconductor to intrinsic Josephson characteristic with decreasing temperature.
Breast-feeding offers many benefits to the baby and the mother. For instance, breast milk provides the right balance of nutrients to help an infant grow into a strong and healthy toddler. Even though breastfeeding is a natural process, it is not always easy. In certain situations, some mothers are unable to breastfeed their babies or the babies are unable to adapt to breastfeeding. This will lead to the use of bottle-feeding. The effect of breast-feeding and bottle-feeding on physical growth has been well established but less has been concentrated on the craniofacial growth and dental development. This review reveals the effects of breast-feeding and bottle-feeding on craniofacial growth and dentoalveolar development based on the available literature.
This paper outlines the past five decades of scientific interests and advances in medicinal plant research in Malaysia. Initially the prime interest of research programmes has been on phytochemical studies leading to the discovery of biologically active compounds as chemical templates to produce new drug candidates. As the Malaysian herbal medicine market experiences an extraordinary growth, the research approaches taken have recently included activities to develop herbal medicines into quality, efficacious and safe products for human consumption. Advances in chromatographic and spectroscopic techniques have had a tremendous impact on the isolation and structure elucidation of the constituents of medicinal plants. The development of a series of bioassay methodologies and utilization of bioassay-guided isolation techniques have contributed significantly to the progress of medicinal plant research in Malaysia. Research work on some medicinal plants carried out by the local scientists will be illustrated as examples.
Effects of cultural practice under different habitats, of well-managed monoculture plantation and growing wild under rubber trees, were studied in Aquilaria malaccensis (Karas) leaves. This study was carried out on Karas growing in these two habitats each from Lipis, Pahang and Sepang, Selangor areas in Malaysia; under the control and induced treatments. The parameters studied include wet and dry weight of 50 matured leaves, iron and zinc elemental contents in leaf, iron and zinc uptakes from soil, and leaf and soil moisture contents. Iron and zinc were analysed in Karas leaves and soil by using Instrumental Neutron Activation Analysis (INAA) technique.
Field investigation on the operation of an industrial fluidized bed paddy dryer of 25 t/h capacity available in a processing complex of Padiberas Nasional Berhad (BERNAS) of Malaysia was carried out to assess its drying characteristics, energy consumption and quality of product during two paddy harvesting seasons. A grain drying simulation model was used to predict dryer performance which can be used as a basis for improving drying operations. For the first season (August-September), average drying rate was found to be 538 kg moisture/h to reduce moisture content (mc) from 36.98± 0.89% dry basis (db) to 27.58±0.79% (db) at 100-120°C of drying air temperature with a feed rate (capacity) of 7.75 t/h. In the second season (February-March), average drying rate was found to be 435 kg moisture/h to reduce mc from 28.14 ±0.68% (db) to 22.54 ± 0.69% (db) at 78-90°C drying air temperature with a feed rate of 9.5 t/h. The thermal and electrical energy consumptions were obtained as 7.57 and 0.97 MJ/kg water removed, respectively, for the first season, while 5.92 and 1.2 MJ/kg water removed for the second season. Higher head rice yield and whiteness and lower milling recovery were achieved during the first season than the second season at acceptable milling degree and transparency. Meanwhile, simulation results indicated that the dryer performed better in terms of increased drying capacity during the second than the first season; the dryer could be operated at 150°C to achieve almost double throughput capacity up to 20 t/h for the second season, while for the first season, high mc hindered the capacity to be at or below 7.75 t/h even when using higher a temperature of 160°C to reduce moisture to the desired final moisture of 24-25% (db).

Population growth and rise in per capital income have influenced the demand for convenience foods and a meat protein-rich diet. The per capital consumption of beef which had increased from 3.89 kg in 1980 to 5.49 kg in 2006 (DVS, 2006/2007) had resulted in an increased in demand for beef at the rate of 6.2% annually. The local beef production although recorded a 2.5% increased over the last 10 years, is still unable to meat the increasing national demand for beef. In 2008, local production of beef is about 38,250 mt. could only meet about 26.7% of the national demand (DVS, 2008). The gap between supply and demand for beef is expected to widen in the next decades unless efforts is been made to accelerate local production. The lack of number of quality breeding stocks and unorganized breeding system had been the major factors that contribute to the slow growth of the local beef industry.
This study aim to evaluate antimicrobial efficacy of sodium hypochlorite (NaOCl) and ozonated water against Enterococci faecalis biofilm. The bacterial biofilm was exposed to 2.62%, 1.31% NaOCl and 0.1 ppm ozonated water over a range of time periods. The presence of viable cells was determined by enumeration of colony forming units (CFU). All experiments were repeated four times (n=4). The effectiveness of the agents was compared using nonparametric Kruskal- Wallis test. The result revealed that 2.62% of NaOCl can completely kill E. faecalis biofilm in 15 minutes whereas 1.31 % NaOCl required a longer time to produce such effect. 0.1 ppm ozonated, however, did not exhibit any antimicrobial effect within the period of time tested. From this study, it can be concluded that 0.1 ppm ozonated water was not comparable with 2.62% and 1.31% NaOCl in antimicrobial efficacy against E. faecalis biofilm.
There has been a significant increase in research on probiotics-associated health benefits in the last 20 years. Many studies carried out in vitro and clinically show that consumption of probiotics inhibits the growth of pathogenic microorganisms. Furthermore, the consumption of probiotics also enhances the host immune response and decreases the levels of carcinogenesis-inducing enzymes. These positive outcomes have led to the use of probiotics in prevention and treatment of infectious diseases like bacterial or antibiotic associated diarrhea, chronic inflammatory bowel diseases and colon cancer. This review summarises literature pertaining to mechanistic actions of probiotics in improving the well-being of hosts.
A recently published meta-analysis showed that each additional serving of rice increased risk of type 2 diabetes mellitus (DM) by an alarming 11%. We investigated whether this phenomenon is seen in the Malaysian population by studying the effect of rice intake and added sugar consumption on fasting plasma glucose (FPG) and fasting triacylglycerol (TAG).
The production of ethanol, from glucose in batch and fed batch culture, was investigated. In the fed batch culture, the glucose feeding was added into the culture at 16th hour of fermentation. The effects of different glucose concentration feeding rates on ethanol fermentation were investigated for fed batch culture. The 2gL-1hr-1 glucose concentration feeding rate was found to give higher ethanol yield (2.47 g ethanol g glucose-1), with respect to substrate consumed as compared to 8 gL-1hr-1 (0.23 g ethanol g glucose-1) and 4 gL-1hr-1 (0.20 g ethanol g glucose-1). The ethanol yield with respect to substrate consumed obtained in batch culture was 0.81 g ethanol g glucose-1. The fed batch culture at 2 gL-1hr-1 glucose concentration feeding rate was proven to be a better fermentation system than the batch culture. The specific growth rate, specific glucose consumption rate and specific ethanol production rate for the fed batch fermentation, at 2 gL-1hr-1 glucose concentration feeding rate, were 0.065 hr-1, 1.20 hr-1 and 0.0009 hr-1, respectively.
