Husain AR, Hadad Y, Zainal Alam MN

J Lab Autom, 2016 Oct;21(5):660-70.
PMID: 26185253 DOI: 10.1177/2211068215594770

This article presents the development of a low-cost microcontroller-based interface for a microbioreactor operation. An Arduino MEGA 2560 board with 54 digital input/outputs, including 15 pulse-width-modulation outputs, has been chosen to perform the acquisition and control of the microbioreactor. The microbioreactor (volume = 800 µL) was made of poly(dimethylsiloxane) and poly(methylmethacrylate) polymers. The reactor was built to be equipped with sensors and actuators for the control of reactor temperature and the mixing speed. The article discusses the circuit of the microcontroller-based platform, describes the signal conditioning steps, and evaluates the capacity of the proposed low-cost microcontroller-based interface in terms of control accuracy and system responses. It is demonstrated that the proposed microcontroller-based platform is able to operate parallel microbioreactor operation with satisfactory performances. Control accuracy at a deviation less than 5% of the set-point values and responses in the range of few seconds have been recorded.

Yan Z, Mansor ZD, Choo WC, Abdullah AR

Psychol Res Behav Manag, 2021;14:185-197.
PMID: 33633474 DOI: 10.2147/PRBM.S293839

Background: The hospitality industry is deemed a great generator of global GDP and employment. However, high rates of voluntary turnover have gradually undermined global service organizations and brought huge losses to them. Nowadays, the hotel sector continues to be plagued by high turnover rates.
Purpose: A research model investigating job attitudes (job satisfaction and organizational commitment) as mediators of the impact of psychological capital (PsyCap) on turnover intention and also examining position as a moderator between job attitudes and turnover intention was proposed and tested.
Methods: This study collected data from 406 employees selected from four-star and five-star hotels in the southwest region of China. Online survey questionnaires and a purposive sampling technique were employed in this study. Structural equation modeling was utilized to evaluate the direct, mediating, and moderating effects.
Results: The results showed that organizational commitment and job satisfaction fully mediated the association between PsyCap and turnover intention. Moreover, position played a moderating role on the effect of the aforementioned two job attitudes on turnover intention.
Conclusion: The findings implied that hoteliers should focus on employees' PsyCap and job attitudes in order to mitigate serious turnover issues in the hotel sector in China. Besides, the fact that position resulted in disparity impacts in the formation of turnover intention was evidenced.
Fulltext The influence of angiotensin I-converting enzyme (ACE) I/D gene polymorphism on cardiovascular and muscular adaptations following 8 weeks of isometric handgrip training (IHG) in untrained normotensive males

Yusof HA, Aziz AR, Muhamed AMC

Biol Sport, 2019 Mar;36(1):81-94.
PMID: 30899143 DOI: 10.5114/biolsport.2019.79975

We examined the association between the angiotensin I-converting enzyme (ACE) I/D gene polymorphism and isometric handgrip (IHG) training on cardiovascular and muscular responses among normotensive males. Thirty (II = 10, ID = 10, and DD = 10) normotensive untrained males underwent IHG training at 30% of their maximal voluntary contraction 3 days per week for 8 weeks. Cardiovascular and muscular variables were measured before IHG, after a session of IHG and after 8 weeks of IHG. No significant interaction effect was found between ACE I/D genotype and IHG training session on all dependent variables (all p > 0.05). There was a significant main effect of IHG training session on systolic blood pressure (SBP) (p = 0.002), mean arterial pressure (MAP) (p = 0.015) and handgrip strength (HGS) (p = 0.001) scores, while no difference in diastolic blood pressure (DBP), pulse pressure, or heart rate scores was found. A greater improvement in cardiovascular parameters following 8 weeks of IHG training was observed in participants with the D allele than the I allele (SBP reduction: ID+DD genotype group (-5.53 ± 6.2 mmHg) vs. II genotype group (-1.52 ± 5.3 mmHg)); MAP reduction: ID + DD genotype group (-2.80 ± 4.5 mmHg) vs. II genotype group (-1.45 ± 3.5 mmHg). Eight weeks of IHG training improved cardiovascular and muscular performances of normotensive men. Reduction in SBP and MAP scores in D allele carriers compared to I allele carriers indicates that the ACE I/D polymorphism may have an influence on IHG training adaptation in a normotensive population.

