X - Rays has become integral and indispensable part of health care diagnosis and intervention. Intervention procedures in Orthopedics surgery now mostly performed under image intensifiers (C-Arm) which involve the risks of occupational overexposure of radiation to the patients and health care personnel. The principles of radiation protection are helpful in keeping radiation exposure just adequate for diagnostic and intervention procedures. Regular surveillance of protective apparel is necessary for longevity of safety. It is responsibility of all OT personnel to know and implement radiation safety. Each situation involving X-ray radiation should include justification of the procedure, minimum radiation exposure just adequate for diagnostic and interventional procedures.

Unlabelled: Melanin pigments block genotoxic agents by positioning on the sun-exposed side of human skin keratinocytes' nucleus. How this position is regulated and its role in genome photoprotection remains unknown. By developing a model of human keratinocytes internalizing extracellular melanin into pigment organelles, we show that keratin 5/14 intermediate filaments mechanically control the 3D perinuclear position of pigments, shielding DNA from photodamage.

Detection of biomolecules, Glutathione (GSH) in particular, is important because it helps assess antioxidant capacity, cellular protection, detoxification processes, and potential disease associations. Monitoring glutathione levels can provide valuable information about overall health and well-being. Many medical disorders have been connected to glutathione levels.

Vegetation productivity and ecosystem carbon sink capacity are significantly influenced by seasonal weather patterns. The time lags between changes in these patterns and ecosystem (including vegetation) responses is a critical aspect in vegetation-climate and ecosystem-climate interactions. These lags can vary considerably due to the spatial heterogeneity of vegetation and ecosystems.

The slope aspect is an important environmental factor, which can indirectly change the acceptable solar radiation of forests. However, the mechanism of how this aspect changes the underground ecosystem and thus affects the growth of aboveground trees is not clear. In this study, Pinus yunnanensis plantation was taken as the research object, and the effects of soil and microbial characteristics on tree growth under different slope aspects and soil depths were systematically analyzed.
