Cell-free Fetal Nucleic Acids in Amniotic Fluid

L. Hui, D.W. Bianchi https://academic.oup.com/humupd/article/17/3/362/1387873 Cell-free fetal nucleic acids have mainly been examined in maternal plasma. Cell-free fetal nucleic acids have been found in greater concentrations in amniotic fluid than in maternal plasma. It is physiologically distinct from nucleic acids found in maternal plasma. What is Amniotic Fluid? Amniotic fluid is formed in the first…

New Nanotech to Detect Cancer Early

Dr. Joshua Smith is a research scientist and team lead for IBM’s Nanobiotechnology Program. Around forty percent of the population will receive a cancer diagnosis within their lifetime. Accurate early diagnosis drastically increases the survival rate of most cancers. Current methods for diagnosis are invasive, costly, and not reliably accurate. Dr. Joshua Smith and his…

Self-assembling Peptide Scaffolds For Regenerative Medicine

John B. Matson, Samuel I. Stupp Bio-materials made from small peptide chains are ideal for creating scaffolds for tissue regeneration. Small peptides can assemble into spheres, cylinders, tubes, and many other useful scaffolding structures. Classes of Filamentous Supra-molecular Scaffolds Peptide amphiphiles are short chain peptides with a hydrophobic tail attached to a lipid chain capable of self…
