  • disable the entire circadian system of the mice
  • jump-start individual clocks
  • "No one realized that the liver or skin could be so directly affected by light."
  • ...2 more annotations...
  • despite the shutdown of all other body clocks, including the central brain clock, the liver knew what time it was, responded to light changes as day shifted to night and maintained critical functions, such as preparing to digest food at mealtime and converting glucose to energy.
  • it's easy for people's circadian systems to get confused, he said. In turn, that can lead to depression, allergies, premature aging, cancer and other health problems. Further mice experiments could uncover ways to make human internal clocks "less misaligned,"

  • They become disconnected, and as a result, people lose their ability to think clearly and remember things. We're demonstrating that exercise training strengthens these connections."
  • walking may decrease cerebral blood flow and improve brain function in older adults with mild cognitive impairment.

    correlation between exercise and memory. i'd be interested to see the long-term effects.

  • Hematopoietic stem cells
  • bone marrow is damaged and no longer able to produce healthy blood cells
  • Though cytokines were once believed to be indispensable for ex vivo HSC growth, the research team hypothesized other new approaches as suitable alternatives.
  • ...2 more annotations...
  • ompound called UM171,
  • specific polymer, improved the results by supporting long-term HSC expansion.

  • "What we can conclude is that a baby's autonomic nervous system is able to sense the electrical environment and it seems as though a baby is more relaxed when grounded,"
  • redesigning incubators to ground babies and cancel out the electrical field
  • ryleighnyp on 07 Jun 23
     
    I think a possible research idea could be redesigning NICU incubators to allow for less electromagnet interference with the babies with the use of grounding.

    Interesting, for sure. Two things... the actual measurements they made on children (skin tests, etc.) are a no-go for us. I'm not sure what our model system could be for checking the electrical outputs of whatever design changes were made. We would need to know a lot more about the current setup in NICUs. There is no doubt a lot of design in how things are currently set up. Essentially: why things are set up the way they are right now? You would have to know every variable currently considered, and then look for spots where simple changes can be made. Second thing: go back to the ISEF categories in Engineering and check out how those projects look at the national level. Just go get a feel. Engineering is a bit different from typical "hypothesis testing" seen in most natural sciences. Very cool, but different. Give it a look.

shared by izzy kelly on 02 Jun 23 - No Cached
  • Synaptic adhesion proteins are specialized proteins that bind to create physical connections between brain cells
  • utoantibodies against the synaptic protein neurexin 1α,
  • which is expressed by one cell in the synapse and binds to proteins known as neuroligins on the other cell in the synapse,
  • ...2 more annotations...
  • neurexin 1α can cause schizophrenia-related changes, at least in mice,
  • autoantibodies is important for improving symptom control
  • izzy kelly on 02 Jun 23
     
    autoantibodies that target neurexin 1a could possibly play a role in the development of schizophrenia. possible treatment with identifying autoantibodies

  • implications for brain plasticity, diseases like autism spectrum disorders, schizophrenia, and dementia, which arise when the brain's networks are not maintained properly, and the ability of the brain to fight off infection and repair the damage following a stroke or other traumatic injury.

      It would be interesting to look deeper into these process and the mechanism behind maintenance of the brain.
  • This research shows that the signals in our brain that modulate the sleep and awake state also act as a switch that turns the immune system off and on."
  • ...2 more annotations...
  • plasticity, the ongoing process by which the complex networks and connections between neurons are wired and rewired during development and to support learning, memory, cognition, and motor function.

      I think it would be cool to look into the difference between this function in people's brains with and without learning disabilities.
  • high levels of norepinephrine, the microglia became inactive and were unable to respond to local injuries and pulled back from their role in rewiring brain networks.
