    PMID: 10827955
    A paramyxovirus virus termed Nipah virus has been identified as the etiologic agent of an outbreak of severe encephalitis in people with close contact exposure to pigs in Malaysia and Singapore. The outbreak was first noted in late September 1998 and by mid-June 1999, more than 265 encephalitis cases, including 105 deaths, had been reported in Malaysia, and 11 cases of encephalitis or respiratory illness with one death had been reported in Singapore. Electron microscopic, serologic, and genetic studies indicate that this virus belongs to the family Paramyxoviridae and is most closely related to the recently discovered Hendra virus. We suggest that these two viruses are representative of a new genus within the family Paramyxoviridae. Like Hendra virus, Nipah virus is unusual among the paramyxoviruses in its ability to infect and cause potentially fatal disease in a number of host species, including humans.

    Lim PE, Kiu MY
    Environ Monit Assess, 1995 Apr;35(2):85-95.
    PMID: 24202270 DOI: 10.1007/BF00633708
    The Juru River flows through largely urbanized areas and is grossly polluted by domestic wastes and discharges from pig farms. Other than carrying highly polluting organic materials, these wastes are also contaminated with heavy metals. To ascertain the extent of heavy metal pollution in the river, total and non-residual concentrations of Cu, Pb, Zn, Mn and Fe in sediment samples collected along the river were determined. The results indicate that both the total and non-residual metal concentrations in sediments can successfully be used to identify heavy metal pollution sources. The speciation of Zn, Mn and Fe in the sediment samples were investigated using a sequential leaching technique which identifies the elements among six operationally defined host fractions: (1) exchangeable, (2) carbonate and surface-associated, (3) easily reducible, (4) moderately reducible, (5) bound to organic matter and sulphides and (6) residual. The results indicate that Zn is mainly associated with the reducible fractions. Zn and Fe found in the moderately reducible fraction are significantly correlated, indicating that iron oxides is the preferred host phase by Zn.

    Sg. Papar is one of the rivers in Kota Kinabalu which is mainly used for water supply especially in Papar district. For the past years, many pollution cases concerning Sg. Papar have been reported which originated from various sources including pig farm, agricultural run-off and deforestation. These resulted in a frequent shutdown of the water treatment plants in Papar district leading to water supply disturbance and water supply deficiency in the affected area. The data utilized in this study were obtained from water quality tests performed on river water samples taken from Limbahau water treatment plant recorded from September 2013 to September 2016. Principal Component Analysis (PCA) was used in this study to analyze and correlate the physicochemical parameters with the water treatment plant shutdown. The results revealed that eight parameters (pH, alum, nitrate, TDS, DO, conductivity, colour and chloride) analysed in this study correlate with each other and the parameter that mostly caused the drastic change in the river water and as pollution index is turbidity. This study is critical for understanding the relationship between the water quality paramters and environmental issues.

    MyJurnal
    Introduction: Adenoviruses are important in public health. They are used as indicators for microbial pollution source tracking (MST), and as vaccine vectors. Knowledge of host specificity and pre-existing immunity are critical for the two applications. Bovine and porcine adenoviruses are expected to be widespread in the environment through agriculture. Here we examined if bovine and porcine adenovirus strains are truly distinctive from other adenovirus strains. Methods: 46 adenovirus strains with complete genome were downloaded from the RefSeq database of Gen-Bank. 450 bp of nucleotides each at positions 1- 450, 18001-18450, and 27001 – 27450 of the respective strains were subjected to the Disparity Index Test using Mega 7 software. Analysis focused on four adenovirus strains: Bo-vine B, Bovine D, Porcine C and Porcine 3. The total number of strains that were significantly different (P

  7. Fulltext The employment of q-PCR using specific primer targeting on mitochondrial cytochrome-b gene for identification of wild boar meat in meatball samples
    Aina GQ, Erwanto Y, Hossain M, Johan MR, Ali ME, Rohman A
    J Adv Vet Anim Res, 2019 Sep;6(3):300-307.
    PMID: 31583226 DOI: 10.5455/javar.2019.f348
    Objective: The objective of this study was to employ real-time or quantitative polymerase chain reaction (q-PCR) using novel species specific primer (SSP) targeting on mitochondrial cytochrome-b of wild boar species (CYTBWB2-wb) gene for the identification of non-halal meat of wild boar meat (WBM) in meatball products.

