Diffusion-driven transient hydrogenation in metal superhydrides at extreme conditions.

In recent years, metal hydride research has become one of the driving forces of the high-pressure community, as it is believed to hold the key to superconductivity close to ambient temperature. While numerous novel metal hydride compounds have been reported and extensively investigated for their superconducting properties, little attention has been focused on the atomic and electronic states of hydrogen, the main ingredient in these novel compounds. Here, we present combined H- and La-NMR data on lanthanum superhydrides, LaH, (x = 10.

Topological importance of CD8 T-cell enrichment in the tumor microenvironment of classic Hodgkin lymphoma.

Classic Hodgkin lymphoma (CHL) histologically consists of Hodgkin Reed-Sternberg (HRS) cells and the tumor microenvironment (TME), but the relationship between TME characteristics and clinical features of CHL remains unclear. We aimed to investigate the effects of the TME structure on the outcomes of patients with CHL. We performed a high-throughput analysis of HRS cells and their topological relationship with the reactive immune cells in the TME.

Elevated hematopoietic stem cell frequency in mouse alveolar bone marrow.

Hematopoietic stem cells (HSCs) are crucial for maintaining hematopoietic homeostasis and are localized within distinct bone marrow (BM) niches. While BM niches are often considered similar across different skeletal sites, we discovered that the alveolar BM (al-BM) in the mandible harbors the highest frequency of immunophenotypic HSCs in nine different skeletal sites. Transplantation assays revealed significantly increased engraftment from al-BM compared to femur, tibia, or pelvis BM, likely due to a higher proportion of alveolar HSCs.

Romosozumab versus bisphosphonates for preventing subsequent vertebral fractures after balloon kyphoplasty: comparison using data from two prospective multicenter studies.

Preventing subsequent fractures after vertebral augmentation is a critical clinical concern. The purpose of this study was to compare the effect of romosozumab and bisphosphonate administration on the occurrence of subsequent vertebral fractures after balloon kyphoplasty (BKP) and to identify factors associated with the occurrence of subsequent vertebral fractures. The study compared 24 patients who underwent BKP and received romosozumab with 58 control patients who underwent BKP and received bisphosphonates, all within 2 months of acute osteoporotic vertebral fracture and showing unfavorable magnetic resonance imaging prognostic factors.

Identification of a pancreatic juice-specific fluorescent probe through 411 probes activated by aminopeptidases/proteases or phosphatases/phosphodiesterases.

Background: This study is a retrospective review aimed to identify pancreatic juice-specific fluorescent probes to visualize pancreatic juice using a library of 381 aminopeptidase/protease-activatable fluorescent probes and 30 phosphatase/phosphodiesterase probes. In 2013, we developed a fluorescence imaging technique using a chymotrypsin probe to visualize pancreatic juice, linked to postoperative pancreatic fistula (POPF). This probe required addition of trypsin to convert pancreatic chymotrypsinogen to chymotrypsin.

Background: Previous injury and physical examination data collected by a physiotherapist were reviewed to investigate the causes of injury among competitive swimmers. Each swimmer received an injury improvement exercise program based on their injury history and physical examination findings.

Purpose: The purpose of this study was to identify trends in the number of shoulder and lumbar injuries and discern the effectiveness of exercise programs in swimmers.

Definitive Evidence for the Identification and Function of Renin-Expressing Cholinergic Neurons in the Nucleus Ambiguus.

Background: The importance of the brain renin-angiotensin system in cardiovascular function is well accepted. However, not knowing the precise source of renin in the brain has been a limitation toward a complete understanding of how the brain renin-angiotensin system operates.

Methods: Highly sensitive in situ hybridization techniques and conditional knockout mice were used to address the location and function of renin in the brainstem.

The Effect of Bone Mechanical Stress Caused by Electrical Stimulation-Induced Muscle Contraction on Osteocalcin Secretion.

