Article Synopsis
- This study explores the relationship between heart rate fragmentation (HRF) and coronary artery calcification (CAC) in a general population, particularly focusing on whether these associations are influenced by systolic blood pressure (SBP) levels.
- Researchers used data from a sample of 508 participants who underwent ambulatory blood pressure monitoring and 24-hour Holter monitoring to measure HRF and CAC, with results indicating that higher HRF and SBP are linked to the presence of CAC.
- Findings suggest that elevated HRF and SBP during sleep are associated with increased likelihood of CAC, independent of other factors, highlighting potential risk indicators for cardiovascular health in the general male population.
Understanding the pressure-induced structural changes in liquids and amorphous materials is fundamental in a wide range of scientific fields. However, experimental investigation of the structure of liquid and amorphous material under in situ high-pressure conditions is still limited due to the experimental difficulties. In particular, the range of the momentum transfer (Q) in the structure factor [S(Q)] measurement under high-pressure conditions has been limited at relatively low Q, which makes it difficult to conduct detailed structural analysis of liquid and amorphous material.

Methods: We assessed cross-sectcional associations of anthropometric and CT-based obesity indices with CAC, AoAC, and AVC. Anthropometric measures included body mass index (BMI), waist circumference, hip ircumference, waist-to-hip circumference ratio, and waist-to-height ratio in 931 men (mean age, 63.
Oceanic lithosphere moves over a mechanically weak layer (asthenosphere) characterized by low seismic velocity and high attenuation. Near mid-ocean ridges, partial melting can produce such conditions because of the high-temperature geotherm. However, seismic observations have also shown a large and sharp velocity reduction under oceanic plates at the lithosphere-asthenosphere boundary (LAB) far from mid-ocean ridges.