    Materials and Methods: The novel SSP of CYTBWB2-wb was designed by our group using PRIMERQUEST and NCBI software. DNA was extracted using propanol-chloroform-isoamyl alcohol method. The designed SSP was further subjected for validation protocols using DNA isolated from fresh meat and from meatball, which include specificity test, determination of efficiency, limit of detection and repeatability, and application of developed method for analysis of commercially meatball samples.

    Results: The results showed that CYTBWB2-wb was specific to wild boar species against other animal species with optimized annealing temperature of 59°C. The efficiency of q-PCR obtained was 91.9% which is acceptable according to the Codex Allimentarius Commission (2010). DNA, with as low as 5 pg/μl, could be detected using q-PCR with primer of CYTBWB2-wb. The developed method was also used for DNA analysis extracted from meatball samples commercially available.

    Conclusion: q-PCR using CYTBWB2-wb primers targeting on mitochondrial cytochrome-b gene (forward: CGG TTC CCT CTT AGG CAT TT; Reverse: GGA TGA ACA GGC AGA TGA AGA) can be fruitfully used for the analysis of WBM in commercial meatball samples.

    Nakyinsige K, Man YB, Sazili AQ
    Meat Sci, 2012 Jul;91(3):207-14.
    PMID: 22405913 DOI: 10.1016/j.meatsci.2012.02.015
    In the recent years, Muslims have become increasingly concerned about the meat they eat. Proper product description is very crucial for consumers to make informed choices and to ensure fair trade, particularly in the ever growing halal food market. Globally, Muslim consumers are concerned about a number of issues concerning meat and meat products such as pork substitution, undeclared blood plasma, use of prohibited ingredients, pork intestine casings and non-halal methods of slaughter. Analytical techniques which are appropriate and specific have been developed to deal with particular issues. The most suitable technique for any particular sample is often determined by the nature of the sample itself. This paper sets out to identify what makes meat halal, highlight the halal authenticity issues that occur in meat and meat products and provide an overview of the possible analytical methods for halal authentication of meat and meat products.

    Aida AA, Che Man YB, Wong CM, Raha AR, Son R
    Meat Sci, 2005 Jan;69(1):47-52.
    PMID: 22062638 DOI: 10.1016/j.meatsci.2004.06.020
    A method for species identification from pork and lard samples using polymerase chain reaction (PCR) analysis of a conserved region in the mitochondrial (mt) cytochrome b (cyt b) gene has been developed. Genomic DNA of pork and lard were extracted using Qiagen DNeasy(®) Tissue Kits and subjected to PCR amplification targeting the mt cyt b gene. The genomic DNA from lard was found to be of good quality and produced clear PCR products on the amplification of the mt cyt b gene of approximately 360 base pairs. To distinguish between species, the amplified PCR products were cut with restriction enzyme BsaJI resulting in porcine-specific restriction fragment length polymorphisms (RFLP). The cyt b PCR-RFLP species identification assay yielded excellent results for identification of pig species. It is a potentially reliable technique for detection of pig meat and fat from other animals for Halal authentication.

