Stereotactic Gamma Knife Radiosurgery for Merkel cell carcinoma brain metastases: case report and systematic review of literature

open access: yesBrain and Spine
Introduction: Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine skin malignancy with an increasing incidence. Although it frequently presents with loco-regional metastases, brain metastases (BMs) are exceptionally rare, lacking ...

A Multimodal Haptic Feedback Interface with Thin‐Film Compliant Mechanism

open access: yesAdvanced Science, EarlyView.
Multimodal haptic devices can trigger different mechanoreceptors, enabling richer haptic information. This study presents an electromagnetic multimodal haptic device capable of delivering indentation, stretch, and vibration stimuli. The device is enabled by a novel polymer thin‐film compliant mechanism that provides high translational compliance along ...

Individualized Prediction of Meningioma Response to Gamma Knife Radiosurgery Using Nested Consensus Machine Learning with 3D Fractal, Lacunarity and Radiomic Features from MRI

open access: yesFractal and Fractional
Background: This study aimed to develop a fully nested, information leakage-free machine-learning workflow to predict the volumetric response of meningioma to Gamma Knife radiosurgery (GKRS) from pre-treatment MRI and to compare the predictive value of ...

Eco‐Friendly Solvent System for Inkjet Deposition of Wide Bandgap Perovskite Solar Cells Enabling Tandem Integration

open access: yesAdvanced Science, EarlyView.
The fabrication of wide‐bandgap perovskite thin films via green solvents integrated with inkjet printing is developed. Controlled crystallization of the perovskite layer is achieved by optimizing ink formulation and additive engineering, enabling power conversion efficiencies above 17% for single junctions and 28% for perovskite/silicon tandem solar ...

Targeted Degradation of Picornaviral 3C Protease via PROTACs Confers High Barrier to Viral Resistance and Broad‐Spectrum Antiviral Activity

open access: yesAdvanced Science, EarlyView.
This study reports D34 as the first PROTAC degrader that targets the 3C protease of picornaviruses. D34 effectively degrades EV71 3C protease via the ubiquitin‐proteasome pathway. More importantly, D34 exhibits a high resistance barrier and shows broad‐spectrum antiviral activity against multiple picornaviruses, highlighting its potential as a novel ...

Long-Term Survival of a Patient with Brainstem and Recurrent Brain Metastasis from Stage IV Nonsmall Cell Lung Cancer Treated with Multiple Gamma Knife Radiosurgeries and Craniotomies: A Case Report and Review of the Literature

open access: yesCase Reports in Oncological Medicine, 2012
The prognosis of patients diagnosed with stage IV nonsmall cell lung cancer that have brain and brainstem metastasis is very poor, with less than a third surviving a year past their initial date of diagnosis. We present the rare case of a 57-year-old man

Early and High‐Dose Glucocorticoid Use and Survival in Advanced NSCLC Receiving Immune Checkpoint Inhibitors: A Multicenter Target Trial Emulation

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Despite the immunomodulatory mechanism of immune checkpoint inhibitors (ICIs), systemic glucocorticoids are commonly used in advanced non–small cell lung cancer (NSCLC). Evidence regarding their effects on ICI outcomes is inconsistent, in part due to confounding by indication and immortal time bias.

Dynamic cracking properties and generating conditions of coal under rapid gas release

open access: yesDeep Underground Science and Engineering, EarlyView.
Gas release tests revealed that crack initiation and propagation are jointly controlled by initial crack length, residual strength, and gas release velocity. A new outburst risk coefficient was thus developed from a fracture mechanics perspective, offering a novel predictive approach.