PMID: 35126503 DOI: 10.1155/2022/8235308

Gross domestic product (GDP) is an important indicator for determining a country's or region's economic status and development level, and it is closely linked to inflation, unemployment, and economic growth rates. These basic indicators can comprehensively and effectively reflect a country's or region's future economic development. The center of radial basis function neural network and smoothing factor to take a uniform distribution of the random radial basis function artificial neural network will be the focus of this study. This stochastic learning method is a useful addition to the existing methods for determining the center and smoothing factors of radial basis function neural networks, and it can also help the network more efficiently train. GDP forecasting is aided by the genetic algorithm radial basis neural network, which allows the government to make timely and effective macrocontrol plans based on the forecast trend of GDP in the region. This study uses the genetic algorithm radial basis, neural network model, to make judgments on the relationships contained in this sequence and compare and analyze the prediction effect and generalization ability of the model to verify the applicability of the genetic algorithm radial basis, neural network model, based on the modeling of historical data, which may contain linear and nonlinear relationships by itself, so this study uses the genetic algorithm radial basis, neural network model, to make, compare, and analyze judgments on the relationships contained in this sequence.

Adam IK, Heikal M, Aziz ARA, Yusup S

Environ Sci Pollut Res Int, 2018 Oct;25(28):28500-28516.
PMID: 30088249 DOI: 10.1007/s11356-018-2863-8

The present work analyzes the effect of antioxidants on engine combustion performance of a multi-cylinder diesel engine fueled with PB30 and PB50 (30 and 50 vol.% palm biodiesel (PB)). Four antioxidants namely N,N'-diphenyl-1,4-phenylenediamine (DPPD), N-phenyl-1,4-phenylenediamine (NPPD), 2(3)-tert-Butyl-4-methoxyphenol (BHA), and 2-tert-butylbenzene-1,4-diol (TBHQ) were added at concentrations of 1000 and 2000 ppm to PB30 and PB50. TBHQ showed the highest activity in increasing oxidation stability in both PB30 and PB50 followed by BHA, DPPD, and NPPD respectively, without any negative effect on physical properties. Compared to diesel fuel, PB blends showed 4.61-6.45% lower brake power (BP), 5.90-8.69% higher brake specific fuel consumption (BSFC), 9.64-11.43% higher maximum in cylinder pressure, and 7.76-12.51% higher NO emissions. Carbon monoxide (CO), hydrocarbon (HC), and smoke opacity were reduced by 36.78-43.56%, 44.12-58.21%, and 42.59-63.94%, respectively, than diesel fuel. The start of combustion angles (SOC) of PB blends was - 13.2 to - 15.6 °CA BTDC, but the combustion delays were 5.4-7.8 °CA short compared to diesel fuel which were - 10 °CA BTDC and 11°CA respectively. Antioxidant fuels of PB showed higher BP (1.81-5.32%), CO (8.41-24.60%), and HC (13.51-37.35%) with lower BSFC (1.67-7.68%), NO (4.32-11.53%), maximum in cylinder pressure (2.33-4.91%) and peak heat release rates (HRR) (3.25-11.41%) than baseline fuel of PB. Similar SOC of - 13 to - 14 °CA BTDC was observed for PB blended fuels and antioxidants. It can be concluded that antioxidants' addition is effective in increasing the oxidation stability and in controlling the NOx emissions of palm biodiesel fuelled diesel engine.
Fulltext Methadone Maintenance Treatment for Opioid Dependents: a Retrospective Study

