Introduction: The aims of this study were to determine the proximate composition, functional properties and antioxidant activity of pumpkin seeds and rind. Besides, the effects of dietary fibre in pumpkin seeds and rinds on bread qualities and properties were evaluated. Methods: Formulations for bread substituted with 0%, 5% and 10% pumpkin seed and rind, respectively were produced. Sensory evaluation of the prepared bread samples for such attributes as appearance, aroma, flavour, texture and overall acceptability was undertaken. The physical properties of the bread samples, including dough expansion, loaf volume, crumb colour and bread texture, were determined. Proximate analysis and determination of antioxidant activity of the bread samples were also conducted. Results: Crude fibre of the pumpkin seeds and pumpkin rinds was high at 31.48% and 14.83%, respectively. The total phenolic compound (TPC) and DPPH radical scavenging activity for the pumpkin rinds were 38.60 mg GAE/ 100 g dry weight and 69.38%, respectively, which were higher than those of pumpkin seeds. A 5% level of pumpkin rind bread gave the best overall acceptability and sensory attributes, followed by 5% pumpkin seed bread. Total dietary fibre, total phenolic compound and DPPH radical scavenging activity in breads substituted with 5% pumpkin seed and 5% pumpkin rind flour were higher than the values in control bread. Conclusion: Pumpkin seeds and rinds can be used as dietary fibre sources in bakery.
Kajian ini dijalankan untuk menentukan kesan perencatan fi tat terhadap bioavailabiliti kalsium (Ca), ferum (Fe) dan zink (Zn) dalam produk kacang soya tempatan terpilih. Fitat menyebabkan kesan perencatan terhadap penyerapan mineral seperti Ca, Fe dan Zn dengan membentuk kompleks yang tidak larut dan tidak dapat dicernakan. Kesan perencatan fi tat terhadap bioavailabiliti mineral seperti Ca, Fe dan Zn telah dianggarkan dengan nisbah molar fi tat kepada mineral. Kandungan fi tat ditentukan dengan menggunakan kaedah pertukaran anion dan kandungan mineral ditentukan dengan Spektrofotometer Serapan Atom (AAS). Produk kacang soya dibeli dari pasar malam dan gerai makanan yang terletak di Cheras dan Sri Rampai, Kuala Lumpur. Setiap sampel yang dibeli dari kedua- dua lokasi dianalisis secara duplikat. Kajian ini mendapati kek soya dan kesemua masakan yang mengandungi tempe tidak mempunyai kandungan fi tat. Ini mungkin disebabkan oleh kehadiran R. oligosporus yang menghasilkan fi tase lalu menghidrolisiskan kandungan fi tat semasa proses fermentasi tempe. Terdapat lima jenis sampel makanan yang mempunyai nisbah molar fi tat/Ca > 0.24, sepuluh jenis sampel makanan dengan nisbah molar fi tat/ Fe > 1, lapan jenis sampel makanan mempunyai nisbah molar fi tat/ Zn > 15 dan satu jenis sampel makanan mempunyai nisbah molar [fi tat x Ca]/ Zn > 200. Keputusan nisbah molar fi tat/ mineral dari kajian ini menganggarkan bioavailabiliti Ca, Fe dan Zn yang rendah. Kesimpulannya, kek soya dan masakan mengandungi tempe mempunyai bioavailabiliti mineral yang tinggi manakala tau-hoo pok bakar mempunyai bioavailabiliti mineral yang rendah.
The Nipah virus was first discovered in 1999, following a severe outbreak of viral encephalitis among pig farm workers in Malaysia. The virus was thought to have spread from Pteropus bats to pigs, then from infected pigs to humans by close contact. Mortality of the disease was high at about 40%. The main necropsy finding was disseminated microinfarction associated with vasculitis and direct neuronal involvement. Relapsed encephalitis was seen in approximately 10% of those who survived the initial illness. Since its first recorded emergence in peninsular Malaysia, 10 outbreaks of Nipah virus encephalitis have been reported in Bangladesh and West Bengal in India. The outbreaks occurred from January to May, with Pteropus giganteus as the reservoir of the virus. In Bangladesh, evidence indicated that the virus transmitted directly from bats to human, with human to human transmission as an important mode of spread. The mortality of the illness was higher in Bangladesh which stood at around 70%. This was likely to be due to genetic variation of the virus.

