Amine reclaiming technologies in post-combustion carbon dioxide capture.

Amine scrubbing is the most developed technology for carbon dioxide (CO2) capture. Degradation of amine solvents due to the presence of high levels of oxygen and other impurities in flue gas causes increasing costs and deterioration in long term performance, and therefore purification of the solvents is needed to overcome these problems. This review presents the reclaiming of amine solvents used for post combustion CO2 capture (PCC).

The outcome of autologous stem cell transplantation in patients with plasma cell disorders and dialysis-dependent renal failure.

Patients with multiple myeloma and end-stage renal failure on dialysis are frequently not considered eligible for high-dose therapy (HDT) due to higher transplant-related mortality (TRM). Our aim was to evaluate the toxicity and survival of dialysis-dependent patients after HDT with melphalan (100 mg/m(2)) compared to those of patients without renal insufficiency (melphalan 200 mg/m(2)) in a matched pairs analysis of 34 patients. No significant differences were observed between hematologic toxicity, TRM or disease response.

Effect of CD34 cell dose on hematopoietic reconstitution and outcome in 508 patients with multiple myeloma undergoing autologous peripheral blood stem cell transplantation.

Background: We analyzed the hematopoietic reconstitution and outcome of 508 patients with multiple myeloma (MM) with respect to the number of CD34+ cells reinfused at our center.

Patients And Methods: Each cohort of 390 patients (unselected CD34+ cell transplant) and 118 patients (CD34+ selected transplant) was divided into four subgroups. Among the 390 transplantations, 86 patients received a high dose (HD-) of > or =6.
