    Twenty-four children under the age of 10 years with femoral shaft fractures were treated by early immobilization of fracture and application of hip spica cast. The average hospital stay was 3.5 days. The average shortening at time of fracture union was 15 mm. The average time of follow up was 6.7 months. All fractures healed, except for one, in an acceptable position. The average shortening at last follow up was 9.5 mm and the average overgrowth up to the time was 6 mm. There was no incidence of refracture, joint stiffness or any pressure sore.

    Moringa oleifera is a plant with various benefits to mankind from its root until leaves.
    From food to biofuel applications, all parts are useful for daily uses. In this research, the pod husk
    was examined to determine the possibility of producing ethanol. The pod husks were dried and used in
    two forms; one is grinded into powder, and the other is cut within 5 x 5 x 2 mm. About 10 grams of
    Moringa oleifera pod husk was put into a conical flask and added with distilled water up to 250 mL.
    The pre-treatment was made by adding an alkaline solution, NaOH, where the pH of the sample was
    adjusted to (4.5, 5.0, and 5.5) using H2SO4. The samples were autoclaved at a temperature of 120°C
    for 2 hours before the samples were cooled to room temperature (25+/-2oC). Baker’s yeast
    (Saccharomyces cerevisiae) was prepared with different concentrations (1g, 5g, and 10g) and added
    to the samples for fermentation process that took place in the incubator shaker at a temperature of
    36°C, for a period of 72 hours. The bioethanol concentration was measured using High Performance
    Liquid Chromatography (HPLC) with a refractive index detector and REZEX ROA-Organic Acid
    HPLC Column using 0.05 N H2SO4 as the mobile phase. The bioethanol produced from Moringa
    oleifera pod husk was 8.400 g/L using 1g/L yeast, and the fermentation took place at pH 4.5 for the
    sample size of 5 x 5 x 2 mm. The results showed that Moringa oleifera pod husk can be introduced as
    a new material for bioethanol production in Malaysia and other tropical countries where this tree is
    available

    Ability to possess ball during football matches are link to success. Domination of Johor Darul Ta’zim FC (JDT FC) in recent years in Malaysia Super League impressed many. The aim of this study was to compare the performance between JDT FC and their opponents in Malaysia Super League 2015 season. Successful and unsuccessful passes, ball possession rates, attempt on goal, shot on target, and goal scored were selected as Performance Indicator (P.I) in this study. Twelve matches from Malaysia Super League (MSL) season 2015 were selected. The video of 12 matches was obtained from Media Prima Sdn. Bhd., www.youtube.com and live recordings. Longo Match 1.0 match analysis software was used for post-coding. Kolmogorov-Smirnov Z was used to analyses the differences while Spearman's rho correlation test was utilized to determine the correlation. Percentage of successful passes (p=0.034), ball possessions rate (p=0.000), and goal scored (p=0.002) were significantly different between JDT FC and their opponents. There were also positive correlations between possessions and all variables except for unsuccessful passes. This study concluded that in Malaysian football matches, high percentage of successful passes, and high rate of ball possessions influenced total shot in football game.

    Atherosclerosis, the cholesterol deposition in and around cells of the intimal layer of the aorta, has been recognized as one of the main causative factors for cardiovascular diseases. Intensive research has been carried out throughout the world but the precise atherogenesis has yet to be fully understood, though hypercholesterolaemia is considered to be the prime risk factor. The aim of the study was to evaluate the effect of high cholesterol diet consumption on the formation of atherosclerosis in vivo. Three groups of adultWhite New Zealand male rabbits (six animals per group) were used in this study. Except for one group which acted as a control (K), the other two groups were given 1% and 2% high cholesterol diet respectively for 10 weeks. At the end of the experiment, blood samples were taken from the marginal ear vein for plasma cholesterol estimation. The animals were sacrificed and the aorta was excised for histomorphometric analysis. The result shows that despite no significant differences in plasma cholesterol levels being observed between the groups treated with 1% and 2% cholesterol, high cholesterol consumption was able to induce hypercholesterolaemia significantly (p

