  1. The nutritional value of indigenous fruits and vegetables in Sarawak
    Hoe VB, Siong KH
    Asia Pac J Clin Nutr, 1999 Mar;8(1):24-31.
    PMID: 24393732
    The proximate composition including mineral and vitamin contents of 16 fruits and 46 vegetables (leaves, fruits, palm hearts and shoots) of indigenous origin in Sarawak are provided. Fruits like dabai (Canarium odontophyllum), kembayau (Dacryodes rostrata f. cuspidata), durian nyekak (Durio kutejensis) and durian kuning (Durio graveolens) are very nutritious with high values for energy, protein and potassium. Among the vegetables, the protein content of letup (Passiflora foetida), kepayang (Pangium edule) and tubu (Pycnarrhena tumetacta) is high, ranging from 6 to 7%. The range of nutrients among foods of indigenous origin are generally comparable with those of many cultivated species except for vitamin C, which is lower. Teh Kampung (Leucosyke capitellata) leaves are particularly high in magnesium (626 mg/100 g). Some of the indigenous vegetables contain antinutritional factors. Kepayang has very high levels of hydrogen cyanide (1834 µg/g on dry basis) but this poison can be completely evaporated by boiling. Indigenous fruits and vegetables which are pesticide residue free are important food sources for rural populations. Nutritious indigenous fruits and vegetables have the potential to be promoted for wider use, domestication and commercialization.

    PMID: 24575183 MyJurnal
    Hibiscus rosa sinensis, a member of the Malvaceae family, is widely cultivated in the tropics as an ornamental plant. It is often planted as a fence or hedge plant, and has several forms of flowers with varying colours. It is also used in traditional medicine to induce abortion, ease menstrual cramps, assist in childbirth and relieve headache, fever and inflammation. In this study, we evaluated the antibacterial activity of H. rosa sinesis extract using a disc diffusion method. Crude petroleum ether extract, ethyl acetate extract and methanol extract from the leaves, stems and flowers of the plant were prepared using a cold extraction technique. These extracts were tested at concentrations ranging from 4 mg/disc to 0.017 mg/disc against methicillin-resistant Staphylococcus aureus (MRSA), Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumonia. The petroleum ether extract from the leaves, stems and flowers and methanol extract from the leaves showed inhibition zones with diameters > 12 mm against MRSA. Overall, the petroleum ether extract from flowers at concentrations of 4 mg/disc and 2 mg/disc displayed the strongest inhibition zones of 18.6 ± 2.85 mm and 18.5 ± 0.29 mm, respectively, as compared to vancomycin (30 μg/ml), which did not differ significantly from the 18.0 ± 0.10 mm size of the vancomycin (30 μg/ml) inhibition zone (p < 0.05). In conclusion, H. rosa sinensis extract is a potential antibacterial agent for treating MRSA infection.

    MyJurnal
    Kaum wanita sebagai figura dunia merupakan satu pengikitirafan dan penghormatan tertinggi bagi mereka. Beberapa ‘figura’ wanita dunia dijadikan sebagai unit analisis untuk mengkategorikan gaya komunikasi yang diaplikasi dalam melaksanakan tanggungjawab sebagai ketua kerajaan dan juga sebagai idola masyarakat dunia.Salah satu ciri untuk menjadi figura dan pemimpin yang berkesan adalah dengan mengamalkan gaya komunikasi yang difikirkan sesuai berdasarkan persoalan tentang Siapa, Di mana dan Bagaimana gaya komunikasi tersebut diaplikasikan. Gaya komunikasi merupakan satu wadahyang digunakan bukan sahaja untuk memastikan kelancaran perjalanan pengurusan sesebuah organisasi namun juga penting dalam urusan hal ehwal tadbir melibatkan kerajaan sesebuah negara serta ketika berhadapan dengan khalayak. “The way you lead is thru the way you speak” merupakan falsafah budaya kepemimpinan yang menjadi asas kepada kertas kerja ini. Konsep kertas kerja ini adalah berpaksikan kepada enam gaya komunikasi oleh Tubbs dan Moss (2008) dengan menggunakan kaedah analisis dokumen. Kertas kerja ini juga akan memberikan pemahaman yang lebih jelas tentang gaya komunikasi yang diamalkan oleh ‘figura’wanita dunia dalam melaksanakan praktis pengurusan dan pentadbiran kerajaan, organisasi yang diwakili mahupun sewaktu mereke perlu berhadapan dengan publik. Kertas kerja ini diharapkan mampu untuk menjadi perintis agar satu kajian yang lebih mendalam berkaitan karisma wanita samaada sebagai ketua kerajaan mahupun “public figure”daripada aspek komunikasi dapat dilakukan pada masa akan datang

