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. BackgroundTo evaluate the acute and long-term results of 'tandem lesion' coronary angioplasty in the left anterior descending artery, and to identify the determinants of restenosis. MethodsA retrospective analysis of clinical, angiographic, and procedure-related variables was caarried out on a consecutive series of 102 patients (mean age 54 years, range 34–71 years; 77% men) who had Tandem lesions of the internal carotid artery and proximal arch branch vessels are uncommon.

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. Tandem lesions were defined as a combination of a relevant extracranial internal carotid artery (ICA) pathology (ipsilateral stenosis >70% or occlusion) and concomitant intracranial large vessel occlusion. Successful reperfusion was defined as modified Thrombolysis in Cerebral Infarction score of 2b-3.

The most common etiology is cervical ICA atherosclerosis, but tandem lesions can also result from cervical ICA dissection. Perhaps the biggest conundrum in the management of tandem lesions is whether or not to stent the cervical ICA in the acute setting. Background Tandem occlusions of the extracranial carotid and intracranial carotid or middle cerebral artery have a particularly poor prognosis without treatment. Several management strategies have been used with no clear consensus recommendations. We examined subjects with tandem occlusions enrolled in the ESCAPE trial and their outcomes. Tandem lesions were defined as a combination of a relevant extracranial internal carotid artery (ICA) pathology (ipsilateral stenosis >70% or occlusion) and concomitant intracranial large vessel occlusion. Successful reperfusion was defined as modified Thrombolysis in Cerebral Infarction score of 2b-3.

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. Because of the presence of a covalent bond between the sugar and purine moieties, these tandem lesions are not repaired by base-excision repair, but by nucleotide-excision repair. Tandem lesions of the internal carotid artery (ICA) and the common carotid artery (CCA) are present in approximately 4.3% of cases.1 Patients with such lesions have to be treated for both stenoses of the extracranial vasculature to avoid either carotid thrombosis following carotid endarterectomy or cerebral embolization from remnant untreated lesions. Between 1994 and 1999 eight patients with tandem lesions of the internal carotid artery were treated by combined carotid endarterectomy for the proximal lesion and intraoperative angioplasty of the distal intracranial lesion via the carotid arteriotomy. The success and complication rates were evaluated.

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. tandem lesions and other products in dna oligomers 435 a tme a2g8 a8 c5 c6 r-t6 l's 2's,2"sb '.11 1170.5 t c6j tme a8 a2 t6,- 1170.3 a8c6 x c6 a2 t6 1sx 1 1 i i i t 1 i i i i 1 1 1 1 Introduction. Tandem occlusions (TOs) involving occlusion of the cervical internal carotid artery (ICA) and concomitant intracranial large-vessel occlusion (LVO) of either the intracranial ICA and/or proximal middle cerebral artery (MCA) have poor response to IV thrombolysis alone,1 and are known to be a predictor of poor outcome after thrombolysis.2 In recent years, endovascular thrombectomy 4- calcified lesions •More risk of: Non dilatable lesion Risk of dissection and perforation Conventional angiography is moderately sensitive for the detection of extensive lesion calcification but is less sensitive for detection of milder degrees of lesion calcification • 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 8,5‘-Cyclopurine 2‘-deoxynucleosides are among the major lesions in DNA that are formed by attack of hydroxyl radical.

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. Building on a study by Cotter and coworkers on analysis of sialylated oligosaccharides using atmospheric pressure-matrix-assisted laser-induced tandem mass spectrometry (MS/MS), we show that library search methods enable the automated Tandem Bagel Company House Made Bagels are our specialty, but we’re so much more than bagels!
