Fulltext Chocolate: food for moods

Wong SY, Lua PL

Malays J Nutr, 2011 Aug;17(2):259-69.
PMID: 22303579 MyJurnal

Chocolate is a popular food and its consumption has long been associated with enjoyment and pleasure. The effect of chocolate on mood too has long been recognised. Chocolate is thought to have interactions with neurotransmitters which contribute to mood modulation and appetite regulation. However, the evidence in chocolate and mood studies remains highly controversial. As more is known about the influence of chocolate on mood, the reasons for these effects appear increasingly complex and inter-related.

Objective: This interventional study was aimed to investigate the effects of dark chocolate
consumption on anxiety, depression, and stress (ADS) among trainee nurses. Methods: A
parallel and open-label experimental study was conducted. Of the 128 nurses enrolled, only 47 participated in the intervention study (mean age = 20.32 years; ranging from 19 to 22 years old). They were randomly assigned to an intervention group (IG, n = 25) or a control group (CG, n = 22). The IG consumed dark chocolate and CG ingested mineral water for 3 consecutive days. The validated Malay Hospital Anxiety and Depression Scale (HADS) and Depression, Anxiety and Stress Scale (DASS-21) were utilised for measuring ADS levels. Data were analysed descriptively and score comparisons were conducted using non-parametric tests. Results: No significant differences between IG and CG in ADS scores were detected at baseline (all p > 0.05). At post-consumption, ADS score were significantly reduced in IG (all p < 0.01) compared with CG (all p < 0.05). Larger effect sizes among these respondents had also revealed that there were mood-elevating effects of dark chocolate consumption. Conclusion: This study has discovered that 3-day consumption of dark chocolate may alleviate ADS status among trainee nurses suggesting that dark chocolate may have a more prominent role in improving emotional and mood generally. Further investigations are however warranted to confirm this finding.
Effects of Hibiscus sabdariffa L. on serum lipids: a systematic review and meta-analysis

Aziz Z, Wong SY, Chong NJ

J Ethnopharmacol, 2013 Nov 25;150(2):442-50.
PMID: 24120746 DOI: 10.1016/j.jep.2013.09.042

Prevention of cardiovascular disease by modifying its major risk factors, including serum cholesterol levels, is an important strategy. Hibiscus sabdariffa L. has been promoted for reducing cholesterol levels, but its reported impact on cholesterol levels has been inconsistent. The study aimed to assess systematically the evidence and quality of current research on the effect of Hibiscus sabdariffa L. on blood lipids and its adverse effects.
Fulltext Prevalence and antibiotic susceptibility of bacteria from acute and chronic wounds in Malaysian subjects

Wong SY, Manikam R, Muniandy S

J Infect Dev Ctries, 2015 Sep;9(9):936-44.
PMID: 26409734 DOI: 10.3855/jidc.5882

INTRODUCTION: Chronic wounds represent a major health burden worldwide. It has been hypothesized that the polymicrobial nature of wounds plays an important role in their healing process. Thus, a review of pathogen frequency and susceptibility patterns in wounds is necessary to provide appropriate guidelines for antimicrobial usage.
METHODOLOGY: In this study, microbiota and antimicrobial resistance in both acute and chronic wound patients treated at the University of Malaya Medical Centre, Malaysia, were compared. Wound swabs from 84 patients with acute wounds and 84 patients with chronic wounds were collected. The specimens were cultured using standard microbiological techniques. Isolates were then tested for antibiotic sensitivity with the broth microdilution method.
RESULTS: Of 210 pathogenic bacteria isolates, Staphylococcus aureus (49; 23.3%) and Pseudomonas aeruginosa (31; 14.8%) were the most prevalent bacteria found in wounds. Staphylococcus aureus was found significantly more often in patients with chronic wounds (41; 48.8%) than in patients with acute wounds (8; 9.5%), while Staphylococcus epidermidis was found predominantly in acute wounds (15; 17.9%). At the time of study, patients with chronic wounds (58.3%) had received more antibiotic treatments in the past previous 12 months compared with patients with acute wounds (16.7%). In the antibiotic susceptibility test, Staphylococcus spp. revealed highest resistance towards penicillin and ampicillin. Isolates showed no decrease in susceptibility against a number of newly developed antibiotics (linezolid, daptomycin, and tigecycline).
CONCLUSIONS: Our finding showed that bacteria diversity and antimicrobial-resistant strains are more frequently found in chronic wounds than in acute wounds.