Khalid K, Ooi YT, Abdul Rashid Q, Mohammad Yusoff MZA, Jamaluddin R

East Asian Arch Psychiatry, 2022 Sep;32(3):47-50.
PMID: 36172721 DOI: 10.12809/eaap2214

OBJECTIVES: To determine the prevalence of continued illicit drug use among people enrolled in methadone maintenance treatment (MMT), the association between hepatitis C status and methadone dosage, and the predictors for illicit drug abstinence during MMT.
METHODS: Clinical records of active opioid dependents who underwent MMT between 1 January 2007 and 31 March 2021 in Hospital Tuanku Fauziah, Perlis, Malaysia were retrospectively reviewed. Data collected included baseline demographics, history of illicit drug use, temporal trend in methadone dosage modulation, and co-use of illicit drugs during the MMT.
RESULTS: A total of 87 patients (mean age, 43.9 ± 8.33 years) were included. Their mean duration of involvement in MMT was 7.8 ± 3.69 years. The most commonly used drug was heroin (88.5%), followed by kratom (51.7%). Between 2019 and 2021, 61 (70.1%) patients had ceased abusing opioid, but 51 (58.6%) patients continued using any of the illicit drugs. Methamphetamine and amphetamine co-use was most common (n = 12, 37.5%). Hepatitis C status was not associated with the current methadone dose (U = 539.5, p = 0.186) or the highest dose required (t = -0.291, df = 74, p = 0.772). No predictor for illicit drug abstinence during MMT was identified. Methadone dose positively correlated with frequency of defaulting treatments (r = 0.22, p = 0.042).
CONCLUSION: Among our patients, MMT for opioid dependents cannot sufficiently curb illicit drug use, and there is a shift toward stimulants abuse.
Fulltext International Trade Path with Multi-Polarization based on Multidirectional Mutation Genetic Algorithm Enabled Neural Network

Zhang Q, Chong CW, Abdullah AR, Ali MH

Comput Intell Neurosci, 2021;2021:1370180.
PMID: 34691167 DOI: 10.1155/2021/1370180

At present, the development speed of international trade cannot catch up with the economic development speed, and the insufficient development speed of international trade will directly affect the rapid development of national economy. In order to solve the problem of international trade, the overall optimal scheduling of trade vehicles and the optimal planning of trade transportation path are very important to improve enterprise services, reduce enterprise costs, increase enterprise benefits, and enhance enterprise competitiveness. The second development of the program is based on the programming interface provided by Baidu map. This paper proposes a neural network algorithm for genetic optimization of multiple mutations, which overcomes the shortcoming of traditional genetic algorithm population "ten" character distribution by mixing multiple coding methods, and enhances the local search ability of genetic algorithm by introducing a new large-mutation small-range search population. The example application shows that the optimization method can realize the optimization of international trade path under real road conditions and greatly improve the work efficiency of actual trade.

This article was migrated. The article was marked as recommended. Millennials are the most prevalent generation of medical learners today. These individuals have a unique outlook on education and have different preferences and expectations than their predecessors. The majority of our learners belong to the Millennial Generation, while most faculty belongs to the Baby Boomer or Generation X cohorts. Millennial learners have distinct perspectives on their learning needs that differ with their faculty's perspectives on teaching and learning. These learning differences may contribute to intergenerational conflict. In order to be successful teachers, it is important to educate ourselves on these generational differences and cater to the needs of the learners. Heutagogy is a self-determined approach of learning, which appears to suit the millennial learners. Derived from the word " Heureskein" which means to discover, the term heutagogy was coined to describe self-learning, independent of formal teaching. This adds yet another learning theory to the established fields of pedagogy (child learning) and andragogy (adult learning). Heutagogy acknowledges that learner do immensely valuable work for themselves by filling in the gaps of their formal education through discovery and reflection. Heutagogy offers models of learning that are (1) self-determined, (2) peer-led, and (3) non-linear. These characteristics map onto social media applications and the democratization of knowledge and information. Heutagogical approach is an extension of the traditional andragogical and adult learning frameworks through its emphasis on meta learning, or learning how to learn. This article presents the paradigm shift of educational strategies from pedagogy to andragogy to heutagogy and focuses on the ground principles governing heutagogy. It also describes an innovative case study where principles of heutagogy were applied to train dental students using Facebook.

