  • MicroRNA Profiling
    Life Sciences - 26 Feb 2019
    MicroRNAs, or miRNAs, are small RNAs that regulate gene expression after transcription has taken place.
  • Melanin Production Pathway
    Life Sciences - 26 Feb 2019
    Melanin is synthesised in cytoplasmic organelles called melanosomes, which reside in skin cells and hair follicles called melanocytes. This process is known as melanogenesis.
  • Micro-PET Principles, Strengths, and Weaknesses
    Life Sciences - 26 Feb 2019
    Positron emission tomography (PET) is a nuclear imaging tool for molecular and functional imaging of biological processes. While functional imaging is used to monitor parameters such as perfusion and...
  • Micro-MRI Principles, Strengths, and Weaknesses
    Life Sciences - 26 Feb 2019
    Magnetic resonance imaging (MRI) is a technique that generates images by exploiting the nuclear magnetic behavior of different atoms in a sample tissue placed in a magnetic field. It is a non-invasive...
  • Role of Transcription Factors
    Life Sciences - 26 Feb 2019
    Transcription refers to the creation of a complimentary strand of RNA copied from a DNA sequence. This results in the formation of messenger RNA (mRNA), which is used to synthesize a protein via...
  • Senescence and Aging
    Life Sciences - 26 Feb 2019
    Senescence occurs in three different scenarios: senescence due to normal aging; senescence due to age-related diseases, and senescence induced due to therapy
  • Histone Modification
    Life Sciences - 26 Feb 2019
    Histones are proteins that condense and package DNA neatly into chromosomes. Modifications to these proteins affect different processes in the cell such as the activation/inactivation of...
  • Bioprinting Applications
    Life Sciences - 26 Feb 2019
    Bioprinting involves the use of 3D printing technology to build tissues and organs. It has been trialed in several areas, including tissue engineering, organ transplantation, drug screening and cancer...
  • What are Bacteriophages?
    Life Sciences - 26 Feb 2019
    Bacteriophages are small, virus-like organisms that infect bacteria. They are comprised of a protein capsule around an RNA or DNA genome.
  • Does Allostery Exist in Monoclonal Antibodies?
    Life Sciences - 26 Feb 2019
    Allosteric interaction is particularly useful in the case of therapeutic biologics.
