The immunostimulatory cytokine IL-12 is able to antagonize immunosuppression induced by solar/ultraviolet (UV) radiation via yet unknown mechanisms. IL-12 was recently found to induce deoxyribonucleic acid (DNA) repair. UV-induced DNA damage is an important molecular trigger for UV-mediated immunosuppression. Thus, we initiated studies into immune restoration by IL-12 to discern whether its eff...

Hapten sensitization through UV-exposed skin induces hapten-specific tolerance which can be adoptively transferred by injecting T cells into naive recipients. The exact phenotype of the regulatory T cells responsible for inhibiting the immune response and their mode of action remain largely unclear. Dectin-2 is a C-type lectin receptor expressed on APCs. It was postulated that dectin-2 interact...

ÖZ E T Bu çalışmada tetrazolyum tuzları ve formazanların yapıları tanımlanmıştır. Ayrıca formazan-tetrazolyum sistemlerinin önemi ve kullanım alanları açıklanmıştır. Formazanların sahip oldukları conjugate p-system kaynaklanan tautomerleşme özellikleri ve geometrik izomerleri incelenmiştir.

Aligned ZnO nanorod arrays films were grown on LiNbO3 substrates by aqueous growth, and subsequently rendered superhydrophobic with RF sputtered coated Teflon. The as-prepared surface exhibits superhydrophobicity with a water contact angle (CA) of 154.5. After 2 hours of UV irradiation on the surface, the surface wettability was approaching hydrophilic state; CA was measured to be 113. This stu...

Degradation of pharmaceuticals in water by TiO2 photocatalysis often suffers from low efficiency due to activity and mass transfer limitation. In this work, diclofenac removal tap was performed on nanotube growth Ti mesh substrate assisted ozone (O3), which generated a hole-arrayed boron-doped diamond (HABDD) film electrode. The vertically oriented nanotubes were used as the heterogeneous photo...

BACKGROUND Environmental cleanliness is one of the contributing factors for surgical site infections in the operating rooms (ORs). To decrease environmental contamination, pulsed xenon ultraviolet (PX-UV), an easy and safe no-touch disinfection system, is employed in several hospital environments. The positive effect of this technology on environmental decontamination has been observed in patie...

Nickel oxide thin film of various preferred orientations was deposited using sol-gel method using solvents including methanol. The resulting film was analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), contact angle measurement, and ultraviolet spectroscopy (UV-vis). Antibacterial activities of nickel oxide-based film against gram-negative bacteria (Escherichia coli) has...

Exposure to ultraviolet radiation is associated with the development of cutaneous carcinomas, and with suppression of immune responses to a variety of antigens, including those of fungal, bacterial and parasitic origin, and contact sensitizers. UV irradiation also influences viral infections. It can affect viral mutation, the photolocalization of viral exanthems, viral oncogenesis, activation o...

This work reports a new method to hydrophobize glass-based micro- and nanofluidic networks. Conventional methods of hydrophobizing glass surfaces often create particulate debris causing clogging especially in shallow nanochannels or require skilful handling. Our novel method employs oxygen plasma, silicone oil and ultraviolet (UV) light. The contact angle of the modified bare glass surface can ...

Microscopic control of macroscopic phenomena is one the core subjects in materials science. Particularly, spatio-temporal material behaviors through a non-contact way fundamental importance but difficult to accomplish. Herein, strategy realize remote luminescence reported. A multi-arm salicylaldehyde benzoylhydrazone-based aggregation-induced emission luminogen (AIEgen)/metal-ion system, which ...
