    In this study, the impact of different oxidizing agents on the structural integrity of activated carbon (AC) and multiwalled carbon nanotubes (MWCNTs) was studied for the removal of BTX from aqueous solution. Seven different combinations of green oxidizing agents (mild organic acids) in conjugation with NaOCl (basic oxidizing agent) were used. The modified adsorbents were analyzed by Brunauer, Emmett, and Teller (BET) surface area analyzer, Fourier transform infrared spectroscopy (FTIR), Boehm titration, Raman spectroscopy, thermal gravimetric analysis (TGA), x-ray diffraction (XRD), zeta potential, and variable pressure field emission scanning electron microscope (VPFESEM). The results suggested that the carbonaceous sorbents modified with combination of citric acid tartaric acid, malic acid and salicylic acid (CTMS-I) showed increased surface area (O-AC: 871.67 m2/g, O-MWCNTs: 336.37 m2/g) and total pore volume (O-AC: 0.59 cm3/g, O-MWCNTs: 0.04 cm3/g), with the significantly improved thermal stability. Preliminary batch adsorption experiments conducted using the present prepared O-AC and O-MWCNTs, showed an improved performance towards the adsorption of BTX, compared with other available reported adsorbents in the literature.

    In low concentration, fluoride is considered a necessary compound for human health. Exposure to high concentrations of fluoride is the reason for a serious disease called fluorosis. Fluorosis is categorized as Skeletal and Dental fluorosis. Several Asian countries, such as India, face contamination of water resources with fluoride. In this study, a comprehensive overview on fluoride contamination in Asian water resources has been presented. Since water contamination with fluoride in India is higher than other Asian countries, a separate section was dedicated to review published articles on fluoride contamination in this country. The status of health effects in Asian countries was another topic that was reviewed in this study. The effects of fluoride on human organs/systems such as urinary, renal, endocrine, gastrointestinal, cardiovascular, brain, and reproductive systems were another topic that was reviewed in this study. Different methods to remove fluoride from water such as reverse osmosis, electrocoagulation, nanofiltration, adsorption, ion-exchange and precipitation/coagulation were introduced in this study. Although several studies have been carried out on contamination of water resources with fluoride, the situation of water contamination with fluoride and newly developed technology to remove fluoride from water in Asian countries has not been reviewed. Therefore, this review is focused on these issues: 1) The status of fluoride contamination in Asian countries, 2) health effects of fluoride contamination in drinking water in Asia, and 3) the existing current technologies for defluoridation in Asia.

    The present work aims to optimise chicken skin gelatine/carboxymethyl cellulose (CMC) blended film formulation at varying concentrations of CMC and plasticiser (glycerol). The influence of CMC and plasticiser concentrations on the mechanical (tensile strength, TS and elongation at break, EAB) and physical (water vapour permeability, WVP) properties of chicken skin gelatine films were studied using central composite design (CCD), a full factorial design with all combinations of the factors at two levels (high, +1, and low, −1 levels), with the centre points (coded level 0) repeated thrice. An optimised formulation obtained as a proportional mixture of CMC (3%) and glycerol (0.78%), with tensile strength of 0.08 MPa, elongation at break of 167.57 and water vapour permeability of 6.08 × 10-9 g m-1s-1Pa-1. A formulation with 3% CMC and 0.78% glycerol yielded high TS and EAB, but lower WVP, which is desirable for production of food packaging. This novel research offers the packaging industry an alternative source for producing biodegradable food packaging films which are more cost-effective and at the same time reduce environmental problems.