    It is noted that nowadays, halal products are gaining wider recognition as a new benchmark for safety and quality assurance. As a consequence of these additional pigment needs, the demand in isolated natural colorants has increased as compared with synthetic dyes. The aim of the research is to explore new sources of pigments to be used as halal food colorants. This quest is not only directed in finding natural alternatives for synthetic dyes, but also with the aim to discover new taxons for the pigment production, for instance from microalgae. Therefore, a total of six freshwater algae species were evaluated quantitative and qualitatively using HPLC for carotenoids pigment. Three main carotenoids were identified in Chlorella fusca, Chlorella vulgaris, Selenastrum capricornutum, Pandorina morum, Botryococcus sudeticus and Chlorococcum sp. which are lutein, β-cryptoxanthin and β-carotene. The ratio of these carotenoids varies between species where lutein was detected substantially higher in Chlorella fusca (69.54±11.29µg/g DW); β-cryptoxanthin in Pandorina morum (1.24±0.33 µg/g DW) whereas β-carotene in Chlorella vulgaris (18.42±9.2 ug/g DW). The significant outcome of the research will be new findings of new natural carotenoid pigment sources as potential food colorants and bioactive compounds which can be beneficial to halal health promoting products industry, food products and dye technology which covers not only the Shariah requirement, but also the hygiene, purification and safety aspects.

    To explore the association between social
    support and stress levels in preclinical and clinical dental
    students in Malaysia. Method: A cross sectional survey
    of dental undergraduate students was conducted at the
    Faculty of Dentistry, University of Malaya, Universiti
    Kebangsaan Malaysia and Universiti Sains Malaysia.
    Stress was measured using the Dental Environment Stress
    (DES) questionnaire. A DES-32 item was used to measure
    stress for the clinical students and DES-16 item for the
    preclinical students. Four questions were used to measure
    social support. The total stress scores were standardized
    for comparison purposes. Results: A total of 357 (79.7%)
    preclinical and 417 (71.8%) clinical undergraduate dental
    students responded to the questionnaires. The clinical
    students experienced higher stress [mean standardized
    DES score = 72.63, SD = 10.64] than preclinical students
    [mean standardized DES score = 70.19, SD=12.01]. The
    two most stressful items reported by preclinical students
    were “fear of failing” and “examination and grades”.
    Among clinical students, the two most stressful items related
    to academic were “completing course requirement” and
    “fear of failing course” and items related to clinical session
    were “fear of being barred due to the clinical schedule”
    and “patients late or absent”. Multiple regression analyses
    revealed that low stress levels among preclinical students
    were significantly associated to a lot of contact with
    students of the same course. Conclusion: To some extent,
    social support does play a role in explaining differences in
    perceived stress, in particular among preclinical students.

    Fish has been recognized as a source of potent allergens both in food and occupational allergy. Lutjanus argentimaculatus (red snapper) and Lutjanus johnii (golden snapper) locally known as merah and jenahak, respectively, are among the most commonly consumed fish in Malaysia. The objective of this study is to identify the IgE-binding proteins and major allergens of these species of fishes. Extracts of both fish species were prepared and fractionated by sodium dodecyl polyacrylamide gel electrophoresis (SDS-PAGE). IgE binding patterns were then demonstrated by immunoblotting using sera from patients allergic to the fishes. The raw extracts of both fish produced 26 protein bands. Both species of fishes had similar protein profiles. In cooked extracts, several protein bands in the range of about 40 to 90 kD which were present in the uncooked extracts appeared to be denatured and formed high molecular weight complexes. The immunoblotting of golden snapper and red snapper revealed 16 and 15 various IgE-binding bands, in the range of 151 to 12-11 kD, respectively. A 51 kD protein was identified as a major allergen for both fishes. A 46 kD protein was also demonstrated as a major allergen in golden snapper and a 42 kD protein was also seen as a major allergen in red snapper. A heat-resistant protein of ~12 kD which is equivalent in size with fish parvalbumin was demonstrated only as minor allergen for both fishes.

    The effects of castration with/ without testosterone replacement in male rats, and ovarectomy with oestrogen replacement in female rats, on serum lipids were studied. Simultaneous feeding with diets fortified with 20% weight/ weight (w/ w) soybean oil (Sb) or palm oil (P0) were done to determine the influence of these oils on serum lipids in castrated and sex hormone replaced rats. Two month old male and female Rattus norwegicus rats were given the above treatment for 4 months, and their sera assayed for lipid profile. Castration increased HDL-cholesterol (HDLchol) and total cholesterol (Tchol) concentrations. Testosterone or oestrogen replacement in male and female rats respectively increased HDLchol and decreased LDL-cholesterol (LDLchol) concentrations. Testosterone replacement also decreased Tchol concentration back to noncastrated levels, and reduced serum triglycerides (TG) to lower than non-castrated levels. Addition of Sb or P0 to the diet increased the LDLchol in the testosterone or oestrogen replaced male and female rats, but there was no difference between the two groups. P0 raised serum TG of the testosterone replaced group compared to control and Sb groups. In conclusion, testosterone and oestrogen were found to have favourable effects on serum lipids. Sb and P0 did not differ in their effects on lipoprotein cholesterol and Tchol, but P0 raised serum TG as compared to Sb.