Chao TC, Maxwell SM, Wong SY

J Pathol, 1991 Jul;164(3):225-33.
PMID: 1890547

An outbreak of food poisoning resulting in 13 deaths in children occurred in Malaysia during the Chinese Festival of the Nine-Emperor Gods in 1988. The offending food was a Chinese noodle called 'Loh See Fun' (LSF). The source was traced to a factory where a banned food preservative was added to make the LSF. The food poisoning was attributable to aflatoxins and boric acid. The clinical features included vomiting, pyrexia, diarrhoea, abdominal pain, anorexia, giddiness, seizures, and eventual coma. Initially, many presented with a Reye-like syndrome. Eleven post-mortem examinations were performed. The pathological findings included extensive coagulative necrosis of the liver with proliferative 'ductal/ductular metaplasia of the hepatocytes'. Giant cell formation, central vein sclerosis, bile stasis, and steatosis were also noted. There was presence of acute tubular necrosis, superficial upper gastrointestinal erosions, and ensuing encephalopathy. The eventual cause of death is acute hepatic and renal failure.
Fulltext Development of high-performance two-dimensional gel electrophoresis for human hair shaft proteome

Wong SY, Hashim OH, Hayashi N

PLoS One, 2019;14(3):e0213947.
PMID: 30889197 DOI: 10.1371/journal.pone.0213947

The primary components of human hair shaft-keratin and keratin-associated proteins (KAPs), together with their cross-linked networks-are the underlying reason for its rigid structure. It is therefore requisite to overcome the obstacle of hair insolubility and establish a reliable protocol for the proteome analysis of this accessible specimen. The present study employed an alkaline-based method for the efficient isolation of hair proteins and subsequently examined them using gel-based proteomics. The introduction of two proteomic protocols, namely the conventional and modified protocol, have resulted in the detection of more than 400 protein spots on the two-dimensional gel electrophoresis (2DE). When compared, the modified protocol is deemed to improve overall reproducibility, whilst offering a quick overview of the total protein distribution of hair. The development of this high-performance protocol is hoped to provide a new approach for hair analysis, which could possibly lead to the discovery of biomarkers for hair in health and diseases in the future.

Wong SY, Ooi IH, Boyce PC

Bot Stud, 2014 Dec;55(1):51.
PMID: 28510939 DOI: 10.1186/s40529-014-0051-9

BACKGROUND: Haniffia Holttum is a genus of three described species of terrestrial gingers hitherto restricted to Peninsular Thailand and various localities in Peninsular Malaysia.
RESULTS: With generic placement confirmed using nrITS, trn K and mat K plastid sequence data, Haniffia santubongensis S.Y. Wong & P.C. Boyce is described as a taxonomically novel species representing a new generic record for Borneo, to where it is endemic to Mount Santubong, Kuching Division, NW Sarawak, Malaysian Borneo. An identification key to all species is given and H. santubongensis is illustrated from living plants.
CONCLUSION: Haniffia santubongensis is the fourth species of Haniffia so far described, and the first occurring on sandstone.
Diversity of pollination ecology in the Schismatoglottis Calyptrata Complex Clade (Araceae)

Hoe YC, Gibernau M, Wong SY

Plant Biol (Stuttg), 2018 May;20(3):563-578.
PMID: 29316090 DOI: 10.1111/plb.12687

