Inter- and Intrasublattice Spin Mixing Conductance of the Antiferromagnetic Spin Pumping Effect in α-Fe_{2}O_{3}/Pt.

The spin pumping effect in antiferromagnets, which ultimately converts THz waves into a spin current, is the key physical mechanism leading to an essential function which harnesses the THz technology and spintronics. Here, we report thorough experimental investigations of the spin current induced by the antiferromagnetic spin pumping effect in epitaxial α-Fe_{2}O_{3} thin films having two distinct dynamic modes and unambiguously show that both the inter- and intrasublattice spin mixing conductance are equally substantial. Our experimental insight is an important advance for understanding the physics of transduction between the spin current and the staggered magnetization dynamics at THz frequency.

Time from drainage to surgery is an independent predictor of morbidity for moderate-to-severe acute cholecystitis: a multivarirble analysis of 259 patients.

Background: Acute cholecystitis (AC) is an acute inflammatory disease of the gallbladder and one of the most frequent causes of acute abdominal pain. Early cholecystectomy is recommended for mild cholecystitis. However, the optimal surgical timing for moderate-to-severe cholecystitis requiring percutaneous transhepatic gallbladder drainage (PTGBD) remains unclear.

Tazobactam/Ceftolozane (TAZ/CTLZ) and Relebactam/Imipenem (REL/IPM) susceptibility in Japan: nationwide surveillance of respiratory bacterial pathogens in 2019/20.

Tazobactam/ceftolozane (TAZ/CTLZ) and relebactam/imipenem/cilastatin (REL/IPM/CS) are expected to be effective for treating patients with antimicrobial-resistant infections, particularly gram-negative pathogens, but nationwide surveillance of these has not been investigated thoroughly in Japan. Pseudomonas aeruginosa (n=164), Klebsiella pneumoniae (n=141), and Haemophilus influenzae (n=156) isolated from respiratory infected patients in Japan from June 2019 through December 2020 provided by the Japanese Surveillance Committee were used. Antimicrobial susceptibility testing for TAZ/CTLZ, REL/IPM and comparator agents against isolates were carried out by broth microdilution methods according to the Clinical and Laboratory Standards Institute standard.

Curative Surgery After Neoadjuvant Chemotherapy for Locally Advanced Sigmoid Colon Cancer With Extensive Abdominal Wall Invasion: A Case Report.

Locally advanced colon cancer (LACC) can be cured under an appropriate treatment strategy, but the decision on the treatment strategy is also important in terms of long-term prognosis. In cases with extensive abdominal wall involvement, it is especially important to secure adequate margins and repair abdominal wall defects. Recently, neoadjuvant chemotherapy (NAC) for LACC has shown promise in improving the chance of cure with tumor shrinkage.
