A Coordinated Clinical Center for Young Onset Colorectal Cancer.

The increase in young onset colorectal cancer and the complex care needs of young cancer patients spurred the development of the Center for Young Onset Colorectal Cancer at the Memorial Sloan Kettering Cancer Center. This article describes the lessons of the first 2 years at the Center, including development of the program and specific services provided.

WoCoVA consensus on the clinical use of in-line filtration during intravenous infusions: Current evidence and recommendations for future research.

The need for filtering intravenous infusions has long been recognized in the field of venous access, though hard scientific evidence about the actual indications for in-line filters has been scarce. In the last few years, several papers and a few clinical studies have raised again this issue, suggesting that the time has come for a proper definition of the type of filtration, of its potential benefit, and of its proper indications in clinical practice. The WoCoVA Foundation, whose goal is to increase the global awareness on the risk of intravenous access and on patients' safety, developed the project of a consensus on intravenous filtration.

Induction of cytotoxic T lymphocyte activity by fusion-active peptide-containing virosomes.

Priming of cytotoxic T lymphocyte (CTL) activity with exogenous antigen requires introduction of the antigen into the MHC class I presentation pathway of antigen-presenting cells. In the present study, we used fusogenic reconstituted envelopes (virosomes), derived from influenza virus, as a carrier system for delivery of a synthetic soluble peptide corresponding to a major murine CTL epitope of the influenza virus nucleoprotein (NP). Virosomes containing encapsulated NP-peptide efficiently sensitized target cells for recognition by influenza-specific CTLs generated through priming of mice with infectious virus.

Crystal structure of a murine alpha-class glutathione S-transferase involved in cellular defense against oxidative stress.

Glutathione S-transferases (GSTs) are ubiquitous multifunctional enzymes which play a key role in cellular detoxification. The enzymes protect the cells against toxicants by conjugating them to glutathione. Recently, a novel subgroup of alpha-class GSTs has been identified with altered substrate specificity which is particularly important for cellular defense against oxidative stress.

X-ray structure of antistasin at 1.9 A resolution and its modelled complex with blood coagulation factor Xa.

The three-dimensional structure of antistasin, a potent inhibitor of blood coagulation factor Xa, from the Mexican leech Haementeria officinalis was determined at 1.9 A resolution by X-ray crystallography. The structure reveals a novel protein fold composed of two homologous domains, each resembling the structure of hirustasin, a related 55-residue protease inhibitor.
