    Rawi MH, Abdullah A, Ismail A, Sarbini SR
    ACS Omega, 2021 Jul 20;6(28):17782-17797.
    PMID: 34308014 DOI: 10.1021/acsomega.1c00302
    Acacia gum (AG) is a branched-polysaccharide gummy exudate that consists of arabinose and galactose. The traditional practice in African-Middle Eastern countries uses this gum as medicine. Traditional use of AG is to treat stomach disease, which can be a potential functional food. In this research, commercially available AG from Acacia senegal and Acacia seyal was investigated as the prebiotic. The experiment employed a pH-controlled in vitro colon model inoculated with human fecal microbiota to mimic the human colon. Fermentation samples at 0, 6, 12, and 24 h were brought for short-chain fatty acid (SCFA) analysis using high-performance liquid chromatography and bacterial enumeration via fluorescent in situ hybridization. Results showed that AG significantly promotes Bifidobacteria proliferation similar to fructo-oligosaccharides (FOS) while inhibiting the Clostridium histolyticum group, commonly associated with gut dysbiosis. Acetate, propionate, and butyrate showed a similar trend to FOS (p > 0.05). The AG shows potential against gut dysbiosis, as it promotes gut-probiotics, through modulation of microbial population and SCFA production, especially butyrate.

    Objective: School bullying in Malaysia is on the rise. While efforts are put together to combat the problem, the psychiatric aspect has been neglected. This is a cross-sectional study aimed to determine the association between the symptoms of ADHD and bully/victim problems among Malaysian sixthgraders attending primary schools in Kuala Lumpur.
    Methods: A total of 410 sixth-graders from seven randomly selected schools were assessed with regards to bully/victim problems and ADHD symptoms using self-reported questionnaires. Malaysian Bullying Questionnaire was used to rate bully/victim problems while ADHD symptoms were assessed using ConnersWells’ Adolescent Self-report Scale (CASS). Teachers and parents also assessed students’ ADHD symptoms using Conner’s Teachers Rating Scale (CTRS) and Conner’s Parents Rating Scale (CPRS), respectively.
    Results: Self-reported questionnaires showed that 61.2% of the children were involved in bully/victim problems. The ADHD symptoms were found significant in relation to bully/victim problems as tested by multiple logistic regression. Only students and parents reported significant ADHD symptoms among the bully/victim groups. The ADHD symptoms reported by students were significant among bullies(OR=0.59,CI=0.42-0.83, p

    As we move towards the knowledge (K) era, the challenge in R&D is to focus on the development of original K-based products that can compete in the global market. The development of commercially viable, patented K-based products within a university environment require an innovation system and innovation policies in place and a change in the paradigm towards the approach to research. A crucial agent towards the success of the innovation system is development and training of the human capital that would be the future drivers of the K-industry. Awareness of intellectual property rights, the need for original research, entrepreneurship as well as the development and strengthening of self-confidence and leadership are among the factors needed towards the training of K-workers facing the new economy.
  4. Rapid and reliable serological diagnosis of enteric fever: comparative sensitivity and specificity of Typhidot and Typhidot-M tests in febrile Malaysian children

    PMID: 10206117
    The Typhidot test, which detects IgM and IgG antibodies to a Salmonella typhi-specific outer membrane protein, is as sensitive as, and more specific than, the Widal test in the diagnosis of enteric fever in Malaysian children. It is easier and quicker to perform. In order to increase diagnostic accuracy in an area of high endemicity, the Typhidot-M test has been developed in which IgG is first removed. This theoretically allows improved detection of IgM, and thus would differentiate new from recent infections. We evaluated both tests in 134 unselected febrile children admitted to the General Hospital Kota Bharu, Malaysia. The children were divided into two groups: (i) those who were blood and/or stool culture positive for S. typhi and/or who had clinical features strongly suggestive of enteric fever (n = 62); and (ii) those who were both culture-negative and had clinical evidence of another diagnosis (n = 72). The sensitivity and specificity of the Typhidot and Typhidot-M tests were identical at 90.3 and 93.1%, respectively. Both tests had comparable sensitivity but greater specificity than those of the Widal test (91.9 and 80.6%, respectively). When used together, a positive result for Typhidot and/or Typhidot-M was more specific than either test alone (95.2%) but specificity was lower (87.5%). We conclude that the Typhidot and Typhidot-M tests have comparatively high diagnostic accuracy, suggesting that IgM can be detected in children who may have a predominant IgG response to S. typhi. Using these tests in combination increases the negative predictive value but at the cost of a lower positive predictive value.
