INTRODUCTION: During laparoscopic cholecystectomy (LC), common bile duct (CBD) visualization either directly or with cholangiography (IOC) is less routine. Cholangiography can be used to identify and possibly prevent bile duct injury (BDI), which is a dreaded complication of cholecystectomy. The purpose of our study was to evaluate the trend of IOC/CBD exploration and BDI during LC for benign disease. METHODS: A state-wide database (SPARCS) was used to identify all LC for benign biliary non-obstructive and obstructive disease between 2000 and 2014 in the state of New York...

Secreted protein acidic and rich in cysteine (SPARC) is a secreted protein which is involved in various biological processes. SPARC expression is associated with tumor metastasis and poor prognosis in several types of cancer. However, the SPARC-induced signaling pathway was not fully understood in head and neck cancer. In this study, our results showed that SPARC treatment promoted cell proliferation and migration in head and neck cancer cell lines FaDu and Detroit 562. In addition, SPARC induced expression of epithelial mesenchymal transition (EMT) regulators, including Slug, Snail, and Twist in Detroit 562...

Fibrotic stroma and tumor-promoting pancreatic stellate cells (PSCs), critical characters in the pancreatic ductal adenocarcinoma (PDA) microenvironment, promote a tumor-facilitating environment that simultaneously prevents drug penetration into tumor foci and stimulates tumor growth. Nab-PTX, a human serum albumin (HSA) nanoparticle of paclitaxel (PTX), indicates enhanced matrix penetration in PDA probably due to its small size in vivo and high affinity of HSA with secreted protein acidic and rich in cysteine (SPARC), overexpressed in the PDA stroma...
