Pseudopólipos inflamatorios en pacientes con enfermedad inflamatoria intestinal: correlación entre hallazgos macroscópicos y microscópicos, clasificación histológica e implicaciones clínicas
Los pseudopólipos inflamatorios (PPII) son lesiones no neoplásicas que aparecen como consecuencia de repetidos ciclos de inflamación y regeneración del epitelio colónico. Existen pocos estudios que analicen este tipo de lesiones, incluyendo sus características endoscópicas y anatomopatológicas. El …

Isomerization-Locked Alkene Analogues of Xaa–Pro Dipeptides in the Proteins Collagen and Bora
… of three left-handed polyproline type II (PPII helices) that intertwine around a common axis. Each PPII helix has the repeating peptide sequence (Gly–Xaa–Yaa)n with a high content of (2S)-proline (Pro) in the Xaa position (ca. 28%) and (2S,4R)-hydroxyproline (Hyp) in the Yaa position (ca. …

I. Collagen-like polypeptides. II. Helix-turn-helix peptides and turn mimetics
… in mammals. It consists of three left-handed PPII helixes coiled along a common axis to form a very compact right-handed super helix. The primary structure is shown to be (Gly-Xaa-Yaa)n repeats with high content of prolyl residues at both Xaa and Yaa positions. <i>Cis-trans</i> isomerization …

Elucidación de la auto-organización de la proteína gliadina y su péptido 33-mer in vitro
… en un equilibrio conformacional random coil/PPII y PPII/β paralela, dependiente de la concentración. Mediante dinámica molecular y distribución de cargas parciales fue posible observar que el péptido se comporta como una molécula anfifílica y es capaz de asociarse formando al menos un dímero …

Purification and characterization of A[beta] and probing the interactions between myricetin and A[beta] using various spectroscopic methods
… structure. A[beta](1-16) is predominantly PPII structure. Various spectroscopic methods were employed to investigate the binding interactions between disordered A[beta] and myricetin, one of the flavonoid compounds. A[beta]-myricetin complex formation was visualized by myricetin's intrinsic …

Oligomers of beta-L-arabinosides of hydroxyproline : synthesis of the carbohydrate epitope of the Art v 1 allergen
… 220 nm, ëmin = 200 nm) all exhibited significant PPII characteristics. Nuclear magnetic resonance spectroscopy was employed to fully characterize all synthetic glycopeptides. Spectra obtained from 1H, 13C, and various 2D NMR was used for comparison with NMR data taken from the natural allergen.

Organised Chaos: defining different degrees of intrinsic disorder by molecular dynamics methods
… increases the level of polyproline II (PPII) structure in the unbound peptides, which has been also recently underlined as an important in signalling pathways. In summary, I believe that this research work on a few examples of structurally disordered systems contributes to shed some …