Electrical stimulation-induced muscle contraction (ESMC) has demonstrated various physiological benefits, but its effects on the secretion of undercarboxylated osteocalcin (ucOC), a bone-derived cytokine, remain unclear. This study explored the relationship between ESMC, bone strain, and ucOC secretion through two experiments. In the first, young male Fischer 344 rats were divided into three groups: low-frequency ES (LF, 10 Hz), high-frequency ES (HF, 100 Hz), and control (CON).

Characteristics of hospital pediatricians and obstetricians/gynecologists working long hours in Tokushima, Japan: A cross-sectional study.

Background: This study aimed to determine the actual working conditions, including working hours and desired future working styles of hospital pediatricians and obstetricians/gynecologists (OB/GYNs) in Tokushima Prefecture.

Method: This cross-sectional study used a self-administered questionnaire. Pediatricians and OB/GYNs (n = 96) working at 14 hospitals in Tokushima Prefecture were surveyed.

Development of α-ray visualization survey meter in high gamma and neutron background environment.

A survey meter was developed to reliably detect and visualize surface contamination of suits and objects by α-nuclides in high γ/n-rays background radiation environment. The survey meter features a semi-opaque ZnS:Ag scintillator mounted directly onto a multi-anode photomultiplier tube (MA-PMT) and amplification circuits, ensuring output gain equalization for all channels. α-ray events induce localized light emission in thin-film scintillators.

Comparison of forced and voluntary exercise types on male rat brain monoamine levels, anxiety-like behaviour, and physiological indexes under light and dark phases.

Purpose: Physical exercise improves physical and mental health; however, the differences between voluntary and forced exercise protocols are unclear. In addition, knowledge regarding the consequences of differences in testing timing, such as light and dark phases, in response to exercise type is limited. We investigated the effects of chronic forced and voluntary wheel running on the changes in brain monoamine levels (5-HT: serotonin, DA: dopamine, NA: noradrenaline), anxiety-like behaviours, and physiological stress responses in the light and dark phases.

Denoising cosine similarity: A theory-driven approach for efficient representation learning.

Representation learning has been increasing its impact on the research and practice of machine learning, since it enables to learn representations that can apply to various downstream tasks efficiently. However, recent works pay little attention to the fact that real-world datasets used during the stage of representation learning are commonly contaminated by noise, which can degrade the quality of learned representations. This paper tackles the problem to learn robust representations against noise in a raw dataset.

Radical Scavenging Capacity and In Vitro Cytoprotective Effects of Great Salt Lake-Derived Processed Mineral Water.

The Great Salt Lake, located in Utah, USA, is a saltwater lake with no outlet and is surrounded by vast mountains and salt deserts. We aimed to use Great Salt Lake-derived processed mineral water (hereafter termed as GSL-MW) for maintaining oral health. Therefore, we examined its radical scavenging activity as an antioxidant and its cytoprotective effect on human gingival fibroblasts (hGFs).

Streptomyces yaizuensis sp. nov., a berninamycin C-producing actinomycete isolated from sponge.

While screening for antibiotics in a marine sample, we discovered a berninamycin C-producing actinomycete, designated YSPA8, isolated from a sponge. A polyphasic approach was used to determine the taxonomic position of the strain. Strain YSPA8 formed sympodially branched aerial mycelia that ultimately segment into chains of spores.

A large-scale in silico replication of ecological and evolutionary studies.

Despite the growing concerns about the replicability of ecological and evolutionary studies, no results exist from a field-wide replication project. We conduct a large-scale in silico replication project, leveraging cutting-edge statistical methodologies. Replicability is 30%-40% for studies with marginal statistical significance in the absence of selective reporting, whereas the replicability of studies presenting 'strong' evidence against the null hypothesis H is >70%.

Label-free ghost cytometry for manufacturing of cell therapy products.

Automation and quality control (QC) are critical in manufacturing safe and effective cell and gene therapy products. However, current QC methods, reliant on molecular staining, pose difficulty in in-line testing and can increase manufacturing costs. Here we demonstrate the potential of using label-free ghost cytometry (LF-GC), a machine learning-driven, multidimensional, high-content, and high-throughput flow cytometry approach, in various stages of the cell therapy manufacturing processes.
