[Therapeutic education, a source of inspiration for students].

Therapeutic education contributes to improving the health of patients suffering from chronic diseases, their quality of life and that of their loved ones. It is complementary and inseparable from treatment and care, symptom relief and prevention of complications. Inspired by the modalities of this approach towards children suffering from cystic fibrosis, students from a nursing training institute in Ile-de-France share their work on this theme.

The evolving practice of developmental care in the neonatal unit: a systematic review.

Many neonatal intensive care units (NICUs) are experiencing changes in their approaches to preterm infant care as they consider and incorporate the philosophy of individualized developmental care. The aim of this systematic review is to research current literature documenting the short-term effects of developmental care and the Newborn Individualized Developmental Care and Assessment Program (NIDCAP). The following databases were reviewed: PubMED, CINAHL, and PsychINFO by using the keywords developmental care, individualized care, preterm infant, early intervention, and NIDCAP.

Rv3389C from Mycobacterium tuberculosis, a member of the (R)-specific hydratase/dehydratase family.

The (R)-specific 3-hydroxyacyl dehydratases/trans-enoyl hydratases are key proteins in the biosynthesis of fatty acids. In mycobacteria, such enzymes remain unknown, although they are involved in the biosynthesis of major and essential lipids like mycolic acids. First bioinformatic analyses allowed to identify a single candidate protein, namely Rv3389c, that belongs to the hydratases 2 family and is most likely made of a distinctive asymmetric double hot dog fold.

Antigen-induced TCR-CD3 down-modulation does not require CD3delta or CD3gamma cytoplasmic domains, necessary in response to anti-CD3 antibody.

We studied cytotoxic T lymphocyte (CTL) clones expressing cytoplasmic domain-deleted CD3delta and CD3gamma chains. These cells retained efficient antigen-specific cytolysis. Because the cytoplasmic domains of native CD3delta and CD3gamma chains contain a dileucine-based and a tyrosine-based motif thought to be important for receptor endocytosis, we compared TCR-CD3 down-modulation on the CTL clones expressing or not these domains.

Selection of phenotypically distinct NK1.1+ T cells upon antigen expression in the thymus or in the liver.

Unlike the main TCR alphabeta T cell lineage in which deletion occurs at the CD4+ CD8+ double-positive (DP) stage upon TCR engagement by antigen in the thymus, some T cells appear to require such engagement for their selection, either in the thymus or extrathymically. We used a transgenic TCR (tgTCR) model which, as we previously showed, led to selection upon expression of the corresponding antigen H-2Kb (Kb) in the thymus, of tgTCR/CD3(lo) CD4- CD8- double-negative (DN) thymocytes that expressed the NK1.1 marker (NK T cells) (Curnow, S.
