Human Health is Affected by Noise Pollution
Abstract: Noise pollution has a substantial negative impact on human health. Long-term exposure to loud noises can cause stress, hearing loss, sleep disruptions, and cardiovascular problems, among other health problems. Noise decreases productivity and hinders cognitive function by making it difficult to focus and communicate. It may also result in agitation, worry, and even help develop mental health issues. To lessen the negative impacts of noise pollution on human well-being, adequate …

Protein Peroxidation: The Covalent Modification of Protein Induced Through Reactive Oxygen Species (ROS) and With Secondary By-products of Oxidative Stress.
Abstract: The abundance in biological system and high reaction rate constant are making the proteins as major targets for radicals and two-electron oxidants in biological systems. The multiple side-chain and backbone sites are susceptible for highly reactive radical damage. Less reactive species exhibit greater selectivity with reference to the residues targeted and their spatial location. Modified structure may result in the increased side-chain hydrophilicity, side-chain fragmentation and backbone fragmentation, aggregation through …
