Coronary vasomotion of two stenoses in series (i.e., tandem lesion) was studied in 10 patients with coronary artery disease. Percent area stenosis was 69% 

1'2 One of the problems in the two previous. It is not clear either isolated 60% discrete or 60% tandem lesions can result more severe stenosis. We sought to evaluate the effect of tandem lesion models on  27 Jan 2021 Acute ischemic stroke (AIS) due to tandem lesions (TLs) of extracranial Internal Carotid Artery and Anterior Cerebral Circulation are challenging  Lastly, dOG, dGh, and each dSp diastereomer were synthesized as part of a tandem lesion in a duplex DNA to establish that dOG tandem lesions decrease the  Acute tandem occlusions of the cervical internal carotid artery and an Tandem lesions typically have a worse prognosis than an intracranial lesion alone and  coronary tandem lesions. For in vitro validation, computational flow dynamic modeling of coronary tandem lesion with various degree of stenosis was  Treatment of the extracranial carotid artery in tandem lesions during endovascular treatment of acute ischemic stroke: a systematic review and meta- analysis. In tandem occlusion, the primary cause of symptoms and clinical outcome is thrombus in the intracranial arteries rather than the occlusion of the cervical ICA. Tandem lesion (or tandem occlusion) is a term used in cerebrovascular imaging and intervention to refer to the simultaneous presence of high-grade stenosis or  100. Distal to the lesion.

2008-04-08 · The tandem lesion containing 2-deoxyribonolactone is of particular interest because of the isolated oxidized abasic site’s effects on replication and repair. 2-Deoxyribonolactone is an abasic lesion whose replication in Escherichia coli does not adhere to the A-rule (31, 32). Lesion Length • Lesion length > 20 mm called diffuse. Methods used to measure lesion length are “shoulder-to-shoulder” method vessel narrowed >20%, or Lesion length with >50% narrowing Distance between proximal and distal “angiographically” normal segements “Tandem Lesion” If the gap between lesions < 3 * reference diameter of vessel called Tandem lesion and considered one lesion 2018-09-21 · Tandem occlusion was defined as extracranial ICA lesion (complete occlusion or severe stenosis of ³90% by NASCET criteria, and a proximal intracranial occlusion (distal ICA, and/or M1, and/or M2). 2021-02-04 · The diagnostic accuracy of the QFR in the subgroup with tandem lesions was 93.97% (95% CI 91.29 to 96.02%), which was lower than that of the nontandem lesion group (96.59% 【目的】頭蓋内外主幹動脈病変を有する脳虚血症例（tandem lesions）に対する血管内治療は治療 機器の選択等に工夫を要するため自験例を報告する．【症例】66歳 男性．意識障害（JCS 100） と左片麻痺（MMT 0/5）で発症．National Institute of Health Stroke Scale（NIHSS）31． Tandem lesion was risk factor for endovascular treatment in acute basilar artery occlusion: a single center retrospective observational study Xuan SUN, Feng GAO, Xu TONG, Yi⁃ming DENG, Ning MA, Da⁃peng MO, Li⁃gang SONG, Lian LIU, Xiao⁃chuan HUO, Xiao⁃tong XU, Zhong⁃rong MIAO During the last years, endovascular treatment has evolved as the standard of care for acute ischemic stroke with large vessel occlusions.

Crossing the lesion.

atherectomy catheter captures the power of ultraviolet light to provide a versatile and reliable tool for treating multiple lesion morphologies within PAD lesions.

The repair of tandem carotid lesions has been described using myriad methods, often involving a hybrid approach of stenting with carotid endarterectomy. Because of the worrisome stroke rates associated with this method, we have reported an innovative technique of transcarotid artery revascularization (TCAR) for tandem lesions in a patient with high-grade stenosis of the right common and Tandem lesions are modifications of DNA in which two adjacent nucleotides on the same strand are modified. The exemplar displayed in Fig. 1a, denoted as d(G^T), has adjacent nucleotides linked by a covalent bond between C8 of guanine and the methyl carbon atom of thymine. This 2014-05-31 Tandem Lesions.

8,5‘-Cyclopurine 2‘-deoxynucleosides are among the major lesions in DNA that are formed by attack of hydroxyl radical. These compounds represent a concomitant damage to both sugar and base moieties of the same nucleoside and thus can be considered tandem lesions. Because of the presence of a covalent bond between the sugar and purine moieties, these tandem lesions are not repaired by base Tandem lesions, which are defined as two contiguously, damaged nucleotides in a single DNA strand, are of significant biological interest. The yield of tandem lesions from 1 is much greater than was previously believed. The observations presented could have significant ramifications on how scientists interpret the effects of γ-radiolysis on DNA. For decades, these tandem lesions (TL) had a poor prognosis due to a poor response on intravenous thrombolysis (IVT) alone, with a favorable outcome of only 30% and mortality rates up to 50% (1,2). Recently, endovascular therapy (EVT), where the clot is mechanically extracted through endovascular access, has been proven effective and safe in patients with a LVO of the anterior circulation.

He was found to have double vessel disease: 90% stenosis of the distal left circumflex and tandem lesions in the left anterior descending artery (LAD) with 70% stenosis of the proximal segment and 75% of the distal segment. These compounds represent a concomitant damage to both sugar and base moieties of the same nucleoside and thus can be considered tandem lesions.

The wire-based FFR was performed with an intracoronary injection of 2 mg nicorandil, yielding a value of 0.66 (Figure 1 B). 2019-09-23 · Given these findings, the patient was referred for cardiac catheterization. He was found to have double vessel disease: 90% stenosis of the distal left circumflex and tandem lesions in the left anterior descending artery (LAD) with 70% stenosis of the proximal segment and 75% of the distal segment.

The success and complication rates were evaluated. Tandem mass spectrometry, also known as MS/MS or MS 2, is a technique in instrumental analysis where two or more mass analyzers are coupled together using an additional reaction step to increase their abilities to analyse chemical samples. Tandem MS (or MS/MS, MSn) is a technique to break down selected ions (precursor ions) into fragments (product ions). The fragments then reveal aspects of the chemical structure of the precursor ion. The following scheme explains how Tandem MS works. Reference spectral library searching, while widely used to identify compounds in other areas of mass spectrometry, is not commonly used in glycomics.
