We report a successful case of thoracoscopic therapy using a new biological adhesive agent, Gelatin-Resorcinol Formaldehyde glue (GRFG glue) for refractory pulmonary fistula. A 69-year-old male underwent right upper lobectomy for lung aspergilloma. Air leakage began 11 days after lobectomy. Closing alveolar fistula was performed 28 days after first operation. Relapsing air leakage began 2 days after second operation. The insertion of fibrin glue through thoracoscope at two times was not effective for refractory pulmonary fistula. But the insertion of GRFG glue was effective to close the fistula completely.

Various attempts have been made to elucidate the mechanisms of human lung development, its physiological functions, and diseases, in the hope of new drug discovery. Recent technological advancements in experimental animals, cell culture, gene editing, and analytical methods have provided new insights and therapeutic strategies. However, the results obtained from animal experiments are often inconsistent with those obtained from human data because of reproducibility issues caused by structural and physiological differences between mice and humans.

Exploiting YES1-driven EGFR expression improves the efficacy of EGFR inhibitors.

Epidermal growth factor receptor (EGFR) is a highly expressed driver of many cancers, yet the utility of EGFR inhibitors is limited to cancers that harbor sensitizing mutations in the EGFR gene due to dose limiting toxicities. Rather than conventionally blocking the kinase activity of EGFR, we sought to reduce its transcription as an alternative approach to broaden the therapeutic window for EGFR inhibitors targeting wildtype or mutant EGFR. We found that YES1 is highly expressed in triple negative breast cancer (TNBC) and drives cell growth by elevating EGFR levels.

Cancer cells in the tumour microenvironment use various mechanisms to evade the immune system, particularly T cell attack. For example, metabolic reprogramming in the tumour microenvironment and mitochondrial dysfunction in tumour-infiltrating lymphocytes (TILs) impair antitumour immune responses. However, detailed mechanisms of such processes remain unclear.

Chronic cough is defined as a persistent cough, lasting beyond 8 weeks, poses a global health challenge, impacting a substantial portion of the world's population. In the United States, it stands as a prominent cause for numerous visits to primary care and pulmonology clinics, imposing a significant healthcare burden and utilizing valuable resources. While chronic cough can be indicative of serious underlying lung conditions, once serious pulmonary diseases are excluded, the leading culprits are often identified as gastroesophageal reflux, upper airway cough syndrome, and eosinophilic airway inflammation.
