  • A very large body of evidence thus suggests that plant phenolics, clearly present in higher concentrations in organic than conventional foods, are effective in the fight against cancer, heart disease and age-related neurological dysfunction. (i-sis.org.uk)
  • For example, the methods used to generate nerve cells from patient fibroblasts tend to yield low numbers of cells, and those that are produced are not fully functional. (genengnews.com)
  • As well as making more mature nerves, Dr. Philpott's lab is now using similar methods to improve the function of insulin-producing pancreas cells for future therapeutic applications. (genengnews.com)

  • Single-cell RNA-sequencing analysis showed that compared with APP/PS1 mouse microglia, APP/PS1;TERF2DN mouse microglia displayed a modest decline in disease-associated microglia, accompanied by an altered direction of biological process branching from antigen synthesis and arrangement to ribonucleoprotein complex biogenesis.

  • Rebuild the walls is focused on the fact that people's skin, cell walls and other barriers are under assault by decades of wear and tear, which results in decreased sensation, increased response time, chronic inflammation and frailty. (wikipedia.org)
