Mohamad HA, Suzana S, Noor Ibrahim MS, Norshafarina S

Malays J Nutr, 2010 Dec;16(3):339-48.
PMID: 22691987 MyJurnal

Loss of appetite, decrease in food intake and changes in body composition appear to be inter-related factors that can influence the well-being of older individuals. Therefore, a study was conducted to determine the level of appetite, food intake and its relation to body composition and functional status among noninstitutionalised elderly Malays in Cheras, Kuala Lumpur. The Council on Nutrition Appetite Questionnaire (CNAQ), Diet History Questionnaire (DHQ), Bio-impedance Analysis (BIA) and Instrumental Activity of Daily Living (IADL) questionnaire and handgrip dynamometer were used to measure appetite, food intake, body composition and functional status respectively. A total of 112 subjects (41.1% men and 58.9% women) participated with mean age being 66.0 ± 5.0 years for men and 66.3 ± 6.2 years for women. Prevalence of poor appetite was higher in elderly women (72.3%) than in men (52.3%) (p<0.05). Pearson's correlation test showed that CNAQ score correlated significantly with age (r=-0.255, p<0.01), energy intake (r=0.272, p<0.01), IADL score (r=0.408, p<0.01) and handgrip strength (r=0.263, p<0.05). Energy intake correlated significantly with fat free mass (r=0.424, p<0.05), muscle mass (r=0.456, p<0.05) and total body water (r=0.403, p<0.05). Multiple regression analysis showed that 27.0% of poor appetite could be explained by advanced age, low energy intake and decreased functional status. In conclusion, the study showed that poor appetite was prevalent among the subjects, especially women and this was influenced by aging, inadequate energy intake and decreased functional status.

PMID: 17041549 MyJurnal

Amoebiasis is an infectious diseased caused by parasitic one-celled protozoan called Entamoeba histolytica. Numerous protozoa also can inhabit the gastro-intestinal tract of human. Majority of these protozoa are non-pathogenic commensals or only causes disease under certain circumstances. Morphologically, E. histolytica, the invasive form, share the same characteristic with the nonpathogenic form, E. dispar. Both strains can be distinguished by using DNA identification. Many previous researches in Malaysia only reported infection with E. histolytica infection. Therefore in this study we tried to classify infection among the aborigines in Cameron Highland as true E. histolytica or E. dispar by Nested Polymerase Chain Reaction (Nested PCR) and Restriction enzyme (RE) digestion. Results showed that 31 samples were positive by microscopic examination, however of these 28 (13.2%) samples were positive for E. histolytica and 12 (5.6%) samples were positive for E. dispar by molecular tools.

Julianto T, Yuen KH, Noor AM

J Chromatogr B Biomed Sci Appl, 1999 Sep 10;732(1):227-31.
PMID: 10517240

A simple high-performance liquid chromatographic method using UV detection was developed for the determination of alpha-tocopherol in human plasma. The method entailed direct injection of the plasma sample after deproteinization using acetonitrile-tetrahydrofuran (3:2). The mobile phase comprised methanol-tetrahydrofuran (94:6) and analysis was run at a flow-rate of 1.5 ml/min with the detector operating at 292 nm. A Crestpak C18S (5 microm, 250 mm x 4.6 mm ID) was used for the chromatographic separation. The method had a mean recovery of 93%, while the within-day and between-day coefficients of variation and percentage errors were all less than 7%. The speed, specificity, sensitivity and reproducibility of this method make it particularly suitable for routine determination of alpha-tocopherol in human plasma. Moreover, only a small sample plasma volume (100 microl) is required for the analysis.

Julianto T, Yuen KH, Noor AM

Int J Pharm, 2000 Apr 25;200(1):53-7.
PMID: 10845685

A single dose study was conducted to evaluate the bioavailability of a novel self-emulsifying vitamin E preparation, in comparison with that of a commercial product, Natopherol, available as soft gelatin capsules under fasted condition. The self-emulsifying preparation achieved a faster rate and higher extent of absorption. A statistically significant difference was observed between the values of the two preparations in the parameters AUC, Cmax and Tmax. Moreover, the 90% confidence interval of the logarithmic transformed AUC values of the self-emulsifying preparation over those of the soft gelatin capsule product was found to be between 2.1 and 4.1, suggesting an increase in bioavailability of between 210 and 410%. As for Cmax, the 90% confidence interval was between 2.1 and 3.0. However, no statistically significant difference was observed between the t(1/2) values estimated from the plasma concentration versus time data of the two preparations. The values are also comparable to those reported in the literature.