Vapour pressure deficit (VPD) analysis introduces an approach to develop a better basis for the control of the environment of lowland greenhouses in Malaysia. The study of vapour pressure deficit (VPD) is to show air moisture conditions for plant production while taking into account different temperature levels. The purpose of this project is to develop a real-time automatic temperature and relative humidity control system in the lowland tropical greenhouse using a PIC16f876A microcontroller. The controller will then be used to monitor the temperature, relative humidity and VPD in the planting of Chili Kulai (Titisan 15). The fertigation system was introduced to the greenhouse to fertilize and irrigate the plant as well as to provide moisture to the environment. A swamp cooler was used to bring down the temperature and increase moisture content in the greenhouse. Ventilators were installed to remove the heat in the greenhouse. The study was carried out in an experimental greenhouse located at the Institute of Advanced Technology, Universiti Putra Malaysia (UPM).
Cardiac concussion is a sudden, direct blunt trauma cause to the chest which led to death. However, there are patients who did not completely fulfil this definition. We report two cases which did not fit into the definition domain. Two male patients presented to Emergency Department with moderate anterior chest pain after motor vehicle crash showed transient anterior ST segment elevation at chest lead V2 and V3 with raised creatine kinase and normal troponin T. The electrocardiogram changes fully resolved after 24 hours. Both patients were discharged uneventfully after 24 hours monitoring in Emergency Department short-stay ward. Conventional definition of cardiac concussion (commotion cordis) and cardiac contusion may be unsuitable to describe these cases. Therefore, we propose the diagnosis of focal
cardiac concussion. We also highlighted the ability of Emergency Department to manage these patients in short-stay ward.
Keywords: commotio cordis, chest pain, nonpenetrating, electrocardiography
The fatty acid composition and trans fatty acids (TFA) contents of samples of five Malaysian cream crackers biscuit brands were determined by gas-liquid chromatography, using a 60 m Supelco SP2340 fused silica capillary column and flame ionization detection. The identities of the fatty acids were established by comparing their retention times with authentic standards from Supelco. The results were expressed as relative percentages. The total saturated fatty acids (SFA) in the samples ranged from 48.90% to 54.87% of total fatty acids. As for the polyunsaturated fatty acids (PUFA), the total PUFA in the samples ranged from 9.97% to 11.73% of total fatty acids. Total trans fatty acids (TFA) ranged from 0.17% to 0.77% of total fatty acids. The monotrans 18:2 tc or 18:2 ct isomer content ranged from 0.07% to 0.10% of total fatty acids and the ditrans 18:2 isomer (9t, 12t) was not detected. The results indicate that all the fat sources of the 5 sample crackers biscuit brands were palm oil based.
The addition of ribose to minced chicken or minced pork followed by heating at 95oC yielded minced
meat with different pH, colour (CIE L*, b*) and absorbance values that can be used as indicators for species differentiation. The higher intensity of the Maillard reaction parameters in minced chicken was due to the higher protein and lysine contents, and the presence of more water-soluble proteins within the minced chicken during heating. Cluster analysis using Maillard reaction parameters showed that the two types of minced meat could be classified into two different groups. A confidence interval (95% confidence) analysis revealed that the absorbance, CIE L* values, and CIE b* values could be used as indicators for differentiation between the two types of minced meat, as the intervals between these Maillard reaction parameters for the two minced meats were far apart.
The aim of this study was to investigate the oxidative stability, antioxidant activity and fatty acid composition of 2 minutes microwave pre-treated kenaf seed oil (MKSO) in comparison with the untreated kenaf seed oil (KSO) under accelerated storage for 24 days. Results obtained on oxidative stability for both KSO and MKSO by the end of storage with PV were 9.83 meq O2 /kg and 8.97 meq O2 /kg, respectively; p-Anv were 17.28 and 13.48, respectively; TOTOX value of 36.94 and 31.42, respectively; IV value were measured 84.50 g of I2 / 100 g and 84.34 g of I2 / 100 g oil, respectively; FFA value of 5.67 mg KOH/100g oil and 5.14 mg KOH/100g oil, respectively. Aside from that, the antioxidant activity in MKSO was better than KSO. For the fatty acid composition, the oleic and linoleic acids were affected significantly throughout storage for both KSO and MKSO. MKSO presented a better overall oxidative stability, antioxidant activity and retained higher content of MUFA and PUFA significantly (p< 0.05) upon accelerated storage.
