Current Opinion in Allergy and Clinical Immunology 2008, 8:103–109 Purpose of review There is recognition that respiratory sensitization is an occupational hazard of high concern. Despite international regulatory requirements there is no established protoco for the efficient prospective identification of chemical respiratory sensitizers. We review the predictive behaviour of available methods a...

That hypoxic tissues are more resistant to the effects of radiation than well-oxygenated tissues has been known for many decades, and repeated in vitro demonstrations have confirmed that to achieve the same degree of cytotoxicity, hypoxic cells require about three times the radiation dose that well-oxygenated cells need. Hypoxic cell sensitizers enhance the tissue response to standard radiation...

Photodynamic Control-Mediated Holographic Composites In article number 2100363, Jae-Won Ka and co-workers propose new holographic composites with photodynamic control, composed of photosensitizers, singlet oxygen receptors, polymeric binders. Upon laser irradiation, photoexcited sensitizers generate oxygens, which can be detected by their receptors structural changes. Such changes within the co...

Recently, reactive dyes have attracted a lot of attention for dye-sensitized solar cell applications. This study endeavors to design dye sensitizers with enhanced efficiency photovoltaic cells by modifying the blue 5 (RB 5) and brown 10 10) dyes. Three different strategies were used sensitizers, their was compared using density functional theory (DFT). The optimized geometry, bang gap values, s...
