    The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 17 countries in Africa, Asia, Europe, Latin America and the Middle East, and interventions for achieving the Global Health Sector Strategy on viral hepatitis targets-"WHO Targets" (65% reduction in HCV-related deaths, 90% reduction in new infections and 90% of infections diagnosed by 2030) were considered. Scaling up treatment and diagnosis rates over time would be required to achieve these targets in all but one country, even with the introduction of high SVR therapies. The scenarios developed to achieve the WHO Targets in all countries studied assumed the implementation of national policies to prevent new infections and to diagnose current infections through screening.

    BACKGROUND: There is little evidence regarding risk factors for child obesity in Asian populations, including the role of parental anthropometric and cardiometabolic risk factors. We examined the relation between parental risk factors and child obesity in a Malaysian population.

    METHODS: We used data from health and demographic surveillance conducted by the South East Asia Community Observatory in Segamat, Malaysia. Analyses included 9207 individuals (4806 children, 2570 mothers and 1831 fathers). Child obesity was defined based on the World Health Organization 2007 reference. We assessed the relation between parental anthropometric (overweight, obesity and central obesity) and cardiometabolic (systolic hypertension, diastolic hypertension and hyperglycaemia) risk factors and child obesity, using mixed effects Poisson regression models with robust standard errors.

    RESULTS: We found a high burden of overweight and obesity among children in this population (30% overweight or obese). Children of one or more obese parents had a 2-fold greater risk of being obese compared with children of non-obese parents. Sequential adjustment for parental and child characteristics did not materially affect estimates (fully adjusted relative risk for obesity in both parents: 2.39, 95% confidence interval: 1.82, 3.10, P

    OBJECTIVE: Auditory brainstem responses evoked by complex stimuli such as speech syllables have been studied in normal subjects and subjects with compromised auditory functions. The stability of speech-evoked auditory brainstem response (speech-ABR) when tested over time has been reported but the literature is limited. The present study was carried out to determine the test-retest reliability of speech-ABR in healthy children at a low sensation level.

    METHODS: Seventeen healthy children (6 boys, 11 girls) aged from 5 to 9 years (mean = 6.8 ± 3.3 years) were tested in two sessions separated by a 3-month period. The stimulus used was a 40-ms syllable /da/ presented at 30 dB sensation level.

    RESULTS: As revealed by pair t-test and intra-class correlation (ICC) analyses, peak latencies, peak amplitudes and composite onset measures of speech-ABR were found to be highly replicable. Compared to other parameters, higher ICC values were noted for peak latencies of speech-ABR.

    CONCLUSION: The present study was the first to report the test-retest reliability of speech-ABR recorded at low stimulation levels in healthy children. Due to its good stability, it can be used as an objective indicator for assessing the effectiveness of auditory rehabilitation in hearing-impaired children in future studies.

    The prevalence of hypertension is very common amongst the diabetic patients and is reported as the major cause of mortality in diabetes. Pioglitazone reported to have an ability to alter the blood cholesterol level and cardioprotective efficiency along with its antidiabetic activity. Telmisartan, through activation of PPAR-γ receptor exerts insulin sensitizing property in addition to its primary cardioprotective efficiency. Theoretically, a combination of pioglitazone and telmisartan may be beneficial to effectively control the high blood glucose level and management of coexisting cardiovascular complication in diabetes. The aim of this research was to experimentally evaluate the pharmacokinetic interaction of pioglitazone and telmisartan when are coadministered in rat. Pioglitazone and telmisartan were administered orally as a single dose individually and in combination to the rats. The plasma samples of the pharmacokinetic study were analyzed using a validated LCMS method. The acute toxicity of the combination with a high dose in rats was also evaluated as a part of the determination of its safety profile. There was no significant change in pharmacokinetic parameters were resulted due to the coadministration of pioglitazone and telmisartan in rat. Absence of major toxicological effect supports the in vivosafety of the combination.