  10. Blood-Brain Barrier Permeability of Asiaticoside, Madecassoside and Asiatic Acid in Porcine Brain Endothelial Cell Model
    Hanapi NA, Mohamad Arshad AS, Abdullah JM, Tengku Muhammad TS, Yusof SR
    J Pharm Sci, 2021 02;110(2):698-706.
    PMID: 32949562 DOI: 10.1016/j.xphs.2020.09.015
    Neurotherapeutic potentials of Centella asiatica and its reputation to boost memory, prevent cognitive deficits and improve brain functions are widely acknowledged. The plant's bioactive compounds, i.e. asiaticoside, madecassoside and asiatic acid were reported to have central nervous system (CNS) actions, particularly in protecting the brain against neurodegenerative disorders. Hence, it is important for these compounds to cross the blood-brain barrier (BBB) to be clinically effective therapeutics. This study aimed to explore the capability of asiaticoside, madecassoside and asiatic acid to cross the BBB using in vitro BBB model from primary porcine brain endothelial cells (PBECs). Our findings showed that asiaticoside, madecassoside and asiatic acid are highly BBB permeable with apparent permeability (Papp) of 70.61 ± 6.60, 53.31 ± 12.55 and 50.94 ± 10.91 × 10-6 cm/s respectively. No evidence of cytotoxicity and tight junction disruption of the PBECs were observed in the presence of these compounds. Asiatic acid showed cytoprotective effect towards the PBECs against oxidative stress. This study reported for the first time that Centella asiatica compounds demonstrated high capability to cross the BBB, comparable to central nervous system drugs, and therefore warrant further development as therapeutics for the treatment of neurodegenerative diseases.

  11. Inhibitory effect of the extract from Sonchus olearleu on the formation of carcinogenic heterocyclic aromatic amines during the pork cooking
    Teng H, Chen Y, Lin X, Lv Q, Chai TT, Wong FC, et al.
    Food Chem Toxicol, 2019 Jul;129:138-143.
    PMID: 31034934 DOI: 10.1016/j.fct.2019.04.043
    The aim of this study was to assess the inhibitory effects of Sonchus olearleu extract on the generation of heterocyclic amines in roasted pork patties cooked by pan-frying. All samples were cooked for two different durations (45 min and 105 min) under 200 °C and 230 °C. 2-amino-3-methylimidazo[4,5-f]quinoline (IQ), 2-ami- no-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx), 2-amino-3,4,8-trimethylimidazo[4,5-f]quinox-aline (4,8-DiMeIQx), harman, and norharman were detected and quantified. In patties cooked at 230 °C for 105 min, S. olearleu extract (0.5%) significantly inhibited the formation of IQ, harman, and norharman by 39%, 67%, and 63%, respectively. In contrast to IQ, the levels of harman and norharman were significantly reduced by the extracts tested. However, no such effects were observed for MeIQx and 4, 8-DiMeIQx. Notably, the inhibitory effect on heterocyclic amines is significantly correlated with the antioxidant potential and total phenolic content of S. olearleu extract.

    Goh CF, Moffat JG, Craig DQM, Hadgraft J, Lane ME
    Mol Pharm, 2019 01 07;16(1):359-370.
    PMID: 30525649 DOI: 10.1021/acs.molpharmaceut.8b01027
    Drug crystallization on and in the skin has been reported following application of topical or transdermal formulations. This study explored novel probe-based approaches including localized nanothermal analysis (nano-TA) and photothermal microspectroscopy (PTMS) to investigate and locate drug crystals in the stratum corneum (SC) of porcine skin following application of simple ibuprofen (IBU) formulations. We also conducted in vitro skin permeation studies and tape stripping. The detection of drug crystals in the SC on tape strips was confirmed using localized nano-TA, based on the melting temperature of IBU. The melting of IBU was also evident as indicated by a double transition and confirmed the presence of drug crystals in the SC. The single point scans of PTMS on the tape strips allowed collection of the photothermal FTIR spectra of IBU, confirming the existence of drug crystals in the skin. The combined methods also indicated that drug crystallized in the SC at a depth of ∼4-7 μm. Future studies will examine the potential of these techniques to probe crystallization of other commonly used actives in topical and transdermal formulations.

