Chiral Lithium Amido Aryl Zincates: Simple and Efficient Chemo- and Enantio-Selective Aryl Transfer Reagents.

An enantioselective aryl transfer is promoted using chiral tricoordinated lithium amido aryl zincates that are easily accessible reagents and whose chiral appendage is simply recovered for reuse. The arylation reaction is run in good yields (60 % average on twenty substrates) and high enantiomeric excesses (95 % ee average). This occurs whatever the ortho, meta, or para substituent borne by the substrate and a complete chemoselectivity is observed with respect to the aldehyde function.

Allogeneic hematopoietic stem cell transplantation for acquired aplastic anemia using cyclophosphamide and antithymocyte globulin: a single center experience.

Between February 1998 and October 2007, 97 (69 male, 28 female) patients with acquired aplastic anemia and a median age of 18 years (range, 2-39) received related allogeneic hematopoietic stem cell transplantation. Ninety-five patients received bone marrow grafts and two patients G-CSF primed peripheral blood stem cell transplantation. The donors were genotypically HLA-identical siblings in 94 cases, HLA-matched parents in 2 cases and a syngeneic twin in 1 case.

Hemophagocytic syndrome after hematopoietic stem cell transplantation: a prospective observational study.

The aim of this prospective observational study was to evaluate the incidence of hemophagocytic syndrome (HPS) after hematopoietic stem cell transplantation (HSCT). Between July 2006 and December 2007, all patients who received a HSCT in our institution were included in this study. All the following criteria were needed for the diagnosis of HPS: sustained fever over 7 days; cytopenia (neutropenia and/or thrombocytopenia); presence of more than 3% mature macrophages in bone marrow; hyperferritinaemia (>1,000 ng/mL).

[Identification of SHV-type extended spectrum beta-lactamase genes in Pseudomonas aeruginosa by PCR-restriction fragment length polymorphism and insertion site restriction-PCR].

We propose a simple and rapid method to discriminate SHV-type extended spectrum beta-lactamase (ESBL) genes in P. aeruginosa based on PCR techniques (PCR-RFLP and RSI-PCR). We studied 22 producing ESBL P.

Allogeneic hematopoietic stem cell transplantation in Tunisia.

In 1998, the Tunisian team of the 'Centre National de Greffe de Moelle Osseuse' initiated allogeneic hematopoietic SCT (AHSCT) in Tunisia. As of June 2007, information was collected about 299 patients with a first AHSCT and 12 additional retransplants. The median age was 19 years (range 2-49 years).
