To test the hypothesis that in chronic obstructive pulmonary disease (COPD) patients the ventilatory and metabolic requirements during cycling and walking exercise are different, paralleling the level of breathlessness, we studied nine patients with moderate to severe, stable COPD. Each subject underwent two exercise protocols: a 1-min incremental cycle ergometer exercise (C) and a "shuttle" wa...

Extensive resection of small bowel often leads to short bowel syndrome (SBS). SBS patients develop clinical mal-absorption and dehydration relative to the reduction of absorptive area, acceleration of gastrointestinal transit time and modifications of the gastrointestinal intra-luminal environment. As a consequence of severe mal-absorption, patients require parenteral nutrition (PN). In adults,...

In response to clinical demand some point-of-care analysers now provide blood lactate measurements, but recently concern has been expressed about the value and interpretation of these measurements. We undertook this study to evaluate blood lactate measurements in patients with acute renal failure undergoing haemofiltration (HF) with lactate replacement fluid. At baseline, 27 patients had base d...

The fluorolytic sol–gel synthesis is applied with the intention to obtain two different types of core–shell nanoparticles, namely, SrF2–CaF2 and CaF2–SrF2. In separate fluorination steps for core shell formation, corresponding metal lactates are reacted anhydrous HF in ethylene glycol. Scanning transmission electron microscopy (STEM) dynamic light scattering (DLS) confirm formation particles me...

The study highlights the fungal diversity of traditional Algerian date’s product “Btana” prepared with direct Btana method (DBM) and undirect (UBM). populations were analyzed through 28S metabarcoding. Data treatment resulted in 122,997 reads representing three Phyla which 76% (46 OTUs) belong to Ascomycota phylum. Zygosaccharomyces rouxii was most prevailed species accounting for 35.40% total ...

Kline, Leo (University of California, Berkeley), L. Pine, and H. A. Barker. Metabolic role of the BR factor in Butyribacterium rettgeri. J. Bacteriol. 85:967-975. 1963.-The BR factor, which is replaceable by lipoic acid, was shown to be required for the decomposition of lactate by Butyribacterium rettgeri. Since the factor was not required for the fermentation of pyruvate or glucose by this org...

Lactate formation from fructose-1,6-diphosphate in homogenates of Sarcoma 180 from mice, given injections intraperitoneally of 6-mercaptopurine, was sharply de creased as compared with that in tumor homogenates of nontreated animals. The activities of aldolase and triosephosphate isomerase, but not of phosphoglyceraldehyde dehydrogenase and phosphoglyceric acid kinase, were significantly lower,...

MILLER, H. I., B. ISSEKUTZ, JR., P. PAUL, AND K. RODAHL. Effect of lad tic acid on plasma free fatty acids in pancreatectomized dogs. Am. J. Physiol. 207(6): 1226-1230. rg64.-Sodium lactate infusions into unanesthetized pancreatectomized dogs, with indwelling arterial and venous catheters, markedly decreased the plasma free fatty acid (FFA) level. Infusions of palmitate-rCl4 at constant rates s...

Aim: The aim of this study was to ascertain if a score, directly derived from CPB records, could correlate to major postoperative outcomes. Methods: An additive score (QualyPscore) was created from 10 parameters: peak lactate value during CPB, peak VCO2i, lowest DO2i/VCO2i, peak respiratory quotient, CPB time, cross-clamp time, lowest CPB temperature, circulatory arrest, ultrafiltration during ...
