Atrial Fibrillation Detected before or after Stroke: Role of Anticoagulation

Flurina Lyrer, Annaelle Zietz, David J. Seiffge, Masatoshi Koga, more

Annals of Neurology > 94 > 1 > 43 - 54

Background Atrial fibrillation (AF) known before ischemic stroke (KAF) has been postulated to be an independent category with a recurrence risk higher than that of AF detected after stroke (AFDAS). However, it is unknown whether this risk difference is confounded by pre‐existing anticoagulation, which is most common in KAF and also indicates a high ischemic stroke recurrence risk. Methods Individual...

Strategy for chemically riveting catenated nitrogen chains

Xianfeng Wei, Ruihao Wang, Min Liu

Journal of Molecular Modeling > 2019 > 25 > 12 > 1-11

Catenated nitrogen chains (CNCs) attract considerable attention because of their structural novelty, their high energy, and their potential as precursors for all-nitrogen materials. However, pure CNCs are unstable under ambient conditions, limiting their on-site or practical applications. Chemical riveting of a CNC involves the maintenance of the structure of a CNC and placing the CNC in a special...

Cerebral lesion correlates of sympathetic cardiovascular activation in multiple sclerosis

Klemens Winder, Ralf A. Linker, Frank Seifert, Ruihao Wang, more

Human Brain Mapping > 40 > 17 > 5083 - 5093

Cardiovascular autonomic dysfunction is common in multiple sclerosis (MS) and contributes significantly to disability. We hypothesized that cerebral MS‐lesions in specific areas of the central autonomic network might account for imbalance of the sympathetic and parasympathetic cardiovascular modulation. Therefore, we used voxel‐based lesion symptom mapping (VLSM) to determine associations between...

Partial pharmacologic blockade shows sympathetic connection between blood pressure and cerebral blood flow velocity fluctuations

Max J. Hilz, Ruihao Wang, Harald Marthol, Mao Liu, more

Journal of the Neurological Sciences > 2016 > 365 > C > 181-187

Cerebral autoregulation (CA) dampens transfer of blood pressure (BP)-fluctuations onto cerebral blood flow velocity (CBFV). Thus, CBFV-oscillations precede BP-oscillations. The phase angle (PA) between sympathetically mediated low-frequency (LF: 0.03–0.15Hz) BP- and CBFV-oscillations is a measure of CA quality. To evaluate whether PA depends on sympathetic modulation, we assessed PA-changes upon sympathetic...

Valsalva maneuver unveils central baroreflex dysfunction with altered blood pressure control in persons with a history of mild traumatic brain injury

Max J. Hilz, Mao Liu, Julia Koehn, Ruihao Wang, more

BMC Neurology > 2016 > 16 > 1 > 1-12

Background Patients with a history of mild TBI (post-mTBI-patients) have an unexplained increase in long-term mortality which might be related to central autonomic dysregulation (CAD). We investigated whether standardized baroreflex-loading, induced by a Valsalva maneuver (VM), unveils CAD in otherwise healthy post-mTBI-patients. Methods In 29 healthy persons (31.3 ± 12.2 years; 9 women) and 25...
