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 ...

Bilateral lung disease, extensive and diffuse. Diagnosis of pulmonary alveolar proteinosis by bronchoscopic cryobiopsy

Respiratory Medicine Case Reports, 2017
Pulmonary alveolar proteinosis (PAP) is a rare disease characterized by the intra-alveolar accumulation of a proteinaceous phospholipid-laden material called surfactant. Clinically, this disease should be suspected with respiratory failure in association

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 ...

METHOD OF LOCAL ADRENAL ORGAN-PRESERVING CRYOLYSIS. EXPERIMENTAL STUDY

Бюллетень сибирской медицины, 2013
A method of local adrenal organ-preserving cryolysis using a porous nickelide titanium cryoprobe created for this purpose was developed in experiments in 14 dogs. The efficacy of the method was demonstrated by the morphological evidence and hormone tests.

Damping amyloid‐associated conformational fluctuations in a protein by an engineered diselenide bridge

Protein Science, Volume 35, Issue 8, August 2026.
Abstract Polypeptide cross‐β assembly, characteristic of diverse proteotoxic diseases, defines a general thermodynamic ground state and limits the shelf lives of peptide‐ and protein therapeutics. A model is provided by insulin. Although the hormone contains a predominance of α‐helix, its fibrils exhibit cross‐β reorganization.

Bronchoscopic Removal of Aspergilloma in a 26‐Year‐Old Man

Respirology Case Reports, Volume 14, Issue 8, August 2026.
A 26‐year‐old man with posttuberculous aspergilloma and a prior contralateral pneumonectomy remained refractory to voriconazole but was ineligible for surgery. The friable fungal ball was fragmented and completely extracted bronchoscopically over two sessions using progressively larger bronchoscopes, forceps, a Fogarty catheter and suction.

Successful Diagnostic Confirmation of Malignant Pleural Mesothelioma With Extensive Pleural Adhesions Using Pleural Cryobiopsy Under Local Anaesthesia

Respirology Case Reports, Volume 14, Issue 8, August 2026.
Pleural cryobiopsy under local anaesthesia enabled definitive diagnosis of malignant pleural mesothelioma despite extensive pleural adhesions. Careful preoperative assessment and precise lesion localisation allowed safe and minimally invasive tissue acquisition in a high‐risk patient.