  13. Fulltext Evolution of Nipah Virus Infection: Past, Present, and Future Considerations
    Hauser N, Gushiken AC, Narayanan S, Kottilil S, Chua JV
    Trop Med Infect Dis, 2021 Feb 14;6(1).
    PMID: 33672796 DOI: 10.3390/tropicalmed6010024
    Nipah virus (NiV) is a zoonotic paramyxovirus of the Henipavirus genus first identified in Malaysia in 1998. Henipaviruses have bat reservoir hosts and have been isolated from fruit bats found across Oceania, Asia, and Africa. Bat-to-human transmission is thought to be the primary mode of human NiV infection, although multiple intermediate hosts are described. Human infections with NiV were originally described as a syndrome of fever and rapid neurological decline following contact with swine. More recent outbreaks describe a syndrome with prominent respiratory symptoms and human-to-human transmission. Nearly annual outbreaks have been described since 1998 with case fatality rates reaching greater than 90%. The ubiquitous nature of the reservoir host, increasing deforestation, multiple mode of transmission, high case fatality rate, and lack of effective therapy or vaccines make NiV's pandemic potential increasingly significant. Here we review the epidemiology and microbiology of NiV as well as the therapeutic agents and vaccines in development.

  14. Fulltext In Vitro Performance of Dutasteride-Nanostructured Lipid Carriers Coated with Lauric Acid-Chitosan Oligomer for Dermal Delivery
    Noor NM, Abdul-Aziz A, Sheikh K, Somavarapu S, Taylor KMG
    Pharmaceutics, 2020 Oct 20;12(10).
    PMID: 33092119 DOI: 10.3390/pharmaceutics12100994
    Dutasteride, licensed as an oral medicine for the treatment of benign prostatic hypoplasia, has been investigated as a treatment for androgenic alopecia. In this study, the potential for dustasteride to be delivered topically in order to reduce systemic exposure, irritation of the skin, and also cytotoxicity was explored. Chitosan oligomer (CSO) was successfully synthesised with lauric acid as a coating for a dutasteride-loaded nanostructured lipid carriers (DST-NLCs) system. DST-NLCs were prepared using a combination of melt-dispersion and ultrasonication. These negatively charged NLCs (-18.0 mV) had a mean particle size of ~184 nm, which was not significantly increased (p > 0.05) when coated with lauric acid-chitosan oligomer (CSO-LA), whilst the surface charge changed to positive (+24.8 mV). The entrapment efficiency of DST-NLCs was 97%, and coated and uncoated preparations were physically stable for up to 180 days at 4-8 °C. The drug release was slower from DST-NLCs coated with CSO-LA than from uncoated NLCs, with no detectable drug permeation through full-thickness pig ear skin from either preparation. Considering the cytotoxicity, the IC50 values for the DST-NLCs, coated and uncoated with CSO-LA were greater than for dutasteride alone (p < 0.05). DST-NLCs and empty NLCs coated with CSO-LA at 25 µM increased the cell proliferation compared to the control, and no skin irritation was observed when the DST-NLC formulations were tested using EpiDerm™. The cell and skin uptake studies of coated and uncoated NLCs incorporating the fluorescent marker Coumarin-6 showed the time-dependent uptake of Coumarin-6. Overall, the findings suggest that DST-NLCs coated with CSO-LA represent a promising formulation strategy for dutasteride delivery for the treatment of androgenic alopecia, with a reduced cytotoxicity compared to that of the drug alone and lower irritancy than an ethanolic solution of dutasteride.

  15. Fulltext Vaccine Development for Nipah Virus Infection in Pigs
    McLean RK, Graham SP
    Front Vet Sci, 2019;6:16.
    PMID: 30778392 DOI: 10.3389/fvets.2019.00016
    Nipah virus (NiV) causes a severe and often fatal neurological disease in humans. Whilst fruit bats are considered the natural reservoir, NiV also infects pigs and may cause an unapparent or mild disease. Direct pig-to-human transmission was responsible for the first and still most devastating NiV outbreaks in Malaysia and Singapore in 1998-99, with nearly 300 human cases and over 100 fatalities. Pigs can therefore play a key role in the epidemiology of NiV by acting as an "amplifying" host. The outbreak in Singapore ended with the prohibition of pig imports from Malaysia and the Malaysian outbreak was ended by culling 45% of the country's pig population with costs exceeding US$500 million. Despite the importance of NiV as an emerging disease with the potential for pandemic, no vaccines, or therapeutics are currently approved for human or livestock use. In this mini-review, we will discuss current knowledge of NiV infection in pigs; our ongoing work to develop a NiV vaccine for use in pigs; and the pig as a model to support human vaccine development.

