Collagen overglycosylation: a biochemical feature that may contribute to bone quality.

2005

Skeletal ability to resist mechanical stress is determined by bone amount and quality, which relies on macro- and micro-architecture, turnover, bone matrix, and mineralisation; the role of collagen has not been clearly elucidated. Numerous post-translational steps are involved in collagen type I biosynthesis, including residue hydroxylation and glycosylation catalysed by enzymes that work until the protein folds forming the triple helix; therefore, folding rate regulates these processes. Overglycosylated hydroxylysines are poor substrates for epsilon-amino group deamination which initiates cross-link formation. Three clinical conditions associated with fractures may relate collagen overglyc…

Effective conjugation in conjugated polymers with strongly twisted backbones: A case study on fluorinated MEHPPV

2016

Conjugated polymers with strongly twisted backbones, such as MEHPPV with fluorinated vinylene units (F-MEHPPV), demand a redefinition of the all-important ‘effective conjugation length’ ECL, which we extract here by a facile graphical method. In MEHPPV (being essentially planar), the ECL coincides with the ‘maximum conducive chain length’ MCC and extends over about n ≈ 9 repetition units (RU). In F-MEHPPV, the MCC is similarly long with n ≈ 8, but the ECL localizes on just one RU. The strong twist in F-MEHPPV persists in the excited state, broadening the emission spectrum and quenching the fluorescence with reduced radiative and enhanced non-radiative rates.

Zebrafish Fins as a Model System for Skeletal Human Studies

2007

Recent studies on the morphogenesis of the fins ofDanio rerio(zebrafish) during development and regeneration suggest that a number of inductive signals involved in the process are similar to some of those that affect bone and cartilage differentiation in mammals and humans. Akimenko et al. (2002) has shown that bone morphogenetic protein-2b (BMP2b) is involved in the induction of dermal bone differentiation during fin regeneration. Many other groups have also shown that molecules from the transforming growth factor-beta superfamily (TGFβ), including BMP2, are effective in promoting chondrogenesis and osteogenesisin vivoin higher vertebrates, including humans. In the present study, we review…

Langer-Giedion syndrome with interstitial 8q-deletion.

1982

We describe a 12-year-old girl with Langer-Giedion syndrome (tricho-rhino-phalangeal syndrome type II) who also had vertebral malformations. Chromosome analysis identified an interstitial del(8q): 46,XX,del(8)(pter leads to q22::q234 leads to qter) as a cause of this syndrome.

The C-ORAL-BRASIL project for Brazilian Portuguese spoken corpora

2020

En aquest article presentem un subconjunt de corpus orals de la família C-ORAL, concretament, el corpus C-ORAL-BRASIL de portuguès brasiler espontani (PB). Derivat de la branca no-europea del projecte C-ORAL-ROM (Cresti i Moneglia 2005), el projecte C-ORAL-BRASIL ha aplegat uns corpus orals de PB de tercera generació, el qual destaca no sols com a corpus de PB, sinó també com una bona eina per a l’estudi de la llengua parlada en general, gràcies a algunes millores metodològiques i tecnològiques. A més dels recursos per a l’estudi del PB oral, presentem un conjunt de minicorpus creats per a l’estudi específic de l’estructura informativa (també en altres llengües a més del PB); així mateix, t…

Reconstruction of human subsistence and husbandry strategies from the Iberian Early Neolithic: A stable isotope approach

2018

Objectives The Early Neolithic involved an important social and economic shift that can be tested not only with the material culture, but also through biomolecular approaches. The Iberian Peninsula presents few Early Neolithic sites where fauna and humans can be analyzed together from an isotopic perspective. Here we present an isotopic study on the site of Cueva de Chaves as an example for understanding the dietary and economical changes that took place during Early Neolithic in Iberia. Material and methods Here we apply carbon and nitrogen stable isotope analysis to bone collagen from 4 humans and 64 faunal samples from 14 different species. The large dataset belongs to the same unique ch…

<strong><em>Chilocoris laevicollis</em> Horváth, 1919, and<em> Ch. umbricola</em> Linnavuori, 1993—two trogloxenic burr…

2016

First country records of two burrower bugs, Chilocoris laevicollis , and Ch . umbricola (Hemiptera: Heteroptera: Cydnidae) from Gabon (Central Africa) are presented. The study was based on the specimens collected by Dr. V. Aellen, a well-known Swiss speleologist, taken from two caves near Lastoursville in the Gabonese Republic. Diagnostic characters for both recorded species are provided, and data on their biology and distribution are summarized.
