墨西哥湾勘探最活跃的一些区域是盐下远景区。本文论述的是最著名的发现之一,Mahogany 油田风险勘探中的3D叠前和叠后深度偏移。对叠后偏移,我们采用了陡倾角显式f-x 算法;叠前深度偏移则采用克希霍夫算法。关键性的速度模型最初是用能确定沉积岩速度的 DMO叠加速度建立的。用迭代叠后深度偏移法确定了高速盐岩体。3D叠后深度偏移结果要比原来的时间偏移结果好得多。虽然在叠后偏移剖面上也存在盐下反射波,但3D叠前深度偏移结果更为清晰。在第一次3D叠前深度偏移以后,我们修改速度场,然后再一次做叠前深度偏移。最终的3D叠前深度偏移结果给出了断裂的盐下反射层清晰图象。

Cian Wade及其同事写道,为应对受伤害风险的不公平差异,医疗提供者和卫生系统应该重新构建其在解决不利健康的社会因素方面的作用。卫生不平等正在许多高收入国家扩大,并因为此次新型冠状病毒肺炎(COVID-19)大流行而备受关注14。在许多高收入国家,罹患COVID-19后的患者死亡率中,黑人、西班牙裔、亚裔和其他边缘化族裔群体占比太高,其他因素导致的这些群体的健康结局也都更差5-7。

植酸盐是籽粒和块茎中的普通成分,五十多年前人们就已认识到它能影响钙、磷和镁的利用率,近年来又发现它能影响若干种微量元素的利用率。植酸(六磷酸肌醇)易与钙、镁、钾及微量元素锌、铁和锰等形成络合物和混合盐。它还能与蛋白质络合(Nclson,1967)。植酸盐在植物中的主要作用可能是贮存磷。植酸盐形成于籽实成熟过程中,而在种籽浸泡或发芽时显著减少。

Background: Isolated functional methionine synthase defi-ciency occurs in the cblE and cblG defects of methylcobalamin metabolism and is one of a number of c auses of severely elevated plasma homocysteine. Clinical features are predominan tly of a neurological nature but also include functional restriction of the visual system manifesting as loss of visual acui ty and nystagmus. As yet, the origin and pathogenesis of impaired vision have no t been explained. Materials and methods: We investigated a patientwhowas proven by complementation analysis in cultured fibroblasts to belong to the cblG comple mentation group. Ganzfeld electroretinograms (ERG)-and flash visual evoked pote ntials (VEP) were recorded over a period of 4 years. Results: Amplitudes of all International Society for Clinical Electrophysiology of Vision (ISCEV) standard responses were below normal. The greatest reductions were of rod response to 24 μV, of standard combined response (SC) b-wave to 120 μV, of oscillatory poten tials (OP) to 5 μV, of cone response b-wave to 35 μV, and of 30Hz flicker res ponse to 8 μV. Except for SC and cone a-waves at age 2.5 and 3.5 years, as wel l as cone b-wave at 3.5 years, amplitudes remained at a subnormal level at foll ow-up examinations. Implicit times were slightly prolonged (SC b-wave 6 ms, OP s 2 ms, cone b-wave 2 ms, 30 Hz flicker 4 ms) or fell within the normal range. Responses of the flash VEP were severely deformed but reproducible. Conclusions: This is the first report of detailed investigations of the visual system in a p atient with isolated methionine synthase deficiency. Reduced oscillatory potenti als suggest microvascular damage to the retina through homocysteine. Decreased p hotoreceptor function as well as ganglion cell loss as indicated by pathological flash VEPs may reflect a cytotoxic impact of homocysteine on neurons of the vis ual pathway.

