A Novel Method to Determine the Respiratory Compensation Point from Percutaneous Oxygen Saturation of Healthy Adults During a Ramp-Incremental Test: A Cross-Sectional Study

Medical Sciences
Background: In exercise testing, the ventilatory threshold 1 (VT1) and ventilatory threshold 2 (VT2) are used in lifestyle-related diseases, cardiac rehabilitation, and athletic training.

[Ventilatory threshold in patients with chronic glomerulonephritis].

Nihon Jinzo Gakkai shi, 1993
To evaluate cardiorespiratory endurance of patients with chronic glomerulonephritis (CGN), ventilatory threshold oxygen uptake (VT) was measured in 69 patients with chronic glomerulonephritis and 337 healthy subjects (male: 140, female: 197) varying in age from 15 to 86 yrs.

Closed‐Loop Radiative Cooling Mulch Upcycled From Agricultural Residues for Efficient Soil Heat–Water Stress Mitigation

Advanced Science, EarlyView.
Conventional passive radiative cooling films rely on costly feedstocks and energy‐intensive fabrication, with poor end‐of‐life compatibility in agriculture. To address this challenge, a sustainable radiative cooling mulch (SRCM) is developed from waste maize leaves via spontaneous hydrogen‐bond self‐assembly.
