Background Over the last two decades,umbilical cord blood(UCB)and haploidentical transplantation(HaploHSCT)have emerged as alternative sources of hematopoietic stem cell for allogeneic *** are few retrospective studies and no prospective studies comparing both types of alternative transplantation in pediatric *** We analyzed the data of 134 children with hematological malignancies who received a hematopoietic stem cell transplantation from a single umbilical cord blood(UCB)(n=42)or an"tex-vivo"T-cell depleted transplant from a haploi-dentical-related donor(HaploHSCT)(n=92)between 1996 and *** recovery was faster after HaploHSCT than the UCB transplant group(median times to neutrophil and platelet recovery:13 vs.16 days,10 vs.57 days,respectively)(P<0.001).The HaploHSCT group had a significantly early immune reconstitution based on NK and CD8+T cells compared with the UCB ***,after the first year *** had a lower number of CD4+ T and B lymphocytes compared with the UCB transplant *** cumulative incidence of TRM was 29±8%in the HaploHSCT group versus 40±5%in the UCB *** incidence was 21±7%in the HaploHSCT group and 19±8%in the UCB *** of DFS was 58±8%in the HaploHSCT group versus 40±9%in the UCB group(P=0.051).Conclusions TCD haploidentical transplant is associated with advantages in terms of engraftment and early immune reconstitution *** haploidentical transplant was associated with lower incidence of infectious and non-infectious complications,especially in the early phases of the transplant compared with UCB transplant ***,there are no advantages in transplant outcomes compared with UCB transplant.

Novel antibacterial materials for implants and medical instruments are essential to develop practical strategies to stop the spread of healthcare associated infections. This study presents the synthesis of multifunctional antibacterial nanocoatings on polydimethylsiloxane (PDMS) by remote plasma assisted deposition of sublimated chlorhexidine powders at low pressure and room temperature. The obtained materials present effective antibacterial activity against Escherichia coli K12, either by contact killing and antibacterial adhesion or by biocide agents release depending on the synthetic parameters. In addition, these multifunctional coatings allow the endure hydrophilization of the hydrophobic PDMS surface, thereby improving their biocompatibility. Importantly, cell-viability tests conducted on these materials also prove their non-cytotoxicity, opening a way for the integration of this type of functional plasma films in biomedical devices.

Biosurfactants were synthesized by Pseudomonas aeruginosa （P.A.）, using sugar cane molasses as carbon source. Assays were conducted in a shaker with agitation speed of 200 rpm, temperature of 38 ℃ and aeration ratio （Vm/Vf） of 0.4 and 0.6. A concentration of 3.0% was used for the carbon and energy source （molasses） and of 0.3% for the nitrogen source （NaNO3）. Samples were removed at regular times until 96 hours of cultivation. The reduction in surface tension was measured using the ring method; cell concentration was obtained by the dry mass and substrate consumption by the DNS method. The metabolite produced was extracted and quantified by the thioglycolic method. The results showed a maximum surface tension reduction of 46.57% after 60 h, 3.63 g/L of biomass after 8 h （μXmax =0.15 h^-1）, 79.60% of substrate consumption （μs= 0.67 h-1） and 4.47 g/L of rhamnolipid （μp=0.029 h^-1）.
