Ischemic heart disease is the main global cause of death in the world. Abnormal sulfide catabolism, especially hydrogen sulfide accumulation, impedes mitochondrial respiration and worsens the prognosis after ischemic insults, but the substantial therapeutic strategy has not been established. Non-thermal atmospheric pressure plasma irradiation therapy is attracted attention as it exerts beneficial effects by producing various reactive molecular species.

Article Synopsis
  • * Using mouse models, researchers found that renal injury activated the mineralocorticoid receptor (MR), which was linked to increased levels of HMGB1 and RAGE, and that blocking this pathway lessened kidney damage and inflammation.
  • * Results indicate that HMGB1 is a key factor in the development of AKI and its progression to CKD by activating the Rac1/MR pathway, suggesting potential therapeutic targets for preventing kidney injury.

Decreasing electricity costs of clean room for cell products during non-operation.

Regen Ther

June 2024

Center for Stem Cell and Regenerative Medicine, Institute of Science Tokyo, 1-5-45, Bunkyo-ku, Yushima, Tokyo 113-8519, Japan.

Introduction: Cell processing facilities are susceptible to environmental bacteria and must maintain sterile environments to safeguard cell products. This process involves circulating air through high-efficiency particulate air (HEPA) filters, which incurs significant maintenance costs. While cost-reduction strategies have been explored in the semiconductor industry, validations specific to cell processing facilities remain unreported.

Spinodal Decomposition by a Two-Step Procedure for Nano Porous Silica.

ACS Phys Chem Au

November 2024

Nanomatereials Development Dept. 11, Nanomaterials R&D Center, R&D Headquarters, Canon Inc., 30-2, Shimomaruko 3-chome, Ohta-ku, Tokyo 146-8501, Japan.

The phase separation of the NaO-BO-SiO system was explored both theoretically and experimentally in order to attain a spinodal structure having a narrowed periodic distance (<70 nm) with the porosity being kept at ∼60%. The phase separation was dealt with by two stages: an initial thermodynamic process of spinodal decomposition and a latter growth of the spinodal structure. The initial structural development was related to the interfacial energy and the change in free energy caused by phase separation.

Tissue clearing, coupled with immunostaining, enables the transition from two-dimensional to three-dimensional pathology and has the potential to substantially improve data quality for biomedical diagnostics. Nevertheless, the workflows are limited by the complex sample processing protocols. Approaches for the parallel processing of samples, to include tissue clearing, immunostaining, imaging and analysis can increase three-dimensional pathology throughput.

Leveraging the features of the GstLAL pipeline, we present the results of a matched filtering search for asymmetric binary black hole systems with heavily misaligned spins in LIGO and Virgo data taken during the third observing run. Our target systems show strong imprints of precession whereas current searches have nonoptimal sensitivity in detecting them. After measuring the sensitivity improvement brought by our search over standard spin-aligned searches, we report the detection of 30 gravitational wave events already discovered in the latest version of the Gravitational Wave Transient Catalog.

Orofacial morphology in mammals plays a critical role in essential life functions such as feeding and communication, which are influenced by the shapes of these anatomical structures. Bats are known to exhibit highly diversified orofacial morphotypes within their clade, reflecting their varied diets and echolocation behaviors. The presence of bony discontinuities between the premaxilla and maxilla or among the premaxillae is a notable feature of bat orofacial morphology, observed in certain lineages.
