2007年，我们发起了一个主动地震和被动地震的地震学实验，实验地点是Bear岛附近的巴伦支海大陆边缘、Mohns海岭和Knipovich海岭之间的结合部和大西洋东北部的扩张轴。2007～2008年间的野外实验主要是安装几台地震仪器，实施相关的野外操作。这项研究的目标是大陆边缘沉积盖层至上地幔的地球结构和动力学机制，因为该大陆边缘包含一个非常厚的沉积楔和至少一个古断裂带。

Acute coronary syndrome in a patient with a single coronary artery arising from the right sinus of Valsalva

World Journal of Cardiology 2012年第8期4卷 264-266页

Coronary artery anomalies are usually encountered as coincidental findings during coronary angiography or at autopsy. Life threatening symptoms, such as arrhythmias, syncope, myocardial infarction, or sudden death, can occur in up to 20% of patients. However, the majority of anomalies (80%) are benign and asymptomatic. A single coronary artery (SCA) is one of the most rarely seen coronary anomalies with an incidence of 0.05%. We report the case of a 55-year old male patient who presented with symptoms of chest pain associated with an acute myocardial infarction. Coronary angiography revealed an anomalous left main coronary artery (LMCA) originating from the right coronary ostium, and an occluded distal right coronary artery. The occluded distal right coronary artery was successfully treated by thrombosuction and stenting. In order to confirm the origin and course of the SCA, multi-slice computed tomography (MSCT) of the heart was performed after coronary angiography. MSCT showed that the anomalous LMCA originated from the right coronary artery ostium and then passed the interventricular septum, instead of being intra arterial, and under the right ventricular infundibulum. The anomalous LMCA was classified as R-II S subtype according to Lipton’s classification.

A 52-year-old white woman had suffered from intermittent gastrointestinal (GI) bleeding for one year. Upper GI endoscopy, colonoscopy and peroral doubleballoon enteroscopy (DBE) did not detect any bleeding sour ce, suggesting obscure GI bleeding. However, in video capsule endoscopy a jejunal ulceration without blee ding signs was suspected and this was endoscopically conf irmed by another peroral DBE. After transfusion of packed red blood cells, the patient was discharged from our hospital in good general *** weeks later she was readmitted because of another episode of acute bleeding. Multi-detector row computed tomography with 3D reconstruction was performed revealing a jejunal tumor causing lower gastrointestinal bleeding. The patient underwent exploratory laparotomy with partial jejunal resection and end-to-end jejunostomy for reconstruction. Histological examination of the specimen confirmed the diagnosis of a low risk gastrointestinal stromal tumor (GIST). Nine days after surgery the patient was discharged in good health. No signs of gastrointestinal rebleeding occurred in a followup of eight months. We herein describe the comp lex presentation and course of this patient with GIST and also review the current approach to treatm ent.

Background There is no recent epidemiological data on HIV infection in Gabon,particularly in pregnant *** close this gap,an HIV-prevalence survey was conducted among Gabonese pregnant women,followed by a cross-sectional case-control study in which the prevalence of various co-infections was compared between HIV-positive and HIV-negative pregnant *** Between 2018 and 2019,data for the HIV-prevalence survey were collected retrospectively in 21 Gabonese antenatal care centres(ANCs).Subsequently,for the prospective co-infection study,all HIV-positive pregnant women were recruited who frequented the ANC in Lambarénéand a comparator sub-sample of HIV-negative pregnant women was recruited;these activities were performed from February 2019 to February *** mean number of coinfections was ascertained and compared between HIV-positive and HIV-negative ***,the odds for being co-infected with at least one co-infection was evaluated and compared between HIV-positive and HIV-negative *** HIV-positivity was 3.9%(646/16,417)among pregnant women.183 pregnant women were recruited in the co-infection study.63%of HIV-positive and 75%of HIV-negative pregnant women had at least one *** was a trend indicating that HIV-negative women were more often co-infected with sexually transmitted infections(STIs)than HIV-positive women[mean(standard deviation,SD):2.59(1.04)vs 2.16(1.35),respectively;P=0.056];this was not the case for vector-borne infections[mean(SD):0.47(0.72)vs 0.43(0.63),respectively;P=0.59].Conclusions Counterintuitively,the crude odds for concomitant STIs was lower in HIV-positive than in HIV-negative *** change of magnitude from the crude to adjustedOR is indicative for a differential sexual risk factor profile among HIV-positive and HIV-negative women in this *** might potentially be explained by the availability of sexual health care counselling for HIV-positive women within the framework of the nati