    Primary amoebic meningoencephalitis (PAM), a deadly brain infection, is caused by brain-eating amoeba Naegleria fowleri. The current first line of treatment against PAM is a mixture of amphotericin B, rifampin, and miltefosine. Since, no single effective drug has been developed so far, the mortality rate is above 95%. Moreover, severe adverse side effects are associated with these drugs. Nanotechnology has provided several advances in biomedical applications especially in drug delivery and diagnosis. Herein, for the first time we report antiamoebic properties of cinnamic acid (CA) and gold nanoparticles conjugated with CA (CA-AuNPs) against N. fowleri. CA-AuNPs were successfully synthesized by sodium borohydride reduction of tetrachloroauric acid. Size and morphology were determined by atomic force microscopy (AFM) while the surface plasmon resonance band was analyzed by ultraviolet-visible (UV-vis) spectrophotometry for the characterization of the nanoparticles. Amoebicidal and cytopathogenicity (host cell cytotoxicity) assays revealed that both CA and CA-AuNPs displayed significant anti- N. fowleri properties ( P < 0.05), whereas nanoparticles conjugation further enhanced the anti- N. fowleri effects of CA. This study established a potential drug lead, while CA-AuNPs appear to be promising candidate for drug discovery against PAM.

    BACKGROUND: There is a limited understanding about the oral health of patients with facial burn, hence the aim was to describe the oral health status and the related risks factors.

    METHODS: This cross-sectional study had randomly and systematically recruited facial burn patients from the Burn Care Center, Pakistan Institute of Medical Sciences, Islamabad, from June of 2016 to July of 2017. Intraoral examination recorded the DMFT, CPI and OHI-S. Information on the socio-demographic status, self-perceived oral health, oral health behaviours were collected using a self-administered questionnaire and; the burn characteristics were obtained from the patients' medical record. The t-test, ANOVA, SLR, and chi-square test were used to examine the relationship between oral health and each factor. A parameter was derived from the clinical indices using the principal component analysis and used in the multiple linear regression analysis to determine the important factors associated with oral health status.

    RESULTS: A total of 271 burn patients (69% female and 31% male) had participated in the study. All of the participants had caries with mean DMFT = 10.96 (95%CI: 10.67, 11.25). There were 59.0% (95%CI: 53.15, 64.93%) and 66.1% (95%CI: 60.38, 71.73%) of the participants who had periodontitis and poor oral hygiene respectively. About 79 and 80% of the participants rated their dental and periodontal status as poor. About 78% reported brushing once daily and 89% did not practice regular dental visit. The DMFT, CPI and OHI-S were associated with the burn characteristics and oral health behaviours (p

    INTRODUCTION: Cancer related fatigue (CRF) is a problem experienced by head and neck cancer patients, especially those who undergo chemoradiation therapy. CRF may persist for years post chemoradiation therapy and significantly impair their quality of life (QOL). Tualang honey is rich in amino acids, vitamins, minerals and enzymes. It is proven to have anti-inflammatory, antioxidant and anti-tumour properties. As CRF is related to inflammatory mediators, the effects of Tualang Honey may improve CRF. The aim of this study is to determine if Tualang honey has a role in improving CRF and quality of life among head and neck cancer patients post chemoradiation.

    METHODOLOGY: In this open labelled randomized clinical trial, 40 participants aged between 18 and 65 with head and neck cancer who completed chemotherapy and/or radiotherapy in Hospital USM, Kelantan Malaysia or Hospital Taiping were recruited and randomized into two groups: Tualang honey (experimental) group or Vitamin C (control) group. They were prescribed with either daily oral Tualang honey 20mg or vitamin C tablet 100 mg for 8 weeks. Level of fatigue and quality of life were measured using FACIT-Fatigue and FACT H&N questionnaires at baseline, 4 weeks and 8 weeks. The white cell count and C-reactive protein level were also measured at baseline, 4 weeks and 8 weeks.

    RESULTS: After four and eight weeks of treatment with Tualang honey or Vitamin C, the fatigue level for experimental group was better than in the control group, and the differences were statistically significant (p<0.05). Statistically significant improvements were seen on quality of life (p<0.05) for the experimental group at week 8, however, no significant improvements were seen in white cell count and C-reactive protein level between control and experimental group.

