View Article and Find Full Text PDFEngineering of glycosyltransferases (GTs) with desired substrate specificity for the synthesis of complex oligosaccharides has been of great scientific and industrial interest. Here we describe an ultra-high-throughput fluorescence activated cell sorting (FACS) method for the directed evolution of GTs, at the single cell level. This assay relies on the exquisite substrate specificity of lactose permeases (LacY) that are located in the cell membrane, which distinguish selectively the fluorescent glycosylated products from the unreacted substrates.

Background: Banxia Xiexin Decoction (BXXD) reportedly regulates glycolipid metabolism and inhibits pancreatic -cell apoptosis. This study is aimed at investigating the protective effect of BXXD on -butyl hydroperoxide- (t-BHP-) induced apoptosis in MIN6 cells and the underlying mechanisms.
Methods: MIN6 cells were preincubated with BXXD or liraglutide (Li) with or without PI3K inhibitor LY294002 (LY) for 12 h, following which t-BHP was added to induce MIN6 cell apoptosis.
Fucosylated glycoconjugates are involved in a variety of physiological and pathological processes. However, economical production of fucosylated drugs and prebiotic supplements has been hampered by the poor catalytic efficiency of fucosyltransferases. Here, we developed a fluorescence-activated cell sorting system that enables the ultrahigh-throughput screening (>10 mutants/hour) of such enzymes and designed a companion strategy to assess the screening performance of the system.

However, the mechanism regulating the strict substrate specificity of these GH5 glycosidases has not been identified. In this study, we report a novel EGCase I from 103S (103S_EGCase I) with remarkably broad substrate specificity.
View Article and Find Full Text PDFBackground: Presently, several systems for the prognostication of pancreatic endocrine neoplasms (PENs) exist and the most appropriate classification system has not been clearly defined. This study aims to validate the performance of the 2004 World Health Organization (WHO), European Neuroendocrine Tumor Society (ENETS), Memorial Sloan-Kettering Cancer Center (MSKCC), American Joint Committee for Cancer (AJCC) TNM staging and Bilimoria criteria in a cohort of patients with PENs who underwent surgery at a single institution.
Methods: This study is a retrospective review of 61 consecutive patients who underwent surgical treatment for PEN.
Objectives: Whilst there are theoretical benefits from pre-operatively draining the biliary tree prior to pancreatoduodenectomy (PD), the current literature does not support this intervention. The aim of this study was to explore the relationship between pre-operative stenting, bactibilia and outcome in a large United Kingdom tertiary referral practice.
Methods: Patients undergoing PD were identified from a prospectively maintained database.
Cholangiocarcinoma (CC) and hepatocellularcarcinoma (HCC) are two main forms of liver malignancies, which exhibit differences in drug response and prognosis. Immunohistotochemical staining for cytokeratin markers has been used to some success in the differential diagnosis of CC from HCC. However, there remains a need for additional markers for increased sensitivity and specificity of diagnosis.

We report the results from a single institution experience whereby the management policy adopted was that of accurate preoperative localization before surgical exploration.
Materials And Methods: From 1990 to 2008, 17 patients with a clinical and biochemical diagnosis of an insulinoma who underwent surgery were retrospectively reviewed.
Objective: To critically analyze a large single-institution experience with distal pancreatectomy (DP), with particular attention to the risk factors, outcome, and management of the postoperative pancreatic fistula (PF).
Design: Retrospective study.
Setting: Tertiary referral center.
Objectives: To determine the outcome of patients undergoing distal pancreatectomy for pancreatic adenocarcinoma.
Methods: A retrospective review of 39 patients undergoing distal pancreatectomy for adenocarcinoma.
Results: Thirty patients underwent surgery for ductal adenocarcinoma, 5 for malignant intraductal papillary mucinous neoplasm and 4 for mucinous cystadenocarcinoma.
Background: This study aims to determine the use of preoperative clinical, biochemical, and cross-sectional imaging features for predicting malignancy in cystic lesions of the pancreas (CLP).
Study Design: Two hundred twenty patients who underwent operations for CLP or suspected CLP were reviewed. Patients were divided into two groups, patients undergoing operations for pseudocysts and patients undergoing operations for suspected cystic neoplasms.
Locally advanced squamous cell carcinoma of the tongue represents a significant therapeutic challenge. Novel methods using systemic chemotherapy with concurrent radiotherapy have been used to improve loco-regional response in patients who historically have poor prognosis. The simultaneous use of both modalities enhances planned local treatment by radiosensitization and potentially eradicates micrometastatic disease.
