    Abu Hasan H, Abdullah SR, Kofli NT, Kamarudin SK
    Bioresour Technol, 2012 Nov;124:355-63.
    PMID: 22995166 DOI: 10.1016/j.biortech.2012.08.055
    This study determined the most effective microbes acting as ammonia-oxidising (AOB) and manganese-oxidising bacteria (MnOB) for the simultaneous removal of ammonia (NH(4)(+)-N) and manganese (Mn(2+)) from water. Two conditions of mixed culture of bacteria: an acclimatised mixed culture (mixed culture: MC) in a 5-L bioreactor and biofilm attached on a plastic medium (stages of mixed culture: SMC) in a biological aerated filter were isolated and identified using Biolog MicroSystem and 16S rRNA sequencing. A screening test for determining the most effective microbe in the removal of NH(4)(+)-N and Mn(2+) was initially performed using SMC and MC, respectively, and found that Bacillus cereus was the most effective microbe for the removal of NH(4)(+)-N and Mn(2+). Moreover, the simultaneous NH(4)(+)-N and Mn(2+) removal (above 95% removal for both NH(4)(+)-N and Mn(2+)) was achieved using a biological aerated filter under various operating conditions. Thus, the strain could act as an effective microbe of AOB and a MnOB for the simultaneous removal of NH(4)(+)-N and Mn(2+).

    Islam MR, Abdullah JM, Atoji Y
    Anat Histol Embryol, 2013 Aug;42(4):257-65.
    PMID: 22994540 DOI: 10.1111/ahe.12009
    Bioassay and immunohistochemical studies have detected the presence of prosaposin in the central nervous system (CNS) of mammals. Here, first time, we have determined the partial cDNA sequence of pigeon prosaposin and mapped the distribution of its mRNA in the pigeon CNS. The predicted amino acid sequence of pigeon prosaposin showed 93 and 60% identity to chicken and human prosaposin, respectively. In situ hybridization, autoradiograms showed that the prosaposin mRNA expression was found in the olfactory bulb, prepiriform cortex, Wulst, mesopallium, nidopallium, hippocampal formation, thalamus, tuberis nucleus, pre-tectal nucleus, nucleus mesencephalicus lateralis, pars dorsalis, nucleus isthmi, pars parvocellularis and magnocellularis, Edinger-Westphal nucleus, optic tectum, cerebellar cortex and nuclei, vestibular nuclei and gray matter of the spinal cord. These results suggest that the cDNA sequence of pigeon prosaposin is comparable to other vertebrates, and the general distribution pattern of prosaposin mRNA resembles those are found in mammals.

    The effectiveness of mannose (using phosphomannose isomerase [pmi] gene) as a positive selection agent to preferably allow the growth of transformed oil palm embryogenic calli was successfully evaluated. Using the above selection agent in combination with the previously optimized physical and biological parameters and the best constitutive promoter, oil palm embryogenic calli were transformed with pmi gene for producing transgenic plants. Bombarded embryogenic calli were exposed to embryogenic calli medium containing 30:0 g/L mannose to sucrose 3 weeks postbombardment. Selectively, proliferating embryogenic calli started to emerge around 6 months on the above selection medium. The proliferated embryogenic calli were individually isolated once they reached a specific size and regenerated to produce complete plantlets. The complete regenerated plantlets were evaluated for the presence of transgenes by PCR and Southern analyses.

    Seng TY, Mohamed Saad SH, Chin CW, Ting NC, Harminder Singh RS, Qamaruz Zaman F, et al.
    PLoS One, 2011;6(11):e26593.
    PMID: 22069457 DOI: 10.1371/journal.pone.0026593
    Enroute to mapping QTLs for yield components in oil palm, we constructed the linkage map of a FELDA high yielding oil palm (Elaeis guineensis), hybrid cross. The parents of the mapping population are a Deli dura and a pisifera of Yangambi origin. The cross out-yielded the average by 8-21% in four trials all of which yielded comparably to the best current commercial planting materials. The higher yield derived from a higher fruit oil content. SSR markers in the public domain - from CIRAD and MPOB, as well as some developed in FELDA - were used for the mapping, augmented by locally-designed AFLP markers. The female parent linkage map comprised 317 marker loci and the male parent map 331 loci, both in 16 linkage groups each. The number of markers per group ranged from 8-47 in the former and 12-40 in the latter. The integrated map was 2,247.5 cM long and included 479 markers and 168 anchor points. The number of markers per linkage group was 15-57, the average being 29, and the average map density 4.7 cM. The linkage groups ranged in length from 77.5 cM to 223.7 cM, with an average of 137 cM. The map is currently being validated against a closely related population and also being expanded to include yield related QTLs.

