Preparation of neodymium-doped yttrium aluminum garnet powders and fibers

j.urnal of Rare Earths 2008年第5期26卷 670-673页

作者： R. López j. Zárate E. A. Aguilar j. Muoz-Saldaa Instituto de Investigaciones Metalurgicas UMSNH Morelia Centro de Investigación y de Estudios Avanzados del IPN Unidad Queretaro

Using nitrate precursors, a novel spray-drying assisted citrate gel process for the preparation of neodymium-doped yttrium alumi- num garnet （YAG） phase was developed. Synthesis of single-phase polycrystalline YAG was achieved at temperatures as low as 800 ℃ using the spray-drying methodology whilst conventional approaches currently available require 1000 ℃. Initially, a solution was prepared by mixing aluminum and yttrium nitrates, citric acid, etilenglycol and neodymium oxide. This solution was dried by pulverization （spray dryer） to obtain aggregated precursor powders of the compound. These aggregates were calcined at 800, 850 and 900 ℃ to determine the phase evolution from amorphous to crystalline by X-ray diffraction （XRD）. The morphology of aggregates was characterized by scanning electron microscopy （SEM） and transmission electron microscopy （TEM）. Moreover, through XRD it was determined that the crystallization of YAG phase started at about 800 ℃ without any intermediate phases. The powders were composed of spherical aggregates with an average diameter of 1 um. From these powders, ceramic fibers with additions of 2at.% and 5at.% Nd, were extracted from the melt with diameters ranging from 30 um to 50 um.

Open j.urnal of Anesthesiology 2023年第6期13卷 119-133页

Introduction: The incidence of acute pain after craniotomy differs remarkably in previous studies, and the prevalence of persistent pain is not precisely known. We conducted 6-month follow-up surveys on the incidence and intensity of acute and persistent pain after elective craniotomy. Methods: We carried out a prospective cohort study via a series of structured questionnaires to record acute pain intensity preoperatively and postoperatively, and the incidence of persistent pain 3 and 6 months after a craniotomy in a tertiary care center. Patients scheduled for elective craniotomy were interviewed the day before surgery, postoperatively before discharge from the hospital, and 3 and 6 months after surgery. Pain was assessed on a numeric rating scale (0 - 10) at rest and movement, as well as expectations of pain before surgery, efficacy of pain therapy, and satisfaction with pain treatment. The incidence of adverse events, sleep time and interruptions caused by pain, different pain types, and drugs used for pain treatment were also recorded. Results: A total of 152 patients were enrolled in the study and completed the preoperative questionnaire;123 (81%) completed postoperative questionnaire and 108 (72%) completed the 3- and 6-month follow-ups. The average pain score at the time of the postoperative questionnaire was moderate, 4 at rest and 5 upon movement. The percentage of patients experiencing mild pain at rest and upon movement was 52% and 49%, and moderate pain was 15% and 16%, respectively. Severe postoperative pain was detected in 5% and 8% of patients at rest and upon movement, respectively. Three months after surgery, 6% of patients reported mild pain at rest, 3% moderate pain at rest, and 1% severe pain at rest. Persistent mild and moderate pain at rest after 6 months was reported by 3% and 1% of patients, respectively. The most common adverse events were postoperative nausea and vomiting (11%) and abdominal discomfort (8%). During postoperative pain treatm

作者： j.skelinen j.Korhonen S Voutilainen R 李跃萍 Department of Pediatrics Kuopio University Hospi tal PO Box 1777 70211 Kuopio Finland.Dr

Obj.ctive: To determine whether the CAG repeat length of the androgen receptor (AR) gene contributes to individual differences in the susceptibility to the development of polycystic ovary syndrome (PCOS). Design: Retrospective case- control study. Setting: University- based clinic. Patient(s): One hundred six nondiabetic women with PCOS and 112 nonhirsute fertile controls. Intervention(s): Androgen receptor gene CAG repeat length was analyzed in women with PCOS and their controls. Main Outcome Measure(s): Androgen receptor gene CAG repeat length in both groups. Result(s): The mean CAGn was 21.5 repeats in both groups (NS; t- test). Furthermore, when the CAGn lengths were divided into three categories (CAGn ≤ 18, 19- 24, ≥ 25), the distribution was similar in both groups (NS; χ 2 test). However, all five women carrying ≤ 15 CAG repeats belonged to the PCOS group. In the PCOS group, CAGn did not correlate with body mass index or serum testosterone concentration. Conclusion(s): Androgen receptor CAGn is not a maj.r determinant of PCOS. However, it may be a significant modulator of androgen- related diseases in some individuals.

