Abstract
Monitoring of lactate is spreading from the evident clinical environment, where its role as a biomarker is notorious, to the agrifood ambit as well. In the former, lactate concentration can serve as a useful indicator of several diseases (e.g., tumour development and lactic acidosis) and a relevant value in sports performance for athletes, among others. In the latter, the spotlight is placed on the food control, bringing to the table meaningful information such as decaying product detection and stress monitoring of species. No matter what purpose is involved, electrochemical (bio)sensors stand as a solid and suitable choice. However, for the time being, this statement seems to be true only for discrete measurements. The reality exposes that real and continuous lactate monitoring is still a troublesome goal. In this review, a critical overview of electrochemical lactate (bio)sensors for clinical and agrifood situations is performed. Additionally, the transduction possibilities and different sensor designs approaches are also discussed. The main aim is to reflect the current state of the art and to indicate relevant advances (and bottlenecks) to keep in mind for further development and the final achievement of this highly worthy objective.

Abstract
We developed a novel and straightforward derivatization method for the determination of lactate by reversed phase high-performance liquid chromatography (RP-HPLC) with fluorescence and UV detection in biological matrices as urine and saliva. The derivatization of lactate was achieved employing 9-chloromethyl anthracene (9-CMA) as fluorescence reagent, which has never been previously used to obtain a lactate derivative. Lactate reacts with 9-CMA with high selectivity in a very short time, without requiring extraction procedures from the aqueous solution, and the reaction reaches 70% completion in 30 min. The ester derivative obtained can be easily determined by RP-HPLC with fluorescence detection at 410 nm (λ ex=365 nm) and UV detection at 365 nm. The method was also optimized in order to allow for the simultaneous determination of lactate and creatinine for the application to urine samples. The lactate calibration curve was linear in the investigated range 2 × 10(-4)-3 × 10(-2)mM and the limit of detection, calculated as three times the standard deviation of the blank divided by the calibration curve slope, was 50 nM for both fluorescence and UV detection. Intra-day and inter-day repeatability were lower than 5% and 6%, respectively. The method proposed was successfully applied to the analysis of urine and saliva samples.

Abstract
Pesticide exposure during brain development could represent an important risk factor for the onset of neurodegenerative diseases. Previous studies investigated the effect of permethrin (PERM) administered at 34 mg/kg, a dose close to the no observable adverse effect level (NOAEL) from post natal day (PND) 6 to PND 21 in rats. Despite the PERM dose did not elicited overt signs of toxicity (i.e. normal body weight gain curve), it was able to induce striatal neurodegeneration (dopamine and Nurr1 reduction, and lipid peroxidation increase). The present study was designed to characterize the cognitive deficits in the current animal model. When during late adulthood PERM treated rats were tested for spatial working memory performances in a T-maze-rewarded alternation task they took longer to choose for the correct arm in comparison to age matched controls. No differences between groups were found in anxiety-like state, locomotor activity, feeding behavior and spatial orientation task. Our findings showing a selective effect of PERM treatment on the T-maze task point to an involvement of frontal cortico-striatal circuitry rather than to a role for the hippocampus. The predominant disturbances concern the dopamine (DA) depletion in the striatum and, the serotonin (5-HT) and noradrenaline (NE) unbalance together with a hypometabolic state in the medial prefrontal cortex area. In the hippocampus, an increase of NE and a decrease of DA were observed in PERM treated rats as compared to controls. The concentration of the most representative marker for pyrethroid exposure (3-phenoxybenzoic acid) measured in the urine of rodents 12 h after the last treatment was 41.50 μg/L and it was completely eliminated after 96 h.

Abstract
Soy peptones or soy hydrolysates are widely used as key medium additives in serum-free cell culture processes for industrial production of therapeutic recombinant proteins. The heterogeneous nature of these vegetable-derived materials can lead to substantial lot- to-lot variability in cell culture processes. In this study, we demonstrated the feasibility of nuclear magnetic resonance (NMR) spectroscopy in combination with chemometrics in rapid screening peptone lots in order to optimize efficiency and consistency of large-scale protein production. This report is the first that shows a correlation between the intrinsic NMR spectral characteristics of complex heterogeneous materials and product titer using chemometrics.

Abstract
Metabolic acidosis can result from accumulation of organic acids in the blood due to anaerobic metabolism or intestinal bacterial fermentation of undigested substrate under certain conditions. These conditions include short-bowel syndrome, grain overfeeding of ruminants and, as recently reported, severe gastroenteritis. Measuring fermentation products such as short-chain fatty acids (SCFAs) and lactic acid in various biological samples is integral to the diagnosis of bacterial overgrowth. Stereospecific measurement of D- and L-lactic acid is necessary for confirmation of the origin and nature of metabolic acidosis. In this paper, methods for the separation of SCFAs and lactic acid are reviewed. Analysis of the organic acids involved in carbohydrate metabolism has been achieved by enzymatic methods, gas chromatography, high-performance liquid chromatography and capillary electrophoresis. Sample preparation techniques developed for these analytes are also discussed.

