The European transport policy has focused on sustainable transport solutions, among which intermodal transport is a key player. However, its efficiency is strongly dependent on the location of the container terminals. In this paper, a set of estimated potential locations is used as input for an iterative procedure based on the p-hub median problem that takes the variation in trans-shipment costs according to the number of trans-shipped containers into account. The final results are the optimal locations for European transfer terminals embedded in a hub-and-spoke network. [less ▲]

This article focuses on the first novel by Nigerian writer Chimamanda Ngozi Adichie, Purple Hibiscus (2003). It examines how religious prejudice is encoded in the account of the book’s autodiegetic narrator, a fifteen-year-old girl whose father is a violent, extremist Igbo Catholic. Based on a close reading of the text, the essay argues that an analysis of the novel’s use of speech and thought presentation may contribute to the assessment of the main character’s evolving ideological stance. It is suggested that the resulting appraisal of the narrator’s development provides key insights into the interpretation of the book. [less ▲]

STUDY OBJECTIVES: The ultradian NREM-REM sleep cycle and the circadian modulation of REM sleep sum to generate dreaming. Here we investigated age-related changes in dream recall, number of dreams, and emotional domain characteristics of dreaming during both NREM and REM sleep. DESIGN: Analysis of dream recall and sleep EEG (NREM/REM sleep) during a 40-h multiple nap protocol (150 min of wakefulness and 75 min of sleep) under constant routine conditions. SETTING: Centre for Chronobiology, Psychiatric Hospital of the University of Basel, Basel, Switzerland. PARTICIPANTS: Seventeen young (20-31 years) and 15 older (57-74 years) healthy volunteers INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: Dream recall and number of dreams varied significantly across the circadian cycle and between age groups, with older subjects exhibiting fewer dreams (P < 0.05), particularly after naps scheduled during the biological day, closely associated with the circadian rhythm of REM sleep. No significant age differences were observed for the emotional domain of dream content. CONCLUSIONS: Since aging was associated with attenuated amplitude in the circadian modulation of REM sleep, our data suggest that the age-related decrease in dream recall can result from an attenuated circadian modulation of REM sleep.

Oculofaciocardiodental (OFCD) and Lenz microphthalmia syndromes form part of a spectrum of X-linked microphthalmia disorders characterized by ocular, dental, cardiac and skeletal anomalies and mental retardation. The two syndromes are allelic, caused by mutations in the BCL-6 corepressor gene (BCOR). To extend the series of phenotypes associated with pathogenic mutations in BCOR, we sequenced the BCOR gene in patients with (1) OFCD syndrome, (2) putative X-linked ('Lenz') microphthalmia syndrome, (3) isolated ocular defects and (4) laterality phenotypes. We present a new cohort of females with OFCD syndrome and null mutations in BCOR, supporting the hypothesis that BCOR is the sole molecular cause of this syndrome. We identify for the first time mosaic BCOR mutations in two females with OFCD syndrome and one apparently asymptomatic female. We present a female diagnosed with isolated ocular defects and identify minor features of OFCD syndrome, suggesting that OFCD syndrome may be mild and underdiagnosed. We have sequenced a cohort of males diagnosed with putative X-linked microphthalmia and found a mutation, p.P85L, in a single case, suggesting that BCOR mutations are not a major cause of X-linked microphthalmia in males. The absence of BCOR mutations in a panel of patients with non-specific laterality defects suggests that mutations in BCOR are not a major cause of isolated heart and laterality defects. Phenotypic analysis of OFCD and Lenz microphthalmia syndromes shows that in addition to the standard diagnostic criteria of congenital cataract, microphthalmia and radiculomegaly, patients should be examined for skeletal defects, particularly radioulnar synostosis, and cardiac/laterality defects.

Introduction The first part of the study devoted to guided tissue regenerative membranes was focused on a better understanding of the physicochemical and mechanical properties of commercial materials. The second objective of our study was to develop an in vitro device able to measure the long-term barrier effect of resorbable membranes. After the development of this new device, experiments were realized to characterize the long-term behaviour of commercially membranes with human gingival fibroblasts (HGF). Materials and methods The use of human gingival fibroblastic cells was chosen to get closer to biological conditions. Some gingival explants were removed in young and non-smoking healthy patients. From these explants, fibroblastic cells were isolated and cultivated. These cells will be able to be used between the third and the sixth passage. Resorbable membranes were chosen because they don’t require a second surgical operation. There are made of polyesters or collagen. A system based on inserts was developed in order to follow the degradation of membranes and the migration of cells across the material. The membrane was cut into 8 mm diameter punches and set in the bottom of the system. Once the whole was put together, it is laced into a 12 wells plate culture. First, the plates were put in an incubator at 37°C, during times ranging from 24 hours to several months. The barrier effect was then measured to reflect the gradual increase of permeability of each membrane. For this purpose, HGF were seeded on the different samples. The top of the bottle and the bottom of the well were then filled with culture medium. Non degradable synthetic Bioflex membranes were chosen as control samples which don't let pass cells (porosity : 0,4 µm). After 48 hours of incubation in the presence of cells, pictures of cells on membranes and in the bottom of wells were taken with an optic microscope. Viability tests (MTS) were then realized on membranes to evaluate cells proliferation and in the bottom of wells to measure barrier effect. Finally, the morphology of cells on selected membranes was characterized by Scanning Electron Microscopy. Conclusion Proliferation results correspond to data published by several authors. Furthermore, the barrier effect times found in the present study are similar to barrier effect times demonstrated in in vivo studies and announced by manufacturers. In conclusion, the finalized system is adapted to the analysis of long-term barrier effect of commercial GTR membranes. This system will be tested with synthetic bioresorbable membranes made of copolymers. [less ▲]

