Metasurfaces offer a unique playground to tailor the electromagnetic field at subwavelength scale to control polarization,wavefront,and nonlinear *** of the optical response of these structures is challenging due to the nanoscale size of their constitutive elements.A long-sought solution to achieve tunability at the nanoscale is all-optical modulation by exploiting the ultrafast nonlinear response of ***,the nonlinear response of materials is inherently very weak,and,therefore,requires optical excitations with large values of *** show that by properly tuning the equilibrium optical response of a nonlocal metasurface,it is possible to achieve sizable variation of the photoinduced out-ofequilibrium optical response on the picosecond timescale employing fluences smaller than 250μJ∕cm^(2),which is 1 order of magnitude lower than previous studies with comparable reflectivity variations in silicon *** results pave the way to fast devices with large modulation amplitude.

Objective: To examine the seroprevalence, correlates and characteristics of Celiac disease (CD) in a population sample of a Northern Central Area of Italy, by a monocenter retrospective study. Methods: Between 2006 and 2010, serum samples of 9371 subjects (age range 6 months to 91 years) were screened for tissue transglutaminase IgA antibodies (IgA-tTG) by the Immunologia-Allergologia Unit of AUSL1 Massa-Carrara, an area with a population of approximately 150,000. Endomysial IgA antibodies (EMA), HLA typing and small-bowel biopsy were also performed when indicated. Results: Of the 9371 subjects, 269 (2.87%) had positive antibody tests. The population was divided into several age groups and the highest prevalence (5.63%) was found in the 6 months-3 years group. The prevalence of IgA-tTG positivity was double in females compared to males. All IgA-tTG positive patients that were genotyped carried HLA-DQ2 or DQ8, none was a5 positive only. In positive IgA-tTG sera, levels of IgA-tTG were significantly higher in EMA positive than in EMA negative sera (p in children and in adults. Ninety-five/269 IgA-tTG positive subjects underwent biopsy. IgA-tTG levels were different according to the histological degree of the lesion. When EMA were evaluated in IgA-tTG positive subjects the number of EMA negative sera was significantly higher in adults than in children. Conclusions: In summary, this study provides a monocenter retrospective analysis of serological, histological and genetic parameters of subjects with suspicion of CD in an area of Northern Central Italy from 2006 to 2010.

背景与目的通过意大利放射治疗和临床肿瘤学学会(Italian Association of Radiotherapy and Clinical Oncology, AIRO)的一项多中心回顾性研究,明确免疫疗法(immunotherapy, IT)和立体定向放疗(stereotactic radiotherapy,SRT)包括放射外科治疗(radiosurgery, RS)或大分割立体定向放疗(hypofractionated stereotactic radiotherapy, HFSRT)治疗非小细胞肺癌(non-small cell lung cancer, NSCLC)脑转移的疗效和毒性。方法对来自19个意大利中心接受SRT+IT的NSCLC伴脑转移患者进行分析,并与单独接受SRT的对照组患者进行比较。结果共纳入SRT+IT组100例和单独SRT组50例。接受SRT+IT的患者有更长的颅内局部无进展生存期(intracranial local progression-free survival, i LPFS)(经倾向性评分调整后,P=0.007)。在诊断为脑转移时接受IT合并有颅外进展的患者中(n=24),接受SRT后再进行IT与较好的总生存期(overall survival, OS)相关(P=0.037)。多因素分析显示组织学类型为非腺癌、卡氏体能状态(Karnofsky performance status,KPS)评分=70分以及接受HFSRT与显著减少的生存期相关(P值分别为0.019、0.017和0.007)。与SRT和IT治疗间隔>7天(n=10)相比,治疗间隔≤7天(n=90)与更长的OS相关(经倾向性评分调整后,P=0.008)。联合治疗耐受性良好。在放射性坏死方面,接受SRT+IT的患者与单独SRT的患者无显著差异。SRT和IT的治疗间隔对毒性发生率无影响。结论 SRT+IT是一种安全的联合治疗方法,与单独SRT相比,具有更长的i LPFS。