Field studies integrating pollination investigations with an assessment of floral scent composition and thermogenesis in tropical aroids are rather few. Thus, this study aimed to investigate the pollination biology of nine species belonging to Schismatoglottis Calyptrata Complex Clade. The flowering mechanism, visiting insect activities, reproductive system, thermogenesis and floral scent composition were examined. Anthesis for all species started at dawn and lasted 25-29 h. Colocasiomyia (Diptera, Drosophilidae) are considered the main pollinators for all the investigated species. Cycreon (Coleoptera, Hydrophilidae) are considered secondary pollinators as they are only present in seven of the nine host plants, despite the fact that they are the most effective pollen carrier, carrying up to 15 times more pollen grains than Colocasiomyia flies. However, the number of Colocasiomyia individuals was six times higher than Cycreon beetles. Chaloenus (Chrysomelidae, Galeuricinae) appeared to be an inadvertent pollinator. Atheta (Coleoptera, Staphylinidae) is considered a floral visitor in most investigated species of the Calyptrata Complex Clade in Sarawak, but a possible pollinator in S. muluensis. Chironomidae midges and pteromalid wasps are considered visitors in S. calyptrata. Thermogenesis in a biphasic pattern was observed in inflorescences of S. adducta, S. calyptrata, S. giamensis, S. pseudoniahensis and S. roh. The first peak occurred during pistillate anthesis; the second peak during staminate anthesis. Inflorescences of all investigated species of Calyptrata Complex Clade emitted four types of ester compound, with methyl ester-3-methyl-3-butenoic acid as a single major VOC (volatile organic compound). The appendix, pistillate zone, staminate zone and spathe emitted all these compounds. A mixed fly-beetle pollination system is considered an ancestral trait in the Calyptrata Complex Clade, persisting in Sarawak taxa, whereas the marked reduction of interpistillar staminodes in taxa from Peninsular Malaysia and especially, Ambon, Indonesia, is probably linked to a shift in these taxa to a fly-pollinated system.
Evaluation of electric vehicle response capability in power grid

Wong SY, Liang K, Goh HH

In recent years, frequent and substantial area-wide power outages have underscored the critical need for cities to possess robust backup power sources capable of swift response to prevent prolonged power system disruptions. Electric vehicles can contribute electricity to the power grid using vehicle-to-grid technology. The power delivered by electric vehicles in this context is termed as response capability. However, existing studies have overlooked response capability dynamics during transitions between electric vehicle states-such as the shift from charging or discharging to an idle state, thereby hindering a comprehensive understanding of this aspect. Hence, this paper introduces a multi-timescale response capability prediction model that evaluates the electric vehicle's state of charge to ensure users' requirements are met for upcoming trips. To better assess users' travel demand, the gravity model is employed as a precursor to response capability prediction to further enhance the validity of the prediction outcomes. Three neighborhoods in Los Angeles have been chosen for analysis: Downtown, Lincoln Heights, and Silver Lake. Predictions indicate that neglecting the response capability when electric vehicles undergo state transformation can lead to a differential response capability ranging from 2000 kWh to 4000 kWh, resulting in a loss of prediction accuracy by 20 % to 25 %.•The response capability of EV is non-zero during state transformations•Users' travel demand assessment•Seamless integration of vehicle-to-grid technology into the power grid.

Tan F, Liew SF, Chan G, Toh V, Wong SY

J Eval Clin Pract, 2011 Feb;17(1):40-4.
PMID: 20807297 DOI: 10.1111/j.1365-2753.2010.01367.x

RATIONALE, AIMS AND OBJECTIVES: To evaluate the impact of clinical audit on diabetes care provided to type 2 diabetic patients attending our hospital general medical clinics.
METHODS: Performances on diabetes-related process measures and intermediate outcome measures were evaluated through structured review of outpatient medical records. The results were fed back to the doctors and measures were implemented to improve care. The performance indicators were re-evaluated 2 years later to complete the audit cycle.
RESULTS: Annual testing rates improved for HbA1c (68.4% vs. 87.4%; P < 0.001) and lipid profile (91.8% vs. 97%; P = 0.027). Enquiry on smoking improved from 45.9% to 82.3% (P < 0.001), eye screening rates from 68.9% to 78.8% (P = 0.020) and foot examinations from 22.4% to 64.1% (P < 0.001). Prescription rates for insulin increased from 17.3% to 31.8% (P = 0.001) and statin from 83.2% to 94.4% (P < 0.001). The use of aspirin (80.6% vs. 83.8%; P =0.402) and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (92.3% vs. 88.9%; P = 0.239) remained high in both cycles. More patients achieved targets for HbA1c < 7% (38% vs. 26%; P = 0.006), blood pressure < 130/80 mmHg (43% vs. 32%; P = 0.071) and low-density lipoprotein cholesterol < 2.6 mmol/L (71% vs. 52%; P <0.001).
CONCLUSION: Clinical audit is a useful tool in improving diabetes care.

