Summary
Fuchs corneal dystrophy (FCD) is linked to hearing loss. Patients with FCD showed worse hearing at low frequencies and better hearing at high frequencies compared to controls.
Area of Science:
- Ophthalmology
- Audiology
- Genetics
Background:
- Fuchs corneal dystrophy (FCD) is primarily an eye condition.
- Some genetic links between FCD and hearing loss have been suggested.
- The relationship between FCD and hearing impairment remains unclear.
Purpose of the Study:
- To investigate the association between Fuchs corneal dystrophy and hearing loss.
- To compare audiometric thresholds in FCD patients versus population controls.
Main Methods:
- A case-control study design was employed.
- 180 FCD patients were compared with 2,575 population-based controls from NHANES (2005-2010).
- Pure-tone audiometry and generalized estimating equations were used for analysis, adjusting for covariates.
Main Results:
- FCD patients exhibited significantly higher hearing thresholds (poorer hearing) at low frequencies (0.5 kHz).
- FCD patients demonstrated significantly lower hearing thresholds (better hearing) at high frequencies (4 kHz).
Conclusions:
- This study provides objective evidence linking Fuchs corneal dystrophy with distinct patterns of hearing loss.
- FCD is associated with poorer low-frequency and better high-frequency hearing compared to controls.
- Further research is warranted to elucidate the underlying mechanisms of this association.

01:21Pilot and Numeric Relaying
492
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

01:21Satellite Stem Cells and Muscular Dystrophy
2.4K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

17.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

1.4K
Microorganisms exhibit diverse oxygen requirements and growth patterns driven by their metabolic strategies and environmental adaptations. Oxygen, while essential for many organisms, can also be toxic under certain conditions, shaping how microorganisms grow and survive.Oxygen Requirements of MicroorganismsMicroorganisms are classified based on their ability to use or tolerate oxygen:● Obligate aerobes like Mycobacterium tuberculosis need oxygen for energy production, as it serves as the...

6.9K
When protons A and X are coupled, their nuclear spin energy levels are slightly modified. This is because the energy required to excite proton A to a spin state parallel to proton X is slightly different from the energy required for it to become anti-parallel to spin X. Consequently, there are two possible excitation frequencies for A (A1 and A2), depending on the spin state of X, and vice versa. The mutual nature of coupling implies that the difference between frequencies A1 and A2, indicated...