Roney M, Issahaku AR, Aluwi MFFM

In Silico Pharmacol, 2023;11(1):36.
PMID: 37994367 DOI: 10.1007/s40203-023-00176-y

The finest sources of therapeutic agents are natural products, and usnic acid is a secondary metabolite derived from lichen that has a wide range of biological actions, including anti-viral, anti-cancer, anti-bacterial, and anti-diabetic (hyperglycemia). Based on the hyperglycemia activity of UA, this work seeks to identify new anti-hyperglycemia medicines by virtual screening of pyrazole derivatives of UA. Seven hit compounds (Compounds 1, 5, 6, 7, 17, 18 and 33), which finally go through docking-based screening to produce the lead molecule, were identified by the physicochemical attributes, drug-likeliness, and ADMET prediction. The docking score for the chosen compounds containing PPARγ agonists ranged from -7.6 to -9.2 kcal/mol, whereas the docking goal for compounds 5, 6, and 7 was -9.2 kcal/mol. Based on the binding energy and bound amino acid residues as well as compared to the reference compound, compound-6 considered as lead compound. Furthermore, the MD simulation of 3CS8-Compound-6 and 3CS8-Rosiglitazone complexes were performed to verify the stability of these complexes and the binding posture acquired in docking experiments. The compound-6 had strong pharmacological characteristics, bound to the PPARγ agonist active site, and was expected to reduce the activity of the receptor, according to the virtual screening results. It must be justified to conduct both in-vitro and in-vivo experiments to examine the efficacy of this compound.

PMID: 39499905 DOI: 10.1139/apnm-2024-0219

Relative to exercise in a thermoneutral environment, there is only limited evidence demonstrating that a low glycaemic index (LGI) pre-exercise meal can enhance endurance exercise performance in a hot-humid (HH) condition. Also, previous studies predominantly utilised Western-based and single food items, with minimal focus on Asian-based mixed meals. This study aimed to investigate the impact of pre-exercise LGI and high glycaemic index (HGI) rice-based mixed meals on endurance performance among acclimatised trained athletes in HH condition (32 °C, 65% relative humidity). Twelve native-born endurance-trained male runners (age 22.0 ± 5.8 years; peak oxygen consumption (V̇O2peak) 64.2 ± 5.5 mL kg-1 min-1) completed two trials consisting of 45 min steady-state (SS) run at 70% V̇O2peak followed by 10 km performance run (TT10km). Three hours before exercise, participants consumed an isocaloric rice-based mixed meals containing either LGI (GI value = 47) or HGI (GI value = 80), providing 1.3 g of carbohydrate (CHO) per kg of body mass. Participants ran faster during TT10 km after consuming the LGI meal compared to the HGI meal (LGI: 55.18 ± 1.22 vs. HGI: 57.03 ± 2.25 min, p = 0.010). End rectal temperature did not significantly differ between trials (LGI: 39.16 ± 0.74 vs. HGI: 38.95 ± 0.46 °C, p = 0.352). Fat oxidation was higher during the SS run in the LGI compared to the HGI trial (LGI: 0.19 ± 0.05 vs. HGI: 0.13 ± 0.19 g min-1, p = 0.001). This study demonstrated that, relative to HGI, consuming a pre-exercise LGI rice-based mixed meal enhanced endurance performance in HH environment among acclimatised trained male athletes.