    CONCLUSION: Our research provided support for the use of Tualang honey to improve CRF and QOL in head and neck cancer patients post chemotherapy or radiotherapy.

    Dietary antioxidant supplements such as L-glutathione have gained considerable attention in dermatology and cosmeceutical fields. L-glutathione possesses antiaging, antimelanogenic, antioxidant, and anticancer properties. This study aimed to investigate the inhibitory effects of L-glutathione on melanogenesis activity and oxidative stress in ultraviolet B (UVB)-irradiated BALB/c mice. Eighteen female BALB/c mice were randomly divided into 3 groups: a control group (n=6), a group without UVB irradiation and L-glutathione administration; a UVB irradiated group (n=6), a group irradiated with a UVB dose of 250 mJ/cm2 for 3 min; and a treatment group (n=6), a group irradiated with UVB and treated with 100 mg/kg of L-glutathione by oral gavage. Treatment was given for 14 days, and UVB irradiation was given on days 9, 11, and 13. Oral L-glutathione significantly (P<0.05) reduced lipid peroxidation and elevated superoxide dismutase activity the and glutathione level. L-glutathione also inhibited melanin content and tyrosinase activity significantly (P<0.05) as compared with the UVB-irradiated group. Histopathological examination also showed that L-glutathione reduced the deposition of melanin pigment in the basal layer of the epidermis as compared with that in UVB-irradiated mice. All in all, the present study demonstrated that L-glutathione has the potential to be developed as a photoprotection agent against UVB-induced oxidative stress and melanogenesis.

    BACKGROUND: Using non-statin lipid-modifying agents in combination with statin therapy provides additional benefits for cardiovascular disease (CVD) risk reduction, but their value for money has only been evaluated in high-income countries (HICs). Furthermore, studies mainly derive effectiveness data from a single trial or older meta-analyses.

    OBJECTIVES: Our study used data from the most recent network meta-analysis (NMA) and local parameters to assess the cost effectiveness of non-statin agents in statin-treated patients with a history of CVD.

    METHODS: A published Markov model was adopted to investigate lifetime outcomes: (1) number of recurrent CVD events prevented, (2) quality-adjusted life-years (QALYs) gained, (3) costs and (4) incremental cost-effectiveness ratios (ICERs) of proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) and ezetimibe added to statin therapy. Event rates and effectiveness inputs were obtained from the NMA. Cost and utility data were gathered from published studies conducted in Thailand. A series of sensitivity analyses were performed.

    RESULTS: Patients receiving PCSK9i and ezetimibe experienced fewer recurrent CVD events (number needed to treat [NNT] 17 and 30) and more QALYs (0.168 and 0.096 QALYs gained per person). However, under the societal perspective and at current acquisition costs in 2018, ICERs of both agents were $US1,223,995 and 27,361 per QALY gained, respectively. Based on threshold analyses, the costs need to be reduced by 97 and 85%, respectively, for PCSK9i and ezetimibe to be cost-effective.

    CONCLUSIONS: Despite the proven effectiveness of PCSK9i and ezetimibe, the costs of these agents need to reduce to a much greater extent than in HICs to be cost-effective in Thailand.

    Inflammatory conditions are frequently accompanied by increased levels of active proteases, and there is rising interest in methods for their detection to monitor inflammation in a point of care setting. In this work, new sensor materials for disposable single-step protease biosensors based on poly(2-oxazoline) hydrogels cross-linked with a protease-specific cleavable peptide are described. The performance of the sensor material was assessed targeting the detection of matrix metalloproteinase-9 (MMP-9), a protease that has been shown to be an indicator of inflammation in multiple sclerosis and other inflammatory conditions. Films of the hydrogel were formed on gold-coated quartz crystals using thiol-ene click chemistry, and the cross-link density was optimized. The degradation rate of the hydrogel was monitored using a quartz crystal microbalance (QCM) and showed a strong dependence on the MMP-9 concentration. A concentration range of 0-160 nM of MMP-9 was investigated, and a lower limit of detection of 10 nM MMP-9 was determined.

