6% of the total inhaled dose), and most (41.3%) were deposited in the alveolar region. The total mass of particles deposited was 19.8 ± 16.6 ng/kgbw/g, with 10.1% of the total mass deposited in the alveolar region. Given our findings, the inhalation exposure level is mainly determined by printing conditions, particularly the filament type and manufacturer-recommended extruder temperature.Rituximab (RTX), a chimeric anti-CD20 monoclonal antibody, has demonstrated good efficacy as treatment in patients with resistant chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), but it is highly immunogenic due to its structure. Ocrelizumab (OCR) is a humanized anti-CD20 antibody, with higher tolerability and a lower immunogenic profile compared to RTX. We present a case of refractory CIDP effectively treated with OCR, switched from RTX after the development of anti-drug antibodies. A 25-year-old man was admitted to our clinic for the onset of distal upper and lower limb weakness and numbness, with electrodiagnostic criteria of CIDP. After several attempted standard CIDP treatments, RTX was introduced due to poor control of clinical relapses. Unfortunately, the patient developed a high anti-drug antibody titer after RTX infusion, with no control of disease. OCR was started as an off-label treatment, resulting in partial recovery from the last recurrence and achieving good prevention of new relapses with no adverse events. We suggest that OCR should be considered as another therapeutic option in refractory CIDP. In the literature, this is the first case of CIDP treated with OCR, demonstrating good efficacy for its anti-CD20 effect and better tolerability because of its lower immunogenicity.New materials and chemical knowledge for improved personal protection are among the most pressing needs in the international community. Reported attacks using chemical warfare agents (CWAs,) including organophosphate soman (GD) and thioether mustard gas (HD) are driving research in field-deployable catalytic composites for rapid toxin degradation. In this work, we report simple template-free low temperature synthesis that enables for the first time, a deployable-structured catalytic metal-organic framework/polymer textile composite "MOF-fabric" showing rapid hydrolysis and oxidation of multiple active chemical warfare agents, GD and HD, respectively, and their simulants. Our method yields new zirconium-porphyrin based nano-crystalline PCN-222 MOF-fabrics with adjustable MOF loading and robust mechanical adhesion on low-cost nonwoven polypropylene fibers. Importantly, we describe quantitative kinetic analysis confirming that our MOF-fabrics are as effective as or better than analogous MOF powders for agent degradation, especially for oxidation. Lomeguatrib Faster oxidation using the MOF-fabrics is ascribed to the composite geometry, where active MOF catalysts are uniformly displayed on the MOF-textile enabling better reactant transport and reactive oxidant generation. Furthermore, we note the discovery of visible photo-activation of GD hydrolysis by a MOF-fabric, which is ascribed to oxidation at the active metal node site, significantly increasing the rate over that observed without illumination. These results provide important new insights into the design of future materials and chemical systems to protect military, first-responders, and civilians upon exposure to complex chemical toxins.The Rad50-Mre11 nuclease complex plays a vital role in DNA repair in all domains of life. It recognizes and processes DNA double-strand breaks. Rad50 proteins fold into an extended structure with a 20 to 60 nm long coiled coil connecting a globular ABC ATPase domain with a zinc hook dimerization domain. A published structure of an archaeal Rad50 zinc hook shows coiled coils pointing away from each other. Here we present the crystal structure of an alternate conformation displaying co-aligned coiled coils. Archaeal Rad50 may thus switch between rod-shape
