The gradient for lactate drives lactate out of the T tubule towards the interstitium.
Increased lactate/glucose (L/Glc) ratio reflects sustained lactate production driven by hypoxia-induced and ischemia-induced hyperglycolysis encountered following TBI [ 24- 27] and unmasks functional adaptation processes.
As lactate production continues to increase, host responses to lactate may drive cannibalization of protein from muscle, which in the absence of cancer is the source of most lactate production.
The question of whether this lactate rise is driven by fetal hypoxia or derived from the mother was investigated by studying the arterio-venous lactate difference at birth.
Recent interest into lactate-driven conditioning programmes has driven this review which provides a summary of equine protocols used to date and their responses.
Exhaustive exercise raises arterial plasma lactate levels up to 15 20 mmol/l (Dalsgaard, 2006; Quistorff et al., 2008) and drives lactate into the entire brain, thereby eliminating most or all endogenous lactate gradients.
Since lactate transport is passive and concentration-gradient driven, there must have been compartmentation of brain lactate.
Data suggest that dry matter intake (DMI) and digestibility of nutrients are major factors influencing nutrient utilization in dairy cattle, yet in lactating dairy cows, DMI is driven by the production of milk but sometimes limited by physical fill and metabolic effects (Allen 2000).
However, lactate may also accumulate during accelerated aerobic glycolysis driven by Ep [ 35], and it is unlikely that the rise in plasma lactate level is due to an excessive vasoconstrictor effect via Ep α-adrenergic receptor stimulation, given the low doses administered.
Excessive lactate production in our patients with acute PE is probably driven by two mechanisms, ischemia-reperfusion injury and the systemic inflammatory response, which both cause severe cell damage.
It was shown that the SMBR is a very attractive technology for the production of ethyl lactate, since under appropriate conditions the lactic acid conversion can be driven to completion and productivity as high as 32KgEL/(Ladsday) and purity of 95% can be obtained.