  16. Fulltext Species-specific identification of porcine blood plasma in heat-treated chicken meatballs
    Shahimi S, Abd Mutalib S, Ismail N, Elias A, Hashim H, Kashim MIAM
    Saudi J Biol Sci, 2021 Apr;28(4):2447-2452.
    PMID: 33911957 DOI: 10.1016/j.sjbs.2021.01.043
    This study was conducted to detect the presence of chicken and porcine DNA in meatballs using mitochondria DNA (mtDNA) of cytochrome b (cyt b) and nuclear DNA (nDNA) short interspersed nuclear element (SINE) species-specific primers, respectively. While, the mtDNA primers targeted transfer RNA-ATP8 (tRNA-ATP8) gene was used for 1 and 5% (w/w) chicken meatball spiked with commercial porcine blood plasm. Chicken meatballs spiked with 1% and 5% (v/w) fresh and commercial porcine blood plasma, respectively were prepared and heat-treated using five (n = 5) cooking methods: boiling, pan-frying, roasting, microwaving and autoclaving. Two pairs of mtDNA and nDNA primers used, produced 129 and 161 bp amplicons, respectively. Whereas, tRNA-ATP8 primers produced 212 bp of amplicon. Electrophoresis analysis showed positive results for porcine DNA at 1% and 5% (w/w or v/v) for all of the different cooking techniques, either for fresh or commercial blood plasma using SINE primers but not for tRNA-ATP8 primers. The present study has highlighted the useful of species-specific primers of SINE primers in PCR analysis for detecting porcine DNA blood plasma in heat-treated chicken meatballs.

  17. Molecular mechanisms underlying lignocellulose degradation and antibiotic resistance genes removal revealed via metagenomics analysis during different agricultural wastes composting
    Ma C, Lo PK, Xu J, Li M, Jiang Z, Li G, et al.
    Bioresour Technol, 2020 Oct;314:123731.
    PMID: 32615447 DOI: 10.1016/j.biortech.2020.123731
    In this study, the differences on the physico-chemical parameters, lignocellulose degradation, dynamic succession of microbial community, gene expression of carbohydrate-active enzymes and antibiotics resistance genes were compared during composting systems of bagasse pith/pig manure (BP) and manioc waste/pig manure (MW). The results revealed that biodegradation rates of organic matter, cellulose, hemicellulose and lignin (29.14%, 17.53%,45.36% and 36.48%) in BP were higher than those (15.59%, 16.74%, 41.23% and 29.77%) in MW. In addition, the relative abundance of Bacillus, Luteimonas, Clostridium, Pseudomonas, Streptomyces and expression of genes encoding carbohydrate- active enzymes in BP were higher than those in MW based on metagenomics sequencing. During composting, antibiotics and antibiotic resistance genes were substantially reduced, but the removal efficiency was divergent in the both samples. Taken together, metagenomics analysis was a potential method for evaluating lignocellulose's biodegradation process and determining the elimination of antibiotic and antibiotic resistance genes from different composting sources of biomass.

