While acute pneumonia is commonly observed in the early stages of coronavirus disease 2019 (COVID-19) infection, isolated cases of interstitial pneumonia have been reported several months later. In this case, interstitial lung disease was identified on a routine follow-up examination five months after infection. Eight months after infection, the patient developed worsening interstitial lung disease, pulmonary hypertension, and worsening symptoms, leading to respiratory failure.

In this study, 1,1-difluoroallenes underwent a regioselective [2+3] cycloaddition with nitrile oxides and imine oxides in the presence of a AuCl catalyst. ()-4-Alkylidene-5,5-difluoroisoxazolines and -isoxazolidines were obtained in regioselective and diastereoselective manners by employing aurated difluoroallylic cation intermediates. The synthesized 5,5-difluoroisoxazolines were readily aromatized through dehydrofluorination or allylic fluorine substitution to provide 5-fluoroisoxazoles.

A 78-year-old man with a prostate-specific antigen level of 10 ng/mL was referred to our hospital. Magnetic resonance imaging revealed a Prostate Imaging-Reporting and Data System category of 5 in the apex transition zone. Transrectal and transperineal prostate needle biopsies were performed at a total of 20 sites.

Purpose: MRI-targeted biopsy has improved prostate biopsy yield. However, cost constraints have made it difficult for many institutions to implement the newer methods. We evaluated the performance of a low-cost cognitive-targeting biopsy protocol based on 1.

Alginate is an acidic linear polysaccharide with immune-modulating activities. In this study, we found that enzymatically digested alginate oligomer (AO) with various degrees of polymerization (DP; 2-5) induced a higher level of nitric oxide (NO) production in RAW264.7 cells than undigested alginate polymer (AP).