  5. Fulltext Genotype v Japanese encephalitis virus is emerging
    Li MH, Fu SH, Chen WX, Wang HY, Guo YH, Liu QY, et al.
    PLoS Negl Trop Dis, 2011 Jul;5(7):e1231.
    PMID: 21750744 DOI: 10.1371/journal.pntd.0001231
    Japanese encephalitis (JE) is a global public health issue that has spread widely to more than 20 countries in Asia and has extended its geographic range to the south Pacific region including Australia. JE has become the most important cause of viral encephalitis in the world. Japanese encephalitis viruses (JEV) are divided into five genotypes, based on the nucleotide sequence of the envelope (E) gene. The Muar strain, isolated from patient in Malaya in 1952, is the sole example of genotype V JEV. Here, the XZ0934 strain of JEV was isolated from Culex tritaeniorhynchus, collected in China. The complete nucleotide and amino acid sequence of XZ0934 strain have been determined. The nucleotide divergence ranged from 20.3% to 21.4% and amino acid divergence ranged from 8.4% to 10.0% when compared with the 62 known JEV isolates that belong to genotype I-IV. It reveals low similarity between XZ0934 and genotype I-IV JEVs. Phylogenetic analysis using both complete genome and structural gene nucleotide sequences demonstrates that XZ0934 belongs to genotype V. This, in turn, suggests that genotype V JEV is emerging in JEV endemic areas. Thus, increased surveillance and diagnosis of viral encephalitis caused by genotype V JEV is an issue of great concern to nations in which JEV is endemic.

    Al-Shami SA, Rawi CS, Ahmad AH, Nor SA
    Toxicol Ind Health, 2012 Sep;28(8):734-9.
    PMID: 22025505 DOI: 10.1177/0748233711422729
    The genotoxic effects of increasing concentrations (below lethal concentration [LC₅₀]) of cadmium ([Cd] 0.1, 1 and 10 mg/L), copper ([Cu] 0.2, 2 and 20 mg/L) and zinc ([Zn] 0.5, 5 and 50 mg/L) on Chironomus kiiensis were evaluated using alkaline comet assay after exposure for 24 h. Both the tail moment and the olive tail moment showed significant differences between the control and different concentrations of Cd, Cu and Zn (Kruskal-Wallis, p < 0.05). The highest concentration of Cd was associated with higher DNA damage to C. kiiensis larvae compared with Cu and Zn. The potential genotoxicity of these metals to C. kiiensis was Cd > Cu > Zn.

  7. Evolutionary relationship of the L- and M-class genome segments of bat-borne fusogenic orthoreoviruses in Malaysia and Australia
    Voon K, Chua KB, Yu M, Crameri G, Barr JA, Malik Y, et al.
    J Gen Virol, 2011 Dec;92(Pt 12):2930-2936.
    PMID: 21849518 DOI: 10.1099/vir.0.033498-0
    We previously described three new Malaysian orthoreoviruses designated Pulau virus, Melaka virus and Kampar virus. Melaka and Kampar viruses were shown to cause respiratory disease in humans. These viruses, together with Nelson Bay virus, isolated from Australian bats, are tentatively classified as different strains within the species Pteropine orthoreovirus (PRV), formerly known as Nelson Bay orthoreovirus, based on the small (S) genome segments. Here we report the sequences of the large (L) and medium (M) segments, thus completing the whole-genome characterization of the four PRVs. All L and M segments were highly conserved in size and sequence. Conserved functional motifs previously identified in other orthoreovirus gene products were also found in the deduced proteins encoded by the cognate segments of these viruses. Detailed sequence analysis identified two genetic lineages divided into the Australian and Malaysian PRVs, and potential genetic reassortment among the M and S segments of the three Malaysian viruses.

