evolution in atmospheric and oceanic gasses [1,6], particularly the timing of oxygenation and the GOE currently dated at 2.3 Ga [1,4,6], the increasing generation of O2 in the atmosphere during this period was in fact a major atmospheric pollutant that affected biological life on earth [13...
Background and objective: The aim of this study was to evaluate the effects of increased oxygen availability on gene expression and on collagen deposition/maturation in the periodontium following disease. Material and methods: Male Wistar rats had ligatures placed around their molars to induce perio...

Irradiation of a quartz reaction vessel with a carbon arc, from which the infrared was filtered by interposed water, very greatly shortened the induction period and accelerated the rate of the nonexplosive reaction, but did not shift the positions of the L.C.C. and U.C.C. The last ...
1g and Extended Data Figs. 1m,p). Notably, the number of circulating plasmatocytes and crystal cells naturally recovered to normal levels after 5 to 7 h of hypoxia, followed by subsequent oscillations, creating a damped oscillatory-like pattern over the 24 h period (Extended Data Fig. ...
The Oxygen Market size is estimated at 562.81 million tons in 2025, and is expected to reach 704.39 million tons by 2030, at a CAGR of 4.59% during the forecast period (2025-2030). The increasing demand for oxygen in the medical and healthcare sector and the growing demand for oxygen in...

Oxygen saturation was less than 30% in 12 neonates and less than 50% in 26 neonates at some time during the 15-min monitoring period. In term infants, preductal SpO2 values have been reported to be approximately 5–10% higher than postductal values in the first 5 min of life (33,34)...
Effect on Oxygenation Oxygen treatment resulted in a significant increase of 0.8% in the highest oxygen saturation and 0.9% in the lowest oxygen saturation during the 72 hours of the intervention period in the continuous oxygen group compared with controls, and of 0.5% in the highest oxygen satur...
Ninety-two children undergoing long auditory assessments were randomly assigned to two study arms: CHS (n = 40) and GA (n = 52). Data of 81 children (mean age 13.8 months, range 1–36 months) were analyzed. In the GA group, we followed a predefined 10 N concept (...
