Effects of 1267 nm Illumination on Microcirculation Regulatory Mechanisms

Journal of Biophotonics, EarlyView.
The question of activation of blood flow regulatory mechanisms during laser illumination remains open to date. This study showed the effect of laser exposure on the microcirculatory bed, which appears in the form of endothelium‐dependent vascular activity.

A Novel Approach to Sequential Organ Failure Assessment (SOFA) Using Near‐Infrared Spectroscopy in Extracorporeal Membrane Oxygenation (ECMO) Patients

Journal of Biophotonics, EarlyView.
This study utilized near‐infrared spectroscopy to monitor real‐time blood oxygen changes in the lower limb microcirculation of ECMO patients and performed disease severity classification based on this information. The classification models demonstrated strong predictive performance in both VV‐ECMO and VA‐ECMO patients.

Associations of Central Arterial Stiffness With Brain White Matter Integrity and Gray Matter Volume in MRI Across the Adult Lifespan

Journal of Magnetic Resonance Imaging, EarlyView.
Background Central arterial stiffening is associated with brain white matter (WM) damage and gray matter (GM) volume loss in older adults, but little is known about this association from an adult lifespan perspective. Purpose To investigate the associations of central arterial stiffness with WM microstructural organization, WM lesion load, cortical ...

Dissociation of red blood cell aggregates in extensional flow [PDF]

Phys. Rev. Fluids 9, L071101 (2024)
Blood rheology and microcirculation are strongly influenced by red blood cell aggregation. We investigate the dissociation rates of red cell aggregates in extensional flow using hyperbolic microfluidic constrictions and image analysis by a convolutional neural network (CNN).

Quantitative Dynamic Contrast‐Enhanced Ultrasound Confirms Renal Obstruction

Journal of Ultrasound in Medicine, EarlyView.
Objectives To evaluate dynamic contrast‐enhanced ultrasound (DCEUS) potential for diagnosing ureteropelvic junction obstruction (UPJO). We hypothesize that DCEUS can identify differences in renal parenchymal microcirculation between normal and obstructed kidneys.

Mechanistic Insights Into hsa_circ_0005654‐Induced Ferroptosis in Diabetic Foot Ulcers Through IGF2BP2 Interaction

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study investigated the molecular mechanism by which hsa_circ_0005654 aggravates diabetic foot ulcers (DFUs) by promoting ferroptosis. A DFU rat model was established, and lentiviral vectors interfering with circ_0005654 and IGF2BP2 expression were injected into DFU rats by tail vein.

Percutaneous Bone Implant Surgery: A MIPS Modified Technique

The Laryngoscope, EarlyView.
Since their introduction, passive percutaneous hearing aids have undergone substantial evolution, including changes in implant production, improvements in the sound processor, and simplification of surgical implantation techniques. The latest innovation comes from the minimally invasive technique proposed for the PONTO system (MIPS), which does not ...

Yerba Mate (Ilex paraguariensis St. Hill.) Tea May Have Cardiometabolic Beneficial Effects in Healthy and At‐Risk Subjects: A Randomized, Controlled, Blind, Crossover Trial in Nonhabitual Consumers

Molecular Nutrition &Food Research, EarlyView.
Yerba mate intake shows cardiometabolic beneficial effects decreasing blood pressure, blood lipids, inflammatory biomarkers and body fat in healthy and hypercholesterolemic non‐habitual consumers. ABSTRACT Yerba mate has been reported to have antihypertensive, hypocholesterolemic, antidiabetic, or antiobesity properties.

Determining the utility of ultrafast nonlinear contrast enhanced and super resolution ultrasound for imaging microcirculation in the human small intestine [PDF]

arXiv
The regulation of intestinal blood flow is critical to gastrointestinal function. Imaging the intestinal mucosal micro-circulation in vivo has the potential to provide new insight into the gut physiology and pathophysiology. We aimed to determine whether ultrafast contrast enhanced ultrasound (CEUS) and super-resolution ultrasound localisation ...

Combinatorial therapy with two pro-coagulants and one osmotic agent reduces the extent of the lesion in the acute phase of spinal cord injury in the rat

Intensive Care Medicine Experimental, 2017
Background Spinal cord injury (SCI) is a complex disease that leads to a motor, sensitive, and vegetative impairment. So far, single therapies are ineffective for treating SCI in humans and a multifactorial therapeutic approach may be required.