  8. Fulltext Development of conventional and real-time multiplex PCR assays for the detection of nosocomial pathogens
    Anbazhagan D, Mui WS, Mansor M, Yan GO, Yusof MY, Sekaran SD
    Braz J Microbiol, 2011 Apr;42(2):448-58.
    PMID: 24031653 DOI: 10.1590/S1517-83822011000200006
    Nosocomial infections are major clinical threats to hospitalised patients and represent an important source of morbidity and mortality. It is necessary to develop rapid detection assays of nosocomial pathogens for better prognosis and initiation of antimicrobial therapy in patients. In this study, we present the development of molecular methods for the detection of six common nosocomial pathogens including Escherichia coli, Staphylococcus aureus, Streptococcus pneumoniae, Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter spp. Conventional multiplex PCR and SYBR Green based real time PCR assays were performed using genus and species specific primers. Blind testing with 300 clinical samples was also carried out. The two assays were found to be sensitive and specific. Eubacterial PCR assay exhibited positive results for 46 clinical isolates from which 43 samples were detected by real time PCR assay. The sensitivity of the assay is about 93.7% in blind test isolates. The PCR results were reconfirmed using the conventional culture method. This assay has the potential to be a rapid, accurate and highly sensitive molecular diagnostic tool for simultaneous detection of Escherichia coli, Staphylococcus aureus, Streptococcus pneumoniae, Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter spp. This assay has the potential to detect nosocomial pathogens within 5 to 6 hours, helping to initiate infection control measures and appropriate treatment in paediatric and elderly (old aged) patients, pre-and post surgery patients and organ transplant patients and thus reduces their hospitalization duration.

    Saif-Ali R, Muniandy S, Al-Hamodi Z, Lee CS, Ahmed KA, Al-Mekhlafi AM, et al.
    Ann Acad Med Singap, 2011 Nov;40(11):488-92.
    PMID: 22206064
    INTRODUCTION: Type 2 diabetes (T2D) candidate gene: potassium voltage-gated channel, KQT-like subfamily, member 1 (KCNQ1) was suggested by conducting a genome wide association study (GWAS) in Japanese population. Association studies have been replicated among East Asian populations; however, the association between this gene and T2D in Southeast Asian populations still needs to be studied. This study aimed to investigate the association of KCNQ1 common variants with type 2 diabetes in Malaysian Malay subjects.

    MATERIALS AND METHODS: The KCNQ1 single nucleotide polymorphisms (SNPs): rs2237892, rs2283228, and rs2237895 were genotyped in 234 T2D and 177 normal Malay subjects.

    RESULTS: The risk allele of the rs2283228 (A) was strongly associated with T2D (OR = 1.7, P = 0.0006) while the rs2237892 (C) was moderately associated with T2D (OR = 1.45, P = 0.017). The recessive genetic models showed that rs2283228 was strongly associated with T2D (OR = 2.35, P = 0.00005) whereas rs2237892 showed a moderate association with T2D (OR = 1.69, P = 0.01). The haplotype block (TCA), which contained the protective allele, correlated with a protection from T2D (OR = 0.5, P = 0.003). Furthermore, the diplotype (CAA-TCA) that contained the protective haplotype was protected against T2D (OR = 0.46, P = 0.006).

    CONCLUSION: The KCNQ1 SNPs, haplotypes and diplotypes are associated with T2D in the Malaysian Malay subjects.

  10. Multilocus analysis of the evolutionary dynamics of rainforest bird populations in Southeast Asia
    Lim HC, Sheldon FH
    Mol Ecol, 2011 Aug;20(16):3414-38.
    PMID: 21777318 DOI: 10.1111/j.1365-294X.2011.05190.x
    Sundaland has a dynamic geographic history because its landmasses were periodically interconnected when sea levels fell during glacial periods. Superimposed on this geographic dynamism were environmental changes related to climatic oscillations. To investigate how tropical taxa responded to such changes, we studied the divergence and demographic history of two co-distributed rainforest passerine species, Arachnothera longirostra and Malacocincla malaccensis. We sampled birds primarily from Borneo and the Malay Peninsula, which straddle the now-submerged Sunda shelf, and analysed multilocus DNA data with a variety of coalescent and gene genealogy methods. Cross-shelf divergence in both species occurred well before the last glacial maximum, i.e., before the most recent land connection. However, post-divergence gene flow occurred, and it was more pronounced in A. longirostra (a highly vagile nectarivore/insectivore) than in M. malaccensis (an understory insectivore). Despite current habitat continuity on Borneo, the population of M. malaccensis in northeastern Borneo is substantially divergent from that on the rest of the island. The NE population experienced dramatic demographic fluctuations, probably because of competition with the other population, which expanded from western Borneo after the mid-Pleistocene. In contrast, the Borneo population of A. longirostra has little structure and appears to have experienced demographic expansion 16 kya, long after it had diverged from the Malay Peninsula population (630-690 kya). Malay Peninsula populations of both species have remained relatively stable. Overall, the most recent glacial period was not the chief determinant of the evolutionary dynamics of our study species, and in this respect, they are different from temperate species.

