Persistent SARS-CoV-2 infection resolved after B-cell recovery in a patient with follicular lymphoma treated with B-cell depletion therapy.

A 68-year-old woman with follicular lymphoma was treated with chemotherapy, including the anti-CD20 monoclonal antibody obinutuzumab, and achieved remission. A month after the administration of obinutuzumab, the patient contracted coronavirus disease 2019 (COVID-19), and various antiviral drugs were administered. However, the infection had not been eliminated.

Information provision and retrieval by registered salespersons from consumers during over-the-counter drug sales - a questionnaire survey.

Background: In Japan, non-pharmacists who are accredited as registered salespersons can sell over-the-counter (OTC) drugs, and they play a very important role in supporting proper OTC drug use by consumers. The purpose of this study was to evaluate information provided to and information collected from consumers, and cooperation with pharmacists during OTC drug sales by registered salespersons, and to clarify their related concerns and behaviors.

Methods: A cross-sectional questionnaire-based survey of 385 registered salespersons working at 56 drugstores throughout Japan was conducted.

PCR-based INDEL markers co-dominant between Oryza sativa, japonica cultivars and closely-related wild Oryza species.

Wild relatives genetically close to cultivars are precious genetic resources for plant breeding. Oryza rufipogon, O. barthii, O.

Knock-in mouse model of dilated cardiomyopathy caused by troponin mutation.

We created knock-in mice in which a deletion of 3 base pairs coding for K210 in cardiac troponin (cTn)T found in familial dilated cardiomyopathy patients was introduced into endogenous genes. Membrane-permeabilized cardiac muscle fibers from mutant mice showed significantly lower Ca(2+) sensitivity in force generation than those from wild-type mice. Peak amplitude of Ca(2+) transient in cardiomyocytes was increased in mutant mice, and maximum isometric force produced by intact cardiac muscle fibers of mutant mice was not significantly different from that of wild-type mice, suggesting that Ca(2+) transient was augmented to compensate for decreased myofilament Ca(2+) sensitivity.
