    In the current era of market globalization, people in the world could not evade from imported food products. The demand for imported food products such as chocolates, biscuits and sweets are projected to escalate steadily over the next decade as a result of increasing consumption. Unfortunately, most of the imported food products do not have Halal Logo or with doubted Halal Logo. The demand for Halal food and other Islamic consumer goods is increasing. This study will be beneficial to provide new information of Halal products and easier for Muslim to choose the permissible products according to Syariah Law. The main objective of this study was to determine of suspected Non Halal processed food products by using porcine mitochondrial 12S rDNA and porcine leptin gene. A total of 66 samples of suspected Non Halal food products were screened for porcine mitochondrial 12S rDNA gene and porcine leptin gene primer pairs from the genomic DNA. The PCR products were separated on 2% agarose gel and visualized under UV light. Thirty seven samples were positive with mitochondrial 12S rDNA gene whilst 59 samples were positive with leptin gene. From these, 33 were positive with both primers. These results indicate that the samples of processed food products contained porcine derivatives. From the detection of the DNA products by using the two set of primers, leptin gene was concluded to be more specific than the mitochondrial 12S rDNA gene. Some of the PCR products of processed food products of mitochondrial 12S rDNA gene and leptin gene were sent to Genomic Bioscience & Technology Company for DNA sequencing. Then, the sequences of the DNA were used for sequence alignment in order to get a probe specific to Halal food. Two probes were obtained, one with 24 mers and 13 mers, respectively. Mitochondrial 12S rDNA gene was chosen to make a probe because it has more quality DNA for a probe compared to leptin gene. In addition, findings from this research also provide new information in the detection of pork in foods products for Halal authentication

    A Dual Fluorescence–Spin Label Probe for Visualization and Quantification of Target Molecules in Tissue by Multiplexed FLIM–EPR Spectroscopy

    Simultaneous visualization and concentration quantification of molecules in biological tissue is an important though challenging goal. The advantages of fluorescence lifetime imaging microscopy (FLIM) for visualization, and electron paramagnetic resonance (EPR) spectroscopy for quantification are complementary. Their combination in a multiplexed approach promises a successful but ambitious strategy because of spin label-mediated fluorescence quenching. Here, we solved this problem and present the molecular design of a dual label (DL) compound comprising a highly fluorescent dye together with an EPR spin probe, which also renders the fluorescence lifetime to be concentration sensitive. The DL can easily be coupled to the biomolecule of choice, enabling in vivo and in vitro applications. This novel approach paves the way for elegant studies ranging from fundamental biological investigations to preclinical drug research, as shown in proof-of-principle penetration experiments in human skin ex vivo

    The U-232 nucleus was studied in order to search for a hyperdeformed band built upon the third minimum of the fission barrier. Upper limits for the percentage population of a hypothetical hyperdeformed band relative to the ground state band are given

    Race in health research: Considerations for researchers and research ethics committees

    Get PDF
    This article provides ethical guidance on using race in health research as a variable or in defining the study population. To this end, a plain, non-exhaustive checklist is provided for researchers and research ethics committees, preceded by a brief introduction on the need for justification when using race as a variable or in defining a study population, the problem of exoticism, that distinctions pertain between race, ethnicity and ancestry, the problematic naming of races, and that race does not serve well as a presumed biological construct in genetic research

    WOS: 000208079500032This work was performed to understand the structure of neutron-rich fission fragments around the 130 mass region. A thin U-235 target was bombarded by a N-14 beam with 10 MeV/A from the Separated Sector Cyclotron at the iThemba Laboratory for Accelerator Based Sciences, Cape Town, South Africa. The main goal was to detect and identify fission fragments and to obtain their mass distribution by using solar cell detectors in the AFRODITE (African Omnipurpose Detector for Innovative Techniques and Experiments) spectrometer. The X-rays emitted from fission fragments were detected by LEP (Low Energy Photon) detectors and gamma-rays emitted from excited states of the fission fragments were detected by CLOVER detectors in the spectrometer.University of Istanbul [UP-12/040199, UP-8/270598]This work was supported by the Research Fund of the University of Istanbul, Project numbers UP-12/040199 and UP-8/270598

    Transforming Organisations through Systems Analysis: Deploying new techniques for organisational analysis in IS development

    Excited states in Ta-165 were populated in the Nd-142(Al-27,4n)Ta-165 and Pr-141(Si-28,4n)Ta-165 reactions and investigated using the AFRODITE array. The yrast rotational decay sequence up to spin 53/2(-) is identified and assigned to the [514]9/2(-) configuration. The nuclear shape is investigated using total Routhian surface calculations. The experimental results are discussed in relation to existing data in the neighboring Ta isotopes and results from cranked shell model calculations. Unexpectedly large signature splitting, for a high-Omega configuration, is observed in the yrast band. Further discrepancies are observed between theoretical and experimental values for the band crossing frequency and signature splitting of the B(M1)/B(E2) ratios. The possibility that these discrepancies are a consequence of a large deviation from an axially symmetric nuclear shape is investigated