    A total of 97 amino acids, considered as the signal peptide and transmembrane segments were removed from 205y lipase gene using polymerase chain reaction technique that abolished the low activity of this enzyme. The mature enzyme was expressed in Escherichia coli using pBAD expression vector, which gave up to a 13-fold increase in lipase activity. The mature 205y lipase (without signal peptide and transmembrane; -SP/TM) was purified to homogeneity using the isoelectric focusing technique with 53% recovery. Removing of the signal peptide and transmembrane segments had resulted in the shift of optimal pH, an increase in optimal temperature and tolerance towards more water-miscible organic solvents as compared to the characteristics of open reading frame (ORF) of 205y lipase. Also, in the presence of 1mM inhibitors, less decrease in the activity of mature 205y lipase was observed compared to the ORF of the enzyme. Protein structure modeling showed that 205y lipase consisted of an α/β hydrolase fold without lid domain. However, the transmembrane segment could effect on the enzyme activity by covering the active site or aggregation the protein.

    Mucosal immunization of influenza vaccine is potentially an effective approach for the prevention and control of influenza. The objective of the present study was to evaluate the ability of oral immunization with a non-recombinant Lactococcus lactis displaying HA1/L/AcmA recombinant protein, LL-HA1/L/AcmA, to induce mucosal immune responses and to accord protection against influenza virus infection in mice. The LL-HA1/L/AcmA was orally administered into mice and the immune response was evaluated. Mice immunized with LL-HA1/L/AcmA developed detectable specific sIgA in faecal extract, small intestine wash, BAL fluid and nasal fluid. The results obtained demonstrated that oral immunization of mice with LL-HA1/L/AcmA elicited mucosal immunity in both the gastrointestinal tract and the respiratory tract. The protective efficacy of LL-HA1/L/AcmA in immunized mice against a lethal dose challenge with influenza virus was also assessed. Upon challenge, the non-immunized group of mice showed high susceptibility to influenza virus infection. In contrast, 7/8 of mice orally immunized with LL-HA1/L/AcmA survived. In conclusion, oral administration of LL-HA1/L/AcmA in mice induced mucosal immunity and most importantly, provided protection against lethal influenza virus challenge. These results highlight the potential application of L. lactis as a platform for delivery of influenza virus vaccine.

    The non-destructive feature of optical techniques has gained interests for quality assessment
    of various agricultural produce as well as in food processing technology. The principle and
    interaction of light with food and agricultural produce provide essential information for quality
    assessment which promotes non-destructive inspection methods. This review encompasses the
    determination of optical properties associated with the evaluation of the quality of agricultural
    produce. The understanding of how light interacts with turbid agricultural produce is also
    presented, including light characteristics such as absorption and scattering. A brief overview of
    the estimation and application of the optical parameters in food and agricultural processing are
    discussed. The problems and implementation of optical parameters as well as its future trend
    are also included.

    Foodborne pathogens have become a constant threat to the consumer and food industry.
    Reduce efficacy of antibiotics with emergence of resistant bacteria has limited the opportunities
    for controlling pathogenic bacteria in food commodities and treating foodborne infections.
    Bacteriophages can be a promising alternative for alleviate the risk of transmitting pathogenic
    bacteria via food commodities. Therefore, this research was conducted to find distribution of
    bacteriophages in diverse niches in order to identify suitable sources for isolating bacteriophages
    to use controlling foodborne pathogens. Firstly bacterial strains were screened for lysogenic and
    selected suitable host bacterial strains were used for isolating and determining bacteriophage titer
    in fresh raw food and environmental samples. Eighteen different lytic bacteriophages effective
    against Campylobacter, S. aureus, L. monocytogenes and E. coli were isolated from this study.
    Bacteriophages titer was determined within range of 102
    to 1010 PFU/mL and bacteriophages
    were most frequently isolated from chicken (60%) samples. The isolated bacteriophages could
    be potential candidates for controlling foodborne diseases.

