Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, EarlyView.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...

Research and Medical Transcranial Doppler System

Archives of Acoustics, 2016
A new ultrasound digital transcranial Doppler system (digiTDS) is introduced. The digiTDS enables diagnosis of intracranial vessels which are rather difficult to penetrate for standard systems.

Resultados do estudo do Doppler transcraniano em crianças e adolescentes portadores de doença falciforme e correlação entre a velocidade média máxima e características hematológicas: um estudo transversal analítico [PDF]

, 2011
CONTEXT AND OBJECTIVE: Transcranial Doppler (TCD) detects stroke risk among children with sickle cell anemia (SCA). Our aim was to evaluate TCD findings in patients with different sickle cell disease (SCD) genotypes and correlate the time-averaged ...

Feasibility of superimposed supine cycling and lower body negative pressure as an effective means of prolonging exercise tolerance in individuals experiencing persisting post‐concussive symptoms: Preliminary results

Experimental Physiology, EarlyView.
Abstract To examine the feasibility, utility and safety of superimposed lower body negative pressure (LBNP) and tilt during supine cycling in individuals suffering from persisting post‐concussive symptoms (PPCS). Eleven individuals aged 17–31 (6 females/5 males) participated in two randomized separate visits, 1 week apart.

Efficacy of antiplatelet therapy in secondary prevention following lacunar stroke:Pooled analysis of randomized trials [PDF]

, 2015
Background and Purpose: Lacunar stroke accounts for ≈25% of ischemic stroke, but optimal antiplatelet regimen to prevent stroke recurrence remains unclear.

Effects of the angle of head‐down tilt on dynamic cerebral autoregulation during combined exposure to cephalad fluid shift and mild hypercapnia

Experimental Physiology, EarlyView.
Abstract Astronauts experience combined exposure to a cephalad fluid shift and mild hypercapnia during space missions, potentially contributing to health problems. Such combined exposure may weaken dynamic cerebral autoregulation. The magnitude of cephalad fluid shift varies between individuals, and dynamic cerebral autoregulation may be affected more ...

Genetic, laboratory and clinical risk factors in the development of overt ischemic stroke in children with sickle cell disease

Hematology, Transfusion and Cell Therapy, 2018
Cerebrovascular disease, particularly stroke, is one of the most severe clinical complications associated with sickle cell disease and is a significant cause of morbidity in both children and adults.

Detection of impaired cerebral autoregulation improves by increasing arterial blood pressure variability

, 2012
Although the assessment of dynamic cerebral autoregulation (CA) based on measurements of spontaneous fluctuations in arterial blood pressure (ABP) and cerebral blood flow (CBF) is a convenient and much used method, there remains uncertainty about its ...
