Rome IV. Gallbladder and Sphincter of Oddi Disorders.

Gastroenterology

Cotton PB, Elta GH, Carter CR, Pasricha PJ, Corazziari ES.
PMID: 27144629
Gastroenterology. 2016 Feb 19; doi: 10.1053/j.gastro.2016.02.033. Epub 2016 Feb 19.

The concept that motor disorders of the gallbladder, cystic duct and sphincter of Oddi can cause painful syndromes is attractive and popular, at least in the USA. However, the results of commonly performed ablative treatments (cholecystectomy and sphincterotomy) are...

Practice patterns and perceptions of survivorship care in Canadian genitourinary oncology: A multidisciplinary perspective.

Canadian Urological Association journal = Journal de l'Association des urologues du Canada

Can Urol Assoc J. 2014 Nov;8(11):409-17. doi: 10.5489/cuaj.2279.

INTRODUCTION: There is little knowledge of survivorship care specific to genitourinary (GU) cancers. To improve care delivery to this patient population, we need to clearly define physician perceptions of survivorship care. We therefore conducted a study to determine the...

Ab initio structural and spectroscopic study of HPS(x) and HSP(x) (x = 0,+1,-1) in the gas phase.

The Journal of chemical physics

Ben Yaghlane S, Cotton CE, Francisco JS, Linguerri R, Hochlaf M.
PMID: 24206304
J Chem Phys. 2013 Nov 07;139(17):174313. doi: 10.1063/1.4827520.

Accurate ab initio computations of structural and spectroscopic parameters for the HPS/HSP molecules and corresponding cations and anions have been performed. For the electronic structure computations, standard and explicitly correlated coupled cluster techniques in conjunction with large basis sets...

Problems and solutions in delivering global surgery in the 21st century.

Br J Surg. 2016 Feb;103(3):165-9. doi: 10.1002/bjs.9961. Epub 2015 Dec 14.

BACKGROUND: Surgery has had low priority in global health planning, so the delivery of surgical care in low- and middle-income countries is often poorly resourced. A recent Lancet Commission on Global Surgery has highlighted the need for change.METHODS: A...

Oxidative scission of a Mo-Mo quadruple bond.

Inorganic chemistry

Two compounds containing the cations Mo2(DPhIP)4n+, n = 1 or 2 and DPhIP = the anion of 2,6-diphenyliminopiperidine, have been obtained by oxidation of the quadruply-bonded Mo2(DPhIP)4 species. The first oxidation process conserves the structure but results in a...

The anion of 2,6-di(phenylimino)piperidine (DPhIP) has been found to support linear chains of three metal atoms. Three new compounds, [Cr3(DPhIP)4Cl]Cl.(1).5CH2Cl2.0.5H2O (1.1.5CH2Cl2.0.5H2O), [Cr3(DPhIP)4(CH3CN)]- (PF6)2.H2O.4CH3CN (2.H2O.4CH3CN), and [Cr3(DPhIP)4(F)(CH3CN)](BF4)2.5CH3CN (3.5CH3CN), have been synthesized and characterized by X-ray crystallography. Compound 1 has a...

PMID: 11209603
Inorg Chem. 2001 Jan 29;40(3):472-7. doi: 10.1021/ic0010151.

Four compounds consisting of molecular loops formed from two quadruply bonded Mo2(DAniF)2 (DAniF = N,N'-di-p-anisylformamidinate) units linked by two dicarboxylate anions have been prepared in high purity and essentially quantitative yields. These compounds have been characterized by crystallography and...

Inorg Chem. 2002 May 06;41(9):2466-70. doi: 10.1021/ic025508c.

A systematic search of the Cambridge Crystallographic Database has yielded structures of 467 molecules containing, or reported to contain, a molybdenum to molybdenum quadruple bond, Mo[quadruple bond]Mo. We have arranged these data as a histogram, in order to determine...