    Each year, many countries from developed world publishes reports on early cancer detection; which is absolutely
    absent in most developing countries like Bangladesh.Very limited evidence is found on the role and acceptance of Pap
    test among the women of Bangladesh in determining cervical cancer. More research and updates are needed relating Pap
    test in early detection of cervical cancer. Thus the purpose of this study is set to assess the opinions of Bangladeshiurban
    womentowardsthe Pap test. A questionnaire-based survey of 400 Bangladeshi urban women was evaluated by on their
    socio-demographic characteristics, knowledgeand attitudes towards Pap testing. In general, the findings reveal that
    respondents havea good understanding of thepurpose of Pap test screening with 3.92 (Mean score). With 3.54 Mean
    score,the respondents believed that Pap tests are recommended to women who are married and with 3.45 mean score
    women believed that Pap tests arerecommended only to those who have children. Generally, respondents possess good
    knowledge of Pap test and its purpose. These findings can be used in identifying prospect cervical cancer screening
    significance populations and trend for future intrusion.

    AIM: To investigate the frequencies and association of polymorphic genotypes of IL-8 -251 T>A, TNF-α -308
    G>A, ICAM-1 K469E, ICAM-1 R241G, IL-6 -174 G>C, and PPAR-γ 34 C>G in modulating susceptibility risk in
    Malaysian colorectal cancer (CRC) patients. Methods: In this case-control study, peripheral blood samples of 560
    study subjects (280 CRC patients and 280 controls) were collected, DNA extracted and genotyped using PCR-RFLP
    and Allele Specific PCR. The association between polymorphic genotype and CRC susceptibility risk was determined
    using Logistic Regression analysis deriving Odds ratio (OR) and 95% CI. Results: On comparing the frequencies of
    genotypes of all single nucleotide polymorphisms ( SNPs ) in patients and controls, the homozygous variant genotypes
    IL-8 -251 AA and TNF-α -308 AA and variant A alleles were significantly higher in CRC patients. Investigation on
    the association of the variant alleles and genotypes singly, with susceptibility risk showed the homozygous variant A
    alleles and genotypes IL-8 -251 AA and TNF-α -308 AA to be at higher risk for CRC predisposition. Analysis based
    on age, gender and smoking habits showed that the polymorphisms IL8 -251 T>A and TNF – α 308 G>A contribute
    to a significantly higher risk among male and female who are more than 50 years and for smokers in this population.
    Conclusion: We observed an association between variant allele and genotypes of IL-8-251 T>A and TNF-α-308
    G>A polymorphisms and CRC susceptibility risk in Malaysian patients. These two SNPs in inflammatory response
    genes which undoubtedly contribute to individual risks to CRC susceptibility may be considered as potential genetic
    predisposition factors for CRC in Malaysian population.

    Objective: This report focuses on a private medical centre cancer care performance as measured by patient survival
    outcome for up to 5 years. Methods: All patients with nasopharyngeal cancer treated at SJMC between 2008 and 2012
    were enrolled for this observational cohort study. Mortality outcome was ascertained through record linkage with
    national death register, linkage with hospital registration system and finally through direct contact by phone. Result:
    266 patients treated between 2008 and 2012 were included for survival analysis. 31% of patients were diagnosed with
    Early NPC Cancer (Stage I or II), another 44% with Locally Advanced Cancer (Stage III) and 25% with late stage IV
    metastatic cancer. 2%, 27% and 67% had WHO Class I, II and III NPC respectively. The overall survival at 5 years
    was 100% for patients with Stage I disease, 91% for Stage II disease, 72% for Stage III disease, and decreasing to
    44% for Stage IV disease. Overall survival at 5 years for all stages was 73%. Conclusion: SJMC is among the first
    hospitals in Malaysia to embark on routine measurement of the performance of its cancer care services and its results
    are comparable to any leading centers in developed countries.

