| 1 | Morphological and biochemical responses of Oryza sativa L.(cultivar MR219) to ion beam irradiation显示文摘Objective: Heavy ion beam, which has emerged as a new mutagen in the mutation breeding of crops and ornamental plants, is expected to result in the induction of novel mutations. This study investigates the morphological and biochemical responses of Oryza sativa toward different doses of carbon ion beam irradiation. Methods: In this study, the dry seeds of O. sativa were irradiated at 0, 20, 40, 60, 80, 100, and 120 Gy, followed by in-vitro germination under controlled conditions. Morphological and biochemical studies were conducted to investigate the morphological and physiological responses of O. sativa towards ion beam irradiation. Results: The study demonstrated that low doses(10 Gy) of ion beam have a stimulating effect on the height, root length, and fresh weight of the plantlets but not on the number of leaves. Meanwhile, doses higher than 10 Gy caused reductions in all the morphological parameters studied as compared to the control samples. The highest total soluble protein content [(2.11±0.47) mg/g FW] was observed in plantlets irradiated at 20 Gy. All irradiated plantlets were found to have 0.85% to 58.32% higher specific activity of peroxidase as compared to the control samples. The present study also revealed that low doses of ion beam(10 and 20 Gy) had negligible effect on the total chlorophyll content of O. sativa plantlets while 40 Gy had a stimulating effect on the chlorophyll content. Plantlets irradiated between 40 to 120 Gy were shown to be 0.38% to 9.98% higher in total soluble nitrogen content which, however, was not significantly different from the control samples. Conclusions: Carbon ion beam irradiation administered at low to moderate doses of 10 to 40 Gy may induce O. sativa mutants with superior characteristics. | Anna Pick Kiong LING Ying Chian UNG Sobri HUSSEIN Abdul Rahim HARUN Atsushi TANAKA Hase YOSHIHIRO | 2013 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013，14，12： | 5 |
| 2 | Comparative effects of plant growth regulators on leaf and stem explants of Labisia pumila var. alata显示文摘Objective: Labisia pumila var. alata, commonly known as 'Kacip Fatimah' or 'Selusuh Fatimah' in Southeast Asia, is traditionally used by members of the Malay community because of its post-partum medicinal properties. Its various pharmaceutical applications cause an excessive harvesting and lead to serious shortage in natural habitat. Thus, this in vitro propagation study investigated the effects of different plant growth regulators (PGRs) on in vitro leaf and stem explants of L. pumila. Methods: The capabilities of callus, shoot, and root formation were evaluated by culturing both explants on Murashige and Skoog (MS) medium supplemented with various PGRs at the concentrations of 0, 1, 3, 5, and 7 mg/L. Results: Medium supplemented with 3 mg/L indole-3-butyric acid (IBA) showed the optimal callogenesis from both leaf and stem explants with (72.34±19.55)% and (70.40±14.14)% efficacy, respectively. IBA was also found to be the most efficient PGR for root induction. A total of (50.00±7.07)% and (77.78±16.47)% of root formation were obtained from the in vitro stem and leaf explants after being cultured for (26.5±5.0) and (30.0±8.5) d in the medium supplemented with 1 and 3 mg/L of IBA, respectively. Shoot formation was only observed in stem explant, with the maximum percentage of formation ((100.00±0.00)%) that was obtained in 1 mg/L zeatin after (11.0±2.8) d of culture. Conclusions: Callus, roots, and shoots can be induced from in vitro leaf and stem explants of L. pumila through the manipulation of types and concentrations of PGRs. | Anna Pick Kiong LING Kinn Poay TAN Sobri HUSSEIN | 2013 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013，14，7： | 2 |

| 11 | Anti-neuroinflammatory responses in lipopolysaccharide-stimulated BV2 microglial cells upon treatment with methanol extract of Panax ginseng root显示文摘OBJECTIVE:To investigate the anti-neuroinflammatory properties of Panax ginseng(P.ginseng)root by measuring the levels of nitric oxide(NO),tumour necrosis factor-alpha(TNF-α),interleukin-6(IL-6),and interleukin-10(IL-10)in lipopolysaccharide(LPS)-stimulated BV2 microglia cells.METHODS:Maximal non-toxic dose(MNTD)of methanol extract of P.ginseng root culture on BV2 microglia cells was first determined via 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay,followed by treatment and LPS stimulation of cells,and the measurement of NO using Griess assay and TNF-α,IL-6,and IL-10 using ELISA assay.RESULTS:The MNTD of P.ginseng root extract was determined to be(587±57)µg/mL.Following that,NO and IL-6 levels were found to be insignificantly reduced by 6.88%and 0.14%respectively in stimulated cells upon treatment with MNTD.Treatment with½MNTD yielded similar insignificant result,with only a reduction of 3.58%and 0.08%in NO and IL-6 levels respectively.However,TNF-αand IL-10 levels were significantly downregulated by 15.64%and 34.96%respectively upon treatment with P.ginseng root extract at MNTD.CONCLUSION:Methanol extract of P.ginseng root culture did not show any significant anti-inflammatory effects on NO and IL-6 levels,but might potentially possess both anti-neuroinflammatory and pro-neuroinflammatory properties through the downregulation of TNF-αand IL-10 respectively. | Chien Yi Koay Anna Pick Kiong Ling Ying Pei Wong Rhun Yian Koh Sobri Hussein | 2021 | Journal of Traditional Chinese Medicine2021，41，2： | 0 |

| 13 | Spatial Model of Sky Brightness Magnitude in Langkawi Island, Malaysia显示文摘Sky brightness is an essential topic in the field of astronomy,especially for optical astronomical observations that need very clear and dark sky conditions.This study presents the spatial model of sky brightness magnitude in Langkawi Island,Malaysia.Two types of Sky Quality Meter(SQM) manufactured by Unihedron are used to measure the sky brightness on a moonless night(or when the Moon is below the horizon),when the sky is cloudless and the locations are at least 100 m from the nearest light source.The selected locations are marked by their GPS coordinates.The sky brightness data obtained in this study were interpolated and analyzed using a Geographic Information System(GIS),thus producing a spatial model of sky brightness that clearly shows the dark and bright sky areas in Langkawi Island.Surprisingly,our results show the existence of a few dark sites nearby areas of high human activity.The sky brightness of 21.45 mag arcsec^(-2) in the Johnson-Cousins V-band,as the average of sky brightness equivalent to 2.8 ×10^(-4) cd m^(-2) over the entire island,is an indication that the island is,overall,still relatively dark.However,the amount of development taking place might reduce the number in the near future as the island is famous as a holiday destination. | Mohammad Redzuan Tahar Farahana Kamarudin Roslan Umar Mohd Khairul Amri Kamarudin Nor Hazmin Sabri Karzaman Ahmad Sobri Abdul Rahim Mohd Sharul Aikal Baharim | 2017 | Research in Astronomy and Astrophysics2017，17，4： | 0 |
