The European mink (Mustela lutreola) is one of the most threatened carnivores in Europe, with fragmented populations in Belarus. Russia and Romania, as well in south-western France and northern Spain. Many populations have become extinct recently, or are declining. We investigated mitochondrial DNA variation, using the complete D-loop region, and concentrating oil the west European population. The aim was two-fold: to use the genetic information to advise on the conservation of European mink, and to begin to understand their history through the Pleistocene. Captive breeding and re-introduction programmes are underway, so it is particularly vital to know whether the West European population should be treated separately. We find that European mink probably colonised from a single refugium after the last glaciation. West European populations may be fixed for a single haplotype. also suggesting a common origin. Despite this evidence for gene flow, following the precautionary principle we suggest that mink from the three geographically separate populations (Romania, Eastern and Western Europe) should be managed separately, for the moment.

The objective of this study was to evaluate whether introducing the condensed wheat distillers soluble ProtiWanze® (PW) in diets of beef cattle has an impact on feeding costs, health and production of the animals. PW by-product from a Belgian bio-ethanol plant which utilized only wheat without bran, is an acid (pH=4) liquid feed rich in energy (VEM= 1130) and protein (TP= 282 mg/kg DM). PW supplementation from 9 to 13% on DM basis has been tested in 4 suckler cows’ farms for 4 months in 2011 and 2012. In 2011, 2 BB (H1 and H3) and 1 Blonde d’Aquitaine (H2: 23 cows) herds were evaluated and in 2012, the Blonde d’Aquitaine herd was replaced by a third BBB herd (H4: 42 cows). Every month, animals’ health and production were checked by the mean of Body Condition Score, Ruminal Fill, Fecal Consistency, Undigested Fraction and Locomotion Scores determination, as described by Zaaier et al.(2001) and Sprecher et al.(1997). Ruminal fluid was sampled by a stomach tube (Ruminator®) on 5 cows for pH, redox potential (Methylene blue test) and protozoa assessment (optical microscopy). Reproduction performances of this 2 year’s-period were analyzed. Price of a diet containing the same amount of proteins brought by a mixture of 1/3 soybean and 2/3 canola meal was calculated to verify whether introducing PW reduced feeding costs. Whatever the concentration of PW used, no adverse effect has been observed concerning reproduction, production performance, ruminal pH. Feeding costs were reduced by 0.08 €/cow/day in 2011 and by 0.02 €/cow/day in 2012. This lower spared amount in 2012 is the consequence of the reduction in PW protein concentration while its price increased. Anyway, comparison has to take into account the energy brought by this CDS as it has been suggested by Petersen’s equation, which compares CDS price with soybean meal but also with maize price. Further argument to be considered, especially in BB, is the high PW palatability, its low ruminal filling value and better roughage digestion. [less ▲]Detailed reference viewed: 21 (4 ULg)

The objective of this study was to evaluate whether introducing the condensed distillers soluble (CDS) ProtiWanze® (PW) in beef cattle diets has an impact on feeding costs, health and production of the animals. PW, a by-product derived from a Belgian bio-ethanol plant which utilizes only branless wheat, is an acid (pH=4) liquid feed rich in energy (VEM= 1130) and protein (TP= 282 mg/kg DM). PW supplementation from 9 to 13% on DM basis was tested in 4 suckler cattle farms for 4 months in 2011 and 2012: In 2011, 2 Belgian Blue (BB) (H1 and H3) and one Blonde d’Aquitaine (H2) herds were evaluated and in 2012, H2 was replaced by a third BB herd (H4). Every month, the animals’ health and production were checked by means of Body Condition Scoring (BCS), Ruminal Fill (RF), Fecal Consistency (FC), Undigested Fraction (UF) and Locomotion Scores (LS). Ruminal fluid was collected with a stomach tube (Ruminator®) on 5 cows for pH, redox potential (Methylene blue test) and protozoa assessment (optical microscopy). Reproduction performances during these 2 years were analyzed. The price of a diet containing the same amount of proteins brought by a mixture of 1/3 soybean and 2/3 canola meal was calculated to verify whether introducing PW reduced feeding costs.