  18. Hydroxyproline determination for initial detection of halal-critical food ingredients (gelatin and collagen)
    Yuswan MH, A Jalil NH, Mohamad H, Keso S, Mohamad NA, Tengku Md Yusoff TS, et al.
    Food Chem, 2021 Feb 01;337:127762.
    PMID: 32777563 DOI: 10.1016/j.foodchem.2020.127762
    Gelatin and collagen are considered halal-critical ingredients as they are typically derived from either bovine or porcine animals. Current analytical methods for determining the sources of gelatin and collagen suffer from limitations in terms of robustness and false positives in peptide matching. Thus, the aim of this study was to investigate the utility of monitoring hydroxyproline, a signature amino acid for gelatin and collagen, for identifying potentially haram foodstuffs. To determine the hydroxyproline profiles among animal- and plant-based samples, one-way univariate analysis of variance followed by pair-wise comparison was used to establish statistical significance. Multivariate chemometric analysis through principal component analysis revealed a discrete distribution pattern among 59 samples due to hydroxyproline variability. Finally, inter- and intra-laboratory comparisons demonstrated the validity and robustness of hydroxyproline determination according to ISO 17025. Thus, this preliminary identification technique will aid the identification of potentially haram foodstuffs.

  19. Fulltext Seasonal Filarial Infections and Their Black Fly Vectors in Chiang Mai Province, Northern Thailand
    Aupalee K, Saeung A, Srisuka W, Fukuda M, Streit A, Takaoka H
    Pathogens, 2020 Jun 25;9(6).
    PMID: 32630410 DOI: 10.3390/pathogens9060512
    The transmission of zoonotic filarial parasites by black flies has so far been reported in the Chiang Mai and Tak provinces, Thailand, and the bites of these infected black flies can cause a rare disease-human zoonotic onchocerciasis. However, species identification of the filarial parasites and their black fly vectors in the Chiang Mai province were previously only based on a morphotaxonomic analysis. In this study, a combined approach of morphotaxonomic and molecular analyses (mitochondrial cox1, 12S rRNA, and nuclear 18S rRNA (SSU HVR-I) genes) was used to clarify the natural filarial infections in female black flies collected by using human and swine baits from two study areas (Ban Lek and Ban Pang Dang) in the Chiang Mai province from March 2018 to January 2019. A total of 805 and 4597 adult females, belonging to seven and nine black fly taxa, were collected from Ban Lek and Ban Pang Dang, respectively. At Ban Lek, four of the 309 adult females of Simulium nigrogilvum were positive for Onchocerca species type I in the hot and rainy seasons. At Ban Pang Dang, five unknown filarial larvae (belonging to the same new species) were detected in Simulium sp. in the S. varicorne species-group and in three species in the S. asakoae species-group in all seasons, and three non-filarial larvae of three different taxa were also found in three females of the S. asakoae species-group. This study is the first to molecularly identify new filarial species and their vector black fly species in Thailand.

    Ibrahim M, Abdul Azziz SSS, Wong CF, Bakri YM, Abdullah F
    Curr Comput Aided Drug Des, 2020;16(6):698-706.
    PMID: 31648647 DOI: 10.2174/1573409915666191015112320
    BACKGROUND: Obesity is one serious health condition that contributes to various chronic diseases. The inhibition of pancreatic lipase is a promising treatment for obesity.

    OBJECTIVE: The present study was designed to investigate anti-porcine pancreatic lipase effect of isolated compounds from Aquilaria subintegra and its mechanism.

    METHODS: Compounds were isolated with serial column chromatography and their structure were identified using spectroscopic methods. Isolated compounds were tested for anti-lipase potential activity using colorimetric assay. The prediction of energy binding between isolated compounds and enzyme was described using YASARA software.

    RESULTS: Four compounds were successfully isolated from the bark of A. subintegra, namely, 5- hydroxy-7,4'-dimethoxyflavone, luteolin-7,3',4'-trimethyl ether, 5,3'-dihydroxy-7,4'-dimethoxyflavone and β-sitosterol. The results indicated that all compounds displayed promising pancreatic lipase inhibitory activity ranging between of 6% to 53% inhibition. Compound 5-hydroxy-7,4'- dimethoxyflavone was a competitive inhibitor and decreases the enzyme catalysis. Meanwhile, β- sitosterol was a non- competitive inhibitor since the latter was bind allosterically toward enzyme.

    CONCLUSION: This finding is significant for further investigation of bioactive compounds from A. subintegra on animal study.
