The distinctive properties of Brucella outer membrane have been considered to be critical for Brucella sp. virulence. Among the outer membrane molecules possibly related to these properties, Omp10 and Omp19 are immunoreactive outer membrane lipoproteins. Moreover, these proteins of Brucella could constitute a new family of outer membrane proteins specifically encountered in the family RHIZOBIACEAE: We evaluated the impact of omp10 or omp19 deletion on Brucella abortus outer membrane properties and virulence in mice. The omp10 mutant was dramatically attenuated for survival in mice and was defective for growth in minimal medium but was not impaired in intracellular growth in vitro, nor does it display clear modification of the outer membrane properties. Significantly fewer brucellae were recovered from the spleens of mice infected with the omp19 mutant than from those of mice infected with the parent strain at 4 and 8 weeks postinfection. The omp19 mutant exhibited an increase in sensitivity to the polycation polymyxin B and to sodium deoxycholate. These results indicate that inactivation of the omp19 gene alters the outer membrane properties of B. abortus. [less ▲]

Two methods were tested for suppressing the depressive effect of N-free diets on the digestive secretions in pigs: the blood perfusion of amino acids (AA) or the peptide alimentation method. In the latter, enzymically hydrolysed casein (EHC), composed of oligopeptides and free AA, was used as the source of nitrogen. The unabsorbed dietary N molecules were discarded from the ileal digesta by ultrafiltration or gel filtration, assuming that the endogenous fraction did not contain significant amounts of small molecules. The AA supply by blood perfusion had no effect on the ileal endogenous AA losses (8.0 g AA kg-' DM intake) in growing pigs (k 50 kg), compared with the N-free diet alone (8.3 g), whereas the EHC supplementation significantly increased them (18.0 8). The increase was due to both endogenous and dietary N. The presence of unabsorbed dietary AA in the ileal digesta was confirmed by the AA profile of the soluble molecules with a very low molecular mass (< 3 kDa), which was close to that of EHC. Both ultrafiltration (cut-offs of 3 or 10 kDa) and gel filtration methods, utilised to discard the remaining dietary molecules, also eliminated a significant proportion of endogenous AA. [less ▲]

The oxidant/antioxidant equilibrium of trained thoroughbred horses (n = 40) was assessed on three occasions during a period of three months under field conditions by blood antioxidant markers analysis, i.e. plasma ascorbic acid (AA), plasma antioxidant capacity of water-soluble components (ACW), whole blood (GSH) and oxidised (GSSG) glutathione, plasma alpha-tocopherol and beta-carotene, plasma antioxidant capacity of lipid-soluble components (ACL), red blood cell superoxide dismutase (SOD) and glutathione-peroxidase activity (GPx) and plasma trace-elements, i.e. selenium (Se), copper (Cu), zinc (Zn). A control group of ten horses receiving a placebo and an antioxidant group of 30 horses orally supplemented with an antioxidant mixture were randomly formed. An antioxidant imbalance was observed after three months in the control group, reflected by a significant decrease in GSH, SOD, GPx, Se (P < 0.05) and a significant increase in GSSG (P < 0.05). The antioxidant supplement prevented GPx and Se decrease and significantly increased ACW, alpha-tocopherol, beta-carotene and ACL (P < 0.05). Significant sex- or age-related differences were found for AA, ACW, alpha-tocopherol, SOD, GPx and Se, and there were significant correlations between ACW-AA, ACL-alpha-tocopherol, GPx-Se, CPK-Se, CPK-alpha-tocopherol and CPK-Cu. This field study has shown that trained thoroughbred horses undergo significant changes of several blood antioxidant markers and that oral antioxidant supplementation might partially counterbalance these changes by improving the hydrophilic, lipophilic and enzymatic antioxidant blood capacity.

The aim of this study was to investigate whether the osmolality of a glucose solution, ingested at the beginning of a prolonged exercise bout, affects exogenous glucose disposal. We investigated the hormonal and metabolic response to a 50-g glucose load dissolved in either 200 (protocol A), 400 (protocol B), or 600 (protocol C) ml of water and given orally 15 min after adaptation to exercise in five healthy male volunteers. Naturally labeled [13C]glucose was used to follow the conversion of the ingested glucose to expired-air CO2. Total carbohydrate oxidation (indirect calorimetry) was similar in the three protocols (A, 237 +/- 20; B, 258 +/- 17; C, 276 +/- 20 g/4 h), as was lipid oxidation (A, 128 +/- 4; B, 132 +/- 15; C, 124 +/- 12 g/4 h). Exogenous glucose oxidation rates were similar under the three experimental conditions, and the total amount of exogenous glucose utilized was slightly, but not significantly, increased with the more diluted solution (A, 42.6 +/- 4.4; B, 43.4 +/- 4.1; C, 48.7 +/- 7.2 g/4 h). The blood glucose response was similar in the three protocols. Thus, within the range investigated, the osmolality of the glucose solution ingested had no significant influence either on its oxidation (which was 86-98% of the load ingested) or on the utilization of endogenous carbohydrate, lipid, or protein stores.

