This work reports the design and functionalization of new composite-based polyethylene terephthalate (PET) fibers with high anti UV radiation. Polyethylene terephthalate fibrous nonwovens were coated by materials oxides (MOx) like titanium dioxide (TiO2), zinc oxide (ZnO) and silicon dioxide (SiO2). Chitosan (CT) and polyvinylidene fluoride (PVDF) ...

Plant glandular trichomes (GTs) are adaptive epidermal structures that synthesize and accumulate diverse specialized metabolites well-known as defense chemicals against biotic attacks, but their roles against abiotic challenges including UV radiation and cold climates remain largely unexplored. Colquhounia vestita Wall is a Chinese-Himalayan Lamiac...

The terrestrial green algal members of the genera Interfilum and Klebsormidium (Klebsormidiophyceae, Streptophyta) are found in biological soil crusts of extreme habitats around the world where they are regularly exposed, among other abiotic stress factors, to high levels of ultraviolet radiation (UVR). As a consequence those species synthesize and...

Antibiotics are resistant to biodegradation, and their removal by biological processes is difficult. The purpose of this study was to investigate the removal of azithromycin from water using ultraviolet radiation (UV), Fe (VI) oxidation process and ZnO nanoparticles. The effect of different parameters such as pH, temperature, hydraulic retention ti...

Baculoviruses have been developed as long-term and environmentally friendly biopesticides. However, solar ultraviolet radiation can reduce the activity of baculovirus. Radiation sensitive 23 (Rad23) can recognize DNA damage and is involved with nucleotide excision repair (NER). In the current study, BmRad23 was accumulated mainly within the nucleus...

Direct exposure to Ultraviolet (UV) radiation causes progressive damages in retinal cells, which is one of the hypothetical mechanisms underlying age-related retinopathy or macular degeneration. The protective effects of Apocynin against UV damages were firstly tested in retinal pigment epithelium cells (RPEs) and retinal ganglion cells (RGCs). Sub...
Abstract Ferricyanide Fe(CN) 6 3- is one of the most stable cyanometallic complexes present in the gold mining effluents. This cyanocomplex is hard to degrade by natural attenuation and generates a negative impact on aquatic environments. Although free cyanide (CN-) can be obtained by acidifying the solution, the CN- is lethal for all forms of life...

Among abiotic stresses, both drought and UV-B radiation effectively trigger the accumulation of secondary metabolites, and can be widely applied in plant factories. The objectives of this study were to investigate antioxidant accumulation under drought stress alone, or in combination with UV-B radiation near harvest, and to determine an optimal tre...

Aging is a major cause of many degenerative diseases. The most intuitive consequence of aging is mainly manifested on the skin, resulting in cumulative changes in skin structure, function and appearance, such as increased wrinkles, laxity, elastosis, telangiectasia, and aberrant pigmentation of the skin. Unlike other organs of the human body, skin ...

Plants commonly respond to UV radiation through the accumulation of flavonoids and related phenolic compounds which potentially ameliorate UV-damage to crucial internal structures. However, the seasonal dynamics of leaf flavonoids corresponding to epidermal UV absorbance is highly variable in nature, and it remains uncertain how environmental facto...
