Molecular characterization and quantification using state of the art solid-state adiabatic TOBSY NMR in burn trauma
(D.A. Spandidos, 2009)
We describe a novel solid-state nuclear magnetic resonance (NMR) method that maximizes the advantages of high-resolution magic-angle-spinning (HRMAS), relative conventional liquid-state NMR approaches, when applied to ...
Using Topology of the Metabolic Network to Predict Viability of Mutant Strains
(BioMed Central, 2005)
Background: Understanding the relationships between the structure (topology) and function of biological networks is a central question of systems biology. The idea that topology is a major determinant of systems function ...
IgG4-associated cholangitis: a comparative histological and immunophenotypic study with primary sclerosing cholangitis on liver biopsy material
(Springer Nature, 2009)
IgG4-associated cholangitis is a steroid-responsive hepatobiliary inflammatory condition associated with autoimmune pancreatitis that clinically and radiologically mimics primary sclerosing cholangitis. In this study, we ...
En bloc esophageal mucosectomy for concentric circumferential mucosal resection (with video)
(Elsevier BV, 2009)
Background: With conventional EMR, specimens are fragmented, metaplasia may be left behind, and invasive lesions could be missed because of incomplete sampling. Concentric subtotal esophageal mucosectomy would address these ...
Serous Cystadenoma of the Pancreas: Limitations and Pitfalls of EUS Guided Fine Needle Aspiration Biopsy
(Wiley-Blackwell, 2008)
BACKGROUND: Expectant management of serous cystadenoma (SCA) of the pancreas requires an accurate preoperative diagnosis. Previously published cytologic diagnostic sensitivities have ranged widely, from 10% to 100%. In the ...
Autoimmune pancreatitis-related cholecystitis: a morphologically and immunologically distinctive form of lymphoplasmacytic sclerosing cholecystitis
(Wiley-Blackwell, 2009)
Aims: Gallbladder involvement in autoimmune pancreatitis (AIP) is reported to be histologically similar to that seen in primary sclerosing cholangitis (PSC) and biliary obstruction secondary to pancreatic ductal adenocarcinoma ...
Cell polarity protein Lgl2 is lost or aberrantly localized in gastric dysplasia and adenocarcinoma: an immunohistochemical study
(Springer Nature, 2009)
The diagnosis of gastric epithelial dysplasia, a precursor lesion of gastric adenocarcinoma, is hindered by interobserver variability and by its resemblance to regenerative changes. Loss of cell polarity, a histological ...
The Rectal Tonsil: A Reactive Lymphoid Proliferation That May Mimic Lymphoma
(Ovid Technologies (Wolters Kluwer Health), 2008)
The rectal tonsil (RT), a localized reactive proliferation of lymphoid tissue occurring in the rectum, can cause diagnostic difficulty; and awareness of this entity can prevent a misdiagnosis of lymphoma. A clinicopathologic ...
Salvinorin A and Derivatives: Protection from Metabolism Does Not Prolong Short-Term, Whole-Brain Residence
(Elsevier BV, 2009)
Salvinorin A (SA) is a potent kappa opioid agonist with a brief duration of action. Consistent with this, our previous positron emission tomography (PET) studies of carbon-11 labeled SA showed that brain levels decrease ...
One-Pot, Direct Incorporation of [11 C]CO 2 into Carbamates
(Wiley-Blackwell, 2009)
Why beat about the bush? An operationally simple and mild reaction based on the direct fixation of 11CO2 with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) has been developed for the synthesis of 11C-labeled carbamates at 75 °C ...
