Current opinion in gastroenterology

van Lanschot JJ, Aleman BM, Richel DJ.
PMID: 17033326
Curr Opin Gastroenterol. 2002 Jul;18(4):490-5. doi: 10.1097/00001574-200207000-00015.

Several new developments in the potentially curative therapy of esophageal cancer have drawn attention over the past year. There is a potential benefit of centralization of esophagectomies in dedicated centers. Early mucosal lesions are increasingly treated by local ablative...

Rehabilitation (Stuttg). 2009 Aug;48(4):211-21. doi: 10.1055/s-0029-1231062. Epub 2009 Aug 17.

BACKGROUND: Due to specifications in Social Code Book IX and increasing ICF orientation, occupation-related treatment gains importance in medical rehabilitation. The quick and easy identification of patients in need of occupational rehabilitation requires adequate screening instruments. The present study...

Glucocorticoids Decrease Hippocampal and Prefrontal Activation during Declarative Memory Retrieval in Young Men.

Brain Imaging Behav. 2007 Jun;1(1):31-41. doi: 10.1007/s11682-007-9003-2. Epub 2007 Jun 01.

Glucocorticoids (GCs, cortisol in human) are associated with impairments in declarative memory retrieval. Brain regions hypothesized to mediate these effects are the hippocampus and prefrontal cortex (PFC). Our aim was to use fMRI in localizing the effects of GCs...

Chemistry. 2011 Apr 04;17(15):4166-76. doi: 10.1002/chem.201003462. Epub 2011 Mar 04.

The paramagnetic dinuclear complexes 1,8-bis(cobaltocenyl)naphthalene (2) and 1,8-bis[(pentamethyl-η(5)-cyclopentadienyl)(η(5)-cyclopentadiendiyl)cobalt(II)]naphthalene (4) were synthesized. The molecular structures were characterized by X-ray structure analysis and consisted of two cobaltocenes linked through a distorted naphthalene clamp. Electronic interactions between the two cobalt atoms were...

Attempts to prepare the hitherto unknown Se(6)(2+) cation by the reaction of elemental selenium and Ag[A] ([A](-) = [Sb(OTeF(5))(6)](-), [Al(OC(CF(3))(3))(4)](-)) in SO(2) led to the formation of [(OSO)Ag(Se(6))Ag(OSO)][Sb(OTeF(5))(6)](2)1 and [(OSO)(2)Ag(Se(6))Ag(OSO)(2)][Al(OC(CF(3))(3))(4)](2)2a. 1 could only be prepared by using bromine as...

In the title complex, [Au(C(12)H(8)N(5)O(4))(C(18)H(15)P)], the coordination geometry about the Au(I) ion is linear, with one deprotonated 1,3-bis(4-nitrophenyl)triazenide ion, [O(2)NC(6)H(4)N=N-NC(6)H(4)NO(2)](-), acting as a monodentate ligand (two-electron donor), and one neutral triphenylphosphine molecule completing the metal coordination. The triazenide ligand...