The objective of this study was to evaluate the effects of ovariectomy (i) and ad libitum feeding (ii) on energy intake, body weight (BW), body composition, thyroid status, leptin and ghrelin plasma concentrations. Four young adult female Beagle dogs were fed a maintenance diet for 6 weeks prior to ovariectomy, then 6 months after. Food allowance was adjusted in order to maintain optimal BW. Then, a diet slightly higher in energy concentration was fed ad libitum for 4 months. The maintenance diet was then fed ad libitum for one additional month. The maintenance of optimal BW after ovariectomy required a significant decrease in energy allowance. No increase in fat mass was observed. Ghrelin concentration remained unchanged. During the first month of ad libitum feeding, plasma ghrelin concentration and energy intake increased, then they decreased. Mean BW, plasma leptin, thyrotropin (TSH), total triiodothyronine (TT3) and total thyroxine (TT4) concentrations significantly increased over the study. The BW increase was exclusively due to an increase in body fat. In conclusion, energy allowance should be strictly controlled in spayed female dogs. The results suggest that in dogs, thyroid hormones, leptin and ghrelin concentrations change in response to a positive energy balance in an attempt to limit weight gain. However, the significant weight gain shows that this goal was not achieved. [less ▲]

BACKGROUND: Once-daily injections of parathyroid hormone or its amino-terminal fragments increase bone formation and bone mass without causing hypercalcemia, but their effects on fractures are unknown. METHODS: We randomly assigned 1637 postmenopausal women with prior vertebral fractures to receive 20 or 40 microg of parathyroid hormone (1-34) or placebo, administered subcutaneously by the women daily. We obtained vertebral radiographs at base line and at the end of the study (median duration of observation, 21 months) and performed serial measurements of bone mass by dual-energy x-ray absorptiometry. RESULTS: New vertebral fractures occurred in 14 percent of the women in the placebo group and in 5 percent and 4 percent, respectively, of the women in the 20-microg and 40-microg parathyroid hormone groups; the respective relative risks of fracture in the 20-microg and 40-microg groups, as compared with the placebo group, were 0.35 and 0.31 (95 percent confidence intervals, 0.22 to 0.55 and 0.19 to 0.50). New nonvertebral fragility fractures occurred in 6 percent of the women in the placebo group and in 3 percent of those in each parathyroid hormone group (relative risk, 0.47 and 0.46, respectively [95 percent confidence intervals, 0.25 to 0.88 and 0.25 to 0.861). As compared with placebo, the 20-microg and 40-microg doses of parathyroid hormone increased bone mineral density by 9 and 13 more percentage points in the lumbar spine and by 3 and 6 more percentage points in the femoral neck; the 40-microg dose decreased bone mineral density at the shaft of the radius by 2 more percentage points. Both doses increased total-body bone mineral by 2 to 4 more percentage points than did placebo. Parathyroid hormone had only minor side effects (occasional nausea and headache). CONCLUSIONS: Treatment of postmenopausal osteoporosis with parathyroid hormone (1-34) decreases the risk of vertebral and nonvertebral fractures; increases vertebral, femoral, and total-body bone mineral density; and is well tolerated. The 40-microg dose increased bone mineral density more than the 20-microg dose but had similar effects on the risk of fracture and was more likely to have side effects. [less ▲]

Objectives: Postoperative peritoneal adhesions are frequent after abdominal surgery. Many preventive agents have been tried in animal models and in clinical trials, but up to now, there has been no definitive strategy to prevent their formation. In this study, the effectiveness of parecoxib (Dynastat®), a selective cyclooxygenase-2 inhibitor, in preventing experimental intra-abdominal adhesions in rats was studied. Methods: Thirty male rats who underwent a primary surgical procedure aiming at inducing peritoneal injury to produce intraabdominal adhesion, were randomized in three groups: (A) control group, no therapy; (B) intraperitoneal (IP) parecoxib group; (C) intramuscular (IM) parecoxib group. Ten days later, a xyphopubic midline incision was performed and the whole abdominal cavity was explored to score the peritoneal adhesions. Results: Twenty-three rats developed adhesions, 9 (100%) in group A, 7 (70%) in group B and 4 (40%) in group C (P=0.01). The extent and severity scores of adhesion were significantly lower in groups B and C than those in control group (p<0.001). Type of adhesions was measured at 2.25 ± 0.67 in group A, 1.20 ± 0.86 in group B and 0.82 ± 0.80 in group C. This was significantly different between group A and B (p<0.001), between A and C (p<0.001). But no significant difference was found between group B and C (p=0.17). Conclusions: In this study, we found a significant effect on parecoxib in the prevention of postoperative adhesions. But, without avoiding completely the formation of adhesion, parecoxib reduces significantly extent and severity of postoperative adhesions in rats treated with IP or IM parecoxib administration.

In developmental neuropsychology, information about the influence of educational variables on executive and memory development is limited. This is particularly surprising when considering the adult literature regarding the social and cultural effects on cognitive performances, which provide evidence that groups with higher levels of education achieve better on most neuropsychological tests (Ostrosky, Ardila, & Rosselli, 1999). The aim of this study was to analyze the relation between parents’ educational level and executive, attentional, memory and intellectual measures. Memory tasks (working and episodic memory), executive (inhibition and switching), attentional (alertness and selective attentional task) and intellectual tasks (verbal and non verbal subtests of WISC-III) were individually administered to 96 children divided according to 2 variables: age (6 and 10 years old) and parent’s educational level (University, High School and Elementary Education). Results showed an expected significant association between age and performance on all cognitive tasks. There was also a significant effect of parents’ educational level on most verbal tasks performed by children (including memory and verbal intellectual subtests) but also on various executive and attentional tasks (alertness, switching and inhibition tasks). Results confirmed that educational variables significantly influence children cognitive performances and not for only intelligence and verbal tasks, and emphasizes the need of further studies to specify the influence of education on the development of cognition.
