Abstract: A catheter includes proximal and distal sections, a shaft coupled between the proximal and distal sections, and optical fibers extending through the shaft and to the distal section of the catheter. The distal section includes a support structure that includes a proximal end, a distal end, reflective elements, and a cap disposed over a portion of the distal end of the support structure. The proximal end includes alignment receptacles. Each of the optical fibers is inserted into corresponding ones of the alignment receptacles and the alignment receptacles are shaped to maintain the optical fibers straight in the support structure. The distal end includes orifices facing different directions. Each of the optical fibers is optically aligned with corresponding ones of the lenses, reflective elements, and orifices such that the optical fibers in the support structure are straight. The cap includes optical ports aligned with the orifices.

Abstract: The present invention relates to the treatment of T-cell acute lymphoblastic leukemia (T-ALLs) by means of immunotherapy with a monoclonal antibody which recognizes the pre-TCR receptor which, due to its presence in all phases of T-ALL pre-TCR+ development, can also be used as a leukemia-initiating cell (LIC) biomarker and as a therapeutic target useful for monitoring minimal residual disease and identifying compounds inhibiting the disease.

Abstract: A switch, in particular a grounding switch, is for quickly establishing a ground connection and for extinguishing an arc fault for a switching system. The grounding switch includes at least one fixed contact having a first cable feed, a moving contact, a contact guide having a second cable feed, and a mechanical energy store. In the opened state, an insulating distance between the fixed contact and the moving contact, is filled with insulation liquid, at least in part. The switch further includes a triggering device and a locking mechanism.