    BACKGROUND: There is a lack of evidence with regards to the association between both maternal and child dental anxiety and the mother's perception of her child's oral health-related quality of life (COHRQoL). The aim of this study was to investigate the association of maternal and child dental anxiety with COHRQoL and the effect of demographic factors as moderators in this relationship. In addition, the association between child's dental caries experience and the COHRQoL was also assessed.

    METHODS: A cross-sectional study was conducted involving 1150, 5-6 year-old preschool children in Selangor, Malaysia. Mothers answered a questionnaire on socio-economic status, the Malay-Modified Dental Anxiety Scale to assess maternal dental anxiety, and the Malay-Early Childhood Oral Health Impact Scale to assess COHRQoL. Child's dental anxiety was assessed using the Malay-Modified Child Dental Anxiety Scale via a face-to-face interview prior to oral examination to assess dental caries. Data were analysed using structural equation modelling to assess the relationship between maternal and child dental anxiety and COHRQoL.

    RESULTS: Overall, complete data on 842 mother-child dyads were analysed. The mean scores of total ECOHIS, the child impacts section (CIS), and the family impacts section (FIS) were 17.7 (SD = 4.9), 12.6 (SD = 3.7), and 5.1 (SD = 1.9), respectively. The mean dental anxiety scores for mothers and children were 11.8 (SD = 4.5) and 16.9 (SD = 4.3), respectively. Maternal dental anxiety was associated with the CIS (b = 0.08, p

    In a biological system the product of free-radical induced-lipid peroxidation are conjugated dienes (CDs), lipid peroxides and malondialdehyde (MDA). Its control depends on antioxidant activities. Antioxidant defend the body system by controlling the damage caused by the free radicals. This paper describes lipid peroxidation process and antioxidant activities present in three species of holothuroid obtained from the coastal waters of Terengganu, Malaysia. Among the three species studied, the coelomic fluid of Bohadschia mamorata vitiensis contained the highest level of protein (7.24 + 0.04)g/L. The coelomic fluid of Stichopus badionotus Selenka contained the highest level of superoxide dismutase (SOD) (9.46 + 0.99)X 105 IU/g protein, MDA (16.46 + 1.28)nmol/g protein and total antioxidant activities (AOA) (58.81 + 5.70) %. In Stichopus variegatus Semper the coelomic fluid only demonstrated the highest level of CDs (94.19 + 11.34) RU/g protein compared with the other two species. This preliminary study indicated that some form of antioxidant activities are present in the coelomic fluid of holothuroids.

    The purpose of this study was to evaluate the combined effect of ferrule height and post length on fracture resistance and failure mode of endodontically treated teeth restored with glass fibre posts, composite resin cores and crowns. Ninety human maxillary central incisors were endodontically treated and divided into three groups (n = 30) according to the ferrule heights: 4, 2 and 0 mm, respectively. Post spaces in each group were prepared at 2/3, 1/2 and 1/3 of the root length (n = 10). The specimens were received fibre posts, composite resin core build up and cast metal crowns. After thermocycling, compressive static load was applied at an angle of 135° to the crowns. Two-way analysis of variance showed significant differences in the failure load in the ferrule height groups, no significant differences in post length groups and no significant interaction between ferrule heights and post lengths. More restorable failure modes were observed.

