OER increases with the ageing of the cell cycle. For example, cells in G1 phase have a lower OER than in the S phase. This is because G1 phase are more radiosensitive as shown in Figure 2. The high sensitivity of G1 phase compared to S phase is due to tenderness of chromosomes in...

Their results showed that the activities of TCA cycle enzymes decreased with the decrease in oxygen supply. As a result, a 30% increase in lysine yield due to increased phosphoenol pyruvate (PEP) carboxylation was achieved for the microaerobic culture (5% DO) as compared with aerobic ...
Cells living under aerobic conditions always face oxygen paradox. Oxygen is necessary for cells to maintain their lives. However, reactive oxygen species such as Superoxide radical (O-2, hydroxyl radical (OH−) and hydrogen peroxide (H2O2) are generated from oxygen and damage cells. Oxidative st...
Blood oxygen saturation (SpO2/SaO2), a crucial indicator of the respiratory cycle, refers to the percentage of the HbO2 oxygen binding capacity in the blood to the total capacity of Hb that can be bound by oxygen. SpO2 refers to the oxygen saturation measured by pulse oximetry, while SaO2 ...
Oxygen combines with most elements, is required for combustion, and is essential for life in most organisms. Atomic number 8. See Periodic Table. Word History In 1786, the French chemist Antoine Lavoisier coined a term for the element oxygen (oxygène in French). He used Greek words for the...
13, the peak value of the carbon conversion rate attained at the 10th cycle for Cu-C-20 was 0.042 s-1, while it was 0.019 s-1 for pure copper ore, at 950 °C. Moreover, the cycled copper ore agglomerated seriously, yet no obvious sintering phenomenon occurred to the Cu-C-20 ...
