    Gestational hypertension (GH) is a common disorder during pregnancy that can progress to preeclampsia and cause various subsequent fatal complications. A cluster of enzymes, called matrix metalloproteinases (MMPs), and its specific inhibitors, tissue inhibitors of metalloproteinases (TIMPs), have been reported to be involved in the pathophysiology of GH. The purpose of this study was to examine circulating levels of MMP-9, TIMP-1 and TIMP-2 in pregnant women who had GH and those who were normotensive.

    The Toba supereruption in Sumatra, ∼74 thousand years (ka) ago, was the largest terrestrial volcanic event of the Quaternary. Ash and sulfate aerosols were deposited in both hemispheres, forming a time-marker horizon that can be used to synchronize late Quaternary records globally. A precise numerical age for this event has proved elusive, with dating uncertainties larger than the millennial-scale climate cycles that characterized this period. We report an astronomically calibrated (40)Ar/(39)Ar age of 73.88 ± 0.32 ka (1σ, full external errors) for sanidine crystals extracted from Toba deposits in the Lenggong Valley, Malaysia, 350 km from the eruption source and 6 km from an archaeological site with stone artifacts buried by ash. If these artifacts were made by Homo sapiens, as has been suggested, then our age indicates that modern humans had reached Southeast Asia by ∼74 ka ago. Our (40)Ar/(39)Ar age is an order-of-magnitude more precise than previous estimates, resolving the timing of the eruption to the middle of the cold interval between Dansgaard-Oeschger events 20 and 19, when a peak in sulfate concentration occurred as registered by Greenland ice cores. This peak is followed by a ∼10 °C drop in the Greenland surface temperature over ∼150 y, revealing the possible climatic impact of the eruption. Our (40)Ar/(39)Ar age also provides a high-precision calibration point for other ice, marine, and terrestrial archives containing Toba sulfates and ash, facilitating their global synchronization at unprecedented resolution for a critical period in Earth and human history beyond the range of (14)C dating.

    The current study aimed to explore the public views and expectation about a successful communication process between the healthcare providers/physicians and patients in Penang Island, Malaysia. A cross-sectional study was conducted in Penang Island using a 14-item questionnaire. Statistical Package for Social Sciences (SPSS) software version 15.0(®) were used to analyze the collected data. A nonparametric statistics was applied; the Chi-square test was applied to measure the association among the variables. P-values less than 0.05 were considered statistically significant. A total of N (500) respondents have shown willingness to participate in the study with a response rate of 83.3%. The majority 319 (63.9%) have disclosed to communicate with their healthcare providers in the Malay language and about 401 (80.4%) of the respondents were found satisfied with the information provided by the physician. It was a common expectation by the most of the sample to focus more on the patient history before prescribing any medicine. Moreover, about 60.0% of the respondents expected that the healthcare providers must show patience to the patient's queries. The level of satisfaction with the information shared by the healthcare providers was higher among the respondents with a higher education level. Furthermore, patients with higher level of education expect that physician shouldwell understand their views and medical history to prescribe a better therapeutic regimen.

    The effect of morphology on the plasmonic sensing of the presence of formaldehyde in water by gold nanostructures has been investigated. The gold nanostructures with two different morphologies, namely spherical and rod, were prepared using a seed-mediated method. In typical results, it was found that the plasmonic properties of gold nanostructures were very sensitive to the presence of formaldehyde in their surrounding medium by showing the change in both the plasmonic peaks position and the intensity. Spherical nanoparticles (GNS), for example, indicated an increase in the sensitivity when the size was increased from 25 to 35 nm and dramatically decreased when the size was further increased. An m value, the ratio between plasmonic peak shift and refractive index change, as high as 36.5 nm/RIU (refractive index unit) was obtained so far. An expanded sensing mode to FD was obtained when gold nanostructures with nanorods morphology (GNR) were used because of the presence of two plasmonic modes for response probing. However, in the present study, effective plasmonic peak shift was not observed due to the intense plasmonic coupling of closely packed nanorod structures on the surface. Nevertheless, the present results at least provide a potential strategy for response enhancement via shape-effects. High performance plasmonic sensors could be obtained if controlled arrays of nanorods can be prepared on the surface.

