本文讨论了直接检测碳氢的地质和物理背景。在地震波场内,对油气聚集的诊断结果进行了分类,对所观测的地震波场给出了油气聚集效应检测和定量估算的结果。这些方法是以提取原始反射波中若干不同的特征为基础的。本文还给出了影响检测可靠性的因素和油气造成的地震异常解释的准确性因素。结果表明,综合应用不同的波型(P波,S波和转换波)以及钻井资料,在预测碳氢聚集的过程中可增加地震异常解释的准确性。

Single intravenous injection of CoQ<sub>10</sub>reduces infarct size in a rat model of ischemia and reperfusion injury

World Journal of Cardiovascular Diseases 2013年第5期3卷 1-7页

Maintenance of mitochondrial activity and antioxidant features of coenzyme Q10 (CoQ10) could be an effective background for treatment of acute myocardial ischemia. Dietary uptake of CoQ10 is limited to only a few percent. In urgent cases, parenteral administration of CoQ10 could provide fast increase of its plasma and myocardial levels. The aim was to evaluate whether a single intravenous (i.v.) injection of solubilized CoQ10 before ischemia/reperfusion (IR) could lead to replenishment of its myocardial levels and limits subsequent myocardial IR injury. Methods: 30 min prior to coronary artery occlusion rats received i.v. solubilized CoQ10 (30 mg/kg) or saline (1 ml/kg). After 30 min of ischemia and 120 min of reperfusion, infarct zone of left ventricle (Lv) and quantity of CoQ10 in Lv were determined. Cardiac rhythm was monitored through the whole experiment. Results: At the beginning of reperfusion, arrhythmias were recorded in 8 (from 9) in saline and 2 (from 9) in CoQ10-treated rats. Arrhythmias in CoQ10-treated rats arose later (40 ± 8 sec) and had less duration (26 ± 14 sec);14 ± 13 sec and 52 ± 17 sec in saline treated rats respectively. At the end of reperfusion CoQ10 treated rats revealed: 2 fold higher CoQ10 content in Lv (p 10 were accompanied by less infarct size (r = ﹣0.77, p i.v. injection of CoQ10 effectively increased its myocardial levels and protected heart against IR injury by diminishing the size of the irreversibly damaged myocardium, decreasing frequency and duration of arrhythmias. The infarct zone inversely correlated with the quantity of CoQ10 in Lv.

Russian vLBI network "Quasar":Current status and outlook

Geodesy and Geodynamics 2019年第2期10卷 150-156页

作者： N.Shuygina D.ivanov A.Ipatov I.Gayazov D.Marshalov A.Melnikov S.Kurdubov M.vasilyev G.Ilin E.Skurikhina I.Surkis v.Mardyshkin A.Mikhailov A.Salnikov A.vytnov I.Rakhimov A.Dyakov v.Olifirov Institute of Applied Astronomy of the Russian Academy of Sciences

This paper presents the past,present and future status of the Russian vLBI network "Quasar".This network has been developed for at least 20 years by the Institute of Applied Astronomy of the Russian Academy of Sciences(IAA RAS). The equipment installed currently at each "Quasar" station and the facilities for processing observational data are described briefly. The latest results are presented, including the Earth orientation parameters(EOP) determined from the "Quasar" vLBI data and comparison with those from other processing centers. Our future plans to extend the "Quasar" vLB I network to the east and to the west will be carried out by establishing the Ussurijsk station in the Far East and the RussianCuban station in the west. They are considered in the context of the Russian section activity in the GGOS project. The expected improvement of the EOP determination accuracy can be obtained within the future configuration of the "Quasar" network,which is proved by simulation.

Endoscopic ultrasound-guided biliary drainage-current status and future perspectives

Endoscopic retrograde cholangiopancreatography(ERCP)with stenting is the treatment modality of choice for patients with benign and malignant bile duct *** could fail in cases of duodenal obstruction,duodenal diverticulum,ampullary neoplastic infiltration or surgically altered *** these cases percutaneous biliary drainage(PTBD)is traditionally used as a rescue procedure but is related to high morbidity and mortality and lower quality of *** ultrasound-guided biliary drainage(EUS-BD)is a relatively new interventional procedure that arose due to the development of curvilinear echoendoscope and the various endoscopic devices.A large amount of data is already collected that proves its efficacy,safety and ability to replace PTBD in cases of ERCP *** is also possible that EUS-BD could be chosen as a first-line treatment option in some clinical scenarios in the near *** EUS-BD techniques are developed EUS-guided transmural stenting,antegrade stenting and rendezvous technique and can be personalized depending on the individual ***-BD is normally performed in the same session from the same endoscopist in case of ERCP *** lack of training,absence of enough dedicated devices and lack of standardization still makes EUS-BD a difficult and not very popular procedure,which is related to life-threatening adverse *** training models,dedicated devices and guidelines hopefully will make EUS-BD easier,safer and well accepted in the *** paper focuses on the technical aspects of the different EUS-BD procedures,available literature data,advantages,negative aspects and the future perspectives of these modalities.
