Effect of benzoyl taurine dipotassium salt on coagulation, hemostasis and vascular activity in the microvasculature of the brain in violation of cerebral circulation

Сибирский научный медицинский журнал, 2022
Cerebral circulation disorders (CCD) are one of the most common causes of mortality and disability in the population. Improving the microcirculation of brain tissue is one of the main directions in the treatment and prevention of CCD.Aim of the study was

Autoregulation of Cerebral Blood Flow During 3-h Continuous Cardiopulmonary Resuscitation at 27°C

Frontiers in Physiology, 2022
Introduction: Victims of accidental hypothermia in hypothermic cardiac arrest (HCA) may survive with favorable neurologic outcome if early and continuous prehospital cardiopulmonary resuscitation (CPR) is started and continued during evacuation and ...

Anatomical atlas of the upper part of the human head for electroencephalography and bioimpedance applications [PDF]

, 2021
Volume conductor problems in cerebral electrophysiology and bioimpedance do not have analytical solutions for nontrivial geometries and require a 3D model of the head and its electrical properties for solving the associated PDEs numerically. Ideally, the model should be made with patient-specific information.

Critical appraisal on mitochondrial dysfunction in Alzheimer’s disease

AGING MEDICINE, Volume 5, Issue 4, Page 272-280, December 2022., 2022
Amyloid plaques deposit on neurons in case of Alzheimer's Disease. Mitochondria play a vital role in pathogenesis of Alzheimer's Disease. Mitochondrial dysfunction can lead to formation of mPTP, alteration of complexes 1,3 and 4, deficits in bioenergetics with impaired mitochondrial biogenesis. Abstract It is widely recognized that Alzheimer's disease (

Intracranial collateral circulation and its role in neurovascular pathology

Egyptian Journal of Neurosurgery, 2021
Background Collateral circulation is a vascular network which maintains the blood flow after the partial blockage of primary vascular pathways. This acts as potential vascular supplementary system and plays important role in the cerebral ischemia.

Higher ventricular rate during atrial fibrillation relates to increased cerebral hypoperfusions and hypertensive events [PDF]

Scientific Reports, 9: 3779, 2019, 2019
Atrial fibrillation (AF) is associated with cognitive impairment/dementia, independently of clinical cerebrovascular events (stroke/TIA). One of the plausible mechanisms is the occurrence of AF-induced transient critical hemodynamic events; however, it is presently unknown, if ventricular response rate during AF may impact on cerebral hemodynamics.

A pilot randomized controlled trial of WeiNaoKang (SaiLuoTong) in treating vascular dementia

AGING MEDICINE, Volume 5, Issue 4, Page 246-256, December 2022., 2022
A 16‐week randomized double‐blind, placebo‐controlled trial for vascular dementia was carried out with WeiNaoKang (or SaiLuoTong). There were significant differences in improvement in cognitive function and activities of daily living, favouring the treatment group.

Transient cerebral hypoperfusion and hypertensive events during atrial fibrillation: a plausible mechanism for cognitive impairment [PDF]

Scientific Reports, 6: 28635, 2016, 2016
Atrial fibrillation (AF) is associated with an increased risk of dementia and cognitive decline, independent of strokes. Several mechanisms have been proposed to explain this association, but altered cerebral blood flow dynamics during AF has been poorly investigated: in particular, it is unknown how AF influences hemodynamic parameters of the distal ...
