Photocatalytic Degradation of Cr （Ⅵ） and 2-Naphthol in Water Using Sulfur-doped TiO2 Catalyst
, 2015 采用自制的S/Ti O2作为光催化剂,在可见光下进行光催化降解2-萘酚和还原Cr（VI）的实验。考察了S/Ti O2投加量、2-萘酚初始浓度和p H值对2-萘酚降解光催化性能的影响及Cr（VI）~2-萘酚混合体系光催化反应的研究。结果表明：S/Ti O2投加量为2.0 g/L,2-萘酚溶液初始浓度18.75 mg/L,p H值为6~7时2-萘酚光催化降解效果最好;混合体系中的2-萘酚的降解率及Cr（VI）还原率均较相应的单一体系高,Cr（VI）的还原与2-萘酚的氧化之间产生了协同效应。Cr（VI）和2 ...

“Low‐Positive” MOG‐IgG Cases Among Adults With a First Event Suggestive of Multiple Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To determine the prevalence and clinical characteristics of patients with “low‐positive” (LP) MOG‐IgG (titres 1:160–1:320) among adults with a first demyelinating event (FDE) suggestive of multiple sclerosis (MS). Methods From the Barcelona CIS inception cohort, we included adult patients with serum collected ≤ 6 months from the FDE.

Changes in Immune‐Inflammation Status and Prognosis in Pregnancy‐Related Cerebral Venous Thrombosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Distinguishing pathological changes from physiological adaptations in pregnancy‐related cerebral venous thrombosis (CVT) is clinically challenging. This study aimed to characterize coagulation, immune‐inflammation, and dehydration status in these patients and assess their prognostic value.

纳米多孔二氧化钛空心球的水热法制备及其对Cr(Ⅵ)的吸附特性
, 2011 利用水热法一步合成了TiO2.结构、形貌表征结果显示,所得产物为纯相锐钛矿型多孔空心结构,平均粒径为172nm.以此吸附剂对Cr(Ⅵ)的吸附实验结果表明,溶液pH对TiO2吸附性能影响显著,在pH为2.7时,产物最大吸附率为86%,随pH值升高,吸附率逐渐降低.其等温吸附行为很好地符合朗缪尔单分子层吸附模型,通过计算得到产物对Cr(Ⅵ)的理论最大单位吸附量为23mg/g.产物吸附Cr(Ⅵ)后,使用碱液可将吸附的Cr(Ⅵ)离子脱附,表现出了极好的重复使用性能.Cr(Ⅲ)共存对TiO2的Cr(Ⅵ ...

From Adult to Adolescent: Alignment in Clinical Trials and Outcomes in Axial Spondyloarthritis
Arthritis Care &Research, EarlyView.Spondyloarthritis (SpA) is a group of chronic inflammatory diseases encompassing axial and peripheral forms, with up to 20% of patients developing symptoms before age 16. Despite this substantial pediatric burden, treatment options for juvenile‐onset SpA (JSpA), particularly those with axial disease (axJSpA), remain limited.
