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. 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!

The activation of the BER protein cascade starts with DNA damage recognition by glycosylases. Uracil-DNA glycosylase (UDG) is one of the most evolutionary preserved Tandem lesion (cerebrovascular) 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 occlusion of the cervical internal carotid artery and thromboembolic occlusion of the intracranial terminal internal carotid artery or its branches, usually tandem lesion. Approximately 15% of patients undergoing endovascular thrombectomy (EVT) for anterior circulation acute ischemic stroke (AIS) have a tandem lesion (TL), defined as a severe stenosis or occlusion of the cervical internal carotid artery (c-ICA) ipsilateral to its intracranial occlusion.

The patients were categorized into 2 groups with (25 A case series is presented demonstrating a unique approach to the treatment of tandem atherosclerotic lesions of the internal carotid artery. 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. Tandem occlusion is defined by an acute ischemic stroke (AIS) with concomitant steno-occlusive disease of the extra cranial carotid artery and concerned about 10% of AIS patients. Whereas endovascular treatment has shown its efficiency in AIS by large vessel occlusion (LVO), to date, there is no consensus on the endovascular management of the extra cranial carotid artery in tandem occlusion.

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 type of tandem lesion was initially observed in DNA oligomers X-irradiated in solution … Author: Peter Vanacker, MD PhD, Antwerp University Hospital, Belgium.

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 degree of siphon stenosis for patients who underwent endarterectomy ranged from 50% to 90% (mean, 58%), with an ipsilateral ICA stenosis of 60% to 99% (mean, 81%). Two of these 26 patients had relatively minor postoperative complications (Table 2).
