The Meishan section across the Permian-Triassic boundary in South China is the most thoroughly investigated in the world. A statistical analysis of the occurrences of 162 genera and 333 species confirms a sudden extinction event at 251.4 million years ago, coincident with a dramatic depletion of delta13C(carbonate) and an increase in microspherules.
BACKGROUND The purpose of the present study was to assess the value of matrix metalloproteinase (MMP)-2 and MMP-9 expression and other potential prognostic factors in predicting the clinical outcome of patients after definitive surgery for pathologic stage IA non-small cell lung cancer (NSCLC). METHODS One hundred and forty-six consecutive and(More)
OBJECTIVE Video-assisted thoracoscopic surgery (VATS) lobectomy has been gradually accepted as an alternative surgical approach to open thoracotomy for selected patients with non-small-cell lung cancer (NSCLC) over the past 20 years. The aim of this project was to standardize the perioperative management of VATS lobectomy patients through expert consensus(More)
OBJECTIVES This meta-analysis aimed to compare the perioperative outcomes of video-assisted thoracic surgery (VATS) with open thoracotomy for propensity score-matched patients with early-stage non-small cell lung cancer (NSCLC). METHODS Four relevant studies with propensity score-matched patients were identified from six electronic databases. Endpoints(More)
OBJECTIVES The present systematic review objectively assessed the safety and clinical effectiveness of transcatheter aortic valve implantation for patients at high surgical risk with severe aortic stenosis. METHODS Electronic searches were performed in 6 databases from January 2000 to March 2009. The end points included feasibility, safety, efficacy, and(More)
BACKGROUND Malignant pleural mesothelioma (MPM) is an aggressive disease of the pleural lining with a dismal prognosis. Surgical treatments of MPM with a curative intent include extrapleural pneumonectomy and extended pleurectomy/decortication (P/D). This meta-analysis aimed to compare the perioperative and long-term outcomes of EPP and extended P/D for(More)
Perioperative intraperitoneal chemotherapy in combination with cytoreductive surgery has been shown to be of benefit for treating selected patients with peritoneal surface malignancy. It has become a new standard of care in the management of diffuse malignant peritoneal mesothelioma and peritoneal dissemination of appendiceal malignancy. Numerous recent(More)
INTRODUCTION The primary objective of the present systematic review was to evaluate the safety and efficacy of extrapleural pneumonectomy (EPP) for patients with malignant pleural mesothelioma. METHODS A systematic review of relevant studies identified through five online search databases was performed. Two reviewers independently appraised each study. (More)
BACKGROUND (90)Y microsphere radioembolization is performed by injecting the microspheres through a hepatic artery catheter placed percutaneously via the femoral or brachial artery. This study assessed the efficacy of (90)Y microsphere therapy for patients with unresectable neuroendocrine tumour liver metastases (NETLMs). Potential prognostic factors were(More)
OBJECTIVES There is renewed interest in performing segmentectomies and wedge resections for selected patients with early-stage non-small cell lung cancer. However, comparative data on sublobar resections versus lobectomies include 'intentionally selected' patients who could tolerate either procedure, or 'compromised' patients who could only undergo sublobar(More)
