Efficacy of platelet gel in reconstructive bone surgery.

Autologous platelet concentrate and cryoprecipitate, mixed to obtain a gel, have been successful in various operations, primarily oral and maxillofacial surgery. This study assessed the use of platelet gel in 19 patients undergoing 22 reconstructive bone surgical procedures. After a median follow-up of 12.

A whole genome screen for linkage disequilibrium in multiple sclerosis performed in a continental Italian population.

We have systematically screened the genome for evidence of linkage disequilibrium (LD) with multiple sclerosis (MS) by typing 6000 microsatellite markers in case-control and family based (AFBAC) cohorts from the Italian population. DNA pooling was used to reduce the genotyping effort involved. Four DNA pools were considered: cases (224 Italian MS patients), controls (231 healthy Italians), index (185 index cases from trio families) and parents (the 370 parents of the patient included in the Index pool), respectively.

Prolactin and prolactin receptor gene polymorphisms in multiple sclerosis and systemic lupus erythematosus.

Genes encoding for prolactin (PRL) and its receptor (PRLR) are possible candidates for multiple sclerosis (MS) and systemic lupus erythematosus (SLE) susceptibility. In fact: (1) a prolactin secretion dysfunction has been described in several autoimmune diseases including SLE and MS and their animal models; (2) both PRL and PRLR are structurally related to members of the cytokine/hematopoietin family and have a role in the regulation of the immune response; and (3) both PRL and PRLR genes map in genomic regions that showed linkage with autoimmunity. Prolactin maps on chromosome 6p, about 11-kb telomeric to HLA-DRB1 and PRLR in 5p12-13, which revealed evidence of linkage with MS in different populations.