    Objective: The most frequent acquired molecular abnormalities and important prognostic indicators in patients
    with Acute Myeloid Leukaemia (AML) are fms-like tyrosine kinase-3 gene (FLT3) and nucleophosmin-1 (NPM1)
    mutations. Our study aims to develop a cost effective and comprehensive in-house conventional PCR method for
    detection of FLT3-ITD, FLT3-D835 and NPM1 mutations and to evaluate the frequency of these mutations in patients
    with cytogenetically normal (CN) AML in our population. Methods: A total of 199 samples from AML patients (95
    women, 104 men) were included in the study. Mutation analyses were performed using polymerase chain reaction
    (PCR) and gene sequencing. Result: Sixty-eight patients were positive for the mutations. FLT3-ITD mutations were
    detected in 32 patients (16.1%), followed by FLT3-D835 in 5 (2.5%) and NPM1 in 54 (27.1%). Double mutations of
    NPM1 and FLT3-ITD were detected in 23 cases (11.6%). Assays validation were performed using Sanger sequencing
    and showed 100% concordance with in house method. Conclusion: The optimized in-house PCR assays for the
    detection of FLT3-ITD, FLT3-D835 and NPM1 mutations in AML patients were robust, less labour intensive and cost
    effective. These assays can be used as diagnostic tools for mutation detection in AML patients since identification of
    these mutations are important for prognostication and optimization of patient care.

    Background: Breast cancer (BC) awareness is relatively poor among Malaysian women indicated by the presence of BC at a late stage and the low rate of mammography screening. Only a few theoretically based studies have been conducted on Malaysian women’s participation in mammography. Therefore, the objective of this study is to use health belief model (HBM) and stage of change model (SCM) to determine the relationship between health beliefs on the behavioral adoption of mammography amongst women in Kuantan, Pahang. Methods: Five hundred and twenty women were randomly selected to complete the survey. Data were analyzed using multinomial logistic regression (MLR) to ascertain the multivariate relationships between health beliefs and stage of mammography behavioral adoption. Results:
    The MLR test indicates that there is no significant difference in perceived severity, benefits, motivator factors and cues to action between participants in the action stage and the maintenance stage. However, significant differences existed in perceived severity, susceptibility, motivator factors and self-efficacy between the pre-contemplation, relapse and contemplation stage to that of the referenced (maintenance) stage of mammography adoption. Conclusion: Women in the action stage are more likely to progress towards maintenance stage as they perceived breast cancer as a disease that leads to death and that mammogram screening is beneficial in detecting the disease at an early stage. However, women in the pre-contemplation, relapse and contemplation stage are found unlikely to move towards the maintenance stage as they perceived their risk of getting breast cancer is low.

    The Chêneau brace has proven its effectiveness in treating the adolescent idiopathic scoliosis patients. However, no studies reported on the analysis of interface pressure in double-curve adolescent idiopathic scoliosis patients. In this study, we evaluated the interface pressure of the Chêneau brace action in double-curve adolescent idiopathic scoliosis patient treatment. A total of 72 (60 girls and 12 boys) patients aged 10 years and above participated in the study. The F-Socket transducers (9811E) were used to evaluate the pressure on the right thoracic and left thoracolumbar curves between normal and maximum strap tension and variation in these interface pressures with other tasks. Each patient was asked to do nine different tasks corresponding to daily activities, and the interface pressures for each activity were recorded for both normal and maximum tension. The resultant mean peak pressure in double-curve adolescent idiopathic scoliosis was higher for right thoracic curves than left thoracolumbar curves in all tasks. The pressure significantly increased at the task of maximal inspiration (p

