(7R,8S,9S,12S)-1-Benzyloxy-13,14-didehydro-12-hydroxy-2,13-dimethoxy-N-methylmorphinane

open access: yesActa Crystallographica Section E, 2011
In the title compound, C26H31NO4, a sinomenine derivative, the angle between the two aromatic rings is 53.34 (4)°. The N-containing ring is in a chair conformation, while the other two non-planar rings are in a half-boat conformation ...

Detection of circulating tumor DNA in colorectal cancer patients using a methylation‐specific droplet digital PCR multiplex

open access: yesMolecular Oncology, EarlyView.
We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.

4,8,9,10-Tetrakis(4-fluorophenyl)-1,3-diazatricyclo[3.3.1.1]decan-6-one

open access: yesActa Crystallographica Section E, 2009
In the title compound, C32H24F4N2O, all four six-membered rings that constitute the diazaadamantanone cage adopt chair conformations. Two of the four fluorophenyl substituents occupy axial positions and the other two occupy equatorial positions relative ...

Crystal structure of 4,6-bis[(E)-4-bromostyryl]-2-(butylsulfanyl)pyrimidine

open access: yesActa Crystallographica Section E, 2014
In the title compound, C24H22Br2N2S, the dihedral angles between the central pyrimidine ring and the pendant bromobenzene rings are 11.02 (11) and 13.20 (12)°. The butyl side chain adopts a gauche conformation [C—C—C—C = −67.4 (4)°]. In the crystal, weak

Quotient rings, chain conditions and injective ring endomorphisms [PDF]

open access: yesGlasgow Mathematical Journal, 1989
In this paper, the situation we shall be concerned with is that of a ring R, with a ring monomorphism α: R → R, which will not be assumed to be surjective.Much work has been done on the skew polynomial ring R[x, α] and the skew Laurent polynomial ring R[x, x-1, α], where α is an automorphism—see [3] for example.

open access: yes
The purpose of this paper is to study codes over finite principal ideal rings. To do this, we begin with codes over finite chain rings as a natural generalization of codes over Galois rings GR(pe, l) (including Zpe).

Monitoring of circulating tumor DNA allows early detection of disease relapse in patients with operable breast cancer

open access: yesMolecular Oncology, EarlyView.
Monitoring circulating tumor DNA (ctDNA) in patients with operable breast cancer can reveal disease relapse earlier than radiology in a subset of patients. The failure to detect ctDNA in some patients with recurrent disease suggests that ctDNA could serve as a supplement to other monitoring approaches.

1,5-Bis(4-nitrophenoxy)pentane

open access: yesActa Crystallographica Section E, 2009
The title compound, C17H18N2O6, crystallizes with two molecules in the asymmetric unit. In both molecules, one of the C—C bonds of the pentamethylene chain connecting the two aromatic rings is in a trans conformation and another displays a ...