Previous studies (Lum et al., 2009; Tomblin et al., 2007; Ullman & Pierpont, 2005) have suggested that difficulties in the procedural learning system could contribute, in part, to the language difficulties observed in children with SLI. However, we have recently shown, with an adapted serial reaction time (SRT) task, that children with SLI are able to learn implicitly non-linguistic regularities (Gabriel et al., submitted). In this research, we wanted to determine whether children with SLI are able to learn an 8-elements probabilistic sequence into which irregularities are inserted. Assessing probabilistic sequence learning in children with SLI should help us to better circumscribe the language difficulties of these children [less ▲]Detailed reference viewed: 177 (14 ULg)

The study of procedural learning abilities in children with Specific Language Impairment (Procedural Deficit Hypothesis, PDH; Ullman & Pierpont, 2005) remains a relatively unexplored field of research. Since most evidence comes from studies using tasks which involve learning of sequenced patterns, research using other procedural learning paradigms (like motor adaptation tasks) is needed to further evaluate the PDH in children with Specific Language Impairment (SLI). Therefore, in this study, we examined the ability of children with and without SLI to learn, consolidate and generalize a mirror-tracing task, a paradigm that does not involve sequence learning and had never been used in SLI. Children with SLI and typical developing (TD) matched children participated in the study. Children with SLI were included if they scored below -1.25 SD of the expected normative performance in at least 2 language areas. Both groups had to trace ten 5-pointed stars seen only in mirror-reversed view in two learning sessions separated by a one-week delay. The transfer phase consisted in tracing a new figure. The time required to complete the tracing, and the number of errors committed were recorded. Full results will be presented and discussed during the presentation of the paper.

Introduction Spatial neglect is a multicomponent syndrome characterized by an inability to orient or to respond to stimuli arising in the hemispace contralateral to a brain lesion. According to many authors, spatial neglect can be explained by an attentional deficit, and more specifically by a lateral attentional bias towards the right (magnetic attraction) and/or difficulties in disengaging attention from items to the right side. However, attentional theories are not sufficient to explain some behaviors such as revisiting and perseverations. Recently, it has been suggested that revisiting and perseveration behaviors in visual search tasks shown in parietal neglect could be related to impairments in visuo-spatial working memory (Husain et al., 2001; Malhotra et al., 2005; Malhotra, Mannan, Driver, & Husain, 2004). This hypothesis is supported by studies (1) in which a contrast is made between cancellation tasks with and without visual control, the absence of visual feedback increasing left neglect (omissions) and repeated cancellations (perseverations) towards the ipsilesional space, and (2) in which the Corsi test is administrated in a vertical way. However, Ronchi et al. (2009) did not confirm the link between impairments in spatial short-term memory and perseverations. Indeed, these authors found no correlation between perseverations in star cancellation and spatial memory performance in the Corsi test. Nevertheless, they did not use a condition without visual feedback, which is considered as involving more spatial short-term memory than a condition with visual feedback. This methodological choice could explain the lack of relationship between short-term memory and perseverations in the Ronchi et al.’s study. The purpose of our study was to test the hypothesis of a spatial short-term memory deficit being an explanatory factor of perseverations in unilateral neglect. Methods We assessed twenty right-damaged patients suffering from left neglect. Neglect signs were evaluated with the Batterie d’Evaluation de la Négligence (BEN) (Azouvi et al., 2002). Twenty healthy older participants matched for age and sociocultural level served as controls. In order to explore the relationship between perseverations and spatial short-term memory, two different tasks were administrated: a computerized version of the Corsi test and a cancellation task. All tests were computerized and presented on a touchscreen. The subject’s spatial span corresponded to the longest sequence in which at least three out of four sequences were correctly reproduced. The cancellation task consisted of 32 “O” presented in two conditions: with (visible) and without (invisible) visual feedback. Patients were instructed to cancel out all targets only once. The number of omissions and perseverations was calculated for each participant in both conditions. Results Control participants performed better than neglect patients in the Corsi test; eleven neglect patients showed a deficit in spatial short-term memory. In the cancellation tasks, Wilcoxon matched-pairs signed ranks tests highlighted that perseverations and omissions were greater in the invisible condition for each group. In this condition, neglect patients made more omissions and perseverations (all ps <.05) than control subjects, while in the visible condition there was only a significant difference for the omissions. However, spatial short-term memory did not explain perseverations in invisible condition (R² = .17, F(1,18) = 3.66, p = .07). Discussion These findings suggest that a spatial short-term memory deficit cannot be considered as an explanatory factor for the perseveration behavior in unilateral neglect. Moreover, perseverations and omissions were greater in the invisible condition than in the visible one; therefore, the hypothesis of the magnetic attraction is not confirmed either. In the neglect patients’ group, the visual feedback decreases, and even eliminates the neglect symptoms (omissions and perseverations) compared to the invisible condition. In other words, the presence of visual feedback can help patients to explore their visual environment. We propose that, in the invisible condition, difficulties to plan a visual search could exacerbate both omissions and perseverations, leading to recursive search towards the right side of the space and thus promote failure to explore left space. However, further investigations will be necessary to confirm this hypothesis. [less ▲]Detailed reference viewed: 71 (14 ULg)
Is there a role for alpha-glucosidase inhibitors in the prevention of type 2 diabetes mellitus?

