Contrast‐enhanced micro‐computed tomography of compartment and time‐dependent changes in femoral cartilage and subchondral plate in a murine model of osteoarthritis

The Anatomical Record, Volume 306, Issue 1, Page 92-109, January 2023., 2023
Abstract A lack of understanding of the mechanisms underlying osteoarthritis (OA) progression limits the development of effective long‐term treatments. Quantitatively tracking spatiotemporal patterns of cartilage and bone degeneration is critical for assessment of more appropriately targeted OA therapies.

Modelling confounding effects from extracerebral contamination and systemic factors on functional near-infrared spectroscopy [PDF]

, 2016
Haemodynamics-based neuroimaging is widely used to study brain function. Regional blood flow changes characteristic of neurovascular coupling provide an important marker of neuronal activation.

Regional blood flow distribution in dog during induced hypotension and low cardiac output. Spontaneous breathing versus artificial ventilation.

Journal of Clinical Investigation, 1983
Respiratory muscle blood flow and organ blood flow was studied in two groups of dogs with radioactively labeled microspheres to assess the influence of the working respiratory muscles on the regional distribution of blood flow when arterial pressure and ...

The Awakening Brain is Characterized by a Widespread and Spatiotemporally Heterogeneous Increase in High Frequencies

Advanced Science, EarlyView.
This work explores the process of morning awakening of the human brain using polysomnography paired with simultaneous stereo‐electroencephalography, a method that provides high spatial and temporal resolution for examining brain activity. Awakening is characterized by an increase in high‐frequency spectral power and connectivity.

Parametric Features of Regional Cerebral Blood Flow in Venous Ischemic Stroke

Acta Biomedica Scientifica, 2019
The lecture is devoted to the peculiarities of changes in tissue and cell perfusion of the brain with a rare pathology – venous ischemic stroke. Venous stroke, being a “relatively unknown cerebrovascular disease”, occurs up to 5 % of all cases of stroke.

Delivery of Human iPSC‐Derived RPE Cells in Healthy Minipig Retina Results in Interaction Between Photoreceptors and Transplanted Cells

Advanced Science, EarlyView.
Human induced pluripotent stem cell‐derived retinal pigment epithelial (hiPSC‐RPE) cells, cultured on a clinically relevant PDLLA scaffold, are transplanted into immunosuppressed minipigs. The study demonstrates the viability, integration, and preservation of RPE‐specific features without gliosis or neuroinflammation, supporting their potential as a ...