Jamaluddin ND, Mohd Noor N, Goh HH

Physiol Mol Biol Plants, 2017 Apr;23(2):357-368.
PMID: 28461724 DOI: 10.1007/s12298-017-0429-8

Genome-wide transcriptome profiling is a powerful tool to study global gene expression patterns in plant development. We report the first transcriptome profile analysis of papaya embryogenic callus to improve our understanding on genes associated with somatic embryogenesis. By using 3' mRNA-sequencing, we generated 6,190,687 processed reads and 47.0% were aligned to papaya genome reference, in which 21,170 (75.4%) of 27,082 annotated genes were found to be expressed but only 41% was expressed at functionally high levels. The top 10% of genes with high transcript abundance were significantly enriched in biological processes related to cell proliferation, stress response, and metabolism. Genes functioning in somatic embryogenesis such as SERK and LEA, hormone-related genes, stress-related genes, and genes involved in secondary metabolite biosynthesis pathways were highly expressed. Transcription factors such as NAC, WRKY, MYB, WUSCHEL, Agamous-like MADS-box protein and bHLH important in somatic embryos of other plants species were found to be expressed in papaya embryogenic callus. Abundant expression of enolase and ADH is consistent with proteome study of papaya somatic embryo. Our study highlights that some genes related to secondary metabolite biosynthesis, especially phenylpropanoid biosynthesis, were highly expressed in papaya embryogenic callus, which might have implication for cell factory applications. The discovery of all genes expressed in papaya embryogenic callus provides an important information into early biological processes during the induction of embryogenesis and useful for future research in other plant species.

Noor Khairiah AK, Mohamad Nazrulhisham MN, John G

Med J Malaysia, 2018 04;73(2):116-118.
PMID: 29703878 MyJurnal

Primary osteosarcoma of the spine is indeed rare and only several sporadic cases have been reported. It tends to occur in a slightly older age group than those with appendicular skeleton tumours. We present here an unusual case of aggressive lumbosacral osteosarcoma in a young teenager complicated by extensive dural spread, skip lesions and intravascular extension. Although a histopathological examination is mandatory to establish the diagnosis, this case emphasises the need of imaging to ascertain the full extent of disease spread especially in deciding the type of treatment to be instituted and to evaluate the response to the treatment.

Papaya is considered to be one of the most nutritional fruits. It is rich in vitamins, carotenoids, flavonoids and other phytonutrient which function as antioxidant in our body [1]. Previous studies revealed that the suppression of a negative regulator gene in photomorphogenesis, De-etiolated 1 (DET1) can improve the phytonutrient in tomato and canola without affecting the fruit quality [2], [3]. This report contains the experimental data on high-throughput 3' mRNA sequencing of transformed papaya callus upon DET1 gene suppression.

PMID: 27863606 DOI: 10.1016/j.ctcp.2016.09.005

OBJECTIVE: To evaluate the prevalence of use of complementary and alternative medicine (CAM) in a Malaysian antenatal population and its impact on obstetric outcome.

DESIGN: Cross sectional study.

SETTING: Obstetric Unit, Hospital Sultanah Bahiyah, Alor Setar, Kedah.

MATERIAL AND METHOD: Women attending antenatal clinic and Patient Admission Centre (PAC) above 30 weeks gestation were given structured questionnaires to fill. Pregnancy outcome measures were documented and analyzed in relation to the information gathered through the questionnaire. SPSS Version 21 was used to analyze all data obtained.

RESULTS: Out of 447 women, the overall prevalence of CAM usage in pregnancy was 85.2%. It was popular among pregnant mothers aged between 26 and 35 years old and most commonly used in the third trimester (p = 0.0.010) to facilitate labour. Other sociodemographic factors such as race, parity, education, occupation and residence were not significantly important. Traditional herbs was the commonest type of CAM used in pregnancy (58.3%) followed by selusuh (24.3%). About 78.5% of the CAM users delivered vaginally (p = 0.020) but a significant proportion (14.3%) had fetal distress (p = 0.035) compared to non CAM users. The most common type of herbs used was akar kayu bunga Fatimah (37.7%) and gamat (13.4%). In our study, usage of selusuh product and akar kayu bunga Fatimah had a significant impact in achieving vaginal delivery and shortened the duration of labour particularly in multiparae. The usage of Kacip Fatimah and Salindah was associated with preterm labour (p = 0.04)Tongkat Ali herbal coffee had a significant association with hypertensive disorders in pregnancy (p = 0.011) and fetal distress (p = 0.04) Meanwhile, the usage of Jamu Mustika Ratu was significantly associated with low birth weight in grandmultiparae (p = 0.026)and spirulina was significantly associated with oligohydramnios (p = 0.04).

CONCLUSION: Usage of CAM in pregnancy in the Malaysian population is of high prevalence CAM in pregnancy has beneficial and adverse obstetric outcomes. More research is needed to establish the safety of usage of various forms of CAM in pregnancy.