Abd Karim NB, Ismail NM, Naing L, Ismail AR

Malays J Med Sci, 2008 Oct;15(4):35-40.
PMID: 22589636

Tooth wear is the non-carious loss of tooth tissue, which results from three processes namely attrition, erosion and abrasion. These can occur in isolation or simultaneously. Very mild tooth wear is a physiological effect of aging. This study aims to estimate the prevalence of tooth wear among 16-year old Malay school children and determine a feasible sample size for further study. Fifty-five subjects were examined clinically, followed by the completion of self-administered questionnaires. Questionnaires consisted of socio-demographic and associated variables for tooth wear obtained from the literature. The Smith and Knight tooth wear index was used to chart tooth wear. Other oral findings were recorded using the WHO criteria. A software programme was used to determine pathological tooth wear. About equal ratio of male to female were involved. It was found that 18.2% of subjects have no tooth wear, 63.6% had very mild tooth wear, 10.9% mild tooth wear, 5.5% moderate tooth wear and 1.8 % severe tooth wear. In conclusion 18.2% of subjects were deemed to have pathological tooth wear (mild, moderate & severe). Exploration with all associated variables gave a sample size ranging from 560 - 1715. The final sample size for further study greatly depends on available time and resources.

PMID: 22589623

Involvement of oral health educators among non-health professionals in oral health promotion is important in the prevention of oral diseases. This study was carried out to compare the level of oral health knowledge among pre-school teachers before and after oral health seminar. Pre-test data was collected by distributing questionnaire to pre-school teachers in Pasir Mas, who attended the seminar on "Oral Health" (n=33) and they were required to fill anonymously before the seminar started. The questions consisted of information on general background, perceived oral health status, oral health knowledge and the environment where they work. After two weeks, post-test data was collected using the same structured questionnaire and identification code was used to match the pre and post data. SPSS 11.5 was use for statistical analysis. Two out of 33 eligible preschool teachers were considered non-respondents due to absenteeism during the post-test data collection. The response rate was 94.0% (n = 31). The study shows a significant improvement in oral health knowledge among pre-school teachers in Pasir Mas, after seminar (p < 0.001) as compared to controls. Thus, we can conclude that the oral health programme (seminar) appeared effective at influencing oral health educator's knowledge towards oral health.

Introduction: Since 1978, Rohingya refugees have fled from their native nation, Myanmar to escape ethnic prose- cution. They comprise of the Muslim minority ethnic group originating from the Rakhine state in Myanmar. In many host countries, they may have difficulty to access health care services. The Islamic Association of Malaysia (IMAM) Response and Relief Team (IMARET) have taken many initiatives to provide healthcare services to the refugees through their volunteer-led mobile clinics. Therefore, this study aims to evaluate the utilisation of drugs among type 2 diabetes mellitus (T2DM) patients visiting this clinic. Methods: This was a cross-sectional study among Rohingya refugees with T2DM that visited the IMARET mobile clinics from August until November 2017. Convenient sampling method was used. Data were collected through patient’s interview, review of the patient’s prescriptions and their HbA1c readings. Results: A total of 29 T2DM patients were included in this study. The majority were female (75.9%) and aged below 65 years old (75.9%). The most commonly prescribed anti-diabetic agent was metformin (72.2%), followed by glibenclamide (22.2%) and gliclazide (5.6%). Metformin as a monotherapy (31%) was the most frequent treatment prescribed. More patients had controlled T2DM (62.1%) compared to those with uncontrolled DM. We found 90.9% of patients who were treated according to the recommended DM guidelines achieved a good blood glucose control (p=0.02). Conclusion: In Rohingya refugees having T2DM who were treated in the IMARET mobile clinic, the percentage having good control DM status is higher in those whose treatment regimen adheres to the clinical practice guidelines.

