These molecules remain in a semi-liquid state, providing lubrication regardless of stress towards the ice exerted by any object. However, the importance of this hypothesis is disputed by experiments exhibiting a excessive coefficient of friction for ice utilizing atomic force microscopy. A 3rd idea is “friction heating”, which suggests that friction of the fabric is …
As a matter both of utilization choices within the medical literature and of idiom in pure language, the words tachycardia and tachyarrhythmia are often used interchangeably, or loosely sufficient that precise differentiation will not be specific. The distinction is that tachycardia be reserved for the fast coronary heart rate itself, regardless of cause, physiologic or …
Mutations in 5 genes have been shown to cause dopamine-responsive dystonia. The precursor of the neurotransmitter dopamine, L-dopa, is synthesised from tyrosine by the enzyme tyrosine hydroxylase and utilises tetrahydrobiopterin (BH4) as a cofactor. A mutation in the gene GCH1, which encodes the enzyme GTP cyclohydrolase I, disrupts the manufacturing of BH4, decreasing dopamine ranges …