    Irritable bowel syndrome (IBS) is a functional disorder which affects a large proportion of the population globally. The precise etiology of IBS is still unknown, although consensus understanding proposes IBS to be of multifactorial origin with yet undefined subtypes. Genetic and epigenetic factors, stress-related nervous and endocrine systems, immune dysregulation and the brain-gut axis seem to be contributing factors that predispose individuals to IBS. In addition to food hypersensitivity, toxins and adverse life events, chronic infections and dysbiotic gut microbiota have been suggested to trigger IBS symptoms in tandem with the predisposing factors. This review will summarize the pathophysiology of IBS and the role of gut microbiota in relation to IBS. Current methodologies for microbiome studies in IBS such as genome sequencing, metagenomics, culturomics and animal models will be discussed. The myriad of therapy options such as immunoglobulins (immune-based therapy), probiotics and prebiotics, dietary modifications including FODMAP restriction diet and gluten-free diet, as well as fecal transplantation will be reviewed. Finally this review will highlight future directions in IBS therapy research, including identification of new molecular targets, application of 3-D gut model, gut-on-a-chip and personalized therapy.

    Thyroid abscesses are rare as the gland has a rich blood supply, well-developed capsule and is high in iodine. However, clinicians must be aware of this fact and make an early diagnosis as it can lead to serious morbidity if left untreated. Infection may involve one or both lobes of the thyroid gland, although the left lobe is more often affected and is successfully treated with surgery and antibiotics. This case study involves a 22-year-old woman with a history of painful swelling over the neck accompanied by low-grade fever without any underlying cause. Both the ultrasound and computed tomography revealed a heterogeneous mass within the left lobe of the thyroid gland. Fine needle aspiration revealed an abscess collection and culture Staphylococcus aureus had grown. She was successfully treated with intravenous and oral amoxicillin clavulanate and no surgical treatment was carried out. In conclusion, thyroid abscesses are rare as the gland is resistant to infection and must be differentiated from an infected branchial cleft cyst or sinus, infected thyroid tumour or lymphadenitis in the region of the thyroid in order to avoid serious morbidity if left untreated.

    Introduction: Functional electrical stimulation is a common technique used in the rehabilitation of individuals with a spinal cord injury to produce functional movement of paralysed muscles. However, it is often associated with rapid muscle fatigue which limits its applications. Methods: The objective of this study is to investigate the effects on the onset of fatigue of different multi-electrode patterns of stimulation via multiple pairs of electrodes using doublet pulses: Synchronous stimulation is compared to asynchronous stimulation patterns which are activated sequentially (AsynS) or randomly (AsynR), mimicking voluntary muscle activation by targeting different motor units. We investigated these three different approaches by applying stimulation to the gastrocnemius muscle repeatedly for 10 min (300 ms stimulation followed by 700 ms of no-stimulation) with 40 Hz effective frequency for all protocols and doublet pulses with an inter-pulse-interval of 6 ms. Eleven able-bodied volunteers (28 ± 3 years old) participated in this study. Ultrasound videos were recorded during stimulation to allow evaluation of changes in muscle morphology. The main fatigue indicators we focused on were the normalised fatigue index, fatigue time interval and pre-post twitch-tetanus ratio. Results: The results demonstrate that asynchronous stimulation with doublet pulses gives a higher normalised fatigue index (0.80 ± 0.08 and 0.87 ± 0.08) for AsynS and AsynR, respectively, than synchronous stimulation (0.62 ± 0.06). Furthermore, a longer fatigue time interval for AsynS (302.2 ± 230.9 s) and AsynR (384.4 ± 279.0 s) compared to synchronous stimulation (68.0 ± 30.5 s) indicates that fatigue occurs later during asynchronous stimulation; however, this was only found to be statistically significant for one of two methods used to calculate the group mean. Although no significant difference was found in pre-post twitch-tetanus ratio, there was a trend towards these effects. Conclusion: In this study, we proposed an asynchronous stimulation pattern for the application of functional electrical stimulation and investigated its suitability for reducing muscle fatigue compared to previous methods. The results show that asynchronous multi-electrode stimulation patterns with doublet pulses may improve fatigue resistance in functional electrical stimulation applications in some conditions.