Recently, electromigration （EM） has been extensively known as the fabrication method of nanoscale electrodes with nanometer gaps [1]. EM procedure for the fabrication of nanogaps is particularly simple because the method consists of passing a current through a metal nanowire. However, the nanogaps fabricated by the method tend to exhibit high tunnel resistance. We have already reported that the control of tunnel resistance of the nanogaps is achieved using field-emission-induced EM （so-called "activation"） [2-4], with a voltage source. Activation process is based on moving atoms induced by a fowler.Nordheim （FN） field emission current at the nanogaps. The motion of moving atoms is completely controlled by the field emission current. For instance, 1010～ 11 electrons are required for the motion of "a" Ni atom during the activation with the preset current of approximately 100 μA [4]. However, the process time of a voltage-source-based activation procedure is relatively long for controlling the resistance of the nanogaps. Here, we propose a newly investigated activation procedure with a current source, in order to shorten the process time of the activation.

Background: The impact of chronic hand dermatitis (ChHD) on patient- reported outcomes and economic costs has not been assessed in a US population. Obj.ctive: We sought to evaluate the quality of life, work productivity, activity impairment, and health care costs of patients with ChHD versus those without ChHD. Methods: A 13- item self- assessment questionnaire to identify ChHD was developed and validated. Skindex- 29 and Work Productivity and Activity Impairment questionnaires were used to assess quality of life and work productivity for ChHD. The survey was mailed to a random sample of 1380 members of a Massachusetts managed care organization (N=507, response rate = 36.74% ). Univariate and multivariate analyses were conducted to determine the incremental effect of ChHD on quality of life, work productivity, and activity impairment. Health insurance claims were used to assess medical costs. Results: Quality of life, along with work productivity and activity impairment, were significantly worse for patients with CHD than for those without ChHD; however, there was no significant difference in work time missed. After adj.sting for significant covariates, a 25% cost increase in total medical costs was found attributable to ChHD, which translates to an incremental cost of ＄ 70 per patient per month. Limitations: Survey response rate is not high; the survey respondents may not be completely representative of the nonrespondents. The cost burden of ChHD is underestimated because of the omission of over- the- counter drug and indirect costs. The multivariate models had a low goodness of fit indicated by the low R2 statistics. Conclusions: ChHD has a significant detrimental effect on quality of life,work productivity, activity impairment, and heath care costs. More awareness and treatment of this condition are needed to improve patient outcomes and decrease health care cost.

子宫内膜癌Ⅰ级患者的手术分期

OBj.CTIVE: To examine the impact of surgical staging of patients presenting with grade 1 endometrial cancer. METHODS: The charts of all patients who presented for surgery for endometrial cancer between March 1997 and j.ly 2003 were analyzed for demographic data, final tumor histology, grade, stage, and complications. RESULTS: A total of 349 patients underwent surgical management for endometrial cancer. Preoperatively, 181 (52%) were identified with grade 1 disease, with a mean age of 61 years (range 27-89). Surgical staging (pelvic ±paraaortic lymphadenectomy) was performed in 82%of cases and was omitted only in cases when disease was apparently confined to the endometrium and surgical risk was high. In staged patients, 3.2%had severe surgical complications. There were 2 perioperative mortalities (1 pulmonary emboli and 1 myocardial infarct). In comparison of pre-and postoperative histology, 19%of patients were upgraded, with 15%grade 2, 0.5%grade 3, 2.5%serous or clear cell, and 1%mixed mesodermal tumor. Lymph node metastases were found in 3.9%of patients presenting with grade 1 endometrial cancer, and 10.5%had extrauterine spread (> IIb). High-risk uterine features, including myometrial invasion more than 1/2, grade 3 lesions, high-risk histologic variants, and/or cervical involvement, were found in 26%of the patients. No patients with stage Ia-IIb endometrioid cancer received adj.vant teletherapy or chemotherapy. Four patients with low-risk uterine features were found to have extrauterine disease. Twelve percent of patients received adj.vant therapy, and 17%avoided teletherapy and/or chemotherapy based on surgical staging. CONCLUSION: Surgical staging in patients presenting with grade 1 endometrial cancer significantly impacted postoperative treatment decisions in 29%of patients. Omitting lymphadenectomy in patients presenting with grade 1 endometrial cancer may lead to inappropriate postoperative management.
