Absence of damaging effects of stem cell donation in unrelated donors assessed by FISH and gene variance screening.

Granulocyte-Colony-Stimulating factor (G-CSF) is currently the standard mobilising agent for peripheral blood stem cell (PBSC) donation. Concerns that it may trigger chromosome aberrations similar to those observed in leukaemia patients were refuted but long-term effects of G-CSF mobilisation on genome integrity remains unclear. In the setting of a multi-centre clinical trial we screened blood samples from 50 PBSC donors at cellular and gene level for aberrations common in haematological malignancies using fluorescence in situ hybridisation (FISH) and next generation sequencing (NGS) assays.

Blood concentrations of clobazam and norclobazam in a lethal case involving clobazam, meprobamate and clorazepate.

Clobazam is a benzodiazepine with anti-anxiety and anticonvulsant properties marketed in several countries. Norclobazam, a metabolite of clobazam, has similar pharmacological activity but weaker sedative and tranquilizing effect. The two drugs were detected by GC-MS and determined by HPLC-DAD in the samples from a postmortem case.

Report from the killer immunoglobulin-like receptor (KIR) anthropology component of the 15th International Histocompatibility Workshop: worldwide variation in the KIR loci and further evidence for the co-evolution of KIR and HLA.

The killer immunoglobulin-like receptor (KIR) anthropology component of the 15th International Histocompatibility Workshop (IHIWS) sought to explore worldwide population variation in the KIR loci, and to examine the relationship between KIR genes and their human leukocyte antigen (HLA) ligands. Fifteen laboratories submitted KIR genotype and HLA ligand data in 27 populations from six broad ethnic groups. Data were analyzed for correlations between the frequencies of KIR and their known HLA ligands.

Effects of a nebulized NONOate, DPTA/NO, on group B streptococcus-induced pulmonary hypertension in newborn piglets.

NONOates are chemical compounds that are stable as solids but generate nitric oxide (NO) in aqueous solutions. When nebulized or instilled intratracheally, NONOates can attenuate pulmonary hypertension in adult animals with lung injury. To assess the effect of a nebulized NONOate, DPTA/NO, on group B Streptococcus (GBS)-induced pulmonary hypertension in newborn piglets, we studied 20 anesthetized and mechanically ventilated piglets (4-10 d).
