Abstract
Studies focusing on the interaction of dietary and acute emotional stress on oxidative stress in cortex frontal and in brain mitochondria are scarce. Dietary-induced insulin resistance, as observed in Western diets, has been associated with increased oxidative stress causing mitochondrial dysfunction. We hypothesized that acute emotional stress could be an aggravating factor by impacting redox status in cortex and brain mitochondria. Thus, the aim of the present study was to evaluate the combination of an insulin resistance inducing high-fat/high-fructose (HF/HFr) diet and acute emotional stress on brain oxidative stress in rats. We measured several oxidative stress parameters (carbonyls, FRAP, TBARS assays, GSH, GSSG, oxidized DNA, mRNA expression of redox proteins (Nrf2), and uric acid). The HF/HFr diet resulted in increased oxidative stress both in the brain mitochondria and in the frontal cortex and decreased expression of the Nrf2 gene. The emotional stress induced an oxidative response in plasma and in brain mitochondria of the control group. In the HF/HFr group it triggered an increase expression of the redox transcription factor Nrf2 and its downstream antioxidant genes. This suggests an improvement of the redox stress tolerance in response to an enhanced production of reactive oxygen species. Accordingly, a blunted oxidative effect on several markers was observed in plasma and brain of HF/HFr-stressed group. This was confirmed in a parallel study using lipopolysaccharide as a stress model. Beside the Nrf2 increase, the stress induced a stronger UA release in HF/HFr which could take a part in the redox stress.

Abstract
BACKGROUND The mechanisms by which hypertonic sodium lactate (HSL) solution act in injured brain are unclear. We investigated the effects of HSL on brain metabolism, oxygenation, and perfusion in a rodent model of diffuse traumatic brain injury (TBI). METHODS Thirty minutes after trauma, anaesthetised adult rats were randomly assigned to receive a 3 h infusion of either a saline solution (TBI-saline group) or HSL (TBI-HSL group). The sham-saline and sham-HSL groups received no insult. Three series of experiments were conducted up to 4 h after TBI (or equivalent) to investigate: 1) brain oedema using diffusion-weighted magnetic resonance imaging and brain metabolism using localized 1H-magnetic resonance spectroscopy (n = 10 rats per group). The respiratory control ratio was then determined using oxygraphic analysis of extracted mitochondria, 2) brain oxygenation and perfusion using quantitative blood-oxygenation-level-dependent magnetic resonance approach (n = 10 rats per group), and 3) mitochondrial ultrastructural changes (n = 1 rat per group). RESULTS Compared with the TBI-saline group, the TBI-HSL and the sham-operated groups had reduced brain oedema. Concomitantly, the TBI-HSL group had lower intracellular lactate/creatine ratio [0.049 (0.047-0.098) vs 0.097 (0.079-0.157); P < 0.05], higher mitochondrial respiratory control ratio, higher tissue oxygen saturation [77% (71-79) vs 66% (55-73); P < 0.05], and reduced mitochondrial cristae thickness in astrocytes [27.5 (22.5-38.4) nm vs 38.4 (31.0-47.5) nm; P < 0.01] compared with the TBI-saline group. Serum sodium and lactate concentrations and serum osmolality were higher in the TBI-HSL than in the TBI-saline group. CONCLUSIONS These findings indicate that the hypertonic sodium lactate solution can reverse brain oxygenation and metabolism dysfunction after traumatic brain injury through vasodilatory, mitochondrial, and anti-oedema effects.

Abstract
Several links relate mitochondrial metabolism and type 2 diabetes or chronic hyperglycaemia. Among them, ATP synthesis by oxidative phosphorylation and cellular energy metabolism (ATP/ADP ratio), redox status and reactive oxygen species (ROS) production, membrane potential and substrate transport across the mitochondrial membrane are involved at various steps of the very complex network of glucose metabolism. Recently, the following findings (1) mitochondrial ROS production is central in the signalling pathway of harmful effects of hyperglycaemia, (2) AMPK activation is a major regulator of both glucose and lipid metabolism connected with cellular energy status, (3) hyperglycaemia by inhibiting glucose-6-phosphate dehydrogenase (G6PDH) by a cAMP mechanism plays a crucial role in NADPH/NADP ratio and thus in the pro-oxidant/anti-oxidant cellular status, have deeply changed our view of diabetes and related complications. It has been reported that metformin has many different cellular effects according to the experimental models and/or conditions. However, recent important findings may explain its unique efficacy in the treatment of hyperglycaemia- or insulin-resistance related complications. Metformin is a mild inhibitor of respiratory chain complex 1; it activates AMPK in several models, apparently independently of changes in the AMP-to-ATP ratio; it activates G6PDH in a model of high-fat related insulin resistance; and it has antioxidant properties by a mechanism (s), which is (are) not completely elucidated as yet. Although it is clear that metformin has non-mitochondrial effects, since it affects erythrocyte metabolism, the mitochondrial effects of metformin are probably crucial in explaining the various properties of this drug.

