Investigation of Lower-limb Tissue Perfusion during Loading [PDF]

open access: yes, 2002
An extant tissue indentor used for amputee residual limb tissue indentation studies was modified to include laser Doppler flowmetry (LDF) to enable measurement of tissue perfusion during indentation.

TECHNIQUES OF EVALUATION OF HEMOGLOBIN OXYGEN SATURATION IN CLINICAL OPHTHALMOLOGY

open access: yesBiomedical Photonics, 2017
Oxygen content in body fluids and tissues is an important indicator of life support functions. A number of ocular pathologies, e.g. glaucoma, are of presumable vascular origin which means altered blood supply and oxygen circulation.

The Potential of Ensemble‐Based Automated Sleep Staging on Single‐Channel EEG Signal From a Wearable Device

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Machine‐learning‐based sleep staging models have achieved expert‐level performance on standard polysomnographic (PSG) data. However, their application to EEG recorded by wearable devices remains limited by non‐conventional referencing montage and the lack of benchmarking against PSG.

Delta‐9‐Tetrahydrocannabinol (THC) Before Bedtime: Feasibility and Mechanistic Pilot Study on Sleep and Cardiac Autonomic Activity

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Disordered sleep is a common reason individuals report using cannabis, yet the physiological effects of Δ9‐tetrahydrocannabinol (Δ9‐THC) on sleep and autonomic regulation remain incompletely understood. Early studies reported acute sleep‐promoting effects of Δ9‐THC, but chronic use has been associated with disrupted sleep and possible ...

Nocturnal Sleep Breathing Patterns in Healthy Adolescents Residing at Very High Altitudes in Bolivia

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Data on sleep and respiratory patterns among adolescents residing at very high altitude (> 3500 m) remain scarce, and altitude‐related physiological differences may influence these parameters. Studying adolescents at different very high altitudes is crucial, as subtle environmental variations could affect sleep‐related oxygenation and ...

Consensus on the Management of Anesthetic Agents During Digestive Motility Measurements and Proposal of a Standardized Protocol for Anesthesia (French Neuro Gastroenterology Group GFNG and Committee of Anesthetic French Experts)

open access: yesNeurogastroenterology &Motility, EarlyView.
Anesthesia can alter measurements during digestive endoscopies, yet no standardized protocol currently exists. Two expert groups—the French Neuro‐Gastroenterology Group (GFNG) and anesthesiologists—used the Delphi method to reach a consensus on which drugs have an influence (91 amendments), ultimately resulting in a proposed anesthesia protocol (28 ...

Early prediction of transfusion requirements in trauma patients using explainable machine learning

open access: yesTransfusion, EarlyView.
Abstract Introduction Hemorrhagic shock is the most common preventable cause of death in trauma patients. Early transfusion significantly improves survivability in patients suffering from hemorrhagic shock. We hypothesized that machine learning models could reduce time to initial transfusion by more rapidly identifying patients likely to require blood ...

Lateral Tarsorrhaphy and Fixation on the Orbital Ligament to Correct Macroblepharon in Dogs: 77 Palpebral Fissures

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 448-456, March 2025.
ABSTRACT Purpose To describe a surgical method for correcting lower lid entropion, lateral canthal entropion, and macroblepharon. Methods Lid margins were incised at a 45° angle, and lateral lid margins and a rhomboid shaped piece of skin were resected based on the degree of macroblepharon.