Abstract
BACKGROUND AND AIMS Short-chain fatty acids (SCFAs) are main fuels of the colonic epithelium, and are avidly absorbed by the colon of animal and man. The current knowledge on colonic metabolism and absorption of medium-chain fatty acids (MCFAs) is limited. In some clinical situations, colonic absorption of high-energy substances could compensate for reduced absorptive capacity because of a shortened or malfunctioning small bowel. We evaluated and compared colonic absorption and metabolism of MCFAs (octanoate, decanoate, and dodecanoate), SCFAs (acetate and butyrate), and long-chain fatty acids (LCFAs) (oleate). METHODS Rats were surgically operated on to cannulate a 7-cm segment of proximal colon, isolate the vasculature, and cannulate the right colic vein draining this segment. The lumen was perfused with (14)C-labeled substrates for 100 minutes. Right colic vein blood was analyzed for total (14)C, (14)CO(2), and metabolites by scintillation counting and high-performance liquid chromatography. RESULTS The transport from the colonic lumen to mesenteric blood of substrate carbon from MCFAs exceeded by 2-13-fold that of SCFAs and LCFAs. The CO(2) production from the oxidation of MCFAs was as high as or higher than that from SCFAs. CO(2) produced from the LCFA, oleate, was lower than from SCFAs or MCFAs. In addition to CO(2), ketone bodies were major metabolites of SCFAs and MCFAs. Ketogenesis from butyrate and the MCFAs was significantly higher than from acetate and oleate. A substantial proportion (50%-90%) of all substrates was absorbed without being metabolized. CONCLUSIONS The colonic epithelium serves to absorb and partially metabolize MCFAs. For patients with a compromised small-bowel function, colonic absorption of MCFAs could represent an important way of receiving calories.

Abstract
The Automated In Vitro Dermal Absorption (AIVDA) HPLC method developed in our laboratory for finite dose tests was developed further for infinite dose swimming/bathing exposure tests and for monitoring skin viability during the permeation assay. Skin absorption of the herbicide atrazine was tested under both finite and infinite dose conditions and the data compared to that obtained using the Bronaugh flow-through cell. Confirmation that skin viability was maintained throughout the AIVDA 24-hr infinite dose tests without phenol was obtained using a novel Radio-HPLC method that was developed to monitor glycolytic 14C-lactic acid formation in 14C-glucose spiked receiver solution. Advantages of the AIVDA method (e.g. rapid, sensitive, versatile, cost-effective analysis) together with its disadvantages (e.g. need for manual dexterity, lack of receiver albumin, compound retention time, limit of sampling interval) are discussed.

Abstract
The presence of lactate oxidase was examined in eight Streptococcus species and some related species of bacteria. A clone (pGR002) was isolated from a genomic library of Streptococcus iniae generated in Escherichia coli, containing a DNA fragment spanning two genes designated lctO and lctP. We show that these genes are likely to be involved in the L-lactic acid aerobic metabolism of this organism. This DNA fragment has been sequenced and characterized. A comparison of the deduced amino acid sequence of LctP protein demonstrated that the protein had significant homology with the L-lactate permeases of other bacteria. The amino acid sequence of the LctO protein of S. iniae also showed a strong homology to L-lactate oxidase from Aerococcus viridans and some NAD-independent lactate dehydrogenases, all belonging to the family of flavin mononucleotide-dependent alpha-hydroxyacid-oxidizing enzymes. Biochemical assays of the gene products confirm the identity of the genes from the isolated DNA fragment and reveal a possible role for the lactate oxidase from S. iniae. This lactate oxidase is discussed in relation to the growth of the organism in response to carbon source availability.

Abstract
To determine the influence of substrate concentration and substrate interactions on short-chain fatty acid metabolism in vivo, a surgical procedure was established. Rats were surgically operated to cannulate a 5-cm segment of proximal colon, isolate the vasculature, and cannulate the right colic vein draining this segment. Thus metabolism was restricted to the defined colonic segment. The appearance of total (14)C and (14)CO(2) in the mesenteric blood stabilized after 30 min of perfusion. Increasing luminal concentrations of butyrate from 2 to 40 mmol/l resulted in linear increases in total (14)C, but (14)CO(2) production from [(14)C]butyrate increased as a function of concentration only up to 10 mmol/l and was stable at higher butyrate concentrations. In addition to CO(2), 3-hydroxybutyrate and lactate were major metabolites of acetate and butyrate in vivo. The presence of a mixture of alternative substrates in the lumen had no influence on the metabolism of butyrate to CO(2) but significantly reduced the metabolism of acetate to CO(2). When compared with young (4 mo old) animals, transport of butyrate was significantly lower for aged (48 mo old) animals, as evidenced by the rate of appearance in blood of total (14)C (P = 0.04) and (14)C in butyrate (P = 0.03), but metabolism was similar, since differences were not significant for (14)C in the major metabolites 3-hydroxybutyrate (P = 0.06) and CO(2) (P = 0.17). These results show that important aspects of short-chain fatty acid transport and metabolism are not predicted from data using isolated colonocytes but require study using an in vivo model.
