Melting of genomic DNA: predictive modeling by nonlinear lattice dynamics

open access: yes, 2010
The melting behavior of long, heterogeneous DNA chains is examined within the framework of the nonlinear lattice dynamics based Peyrard-Bishop-Dauxois (PBD) model.

Coexistence of two main folded G-quadruplexes within a single G-rich domain in the EGFR promoter [PDF]

open access: yes, 2017
EGFR is an oncogene which codifies for a tyrosine kinase receptor that represents an important target for anticancer therapy. Indeed, several human cancers showed an upregulation of the activity of this protein.

The conversion of citrulline to arginine in kidney [PDF]

open access: yes, 1941
Glycocyamine is formed in the kidney by the transfer of the amidine group of arginine to the nitrogen atom of glycine. In the study of this reaction it was observed that glycocyamine was also formed from citrulline and glycine.

Impaired nutrient signaling and body weight control in a Na⁺ neutral amino acid cotransporter (Slc6a19)-deficient mouse [PDF]

open access: yes, 2015
Amino acid uptake in the intestine and kidney is mediated by a variety of amino acid transporters. To understand the role of epithelial neutral amino acid uptake in whole body homeostasis, we analyzed mice lacking the apical broad-spectrum neutral (0 ...

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

open access: yesChemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Revisiting C4N4 Fluorophore: Theoretical Elucidation of the Origin of Fluorescent Properties of 2,5‐Diaminopyrimidines and Strategic Applications to Pd Detection

open access: yesChemistry – A European Journal, EarlyView.
A compact C4N4 fluorophore—comprising only four carbons and four nitrogens—shows structure‐dependent fluorescence that can be rationalized by TDDFT and AFIR analyses. Rational structural design controls whether emission is turned ON or OFF through computationally identified CI structures.

Nucleotides: Structure and Properties [PDF]

open access: yes, 2005
Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...