    Planning of energy-efficient protocols is critical for Wireless Sensor Networks (WSNs) because of the constraints on the sensor nodes' energy. The routing protocol should be able to provide uniform power dissipation during transmission to the sink node. In this paper, we present a self-optimization scheme for WSNs which is able to utilize and optimize the sensor nodes' resources, especially the batteries, to achieve balanced energy consumption across all sensor nodes. This method is based on the Ant Colony Optimization (ACO) metaheuristic which is adopted to enhance the paths with the best quality function. The assessment of this function depends on multi-criteria metrics such as the minimum residual battery power, hop count and average energy of both route and network. This method also distributes the traffic load of sensor nodes throughout the WSN leading to reduced energy usage, extended network life time and reduced packet loss. Simulation results show that our scheme performs much better than the Energy Efficient Ant-Based Routing (EEABR) in terms of energy consumption, balancing and efficiency.

    Background: This was a cross-sectional study on the gender differences in weight-control behavior. The strategies used, weight status, weight satisfaction, and proportion of individuals attempting to lose weight among 233 government employees (104 men and 129 women) working in the Federal Government Building in Penang, Malaysia, were assessed.
    Methods: Anthropometric indicators such as body mass index, waist-to-hip ratio, and body fat percentage were measured to determine the subjects’ body weight status. A questionnaire covering the following items was used to assess weight-control behavior: social support, self-monitoring, self-efficacy, outcome expectations, planning, preparation/buying, portion control, social interactions, and cognitive behavioral strategies.
    Results: About 50% of the subjects were classified as overweight. Based on percent body fat percentage, 70% of them were classified as having unhealthy levels of body fat. Women were found to be more dissatisfied with their current weight, and were more likely to attempt weight reduction compared to men. Women reported higher levels of social support for dieting and had better expectations for diet and exercise (P < 0.05). They also reported higher use of weight control strategies. For self-monitoring, although no gender-dependent differences (P > 0.05) were observed, women reported more frequent self-monitoring of diet, whereas men reported more frequent self-monitoring of exercise.
    Conclusion: Health care professionals and researchers should be aware of the different strategies used by men and women in order to plan and/or implement community-wide weight management programmes.

    BACKGROUND: To examine the effects of soy [in the form of textured soy protein (TSP) and soy-nut] on body composition in elderly women with metabolic syndrome (MetS).
    METHODS: A 12-week randomized clinical trial was conducted on 75 women between 60-70 years of age with MetS in rural health clinics around Babol, Iran in 2009. The participants were randomly assigned to one of the three groups of soy-nut (35g/d), TSP (35g/d) and control. Body fat, lean mass and anthropometric indicators were measured before and after intervention, too.
    RESULTS: Participants were classified as overweight and showing android fat distribution. After 12 weeks of intervention, both soy-nut and TSP groups showed an increase of non-significant in lean mass (0.9 and 0.7 kg), hip circumference (0.45 and 0.28 cm), triceps skinfold (TSF) thickness (0.87 and 0.67mm) and reduction in BMI (-0.15 and -0.33), waist circumference (-0.83 and -1.2) and body fat (-1.5% and -1.7%). Significant increase in the mean change of TSF and lean mass was observed in the users of soy-nut compared to the control group (P<0.01, P<0.05).
    CONCLUSION: 12-week intervention of soy had a mild favorable effect on body composition in elderly women with MetS.

    BACKGROUND: Introduction to sexual education in schools was suggested by the Malaysian government as one of the effort taken in the aim to reduce the sexual-related social problems among Malaysian teenagers nowadays. This study was proposed in the aim to determine the rate of acceptance among adolescents on the implementation of sexual education in schools.

    METHODS: This study was conducted using questionnaires distributed to 152 pre-degree students in Faculty of Pharmacy, Universiti Teknologi MARA (UiTM), Kampus Puncak Alam, Selangor, Malaysia. Obtained data were statistically analyzed.

    RESULTS: Almost half (49.3%) of the respondents agreed that sexual education might help to overcome the social illness among school teenagers. Besides, a large number (77.6%) of respondents also agreed that this module should be incorporated with other core subjects compare to the feedback received on the implementation of this module on its own (28.9%).

