  • Advancing vaccine adjuvants: exploring cutting-edge platforms for improved immunization
    News - 21 Jul 2023
    A group of authors summarized adjuvant mechanisms, characteristics, and applications, seeking to overcome current vaccine limitations.
  • What is the Y Chromosome?
    Health - 21 Jul 2023
    There are 23 pairs of chromosomes in the human body which include 22 pairs of autosomal chromosomes that are common to both men and women and one pair of sex chromosomes that determine an individual’s...
  • Xenobiotics and Redox Metabolism
    Life Sciences - 20 Jul 2023
    What are xenobiotics?
  • Metabolism Investigation and Manipulation
    Life Sciences - 20 Jul 2023
    Metabolic pathways are complex and often interdependent. Any change in the pathways can give rise to complex disorders. For example, imbalance of the glucose homeostasis and carbohydrate metabolism is...
  • Ribozyme Discovery
    Life Sciences - 20 Jul 2023
    Ribozymes are catalytic RNA molecules involved in protein synthesis. Most biological catalysts are enzymes and until around four decades ago, experts believed that only enzymes could serve as...
  • Artificial Ribozymes
    Life Sciences - 20 Jul 2023
    Ribozymes exist in nature as catalytic RNA molecules that either aid the hydrolysis of their own phosphodiester bonds or cause the hydrolysis of bonds in other RNAs. They also catalyze the...
  • What is Lentivirus?
    Life Sciences - 20 Jul 2023
    Viruses are small obligate intracellular parasites with either a RNA or DNA genome that are surrounded by a protective protein coat and transfer their genetic material to infected cells.
  • Systemic Telomere Length and Aging
    Life Sciences - 20 Jul 2023
    Telomere length is the result of the equilibrium between shortening and lengthening mechanisms, and in many different organisms there is a decrease in length with increasing age. This suggests that...
  • Telomeres and Cancer
    Life Sciences - 20 Jul 2023
    A ribonucleoprotein enzyme complex known as telomerase maintains telomere length in cancer cells by adding TTAGGG repeats onto the telomeric ends, compensating for the normal shortening of telomeres...
  • MicroRNA Nomenclature
    Life Sciences - 20 Jul 2023
    MicroRNAs (miRNAs) are evolutionary conserved small non-coding RNA molecules that post-transcriptionally regulate gene expression by base-pairing to mRNAs. Recent evidence shows that miRNA-mediated...