  5. Influence of Maternal Characteristics during Pregnancy on the Infant Early Life Immune Responses in a High HIV Burdened Setting in Harare, Zimbabwe
    Nhidza AF, Naicker T, Stray-Pedersen B, Gumbo F, Chisango T, Sibanda E, et al.
    Afr J Reprod Health, 2018 Sep;22(3):43-50.
    PMID: 30381931 DOI: 10.29063/ajrh2018/v22i3.5
    This study aimed at investigating the maternal characteristics that in turn influence the immunological status of infants in asymptomatic enteric pathogen carriers in mother baby pairs (MBPs) in a high HIV burdened population in Harare, Zimbabwe. BIOPLEX immunoassay was used to analyse serum samples from 39 MBPs for 27 cytokines and 6 immunoglobulins. The MBP were purposively selected based on HIV infection and Entamoeba histolytica carriage. Logistic regression was used to identify any link between maternal demographic and clinical data with infant cytokine and immunoglobulin levels. Maternal E. histolytica carriers were more likely to have infants with low levels of IL-12p70, FGF-basic, GM-CSF and TNF-α cytokines (OR: 0.14; 95% CI: 0.03-0.79) and high levels of IgA immunoglobulin (OR: 8.1; 95% CI: 1.45-45.06). HIV infected mothers were more likely to have infants with low levels of IgG2 (OR: 0.24; 95% CI: 0.06-1.00) and IgA (OR: 0.22; 95% CI: 0.05-0.90) immunoglobulins. Notably, it was highly likely to deliver infants with low IgG4 levels (OR: 0.24; 95% CI: 0.06-1.02) for maternal mean age above 30.38 years (Standard deviation 6.09) though not significant (p=0.05). Maternal E. histolytica asymptomatic carriage, and HIV-infection status result in low levels of pro-inflammatory cytokines IL-12p70, FGF-basic, GM-CSF and TNF-α and immunoglobulins IgG2, IgG4 and IgA on their infants.
  6. Enzyme-linked amperometric electrochemical genosensor assay for the detection of PCR amplicons on a streptavidin-treated screen-printed carbon electrode
    Yean CY, Kamarudin B, Ozkan DA, Yin LS, Lalitha P, Ismail A, et al.
    Anal Chem, 2008 Apr 15;80(8):2774-9.
    PMID: 18311943 DOI: 10.1021/ac702333x
    A general purpose enzyme-based amperometric electrochemical genosensor assay was developed wherein polymerase chain reaction (PCR) amplicons labeled with both biotin and fluorescein were detected with peroxidase-conjugated antifluorescein antibody on a screen-printed carbon electrode (SPCE). As a proof of principle, the response selectivity of the genosensor was evaluated using PCR amplicons derived from lolB gene of Vibrio cholerae. Factors affecting immobilization, hybridization, and nonspecific binding were optimized to maximize sensitivity and reduce assay time. On the basis of the background amperometry signals obtained from nonspecific organisms and positive signals obtained from known V. cholerae, a threshold point of 4.20 microA signal was determined as positive. Under the optimum conditions, the limit of detection (LOD) of the assay was 10 CFU/mL of V. cholerae. The overall precision of this assay was good, with the coefficient of variation (CV) being 3.7% using SPCE and intermittent pulse amperometry (IPA) as an electrochemical technique. The assay is sensitive, safe, and cost-effective when compared to conventional agarose gel electrophoresis, real-time PCR, and other enzyme-linked assays for the detection of PCR amplicons. Furthermore, the use of a hand-held portable reader makes it suitable for use in the field.