    Trop Biomed, 2021 Jun 01;38(2):85-93.
    PMID: 33973578 DOI: 10.47665/tb.38.2.046
    This research was undertaken to evaluate the nematicidal activity of various concentrations of aqueous tinctures of 80 plant species towards L1-2 of S. papillosus. For the experiment with larvae of S. papillosus, there were used 0.19%, 0.75% and 3.00% aqueous tinctures of plants. Out of 80 tested species, nematicidal activity against L1-2 of S. papillosus was displayed by 20 plants. The greatest activity (LC50 = 0.060-0.069%) towards larvae of S. papillosus was exerted by Teucrium polium, Achillea millefolium, Genista tinctoria and Ulmus laevis. Less expressed nematicidal activity (LC50 = 0.070-0.079%) was recorded for Thalictrum minus, Stachys recta, Falcaria vulgaris, Lavatera thuringiaca. Even lower effect (LC50 = 0.080-0.089%) was shown by aqueous tinctures of Mentha × piperita, Achillea millefolium, Salvia nutans, Eryngium campestre and Cerasus fruticosa. The following plants could be arranged in declining order of effectiveness of nematicidal activity (LC50 = 0.090-0.165%) Malus sylvestris, Tragopogon orientalis, Erigeron annuus, Grindelia squarrosa, Urtica dioica, Daucus carota, Medicago sativa, Carduus acanthoides, Ulmus minor and Hieracium umbellatum. A far weaker effect on the nematodes was displayed by Bromopsis inermis and Tragopogon podolicus. Aqueous tinctures of 60 other studied species of plants exhibited low nematicidal activity in 3.00% aqueous tincture, while in 0.19% and 0.75% aqueous tinctures, no nematicidal activity was seen. The results of the research suggest that in the conditions of natural ecosystems, some species of plants of the Apiaceae, Asteraceae, Fabaceae, Lamiaceae, Malvaceae, Rosaceae, Ulmaceae and Urticaceae families could reduce vitality of free-living L1-2 larvae of S. papillosus.

  15. Fulltext Natural Wolbachia infection in field-collected Anopheles and other mosquito species from Malaysia
    Wong ML, Liew JWK, Wong WK, Pramasivan S, Mohamed Hassan N, Wan Sulaiman WY, et al.
    Parasit Vectors, 2020 Aug 12;13(1):414.
    PMID: 32787974 DOI: 10.1186/s13071-020-04277-x
    BACKGROUND: The endosymbiont bacterium Wolbachia is maternally inherited and naturally infects some filarial nematodes and a diverse range of arthropods, including mosquito vectors responsible for disease transmission in humans. Previously, it has been found infecting most mosquito species but absent in Anopheles and Aedes aegypti. However, recently these two mosquito species were found to be naturally infected with Wolbachia. We report here the extent of Wolbachia infections in field-collected mosquitoes from Malaysia based on PCR amplification of the Wolbachia wsp and 16S rRNA genes.

    METHODS: The prevalence of Wolbachia in Culicinae mosquitoes was assessed via PCR with wsp primers. For some of the mosquitoes, in which the wsp primers failed to amplify a product, Wolbachia screening was performed using nested PCR targeting the 16S rRNA gene. Wolbachia sequences were aligned using Geneious 9.1.6 software, analyzed with BLAST, and the most similar sequences were downloaded. Phylogenetic analyses were carried out with MEGA 7.0 software. Graphs were drawn with GraphPad Prism 8.0 software.

