Geobacter sulfurreducens strain 60473, a potent bioaugmentation agent for improving the performances of bioelectrochemical systems.

Bioaugmentation with electrochemically active bacteria (EAB) has been suggested useful for improving the performance of bioelectrochemical systems (BESs) for sustainable energy generation, while its success is dependent on EAB introduced into the systems. Here we report on the isolation of a novel EAB, Geobacter sulfurreducens strain 60473, from microbes that colonized on an anode of a sediment microbial fuel cell. This strain is highly adhesive to graphite electrodes, forms dense biofilms on electrode surfaces, and generates high current densities in BESs.

Transmission of Severe Fever with Thrombocytopenia Syndrome Virus to Human from Nonindigenous Tick Host, Japan.

We report a human case of severe fever with thrombocytopenia syndrome virus infection transmitted by a tick, confirmed by viral identification. Haemaphysalis aborensis, a tick species not native to Japan that has been observed to transmit the virus to humans, is now recognized as a potential vector of this virus in Japan.

Naphthalen-1-ylethanamine-containing small molecule inhibitors of the papain-like protease of SARS-CoV-2.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has not yet been eradicated. SARS-CoV-2 has two types of proteases, a main protease (M) and a papain-like protease (PL), which together process two translated non-structural polyproteins, pp1a and pp1ab, to produce functional viral proteins. In this study, effective inhibitors against PL of SARS-CoV-2 were designed and synthesized using GRL-0048 as a lead.

[Minimally Invasive Aortic Valve Replacement for Aortic Valve Infective Endocarditis Complicated by Septic Arthritis of the Sternoclavicular Joint:Report of a Case].

A 54-year-old man with a history of atopic dermatitis was admitted to our hospital for persistent fever and multiple arthralgias unresponsive to antibiotics. On the second day of hospitalization, Staphylococcus aureus was detected in the blood culture, and debridement for presumed pyogenic arthritis was performed on the patient's bilateral wrists and right ankle joints. Echocardiography showed evidence of infective endocarditis of the aortic valve.

Performance of Fujifilm Dengue NS1 Antigen Rapid Diagnosis Kit Compared to Quantitative Real-Time Polymerase Chain Reaction.

Dengue is a viral infection caused by the dengue virus (DENV), transmitted to humans through the bite of infected mosquitoes. About half of the world's population is now at risk of dengue, which represents a global public health concern, especially in tropical and subtropical countries. Early detection of the viral infection is crucial to manage the disease; hence, effective rapid diagnostic tests are essential.
