Tough pitch copper wire (99.97% Cu) is generally characterized by the spiral elongation number. The principle of the test is based on the influence of impurities on the recrystallization kinetics. Alternative non-metallographic techniques to characterize the recrystallization kinetics have been investigated in this study, such as differential scanning(More)
The neurotransmitter dopamine (DA) is important for numerous biological functions, including control of movement. Oxidation of DA to highly toxic and reactive species has been hypothesized to contribute to the selective neurodegeneration observed in Parkinson's disease (PD). DA catabolism is initiated by oxidative deamination via monoamine oxidase to yield(More)
Regulator of G Protein Signaling (RGS) 17 is an overexpressed promoter of cancer survival in lung and prostate tumors, the knockdown of which results in decreased tumor cell proliferation in vitro. Identification of drug-like molecules inhibiting this protein could ameliorate the RGS17's pro-tumorigenic effect. Using high-throughput screening, a chemical(More)
3,4-Dihydroxyphenylacetaldehyde (DOPAL) is an endogenously produced toxic aldehyde. It is a bifunctional electrophile implicated in the loss of dopaminergic cells concomitant with Parkinson's disease and neurodegeneration. DOPAL is known to react with proteins and amino acids such as N-acetyl lysine (NAL); oxidation of the catechol moiety to the quinone of(More)