Aizat WM, Ismail I, Noor NM

Adv Exp Med Biol, 2018 11 2;1102:1-9.
PMID: 30382565 DOI: 10.1007/978-3-319-98758-3_1

The central dogma of molecular biology (DNA, RNA, protein and metabolite) has engraved our understanding of genetics in all living organisms. While the concept has been embraced for many decades, the development of high-throughput technologies particularly omics (genomics, transcriptomics, proteomics and metabolomics) has revolutionised the field to incorporate big data analysis including bioinformatics and systems biology as well as synthetic biology area. These omics approaches as well as systems and synthetic biology areas are now increasingly popular as seen by the growing numbers of publication throughout the years. Several journals which have published most of these related fields are also listed in this chapter to overview their impact and target journals.
Fulltext Understanding the Role of ztor in Aging-related Diseases Using the Zebrafish Model

Khor ES, Noor SM, Wong PF

In Vivo, 2019 10 31;33(6):1713-1720.
PMID: 31662495 DOI: 10.21873/invivo.11661

The mammalian target of rapamycin (mTOR), a 289 kDa serine/threonine protein kinase of the phosphoinositide 3-kinase (PI3K)-related family is known for its role in regulating lifespan and the aging process in humans and rodents. Aging in zebrafish very much resembles aging in humans. Aged zebrafish often manifest with spinal curvature, cataracts and cognitive frailty, akin to human age-related phenotypical effects such as osteoarthritis, dwindling vision and cognitive dysfunction. However, the role of the zebrafish orthologue of mTOR, ztor, is less defined in these areas. This review paper discusses the tale of growing old in the zebrafish, the physiological roles of ztor in normal developmental processes and its involvement in the pathogenesis of aging-related diseases such as metabolic disorders and cancers.
Psychosocial stressors at work and well-being of male employees

Noor Dalila IZA, Rosnah I, Ismail NH

Med J Malaysia, 2019 04;74(2):160-167.
PMID: 31079128

INTRODUCTION: Psychosocial stressors appear to alter the state of mind and adoption of overeating behaviour, resulting in high body mass index. This study was conducted to determine the magnitude of psychosocial stressors on male employees' well-being.
METHOD: This study used secondary data retrieved from a cross-sectional study involving 492 male employees' completed data. Eligible participants completed validated questionnaires of the Psychosocial Safety Climate (PSC-12) scale, short version Demand Induced Strain Compensation (DISQ 2.1), Oldenburg Burnout Inventory - Emotional Exhaustion domain and the Three Eating Factor Questionnaire (TEFQ) -Uncontrolled Eating domain; assessing psychosocial safety climate, job demands and job resources, emotional exhaustion, and uncontrolled eating behaviour, respectively. Body mass index (BMI) was calculated based on weight and height. The research statistical model was tested by two-steps of assessment replicating partial least squares structural equation modelling (PLS-SEM).
RESULT: The results show that psychosocial stressors (psychosocial safety climate, job demands and job resources) had significant effects on emotional exhaustion (β= -0.149, p=0.004; β= 0.223, p<0.001; β= -0.127, p=0.013). Emotional exhaustion predicted by work stressors may act as a chain reaction which could result in uncontrolled eating (β=0.138, p=0.005) and high BMI (β=0.185, p<0.001). Emotional exhaustion does mediate the relationship between PSC and uncontrolled eating behaviour (β= -0.021 [95% boot CI bias corrected: -0.048, -0.002]).
CONCLUSION: The psychosocial stressors at work are significant factors for emotional exhaustion, which further signifies the positive effect on uncontrolled eating behaviour and BMI among Malaysian male employees.

Health care workers play an important role in supporting childhood vaccination as they are the most trusted source of vaccine-related information for parents. However, there is limited validated tools to measure their knowledge and attitude on childhood vaccination. This study aims to develop and validate knowledge and attitude regarding childhood vaccination (KACV) questionnaire among healthcare workers. The questionnaire was developed based on literature reviews and underwent a sequential validation process, including content, face validity and exploratory factor analysis. However, the attitude section is unidimensional and has undergone reliability analysis only. The preliminary knowledge questionnaire contains 33 items and the attitude questionnaire consists of 17 items. The preliminary KACV showed a high item Content Validity Index and Face Validity Index. The final questionnaire consists of 10 items for knowledge and 15 items for attitude. The Cronbach alpha for the knowledge and attitude section were 0.896 and 0.861, respectively. KACV is a valid and reliable tool to measure healthcare workers' knowledge and attitude on childhood vaccination.

