Cinnamomum verum is used to make the spice cinnamon and has been used as a traditional Chinese herbal medicine. We evaluated the effects and the molecular mechanisms of cuminaldehyde (CuA), a constituent of the bark of Cinnamomum verum, on human lung squamous cell carcinoma NCI-H520 cells. Specifically, cell viability was evaluated by colorimetric assay;(More)
OBJECTIVE The study aimed to assess the clinical efficacy of pigtail catheter drainage for patients with a first episode of secondary spontaneous pneumothorax (SSP) and different associated conditions. METHODS We retrospectively reviewed the records of patients with SSP who received pigtail catheter drainage as their initial management between July 2002(More)
BACKGROUND Spontaneous bacterial empyema (SBE) is a complication of cirrhotic patients in which a pre-existing pleural effusion becomes infected. This retrospective study was designed to investigate the bacteriology and outcome predictors of SBE in cirrhotic patients. METHODS Medical records of cirrhotic patients treated in a tertiary care university(More)
A previous study, with relatively small number of patients, showed that prior Mycobacterium tuberculosis (TB) may precipitate SLE in patients from endemic areas. The purpose of the study was to investigate the relationship between prior TB infection and systemic lupus erythematosus (SLE) from the National Health Insurance Research Database (NHIRD) in(More)
OBJECTIVES To analyze the causative pathogens and outcomes of patients with thoracic empyema admitted to the medical intensive care unit (MICU) and medical ward. METHODS We prospectively studied the empyemic patients in the MICU and retrospectively analyzed the medical records of empyemic patients in the medical ward treated in a tertiary university(More)
Tracheobronchial foreign body (FB) aspiration is a common problem worldwide, and the aspired objects can be very difficult to remove. Bronchoscopic removal of airway FBs can be safely accomplished with both rigid as well as flexible bronchoscopes. It is well known that a rigid bronchoscope more easily removes large FBs located in the central bronchi. A wide(More)
OBJECTIVE Little is known about the efficacy and safety of ultrasound-guided pigtail catheters for the management of various pleural diseases in the emergency department, ward, and intensive care unit. METHODS We conducted a retrospective study in a university hospital during a 1-year interval. RESULTS A total of 276 patients (178 men and 98 women)(More)
The ankyrin repeat domain 49 (ANKRD49) is an evolutionarily conserved protein highly expressed in testes. However, the function of ANKRD49 in spermatogenesis is unknown. In this study, we found that ANKRD49 resides primarily in nucleus of spermatogonia, spermatocytes and round spermatids. ANKRD49 overexpression augments starvation-induced autophagy in male(More)
BACKGROUND Cinnamomum verum is used to manufacture the spice cinnamon. In addition, the plant has been used as a Chinese herbal medication. METHODS We investigated the antiproliferative effect of 2-methoxycinnamaldehyde (2-MCA), a constituent of the cortex of the plant, and the molecular biomarkers associated with tumorigenesis in human colorectal(More)