Fulltext Awareness, knowledge and attitudes towards epilepsy among rural populations in East Coast Peninsular Malaysia: a preliminary exploration

Neni SW, Latif AZ, Wong SY, Lua PL

Seizure, 2010 Jun;19(5):280-90.
PMID: 20466567 DOI: 10.1016/j.seizure.2010.04.006

This study was carried out to gauge the preliminary insight regarding epilepsy among the rural society. The purposes of this study were: (1) to determine general level of awareness, knowledge and attitudes (AKA) towards epilepsy among rural communities, (2) to compare the AKA level based on socio-demographic characteristics and (3) to investigate rural cohort's perception of the best epilepsy treatment, preference for epilepsy information delivery and preference for mode of transportation to seek medical treatment. This prospective, cross sectional study included a sample of 615 rural residents enrolled via cluster sampling in East Coast region of Peninsular Malaysia (mean age=41.6+/-18.02, female=56.6%, married=65.5%, Malay=94.0%, monthly income < or = RM 500=56.9%). The Total AKA level was generally low (2.66+/-0.7). Gender-wise no significant difference was shown regarding AKA level (p>0.05). However, respondents with higher education significantly possessed better attitudes and higher Total AKA level compared to those with lower education level (p<0.001). Employed respondents reported significantly more favourable attitudes than unemployed respondents (p=0.011). Additionally, higher income rural cohorts possessed both significantly better attitudes and better AKA. These rural communities perceived modern medicine as the best epilepsy treatment (56.60%), preferred to obtain direct epilepsy-related information from health personnel (60.4%) and chose to use their own car to seek medical treatment in hospital (76.30%). The outcomes of this preliminary study signified the need to devise a dedicated epilepsy education program for implementation among rural residents. Increased AKA level in the society could enhance the people's acceptance, reduce stigmatisation and improve health-related quality of life (HRQoL) for epilepsy patients and their family.
Flowering mechanisms, pollination strategies and floral scent analyses of syntopically co-flowering Homalomena spp. (Araceae) on Borneo

Hoe YC, Gibernau M, Maia AC, Wong SY

Plant Biol (Stuttg), 2016 Jul;18(4):563-76.
PMID: 26780890 DOI: 10.1111/plb.12431

In this study, the flowering mechanisms and pollination strategies of seven species of the highly diverse genus Homalomena (Araceae) were investigated in native populations of West Sarawak, Borneo. The floral scent compositions were also recorded for six of these species. The selected taxa belong to three out of four complexes of the section Cyrtocladon (Hanneae, Giamensis and Borneensis). The species belonging to the Hanneae complex exhibited longer anthesis (53-62 h) than those of the Giamensis and Borneensis complexes (ca. 30 h). Species belonging to the Hanneae complex underwent two floral scent emission events in consecutive days, during the pistillate and staminate phases of anthesis. In species belonging to the Giamensis and Borneensis complexes, floral scent emission was only evident to the human nose during the pistillate phase. A total of 33 volatile organic compounds (VOCs) were detected in floral scent analyses of species belonging to the Hanneae complex, whereas 26 VOCs were found in samples of those belonging to the Giamensis complex. The floral scent blends contained uncommon compounds in high concentration, which could ensure pollinator discrimination. Our observations indicate that scarab beetles (Parastasia gestroi and P. nigripennis; Scarabaeidae, Rutelinae) are the pollinators of the investigated species of Homalomena, with Chaloenus schawalleri (Chrysomelidae, Galeuricinae) acting as a secondary pollinator. The pollinators utilise the inflorescence for food, mating opportunities and safe mating arena as rewards. Flower-breeding flies (Colocasiomyia nigricauda and C. aff. heterodonta; Diptera, Drosophilidae) and terrestrial hydrophilid beetles (Cycreon sp.; Coleoptera, Hydrophilidae) were also frequently recovered from inflorescences belonging to all studied species (except H. velutipedunculata), but they probably do not act as efficient pollinators. Future studies should investigate the post-mating isolating barriers among syntopically co-flowering Homalomena sharing the same visiting insects.