Type 2 diabetes mellitus is a major health problem associated with excess morbidity and mortality. As the prevalence of this metabolic disorder is rapidly increasing and current treatment fails to stabilise the disease in most patients, prevention should be considered as a key objective in the near future. People who develop type 2 diabetes pass through a phase of impaired glucose tolerance (IGT). Defects in the action and/or secretion of insulin are the two major abnormalities leading to development of glucose intolerance. Any intervention in the impaired glucose tolerance phase that reduces resistance to insulin or protects the beta-cells, or both, should prevent or delay progression to diabetes.Acarbose, miglitol and voglibose act by competitively inhibiting the alpha-glucosidases, a group of key intestinal enzymes involved in the digestion of carbohydrates. They decrease both postprandial hyperglycaemia and hyperinsulinaemia, and thereby may improve sensitivity to insulin and release the stress on beta-cells. These compounds do not induce hypoglycaemia and have a good safety profile, although gastrointestinal adverse effects may limit long-term compliance to therapy.The recent placebo-controlled prospective STOP-noninsulin-dependent diabetes mellitus (STOP-NIDDM) trial demonstrated that acarbose 100mg three times daily reduces the risk of developing type 2 diabetes in patients with IGT (relative risk reduction of 25% after a mean follow-up of 3.3 years). The 6-year Early Diabetes Intervention Trial (EDIT), comparing the effect of acarbose 50mg three times daily to that of metformin, showed a trend to a positive effect of acarbose compared with placebo, in a mid-term 3-year analysis, which should be confirmed in the final analysis.To our knowledge, no such prevention intervention trials have been or are currently being performed with miglitol or voglibose. In conclusion, because of its absence of toxicity and its particular mechanism of action on gastrointestinal tract and indirect consequences on both insulin action and beta-cell function, acarbose may be used to prevent type 2 diabetes. If the ongoing EDIT trial confirms the positive results of the recent STOP-NIDDM trial, acarbose could be used, either as an alternative or in addition to changes in lifestyle, to delay development of diabetes in patients with IGT. However, the best dosage of acarbose for this specific indication remains to be specified, especially when all three important parameters, efficacy, tolerance and cost, are taken into consideration.