  11. Tridimensional personalities and polymorphism of dopamine D2 receptor among heroin addicts
    Teh LK, Izuddin AF, M H FH, Zakaria ZA, Salleh MZ
    Biol Res Nurs, 2012 Apr;14(2):188-96.
    PMID: 21613340 DOI: 10.1177/1099800411405030
    Drug addiction is a multifactorial disorder. Researchers have posited that an individual's inherited behavioral propensity or temperament contributes to the disorder by shaping a personality strongly linked with the risk of drug abuse. Further, they hypothesize that the polymorphism of dopamine D2 receptor increases the susceptibility to and severity of addiction. We, therefore, investigated possible associations between dopamine D2 receptor (DRD2) and personality traits among intravenous heroin addicts.

  13. Fulltext First case of detection of Plasmodium knowlesi in Spain by Real Time PCR in a traveller from Southeast Asia
    Ta TT, Salas A, Ali-Tammam M, Martínez Mdel C, Lanza M, Arroyo E, et al.
    Malar J, 2010;9:219.
    PMID: 20663184 DOI: 10.1186/1475-2875-9-219
    Previously, Plasmodium knowlesi was not considered as a species of Plasmodium that could cause malaria in human beings, as it is parasite of long-tailed (Macaca fascicularis) and pig-tailed (Macaca nemestrina) macaques found in Southeast Asia. A case of infection by P. knowlesi is described in a Spanish traveller, who came back to Spain with daily fever after his last overseas travel, which was a six-month holiday in forested areas of Southeast Asia between 2008 and 2009. His P. knowlesi infection was detected by multiplex Real time quantitative PCR and confirmed by sequencing the amplified fragment. Using nested multiplex malaria PCR (reference method in Spain) and a rapid diagnostic test, the P. knowlesi infection was negative. This patient was discharged and asymptomatic when the positive result to P. knowlesi was reported. Prior to this case, there have been two more reports of European travellers with malaria caused by P. knowlesi, a Finnish man who travelled to Peninsular Malaysia during four weeks in March 2007, and a Swedish man who did a short visit to Malaysian Borneo in October 2006. Taken together with this report of P. knowlesi infection in a Spanish traveller returning from Southeast Asia, this is the third case of P. knowlesi infection in Europe, indicating that this simian parasite can infect visitors to endemic areas in Southeast Asia. This last European case is quite surprising, given that it is an untreated-symptomatic P. knowlesi in human, in contrast to what is currently known about P. knowlesi infection. Most previous reports of human P. knowlesi malaria infections were in adults, often with symptoms and relatively high parasite densities, up to the recent report in Ninh Thuan province, located in the southern part of central Vietnam, inhabited mainly by the Ra-glai ethnic minority, in which all P. knowlesi infections were asymptomatic, co-infected with P. malariae, with low parasite densities and two of the three identified cases were very young children under five years old.

    There are at least 51 adenovirus serotypes (AdV) known to cause human infections. The prevalence of the different human AdV (HAdV) serotypes varies among different regions. Presently, there are no reports of the prevalent HAdV types found in Malaysia. The present study was undertaken to identify the HAdV types associated primarily with respiratory tract infections (RTI) of young children in Malaysia.

  17. Cloning of triose phosphate isomerase gene from an antarctic psychrophilic Pseudomonas sp. by degenerate and splinkerette PCR

    World J Microbiol Biotechnol, 2010 Jul;26(7):1251-9.