    Children who are born in a community with insufficient micronutrients, particularly iodine in remote rural areas are associated with low intellectual functions and mental retardation. The aim of this cross-sectional study is to determine the mental performance of the schoolchildren in Bario, a highland settlement of the Kelabit people in the district of Baram, Sarawak and to determine its correlation with the availability of iodine in the environment, as well as other micronutrients such as selenium, copper and manganese. A total of 25 schoolchildren in Bario age ranging from 7 to 12 years old participated in the study. Mental performance of the schoolchildren were tested using TONI-2 (Test of Nonverbal Intelligence--second edition), a cognitive ability measures with a response format which eliminates language and reduces motoric and cultural factors. The iodine levels from several wells, soils and salt found in Bario were determined using HPLC (software version 3.05.01) whilst serum levels of selenium, copper and manganese were measured using Graphite Furnace Atomic Absorption Spectrophotometer (GFAAS). The results showed that the median and mode scores of intelligence quotient for Bario were 82 and 75, respectively, whilst median and mode scores of intelligence percentile were 11.0 and 5.0, respectively. The maximum score achieved were at the average level with the quotient score between 90-110. It was found that salt produced from one of the wells in Bario contained high quantity of iodine. Based on standards established by the Trace Elements Laboratory, Roben Institute, University of Surrey, United Kingdom, schoolchildren in Bario are having sufficient blood levels of copper and a high selenium and manganese levels. Despite the remoteness of the study area, the schoolchildren in Bario, Sarawak showed higher mental performance compared to other isolated areas. This is probably correlated with the high micronutrients availability, particularly iodine, found naturally in Bario.

    Breast cancer is the most common cause of deaths and the most frequently diagnosed cancer among women worldwide. This study aimed to determine the prevalence of breast cancer screening, specifically on clinical breast examination, and the predictors of its uptake among women in Malaysia. A cross-sectional study was carried out in five selected districts whereby women aged between 20 to 64 years old, from a total of 1000 households were interviewed. A total of 1192 women responded to the survey of which 53.3% reported had ever done clinical breast examination. Significant associations with clinical breast examination were noted for income and distance from the hospital. These factors should be considered in developing interventions aimed at promoting clinical breast examination. In particular, healthcare providers should be proactive in raising awareness about clinical breast examination among women in Malaysia.

    We report significant enhancements in Er(3+) luminescence as well as in Raman intensity in silver nanoparticles embedded zinc-tellurite glass. Surface enhanced Raman scattering effect is highlighted for the first time in tellurite glass containing silver NPs resulting in an enhanced Raman signal (~10 times). SAED manifest the growth of Ag(0) nanoparticles along the (111) and (200) crystallographic planes having average diameter in the range 14-36 nm. Surface plasmon resonance bands are observed in the range 484-551 nm. Furthermore, four prominent photoluminescence bands undergo significant enhancements up to 3 times. The enhancement is majorly attributed to the local field effect of silver NPs.

    We experimentally investigate the performance of L-band multiwavelength Brillouin-Raman fiber laser (MBRFL) under forward and backward pumped environments utilizing a linear cavity. A short length of 1.18 km dispersion compensating fiber is used as a nonlinear gain medium for both Brillouin and Raman gain. Experimental results indicate that the gain in the copumped laser configuration is higher than the gain in the counterpumped configuration. A stable and constant number of Brillouin Stokes lines up to 23 Stokes, with channel spacing of 0.08 nm and more than 20 dB of optical signal to noise ratio, can be generated as well as tuning over 20 nm in the L-band region from 1570 to 1590 nm. The laser generating the Brillouin Stokes lines exhibits flat amplitude bandwidth and high average output power of 0.8 and 1.6 dBm for the copropagation and counterpropagation pumps, respectively. Moreover, the tuning range bandwidth of the MBRFL can be predicted from the oscillated Brillouin pump gain profile.

    INTRODUCTION: Sound therapy is one of the complementary or alternative interventions for various populations. The intensity of the sounds for sound therapy needs to be properly calibrated to ensure their accuracy and effectiveness. This paper aims to provide a general guideline for calibrating sound files using free software, specifically Audacity®.

    MATERIALS AND METHODS: Six sounds (broadband noise, rain, ocean, waterfall, Quranic chapters Al-Fatihah, and Yasin recitations) were calibrated at the intensity levels of 45, 50, 55, 60, 65, 70, 75, and 80dBA. The sounds were delivered through a pair of Sennheiser HD 280 Pro headphones connected to the Sound Blaster X-Fi Surround 5.1 Pro sound card. The long-term average of the sound pressure level over the time of recording (LAseq) was recorded using the 3M SoundPro Class 1 1/3 Octave RTA sound level meter (SLM). The desired intensity levels were obtained by making adjustments to the sound files via the Audacity® software.

    RESULTS: All sound files were calibrated at the targeted levels as verified by the value of LAseq.

    CONCLUSIONS: Calibration of audio files can be done using a free/open-source software, as all six sound files were successfully calibrated at the targeted levels of 45, 50, 55, 60, 65, 70, 75, and 80dBA. The calibration steps provided in this paper can be easily applied by other researchers for similar purposes, with precautions when calibrating at low levels.
