Enhancer Reprogramming Reveals the Tumorigenic Role of PTPRZ1 in Lung Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
Lung squamous cell cancer (LUSC) is deadly due to lack of good treatments. Here, multiomics techniques are applied to LUSC tumors and find thousands of cancer‐specific enhancers controlling key genes. Interestingly, the gene PTPRZ1 is identified as a critical oncogene driven by the LUSC‐acquired enhancers. PTPRZ1 is activated by MDK, fueling cancer via

Punicalagin Enhances Autophagy Through Sirtuin 1/FoxO3a Axis to Inhibit Intracellular Mycobacterium Abscessus Infection

open access: yesAdvanced Science, EarlyView.
Punicalagin, a pomegranate molecule, helps the body fight Mycobacterium abscessus. It preferentially boosts interstitial macrophages in the lung, stabilizing mitochondria and switching on the autophagy via SIRT1/FoxO3a, which lowers bacterial load without directly killing bacteria.

Testing of novel spectral device sensor in swine model of airway obstruction

open access: yesPhysiological Reports, 2019
Loss of a patent airway is a significant cause of prehospital death. Endotracheal intubation is the gold standard of care but has a high rate of failure and complications, making development of new devices vital. We previously showed that tracheal tissue

Cyclic Strain and Macrophage‐Mediated Transport Govern Micron‐Sized PM2.5 Translocation across the Air–Blood Barrier

open access: yesAdvanced Science, EarlyView.
Using a dynamic, tri‐culture air‐blood barrier model, this study reveals that macrophage‐mediated transport governs micron‐sized particle translocation under cyclic strain. The process is highly size‐dependent that 2 µm particles are transported by macrophages, 0.2 µm particles diffuse passively, and 5 µm particles are effectively blocked.

The Comparison of Nasopharyngeal Cephalometric Measurements between Two Groups with Anterior and Posterior Obstructions of Nasal Airway

open access: yesMajallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2004
Introduction: Two main causes of nasal airway obstruction and mouth breathing Consist: 1- anterior nasal obstruction is caused by obstruction in nasal cavity, 2- posterior (nasopharyngeal) obstruction is caused by adenoid enlargement and decreased ...

The diagnosis and treatment of elderly patients with acute exacerbation of chronic obstructive pulmonary disease and chronic bronchitis. [PDF]

open access: yes, 2010
The syndrome of chronic obstructive pulmonary disease (COPD) consists of chronic bronchitis (CB), bronchiectasis, emphysema, and reversible airway disease that combine uniquely in an individual patient.

Dual‐Pedicle Tissue‐Engineered Trachea Promotes Biomimetic Cartilaginous Framework, Vascularization, and Epithelial Lining for Long‐Segment Tracheal Reconstruction

open access: yesAdvanced Science, EarlyView.
Overcoming the limitations of conventional grafts, a biomimetic trachea with two independent vascular pedicles enables rapid integration and sustained patency. This approach markedly improves survival rates, restores the epithelial barrier, and promotes regenerative pathways, presenting a transformative paradigm for clinical application.

Conversion Therapy for cT4b and M1 Esophageal Squamous Cell Carcinoma: A Comprehensive Systematic Review

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
We systematically reviewed conversion therapy for esophageal squamous cell carcinoma and propose a response‐based treatment strategy for cT4b and M1 disease. For cT4b, we emphasize definitive chemoradiotherapy with timed re‐evaluation and selective salvage or chemoselection to surgery; for M1, conversion is reserved for limited‐burden responders with ...
