Thin film of zinc oxide was prepared by spin coating on pyrex glass using zinc acetate dehydrate, 2-methoxyethanol and monoethanolamine (MEA) as a precursor, solvent and stabilizer respectively. Also, Aluminium-doped thin film of ZnO was prepared by using AlCl3. Deposited thin films were investigated for structural and optical properties using X-ray diffraction (XRD) and UV–VIS-NIR spectrophoto...

Many workers perform their daily activities outdoors and many anatomical body sites are exposed to UV radiation. The effects of solar radiation on human health depend on the amount and type of radiation impinging on the body. This paper aims to investigate and analyse the diurnal UV radiation exposure at typical anatomical site for farm workers. The diurnal distribution in solar UV exposure at ...

As a critical ubiquitin ligase, the anaphase-promoting complex/cyclosome (APC/C) governs cell cycle progression, signaling modulation and the pathogenesis of some human diseases. Recent studies implicate APC in maintaining genomic integrity, but the mechanism by which it plays such a role remains largely unknown. We report here that acute UV radiation triggers proteolysis of CDH1, an activator ...

The carcinogenic activity of solar radiation has been known for nearly a century. However, within the past few years, we have realized that exposing the skin to sunlight also has profound immunological effects on the host and that these immunological changes can contribute to the development of skin cancer and alter host resistance to infectious diseases. These findings have led to the developm...

Current conditions of 2–11 kJ m day of UV-B radiation and temperatures of >308C during flowering in cotton cultivated regions are projected to increase in the future. A controlled environment study was conducted in sunlit growth chambers to determine the effects of UV-B radiation and temperature on physiology, growth, development and leaf hyperspectral reflectance of cotton. Plants were grown i...

background : farmers and welders who work in open spaces and are exposed to direct sunlight are often exposed to sunlight radiation o n the neck and head . thus, they may be afflicted with various types of skin cancer . the aim of the present study was to investigate the amount of uv exposure in welders working in shahrud city , iran .   materials and method s : this cross-sectional , descripti...

[1] The interest in solar ultraviolet (UV) radiation from the scientific community and the general population has risen significantly in recent years because of the link between increased UV levels at the Earth’s surface and depletion of ozone in the stratosphere. As a consequence of recent research, UV radiation climatologies have been developed, and effects of some atmospheric constituents (s...

Microarray hybridization was used to assess acclimation responses to four UV regimes by near isogenic maize (Zea mays) lines varying in flavonoid content. We found that 355 of the 2,500 cDNAs tested were regulated by UV radiation in at least one genotype. Among these, 232 transcripts are assigned putative functions, whereas 123 encode unknown proteins. UV-B increased expression of stress respon...