About 60% of people with mental illness developed co-morbid medical and physical illness that invariably worsens their lives. However, most of the studies regarding this issue were done either in the out-patient or community settings, ignoring long stay inpatients. Locally, no data exists among long stay patients in psychiatric institutions. The aim of this retrospective study was to look at the prevalence of physical illness among long-stay patients and to compare the occurrence of physical illness before and after admission to the psychiatric institution. We found that 85 (63.4%) out of 134 subjects there was suffering with co-morbid physical and medical illnesses. There were 33 (24.6%) subjects with hyperlipidaemia, 22 (16.4%) subjects with hypertension and 17 (12.7%) subjects with diabetes. Approximately 75 (55.9%) subjects developed medical illness after admission. In conclusion, long-stay psychiatric patients are at a high risk of developing medical problems that tends to begin after admission to the psychiatric institution.

The objective of this study was to evaluate the effects of solid-to-solvent ratio (1:5. 1:10, 1:15 and 1:20) on the extraction of phenolic compounds (TPC and TFC) and antioxidant capacity (ABTS and DPPH radical scavenging capacity) of P. niruri. Solid-to-solvent ratio showed a significant effect for both phenolic compounds (TPC and TFC) and antioxidant capacity (ABTS and DPPH radical scavenging capacity) with 1:20 was the condition for extracting the highest of phenolic compounds (TPC and TFC) with a value of 5788.7 mg GAE/100 g DW and 1906.5 mg CE/100 g DW, respectively and exhibited high antioxidant capacities (ABTS and DPPH radical scavenging capacities) with a value of 0.820 mM and 1.598 mM, respectively among the four levels studied. TPC was positively and significantly correlated with ABTS and DPPH (r=0.999 and r=0.999) under the effects of solid-to-solvent ratio as compared to TFC, positively and strongly correlated (r=0.865 and r=0.868) with ABTS and DPPH.
This study aimed to determine and compare antioxidant components and antioxidant capacity in different parts (skin, pulp, mace and seed) of nutmeg. Freeze dried samples were extracted using 80% methanol, while Folin-Ciocalteu assay was employed to determine total phenolic content, aluminium chloride assay was applied to determine total flavonoid content and ascorbic acid was assessed by titrimetric method. Antioxidant activities were evaluated by ferric reducing antioxidant power and trolox equivalent antioxidant capacity (TEAC) assays. Results revealed that nutmeg seed contained the highest TPC followed by mace, skin and pulp. Similar observation was also found for TFC. The highest ascorbic acid content was found in nutmeg mace, while the lowest was in its pulp. For antioxidant activity, nutmeg seed possessed the highest FRAP and TEAC values, while nutmeg pulp had the lowest as compared to other parts. Phenolic compounds in nutmeg samples have exhibited strong correlation with antioxidant capacity. Therefore, nutmeg is a potential functional food with high antioxidants, especially nutmeg seed. Phenolic compounds in nutmeg samples have exhibited strong correlation with antioxidant capacity. Therefore, nutmeg is a potential functional food with high antioxidants, especially nutmeg seed.
The study aimed to evaluate the quality of the hybrid
layer form by three different adhesive systems. Class V
cavities were prepared on the buccal surface of fourty
extracted human premolars. The prepared teeth were
randomly assigned into four groups according to the
adhesive system and application mode. The systems
were: Optibond S (OS, total-etch); Optibond Versa (OV,
two-bottles, self-etch); Single Bond Universal (SBU,
one-bottle, self-etch) and Single Bond Universal with
etchant (SBU + etchant). All cavities were restored with
composite (Filtek Z350XT). The samples were sectioned,
polished and pretreated to remove minerals, protein
and water prior to SEM evaluation. From the images,
thickness of the hybrid layers was measured. Present of
resin tags and adaptation failure were also recorded. The
data obtained were analyzed using ANOVA, Dunnett’s
T3, Kruskal-Wallis and Mann-Whitney tests. OS group
showed the highest average hybrid layer thickness (4.34
µm), followed by SBU + etchant (3.06 µm), OV (1.91 µm)
and SBU (0.95 µm). Both adhesive and cohesive failures
were observed in SBU group. Present of prominent resin
tags were seen in both OS and OV groups. In conclusion,
all the investigated adhesive systems were able to perform
distinguishable actions as shown in micro-morphological
alteration and hybrid layer thickness. Two-bottles, selfetch
adhesive (OV) was proven to produce negligible
adaptation failure compared to other adhesive systems in
the present study. Combined all-in-one adhesive (SBU)
was found to render a superior bonding performance in
total-etch mode comparing to self-etch mode.
