Bone broth has recently gained worldwide recognition as a superfood that supplements several nutrients lacking in modern human diets; however, little is known of its efficacy on osteoporosis. Therefore, we aimed to identify the components of chicken-vegetable bone broth (CVBB) that are associated with osteoporosis prevention and verified the efficacy of these components using in vivo studies. In biochemical and cell biological experiments, CVBB was fractionated using ion exchange chromatography (IEC), and the effect of each IEC fraction on osteoclast differentiation was evaluated based on tartrate-resistant acid phosphatase (TRAP) activity, TRAP staining, and quantitative polymerase chain reaction analysis using mouse macrophage-like cells (RAW264 cell).

Article Synopsis
  • Mutations in Lamin A/C disrupt the structure of cardiomyocytes and contribute to dilated cardiomyopathy (DCM) by trapping the transcription factor TEAD1 at the nuclear membrane.
  • Advanced techniques like single-cell RNA sequencing and ATAC-seq were used to explore the molecular mechanisms behind these mutations, revealing an issue with gene expression regulation.
  • Targeting the Hippo pathway shows promise for correcting the gene dysregulation caused by these mutations, suggesting a potential treatment avenue for patients with DCM linked to this specific mutation.

Unlabelled: Myotonic dystrophy type 1 (DM1) displays a wide range of cardiac manifestations, including conduction system disturbances, arrhythmias, and cardiomyopathy. As a result of progressive myocardial injury and fibrosis, patients with DM1 frequently show electrocardiogram (ECG) abnormalities which sometimes cannot be differentiated from myocardial ischemia. Even in DM1 cases with ECG findings indicative of coronary artery disease, coronary angiography and coronary computed tomography often demonstrate intact coronary arteries.

The ontogeny and fate of stem cells have been extensively investigated by lineage-tracing approaches. At distinct anatomical sites, bone tissue harbors multiple types of skeletal stem cells, which may independently supply osteogenic cells in a site-specific manner. Periosteal stem cells (PSCs) and growth plate resting zone stem cells (RZSCs) critically contribute to intramembranous and endochondral bone formation, respectively.

Southwestern Japan suffered its worst rains in 2018 causing floods and mudslides, claiming 225 lives and forcing millions for evacuations. Referred as "Heisei san-jū-nenshichi-gatsugōu", the disaster was the result of incessant precipitation caused by the interaction of typhoon "Prapiroon" with the seasonal rain front "Baiu". The present epidemiological study aims to investigate disaster-induced health issues in 728 residents of Innoshima island in the Hiroshima Prefecture by comparing their clinical data in pre-disaster (2017) and disaster-hit (2018) years which was obtained from annual health screening.