    PMID: 33809309 DOI: 10.3390/ani11030798
    Compound 3,4-dichloroaniline (3,4-DCA) is a metabolite of several urea herbicides and intermediate chemical of several industrial products. Moreover, 3,4-DCA has been frequently detected in aquatic ecosystems around the world. This aniline is more toxic than the parent chemicals, and it affects non-target organisms. This study evaluated a 21-day reproductive response of an emerging aquatic vertebrate model, Javanese medaka (Oryzias javanicus), exposed to 3,4-DCA. Fecundity and gonads histopathology were observed. The spawning rate and fertilisation reduced significantly in the highest exposed-group (250 µg/L). Gonadosomatic index (GSI) was significantly low in females exposed to 250 µg/L. No substantial structural alteration of male gonads. However, oocyte development and ovarian cell structure were disrupted in 250 µg/L exposed females. The gonadal developmental was not affected in the males; however, a significant reduction in the developmental of female gonads was observed at 250 µg/L. These results show that 3,4-DCA interfere with the reproduction of Javanese medaka through fecundity and alteration of gonadal tissues.
  8. Fulltext Rare presentation of idiopathic duodenoduodenal intussusception
    Loo GH, Mohamad Abu Zeid WM, Lim SL, Ismail AM
    Ann R Coll Surg Engl, 2017 Jul;99(6):e188-e190.
    PMID: 28660832 DOI: 10.1308/rcsann.2017.0104
    Enteroenteric intussusception is a condition in which the full-thickness bowel wall becomes telescoped into the lumen of distal bowel. Intussusception in adult occurs infrequently and varies from childhood intussusception, particularly in its presentation, aetiology and treatment. Duodenoduodenal intussusception is rare because the duodenum is fixed in the retroperitoneal position. It usually occurs secondary to tumour, lipoma, Brunner's gland hamartomatous polyp or adenoma. The diagnosis in adults is usually made at laparotomy, where presentation is with intestinal obstruction. In non-emergency presentation, it may be difficult to arrive at an accurate diagnosis as symptoms may be vague, self-limiting intermittent abdominal pain. Clinical examinations and investigations may not be conclusive and another working diagnosis such as irritable bowel syndrome would be made. We describe a case where a patient initially presented with symptoms mimicking pancreatitis but his symptoms persisted over the course of 2 weeks. When a laparotomy was performed, duodenoduodenal intussusception was discovered and confirmed with histopathology. In this case, a discernible leading point could not be identified.
  9. Fulltext The Effectiveness of Rambutan (Nephelium lappaceum L.) Extract in Stabilization of Sunflower Oil under Accelerated Conditions
    Mei WS, Ismail A, Esa NM, Akowuah GA, Wai HC, Seng YH
    Antioxidants (Basel), 2014;3(2):371-86.
    PMID: 26784877 DOI: 10.3390/antiox3020371
    The oxidative properties of sunflower oil supplemented with rambutan extract, (crude extract and its fractionated fraction, SF II) in comparison with synthetic antioxidant were investigated. The supplemented sunflower oils were stored under accelerated conditions for 24 days at 60 °C. For every 6-day interval, the oxidative properties of the supplemented sunflower oil were evaluated based on the following tests, namely peroxide value, p-anisidine value, Thiobarbituric Acid Reactive Substances (TBARS) assay, iodine value and free fatty acids. The total oxidation (TOTOX) values were also calculated based on the peroxide values and p-anisidine values. Rambutan extract is a potential source of antioxidant. The oxidative activities of the extracts at all concentrations were significantly (p < 0.05) higher than the control. Generally, the partially fractionated fraction was more effective than the crude extract. With a 2-year storage period at ambient temperature, the fractionated fraction of the extract, SF II at 300 ppm, was observed to work more effectively than the synthetic antioxidant, t-Tocopherol, and it possessed a protective effect comparable with butylatedhydrioxynanisole (BHA). Therefore, rambutan extract could be used as a potential alternative source of antioxidant in the oil industry or other fat-based products to delay lipid oxidation.
