In the next generation wireless communication systems operating at near terahertz frequencies, dielectric substrates with the lowest possible permittivity and loss factor are becoming essential. In this work, highly porous (98.9% ± 0.1%) and lightweight silica foams (0.025 ± 0.005 g/cm3), that have extremely low relative permittivity (εr = 1.018 ± 0.003 at 300 Ghz) and corresponding loss factor (tan δhz) are synthetized by a template-assisted sol-gel method. After dip-coating the slabs of foams with a thin film of cellulose nanofibers, sufficiently smooth surfaces are obtained, on which it is convenient to deposit electrically conductive planar thin films of metals important for applications in electronics and telecommunication devices. here, micropatterns of Ag thin films are sputtered on the substrates through a shadow mask to demonstrate double split-ring resonator metamaterial structures as radio frequency filters operating in the sub-Thz band.

老年性黄斑变性患者的视力相关生活质量

世界核心医学期刊文摘（眼科学分册） 2005年第7期1卷 8-9页

作者： Berdeaux G.h. Nordmann j.-P. Colin e. Arnould B. 张自峰 Alcon Research 4 rue Henri Sainte Claire Deville 92563 Rueil Malmaison Cedex France

Purpose: To evaluate the relative impact of best and worst eye on vision- related quality of life in patients suffering from age- related macular degeneration (AMD). Design: Quality of life and visual acuity data were collected at baseline during a randomized clinical trial. Methods: setting: Multicenter (11 centers), international study. patients: One hundred fourteen patients with a diagnosis of exudative AMD and primary or recurrent subfoveal neovascular membrane (greatest linear dimension of lesion ≤ 5400 μ m; ≥ 50% of the total lesion was choroidal neovascularization (CNV); classic component of the total CNV ≥ 1.0 mm2). All patients were over age50 years, of any race, either sex. intervention or observation procedure: NeI- VFQ- 39 questionnaire administered to patients at home by trained telephone interviewers. main outcome measures: eTDRS visual acuity (VA) was measured in both eyes separately. Vision- related quality of life (QoL) was assessed using the NeI- VFQ- 39. An analysis of variance was performed on the NeI- VFQ scores, including best eye VA (VA > 20/40 vs VA ≤ 20/40), worst eye VA (VA > 20/200 vs VA ≤ 20/200), and the interaction between the two as independent variables. Results: Best eye VA was 0.34 on average, with VA > 20/40 in 43.0% of patients. Worst eye VA was 0.85 on average, with VA > 20/200 in 32.5% of patients. VA was not linked to general health and ocular pain scores. General Vision, Near Activities, Distance Vision, Driving, Mental health, Role Difficulties, Dependency, Peripheral Vision, and the Global NeI- VFQ scores were affected by both best eye VA and worst eye VA. Conclusion: In the study sample, worst eye VA (≤ 20/200) and best eye VA (≤ 20/40) contributed independently to vision- related QoL. These results suggest that preserving a minimal visual acuity in the worst eye may contribute to vision- related quality of life.

To the editor,During the acute phase of epidermal necrolysis(eN,including Stevens-johnson syndrome and toxic epidermal necrolysis),mucosal lesions involving the tracheo-bronchial tract have been reported[1,2]and approximately one in four eN patients develop acute respiratory failure and require endotracheal intubation and mechanical ventilation(MV)support[3].Asymptomatic respiratory sequelae may be detected on pulmonary function tests after the acute phase in as much as 50%of eN patients,possibly related to pulmonary lesions that occurred at the acute phase[4].

Background:Kaposi’s sarcoma (KS) is a potentially life-threatening multifocal neoplasm. Despite the significant decline in the incidence of acquired immune deficiency syndrome(AIDS)related KS with the use of highly active antiretroviral therapy (hAART), some patients, even those with a good immune restoration, still have aggressive disease. Liposomal anthracyclines or combination chemotherapy are widely used but adverse effects limit their utilization. Objectives:We studied the efficacy and tolerance of docetaxel in the treatment of AIDS-related KS after pretreatment with anthracycline. Patients/methods and main outcome measure:A retrospective cohort study was done. Nine human immunodeficiency virus (hIV)-infected patients were treated from 1997 to 2002 with docetaxel. Tumour response was evaluated using the AIDS Clinical Trial Group (ACTG) staging criteria. Clinical and biological toxicity was evaluated. AIDS status with hIV viral load and CD4T-cell count were measured at the beginning and at the end of the treatment. Results:A major (complete or partial)response and a stabilization of the disease were demonstrated in seven and two patients, respectively. Grade 4 neutropenia and thrombocytopenia were observed in four of nine and one of nine patients, respectively. One patient died after sepsis. Conclusions:Docetaxel has a good and rapid efficacy in anthracycline-pretreated patients with severe AIDS-related KS. Phase II/III trials should be done to compare docetaxel with liposomal anthracyclines as a first-line treatment.

Introduction. Antiphospholipid syndrome may be associated with stroke. Case report. We report a case of a symptomatic occlusion of the innominate artery in a 37- year- old patient, who developed primary anti- phospholipid syndrome. This association, to our knowledge, has not been reported in the literature. Occlusion of the innominate artery was treated by angioplastystenting. effective oral anticoagulation was given to prevent a new thrombotic event. Conclusion. Systematic search for antiphospholipid antibodies is needed as part of the etiology work- up in young stroke victims.

Objective: To assess the effects of focal motor cortex stimulation on motor pe rformance and cortical excitability in patients with Parkinsons disease (PD). Methods: Repetitive transcranial magnetic stimulation (rTMS) was performed on th e left motor cortical area corresponding to the right hand in 12 offdrugpati ents with PD. The effects of subthreshold rTMS applied at 0.5 hz (600 pulses) or at 10 hz (2000 pulses) using a realor a shamcoil were compared to those obtained by a single dose of l dopa. The assessment included a clinical evalua tion by the Unified Parkinsons Disease Rating Scale and timed motor tasks, and a neurophysiological evaluation of cortical excitability by single and paired pulse TMS techniques. Results:RealrTMS at 10 or0.5 hz, but notshamstim ulation, improved motor performance. high frequency rTMS decreased rigidity and bradykinesia in the upper limb contralateral to the stimulation, while low fre quency rTMS reduced upper limb rigidity bilaterally and improved walking. Concom itantly, 10 hzrTMS increased intracortical facilitation, while 0.5 hzrTMS restor ed intracortical inhibition. Conclusions: Low and highfrequency rTMS of the pri mary motor cortex lead to significant but differential changes in patients with PD both on clinical and electrophysiological grounds. The effect s on cortical excitability were opposite to previous observations made in health y subjects, suggesting a reversed balance of cortical excitability in patients w ith PD compared to normals. however, the underlying mechanisms of these changes remain to determine, as well as the relationship with clinical presentation and response to l dopa therapy. Significance: The present study gives some clues to appraise the role of the primary motor cortex in PD. Clinical improvement induc ed by rTMS was too short lasting to consider therapeutic application, but these results support the perspective of the primary motor cortex as a possible targe t for neuromodulation in