    Recently researchers are interested with the biotherapeutic potential of probiotics in gut disease
    treatment. The bacteria are generally regarded as a safe, have a stability of usage and originate
    from the natural resources. The study aims to identify and characterize the potential probiotic
    Lactic Acid Bacteria (LAB) isolated from Malaysian fermented fish product known as
    Pekasam. Fourty isolates obtained were firstly screened for their antagonism activities against
    the common pathogenic bacteria; Esherichia coli, Staphylococcus aureus and Klebsiella sp.
    Our study revealed only three (labeled as L8, L20 and S1) of the isolates tested showed broad
    antimicrobial effects towards the pathogenic bacteria. All of the isolates were also γ-hemolytic
    and tolerant to various pH (pH 3, 5 and 7.5) and 0.3% (w/v) bile salts. The bacteria isolates
    of strain L8 and L20 were susceptible to seven antibiotics tested except vancomycin and
    tetracycline whereas S1 was resistant to all antibiotics. Phenotypic tests revealed that both
    bacteria isolates of strain L8 and L20 were Bacillus megaterium while S1 was Pediococcus
    pentosaceus whereas 16S rRNA gene sequence analysis showed potential bacteria isolates
    of strain L8 and L20 belonged to the Lactobacillus plantarum (99% similarity) and S1 was
    characterized as Lactobacillus pentosus (100% similarity) respectively. Our present study
    showed that the probiotics of strain L8, L20 and S1 isolated from the fermented fish (Pekasam)
    exhibited the potential probiotic properties to be developed as biotherapeutic agents.

    Ten solvents were used to extract phytochemicals from the peel of Carica papaya cv. Sekaki/
    Hong Kong to evaluate antibacterial activities and determine chemical composition of Carica
    papaya cv. Sekaki/Hong Kong seeds. The antibacterial activities of ten solvent extracts were
    tested against 14 microorganisms vis Shigella sonnei, Salmonella typhimurium, Escherichia
    coli, Salmonella enteritidis, Vibrio vulnificus, Vibrio parahaemolyticus, Proteus mirabilis,
    Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, Corynebacterium diphtheria,
    Clostridium perfringens, Streptococcus pneumoniae and Bacillus subtilis using disk diffusion
    test (DDT). The Carica papaya seed of ACN and MeOH extracts inhibited 11 microorganisms,
    indicating their broad spectrum activity. The disk diffusion test exhibited moderate and clear
    inhibition on C. diphtheria, S. pneumonia, B. subtilis and C. perfringens. MeOH extract
    inhibited S. enteritidis, V. vulnificus, P. mirabilis and B. cereus with the lowest MIC at 11.25
    mg/mL each, thus was chosen as the best extract. The hierarchy of extract potency can be
    ranked as MeOH > acetone > ACN > CHCL3 > hexane > DE = PE > EtOH > DCM based
    on clear and moderate inhibition and the lowest MIC. TPC and TFC of the extracts ranged
    between 4.83 to 22.59 mg GAE/g DW and 1.32 (water) and 17.15 mg QE/g DW respectively.
    The GC/MS analysis of MeOH extract identified potential antibacterial compounds such as
    isothiocyanatomethyl benzene, 9-octadecenoic acid, hexadecanoic acid and β-sitosterol. The
    Carica papaya seed cv. Sekaki/ Hong Kong possessed significant antibacterial activities when
    extracted by different solvents in particular MeOH solvent.

    BACKGROUND: Quality of life (QoL) assessment provides valuable outcome to support clinical decision-making, particularly for patients with chronic diseases that are incurable. A brief, 15-item diabetes-specific tool [i.e. Diabetes Quality of Life-Brief Clinical Inventory (DQoL-BCI)] is known to be developed in English and validated for use in clinical practice. This simplified tool, however, is not readily available for use in the Malaysian setting.

    OBJECTIVE: To translate the DQoL-BCI into a Malaysian version and to assess its construct validity (factorial validity, convergent validity and discriminant validity), reliability (internal consistency) and floor and ceiling effects among the Malaysian diabetic population.

