Summary
Traffic police in India often suffer from noise-induced hearing loss (NIHL). Smartphone audiometry effectively detected hearing loss in 80 out of 88 officers, highlighting a viable screening tool.
Area of Science:
- Occupational Health
- Audiology
- Public Health
Background:
- Noise-induced hearing loss (NIHL) is a significant occupational hazard, particularly affecting traffic police.
- Access to audiology services is limited in developing countries like India due to resource constraints.
Purpose of the Study:
- To assess hearing thresholds in traffic police using smartphone-based audiometry.
- To evaluate the prevalence of noise-induced hearing loss in this occupational group.
Main Methods:
- An occupational history was collected from 88 traffic police personnel.
- Smartphone-based audiometry (Hearing Test TM software) was performed to measure hearing thresholds.
- Analysis included categorizing hearing loss severity and identifying patterns like the 4000/6000 Hz notch.
Main Results:
- 80 out of 88 participants exhibited increased hearing thresholds indicative of NIHL.
- Prevalence included 8 normal, 24 mild, 42 moderate, and 14 severe hearing loss cases.
- A characteristic NIHL pattern (notch at 4000/6000 Hz) was observed in 28 individuals.
Conclusions:
- Smartphone audiometry is a practical and effective tool for early detection of hearing loss in traffic police.
- This technology can help bridge the gap in audiology service accessibility in resource-limited settings.
- Early diagnosis through mobile health applications can improve management of occupational hearing impairment.

The ER, Golgi apparatus, endosomes, and lysosomes work in tandem to modify, sort, and package proteins and lipids. An integrated membrane trafficking network facilitates the back and forth shuttling of molecules within different organelles in the same cell or across the cell membrane.
The transport of soluble and membrane proteins is mediated by transport vesicles that collect cargo from one cellular compartment and deliver it to another by fusing with the target organelle membrane. The Rab...

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

48.4K
In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially and so are classified as weak bases. These types of compounds are also abundant in nature and important commodities in various technologies. For example, global production of the weak base ammonia is typically well over 100 metric tons annually, being widely used as an agricultural fertilizer, a raw material for chemical synthesis of other...

01:54Base Excision Repair
26.4K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

Salts with Acidic Ions
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:
