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

open access: yesAdvanced 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 ...

Korelacija između slikovnog prikaza magnetskom rezonancijom i histopatologije u diferencijaciji bolesti gušterače [PDF]

open access: yes, 2011
In the last four decades, the incidence of pancreatic cancer has tripled in Western countries. More than 90% of all pancreatic cancers are detected in the advanced stage of the disease when surgical treatment is no longer possible and survival after ...

F‐Box and Leucine‐Rich Repeat Protein 4 (FBXL4) Maintains Sarcomere Integrity and Cardiac Function by Enhancing K48‐Linked Ubiquitinated Degradation of Profilin‐1 (PFN1)

open access: yesAdvanced Science, EarlyView.
Schematic diagram depicting the proposed signaling mechanisms underlying the effects of FBXL4 in the setting of cardiac hypertrophy. Under hypertrophic stimulation, cardiomyocytes‐specific overexpression FBXL4 maintains sarcomere integrity and cardiac function by enhancing K48‐linked ubiquitinated degradation of PFN1 at the K70 site.

Targeted Extracellular Vesicles Deliver Asiaticoside to Inhibit AURKB/DRP1‐Mediated Mitochondrial Fission and Attenuate Hypertrophic Scar Formation

open access: yesAdvanced Science, EarlyView.
Hypertrophic scar formation is driven by excessive mitochondrial fission in wound macrophages, which we discover is governed by a novel AURKB‐DRP1(Ser616) axis. The study develops a targeted therapy using cRGD‐decorated extracellular vesicles to deliver the natural compound Asiaticoside specifically to macrophages.

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

open access: yesAdvanced Science, EarlyView.
Doehl et al. discovered an adaptive neuroimmune mechanism that induces itch in tick‐exposed guinea pigs, enabling rapid tick removal. This itch‐induced tick removal (IITR) is mediated by an adaptive cellular immune response and is independent of IgG, IgE, or TRPV1.

Gram‐Scale Synthesis of Hafnium‐Rich Carbon Dots for Preclinical Computed Tomography Imaging Across Various Systems

open access: yesAdvanced Science, EarlyView.
Hafnium (Hf)‐rich carbon dots (Hf‐rCDs) with high metal content (40.7%) and robust batch production capacity (>2 g per batch) are synthesized via a facile air‐assisted pyrolysis method. In vivo CT imaging demonstrates outstanding performance of Hf‐rCDs across multiple physiological systems and enables high‐resolution visualization of swine cervical ...

Oral Celastrol Nanomedicine Targeting Intestinal Antigen‐Presenting Cells to Effectively Mitigate Autoimmune Uveitis via Gut‐Retina Axis

open access: yesAdvanced Science, EarlyView.
Oral nanoCEL exhibits effective intestinal targeting of antigen‐presenting cells and restores the Th17/Treg balance in lymph nodes and spleen, ultimately protecting the blood‐retinal barrier by inhibiting peripheral immune cell infiltration and suppressing retinal glial cell activation.

TRAP5 Inhibition Targeting Scar‐Associated Macrophages Ameliorates Acute Kidney Injury to Chronic Kidney Disease Transition

open access: yesAdvanced Science, EarlyView.
This study delineates macrophage heterogeneity along the acute kidney injury to chronic kidney disease transition. Single‐cell RNA sequencing reveals a TRAP5+ scar‐associated macrophage subset driven by Spp1–Cd44 signaling and mitochondrial metabolic reprogramming.

Multi‐Organelle Stress‐Induced Paraptosis by a ROS‐Amplifying Nanocatalyst for Enhanced Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
The engineered TF‐Fe@LC nanoplatform programs paraptotic death via multipath ROS amplification that disrupts redox homeostasis, provoking mitochondrial dysfunction, autophagic blockade, and ER stress. This caspase‐independent process elicits robust immunogenic cell death, combining with αPD‐L1 to activate systemic CD8+ T‐cell immunity and suppress ...

Critical upward shift of intracranial pressure levels in extremely obese patients; normalization due to bariatric surgery

open access: yesThe Ultrasound Journal
Background Increase in body mass index (BMI) is a risk factor for idiopathic intracranial hypertension (IIH). The matter of body weight and intracranial pressure (ICP) in clinically asymptomatic obese patients is unknown.
