DNA methylation/hydroxymethylation in melanoma

open access: yesOncotarget, 2017
Melanoma is a malignant tumor of melanocytes and is considered to be the most aggressive cancer among all skin diseases. The pathogenesis of melanoma has not been well documented, which may restrict the research and development of biomarkers and therapies.

Dynamic Hydrogen‐Bonding Nanonetworks and Asymmetric Dual‐Interface Built‐In Electric Fields Cooperatively Mediate Proton‐Coupled Electron Transfer for C─H Activation

open access: yesAdvanced Science, EarlyView.
The general strategy for constructing proton–electron dual‐transport‐channel photocatalysts (hollow Co3S4/Sv‐chalcogenide/Ti3C2 nanoreactors) is developed. Theses ternary‐component nanoreactors feature dynamic hydrogen‐bonding nanonetworks as proton‐transport channels and asymmetric dual‐interface BIEFs as electron‐transport channels, serving as a ...

Method of detecting and counting bacteria in body fluids [PDF]

open access: yes, 1973
A novel method is reported for determining bacterial levels in urine samples, which method depends on the quantitative determination of bacterial adenosine triphosphate (ATP) in the presence of non-bacterial ATP.

2-[2-(Hydroxymethyl)phenyliminomethyl]phenol

open access: yesActa Crystallographica Section E Structure Reports Online, 2004
Molecules of the title compound, C14H13NO2, are nearly planar. The molecular structure is stabilized by a strong intramolecular O—H⋯N hydrogen bond between the imine and hydroxyl groups [O⋯N = 2.614 (2) A]. In the crystal structure, intermolecular O—H⋯O hydrogen bonds [O⋯O = 2.681 (3) and 2.641 (3) A] link inversion-related mol­ecules into chains ...

Hachimoji DNA and RNA: A genetic system with eight building blocks [PDF]

open access: yes, 2019
Reported here are DNA and RNA-like systems built from eight (hachi-) nucleotide letters (-moji) that form four orthogonal pairs. This synthetic genetic biopolymer meets the structural requirements needed to support Darwinism, including a polyelectrolyte ...

Synthesis of 1-azaspiro[4.4]nonan-1-oxyls via intramolecular 1,3-dipolar cycloaddition

open access: yesBeilstein Journal of Organic Chemistry, 2019
Sterically shielded nitroxides of the pyrrolidine series have shown the highest resistance to reduction. Here we report the synthesis of new pyrrolidine nitroxides from 5,5-dialkyl-1-pyrroline N-oxides via the introduction of a pent-4-enyl group to the ...

Rapid intraoperative visualization of breast lesions with γ-glutamyl hydroxymethyl rhodamine green

open access: yesScientific Reports, 2015
We previously developed γ-glutamyl hydroxymethyl rhodamine green (gGlu-HMRG) as a tool to detect viable cancer cells, based on the fact that the enzyme γ-glutamyltranspeptidase (GGT) is overexpressed on membranes of various cancer cells, but is not ...

New ferrocene-derived hydroxymethylphosphines: FcP(CH₂OH)₂ [Fc=(η⁵-C₅H₅)Fe(η⁵-C₅H₄)] and the dppf analogue 1,1′-Fc′[P(CH₂OH)₂]₂ [Fc′=Fe(η⁵-C₅H₄)₂] [PDF]

open access: yes, 2001
Reactions of the ferrocene-phosphines FcPH₂ and 1,1′-Fc′(PH₂)₂ with excess formaldehyde gives the new hydroxymethylphosphines FcP(CH₂OH)₂ 1 and 1,1′-Fc′[P(CH₂OH)₂]₂ 2, respectively. Phosphine 1 is an air-stable crystalline solid, whereas 2 is isolated as
