Mordida cruzada posterior, correccion y consideraciones: caso clínico con 7 años de seguimiento
(Universidad Central de Venezuela, 2011)
Early treatment of functional unilateral posterior crossbite during the mixed dentition is extremely important for contemporary Orthodontics, provides the correct positioning of osseous bases, teeth and temporomadibular ...
Physical reasons for the unusual α-helix stabilization afforded by charged or neutral polar residues in alanine-rich peptides
(National Academy of Sciences, 2000-11)
We have carried out conformational energy calculations on alanine-based copolymers with the sequence Ac-AAAAAXAAAA-NH2 in water, where X stands for lysine or glutamine, to identify the underlying source of stability of ...

Hydration effects on DNA double helix stability modulates ligand binding to natural DNA in response to changes in water activity.
(2001-01-01)
In this work we present evidence that water molecules are actively involved on the control of binding affinity and binding site discrimination of a drug to natural DNA. In a previous study, the effect of water activity ...
A transmembrane histidine kinase functions as a pH sensor
(Multidisciplinary Digital Publishing Institute, 2020-08)
The two-component system DesK-DesR regulates the synthesis of unsaturated fatty acids in the soil bacteria Bacillus subtilis. This system is activated at low temperature and maintains membrane lipid fluidity upon temperature ...
On the difference in stability between horse and sperm whale myoglobins
(Elsevier Science IncNew YorkEUA, 2005)
A strained DNA binding helix is conserved for site recognition, folding nucleation, and conformational modulation
(John Wiley & Sons Inc, 2009-06)
Nucleic acid recognition is often mediated by alpha-helices or disordered regions that fold into alpha-helix on binding. A peptide bearing the DNA recognition helix of HPV16 E2 displays type II polyproline (PII) structure ...
Control of the Hypoxic Response in Drosophila melanogaster by the Basic Helix-Loop-Helix PAS Protein Similar
(American Society for Microbiology, 2002-10)
In mammalian systems, the heterodimeric basic helix-loop-helix (bHLH)-PAS transcription hypoxia-inducible factor (HIF) has emerged as the key regulator of responses to hypoxia. Here we define a homologous system in Drosophila ...

(Cellular & Molecular Biology, 2001-07-01)
In this work we present evidence that water molecules are actively involved on the control of binding affinity and binding site discrimination of a drug to natural DNA. In a previous study, the effect of water activity ...
