"I'm Done": A patient's wish and will to die.

Background: A desire for hastened death is commonly expressed by cancer patients. Although efforts to define and explore this issue have been undertaken, no standardized approach exists to address these desires.

Photocatalytic degradation of organic synthetic dyes and textile dyeing waste water by Al and F co-doped TiO nanoparticles.

Textile wastewater threatens people health by alluring diseases and revealing public existing close to the waste to the dangerous products within. Because waste causes a risk to the environment and people, waste management making is the main challenge of the municipal world. Environmental process such as toxic dye degradation can be stepped up through photochemical process such as visible light induced catalytic degradation.

Visible light assisted photocatalytic degradation of commercial dyes and waste water by Sn-F co-doped titanium dioxide nanoparticles with potential antimicrobial application.

The disintegration of natural water sources signals out the scarcity of adam's ale and will be hurdle for the human physical state. So it is necessary to decrease waste loads and hence pressure on the ecology for the sustainability of fishery and dye industry. Herein, TiO nanoparticles doped with Sn and F are synthesized and the influence of simultaneous doping on the optical, surface morphological, structural, photocatalytic and antibacterial activities are investigated.

Synthesis and characterization of zinc oxide nanostructures and its assessment on enhanced bacterial inhibition and photocatalytic degradation.

In the present study, chemical reaction method is used to synthesis zinc oxide (ZnO) nanostructures concurrently doped with tin and fluorine and investigated for the enhanced bacterial inhibition and photocatalytic degradation. The optical, structural, compositional morphological, photocatalytic and antibacterial activities of ZnO nanostructures by the influence of doping were also studied. The exciton absorption of ZnO spectrum observed at 370 nm is being blue shifted to 364 nm in doped ZnO confirms the increase in incorporation of Sn and F.

Timely Use of Probiotics in Hospitalized Adults Prevents Clostridium difficile Infection: A Systematic Review With Meta-Regression Analysis.

Background & Aims: Systematic reviews have provided evidence for the efficacy of probiotics in preventing Clostridium difficile infection (CDI), but guidelines do not recommend probiotic use for prevention of CDI. We performed an updated systematic review to help guide clinical practice.

Methods: We searched MEDLINE, EMBASE, International Journal of Probiotics and Prebiotics, and The Cochrane Library databases for randomized controlled trials evaluating use of probiotics and CDI in hospitalized adults taking antibiotics.