    RESULTS: A total of 217 adult mosquitoes representing 26 mosquito species were screened. Of these, infections with Wolbachia were detected in 4 and 15 mosquito species using wsp and 16S rRNA primers, respectively. To our knowledge, this is the first time Wolbachia was detected using 16S rRNA gene amplification, in some Anopheles species (some infected with Plasmodium), Culex sinensis, Culex vishnui, Culex pseudovishnui, Mansonia bonneae and Mansonia annulifera. Phylogenetic analysis based on wsp revealed Wolbachia from most of the mosquitoes belonged to Wolbachia Supergroup B. Based on 16S rRNA phylogenetic analysis, the Wolbachia strain from Anopheles mosquitoes were more closely related to Wolbachia infecting Anopheles from Africa than from Myanmar.

    CONCLUSIONS: Wolbachia was found infecting Anopheles and other important disease vectors such as Mansonia. Since Wolbachia can affect its host by reducing the life span and provide resistance to pathogen infection, several studies have suggested it as a potential innovative tool for vector/vector-borne disease control. Therefore, it is important to carry out further studies on natural Wolbachia infection in vector mosquitoes' populations as well as their long-term effects in new hosts and pathogen suppression.

  18. Fulltext Investigation on antimicrobial activity of root extracts of Thespesia populnea Linn
    Senthil-Rajan D, Rajkumar M, Srinivasan R, Kumarappan C, Arunkumar K, Senthilkumar KL, et al.
    Trop Biomed, 2013 Dec;30(4):570-8.
    PMID: 24522124 MyJurnal
    Many medicinal plants have been used for centuries in daily life to treat microbial diseases all over the world. In this study, the in vitro antibacterial activity of aqueous and ethanol root extracts of Thespesia populnea Linn were investigated. Antimicrobial properties of T. populnea Linn was evaluated against five pathogenic bacteria and two fungi. Disc diffusion method and minimum inhibitory concentration (MIC) were determined by broth serial dilution method. The ciprofloxacin (5 μg/ml) and flucanozole (100 units/disc) were used as positive controls for bacteria and fungi respectively. Different concentrations (50, 100, 150 μg/ml) of ethanolic and aqueous root extracts of T. populnea were checked for the dose dependent antibacterial activity. Thespesia populnea showed broad spectrum antimicrobial activity against gram positive and gram negative bacteria and maximum inhibition by ethanolic extract was observed at higher dose (250 μg/ml) as 27±0.2mm. The MIC of the ethanol extract was 10 μg/ml for Staphylococcus aureus and 750 μg/ml for Candida albicans. The antifungal activity offered against S. aureus by the ethanolic extract is more than the aqueous extract. The results concluded that the anti-microbial activity of T. populnea was dose dependent. As the concentration increased the inhibition zone also increased. Flavonoids and tannins present in the extracts may be responsible for the antimicrobial activity.

    Ho YC, Norli I, Alkarkhi AF, Morad N
    J Water Health, 2015 Jun;13(2):489-99.
    PMID: 26042980 DOI: 10.2166/wh.2014.100
    In view of green developments in water treatment, plant-based flocculants have become the focus due to their safety, degradation and renewable properties. In addition, cost and energy-saving processes are preferable. In this study, malva nut gum (MNG), a new plant-based flocculant, and its composite with Fe in water treatment using single mode mixing are demonstrated. The result presents a simplified extraction of the MNG process. MNG has a high molecular weight of 2.3 × 10⁵ kDa and a high negative charge of -58.7 mV. From the results, it is a strong anionic flocculant. Moreover, it is observed to have a branch-like surface structure. Therefore, it conforms to the surface of particles well and exhibits good performance in water treatment. In water treatment, the Fe-MNG composite treats water at pH 3.01 and requires a low concentration of Fe and MNG of 0.08 and 0.06 mg/L, respectively, when added to the system. It is concluded that for a single-stage flocculation process, physico-chemical properties such as molecular weight, charge of polymer, surface morphology, pH, concentration of cation and concentration of biopolymeric flocculant affect the flocculating performance.
