Article Synopsis
  • Scientists found that malaria parasites, like Plasmodium falciparum, make red blood cells stiff so they can be removed by the spleen.
  • * They tested over 13,000 compounds and found 82 that could help stop malaria from spreading.
  • * Two drugs, NITD609 and TD-6450, were shown to be safe and effective in lab tests, and they might soon be tested in people.

Background: Recent studies report very low adherence of practitioners to ATS/IDSA recommendations for the treatment of nontuberculous mycobacteria pulmonary disease (NTM-PD), as well as a great variability of practices. Type of management could impact prognosis.

Methods: To evaluate management and prognosis of patients with NTM-PD cases with respect to ATS recommendations, we conducted a multicenter retrospective cohort study (18 sentinel sites distributed throughout France), over a period of six years.

Haspin is a mitotic protein kinase required for proper cell division by modulating Aurora B kinase localisation and activity as well as histone phosphorylation. Here a series of imidazopyridazines based on the CHR-6494 and Structure Activity Relationship was established. An assessment of the inhibitory activity of the lead structures on human Haspin and several other protein kinases is presented.

The mechanical retention of rigid erythrocytes in the spleen is central in major hematological diseases such as hereditary spherocytosis, sickle-cell disease and malaria. Here, we describe the use of microsphiltration (microsphere filtration) to assess erythrocyte deformability in hundreds to thousands of samples in parallel, by filtering them through microsphere layers in 384-well plates adapted for the discovery of compounds that stiffen Plasmodium falciparum gametocytes, with the aim of interrupting malaria transmission. Compound-exposed gametocytes are loaded into microsphiltration plates, filtered and then transferred to imaging plates for analysis.

Background: Storage lesion may explain the rapid clearance of up to 25% of transfused red blood cells (RBCs) in recipients. Several alterations affect stored RBC but a quantitative, whole cell-based predictor of transfusion yield is lacking. Because RBCs with reduced surface area are retained by the spleen, we quantified changes in RBC dimensions during storage.
