The present work was done in order to develop and find out suitable conversion methods for coconut husk wastes into value-added products. It is well-known that coconuts husk waste is hydrophobic therefore ethanol with different doses was used as a surfactant to enhance the removal efficiency. Treated samples at different adsorbent amounts, sintering temperatures & sintering time, stirring time, ph, and solution temperatures for color removal of Methylene Blue (MB) & Rhodamine B (RhB) and ammonium concentration were evaluated by using UV-Visible Spectroscopy. At 300°C, results showed complete removal for MB and more than 75% for RhB, whereas removal of ammonium ion reached around 52% when sintering product from husk waste was used. Further investigation was carried out for ammonium ion to understand the desorption kinetic behaviors and isotherm models. Kinetics indicated that desorption of ammonium ion followed pseudo-first order equation. Adsorption thermodynamic parameters such as ΔG, Δh, and ΔS followed Van’t hoff plot for adsorption and found to be negative which indicated that the adsorption process for ammonium onto coconut husk was physical, spontaneous and exothermic.

目的:评价还原性谷胱甘肽(GSh)和烟酸联合应用对蛋白质氧化应激、内质网应激(ER)、糖基化和聚合αβ晶状体蛋白的人晶状体上皮(hLE)细胞治疗高葡萄糖水平的影响。方法:培养hLE细胞并暴露于25 mmol/L葡萄糖中以促进高糖环境。各组细胞用三种不同的剂量组合进行联合治疗:10μmol/L GSh+2μmol/L烟酸,30μmol/L GSh+25μmol/L烟酸,100μmol/L GSh+25μmol/L烟酸。培养72h后,用ELISA法测定蛋白羰基(PCC)和葡萄糖反应蛋白(GRP78)的含量。培养2wk后,对糖基化终末产物(AGEs)进行检测,用Western Blot检测αβ晶状体蛋白的表达。所有数据分析均采用SPSS 18.0统计软件包。结果:与对照组相比,联合治疗组的PCC和GRP78水平没有显著降低(P>0.05)。相反,与对照组相比,GSh和烟酸联合治疗组的AGEs水平明显下降(Ph联合治疗组与GSh和烟酸联合治疗组αβ晶状体蛋白表达都有所降低。结论:结果表明,GSh和烟酸联合应用可抑制高血糖人hLE细胞蛋白质的聚合,防止糖基化,并且通过AGEs途径在预防糖尿病性白内障中发挥积极作用。

DNA photolyase is a photoreactivation enzyme which has a role in the mechanism of DNA repair. The existence of DNA photolyase gene could affect the success of mutation process. SM026h is a drought tolerance branching line of kenaf identified by Research Institute for Tobacco and Fibre Crops, Karangploso, Malang, Indonesia which has a potential as a source for mutation breeding. In this research, cloning and sequencing of the DNA photolyase gene of line SM026h were conducted. The DNA of SM026h leaves was isolated using DNeasy Kit, then was amplified by Polymerase Chain Reaction (PCR) using AC1 as a forward primer, paired with AC3R or AC4R as reverse primers and checked using electrophoresis on a 0.7% agarose gel. The AC1-AC3R primer pair produced a DNA fragment with a size of 750 bp, whereas the AC1-AC4R primer pair produced a DNA fragment of 1000 bp in size. Cloning of the AC1-AC3R and AC1-AC4R fragments was done prior to sequencing. Preparation for cloning was done by running and extracting the PCR products from a 0.7% Low Melting Agarose (LMA), and then ligating them to a pCR21 plasmid using an electroporation method. Two sub-fragments of each AC1-AC3R and AC1-AC4R fragments were identified. They were 600 bp and 500 bp, resulting from the AC1-AC3R fragment, and 1300 bp and 500 bp, resulting from the AC1-AC4R fragment. The sequencing result of those sub-fragments was analyzed using a Basic Local Alignment Search Tool (BLAST) program. It was shown that the sequences have a degree of homology to DNA photolyase sequence of Arabidopsis thaliana A. thaliana, Cucumis sativus, Spinacia oleracea, Stellaria longipes and Oryza sativa. These suggested that the kenaf line SM0026h possesses the DNA photolyase gene. however, further study needs to be done to ascertain that the gene was not the cryptochrome.

Wurtzite hexagonal ZnO semiconductor nano-rods (NRs) thin films were grown on silicon substrates and silver wire with diameter equal 68 nm. Sol gel (SG) and aqueous chemical growth (ACG) methods by two steps of preparation (seed layers and nano-rod growth) are used for samples preparation. The structural and morphological properties are evaluated using X-ray diffraction (XRD) and scanning electron microscope (SEM). The proposed iron ion sensor has shown good linearity for a wide concentration range from 0.078 M/L to 0.26 M/L of iron ions. The results show that the electrode is highly sensitive to iron ions with a slope around 47.8 mV/decade with a regression coefficient R2 = 0.96.

Tuberculosis is an infectious disease caused by the Mycobacterium tuberculosis. Mycobacterium tuberculosis will form the primary focus or Ghon focus in the lungs of infected people. The primary focus can break and get into the bloodstream and/or lymph to the entire body, including the central nervous system, especially the brain. Tuberculosis infection in the brain can cause microglia secrete inflammatory factors such as TNF-α and IL-1β is emerging as the body’s immune response. The factors that can trigger microglia to secrete iNOS (Inducible Nitric Oxide Synthase) in order to protect the brain from attacking bacteria. iNOS is shown to have an important role in tuberculosis infection in the brain. TNF-α is a pro-inflammatory cytokine which is mostly produced by macrophages/microglia through several mechanisms. Therefore, to investigate how the expression of TNF-α and iNOS in the brain tissue of the mice is not infected with tuberculosis, tuberculosis infection with an incubation period of 8 weeks and 16 weeks. This study is a semiquantitative study by comparing the amount of expression of TNF-α and iNOS and all three groups of samples with treatment as has been mentioned. The expressions observation of TNF-α and iNOS in brain cell tissue of mice was conducted using immunohistochemical staining, and was seen in a microscope with a magnification of ×100. Brain cells that express TNF-α and iNOS are brown core, cytoplasm and cell walls. The results were obtained by the longer exposure to infection of the higher expression of TNF-α (r > 0688) and the expression of iNOS decreased (–0.993).