    MATERIAL AND METHODS: A forward-backward translation, involving professional translators and experts with vast experience in translation of patient reported outcome measures, was conducted. A total of 202 patients with Type 2 diabetes mellitus (T2DM) who fulfilled the inclusion criteria were invited to complete the translated DQoL-BCI. Data were analysed using SPSS for exploratory factor analysis (EFA), convergent and discriminant validity, reliability and test-retest, and AMOS software for confirmatory factor analysis (CFA).

    RESULTS: Findings from EFA indicated that the 4-factor structure of the Malaysian version of DQoL-BCI was optimal and explained 50.9% of the variance; CFA confirmed the 4-factor model fit. There was negative, moderate correlation between the scores of DQoL-BCI (Malaysian version) and EQ-5D-3L utility score (r = -0.329, p = 0.003). Patients with higher glycated haemoglobin levels (p = 0.008), diabetes macrovascular (p = 0.017) and microvascular (p = 0.013) complications reported poorer QoL. Cronbach's alpha coefficient and intraclass coefficient correlations (range) obtained were 0.703 and 0.86 (0.734-0.934), indicating good reliability and stability of the translated DQoL-BCI.

    CONCLUSION: This study had validated the linguistic and psychometric properties of DQoL-BCI (Malaysian version), thus providing a valid and reliable brief tool for assessing the QoL of Malaysian T2DM patients.

    A middle-aged woman with recurrent malignant melanoma presented initially with massive left pleural effusion. There was a complete obliteration of the left main bronchus on flexible bronchoscopy caused by a mass. Serial cryo-debulking of the tumour was done under rigid bronchoscopy; however, the outcome was not favourable due to the aggressive tumour growth. Vemurafenib was planned after thoracic radiation. She was not keen for the biologics treatment due to financial constraints. We report a case of central airway obstruction due to recurrent aggressive melanoma. More evaluations are needed on the role of interventional pulmonologist for bronchoscopic debulking of this rapidly growing tumour as well as the role of biological agents in treating such cases.

    The aim of this study is to investigate the biopotency of methanolic extracts of Vitex mollis, Psidium guajava, Dalbergia retusa, and Crescential alata leaves against various staphylococcal strains isolated from cattle and rabbits. Methicillin-resistant S. aureus strains were isolated from cattle, while other strains were isolated from rabbits using standard methodology. The total phytochemical phenolic and saponins contents were obtained being the main groups of the antinutritional factors. The antimicrobial activity of the extracts against the standard culture of S. aureus (control) and S. aureus isolated from cattle and rabbits were investigated comparatively relative to that of oxacillin. It was found that both the control S. aureus and the isolated S. aureus are susceptible to all the four plant extracts, and sensitive to oxacillin. Of all the S. aureus including the control, MRSA2 is the most susceptible to all the extracts at 1000 μg/mL, except that of V. mollis where it is the least susceptible. Among all the plant extracts, P. guajava is the most active against MRSA2 and SOSA2. Therefore, the isolates from cattle (MRSA1 and MRSA2) are more susceptible to all the plant extracts than the isolates from rabbits. Among all the rabbit isolates, CoNS3 is the least susceptible to the extracts. Since all the plant extracts exhibit remarkable inhibitory activities against all the S. aureus strains, they are promising towards the production of therapeutic drugs.

    The variable development of the zygoma, dictating its shape and size variations among ancestral groups, has important clinical implications and valuable anthropological and evolutionary inferences. The purpose of the study was to review the literature regarding the variations in the zygoma with ancestry. Ancestral variation in the zygoma reflects genetic variations because of genetic drift as well as natural selection and epigenetic changes to adapt to diet and climate variations with possible intensification by isolation. Prominence of the zygoma, zygomaxillary tuberosity, and malar tubercle have been associated with Eastern Asian populations in whom these features intensified. Prominence of the zygoma is also associated with groups from Eastern Europe and the rest of Asia. Diffusion of these traits occurred across the Behring Sea to the Arctic areas and to North and South America. The greatest zygomatic projections are exhibited in Arctic groups as an adaptation to extreme cold conditions, while Native South American groups also present with other features of facial robusticity. Groups from Australia, Malaysia, and Oceania show prominence of the zygoma to a certain extent, possibly because of archaic occupations by undifferentiated Southeast Asian populations. More recent interactions with Chinese groups might explain the prominent cheekbones noted in certain South African groups. Many deductions regarding evolutionary processes and diversifications of early groups have been made. Cognisance of these ancestral variations also have implications for forensic anthropological assessments as well as plastic and reconstructive surgery. More studies are needed to improve accuracy of forensic anthropological identification techniques. Anat Rec, 300:196-208, 2017. © 2016 Wiley Periodicals, Inc.

