Design of soft x-ray high diffraction efficiency and spectral flux Au/Ni bilayer coated laminar-type diffraction grating for objective soft x-ray flat-field spectrograph in a region of 250-550 eV.

An objective soft x-ray flat-field spectrograph employing a laminar-type bilayer coated, varied-line-spacing, spherical grating was designed to improve the detection limit and sensitivity of soft x-ray flat-field spectrographs in a region of 250-550 eV. As a design criterion, spectral flux, SF, [Hatano et al., Appl.

Relationship between skeletal muscle mass change and swallowing function improvement among stroke patients with dysphagia during rehabilitation.

Objectives: The purpose of this study was to evaluate the relationship between changes in skeletal muscle mass and improvements in swallowing function in stroke patients with dysphagia during rehabilitation.

Methods: The study included 145 patients with a stroke or dysphagia. The two groups were divided into two groups: those with improved skeletal muscle mass index (SMI) at discharge and those without.

Clinical characteristics in adolescents and young adults with polycythemia vera and essential thrombocythemia in Japan.

We report the first large-scale retrospective cohort study on adolescent and young adult (AYA) polycythemia vera (PV) and essential thrombocythemia (ET) in Japan, a subgroup analysis using Japanese multicenter registry data (JSH-MPN-R18). This study included patients with PV (n = 31) or ET (n = 141) aged 20 to 39 years at the initial visit. Hemorrhage-free survival (HFS) was better in AYA ET than in non-AYA ET (5-year HFS: 100% vs.

Bortezomib Led to Remission of Immune Thrombocytopenic Purpura in a Patient with Smoldering Multiple Myeloma.

A 79-year-old man with smoldering multiple myeloma (MM) developed sudden severe thrombocytopenia and active bleeding. Since anti-GPIIb/IIIa autoantibodies were detected on the platelet surface, thrombocytopenia due to an autoimmune etiology was diagnosed. Although neither steroids nor intravenous immunoglobulins provided improvement, bortezomib provided rapid normalization of the platelet counts with disappearance of the anti-GPIIb/IIIb autoantibodies.
