Journal of community genetics

Cohn EG, Hamilton N, Larson EL, Williams JK.
PMID: 28623623
J Community Genet. 2017 Jul;8(3):229-238. doi: 10.1007/s12687-017-0308-6. Epub 2017 Jun 16.

Precision medicine envisions a future of effective diagnosis, treatment, and prevention grounded in precise understandings of the genetic and environmental determinants of disease. Given that the original genome-wide association studies represented a predominately European White population, and that diversity...

PMID: 11666851
Inorg Chem. 1996 Nov 06;35(23):6838-6843. doi: 10.1021/ic951604k.

The geometric structure of the confacial bioctahedral [Re(2)Cl(9)](z)()(-) anion has been determined by single-crystal X-ray diffraction in two distinct oxidation states, Re(IV)(2) and Re(III)Re(IV). [Bu(4)N][Re(2)Cl(9)] crystallizes in the monoclinic space group P2(1)/m [a/Å = 10.6363(3), b/Å = 11.420(1), c/Å...

Relatively little data exist on intermediate to late functional status and survival of patients after Fontan procedures. The first 500 patients undergoing a Fontan procedure at Children's Hospital (Boston, MA) were reviewed and then followed. There were 31 late...

Redox-Induced Formation and Cleavage of O-O sigma and pi Bonds in a Peroxo-Bridged Manganese Dimer: A Density Functional Study.

Inorganic chemistry

McGrady JE, Stranger R.
PMID: 11673961
Inorg Chem. 1999 Feb 08;38(3):550-558. doi: 10.1021/ic981253k.

The structural and electronic consequences of reduction and oxidation of a peroxo-bridged Mn(2)(IV/IV) dimer, Mn(2)(&mgr;-O)(2)(&mgr;-O(2))(NH(3))(6)(2+), are examined using approximate density functional theory. In both cases, the initial electron-transfer step is localized on the metal centers, but subsequent structural rearrangement...

Syntheses and Properties of Homoleptic Carbonyl and Trifluorophosphane Niobates: [Nb(CO)(6)](-), [Nb(PF(3))(6)](-) and [Nb(CO)(5)](3)(-) (,)(1).

PMID: 11670773
Inorg Chem. 1998 Dec 14;37(25):6518-6527. doi: 10.1021/ic980752i.

Reductive carbonylations of NbCl(4)(THF)(2), THF = tetrahydrofuran, mediated by sodium naphthalene in 1,2-dimethoxyethane, DME, or sodium anthracene in THF, provide [Nb(CO)(6)](-) as the tetraethylammonium salt in 60% or 70% isolated yields, respectively, the highest known for atmospheric pressure syntheses...

J Org Chem. 1997 May 02;62(9):2786-2797. doi: 10.1021/jo962358c.

The alpha-thiocarbocation generated from the Pummerer reaction of an o-amido-substituted sulfoxide is intercepted by the adjacent amido carbonyl group to produce a 2-amino-substituted isobenzofuran as a transient intermediate. In the presence of an electron-deficient dienophile, the reactive isobenzofuran undergoes...