Interleukin-6 role in head and neck squamous cell carcinoma progression

World j.urnal of Otorhinolaryngology-Head and Neck Surgery 2016年第2期2卷 -页

Interleukin-6 (IL-6) is a pleiotropic cytokine which plays an important role in a num-ber of cellular processes including proliferation, survival, differentiation, migration and inva-sion. IL-6 mediates its downstream effects by activating a number of signaling cascades including j.K/STAT, PI3K/AKT and MAPK pathways. In addition to its effects on tumor cells, IL-6 also regulates tumor progression and tumor metastasis by modulating tumor angiogenesis and tumor lymphangiogenesis. A number of studies have shown that IL-6 levels are markedly upregulated in cancer patients. We and others have shown that high IL-6 expression indepen-dently predicts tumor recurrence, tumor metastasis and poor survival in head and neck cancer patients. Therefore targeting IL-6 signaling is a potential therapeutic strategy for the treat-ment of head and neck squamous cell carcinoma (HNSCC). In this review, we discuss the cur-rent understanding of the role of IL-6 in HNSCC progression and potential therapeutic strategies to target IL-6 signaling for the treatment of head and neck cancer patients.

建立了简便、灵敏地检测烟草中菌核净残留的时间分辨荧光免疫分析方法(TRFIA),及配套的无净化的快速前处理技术。采用镧系元素螯合物Eu-N1标记亲和纯化后的羊抗兔IgG示踪抗体。采用间接竞争TRFIA法建立了菌核净标准抑制曲线,方法的检出限I10为2.0μg/L;抑制终浓度I50为32.00μg/L;检测线性范围为4～128μg/L。考察了丙酮提取后33%,10%和1%的烟草基质对菌核净-TRFIA分析方法的影响,表明在1%烟叶基质条件下,建立的菌核净的抑制曲线的线性范围与标准抑制曲线趋于平行,确定烟草样品的前处理稀释倍数为100倍,计算得到基质影响因子(Im)为17.1。对烟叶样品中添加1,7和24mg/L的菌核净标样,连续3d的添加回收实验表明,方法的回收率为73%～128%,相对标准标准偏差(RSD)在4.3%～13.2%之间;烟草中菌核净的实际最低检出限为1mg/L。本方法可望用于烟草中菌核净残留的快速筛选检测。

Informed Design for Sustainable Growth

创意与设计 2017年第3期 71-80页

作者： Mirj. Kalviainen Noora Nylander Antti Heinonen Design Institute Lahti University of Applied Sciences

Lahti Growth model in the Lahti University of Applied Sciences is j.ining together the regional hub for design competence and the committed development of circular economy solutions. On the strategic level the circular solutions try to prevent waste from occurring in any part of the production and consumption process. This demands also design for user consumer behavior change. New emphasis for design education is required with guiding students in solving this behavior change challenge instead of designing concrete products. The user research for green behavior change reveals practical everyday, social life and interest related hindrances explaining the typical attitude – behavior gap with green actions. From the the user perspective the need is for service thinking based solutions, where the information communication, findability and availability of the offering amongst the everyday activities and interests is essential. This paper presents three into the design education integrated cases that present possibilities of the circular economy design and fulfill some important aspets of the user needs. The information design case for renewable energy production in the countryside developed both static posters and storytelling based animations about the horse manure based energy possibilities. The renewable energy research results data wrangling was integrated with information design ideas and visualisation production. The information design proj.ct produced results for clear, positive, context related and systemic information delivery. It also produced communication messaging about the normality, savings and history related sensibility achieved through recycling and producing renewable energy in the countryside. The second design case was about preowned product recycling possibilities through applying user information and service design process. The cross-disciplinary students' efforts produced finable, positive and without a car available service process, house cleaning