Kurup A, Leo YS, Tan AL, Wong SY

Ann Acad Med Singap, 1999 Jul;28(4):605-9.
PMID: 10561784

Penicillium marneffei has emerged as an important opportunistic pathogen in HIV-infected patients in Southeast Asia. We report the first 5 cases of P. marneffei diagnosed in Singapore. All the patients were HIV-infected and were either Thai nationals or had frequently travelled to Thailand. Fever, weight loss, anaemia and papular skin lesions were common clinical manifestations in our patients, all of whom had the organism isolated from blood. Skin biopsy specimens showed histological evidence of P. marneffei in 2 patients. In 1 patient each, the organism grew in cultures of specimens from bone marrow and respiratory secretions. Amphotericin B therapy followed by itraconazole were used in 3 of our 5 patients and was associated with good clinical response and outcome.
Fulltext A Study on Arrhythmia via ECG Signal Classification Using the Convolutional Neural Network

Wu M, Lu Y, Yang W, Wong SY

Front Comput Neurosci, 2020;14:564015.
PMID: 33469423 DOI: 10.3389/fncom.2020.564015

Cardiovascular diseases (CVDs) are the leading cause of death today. The current identification method of the diseases is analyzing the Electrocardiogram (ECG), which is a medical monitoring technology recording cardiac activity. Unfortunately, looking for experts to analyze a large amount of ECG data consumes too many medical resources. Therefore, the method of identifying ECG characteristics based on machine learning has gradually become prevalent. However, there are some drawbacks to these typical methods, requiring manual feature recognition, complex models, and long training time. This paper proposes a robust and efficient 12-layer deep one-dimensional convolutional neural network on classifying the five micro-classes of heartbeat types in the MIT- BIH Arrhythmia database. The five types of heartbeat features are classified, and wavelet self-adaptive threshold denoising method is used in the experiments. Compared with BP neural network, random forest, and other CNN networks, the results show that the model proposed in this paper has better performance in accuracy, sensitivity, robustness, and anti-noise capability. Its accurate classification effectively saves medical resources, which has a positive effect on clinical practice.
Fulltext Playing Edcraft at Home: Gamified Online Learning for Recycling Intention during Lockdown

Cheng KM, Koo AC, Mohd Nasir JS, Wong SY

F1000Res, 2021;10:890.
PMID: 35035889 DOI: 10.12688/f1000research.72761.2

Background: Gamification is an innovative approach to engaging in activities that people believe as less interesting. Recycling has been an issue not taken aware by the people in environmental sustainability. There are substantial studies on recycling intention due to the continual growth of unethical and unsustainable waste disposal. Creative approaches to recycling awareness activities should be made to fulfil youths' increasing interest in and demand for recycling. The main objective of this study is to explore the factors related to youths' recycling intentions after experiencing a gamified online recycling learning activity, Edcraft Gamified Learning (EGL). Gamified recycling education is believed to be a practical and engaging approach for youths. Methods: 100 students participated in EGL, consisting of two levels of plastic crafting and recycling activities. They experienced online EGL at home between May and September in 2020, during the COVID-19 pandemic total lockdown in Malaysia, namely, Movement Control Order (MCO). 29 participants were selected to participate in five focus group discussions (FGDs) with five to eight participants per session to explore their opinions towards gamified learning, motivation and recycling intention. Results: This paper reports the findings of the FGDs. A codebook was developed based on the codes from the FGD feedback. The codes were rated by two raters, followed by an assessment of inter-rater reliability and thematic analysis. The findings emerged and were confirmed with four themes as factors that influence recycling intention. They are gameful experience, social influence, intrinsic motivation, and extrinsic motivation. Conclusion: The dependent variable, recycling intention, was connected to the four themes to verify the conceptual framework. One limitation of the study was the design of the EGL activity, which was only carried out over two days with two levels of gamified recycling education, as students had concurrent academic online classes during that period.
Schismatoglottis and Apoballis (Araceae: Schismatoglottideae): A new example for the significance of pollen morphology in Araceae systematics

Ulrich S, Hesse M, Bröderbauer D, Wong SY, Boyce PC

Taxon, 2012 Apr 13;61(2):281-292.
PMID: 28904408

Pollen characters in Araceae accord well with recent DNA-based phylogenies, and here we provide a new example of "compass needle" quality in Araceae on the basis of two closely related genera, Schismatoglottis and Apoballis. All investigated Schismatoglottis pollen is psilate (smooth pollen surface) with calcium crystals covering the pollen surface. By contrast, pollen of species transferred to recently resurrected Apoballis (Apoballis acuminatissima and A. mutata) is distinctively echinate (spiny). A unique layer covers the endexine of Schismatoglottis, and the whole pollen surface of Apoballis. Our findings strongly suggest that "Schismatoglottis" species with echinate pollen fall into the genus Apoballis. Moreover, all schismatoglottid taxa perform spathe movements during anthesis to control the movement of pollinators. The spathe movements of Apoballis acuminatissima clearly differ from those known in Schismatoglottis species, and indeed are so far unique for the entire family. This, together with differences in floral odour is strongly suggestive of differences in pollination ecology between the genera Schismatoglottis and Apoballis.

