Protection or Participation?

Children’s status as a particularly vulnerable group in society implies a journalistic obligation to shed light on children’s stories and listen to their perspectives, but their vulnerable position also means they deserve protection from potentially harmful news coverage. Based on a close-reading of two extensively covered news serials concerning irregular migrant children facing deportation, and on in-depth interviews with journalists, editors, and key actors working on behalf of irregular migrant children, the present article sheds light on how journalists balance competing, ethical, professional, and organizational concerns when reporting on issues concerning children. The article shows that while journalists say they are aware of the ethical aspects concerning extensive media exposure of young children, they justify the reporting by foregrounding children as innocent victims of the immigration system and by highlighting the journalistic obligation of shedding light on the wrongdoings of this system. The potential burden of media exposure is relativized as less harmful than the alternative—deportation. Theoretically, the article contributes to the literature on children in the news media, human-interest stories and journalism, and the role of journalism reporting vulnerable groups.

抗人双特异性磷酸酶DUSP18单克隆抗体的制备及鉴定

双特异性磷酸酶（Dual Specificity Phosphatase）是酪氨酸磷酸酶家族中的一员,这个家族中的成员既能对磷酸化酪氨酸去磷酸化,也能对磷酸化丝／苏氨酸去磷酸化．此外,它们还在有丝分裂原激活蛋白磷酸酶信号途径（MAPK）中起重要生理功能．为了制备抗人双特异性磷酸酶的单克隆抗体（mAb）,以DUSP18重组蛋白为抗原免疫BALB／e小鼠,通过B淋巴细胞杂交瘤技术制备抗相应磷酸酶的mAb．用Western blot检测mAb对重组蛋白和细胞中天然磷酸酶的反应性,共获得6株可稳定分泌抗磷酸酶mAb的杂交瘤细胞株,为进一步研究双特异性磷酸酶的去磷酸化作用机理以及其在有丝分裂原激活蛋白磷酸酶信号途径（MAPK）中的信号转导提供强有力的工具．

Evaluation of Serum Vitamin B12 Levels and Its Correlation with Anti-Thyroperoxidase Antibody in Patients with Autoimmune Thyroid Disorders

Vitamin B12 deficiency has been reported in patients with Autoimmune thyroid disorders. However there is limited data on exact prevalence of low B12 and its correlation with anti-thyroperoxidase antibody (anti-TPO) levels in these patients. The aim of our study was to estimate serum vitamin B12 levels in autoimmune thyroid disorders and to correlate B12 levels with anti-TPO. 350 patients were selected by convenient sampling. Vitamin B12 levels and thyroid parameters were estimated using fully automated chemiluminescence method on Access 2. Results of our study shows that using the manufacturer’s cut-off of 145 pg/mL, the prevalence of low serum vitamin B12 was found to be 45.50 %. Higher prevalence (55 %) was seen based on the published cut-off of 200 pg/mL The study however did not demonstrate any significant correlation between vitamin B12 levels and anti-TPO (r = −0.11 and p value of 0.30).

Serum thyroglobulin antibody levels within or near to the reference range may interfere with thyroglobulin measurement

High concentration of thyroglobulin antibodies (TgAb) is a major limiting factor of thyroglobulin measurements in patients with differentiated thyroid cancer. We investigated whether thyroglobulin antibody added to serum samples could interfere with the thyroglobulin assay. Thyroglobulin levels in serum samples with different concentrations of thyroglobulin were measured by electrochemiluminescence immunoassay before and after the addition of increasing concentrations of thyroglobulin antibody using the secondary calibrator solution of the thyroglobulin assay kit containing sheep thyroglobulin antibody to reach thyroglobulin antibody levels within or near to the reference range. Thyroglobulin and thyroglobulin antibody concentrations were also measured in 134 serum samples from 27 patients after thyroid ablation. There was a strong negative association (slope = −1.179) between thyroglobulin antibody and thyroglobulin concentrations in samples with added thyroglobulin antibody (beta = −0.86; P < 0.001). Changes in thyroglobulin concentrations were described mathematically as loss of thyroglobulin% = −0.2408 × Ln(thyroglobulin antibody IU/ml) + 0.1944. Thyroglobulin concentrations were significantly lower than those calculated from experiments with added thyroglobulin antibody in 26/134 samples from patients after thyroid ablation. We conclude that if the same TgAb interference exists in the presence of naturally occurring human TgAb, our observation may prove to be useful during follow-up of patients with differentiated thyroid cancer. However, further studies are needed to explore the clinical relevance of thyroglobulin antibody levels within or near to the reference range in monitoring these patients.     

飞碟双向“快打”技术探讨

射击飞碟双向项目曾是我国拿过奥运会金牌的拳头项目，但随着国际射联不断修改规则增加难，加上我国的飞碟双向缺少一整套先进技术理论的支持，与世界先进水平距离逐渐拉大。要改变现状，迎状赶上，必须实践快打技术，培养“快打型”选手，形成快速、简捷、流畅的技术风格，实践证明：“快打型”技术能更有效地发挥弹丸的效能；有利于克服变化靶、不规则靶的不利因素；有利于射手整体动作程序的完成，防止击发瞬间注意力分散，在实际训练中则要强调人枪结合的质量，将发展速度与提高命中率有效地结合起来，注意发射速度规律性的培养，大胆实践飞碟射击概略瞄准的概念。
