A Role for GIBBERELLIN 2-OXIDASE6 and Gibberellins in Regulating Nectar Production

Dear Editor The regulation of nectar production is dependent on hormonal signaling. For example, Arabidopsis PIN6, which encodes an auxin efflux transporter family protein, was identified as a nectary-enriched gene whose expression level was positively correlated to total nectar production （Bender et al., 2013）. Furthermore, jasmonic acid （JA） levels peak in Brassica flowers just prior to anthesis and promote nectar secretion （Radhika et al., 2010）. While auxin and JA have been demonstrated to play roles in the regulation of nectar production,

语言通过两种不同的形式可以表达一系列广泛的含义,也就是双系式和旁格式。双系式包含动词(v/V)的投射,常常有句法形态标记(-appl)。旁格式通常以介词短语的形式出现。双系式旁格形式:α动词-applβγα动词γ[介词β]含义:造成领属关系,受益/受害/替代关系,工具;造成移动/移位,刺激,方式,理由有的语言倾向于使用旁格形式(例如英语),有的语言倾向于使用双系式形式(例如伊博语),有的语言可以在两者之间比较自由地转换(例如卢旺达语)。这两种形式之间的句法关系——派生还是不同的中心语投射——存在争议。本文认为汉语的动词短语(vP/VP)属于双系式结构。具体来说,一系列汉语结构(包括双宾语、非典型宾语)都是双系式。我们在larson(2014)的投射理论框架之下提出分析。此理论将题元角色分析成形式化的句法题元特征,题元角色的分配由题元特征之间核查一致关系来实现。我们也讨论了这个分析方法的语义解释,以及它和选择之间的联系。后者与其他轻动词的分析有重要区别。

On the Association between Travel Distance and Treatment Choice for Low-Risk Prostate Cancer: Results from a Rural State

引用

Journal of Cancer Therapy 2016年第9期7卷 656-664页

作者： Chris Hellekson Grant larson Scott Poswilko James Beal Abe Sahmoun J. Kyle Russo The University of North Dakota School of Medicine and Health Sciences Grand Forks ND USA Bismarck Cancer Center Bismarck ND USA

Background: Evidence suggests that cancer patients with increased travel burden to treatment centers may have limited treatment options. Purpose: To investigate the association between travel distance to a treatment facility and initial treatment choice among young men with low-risk prostate cancer in a rural state. Methods: A retrospective medical charts review was conducted of young men (65 years or younger) newly diagnosed with low-risk prostate cancer from January 1, 2005 through December 31, 2014 who were treated with either active surveillance, radical prostatectomy, or brachytherapy at either of the two major hospital systems in Bismarck, ND, USA. Results: Information on a random sample of 242 patients was studied. The majority of patients (66%) received radical prostatectomy. Patients who received radical prostatectomy were significantly younger (p-value 0.001). PSA at diagnosis, clinical stage, and Gleason score were not associated with treatment choice (p-value = 0.06;p-value = 0.1794;and p-value = 1.00;respectively). Adjusting for age at diagnosis, PSA at diagnosis, and treatment facility, treatment choice was not associated with travel distance (p-value = 0.309). Patients treated at St. Alexius facility were more likely to undergo radical prostatectomy than Sanford health patients (p-value Conclusions: We found no association between travel distance and treatment choice for low-risk prostate cancer. Treatment choice was associated with institution which may suggest institutional bias in patterns of care.
