Athens, Ga. — Many patients who see physicians for sinus infections expect to be prescribed an antibiotic, but for the majority of them, that course of treatment won't be effective because their infections aren't caused by bacteria. Unfortunately, there aren't great tools to determine which patients will or won't benefit from antibiotics, and the University of Georgia's Dr. Mark Ebell is determined to change that.
A causative gene for a highly common type of hearing loss (sensorineural hearing loss, or SNHL) has been identified by a group of Japanese researchers, who successfully replicated the condition using a transgenic mouse. This discovery could potentially be used to develop new treatments for hearing loss. The findings were published on October 5 in the online version of EMBO Molecular Medicine.
A team of researchers in the Department of Otolaryngology led by Suhrud M. Rajguru, Ph.D., assistant professor of biomedical engineering and otolaryngology, has developed a novel system for delivering therapeutic hypothermia locally to the inner ear in an animal model to conserve residual hearing following cochlear implant surgical trauma. Their approach has the potential to ensure that the sensory structures in the cochlea are left undamaged, enabling patients to benefit from future technologies and therapies.
A Miller School of Medicine research team led by Mustafa Tekin, M.D., a professor in the Dr. John T. MacDonald Foundation Department of Human Genetics who has been exploring the genetics of deafness for more than a decade, has identified a previously unrecognized gene, ROR1 (receptor tyrosine kinase-like orphan receptor 1), that is essential for the development of the inner ear and hearing in humans and mice. Their findings were recently published in PNAS (Proceedings of the National Academy of Sciences).
A laser navigator that complements the white cane and helps visually impaired people to orientate themselves. In Daniel Innala Ahlmark’s doctoral thesis in Industrial Electronics, he presents a unique solution to how visually impaired can find and experience direction and distance to objects in the environment.
The inner ear is no larger than a pencil eraser in circumference and the bones in your ear are the smallest bones in the human body. “They could all fit together on a penny,” said Christine Eubanks, Ph.D., of the VCU Health Department of Audiology. Yet, despite its small size, the ear and hearing plays a large role in social interactions, comprehension and even balance.
Natural selection results in protein sequences that are only soluble to the level that is required to carry out its physiological function. However, in biotechnological applications, we need these proteins to survive concentrations that are up to 1000-fold higher that what naturally occurs, e.g. an antibody drug in the syringe prior to injection.
PHILADELPHIA – A new study from scientists at the Monell Center and collaborators reveals that while foods such as vanilla pudding taste sweeter following three months on a low-sugar diet, the level of sweetness most preferred in foods and beverages does not change. The findings may inform public health efforts to reduce the amount of added sugars that people consume in their diets.
COLUMBIA, Mo. – Vestigial organs, such as the wisdom teeth in humans, are those that have become functionless through the course of evolution. Now, a psychologist at the University of Missouri studying vestigial muscles behind the ears in humans has determined that ancient neural circuits responsible for moving the ears, still may be responsive to sounds that attract our attention. Neuroscientists studying auditory function could use these ancient muscles to study positive emotions and infant hearing deficits.