    Psychrophiles are organisms that thrive in cold environments. One of the strategies for their cold adaptation is the ability to synthesize cold-adapted enzymes. These enzymes usually display higher catalytic efficiency and thermolability at lower temperatures compared to their mesophilic and thermophilic counterparts. In this work, a psychrophilic bacterial isolate codenamed π9 was selected for the cloning of the gene encoding triose phosphate isomerase (TIM), an enzyme in the glycolytic pathway. Based on 16S rRNA gene sequence analysis, this isolate was identified as a species of the genus Pseudomonas under the P. fluorescens group. The cloning of a 816 bp fragment of TIM gene which covers the 756 bp open reading frame was achieved by a combination of degenerate and splinkerette PCRs. The partial sequence of this gene was first PCR amplified by using degenerate primers and the flanking sequences were subsequently amplified by splinkerette PCR technique. Amino acid sequence of the cloned TIM was 97% identical to TIM from Pseudomonas fluorescens and shared 51% identity with the TIM from psychrophilic Vibrio sp. This work demonstrated the use of multiple PCR techniques to clone a gene without prior knowledge of its sequence. The cloning of the TIM gene by PCR was more rapid and cost effective compared to the traditional genomic library construction and screening method. Homology model of the TIM protein in this study was generated based on Escherichia coli TIM crystal structure. The model could serve as a hypothetical TIM structure from a psychrophilic microorganism for further investigation into areas that showed deviations from the known mesophilic TIM structures.

  18. Fulltext Plasmodium knowlesi malaria in Vietnam: some clarifications

    Malar J, 2010;9:20.
    PMID: 20082717 DOI: 10.1186/1475-2875-9-20
    A recently published comment on a report of Plasmodium knowlesi infections in Vietnam states that this may not accurately represent the situation in the study area because the PCR primers used may cross-hybridize with Plasmodium vivax. Nevertheless, P. knowlesi infections have been confirmed by sequencing. In addition, a neighbour-joining tree based on the 18S S-Type SSUrRNA gene shows that the Vietnamese samples clearly cluster with the P. knowlesi isolates identified in Malaysia and are distinct from the corresponding P. vivax sequences. All samples came from asymptomatic individuals who did not consult for fever during the months preceding or following the survey, indicating that asymptomatic P. knowlesi infections occur in this population, although this does not exclude the occurrence of symptomatic cases. Large-scale studies to determine the extent and the epidemiology of P. knowlesi malaria in Vietnam are further needed.

  20. Fulltext Isolation and characterization of a replication-competent molecular clone of an HIV-1 circulating recombinant form (CRF33_01B)
    Tee KK, Kusagawa S, Li XJ, Onogi N, Isogai M, Hase S, et al.
    PLoS One, 2009;4(8):e6666.
    PMID: 19688091 DOI: 10.1371/journal.pone.0006666
    A growing number of emerging HIV-1 recombinants classified as circulating recombinant forms (CRFs) have been identified in Southeast Asia in recent years, establishing a molecular diversity of increasing complexity in the region. Here, we constructed a replication-competent HIV-1 clone for CRF33_01B (designated p05MYKL045.1), a newly identified recombinant comprised of CRF01_AE and subtype B. p05MYKL045.1 was reconstituted by cloning of the near full-length HIV-1 sequence from a newly-diagnosed individual presumably infected heterosexually in Kuala Lumpur, Malaysia. The chimeric clone, which contains the 5' LTR (long terminal repeat) region of p93JP-NH1 (a previously isolated CRF01_AE infectious clone), showed robust viral replication in the human peripheral blood mononuclear cells. This clone demonstrated robust viral propagation and profound syncytium formation in CD4+, CXCR4-expressing human glioma NP-2 cells, indicating that p05MYKL045.1 is a CXCR4-using virus. Viral propagation, however, was not detected in various human T cell lines including MT-2, M8166, Sup-T1, H9, Jurkat, Molt-4 and PM1. p05MYKL045.1 appears to proliferate only in restricted host range, suggesting that unknown viral and/or cellular host factors may play a role in viral infectivity and replication in human T cell lines. Availability of a CRF33_01B molecular clone will be useful in facilitating the development of vaccine candidates that match the HIV-1 strains circulating in Southeast Asia.
