Fulminant simultaneous multiple dissections of the cervical and vertebral arteries leading to hemorrhagic and ischemic stroke: A case report.

Background: Intra-and extracranial artery dissections are uncommon but significant causes of ischemic stroke and subarachnoid hemorrhage (SAH). While individual dissections are well-documented, simultaneous dissections of multiple vessels leading to both hemorrhagic and ischemic strokes are extremely rare.

Case Description: A 41-year-old man presented with acute onset of headache, vomiting, and loss of consciousness.

Product release and substrate entry of aldehyde deformylating oxygenase revealed by molecular dynamics simulations.

Cyanobacteria can produce alkanes equivalent to diesel fuels through a two-step enzymatic process involving acyl-(acyl carrier protein) reductase (AAR) and aldehyde deformylating oxygenase (ADO), providing a potential renewable biofuel source. AAR binds to ADO for efficient delivery of an aldehyde substrate and they have been proposed to dissociate when the alkane product is released from the same site as the substrate entrance of ADO. However, the dynamics of the substrate and product in ADO during substrate entry and product release are poorly understood.

Postoperative Time-of-Flight Magnetic Resonance Angiography Classification is a Predictor of Postoperative Recanalization of Unruptured Cerebral Aneurysms.

Background: Endovascular treatment has become the preferred approach for managing unruptured cerebral aneurysms, with simple and balloon-assisted coil embolization as the standard first-line therapy. However, recanalization after coil embolization remains a major clinical concern. This study aimed to evaluate the predictive factors for recanalization using time-of-flight magnetic resonance (TOF-MR) angiography.

Spontaneous disappearance of a small unruptured cerebral aneurysm in the clinoid segment of the internal carotid artery: A case report and literature review.

Background: Various degrees of thrombosis have been reported in patients with giant aneurysms. However, small, unruptured aneurysms rarely resolve spontaneously. Herein, we report a case of a small unruptured aneurysm in the clinoid segment (C3) of the left internal carotid artery (ICA) that showed almost complete occlusion at the 1-year follow-up.

Safety and Efficacy of Management for Intraprocedural Rupture During Endovascular Treatment for Intracranial Aneurysms.

Background And Objectives: Although intraprocedural rupture (IPR) is rare, it is a devastating complication of endovascular treatment (EVT) for intracranial aneurysms. Very few studies have been conducted on IPR, and the safety and efficacy of management techniques of IPR have not been investigated.

Methods: Patients who experienced IPR during EVT between 2013 and 2022 were enrolled from a multicenter observational registry.

Endovascular Treatment for Ruptured Proximal Anterior Cerebral Artery Dissecting Aneurysm: A Case Series.

Subarachnoid hemorrhage due to the A1 segment of an anterior cerebral artery dissecting aneurysm is rare. Therefore, a standard treatment has not been established. Though several case reports of direct surgery exist, there are few reports on endovascular treatment.

Crucial Residue for Tuning Thermal Relaxation Kinetics in the Biliverdin-binding Cyanobacteriochrome Photoreceptor Revealed by Site-saturation Mutagenesis.

Cyanobacteriochromes (CBCRs) are cyanobacterial photoreceptors distantly related to the phytochromes sensing red and far-red light reversibly. Only the cGMP phosphodiesterase/Adenylate cyclase/FhlA (GAF) domain is needed for chromophore incorporation and proper photoconversion. The CBCR GAF domains covalently ligate linear tetrapyrrole chromophores and show reversible photoconversion between two light-absorbing states.

Impact of cancer history on long-term outcome after elective neuro-endovascular treatment in patients aged 80 years or older: A retrospective multicenter observational study.

Aim: Assessing the indication for elective neuro-endovascular treatment (EVT) in older patients requires consideration of the impact of systemic comorbidities on their overall reduced life expectancy. The objective of this study was to determine the long-term outcomes of elective neuro-EVT in patients aged ≥80 years, and to investigate the impact of pre-existing cancer on their long-term outcomes.

Methods: Of the patients enrolled in multicenter observational registry, those aged ≥80 years undergoing elective neuro-EVT between 2011 and 2020 were enrolled.

Mechanical Thrombectomy and Parent Artery Occlusion for Acute Basilar Artery Occlusion Due to Vertebral Fracture and Artery Dissection: A Case Report.

Objective: Basilar artery occlusion (BAO) secondary to traumatic vertebral artery (VA) dissection caused by vertebral fracture is a rare cause of acute ischemic stroke, and optimal management, such as antithrombotic agents, surgical fixation, and parent artery occlusion (PAO), has been controversial. We report a case in which mechanical thrombectomy and PAO were performed for a BAO due to right VA dissection caused by a transverse foramen fracture of the axis vertebra.

Case Presentation: A patient in her 80s suffered from a backward fall, and a neck CT revealed a fracture and dislocation of the right lateral mass of the axis and a compressed transverse foramen.

Introduction of reversible cysteine ligation ability to the biliverdin-binding cyanobacteriochrome photoreceptor.

Cyanobacteriochrome (CBCR) photoreceptors are distantly related to the canonical red/far-red reversible phytochrome photoreceptors. In the case of the CBCRs, only the GAF domain is required for chromophore incorporation and photoconversion. The GAF domains of CBCR are highly diversified into many lineages to sense various colors of light.

P2Y12 reaction units and ischemic and bleeding events after neuro-endovascular treatment.

Background And Purpose: To investigate the associations of perioperative P2Y12 reaction units (PRU) measured using VerifyNow with ischemic and bleeding events, and to determine the PRU threshold in the setting of elective neuro-endovascular treatment (EVT) for intracranial/extracranial vascular disease in patients taking aspirin and clopidogrel.

Methods: Of the patients undergoing elective neuro-EVT while taking aspirin and clopidogrel, those taking both antiplatelet agents for 7 days or more and whose PRU and aspirin reaction units (ARU) were measured were included. The primary and safety outcomes were defined as symptomatic ischemic and major bleeding events within 30 days after EVT.

Endovascular Treatment for Acute Ischemic Stroke After Video-Assisted Thoracoscopic Pulmonary Lobectomy in Patients With Lung Cancer: A Report of Four Cases and Literature Review.

Background: Postoperative cerebral embolic stroke is a serious complication of pulmonary lobectomy, occurring in 1.1% of patients undergoing lobectomy through video-assisted thoracoscopic surgery (VATS). The mechanism of this complication is thought to be embolic stroke caused by thrombus formed due to stagnation in the pulmonary vein stump after VATS lobectomy.

Clinical Course of Abducens Nerve Palsy in Patients with Ruptured Vertebral Artery Dissecting Aneurysms.

Objective: There are few detailed reports on abducens nerve palsy due to a ruptured vertebral artery dissecting aneurysm (VADA). We investigated the clinical characteristics and long-term course of abducens nerve palsy in ruptured VADA patients treated by endovascular surgery.

Methods: Of the 51 cases of ruptured VADA treated by endovascular intervention from 2011 to 2019, 31 with a good/fair outcome, in which ocular motility disorder was able to be followed, were included and investigated.

Periprocedural Variability of Platelet Functions in Carotid Artery Stenting: An Analysis Using VerifyNow.

Objective: The assessment of platelet functions is necessary to prevent both thromboembolic and hemorrhagic complications under dual antiplatelet therapy (DAPT). Using the VerifyNow (Accumetrics, Inc., San Diego, CA, USA) assay, this study aimed to reveal time-dependent changes in platelet functions after carotid artery stenting (CAS).