This is a cross-sectional study in a representative sample of preschool children from 12 preschools (TADIKA KEMAS) Pasir Mas, Kelantan, Malaysia. Data on socioeconomic status and sources of water supply at home were collected through interview with mothers. Children’s anthropometric data (height and weight) and body-mass-index-for-age (BMI-for-age) was calculated. Oral examinations of ECC status was based on the dmft index (WHO, 1997). The results showed mean
carious teeth were very high (dmft 11.1±4.8) and almost every preschool child was affected with ECC (prevalence 98.1%). The majority were in “high caries” category (i.e. dmft >7) and about 51.4% of preschoolers was underweight and only a few was overweight/obese. Preschool children with high caries mostly were underweight and normal of BMI. The BMI-for-age, household income and household expenditure for food were significant correlation with ECC experience (p

The aim of this study was to determine the genotoxicity of a locally produced nanocomposite by Universiti Sains Malaysia, Malaysia using Comet assay. Stem cells from human exfoliated deciduous teeth (SHED) were treated with the nanocomposite at five different concentrations (0.006, 0.0125, 0.025, 0.05, and 0.1 mg/ml) along with concurrent negative (medium alone) and positive control (zinc sulfate heptahydrate) and incubated at 37°C for 24 hours in an incubator at 5% CO2. The tail moment was used to assess the extent of DNA damage. The tail moment for the group of SHED treated with nanocomposite (for all the five different concentrations) was not statistically significant as compared to the negative control, suggesting that the locally produced dental nanocomposite did not induce any DNA damage. Hence, it can be concluded that the locally produced nanocomposite is non-genotoxic on stem cells from human exfoliated deciduous teeth.

Introduction: Degenerative disorder involving the acromioclavicular
joint (ACJ) is quite common especially in the elderly.
One of the surgical modalities of treatment of this disorder is the
Mumford Procedure. Arthroscopic approach is preferred due to
its reduced morbidity and faster post-operative recovery. One
method utilizes the anteromedial and Neviaser portals, which
allow direct and better visualization of the ACJ from the
subacromial space. However, the dangers that may arise from
incision and insertion of instruments through these portals are
not fully understood. This cadaveric study was carried out to
investigate the dangers that can arise from utilization of these
portals and which structures are at risk during this procedure.
Methods: Arthroscopic Mumford procedures were performed
on 5 cadaver shoulders by a single surgeon utilizing the
anteromedial and Neviaser portals. After marking each portals
with methylene blue, dissection of nearby structures were
carried out immediately after each procedure was completed.
Important structures (subclavian artery as well as brachial plexus
and its branches) were identified and the nearest measurements
were made from each portal edges to these structures. Results:
The anteromedial portal was noted to be closest to the
suprascapular nerve (SSN) at 2.91 cm, while the Neviaser portal
was noted to be closest also to the SSN at 1.60 cm. The
suprascapular nerve was the structure most at risk during the
Mumford procedure. The anteromedial portal was noted to be
the most risky portal to utilize compared to the Neviaser portal.
Conclusion: Extra precaution needs to be given to the
anteromedial portal while performing an arthroscopic distal
clavicle resection in view of the risk of injuring the
suprascapular nerve of the affected limb.

Introduction: In first six months of life, breastfeeding is the recommended form of feeding by the World Health Organisation for the growing child. To enable the working mother to continue this noble practice, adequate workplace breastfeeding support and self- efficacy is needed. This study aims to determine the prevalence of breastfeeding among working mothers of children aged three months to two years and factors associated with breastfeeding practice including workplace support and mother’s self-efficacy. Method: This is a cross sectional questionnaire study carried out in a rural Health Clinic in Selangor using socio-demographic data, Workplace Breastfeeding Support Scale (WBSS), and the Breastfeeding Self-Efficacy Scale Short Form (BSES-SF). This study was conducted for a period of three months from April to June 2015. The respondents were employed Malaysian mothers of healthy infants aged three months to two years. A total of 84 participants were involved in the study. Data analysis was done with SPSS 22.Results: The prevalence of breastfeeding among working mothers were high at 97.6%. We found significant association of breastfeeding practice with workplace breastfeeding support (p=0.005) and self-efficacy (p= 0.017). We also noted a significant correlation between breastfeeding workplace support and breast feeding self-efficacy (r= 0.40, p