The study was undertaken to determine and compare the sodium and potassium contents in
selected salts (table salt, coarse salt, French sea salt, Himalayan pink salt and bamboo salt)
and sauces (light soy sauce, sweet soy sauce, chili sauce, tomato sauce and mayonnaise).
Findings of the present study showed that the sodium content of salts was highest in table salt
(35870.0 mg/100 g) and lowest in French sea salt (31235.0 mg/100 g), whereas the potassium
content was highest in bamboo salt (399.4 mg/100 g) and lowest in table salt (43.7 mg/100
g). There was no significant difference between sodium amounts of the salts. Bamboo salt
was significantly higher in potassium than other salts. The ranking of sodium and potassium
in sauces was similar, where light soy sauce contained the highest amount (4402.0 and 395.4
mg/100 g) and mayonnaise contained the least (231.3 and 63.6 mg/100 g). Both sodium and
potassium contents of light soy sauce were significantly higher than other sauces. Bamboo salt
is a better choice instead of other salts in terms of the potassium level. Among sauces, although
light soy sauce is high in potassium; however, its high sodium has offset the beneficial effect
of potassium.
A total of 306 Malaysian university students and staff were surveyed to ascertain the physical and emotional effects of the polluted haze on them. All subjects completed self-reported questionnaires. Analysis of the results indicated that the majority of subjects reduced their outdoor activities and sports, and also reported an increase in emotional and physical health problems. The results indicated that there was a general increase in emotional problems such as feeling depressed, lacking in energy, not feeling like doing anything, feeling anxious and afraid, difficulty sleeping, feeling agitated and irritable, and having no appetite. There was also an increase in physical symptoms such as itchy or red eyes, itchy or running nose, dry throat/cough, headaches, nausea, and fever. This study indicated that emotional and behavioural problems are just as common during the haze, when compared with physical health problems. The study also suggests that there are a broad range of problems which health care and human resource departments need to be aware of and take precautions to minimize during a haze.
Stigma is conceptually broad and culturally variable. Understanding stigma from the conceptual theories, culturally application based on the word stigma in other languages, the definition of stigma and its synonyms, as well as the medical implications in other stigmatized disease such as AIDS, will help us to understand the complexity of stigma in epilepsy. This review investigated the meaning and types of stigma from different perspectives, leading to staging stigma into 5 levels, i.e. social identity, stereotype, prejudice, discrimination and social disability. In addition to the conventional categorization of stigma into social, felt, self-perceived or internalized stigma, new categories of stigma i.e. personal and general attitudes towards epilepsy based on a newly developed Public Attitudes Toward Epilepsy (PATE) scale was introduced. Courtesy stigma was further elaborated in related to Asian culture. Based on well-established and recently developed theories, the causation and impact of epilepsy stigma was discussed in an Asian context, especially from the aspects of language and society values which are culturally specific. Integrating these theories of causation, illness and stereotype perceptions were proposed to be the mediating mechanism of stigma, which led to the development of a practical and multi-dimensional stigmatization model, aiming to guide, widen and deepen the scope of future stigma research in epilepsy. Using the established model, together with review of related studies, research priorities in epilepsy stigma research especially in Asia focusing on five aspects, i.e. expanding population studies especially on significant others, understanding stigma from personal attitude perspective, investigating the cultural and social causation of stigma, and the impacts of stigma on patients as well as the family members, were proposed.
The aim of the study was to assess the association between past fluoride exposures from ingested toothpaste and current fluorosis manifestations in 10- 11 year old index subjects. Fluorosis was assessed with the Dean’s Index in 1343 10-11 year old index subjects. Two hundred index subjects who had younger 4-5 year old siblings were sub sampled and fluoride exposures from ingested toothpaste in their younger siblings (proxy subjects) were determined. The values for the fluoride ingested per brushing of the proxy subjects were utilised together with past frequency of toothbrushing of index subjects to extrapolate on the past exposure of index subjects. The mean extrapolated past fluoride exposure from ingestion of toothpaste was highly variable; 671.7 ug ± 739.3 ug (sem= 56.9). It was higher in the subjects with fluorosis (697.3 ug) than in those without fluorosis (646.89 ug) but differences were not of statistical significance. This approach of extrapolation has not been reported elsewhere and need to be validated. The implications of the present methodology to estimate past fluoride exposure is discussed.