  10. Isolation and characterization of a mo -reducing bacterium
    Ghani B, Takai M, Hisham NZ, Kishimoto N, Ismail AK, Tano T, et al.
    Appl Environ Microbiol, 1993 Apr;59(4):1176-80.
    PMID: 16348915
    A Mo -reducing bacterium (strain 48), which grew on medium supplemented with 200 mM Mo, was isolated from stream water obtained from Chengkau, Malaysia. The chemical properties of strain 48 conform to the characteristics of Enterobacter cloacae. Under anaerobic conditions in the glucose-yeast extract medium containing phosphate ion (2.9 mM) and Mo (10 mM), the bacterium reduced Mo to form molybdenum blue. Approximately 27% of Mo added to the medium was reduced after 28 h of cultivation. The reduction of Mo with glucose as an electron donor was strongly inhibited by iodoacetic acid, sodium fluoride, and sodium cyanide, suggesting an involvement of the glycolytic pathway and electron transport in Mo reduction. NADH and N,N,N',N' -tetramethyl-p-phenylenediamine served as electron donors for Mo reduction. When NADH was used as an electron donor, at first cytochrome b in the cell extract was reduced, and then molybdenum blue was formed. Sodium cyanide strongly inhibited Mo reduction by NADH (5 mM) but not the reduction of cytochrome b in the cell extract, suggesting that the reduced component of the electron transport system after cytochrome b serves as an electron donor for Mo reduction. Both ferric and stannous ions strongly enhanced the activity of Mo reduction by NADH.
  11. Overexpression, purification and validation of antigenic Salmonella enterica serovar Typhi proteins identified from LC-MS/MS
    Chin CF, Teh BA, Anthony AA, Aziah I, Ismail A, Ong EB, et al.
    Appl Biochem Biotechnol, 2014 Nov;174(5):1897-906.
    PMID: 25149461 DOI: 10.1007/s12010-014-1173-y
    In our earlier study, an immunoblot analysis using sera from febrile patients revealed that a 50-kDa band from an outer membrane protein fraction of Salmonella enterica serovar Typhi was specifically recognized only by typhoid sera and not sera from other febrile illnesses. Here, we investigated the identities of the proteins contained in the immunogenic 50-kDa band to pinpoint antigens responsible for its immunogenicity. We first used LC-MS/MS for protein identification, then used the online tool ANTIGENpro for antigenicity prediction and produced recombinant proteins of the lead antigens for validation in an enzyme-linked immunosorbent assay (ELISA). We found that proteins TolC, GlpK and SucB were specific to typhoid sera but react to antibodies differently under native and denatured conditions. This difference suggests the presence of linear and conformational epitopes on these proteins.
  12. Metabolite Variation in Lean and Obese Streptozotocin (STZ)-Induced Diabetic Rats via (1)H NMR-Based Metabolomics Approach
    Abu Bakar Sajak A, Mediani A, Maulidiani, Ismail A, Abas F
    Appl Biochem Biotechnol, 2017 Jun;182(2):653-668.