    CONCLUSION: These results have provided some insight towards the perception of sexual education among the teenagers. Since most of the respondents agreed with this idea, so it might be a sign that the implementation of sexual education is almost accepted by the adolescents.

    BACKGROUND: The need for better healthcare has grown significantly in recent years. In addition, the rising healthcare costs in the U.S. and in many European countries have forced many patients to seek medical treatment abroad, which has created the demand for medical tourism. With little yet known as to the perception of a medical tourist's destination selection, this study aims to explore medical tourist's perception in selecting their destination while going for medical treatment.

    METHODS: Realizing the current need to examine closely the perception of medical tourists, this study had conducted a secondary study to collect data for assessing and identification of the key factors on patient's perception and destination selection criteria.

    RESULTS: The result confirms the existence of a very strong relationship between cost, service quality, treatment types and availability and marketing impact on the perception of the medical tourists' in selecting their medical tourism destination.

    CONCLUSION: This study offers support for the proposed conceptual model and an empirical basis for comparison in future research.

    Malaysia has achieved reasonable health outcomes even though the country spends a modest amount of Gross Domestic Product on healthcare. However, the country is now experiencing a rising incidence of both infectious diseases and chronic lifestyle conditions that reflect growing wealth in a vibrant and successful economy. With an eye on an ageing population, reform of the health sector is a government priority. As in other many parts of the world, general practitioners are the first healthcare professional consulted by patients. The Malaysian health system is served by public and private care providers. The integration of the two sectors is a key target for reform. However, the future health of the nation will depend on leadership in the primary care sector. This leadership will need to be informed by research to integrate care providers, empower patients, bridge cultural gaps and ensure equitable access to scarce health resources.

    BACKGROUND: Long-term glucocorticoid therapy causes secondary osteoporosis leading to pathological fractures. Glucocorticoid action in bone is dependant upon the activity of 11β-hydroxysteroid dehydrogenase type 1 enzyme (11β-HSD1). Piper sarmentosum is a local herb that possesses the ability to inhibit 11-βHSD1 enzyme activity. We aimed to determine the effects of Piper sarmentosum water extract on 11-βHSD1 expressions and activity in the bones of glucocorticoid-treated adrenalectomized rats.

    METHODS: Forty male Sprague-Dawley rats (200-250 g) were used. Twenty-four animals were adrenalectomized and received intramuscular injection of dexamethasone (120 μg/kg/day). They were simultaneously administered with either Piper sarmentosum water extract (125 mg/kg/day), GCA (120 mg/kg/day) or distilled water as vehicle by oral gavage for two months. Eight animals were sham-operated and given vehicle daily, i.e. intramuscular olive oil and oral distilled water.

    RESULTS: Following two months treatment, dexamethasone-treated adrenalectomized rats had significantly lower 11β-HSD1 dehydrogenase activity and higher 11β-HSD1 expression in the femoral bones compared to the sham-operated and baseline group. The rats supplemented with Piper sarmentosum water extract had significantly higher 11β-HSD1 dehydrogenase activity and lower 11β-HSD1 expression in the bones.

    CONCLUSION: The results showed that Piper sarmentosum water extract had the ability to prevent glucocorcoticoid excess in the bones of glucocorticoid-treated adrenalectomized rats through the local modulation of 11β-HSD1 expression and activity, and may be used as prophylaxis for osteoporosis in patients on long-term glucocorticoid treatment.

    Patients who are on prolonged ventilator support in critical care unit present wide variety of complications, which range from reduction in oxygen uptake to various musculoskeletal impairments. Early mobilization and rehabilitation are encouraged to manage these complications effectively. Use of tilt table to motivate early mobilization in the intensive care unit for ventilator practices is not a usual practice. However, this new technique has attracted involvements of clinicians and therapists for its therapeutic benefits to the patient. Herein we describe a case of a seventy eight-year-old male patient who suffered Motor car accident, and was on ventilator support in intensive care unit for more than one month. He underwent treatment using a tilt table protocol with other routine treatment, which benefited him based on clinical as well as physiological variables. For practitioners in intensive care units, this report may offer perceptivity into the alternate practice of early mobilization using tilt table, and for investigators it may promote interest for further studies.
