In mammalian outer hair cells, the varying receptor potential is converted to active vibrations of the cell body. This mechanical response to electrical signals is termed somatic electromotility; [13] it drives variations in the cell's length, synchronized to the incoming sound signal, and provides mechanical amplification by feedback to the traveling wave.
Viral culture is a laboratory technique [1] in which samples of a virus are placed to different cell lines which the virus being tested for its ability to infect. If the cells show changes, known as cytopathic effects, then the culture is positive.
By MEGAN BARRETO Fears are soaring after NYC got news of a doctor testing positive for Ebola on Thursday. And on top of the diagnosis, it was revealed that 33-year-old Dr. Craig Spencer went ...
Hair is a stratified squamous keratinized epithelium made of multi-layered flat cells whose rope-like filaments provide structure and strength to the hair shaft. The protein called keratin makes up hair and stimulates hair growth. Hair follows a specific growth cycle with three distinct and concurrent phases: anagen, catagen, and telogen. Each ...
Hair cells and supporting cells are both located in the cochlea inside the inner ear. [1] [2] In mammals, hair cells are located in the Organ of Corti and convert energy from sound waves and physical movement into electrical signals. [2] This is accomplished through integrating neurons with hair cells that transmit signals to the auditory nerve ...
Between 5% and 50% of COVID-19 patients experience long COVID, [156] a condition characterised by long-term consequences persisting after the typical convalescence period of the disease.
