Removal of the skin blood flow artifact in functional near-infrared spectroscopic imaging data through independent component analysis [PDF]

Journal of Biomedical Optics, 2007
We investigate whether the functional near-infrared spectroscopic (fNIRS) signal includes a signal from the changing skin blood flow. During a locomotor task on a treadmill, changes in the hemodynamic response in the front-parietal area of healthy human subjects are simultaneously recorded using an fNIRS imaging system and a laser Doppler tissue blood ...

Pharmacological removal of serum amyloid P component from intracerebral plaques and cerebrovascular Aβ amyloid deposits in vivo [PDF]

Open Biology, 2016
Human amyloid deposits always contain the normal plasma protein serum amyloid P component (SAP), owing to its avid but reversible binding to all amyloid fibrils, including the amyloid β (Aβ) fibrils in the cerebral parenchyma plaques and cerebrovascular ...

Removal of blood components from cervical smears: Implications for cancer diagnosis using FTIR spectroscopy [PDF]

Biopolymers, 2002
AbstractRed and white cell lysis buffers were investigated to determine their ability to remove blood components from cervical smears prior to IR microspectroscopy. A white cell lysis buffer was effective in increasing the spectral reproducibility and sample homogeneity and in reducing the presence of inflammatory exudate, particularly leukocytes, from

Assessment of removal of human cytomegalovirus from blood components by leukocyte depletion filters using real-time quantitative PCR [PDF]

Blood, 2003
Abstract To assess removal of cytomegalovirus (CMV) by leukocyte depletion (LD) filters, we developed a spiking model of latent virus using peripheral blood mononuclear cells (PBMCs) infected by coculture with CMV-infected human fibroblasts.

Preclinical transmission of prions by blood transfusion is influenced by donor genotype and route of infection.

PLoS Pathogens, 2021
Variant Creutzfeldt-Jakob disease (vCJD) is a human prion disease resulting from zoonotic transmission of bovine spongiform encephalopathy (BSE). Documented cases of vCJD transmission by blood transfusion necessitate on-going risk reduction measures to ...

Low-flow assessment of current ECMO/ECCO2R rotary blood pumps and the potential effect on hemocompatibility

Critical Care, 2019
Background Extracorporeal carbon dioxide removal (ECCO2R) uses an extracorporeal circuit to directly remove carbon dioxide from the blood either in lieu of mechanical ventilation or in combination with it.

Peculiarities of the formation and subsequent removal of the circulating immune complexes from the bloodstream during the process of digestion [version 1; referees: 2 approved, 1 approved with reservations]

F1000Research, 2018
Background: Large protein aggregates, known as circulating immune complexes (CICs), are formed in biological fluids as a result of the development of the body's immune response to various provoking factors.

A Resilient, Non-neuronal Source of the Spatiotemporal Lag Structure Detected by BOLD Signal-Based Blood Flow Tracking

Frontiers in Neuroscience, 2017
Recent evidence has suggested that blood oxygenation level-dependent (BOLD) signals convey information about brain circulation via low frequency oscillation of systemic origin (sLFO) that travels through the vascular structure (“lag mapping”).

Automatic Removal of Cardiac Interference (ARCI): A New Approach for EEG Data

Frontiers in Neuroscience, 2019
EEG recordings are generally affected by interference from physiological and non-physiological sources which may obscure underlying brain activity and hinder effective EEG analysis.
