  • Normal balance depends on information from the labyrinth in the inner ear, from other senses such as sight and touch, and from muscle movement. (wikipedia.org)
  • Disruption in the labyrinth, the inner ear organ that controls the balance system, which allows individuals to know where their bodies are in the environment. (wikipedia.org)
  • These hair cells are responsible for sending electrical signals to the brain, which are interpreted as sound. (hearingresearch.org)
  • It s been recognized for a while that these individuals have stronger T-cell immune responses against HIV than other patients, but the reason for that has been unknown, says Xu Yu, MD, of the Ragon Institute and the MGH Department of Medicine, corresponding author of the paper. (regenerativemedicine.net)
  • We have shown that dendritic cells, which play a critical role in generating virus-specific T cells, have an improved ability to recognize HIV and build effective immune responses in elite controllers. (regenerativemedicine.net)
  • Because of this critical role of dendritic cells, the investigators explored the hypothesis that dendritic cells of elite controllers were better able to sense HIV and as a result to generate virus-specific T-cell responses. (regenerativemedicine.net)
  • This contributes to the generation of the more powerful T-cell responses against HIV that are typically observed in elite controllers. (regenerativemedicine.net)
  • Illustration: Cell intrinsic responses against HIV-1 in conventional dendritic cells from Elite Controllers. (regenerativemedicine.net)
  • the hearing aid is able to sufficiently amplify sound to account for the attenuation caused by the conductive component. (wikipedia.org)
  • Earplugs and ear contact area is strictly closed, the amplified sound is leaked from the cracks and returned to the microphone to enlarge to produce the whistle. (earsmate.com)
  • 1) The hand or an object close to the hearing aid, due to a part of the sound-reflecting in your palm or the object and returns to the microphone to further amplified. (earsmate.com)
  • 3) A lot of earwax in the ear, due to the earwax embolism, the amplified sound reflections to the earwax again and to the microphone, can also generate a feedback. (earsmate.com)
  • This trajectory may permit the augmentation of the senses with artificial hearing and sight superior to organic ears and eyes, the direct augmentation of cognition with brain prostheses, and connecting the brain wirelessly to the Internet. (simonlaub.net)
  • Real ear measurements (or probe microphone measurements) are an assessment of the characteristics of hearing aid amplification near the ear drum using a silicone probe tube microphone. (wikipedia.org)
  • After being fit with the devices, Miller used Syracuse Hearing Aid Centers as a front for billing United Healthcare insurance at $3,000 per ear the maximum amount allowed for a hearing aid under the Empire Plan for NY state employees. (a-atlantichearing.com)
  • EVs derived from stem cells have already been shown to help heart cells recover after a heart attack, but exactly how they help and whether the beneficial effect is specific to EVs derived from stem cells has remained a mystery. (regenerativemedicine.net)
  • While this may seem beneficial, it actually works more to the benefit of the virus than the infected individual by allowing HIV to escape recognition by dendritic cells. (regenerativemedicine.net)
  • Of course, the best way to treat a heart attack is to restore blood flow but that process actually may cause more damage to the cells in the heart. (regenerativemedicine.net)
  • The team also found that injured cardiomyocytes that had been treated with EEVs exhibited a set of proteins that was more similar to the uninjured ones compared with untreated cells. (regenerativemedicine.net)
  • They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive. (lookformedical.com)
  • Current research is also pointing towards hearing aids and proper amplification as a treatment for tinnitus, a medical condition which manifests itself as a ringing or buzzing in the ears. (wikipedia.org)
  • In their paper published, the research team reports finding that dendritic cells of elite controllers are better able to detect the presence of HIV paradoxically through a greater susceptibility to HIV infection which enables them to stimulate the generation of T cells specifically targeting the virus.

  • Part of the innate immune system that is the body s first line defense against infection, dendritic cells sense the presence of pathogens in the blood or other tissues, ingest infecting organisms, and then display fragments of the invaders on their surface, which alerts and activates both killer and helper T cells (CD4 and CD8 cells), essentially teaching them to target the specific pathogen. (regenerativemedicine.net)
  • Surprisingly, the team also observed that cells treated with EEVs continued to contract even without oxygen. (regenerativemedicine.net)
  • In most people, HIV infection of dendritic cells appears to be blocked at an early stage, resulting in a lack of HIV DNA and limited viral replication within those cells. (regenerativemedicine.net)
  • The dendritic cells of elite controllers, however, were found to contain higher levels of HIV DNA, probably because of limited expression of a protein called SAMDH1 that usually blocks reverse transcription in several types of immune cells. (regenerativemedicine.net)
  • The heart tissue treated with EEVs had half as many dead cells and had a contractile force four times higher than the untreated tissue after injury. (regenerativemedicine.net)
  • The dendritic cells of elite controllers also appear to produce higher levels of a DNA-sensing protein called cGAS that recognizes the presence of HIV and induces rapid expression of type 1 interferons. (regenerativemedicine.net)
