Scintigraphic Assessment of Lung Perfusion and Ventilation in Patients After Pneumonectomy

Background/Objectives: The physiological ventilation–perfusion ratio (V/Q) in the upper pulmonary field is >3 and in the lower pulmonary field it is <1 due to the effect of gravity when the body is in an upright position.

Cannabigerol reverses mechanical allodynia through α2A‐adrenergic modulation of thalamocortical signaling in chemotherapy‐induced neuropathy

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Chemotherapy‐induced peripheral neuropathy (CIPN) is a prevalent and treatment‐resistant side effect of platinum‐based chemotherapy, characterised by mechanical allodynia. Cannabigerol (CBG), a non‐psychoactive cannabinoid, has shown antinociceptive potential, but its site and mechanism of action remain unclear.

Rifaximin ameliorates memory impairment and Alzheimer's pathological changes in APP/PS1 mice associated with changes in the gut microbiome–bile acids–serum metabolites networks

British Journal of Pharmacology, EarlyView.
Background and Purpose Modifying the brain–gut–microbiota axis has emerged as a promising therapeutic strategy against Alzheimer's disease (AD). Whether rifaximin, a non‐absorbed and non‐systemic antibiotic, can be applied to the treatment of AD remains unexplored.

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

The FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

Ventilation-perfusion imaging in evaluating regional lung function in nonpenetrating injury to the chest

, 1989
The extent of chest wall and lung injury after nonpenetrating injury to the chest (NIC) determine how aggressive and invasive management modalities should be. We investigated the value of ventilation (133Xe) and perfusion (99mTc) studies as indicators of

A validated deep learning workflow for 3D quantification of amyloid plaques in cleared mouse brain

Journal of Microscopy, EarlyView.
Abstract Accurate quantification of amyloid plaque pathology is essential for understanding Alzheimer's disease (AD) progression and evaluating therapeutic interventions. Yet, conventional histology relies on sampling thin tissue sections and therefore incompletely captures three‐dimensional (3D) plaque distributions, introducing bias and limiting ...
