Article Synopsis
- Iron-based 1111-type superconductors are known for their high critical temperatures and current densities, but traditional methods to increase current density (J) are limited.
- Researchers improved J in SmFeAsOH films by increasing carrier density via high electron doping, which significantly reduced penetration depth and coherence length.
- This innovative approach led to a remarkable increase in J to 415 MA/cm, comparable to cuprate superconductors, and demonstrated successful application across other iron-based superconductors as well.
Article Synopsis
- - A 63-year-old man with adult T-cell leukemia-lymphoma received a bone marrow transplant from an unrelated donor and was later diagnosed with invasive pulmonary aspergillosis (IPA) 17 days post-transplant.
- - He initially improved with treatment using liposomal amphotericin B, but was switched to voriconazole due to worsening kidney function, and later experienced neurological issues.
- - The patient passed away on day 62, with an autopsy revealing fungal infection in the lungs and a ruptured cerebral aneurysm, emphasizing the need for careful monitoring of transplant patients for fungal-related complications.
Introduction: In the context of double-valve surgery for elderly high-risk patients involving both the aortic and mitral valves, a clinically significant problem has been that no clear criteria or surgical strategies have been reported for the selection of mitral valve plasty (MVP) or mitral valve replacement (MVR) for mitral valve disease management during surgical aortic valve replacement (SAVR) to achieve better clinical outcomes. This study investigated valve durability and survival using our surgical strategy for mitral valve disease with concomitant SAVR in elderly patients.
Methods: Eighty-six patients aged > 65 years (mean 75 years) who underwent a double-valve procedure for mitral valve surgery with concomitant SAVR from 2010 to 2022 were reviewed.
There is no clear consensus regarding the optimal isolation duration for immunocompromised patients with coronavirus disease 2019 (COVID-19). Therefore, we conducted a questionnaire survey at eight Japanese cancer centers to investigate the practices of infectious disease specialists regarding the duration of isolation for COVID-19 inpatients with cancer. For asymptomatic to severely ill COVID-19 inpatients without severe immunodeficiency, four centers reported at least 10 days of isolation without testing, and two reported at least 20 days.

In Japan, Koshihikari is the most popular rice variety, and it has been widely cultivated for many years despite its susceptibility to lodging. Reducing basal fertilizer is recommended when the available nitrogen in soil (SAN) exceeds the optimum level (80-200 mg N kg).
