Speculation about possible causes focuses on the use of chemicals in fish farming and on poor oxygen levels in water because of overcrowding of oysters in cages.
The researchers believe that PDP2 helps people adjust to poor oxygen levels by promoting aerobic cellular respiration.
Individuals with CMS had significantly lower PDP2 expression than those without the condition, regardless of ethnic group, suggesting that the gene helps individuals acclimatize to poor oxygen levels.
This can lead to fragmented, poor sleep as well as reduced oxygen levels, which can worsen such medical conditions as high blood pressure and diabetes and increase your risk of heart attack and stroke.
In his practice, asthma cases are up by 40-45% in the last five years, poor lung function is common, and lowered oxygen levels caused by breathing difficulties can lead to long-term problems with vision, growth and brain development, says the paediatrician.
This results in fragmented, poor sleep, as well as low blood oxygen levels.
Dams can also alter the temperature and oxygen levels of the water, which leads to poor water quality.
In a person in poor health or with a weak immune system, untreated pneumonia can cause oxygen levels to fall so far that body tissue is starved – particularly in the heart and brain – of the oxygen it needs to function.
The study also discovered that dissolved oxygen levels in the water were low because there were few organisms, poor sediment, and little plant life in the river.
ISO induces cardiac necrosis by several mechanisms, including increased oxygen consumption, poor oxygen utilization, increased calcium overload and accumulation, altered myocardial cell metabolism, increased myocardial cAMP levels, deranged electrolyte milieu, altered membrane permeability, intracellular acidosis, and increased levels of lipid peroxides [ 10].
Low oxygen levels and, eventually, high carbon dioxide levels in the blood can occur from poor gas exchange due to decreased ventilation from airway obstruction, hyperinflation and a reduced desire to breathe.