PMID: 34752794 DOI: 10.1016/j.ijbiomac.2021.11.031

This study aimed to utilize cationic protein extracted from the Moringa oleifera seed in the fabrication of cationic starch crosslinked with magnetic nanoparticles (MagCS). Important synthesis parameters include starch to cationic protein volume ratio, magnetic nanoparticles mass fraction, reaction and crosslinking time, reaction and crosslinking temperature and crosslinker concentration. At optimum synthesis conditions, MagCS yield a 38.55% amide content, 2.46 degree of substitution, 1.1 mmol/g charge density and 78.6% crosslinking, which are much higher compared to other starch derivatives. A series of characterization analyses such as Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, elemental analysis and vibrating sample magnetometer concluded that MagCS was embedded with amide group, has high crystallinity structure, is thermally stable and shows a promising magnetic characteristic. Based on the synthesis parameters and characterization studies, the synthesis mechanism of MagCS was also postulated. The flocculation performance of MagCS was successfully assessed for the treatment of palm oil mill effluent. At optimum dosage, initial pH and settling time of 1.0 g/L, 9.0 and 15 min, the MagCS flocculant was able to remove 90.48, 83.95 and 58.19% of turbidity, color and chemical oxygen demand, respectively. This study provides an alternative eco-friendly materials in the wastewater treatment application.

Thambidorai CR, Arief H, Noor Afidah MS

Singapore Med J, 2009 Dec;50(12):e412-4.
PMID: 20087543

Localised dilatation of a segment of the intestine without any macroscopically-identifiable cause is rare, and has been reported in association with omphalocoele in only 14 children up to 2006. In most of these cases, the segmental intestinal dilatation (SID) was either diagnosed incidentally, or due to presentation with partial or complete intestinal obstruction. We report, for the first time, a 37-week-old neonate with bowel perforation in SID associated with omphalocoele. In our case, a long thin vessel that resembled the mesodiverticular vessel of a Meckel's diverticulum was present in the dilated segment, supporting the view that SID and Meckel's diverticulum may be embryologically related.

Singapore Med J, 2007 Oct;48(10):922-5.
PMID: 17909677

Thalassaemia is one of the major public health problems in Malaysia. Regular monthly blood transfusion remains the main treatment for severe thalassaemia patients. One of the complications of blood transfusion is the formation by the recipients of alloantibodies and autoantibodies against red blood cell (RBC) antigen. The purpose of this study was to determine the prevalence of RBC autoantibodies among multiple-transfused thalassaemic patients in our institution and factors that contribute to its development.

PMID: 36969790 DOI: 10.1055/s-0040-1718512

Congenital knee dislocation (CKD) is a rare malformation characterized by hyperextension deformity of the knee with anterior tibia displacement, present at birth. Rarely reported, CKD might occur as an isolated deformity or commonly associated with musculoskeletal abnormalities, with the most common ones being developmental dysplasia of the hip (DDH) and clubfoot. The etiology is unknown, but CKD has been associated with certain intrinsic and extrinsic factors. Treatment with conservative methods at an early stage is most likely to yield successful results. We report here a rare case of successful spontaneous reduction of CKD in an infant within 24 hours of life.

Zaidun Z, Sutan R, Noor Aizuddin A

Belitung Nurs J, 2023;9(3):287-292.
PMID: 37492756 DOI: 10.33546/bnj.2652

BACKGROUND: Malaysia is projected to become an aged country by 2030, with the older age group comprising 10 percent of the total population. To address this demographic shift, comprehensive plans and initiatives are being implemented at various levels, ranging from the government to local communities. A crucial aspect of these efforts is community empowerment, which requires a reliable and validated tool for measurement.
OBJECTIVE: This study aimed to validate the Individual Community Related Empowerment (ICRE) scale in alignment with the national language of Malaysia.
METHODS: This cross-sectional study was conducted from May to December 2019. Back-to-back translation from the English to Malay version of the ICRE scale was done. A total of 328 older persons aged 60 years old and above who attended clinics and understood Malay had been randomly selected. Exploratory factor analysis (EFA), particularly Principal Component Analysis (PCA) with Varimax rotation and Kaiser Normalization, was performed in this study using IBM SPSS version 27 Amos graphic.
RESULTS: The findings revealed that the Malay version of the Individual Community Related Empowerment (ICRE-m) scale consists of five components: self-efficacy, intention, participation, motivation, and critical awareness, which collectively accounted for 92.3% of total variance. All five components demonstrated Cronbach's alpha values greater than 0.7, indicating the reliability of the selected items for field studies.
CONCLUSION: The ICRE-m scale is acceptable for field studies and valid for measuring individual-related community empowerment. Nurses and other healthcare professionals can employ this scale specifically within the Malay-speaking population, particularly in the Asian region. Future studies on community empowerment among older individuals can utilize this tool to assess community readiness for participating in community health interventions.
