Unraveling cartilage degeneration through synergistic effects of hydrostatic pressure and biomimetic temperature increase

Dominique Pioletti, Peyman Karami, Naser Nasrollahzadeh Mamaghani, Theofanis Stampoultzis, Yanheng Guo, Vijay Kumar Rana

Cartilage degeneration, typically viewed as an irreversible, vicious cycle, sees a significant reduction in two essential biophysical cues: the well-established hydrostatic pressure (HP) and the recently discovered transient temperature increase. Our study ...

Epiphyseal chondro-progenitors provide a stable cell source for cartilage cell therapy

Dominique Pioletti, Corinne Scaletta, Salim Elias Darwiche

Articular cartilage regeneration poses particularly tough challenges for implementing cell-‐based therapies. Many cell types have been investigated looking for a balanced combination of responsiveness and stability, yet techniques are still far from defin ...

Size effects in indentation of hydrated biological tissues

Matteo Galli

Fluid flow in biological tissues is important in both mechanical and biological contexts. Given the hierarchical nature of tissues, there are varying length scales at which time-dependent mechanical behavior due to fluid flow may be exhibited. Here, spheri ...

Synthesis of C-linked Disaccharides and Analogues as Biomimetics of the TF Epitope

Maria Kolympadi

Glycoproteins and glycolipids are major components of the outer surface of mammalian cells. Their carbohydrate moieties, which are directed into the outer environment, serve as ligands for receptor proteins, such as lectins, pathogen proteins and antibodie ...

Pattern-Based Sensing of Sulfated Glycosaminoglycans with a Dynamic Mixture of Iron Complexes

Kay Severin

A dynamic mixture of iron complexes was used as a colorimetric sensor for sulfated glycosaminoglycans. The sensing ensemble was prepared by mixing [FeCl2(H2O)4] with dipicolylamine, the functionalized bipyridyl ligand N-(6-aminohexyl)-4'-methyl-2,2'-bipyri ...

Isolation and in vitro chondrogenic potential of human fetal spine cells

Dominique Pioletti, Corinne Scaletta, Sandra Jaccoud, Aurélie Quintin

Cell therapy for nucleus pulposus regeneration is an attractive treatment for early disc degeneration as shown by studies using autologous nucleus pulposus cells or stem cells. Another potential source of cells is fetal cells. We investigated the feasibili ...

C(1 -> 4)-linked disaccharides through carbonylative Stille cross-coupling

Pierre Vogel

A tinglucal tributyl[4,6-O-bis(t-butyl)silylidene-3-O-tris(isopropyl)silyl]tin 7 and a triflate derived from isolevoglucosenone (1R,4R,5R)-4-benzyloxy-6,8-dioxabicyclo[3.2.1]oct-2-en-2-yl trifluoromethanesulfonate 10 undergo the carbonylative Stille conden ...

Synthesis of C-glycosides and C-linked disaccharides through carbonylative Stille coupling reactions

Peter Steunenberg

In the first part, we described the synthesis of C-(1'→1) and C-(1'→4) disaccharide precursors, which are readily obtained via the carbonylative Stille coupling of glucal and isolevoglucosenone derivatives. Tin glycals and triflates, derived from isolevogl ...

Selective growth of mucolytic bacteria including Clostridium perfringens in a neonatal piglet model of total parenteral nutrition

Bart Deplancke

BACKGROUND: Compromised barrier function and intestinal inflammation are common complications of total parenteral nutrition (TPN). OBJECTIVE: We tested the hypothesis that the lack of enteral nutrients in TPN might select commensal or pathogenic bacteria t ...

Synthesis of the C-disaccharide alpha-C(1 -> 3)-L-fucopyranoside of N-acetylgalactosamine

Pierre Vogel

Radical C-glycosidation of racemic 5-exo-benzeneselenyl-6-endo-chloro-3-methylidene-7-oxabicyclo[2.2.1]hept an-2-one ((+/-)-2) with alpha -acetobromofucose (3) provided a mixture of alpha -C-fucosides that were reduced with NaBH4 to give two diastereomeric ...
