Open Journal of Preventive Medicine 2014年第2期4卷 78-89页

作者： Hind A. beydoun Suraj Khanal May A. beydoun Alan B.

Despite the existence of colorectal cancer (CRC) screening guidelines, population-based studies have consistently shown under-utilization of CRC screening procedures among older adults in the United States. We examined whether symptoms of anxiety and depression are associated with colorectal cancer (CRC) screening perceptions and behaviors among older adults in a primary care setting. A cross-sectional study was conducted by using a sample of 143 family medicine patients who completed an 88-item anonymous self-administered questionnaire covering symptoms of anxiety and depression as well as CRC screening perceptions (defined based on the Health Belief Model) and behaviors (defined as ever use of or adherence to CRC testing). Moderate-to-clinically significant anxiety and depressive symptoms were, respectively, prevalent in 47% and 42% of participants. Perceived benefits and barriers were the only Health Belief Model constructs associated with anxiety. Perceived barriers were positively associated with anxiety symptoms after adjustment for confounders, including age, gender, race/ ethnicity, marital status, education, smoking history, body mass index and self-rated health. By contrast, perceived benefits were negatively associated with anxiety symptoms only in the unadjusted model. Neither anxiety nor depression was associated with ever use of or adherence to CRC testing. Symptoms of anxiety, but not depression, may potentially influence CRC screening perceptions, with implications for behavioral interventions targeting CRC testing.

目的对有关7种用以治疗儿童和成人新诊断部分性和全身性癫癎的新型抗癫癎药物(AEDs):加巴喷丁(gabapentin,GBP)、拉莫三嗪(lamotrigine,LTG)、托吡酯(topiramate,TPM)、噻加宾(tiagabine,TGB)、奥卡西平(oxcarbazepine,OXC)、左乙拉西坦(levetiracetam,LEV)和唑尼沙胺(zonisamide,ZNS)的药力(efficacy)、耐受性和安全性按序进行评估(这些药物已受到美国食品与药品管理局FDA的批准)。方法由23位成人神经病学家、儿科神经病学家、癫癎病学家及药理学家组成的,依据从1987年到2002年9月Medline,Current Contents和Cochrane上发表的相关文献和2003年以前的指南提供的证据进行专家组循证医学评估。结果有证据通过对照试验或剂量控制试验显示:加巴喷丁、拉莫三嗪、托吡酯和奥卡西平单药治疗对新诊断的青少年和成人部分性或混合性癫癎是有效的。亦有证据显示,拉莫三嗪对于新诊断的儿童失神发作有效。但尚缺乏证据证明新型抗癫癎药物对新诊断的其他类型的全身性癫癎综合征是否有效。结论循证医学评估结果提供了新诊断癫癎患者的抗癫癎药物应用指南,但尚需更多的证据用以鉴定其在癫癎的类型或综合征中的疗效。

勘探专家们已经认识到S波在反射图象中表现为噪声。声波技术过去或现在都是为了考虑计算速度或因资料不全(即只有垂直分量的资料)而使用的。这里,我们介绍一种弹性反演技术.并且在礁勘探上说明了它的应用。由于资料中存在大量转换波,有偏VSP是需要弹性反演技术的极好例证。弹性反演技术也需要有好的横波速度。结果说明再作进一步的少量尝试是值得的。在所提出的例子中,我们开始看到礁体内的一些细节,而地面反射资料和VSP常规处理仅仅显示了盐B与碳酸盐A_2分界面上的特征。这个分界面并不是储层,而仅是与储层大致有关的。

为什么阿拉伯板块的油气如此丰富而多产?

国外油气勘探 2000年第1期12卷 1-10,62页

作者： ZiadR.beydoun 徐金林杨卫东王萍

截止到1998年初,阿拉伯板块(大致包括阿拉伯半岛,富饶的伊斯兰国家和土耳其东南部及Taurus/Zagrog山脉南侧的伊朗西南部)的油和气的储量分别占全球油和气储量的66.4%和33.9%。其中98%以上的储量分布在从伊拉克到阿曼之间的阿拉伯大陆架... 详细信息

截止到1998年初,阿拉伯板块(大致包括阿拉伯半岛,富饶的伊斯兰国家和土耳其东南部及Taurus/Zagrog山脉南侧的伊朗西南部)的油和气的储量分别占全球油和气储量的66.4%和33.9%。其中98%以上的储量分布在从伊拉克到阿曼之间的阿拉伯大陆架东北边缘。本文分析了该区油气富集的原因。其中部分因素包括在不同地质年代地层中广泛存在着多套成油体系(包括生油岩广泛而多层系的分布)、碳酸盐岩与砂岩储层的相互并存、大型背斜圈闭和长期稳定的沉积。而最主要的一点是它有无可比拟的宽广的北东向大陆架——宽度近2000km,长度近3000km。有人提议设立一项研究与发展基金,目的是开发一种或多种能够替代石油的能源产品。因为按目前的能源消耗水平估算,石油这种有限的珍贵资源(石化工业的原料,合成蛋白质的来源)将在43年内归于枯竭。
