Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years.

Atherosclerosis (AS) is a chronic vascular disease characterized by inflammation of the arterial wall and the formation of cholesterol plaques. Hashimoto's thyroiditis (HT) is an autoimmune disorder marked by chronic inflammation and destruction of thyroid tissue. Although previous studies have identified common risk factors between AS and HT, the specific etiology and pathogenic mechanisms underlying these associations remain unclear.

Osteoporosis is caused by an imbalance between bone resorption and formation, which decreases bone mass and strength and increases the risk of fracture. Therefore, osteoporosis is treated with oral resorption inhibitors, such as bisphosphonates, and parenteral osteogenic drugs, including parathyroid hormone and antisclerostin antibodies. However, orally active osteogenic drugs have not yet been developed.

All-solid-state fluoride-ion batteries (FIBs) have attracted extensive attention as candidates for next-generation energy storage devices; however, promising cathodes with high energy density are still lacking. In this study, CuN is investigated as a cathode material for all-solid-state fluoride-ion batteries, which offers enough anionic vacancies around the 2-fold coordinated Cu center for F intercalation, thereby enabling a multielectron-transferred fluorination process. The contribution of both cationic and anionic redox to charge compensation, in particular, the generation of molecular nitrogen species in highly charged states, has been proved by several synchrotron-radiation-based spectroscopic technologies.

A Bioabsorbable Implant Seeded with Adipose-Derived Stem Cells for Adipose Regeneration.

Tissue Eng Part A

January 2025

Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Kyoto University, Kyoto, Japan.

Adipose tissue engineering requires effective strategies for regenerating adipose tissue, with adipose-derived stem cells (ASCs) being favored due to their robust self-renewal capacity and multipotent differentiation potential. In this study, the efficacy of poly-L-lactic acid (PLLA) mesh containing collagen sponge (CS), seeded with ASCs to promote adipose tissue formation, was investigated. PLLA-CS implants seeded with GFP-positive ASCs were inserted at high concentration (1 × 10 cells/implant, H-ASC) and low concentration (1 × 10 cells/implant, L-ASC), as were unseeded controls.

Dynamic change of polarity in spread through air spaces of pulmonary malignancies.

J Pathol

January 2025

Department of Clinical Bio-resource Research and Development, Graduate School of Medicine, Kyoto University, Kyoto, Japan.

Spread through air spaces (STAS) is a histological finding of lung tumours where tumour cells exist within the air space of the lung parenchyma beyond the margin of the main tumour. Although STAS is an important prognostic factor, the pathobiology of STAS remains unclear. Here, we investigated the mechanism of STAS by analysing the relationship between STAS and polarity switching in vivo and in vitro.

Obesity is a global health concern that promotes chronic low-grade inflammation, leading to insulin resistance, a key factor in many metabolic diseases. Angiotensin 1-7 (Ang 1-7), a component of the renin-angiotensin system (RAS), exhibits anti-inflammatory effects in obesity and related disorders, though its mechanisms remain unclear. In this study, we examined the effect of Ang 1-7 on inflammation of white adipose tissue (WAT) in dietary-induced obese mice.

Biophys Physicobiol

September 2024

Molecular and Cellular Biochemistry, Graduate School of Pharmaceutical Sciences, Tohoku University, Sendai, Miyagi 980-8578, Japan.

Single-molecule imaging provides information on diffusion dynamics, oligomerization, and protein-protein interactions in living cells. To simultaneously monitor different types of proteins at the single-molecule level, orthogonal fluorescent labeling methods with different photostable dyes are required. G-protein-coupled receptors (GPCRs), a major class of drug targets, are prototypical membrane receptors that have been studied using single-molecule imaging techniques.
