Mannitol-induced gold nanoparticle aggregation for the ligand-free detection of viral particles.

Traditional virus detection methods require ligands that bind to either viral capsid proteins or viral nucleic acids. Ligands are typically antibodies or oligonucleotides and they are expensive, have limited chemical stability, and can only detect one specific type of virus at a time. Here, the biochemical surface properties of viruses are exploited for ligand-free, nonspecific virus detection.

Olanzapine Reduces Chemotherapy-induced Nausea and Vomiting Compared With Aprepitant in Myeloma Patients Receiving High-dose Melphalan Before Stem Cell Transplantation: A Retrospective Study.

Introduction: Acute and delayed chemotherapy-induced nausea and vomiting (CINV) occurs in most patients who receive high-dose melphalan and significantly affects patients' quality of life during autologous stem cell transplantation. Faced with unsatisfactory results using an aprepitant-based regimen, an olanzapine-based regimen was initiated, with the hope of improving the incidence of acute and delayed CINV. A retrospective study was conducted to compare the effectiveness of olanzapine- versus aprepitant-based regimens for CINV prevention in adult hematopoietic stem cell recipients who received high-dose melphalan.
