  • Nitrogen
  • A particularly important intermediate in the chemical industry, nitric oxide forms in mixtures of nitrogen and oxygen at high temperatures, as found in combustion systems such as internal-combustion piston engines, gas turbines, furnaces, and boilers. (wikipedia.org)
  • When exposed to oxygen, nitric oxide is converted into nitrogen dioxide. (wikipedia.org)
  • The nitric oxide reacts with the ozone to produce oxygen and nitrogen dioxide, accompanied with emission of light (chemiluminescence): ·NO + O3 → NO2 + O2 + hν which can be measured with a photodetector. (wikipedia.org)
  • species
  • First, it clearly demonstrates the key role of mitochondrially produced reactive oxygen species in the process of ageing of mammals. (eurekalert.org)
  • Since this species is an obligately aquatic neotene, retains its gills through its adult life, it must absorb oxygen through its gills or skin. (wikipedia.org)
  • They theorized two explanations for this reaction: low and high DO levels may be found relatively close, therefore movement will allow this species to migrate to a higher DO environment, the physical movement causes a decrease between boundary layers adjacent to skin and gills, which allows for greater flow of oxygen. (wikipedia.org)
  • The species affects the composition of the phytoplankton community by decreasing the biomass of mostly toxic cyanobacteria and flagellates and promoting the biomass of mostly colonial green algae. (wikipedia.org)
  • A decrease in the ratio has been found to increase the competitive ability of sperm in Mus species. (wikipedia.org)
  • increase
  • The effects of this change are 1) an increase in sperm hydrodynamics for better flow through liquids by reducing the head size 2) decrease in the occurrence of DNA damage 3) removal of the epigenetic markers that occur with histone modifications. (wikipedia.org)
  • The Hedgehog cascade acts to increase D2 ubiquitination through WSB1 activity, decreasing D2 activity. (wikipedia.org)
  • toxic
  • Its consumption of cyanobacteria during algal blooms may result in bioaccumulation of toxic microcystins (microcystin-LR, microcystin-RR) from Microcystis in the gonads, the hepatopancreas and the digestive tract. (wikipedia.org)
  • production
  • Cytochalasin-B stimulated zymosan induced oxygen consumption and hydrogen-peroxide release by 98.5 and 44 percent, respectively, but had no effect on O2- production. (cdc.gov)
  • levels
  • Dissolved oxygen (DO) is required at specific levels to maintain healthy aquatic life. (wikipedia.org)
  • D3 levels are highest early in development and decrease over time, while D2 levels are high at moments of significant metamorphic change in tissues. (wikipedia.org)
  • high
  • In these cases, hearing loss normally appears before the onset of diabetes and is marked by a decrease in perception of high tone frequencies. (wikipedia.org)
  • Rapid
  • 5. - 6 In cancer, for example, abnormal metabolism fuels rapid cellular growth while maintaining relative insensitivity to oxygen supply. (spiedigitallibrary.org)
  • lack
  • Apart from prenatal developments, physiological responses may also arise from a lack of oxygen. (wikipedia.org)
  • Type
  • Susceptibility of ICR mice to intravaginal inoculation of herpes simplex virus type 2 (HSV-2) decreases with age. (unt.edu)
  • left
  • a Oxygen consumption rates of fibroblasts from indicated group under basal conditions (left), in the presence of oligomycin (center), or in the presence of FCCP (right). (nih.gov)
  • If left untreated, 25-30% of patients affected by diabetic macular edema (DME) experience a 15-letter decrease in visual acuity (VA) score within 3 years [ 4 ]. (hindawi.com)