Obesity plays a key role in the pathophysiology of type 2 diabetes (T2DM), and weight loss is a major objective, although difficult to achieve with medical treatments. Bariatric surgery has proven its efficacy in obtaining marked and sustained weight loss, and is also associated with a significant improvement in glucose control and even diabetes remission. Roux-en-Y gastric bypass appears to be more effective in diabetic patients than the restrictive gastroplasty procedure. This may be explained not only by greater weight reduction, but also by specific hormonal changes. Indeed, increased levels of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) may lead to improved beta-cell function and insulin secretion as well as reduced insulin resistance associated with weight loss. The presence of T2DM in obese individuals is a further argument to propose bariatric surgery, and even more so when diabetes is difficult to manage by medical means and other weight-related complications may occur. Bariatric surgery is associated with a better cardiovascular prognosis and reduced mortality, even though acute and long-term complications are present. The observation that surgical rerouting of nutrients triggers changes in the release of incretin hormones that, in turn, ameliorate the diabetic state in the absence of weight loss has led to the recent development of innovative surgical procedures. Thus, bariatric surgery may be said to be progressing towards so-called 'metabolic surgery', which merits further evaluation in patients with T2DM within a multidisciplinary approach that involves both surgeons and endocrinologists.

Artificial olfaction system (the so-called electronic nose) is a very promising tool to monitor the malodour in the field. Usual odour measurement techniques use human olfaction or analytical techniques. The first category represents the real odour perception but is not applicable to measure in continuous bad odours in the field. The second class of techniques gives the composition of the mixture but not the global information representative of the odour perception. The e-nose has the potentialities to combine “the odour perception” and the “monitoring in the field”. However to be able to reach this goal, the signal processing has to be adapted to work in complex environment. We have more than teen years experiments in the measure of environmental malodours in the field and the paper presents the minimal requirements that we consider essential for artificial olfaction system to become successful for this application.

Insulin glargine is widely used as basal insulin in the treatment of type 1 and type 2 diabetes mellitus. However, this insulin analogue has been recently suspected to be associated with an increased risk of cancer, especially breast cancer, in patients with type 2 diabetes. The present article aims at briefly presenting the state of the art based upon currently available data. We will first summarize the observations reported in recent publications, then we will present a critical analysis of these in fact non-conclusive findings, and finally we will conclude with some practical recommendations.

A QTL detection experiment was performed in French dairy cattle to search for QTL related to male fertility. Ten families, involving a total of 515 bulls, were phenotyped for ejaculated volume and sperm concentration, number of spermatozoa, motility, velocity, percentage of motile spermatozoa after thawing and abnormal spermatozoa. A set of 148 microsatellite markers were used to realize a genome scan. First, genetic parameters were estimated for all traits. Semen production traits were found to have moderate heritabilities (from 0.15 to 0.30) while some of the semen quality traits such as motility had high heritabilities (close to 0.60). Genetic correlations among traits showed negative relationships between volume and concentration and between volume and most quality traits such as motility or abnormal sperm while correlations between concentration and these traits were rather favourable. Percentages of abnormal sperm were negatively related to quality traits, especially with motility and velocity of spermatozoa. Three QTL related to abnormal sperm frequencies were significant at p < 0.01. In total, 11 QTL (p < 0.05) were detected. However, the number of QTL detected was within the range of expected false positives. Because of the lack of power to find QTL in this design further analyses are required to confirm these QTL.

The purpose of this study was to compare pure concentric and eccentric isokinetic training with respect to their possible specificity in the progression of strength of the knee flexor and extensor muscles. Subjects were divided into 2 groups (eccentric or concentric training) and performed a specific training of dominant leg. Before and after the training session, isokinetic performances of trained leg and non-trained leg (cross-education) were evaluated. We observed a greater increase of muscle performances after eccentric training. A cross-education effect was measured exclusively after eccentric training session. We showed an increase of maximal eccentric performances after the pure concentric training. No significant progression of maximal concentric performance was measured after eccentric training.

We present the analysis of FUV (1150-1750 Å) limb dayglow spectra of Titan’s atmosphere obtained on 13 December 2004 at 5 Å resolution by the Ultraviolet Imaging Spectrograph (UVIS) onboard Cassini. The fit to the data show that Titan’s airglow consists of four principal emissions: 1) the N2 Lyman-Birge-Hopfield (LBH) band system, which peaks in intensity at 1150 +/- 50 km, 2) N I multiplets peaking at 1050km +/- 50 km, 3) sunlight reflected by N2 between 0 and 300 km and 4) H Ly alpha which grows in intensity with increasing altitude. Comparisons with limb spectra obtained by the Voyager 1 Ultraviolet spectrometer (V1/UVS) show that the vertically integrated brightness are larger for V1/UVS than for UVIS by a factor of 3, consistent with the XUV solar flux ratio at Titan at the time of these observations. The N2 LBH and N I profiles obtained from the regression to the Titan data are compared to models obtained by the Atmospheric Ultraviolet Radiance Integrated Code (AURIC), adapted from Earth’s atmosphere to Titan’s.