    PMID: 27995574 DOI: 10.1007/s12010-016-2352-9
    Diabetes mellitus (DM) is considered as a complex metabolic disease because it affects the metabolism of glucose and other metabolites. Although many diabetes studies have been conducted in animal models throughout the years, the pathogenesis of this disease, especially between lean diabetes (ND + STZ) and obese diabetes (OB + STZ), is still not fully understood. In this study, the urine from ND + STZ, OB + STZ, lean/control (ND), and OB + STZ rats were collected and compared by using (1)H NMR metabolomics. The results from multivariate data analysis (MVDA) showed that the diabetic groups (ND + STZ and OB + STZ) have similarities and dissimilarities for a certain level of metabolites. Differences between ND + STZ and OB + STZ were particularly noticeable in the synthesis of ketone bodies, branched-chain amino acid (BCAA), and sensitivity towards the oral T2DM diabetes drug metformin. This finding suggests that the ND + STZ group was more similar to the T1DM model and OB + STZ to the T2DM model. In addition, we also managed to identify several pathways and metabolism aspects shared by obese (OB) and OB + STZ. The results from this study are useful in developing drug target-based research as they can increase understanding regarding the cause and effect of DM.
  13. Double Brillouin frequency shift through circulation of odd-order Stokes signal
    Shee YG, Al-Mansoori MH, Ismail A, Hitam S, Mahdi MA
    Appl Opt, 2010 Jul 10;49(20):3956-9.
    PMID: 20648173 DOI: 10.1364/AO.49.003956
    We demonstrate a simple configuration for generating a double Brillouin frequency shift through the circulation of an odd-order Brillouin Stokes signal. It is operated based on cascaded Brillouin scattering in single-mode optical fibers that behave as the Brillouin gain media. A four-port circulator is incorporated into the setup to circulate the odd-order Brillouin Stokes signal in the fiber. It thus initiates a higher order Brillouin Stokes signal, which is double Brillouin frequency downshifted from the input signal. For the 5 km long fiber, the Brillouin pump power at 23 mW gives a clean output spectrum with 30 dB sideband suppression ratio. The output signal is 0.174 nm or approximately 21.7 GHz downshifted from the input signal.
  14. Fulltext Effectiveness of traditional Malaysian vegetables (ulam) in modulating blood glucose levels
    Bachok MF, Yusof BN, Ismail A, Hamid AA
    Asia Pac J Clin Nutr, 2014;23(3):369-76.
    PMID: 25164446 DOI: 10.6133/apjcn.2014.23.3.01
    Ulam refers to a group of traditional Malaysian plants commonly consumed as a part of a meal, either in the raw form or after a short blanching process. Many types of ulam are thought to possess blood glucose-lowering properties, but relatively little is known on the effectiveness of ulam in modulating blood glucose levels in humans. This review aims to systematically evaluate the effectiveness of ulam in modulating blood glucose levels in humans. A literature review was conducted using multiple databases with no time restriction. Eleven studies were retrieved based on a priori inclusion and exclusion criteria. In these 11 studies, only Momordica charantia, locally known as "peria katak", was extensively studied, followed by Centella asiatica, locally known as "daun pegaga", and Alternanthera sessilis, locally known as "kermak putih". Of the 11 studies, 9 evaluated the effectiveness of M. charantia on blood glucose parameters, and 7 of which showed significant improvement in at least one parameter of blood glucose concentration. The remaining 2 studies reported nonsignificant improvements in blood glucose parameters, despite having high-quality study design according to Jadad scale. None of the studies related to C. asiatica and A. sessilis showed significant improvement in blood glucose-related parameters. Current clinical evidence does not support the popular claim that ulam has glucose-lowering effects, not even for M. charantia. Hence, further clinical investigation is needed to verify the glucose modulation effect of M. charantia, C. asiatica, and A. sessilis.
  15. Identification of carriers among individuals recruited in the typhoid registry in Malaysia using stool culture, polymerase chain reaction, and dot enzyme immunoassay as detection tools
    Chua AL, Aziah I, Balaram P, Bhuvanendran S, Anthony AA, Mohmad SN, et al.
    Asia Pac J Public Health, 2015 Mar;27(2):NP2740-8.