    Fluorescence upconversion and transient absorption techniques are used to explain the source of the intense red/near-infrared emission of crystalline 4-dimethylamino-2'-hydroxychalcone. We found that the initially excited enol form undergoes tautomerization in 3 ps to form the keto tautomer. The latter is stable in the ground state as a consequence of J-type aggregation in the crystal packing and is manifested in an absorption peak at 550 nm that spectrally overlaps with the short-lived enol emission, leading to self-reabsorption and adding a factor to the complete depletion of the enol emission. Relaxation of the keto tautomer takes place in the form of intense fluorescence (600-750 nm) with 1.7 ns lifetime. The different spectroscopy in solution is due to vibrational cooling (300 fs), followed by solvation dynamics (5 ps in methanol) and twisting of the hydroxyphenyl ring (16 ps), before relaxation of the enol tautomer in the form of weak green fluorescence with 350 ps lifetime.

    BACKGROUND: In clinical practice, assessment of constipation depends on reliability, consistency and frequency of several commonly reported or core symptoms. It is not known if frequency patterns of constipation symptoms in adults are different between the West and the East. This review aimed to describe core constipation symptoms and their frequency patterns among the Asian adults.

    METHODS: Articles published in PubMed, MEDLINE, CINAHL and Science Direct from 2005 to 2015 were searched systematically. Studies were included if constipation satisfied the Rome II and or III criteria. Study populations consisted of Asian adults above 18 years old and with sample size above 50.

    RESULTS: Of 2812 articles screened, 11 met the eligibility criteria. Constipation among Asian adults was characterized by three core symptoms of 'straining' at 82.8%, 'lumpy and hard stool' at 74.2% and 'sensation of incomplete evacuation' at 68.1% and the least frequent symptom was 'manual maneuver to facilitate defecation' at 23.3%. There was heterogeneity in frequency patterns of core symptoms between different Asian studies but also differences in core symptoms between constipation subtypes of functional constipation and irritable bowel syndrome with constipation.

    CONCLUSIONS: In general, Asian adults perceive constipation symptoms in a similar but not equivalent manner to the West. Recognition of core symptoms will increase the diagnostic confidence of constipation and its subtypes but more studies of the various specific Asian populations are needed to address their differences.

    BACKGROUND: Depression, a type of mental disorder which is portrayed by marked alterations in mood, is associated with distress and/or impaired functioning. Poor social support is an important risk factor for depression in pregnancy. An extensive literature search failed to show any published study conducted in Malaysia on antenatal depressive symptoms and the risk of poor social support on it. The aim of the study was to determine the risk of antenatal depressive symptoms due to poor social support.
    METHODS: This cross sectional study was conducted among 3000 pregnant women attending antenatal clinics in Penang, Malaysia. Edinburgh Postnatal Depression Scale (EPDS) was used to screen for antenatal depressive symptoms and the Oslo-3 Social Support Scale (OSS-3) was used to measure social support. Odds ratio and adjusted odds ratio were used to quantify the risk of antenatal depressive symptoms due to poor social support.
    RESULTS: The prevalence of depressive symptoms was 20%. Using OSS-3 scale to gauge social support, most of the participants had moderate support (61.3%) followed by poor support (22%) and strong support (16.7%). Social support was found to be significantly associated with depressive symptoms in this study (OR 2.2, aOR 2.1, AR 45%).
    CONCLUSIONS: Considering that an expecting mother's psychological factors are important in the wellbeing of the mother and child, antenatal depression must be quickly identified. Screening pregnant women for social support can help identify women with higher risk of depression.
