Industrial pollutants act directly as toxic substances, causing impairment in metabolic functions and eventually mortality.
They can also modify plasma membrane fluidity [ 20] as well as disrupt cellular ionic homeostasis, leading to a reduction of metabolic activity and eventually cell death.
Chronic damage to hepatocytes by viral infection (hepatitis B or C) or excessive alcohol consumption can lead to liver cirrhosis, which consists of extensive fibrosis, loss of metabolic function and, eventually, death.
34 Sarcopenia demands a greater effort from older people to perform daily activities, with an increase in energy expenditure and cardiovascular and metabolic overload, eventually increasing the risks of transitioning to frailty, characterized by a reduction in functional reserve.
Absence of a vitamin blocks one or more specific metabolic reactions in a cell and eventually may disrupt the metabolic balance within a cell and in the entire organism as well.
Early initiation of hypothermia may improve this full spectrum of cellular failure, improve brain glucose and energy metabolism and reduce lactate accumulation; with this, intracellular and intercellular acidosis will improve and eventually metabolic recovery be enhanced [ 4, 19- 21].
Obesity and body fat distribution are important determinant of glucose homeostasis [2], [3] with insulin resistance as the main contributor to the deleterious consequences of obesity, such as development of metabolic diseases, IGT, T2D and eventually cardiovascular disease [4].
Since the same enzymes regulate nuclear gene expression during long term alterations in the calcium signals, they thus regulate differentiation, growth, metabolic and functional specializations, and eventually shape the phenotype of the muscle cells during development and pathogenesis [ 3, 4].
In particular, a number of seminal PET studies have demonstrated the existence of critical CBF thresholds and duration below which functional and metabolic processes are disturbed and eventually cease [ 14, 18, 19, 27– 30].
The main clinical and biochemical presentation in affected patients includes neurological impairment, hypoglycemia, vomiting, jaundice, renal tubular dysfunction, liver failure, hepatomegaly, metabolic acidosis, seizures, coma, and eventually death [ 4– 9].
