1Photocatalytic degradation of methylene blue by nanostructured Fe/FeS powder under visible light显示文摘The photocatalytic performance of mechano-thermally synthesized Fe/FeS nanostructures formed from micron-sized starting materials was compared with that of a thermally synthesized nanostructure with nano-sized precursors in this paper. The properties of as-synthesized materials were studied by X-ray diffraction(XRD), transmission electron microscopy(TEM), vibrating sample magnetometry(VSM), diffuse reflectance spectroscopy(DRS), and ultraviolet–visible(UV-Vis) spectroscopy. The effects of irradiation time, methylene blue(MB) concentration, catalyst dosage, and p H value upon the degradation of MB were studied. Magnetic properties of the samples showed that both as-synthesized Fe/FeS photocatalysts are magnetically recoverable, eliminating the need for conventional filtration steps. Degradation of 5 ppm of the MB solution by mechano-thermally synthesized Fe/FeS with a photocatalyst dosage of 1 kg/m^3 at pH 11 can reach 96% after 12 ks irradiation under visible light. The photocatalytic efficiency is higher in alkaline solution. The kinetics of photocatalytic degradation in both samples is controlled by a first-order reaction. However, the rate-constant value in the thermally synthesized Fe/FeS photocatalyst sample is only 1.5 times greater than that of the mechano-thermally synthesized one.Hassan Esmaili Amir Kotobi Saeed Sheibani Fereshteh Rashchi 2018International Journal of Minerals,Metallurgy and Materials2018,25,2:11
2Visible light optical coherence tomography measures retinal oxygen metabolic response to systemic oxygenation显示文摘The lack of capability to quantify oxygen metabolism noninvasively impedes both fundamental investigation and clinical diagnosis of a wide spectrum of diseases including all the major blinding diseases such as age-related macular degeneration,diabetic retinopathy,and glaucoma.Using visible light optical coherence tomography(vis-OCT),we demonstrated accurate and robust measurement of retinal oxygen metabolic rate(rMRO2)noninvasively in rat eyes.We continuously monitored the regulatory response of oxygen consumption to a progressive hypoxic challenge.We found that both oxygen delivery,and rMRO2 increased from the highly regulated retinal circulation(RC)under hypoxia,by 0.2860.08 μL min(^-1)(p,0.001),and 0.2060.04 μL min(^-1)(p,0.001)per 100 mmHg systemic pO2 reduction,respectively.The increased oxygen extraction compensated for the deficient oxygen supply from the poorly regulated choroidal circulation.Results from an oxygen diffusion model based on previous oxygen electrode measurements corroborated our in vivo observations.We believe that vis-OCT has the potential to reveal the fundamental role of oxygen metabolism in various retinal diseases.Ji Yi Wenzhong Liu Siyu Chen Vadim Backman Nader Sheibani Christine M.Sorenson Amani A.Fawzi Robert A.Linsenmeier Hao F.Zhang 2015Light(Science & Applications)2015,4,1:8

4一项关于食管静脉曲张出血内镜套扎治疗间隔1周或2周的随机试验显示文摘食管静脉曲张出血套扎治疗恰当的间隔尚不确定。最佳套扎间隔将能使曲张静脉尽快消失以减少早期再出血同时使套扎相关不良事件最少。来自南加州大学凯克医学院的Sheibani S等将急性食管静脉曲张出血以实施套扎治疗的住院患者随机分为间隔1周和2周重复套扎组。同时给予Β受体阻滞剂治疗。套扎按间隔进行,直到曲张静脉根除,根除后3及9个月复查内镜。辛志英 王中峰 Sheibani S 2016临床肝胆病杂志2016,32,6:3
