Purpose: The purpose of this study was to describe the characteristics of pediatric patients who underwent nonoperative management (NOM) for blunt splenic and hepatic injuries and to explore factors associated with NOM failure.
Methods: This was a secondary analysis of a multicenter cohort study of pediatric patients with blunt liver and spleen injuries in Japan. Participants included pediatric trauma patients aged 16 years or younger between 2008 and 2019 with NOM, which was defined as no surgery provided within 6 h of hospital arrival.
-[Ru(EtOtpy)(pynp)Cl] (-) (EtOtpy = 4'-ethoxy-2,2':6',2″-terpyridine, pynp = 2-(2-pyridyl)-1,8-naphthyridine), and /-[Ru(EtOtpy)(pynp)OH] (/-) complexes were newly synthesized to investigate the synergistic influence of the geometric configuration coupled with substituent introduction of an ethoxy (EtO) group on the physicochemical properties and reactions of the Ru(II) complexes. Configurationally nonselective aquation of - was uniquely observed to form /- isomers in water, in contrast to configurationally selective aquation of -[Ru(tpy)(pynp)Cl] (-, tpy = 2,2':6',2″-terpyridine) without the EtO group [Yamazaki, H. .

Administering a restricted amount of oxygen in the early phase after ROSC has been suggested as a potential therapy for PCAS; however, the optimal target for arterial partial pressure of oxygen or peripheral oxygen saturation (SpO) to safely and effectively reduce oxygen remains unclear. Therefore, we aimed to validate the efficacy of restricted oxygen treatment with 94%-95% of the target SpO during the initial 12 hours after ROSC for patients with PCAS.

The precursor preparation at 20 °C followed by calcination at 550 °C produced NW-WO nanocrystals ( <100 nm width, 3-5 μm length) with anisotropic growth of monoclinic WO crystals to (002) and (200) planes and a polycrystalline character with randomly oriented crystallites in the lateral face of nanowires. The precursor preparation at 45 °C followed by calcination at 550 °C produced HP-WO nanocrystals ( 500-1000 nm diameter) with preferentially exposed (002) and (020) facets on the top-flat and side-rectangle surfaces, respectively, of hexagonal prismatic WO nanocrystals with a single-crystalline character.

We speculated that efficacy resulted from the amelioration of epidermal ceramide metabolism, and we characterized those effects using reconstructed human epidermal equivalents. Lipid analysis, RT-PCR and Western blotting revealed that HC significantly increased the total ceramide content of the stratum corneum (SC), accompanied by significantly increased gene and/or protein expression levels of ceramide synthase (CERS) 3, fatty acid elongase (ELOVL) 4, glucosylceramide synthase (GCS), β-glucocerebrosidase, sphingomyelin synthase and acid sphingomyelinase.

The production of biofilm protects resident bacteria from host immune defenses and antibiotic interventions, prolonging pathogen survival, and risking recurrence after treatment. Glycated proteins formed from keratin and glucose induce biofilm formation in , promoting dysbiosis and increasing pathogenicity.

Previous randomized controlled trials suggested that uniformly adopting a target mean arterial pressure (MAP) higher than 65 mmHg for all adult septic shock patients would not be beneficial; however, it has also been proposed that higher target MAP may be beneficial for elderly patients, especially those with arteriosclerosis.

The ultraviolet (UV)-visible absorption spectra of /- isomers show intense bands for metal-to-ligand charge transfer (MLCT) at close wavelengths of 576 and 573 nm, respectively. However, time-dependent density functional theory (TD-DFT) calculations suggest that the MLCT transition of - involves mainly single transitions to the π* orbital of the dpda ligand in contrast to mixing of the π* orbitals of the dpda and tpy ligands for -.

Background: Some academic organizations recommended that physicians intubate patients with COVID-19 with a relatively lower threshold of oxygen usage particularly in the early phase of pandemic. We aimed to elucidate whether early intubation is associated with decreased in-hospital mortality among patients with novel coronavirus disease 2019 (COVID-19) who required intubation.
Methods: A multicenter, retrospective, observational study was conducted at 66 hospitals in Japan where patients with moderate-to-severe COVID-19 were treated between January and September 2020.

The chemical oxidation of the Ru(OH)(OH) core with the vicinal OH and OH ligands was spectroscopically and theoretically investigated to provide a mechanistic insight into the O-O bond formation in the core. We demonstrate O-O bond formation at the low-valent Ru(OH) core with the vicinal OH ligands to form the Ru(μ-OOH) core with a μ-OOH bridge.

Vagus nerve stimulation (VNS) administered to individuals following events such as severe trauma can be a potential therapy to attenuate gut injury and its sequelae. To determine the effective dose of transcutaneous electrical VNS (TE-VNS) and explore an effective method for performing TE-VNS, a measurement system was developed for the detection of vagus nerve response to TE-VNS. In addition, a noise-suppressed transcutaneous electrical stimulator (TES) was constructed for the same purpose.

A ruthenium complex showing multi-stimuli-responsive isomerization was synthesized. The catalytic activity of this complex toward water oxidation showed responses to visible-light irradiation and heat due to photoisomerization and thermal back-isomerization, respectively. DFT calculations suggested that a pendant moiety in the complex was key to controlling the catalytic activity.
