Activation of stress response pathways in the tumor microenvironment can promote the development of cancer. However, little is known about the synergistic tumor promoting effects of stress response pathways simultaneously induced in the tumor microenvironment. Therefore, the purpose of this study was to establish gene expression signatures representing the interaction of pathways deregulated by...

Evidence has recently been presented that photoinhibition of photosystem II (PSII) is triggered by absorption of light by the oxygen-evolving manganese cluster. To get insight into the effects of light on enzymes containing manganese or other transition metal cofactors, the photosensitivities of Mn catalase, Mn superoxide dismutase, the haem (Fe)-containing bovine liver catalase, and CuZn super...

The aim of this work is to investigate the enhancement UVC-based tertiary treatments; for purpose, real wastewater treatment plant (WWTP) effluent was spiked with a model pollutant, namely acetaminophen. UVC irradiation resulted in some photodegradation acetaminophen, which enhanced upon addition hydrogen peroxide (11 mM), but higher amounts oxidizing agent no significant acceleration process. ...

Chlamydomonas reinhardtii is a prospective model system for understanding molecular mechanisms associated with DNA repair in plants and algae. To explore this possibility, we have developed an in vitro repair system from C. reinhardtii cell-free extracts that can efficiently repair UVC damage (Thymine-dimers) in the DNA. We observed that excision repair (ER) synthesis based nucleotide incorpora...

background compact fluorescent lamp (cfl) is a developed fluorescent lamp type designed to saving energy. cfls can cause an increased health risk to humans due to the ultraviolet radiation. objectives the current study aimed to assess the ultraviolet radiation emitted from compact fluorescent lamps in highly used iranian brands. materials and methods this experimental study was conducted on 16 ...

The paper presents two novel realizations of voltage-mode first-order all-pass filters. Both circuits use single universal voltage conveyor (UVC), single capacitor, and two grounded resistors. Using the two NMOS transistors-based realizations of the electronic resistor with two symmetrical power supplies, presented all-pass filter circuits can be easily made electronically tunable. Proposed fil...

This paper describes the architecture of a face recognition technique for door phone embedded system with interactive face and voice response. for the face recognition method using PCA algorithm. In this paper feature is extracted using PCA. The face recognition system using UVC Driver camera has been considered. The proposed system recognize the persons up to 300 cm and send feedback to mobile...

PURPOSE In this study, we investigated the biochemical pharmacology of pirenoxine (PRX) and catalin under in vitro selenite/calcium- and ultraviolet (UV)-induced lens protein turbidity challenges. The systemic effects of catalin were determined using a selenite-induced cataractogenesis rat model. METHODS In vitro cataractogenesis assay systems (including UVB/C photo-oxidation of lens crystall...

We recently found that genes involved in mitochondrial dynamics and autophagy are required for removal of UVC-induced mitochondrial DNA damage. However, drp-1 and pink-1, unlike the autophagy and fusion genes tested, were not necessary for larval development after exposure. We hypothesized that increased fusion resulting from mutations in these genes facilitated recovery of mitochondrial functi...
