Cryoprobe biopsy increases the diagnostic yield in endobronchial tumor lesions [PDF]

, 2010
ObjectiveForceps biopsy is the standard method to obtain specimens in endoscopically visible lesions. It is common to combine forceps biopsy with cytology methods to increase the diagnostic yield.

Bronchoscopic retrieval of an aspirated tooth following high‐speed motor vehicle accident

Respirology Case Reports
Key message A 28‐year‐old man aspirated a tooth into his right lower lobe bronchus following a high‐speed motor vehicle accident. Initial retrieval attempts failed with a flexible bronchoscope, but a cryoprobe successfully dislodged and retrieved the ...

Evaluating the Influence of Injury‐Induced Microstructural Variations on the Efficacy of a Diffusion MRI‐Derived Axon Diameter Surrogate

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1355-1364, September 2026.
ABSTRACT Purpose To investigate the utility of a recently demonstrated diffusion MRI derived axon diameter surrogate measure (∆D⟂) under pathologic conditions induced by a spinal cord injury model. Methods Contusion injuries were performed on the thoracic–lumbar spinal cord of adult male rats.

Use of the Ion Robot in the Diagnosis of Pulmonary Nodules: Fine Needle Aspiration Versus Cryobiopsy

Diagnostic Cytopathology, Volume 54, Issue 8, Page 562-567, August 2026.
ABSTRACT Background Robotic‐assisted bronchoscopy platforms provide an innovative approach to the sampling of pulmonary nodules. As compared to other technologies, fiber‐optic shape‐sensing instrumentation allows for a more precise, accurate location and sampling of the target lesion with fewer complications.

A Stopped‐Flow Instrument for Millisecond Timescale Reaction Monitoring on a Standard NMR Spectrometer

Magnetic Resonance in Chemistry, Volume 64, Issue 8, Page 711-728, August 2026.
A new stopped‐flow instrument allows kinetic measurements of reactions 10 milliseconds after initiating them by mixing in a flow cell inserted into a standard NMR probe and spectrometer. High‐speed video, pressure and NMR line‐shape data are used to characterise mixing and stopping, and a protodeboronation reaction with a 5‐millisecond half‐life used ...

Quantitative Imaging of Pyruvate Metabolism in a Patient With Anaplastic Thyroid Cancer

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 826-838, August 2026.
ABSTRACT Purpose Magnetic resonance imaging using hyperpolarized (HP) [1‐13C]‐pyruvate enables assessment of pyruvate metabolism in vivo and offers new insight into metabolic changes in response to cancer therapy. Widely used semi‐quantitative metrics of pyruvate metabolism can be affected by physiological factors that are extrinsic to intracellular ...

Image of a thawed frozen specimen obtained using a cryoprobe floated with oil droplets in normal saline: An endobronchial lipomatous hamartoma image

Respirology Case Reports
Key message Hereby, we present a rare case of a resected endobronchial tumour that floated or showed oil droplets in saline. In this study, we report an interesting image related to endobronchial lipomatous hamartoma cryotherapy.

Identification and Optimization of a Truncated Hs‐1‐Derived Antimicrobial Peptide for Enhanced Broad‐Spectrum Antiviral Activity

ChemMedChem, Volume 21, Issue 13, 14 July 2026.
Can a shorter peptide be a better antiviral? Structure‐guided optimization of the amphibian peptide Hs‐1 reveals a minimal α‐helical core that, after terminal modification, displays enhanced stability and submicromolar broad‐spectrum activity against enveloped viruses while maintaining a favorable safety profile. Antimicrobial peptides (AMPs) represent
