Selective bond-breaking in formic acid by dissociative electron attachment. [PDF]

open access: yes, 2020
We report the results of a joint experimental and theoretical study of dissociative electron attachment to formic acid (HCOOH) in the 6-9 eV region, where H- fragment ions are a dominant product.

The short- and long-term effects of formic acid on rapid nitritation start-up

open access: yesEnvironment International, 2020
The feasibility of achieving stable nitritation inoculating with activated sludge by adding formic acid was studied in this work. Short-term batch effects of formic acid on nitrification showed that the nitrite accumulation ratio (NAR) significantly ...

Quantification of Plasma and Urine Thymidine and 2'-Deoxyuridine by LC-MS/MS for the Pharmacodynamic Evaluation of Erythrocyte Encapsulated Thymidine Phosphorylase in Patients with Mitochondrial Neurogastrointestinal Encephalomyopathy. [PDF]

open access: yes, 2020
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an ultra-rare disorder caused by mutations in TYMP, leading to a deficiency in thymidine phosphorylase and a subsequent systemic accumulation of thymidine and 2'-deoxyuridine.

Biochemistry Changes That Occur after Death: Potential Markers for Determining Post-Mortem Interval [PDF]

open access: yes, 2013
Death is likely to result in very extensive biochemical changes in all body tissues due to lack of circulating oxygen, altered enzymatic reactions, cellular degradation, and cessation of anabolic production of metabolites.

The reaction of formic acid with RaneyTM copper [PDF]

open access: yes, 2016
The interaction of formic acid with RaneyTM Cu proves to be complex. Rather than the expected generation of a monolayer of bidentate formate, we find the formation of a Cu(II) compound. This process occurs by direct reaction of copper and formic acid; in
