How does oxygen therapy work?
Oxygen therapy increases the arterial pressure of oxygen and is effective in improving gas exchange and oxygen delivery to tissues , provided that there are functional alveolar units. Oxygen plays a critical role as an electron acceptor during oxidative phosphorylation in the electron transport chain through activation of cytochrome c oxidase (terminal enzyme of the electron transport chain). This process achieves successful aerobic respiration in organisms to generate ATP molecules as an energy source in many tissues. Oxygen supplementation acts to restore normal cellular activity at the mitochondrial level and reduce metabolic acidosis. There is also evidence that oxygen may interact with O2-sensitive voltage-gated potassium channels in glomus cells and cause hyperpolarization of mitochondrial membrane.
How does oxygen therapy help with cellular oxygenation?
Oxygen therapy improves effective cellular oxygenation , even at a low rate of tissue perfusion. Oxygen molecules adjust hypoxic ventilatory drive by acting on chemoreceptors on carotid bodies that sequentially relay sensory information to the higher processing centers in brainstem. It also attenuates hypoxia-induced mitochondrial depolarization that generates reactive oxygen species and/or apoptosis. Studies investigating on hyperbaric oxygen therapy has shown that oxygen supplementation can induce neural stem cell proliferation in neonatal rats thus promoting neurological regeneration after injuries. CD34+, CD45-dim leukocytes are also potential targets for hyperbaric oxygen therapy benefit as their mobilization was increased in vitro which could facilitate the acceleration of recovery at peripheral sites.

What is the periodic table?
The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. The electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. Knowledge of the electron configuration of different atoms is useful in understanding the structure of the periodic table of elements.
What is the symbol for electronegativity?
Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract electrons towards this atom. For this purposes, a dimensionless quantity the Pauling scale, symbol χ, is the most commonly used.
How to determine the stability of an isotope?
To determine the stability of an isotope you can use the ratio neutron/proton (N/Z). Also to help understand this concept there is a chart of the nuclides, known as a Segre chart. This chart shows a plot of the known nuclides as a function of their atomic and neutron numbers. It can be observed from the chart that there are more neutrons than protons in nuclides with Z greater than about 20 (Calcium). These extra neutrons are necessary for stability of the heavier nuclei. The excess neutrons act somewhat like nuclear glue. Only two stable nuclides have fewer neutrons than protons: hydrogen-1 and helium-3.
What is the density of a substance?
Since the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance, it is obvious, the density of a substance strongly depends on its atomic mass and also on the atomic number density (N; atoms/cm 3 ),
How many oxidation states are there?
Oxidation states are typically represented by integers which may be positive, zero, or negative. Most elements have more than one possible oxidation state. For example, carbon has nine possible integer oxidation states from −4 to +4.
What is the boiling point of a substance?
The boiling point of a substance is the temperature at which this phase change (boiling or vaporization) occurs. The temperature at which vaporization (boiling) starts to occur for a given pressure is also known as the saturation temperature and at this conditions a mixture of vapor and liquid can exist together. The liquid can be said to be saturated with thermal energy. Any addition of thermal energy results in a phase transition. At the boiling point the two phases of a substance, liquid and vapor, have identical free energies and therefore are equally likely to exist. Below the boiling point, the liquid is the more stable state of the two, whereas above the gaseous form is preferred. The pressure at which vaporization (boiling) starts to occur for a given temperature is called the saturation pressure. When considered as the temperature of the reverse change from vapor to liquid, it is referred to as the condensation point.
How are atoms determined?
The chemical properties of the atom are determined by the number of protons, in fact, by number and arrangement of electrons. The configuration of these electrons follows from the principles of quantum mechanics. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. In the periodic table, the elements are listed in order of increasing atomic number Z.
