Real-time monitoring of mitochondrial oxygenation during machine perfusion using resonance Raman spectroscopy predicts organ function

Scientific Reports
Organ transplantation is a life-saving procedure affecting over 100,000 people on the transplant waitlist. Ischemia reperfusion injury (IRI) is a major challenge in the field as it can cause post-transplantation complications and limit the use of organs ...

Hepatocyte PIEZO1 Negatively Regulates Lipogenesis and Ameliorates MASLD by Sensing Membrane Tension and Activating AMPK

Advanced Science, EarlyView.
Hepatocytes are subjected to increased membrane tension along with lipid accumulation. Loss of PIEZO1 exacerbates high‐fat diet‐induced MASLD in mice. Activation of PIEZO1 alleviates high‐fat diet‐induced MASLD in mice. PIEZO1 negatively regulates de novo lipogenesis through activation of CaMKK2‐AMPK pathway. ABSTRACT Liver is a central organ for lipid

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

Advanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Therapeutic agents for machine perfusion of donor organs

Трансплантология (Москва)
Background. The urgency of the unmet need for transplant care dictates the necessity to use organs from suboptimal donors. Machine perfusion, which is actively developing at the present time, is designated to solve this problem.

Discovery of an Adaptive Neuroimmune Response Driving Itch and Fast Tick Removal with Implications for Preventing Pathogen Transmission

Advanced Science, EarlyView.
Itch‐induced tick removal (IITR): An acquired neuroimmune mechanism, itch‐induced tick removal, develops after repeated tick exposure, mobilizing T cells and macrophages at the tick bite site to trigger a rapid scratching response that facilitates timely tick removal within a critical window that precedes the transmission of many tick‐borne pathogens ...

Localized NF‐κB Inhibition Reduces Lipid Nanoparticle‐Associated Inflammation

Advanced Science, EarlyView.
Lipid nanoparticles (LNPs) activate NF‐κB and provoke inflammation that limits therapeutic delivery. By encapsulating selective NF‐κB inhibitors within LNPs, localized suppression of inflammatory signaling is achieved without compromising mRNA expression.

Postsynaptic Complexin Mediates Constitutive Exocytosis of Nicotinic Acetylcholine Receptor

Advanced Science, EarlyView.
Beyond its established presynaptic role, complexin is identified as a postsynaptic regulator of neurotransmitter receptor trafficking. By promoting constitutive and activity‐dependent exocytosis of nicotinic acetylcholine receptors, complexin controls spontaneous synaptic signaling at the C.

Persistently Increased Expression of PKMzeta and Unbiased Gene Expression Profiles Identify Hippocampal Molecular Traces of a Long‐Term Active Place Avoidance Memory and “Shadow” Proteins

Advanced Science, EarlyView.
Protein complexes like KIBRA‐PKMζ are crucial for maintaining memories, forming month‐long protein traces in memory‐tagged neurons, but conventional RNA‐seq analysis fails to detect their transcript changes, leaving memory molecules undetected in the shadows of abundantly‐expressed genes.

A Comparative Study for 2D and 3D Computer-aided Diagnosis Methods for Solitary Pulmonary Nodules [PDF]

, 2008
Many computer-aided diagnosis (CAD) methods, including 2D and 3D approaches, have been proposed for solitary pulmonary nodules (SPNs). However, the detection and diagnosis of SPNs remain challenging in many clinical circumstances.
