  • Over the past several years, scientists from the United States and around the world have been using a technique called DNA sequencing to unlock the genetic code of many different organisms. With code in hand, scientists can design sophisticated experiments that will inform our understanding of how an organism develops and functions. To date, they have carried out partial or complete DNA sequencing on human, mouse, rat, bacterial, and plant genomes. A major finding that was confirmed from these efforts is that most biologic functions are genetically conserved within and between species....

  • You need to adjust the hand a little so it tilts away from the body. Many Blender animators prefer to use the manipulators for bone rotations like this, as they give excellent visual feedback. If the Transformation Manipulator isn’t showing, enable it on the 3D header, or with Ctrl-Space. When the manipulator is visible, set it to Rotation mode. With the manipulator set to the default Global mode on the header, it’s not very useful. Change it to Normal, which will cause the manipulator to align itself with the active bone.

  • A recent report 5 by Dr. K. Kellie Leitch to the Minister of Health highlighted three major areas of focus to improve child health. Genomics will play a critical role in addressing two of these areas: obesity and healthy lifestyles, and mental health and chronic illness. Improving child health through genomics directly aligns with the goals of the National Science and Technology strategy, focusing our S&T investment in the high priority area of health and related life sciences and technologies, which is identified as one of four areas of focus for investment.

  • Researchers have theorized that anti-inflammatory medications may help prevent diseases, such as coronary artery diseases (CAD), cardio vascular diseases (CVD), stroke, colon cancer and Alzheimer’s. Several recent findings from different laboratories in the world employing case-control human studies and/or specific animal models for chronic human diseases support these ideas.

  • Sindbis virus (SV) is the prototype of alphaviruses which are a group of widely distributed human and animal pathogens. Heterogeneous nuclear ribonucleoprotein (hnRNP) A1 is an RNA-binding protein that shuttles between the nucleus and the cytoplasm. Our recent studies found that hnRNP A1 relocates from nucleus to cytoplasm in Sindbis virus (SV)-infected cells. hnRNP A1 binds to the 5′ UTR of SV RNA and facilitates the viral RNA replication and translation.

  • The state of a normal or diseased cell is determined by external signals and by its intrinsic gene expression pat- tern. Transcription factors (TFs) are major regulators of gene expression, typically controlling more than one gene and acting in concert. Such TF-gene interactions can be described as networks, which are crucial to understand hierarchies of gene expression regulation. The identifica- tion of TF binding sites (TFBSs) in genomic DNA sequences has played an important role in predicting tran- scriptional networks.

  • There is lively debate about whether Alu serves some larger purpose in primate genomes or is merely “selfish DNA” that has been successful in its mode of replication. Alu insertions in coding exons are implicated in a number of human diseases, including neurofibromatosis, thalassemia, cancer, and heart attack. However, the vast majority of Alus are located in introns or intergenic regions, where they appear to have no phenotypic effect.

  • Most (78%) mitochondrial genomes in the studied mutant strain of Drosophila subobscura have undergone a large-scale deletion (5 kb) in the coding region. This mutation is stable, and is transmitted intact to the offspring. This animal model of major rearrangements of mitochondrial genomes can be used to analyse the involvement of the nuclear genome in the production and maintenance of these rearrangements.

  • The unplanned crossbreeding had also threatened the genetic resources base of the country. Although efforts were made at developing breeding program for various livestock species in the country, all did not materialize due to lack of commitment of and consultation with various stakeholders. There is, therefore, a pressing need to develop a breeding strategy that addresses various livestock species and the diverse agro-ecologies that exist in the country.

  • MicroRNAs (miRNAs) have been proven to play important roles at the post-transcriptional level in animals and plants. To investigate clustering patterns and specific sequence characteristics in the flanking regions of plant miRNA genes, we performed genome-wide analyses ofArabidopsis thaliana, Populus trichocarpa, Oryza sativaand Sorghum bicolor.

  • Alu transposons are found only in primate genomes and have accumulated in large numbers since primates diverged from other mammals. Human chromosomes contain more than one million Alu copies, equaling about 10% of the genome by mass. This accumulation was made possible by a transposition mechanism that reverse transcribes Alu mRNAs into mobile DNA copies. Another transposon, the long interspersed element (LINE) L1, supplies a specialized reverse transcriptase enzyme needed for Alu to jump. Hence, Alu and L1 exist in a sort of molecular symbiosis.

  • The Board’s Patient Care Assessment (PCA) program, receives three kinds of reports from hospitals: Major Incident Reports (MIR), detailing events resulting in death or serious impairment of a patient; and Annual and Semi-Annual Reports which detail a facility’s progress with respect to its patient safety program. Having eliminated a years long backlog of report review, the PCA Committee turned its focus to encouraging greater reporting compliance by hospitals, faster and more detailed review and more comprehensive data analysis.
