It is well known that isotopic tracer st,udies of a complex system of interrelated reactions can determine the existence and magnitude of reaction sequences for transferring atoms from a given reactant to a particular product and also in many cases, usually through studies involving asymmetrically labeled reactants and including degradation of the products, establish parameters with which postu...

It has been hypothesized that respiration defects caused by accumulation of pathogenic mitochondrial DNA (mtDNA) mutations and the resultant overproduction of reactive oxygen species (ROS) or lactates are responsible for aging and age-associated disorders, including diabetes and tumor development. However, there is no direct evidence to prove the involvement of mtDNA mutations in these processe...

The time when blood lactate reaches peak concentration following maximum exercise is unclear. The post exercise venous blood lactate concentration was determined serially for 30 minutes in 13 trained men following maximum exercise on a motor driven treadmill. Lactates were determined enzymatically in duplicate. The VO2 max and percent body fat was 65.1 +/- 4.8 ml.kg-1.min-1 and 11.4 +/- 1.4, re...

Abstract Background and Aims Sepsis septic shock are quite common events in the hospital setting. The classification of these has changed a lot over years, to ensure better sensitivity recognizing situation that, if not managed properly quickly, leads death patient. In our study we focused on search for predictors acute kidney injury mortality during evolution this pathology, with particular at...

With advances in the study of human microbiome, fact that lactate is smallest chiral molecule nature has drawn attention. However, there have been few comparative studies on classification L-lactate and D-lactate. In this study, we investigated safety efficacy D-lactate as an immunomodulator food origin. terms evaluation, both lactates were found to promote cell proliferation repair. was well t...

I g63.mThe metabolism of glucose CT-Cl”, 5 mM, and palmitate I-(?~, 0.75 mM (complexed to o.j’:i;: albumin), was studied in isolated perfused hearts taken from three groups of rats: fed ad libitum, fasted overnight, or fasted 4 d...

This study assessed the effectiveness of water immersion to the shoulders in enhancing blood lactate removal during active and passive recovery after short-duration high-intensity exercise. Seventeen cyclists underwent active water- and land-based recoveries and passive water and land-based recoveries. The recovery conditions lasted 31 minutes each and started after the identification of each c...

Bacteriol. 87:924-932. 1964.-Arthrobacter crystallopoietes exhibits the cyclic, morphological variation which is a characteristic of this genus. A simple chemically defined medium was developed in which this organism is restricted to growth and division ...

As a preliminary to preparing bacteriophages marked with C14, it was desirable to ascertain which singly-labeled lactic acid, when used as a carbon source, gives the highest incorporation of radioactive carbon in the celLs of Escherichia coli. The results, while not unexpected, present several interesting features and serve to supplement the much more complete data obtained by Wiame and Doudoro...