Tendon is a dense connective tissue that connects muscle to bone. Tendon can adapt to mechanical forces passing across it, through a reciprocal relationship between its cellular components (tenocytes and tenoblasts) and the extracellular matrix (ECM). In early development, the formation of scleraxis-expressing tendon progenitor population in the sclerotome is induced by a fibroblast growth factor signal secreted by the myotome. Tendon injury has been defined as a loss of cells or ECM caused by trauma. It represents a failure of cells and matrix adaptation to mechanical loading. Injury initiates attempts of tendon to repair itself, which has been defined as replacement of damaged or lost cells and ECM by new cells or new matrices. Tendon healing generally consists of four different phases: the inflammatory, proliferation, differentiation and remodelling phases. Clinically, tendons are repaired with a variety of surgical techniques, which show various degrees of success. In order to improve the conventional tendon repair methods, current tendon tissue engineering aims to investigate a repair method which can restore tissue defects with living cells, or cell based therapy. Advances in tissue engineering techniques would potentially yield to a cell-based product that could regenerate functional tendon tissue.
Objectives: This study was carried out to determine the nutritional status of primary
school children aged 6 to 11 years in Sepang District and to compare the results with a
similar study carried out in 1999. Methods: This cross-sectional study was carried out in
Sepang District using stratified random cluster sampling technique. A pre-tested, structured
questionnaire was used to collect the data. Weight was recorded using a digital bathroom
scale TANITA model HD-309 and height was measured by using a SECA Body meter
Model 208. Body mass index (BMI) was calculated as weight in kilograms divided by the
square of height in meters. Classifications of the nutritional status of respondents was
based on WHO classification 1983 and 1995. Data were analysed using SPSS. Results:
The overall mean BMI for the 1,910 respondents was 16.8 (95% CI= 16.67 - 16.99;
SE=0.08). The median BMI was 15 .7 ranging from 9.51 to 36.75 kg/m2. The majority
(84.4%) had normal weight-for-age status, 7.6% respondents had weight-for-age status
below -2 SD of the NCHS-WHO median and 8.0% had weight-for-age status above +2 SD
of the NCHS-WHO median. The prevalence of underweight and overweight was significantly
higher in the males compared to the females (p< 0.05). There was a significant association
between underweight and ethnicity (p< 0.05). The majority (90.3%) had normal heightfor-
age status, 8.8% had height-for-age below - 2 SD of the NCHS-WHO standard median
and 0.9% had height-for-age above 2 SD from the NCHS median. The prevalence of
stunting was significantly higher in the male (10.3%) as compared to 7.4% in the females
(X2 = 5.11, P = 0.02). The majority (81.4%) of the respondents were within the normal
weight-for-height, 3.4% were wasted (weight-for-height was below - 2 SD of the NCHSWHO
median) and 15.2% of the respondents were obese (weight-for-height that is more
than +2 SD of the NCHS-WHO median). The prevalence of wasting was higher in the
females (4.1 %) compared to males (2.8%). The prevalence of obesity was slightly higher
in the males (15.4%) compared to females (14.9%). Conclusion: The overall nutritional
status of primary schools children is good. However, there still exists pockets of population
in Sepang where chronic and acute forms of undernutrition persist in these children.
The Malaysian fish production is about 1.5 million metric tonnes and 86.9% of this comes from the marine sector and 13.1% from the inland sector. This included fish production by capture and culture. (DOF, 2002). Fisheries genetic resources need to have a value in terms of economic, ecological and social uses and they need to characterized. This is the mandate to FAO and it is also necessary for fisheries management and aquaculture development. The vast aquatic diversity that exists in Malaysia consist of numerous taxa of marine and freshwater fishes, crustaceans, mollusks, plants and animals. These figures could be an underestimate to the actual figure. The levels of genetic diversity includes ecosystems, communities, population, genotypes and individual genes. A knowledge of the genetic background of a species and its population structure is essential for its management, breeding and conservation programmes in fisheries. Problems like how to choose the right candidates for breeding, identifiying and monitoring lines, families and individuals, monitoring and control of inbreeding, inheritance of simple traits and genetic improvement through selection for favourable gene and gene combinations can potentially be answered through the use of molecular markers in the management of fisheries genetic resources.
