Activated platelets secrete a negatively charged polymer, polyphosphate (polyP). Here, we explore the interactions of polyP with fibrin(ogen) and its effect on fibrin structure and fibrinolysis. Electrophoretic mobility and binding assays indicate that polyP interacts with fibrinogen and soluble fibrin. Clots formed in the presence of polyP exhibited reduced turbidity and permeability indicativ...

OBJECTIVE Endobronchial ultrasound-guided transbronchial needle aspiration could be performed better with computer-based preparation. METHODS Three-dimensional virtual bronchoscopy was used to develop 2 modes of computer-based "virtual endobronchial ultrasound." "Virtual endobronchial ultrasound standard" used conventional virtual bronchoscopy to determine the spot and angle for transbronchia...

BACKGROUND Current staging system for small cell lung cancer (SCLC) categorizes patients into limited- or extensive-stage disease groups according to anatomical localizations. Even so, a wide-range of survival times has been observed among patients in the same staging system. This study aimed to identify whether endobronchial mucosa invasion is an independent predictor for poor survival in pati...

To compare the performance of convex probe endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) with conventional endobronchial biopsy (EBB) or transbronchial lung biopsy (TBLB) in patients with mediastinal, and coexisting endobronchial or peripheral lesions.Retrospective review of records of patients undergoing diagnostic EBUS-TBNA and conventional bronchoscopy in 2014....

OBJECTIVE Endobronchial ultrasound elastography is a new technique for describing the stiffness of tissue during endobronchial ultrasound-guided transbronchial needle aspiration. The aims of this study were to evaluate the utility of endobronchial ultrasound elastography for mediastinal and hilar lymph nodes, and to compare the elastographic patterns of lymph nodes with results from endobronchi...

Endobronchial tuberculosis is defined as a tuberculous infection of the tracheobronchial tree and has a prevalence of up to 50% in active pulmonary tuberculosis cases. The most common complication of endobronchial tuberculosis is bronchial stenosis; benign fistula formation by endobronchial tuberculosis is rare, especially inter-bronchial fistula formation. We reported a rare case of a 73-year-...

A 72-year-old man was referred to our hospital with an endobronchial mass spotted on chest computed tomography (CT). On examination, he was afebrile, but complained of cough and sputum. Laboratory test results were normal. His chest CT showed an ovoid fat attenuation nodule in the left upper lobe bronchus (Fig. 1A). Flexible bronchoscopy was performed to investigate the endobronchial lesion, an...

Radiation therapy has emerged as a useful alternative therapy for patients with early-stage, non-resectable lung cancer. In patients whose malignancies are difficult to localize on computed tomography imaging, such therapy becomes difficult. Fiducial markers are frequently placed in peripheral pulmonary lesions to assist radiation therapy. Although placement of markers under linear endobronchia...