Fulltext An evaluation of online Edcraft gamified learning (EGL) to understand motivation and intention of recycling among youth

Recycling is a process carried out by various organizations and individuals to enhance the environment's long-term sustainability. Some youth think that recycling is a monotonous action as it may seem inconvenient, less aware of the environmental issues and more time-consuming than they think and rather go for video games. Therefore, this study investigates the relationship between motivation and recycling intention in gamified learning among youth. To address the research aim, this study uses gamification as a motivational driver for a game-like learning experience to improve recycling intentions among youth. Self-determination theory (SDT) and the theory of Planned Behavior (TPB) will be this study's main motivational and behavioral theories. (n = 124) high schools and college students were invited to take part in an online gamified recycling activity, Edcraft Gamified Learning (EGL), consisting of two levels of gamified unused plastic-crafting recycling activities. After the activity, the participants will answer a post-event questionnaire and the data collected were analyzed. The result shows that controlled motivation (CM) and autonomous motivation (AM) positively influenced youth attitudes and social norms. Besides, attitude is the only psychosocial determinant that positively influences the recycling intention of the youth. Gamification only moderates positively between attitude and recycling intention. This study has clearly shown the effectiveness of gamified learning activity towards recycling intention directly and as a component that moderates the relationship between attitude and recycling intention, which shows a favorable evaluation towards recycling intention with gamified learning involved. Moreover, the findings showed that not all relationships are positive in a gamified learning environment, and it gives a good view on the weakness and strengths with the guideline of SDT and TPB.
Floral diversity and pollination strategies of three rheophytic Schismatoglottideae (Araceae)

Low SL, Wong SY, Ooi IH, Hesse M, Städler Y, Schönenberger J, et al.

Plant Biol (Stuttg), 2016 Jan;18(1):84-97.
PMID: 25688576 DOI: 10.1111/plb.12320

Homoplastic evolution of 'unique' morphological characteristics in the Schismatoglottideae - many previously used to define genera - prompted this study to compare morphology and function in connection with pollination biology for Aridarum nicolsonii, Phymatarum borneense and Schottarum sarikeense. Aridarum nicolsonii and P. borneense extrude pollen through a pair of horned thecae while S. sarikeense sheds pollen through a pair of pores on the thecae. Floral traits of spathe constriction, presence and movement of sterile structures on the spadix, the comparable role of horned thecae and thecae pores, the presence of stamen-associated calcium oxalate packages, and the timing of odour emission are discussed in the context of their roles in pollinator management. Pollinators for all investigated species were determined to be species of Colocasiomyia (Diptera: Drosophilidae).
Fulltext Sleep position and infant care practices in an urban community in Kuala Lumpur

Lope RJ, Kong WK, Lee VW, Tiew WT, Wong SY

Med J Malaysia, 2010 Mar;65(1):45-8.
PMID: 21265248 MyJurnal

Several modifiable risk factors for sudden infant death syndrome (SIDS) have been identified such as sleeping prone or on the side, sleeping on a soft surface, bed-sharing, no prenatal care and maternal ante-natal smoking. A cross-sectional survey of infant sleep and care practices was conducted among parents of babies aged below 8 months to determine the prevalence and predictors of non-supine sleep position and the prevalence of other high-risk infant care practices for SIDS. Of 263 infants, 24.7% were placed to sleep in the non-supine position and age of infants was a factor positively associated with this (adjusted odds ratio 1.275, 95% CI=1.085, 1.499). The most common modifiable risk factor was the presence of soft toys or bedding in the infants' bed or cot (89.4%). Results from this study indicate that although the predominant sleep position of Malaysian infants in this population is supine, the majority of infants were exposed to other care practices which have been shown to be associated with SIDS.