    PMID: 23000800 DOI: 10.1177/1010539512458521
    Chronic carriers of Salmonella Typhi act as reservoirs for the organism and become the agents of typhoid outbreaks in a community. In this study, chronic carriers in Kelantan, Malaysia were first identified using the culture and polymerase chain reaction method. Then, a novel serological tool, designated Typhidot-C, was evaluated in retrospect using the detected individuals as control positives. Chronic carriage positive by the culture and polymerase chain reaction method was recorded at 3.6% (4 out of 110) among individuals who previously had acute typhoid fever and a 9.4% (10 out of 106) carriage rate was observed among food handlers screened during outbreaks. The Typhidot-C assay was able to detect all these positive carriers showing its potential as a viable carrier screening tool and can be used for efficient detection of typhoid carriers in an endemic area. These findings were used to establish the first carrier registry for S Typhi carriers in Malaysia.
  16. Whole-Exome Sequencing of ETV6/RUNX1 in Four Childhood Acute Lymphoblastic Leukaemia Cases
    Zakaria Z, Othman N, Ismail A, Kamaluddin NR, Esa E, Abdul Rahman EJ, et al.
    Asian Pac J Cancer Prev, 2017 04 01;18(4):1169-1175.
    PMID: 28548470
    Background: ETV6/RUNX1 gene fusion is the most frequently seen chromosomal abnormality in childhood acute
    lymphobastic leukamia (ALL). However, additional genetic changes are known to be required for the development of
    this type of leukaemia. Therefore, we here aimed to assess the somatic mutational profile of four ALL cases carrying the
    ETV6/RUNX1 fusion gene using whole-exome sequencing. Methods: DNA was isolated from bone marrow samples
    using a QIAmp DNA Blood Mini kit and subsequently sequenced using the Illumina MiSeq system. Results: We
    identified 12,960 to17,601 mutations in each sample, with a total of 16,466 somatic mutations in total. Some 15,533
    variants were single nucleotide polymorphisms (SNPs), 129 were substitutions, 415 were insertions and 389 were
    deletions. When taking into account the coding region and protein impact, 1,875 variants were synonymous and 1,956
    were non-synonymous SNPs. Among non-synonymous SNPs, 1,862 were missense, 13 nonsense, 35 frameshifts, 11
    nonstop, 3 misstart, 15 splices disrupt and 17 in-frame indels. A total of 86 variants were located in leukaemia-related
    genes of which 32 variants were located in the coding regions of GLI2, SP140, GATA2, SMAD5, KMT2C, CDH17,
    CDX2, FLT3, PML and MOV10L1. Conclusions: Detection and identification of secondary genetic alterations are
    important in identifying new therapeutic targets and developing rationally designed treatment regimens with less
    toxicity in ALL patients.

    Zakaria KN, Amid A, Zakaria Z, Jamal P, Ismail A
    Asian Pac J Cancer Prev, 2019 Feb 26;20(2):563-567.
    PMID: 30803221
    Problem statement: Clinicanthus nutans has been used by Malaysian since long time ago. It is used to treat many diseases including cancer. Many studies carried out on its crude extract but no clear report on the specific secondary metabolites responsible for its nature in treating selected diseases. Objective: This study aims to confirm the practice carried out by many people on the usage of Clinicanthus nutans in treating cancer. Methods: C. nutans leaves were extracted by methanol. Thin layer chromatography was used to identify the suitable solvent for fractions separation. The fractions were then separated at larger volume using gravity column chromatography. Each fraction was tested on its anti-proliferative activity on Hep-G2 liver cancer cells by MTT assay. The phytochemical screening was carried out to identify the bioactive compound based on qualitative analysis. Results: The fraction 2 (F2) of C. nutans showed the lowest IC50 value of 1.73 μg/ml against Hep-G2 cancer cells, and it is identified as triterpenes. Conclusion: The fraction F2 identified as triterpenes isolated from C. nutans has potential as an anti-proliferative agent against liver cancer.
