Adsorption and Vibrational Study of Folic Acid on Gold Nanopillar Structures Using Surface-enhanced Raman Scattering Spectroscopy [PDF]
This paper presents a study of adsorption and vibrational features of folic acid, using surface-enhanced Raman scattering (SERS). A gold-capped silicon nanopillar (Au NP) with a height of 600 nm and a width of 120 nm was utilized to study the vibrational

Chroman-4-One Derivatives Targeting Pteridine Reductase 1 and Showing Anti-Parasitic Activity [PDF]
Flavonoids have previously been identified as antiparasitic agents and pteridine reductase 1 (PTR1) inhibitors. Herein, we focus our attention on the chroman-4-one scaffold.

Pteridines in the Assessment of Neoplasia [PDF]
Biological processes which might explain the association of pteridine excretion with proliferation are still unknown. Difficulties in the analysis and the determination of naturally occurring pteridines are described. The best quantitative estimations were achieved when measurement of non-reduced forms was attempted.

In the vasculature, a physiologic production of nitric oxide (NO) is maintained by endothelial nitric oxide synthase (eNOS). Induction of inducible nitric oxide synthase (ÍNOS) under inflammatory conditions (e.g. septic shock) resulting in high levels of

Tetrahydrobiopterin analogues with NO-dependent pulmonary vasodilator properties [PDF]
Reduced NO levels due to the deficiency of tetrahydrobiopterin (BH4) contribute to impaired vasodilation in pulmonary hypertension Due to the chemically unstable nature of BH4 it was hypothesised that oxidatively stable analogues of BR, would be able to ...

Analysis by RNA-seq of transcriptomic changes elicited by heat shock in Leishmania major [PDF]
Besides their medical relevance, Leishmania is an adequate model for studying post-transcriptional mechanisms of gene expression. In this microorganism, mRNA degradation/stabilization mechanisms together with translational control and post-translational ...

1H-Benzo[g]pteridine-2,4-dione
The structure of the title compound, C10H6N4O2, reported by Smalley et al. [(2021). Cryst. Growth Des. 22, 524–534] from powder diffraction data and 15N NMR spectroscopy, is confirmed using low-temperature data from a twinned crystal. The tautomer in the

Sequence-Based Mapping and Genome Editing Reveal Mutations in Stickleback Hps5 Cause Oculocutaneous Albinism and the casper Phenotype. [PDF]
Here, we present and characterize the spontaneous X-linked recessive mutation casper, which causes oculocutaneous albinism in threespine sticklebacks (Gasterosteus aculeatus).