Abstract
In order to validate xenografted small cell lung carcinomas (SCLC) for biological studies, the authors established 12 lung neuroendocrine (NE) tumors (eight typical SCLC and four atypical NE tumors [ANE]) by heterotransplantation onto nude mice. Their characterization was performed using serial ultrastructural, enzymatic, and immunohistochemical methods on primary tumors and after xenografts. These were subclassified into epithelial (one), neuroendocrine (three), and multidifferenciated (eight) types. The phenotypic characters (cytokeratins, neurofilaments, neurone-specific enolase) and the proliferative rate (Ki 67 labelling) of original tumor were maintained until the last passage studied. Although further acquisition of subsets of cytokeratin or neurofilaments was observed in some cases, the authors could not detect any morphologic and/or biological spontaneous change comparable to those described in in vitro cell lines. In addition, ANE are not quite identical to variant subclasses described in vitro. The authors conclude that the stability of heterotransplanted SCLC is an advantage in further biological studies.

Abstract
Neurone specific enolase (NSE); alpha gamma and gamma gamma isoenzymes of the glycolytic enzyme enolase, is found in considerable quantity in serum of patients with small cell lung cancer (SCLC). The spectrophotometric measurement of serum enolase activity, plus the electrophoretic separation of isoenzymes (alpha alpha, alpha gamma and gamma gamma) using an amplification reaction constitute a simple method, the application of which has not yet been demonstrated. In patients, serum values of higher than 25 U/l of total enolase activity, with more than 10% NSE, were considered to be positive. Seventy patients diagnosed as SCLC were classified before treatment as having either limited (LD) or extensive (ED) disease, and after chemotherapy as being in complete (CR) or partial remission (PR), stable state (SS) or in relapse (R). The levels of enolase activity and NSE (M +/- SE) in these patients (enolase: 67 +/- 7 U/l, NSE 27 +/- 2%) were different from those in a control group of 19 patients with non-small cell lung cancer (enolase: 29 +/- 2 U/l, NSE: 7 +/- 1%) (p less than 0.001) at the time of diagnosis. Mean enolase and NSE levels in patients with SCLC were seen to differ significantly according to the clinical stage. The results of those patients with ED differed from those of patients with LD (p less than 0.001). The results of the group of patients that achieved remission differed from that of patients during relapse (p less than 0.0001). Serial measurements demonstrated a good correlation between enolase and NSE serum levels and the progression of the disease. The usefulness of this method in the early assessment of treatment was also demonstrated. The clinical usefulness of the dosage of NSE with that of two other tumour markers CKBB and mitochondrial CK was compared.

Abstract
A simple method is described which allows easy determination of neuroendocrine (NE) differentiation in human broncho-pulmonary tumor models grown in heterotransplanted nude mice. Enolase (EC 4.2.1.11) isoenzyme composition is studied using the electrophoretic method in xenograft tumor homogenates. The relatively large amount of alpha gamma and gamma gamma isoenzymes (neuron-specific enolase (NSE] is indicative of the neuroendocrine differentiation level of these tumors. The gamma gamma isoenzyme is present at a high level (M +/- SE: 10 +/- 2%) in all NE tumor models and absent in non NE tumor models. The alpha gamma isoenzyme is found in a significantly higher proportion in NE tumor models (30 +/- 2%) than in non NE tumor models (9 +/- 2%) (p less than 0.001). Moreover it is possible to discriminate between human and mice isoenzymes to estimate the proportion of mouse tissue hat is present in the xenograft.

Abstract
Electrophoretic separation of enolase isoenzymes and the measurement of enolase activity were performed in 25 lung tumor extracts. In 13 neuroendocrine (NE) tumors (nine small cell lung carcinoma [SCLC], three atypical NE tumors, and one carcinoid tumor), the NE differentiation was assessed by ultrastructural determination of neurosecretory granule (NSG) density. Twelve non-NE lung tumors also were studied (three adenocarcinomas, four epidermoid, two composite, two large cell undifferentiated carcinomas, and one lymphoma). Four normal lung tissues and 1 human brain were used as controls. The gamma gamma isoenzyme was present at a high level (mean +/- SE, 12 +/- 3%) in all NE carcinomas and consistently absent in all non-NE tumors as well as in normal lung. The alpha gamma isoenzyme was found in significantly higher proportion in NE carcinomas (mean +/- SE, 29 +/- 2%) than in non-NE tumors (mean +/- SE, 8 +/- 1%) (P less than 0.0001), despite an equally high level of total enolase activity in both groups of tumor. The separation of alpha gamma and gamma gamma isoenzymes of enolase allows for the accurate diagnosis of NE tumors and NE components of atypical NE carcinomas, and the gamma gamma isoenzyme, in contrast to gamma chain detection by immunoassay, can be considered to be a specific marker in itself of NE differentiation in lung neoplasms.
