Magnetic Resonance Imaging Evaluation of Functional Differences Between In Vivo Human Kidneys and Discarded Human Kidneys During Ex Vivo Normothermic Machine Perfusion

Artificial Organs, EarlyView.
Comparative MRI of in vivo kidneys and ex vivo donor kidneys during NMP revealed marked physiological differences and limited correspondence with conventional perfusion or injury metrics. These distinct ex vivo MRI signatures emphasize the need to consider parameters beyond conventional in vivo functional markers when assessing organ viability during ...

Retinotopic Mapping using Arterial Spin Labeling fMRI

, 2009
Arterial Spin Labeling (ASL) is a magnetic resonance imaging (MRI) method to map the cerebral blood flow (CBF). ASL present a non-invasive alternative to the contrast agent and ASL techniques are capable of providing quantitative information about local ...

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Improving Arterial Spin Labeling using Deep Learning

, 2018
We proposed a new convolutional neural network (CNN) framework to quantify cerebral blood flow (CBF) in Hadamard-encoded pseudo-continuous arterial spin labeling (HE-pCASL).

Dual pharmacological targeting of coactivator‐associated arginine methyltransferase 1 (CARM1) and salt inducible kinase (SIK) drives ketogenesis in both hepatocytes and mice

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ketone bodies are liver‐derived circulating energy metabolites that positively impact most hallmarks of ageing. Ketone bodies increase during calorie restriction and fasting, two of the more widely perceived methods to increase health span.

Irradiated Liver Cancer Cell Vaccine Transfected With GM‐CSF Induces Specific and Long‐Lasting Anti‐tumour Immunity Through the Synergistic Effect of Oxidised mtDNA and GM‐CSF

Cell Proliferation, EarlyView.
Song et al. developed an mGM‐CSF‐loaded, liver cancer cell‐based vaccine that potently activated dendritic cells and elicited tumour‐specific T cell responses. Mechanistically, radiation‐induced oxidative damage to mitochondrial DNA in cancer cells triggers the cGAS‐STING pathway in DCs, which synergizes with mGM‐CSF‐driven JAK2‐STAT3 signalling to ...

A Specific tRNA Half, 3'tiRNA‐GlyGCC, Regulates Hypoxic Pulmonary Artery Smooth Muscle Cell Proliferation via Myrf‐Mediated Endoplasmic Reticulum Stress

Cell Proliferation, EarlyView.
A schematic diagram illustrating how 3′tiRNA‐GlyGCC promotes the endoplasmic reticulum stress (ERS) and proliferation in hypoxic pulmonary artery smooth muscle cells (PASMCs) by inhibiting the expression of myelin regulatory factor (Myrf), ultimately leading to pulmonary hypertension (PH).

Multi‐Parametric Magnetic Resonance Imaging to Assess Empagliflozin Effect on the Kidneys in People With Type 2 Diabetes Mellitus: A Pilot Clinical Trial

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Empagliflozin is renoprotective in Type 2 diabetes mellitus (T2DM). Our primary aim was to assess empagliflozin's effect on glomerular filtration rate and renal vascular resistance using multiparametric MRI (MpMRI). Our secondary aim was to assess the impact of empagliflozin on additional MpMRI‐derived metrics including markers of tissue ...

Tenapanor Beyond Phosphate: Gut Sodium Transport, Stool Transit Time, and Volume Balance in Dialysis Patients

Hemodialysis International, EarlyView.
ABSTRACT Introduction Tenapanor, a minimally absorbed intestinal NHE3 inhibitor approved for hyperphosphatemia in dialysis, lowers phosphate and reduces intestinal sodium absorption. Its sodium–water signal may have implications beyond phosphate but remains poorly separated from diarrhea‐mediated losses and dialysis prescription artifacts. Methods This

Far‐infrared irradiation attenuates platelet‐derived growth factor‐stimulated vascular smooth muscle cell migration through protein phosphatase 2A‐mediated Akt inhibition

Photochemistry and Photobiology, EarlyView.
FIR irradiation enhances the physical association between Akt and PP2Ac in VSMCs, independent of the hyperthermal effect of FIR rays. The increased binding between Akt and PP2Ac induced by FIR irradiation facilitates the dephosphorylation of Akt at Ser473.
