Lane-Departure Safety Countermeasures: Strategic Action Plan for the Iowa Department of Transportation, 2011

Lane departure crashes are the single largest category of fatal and major injury crashes in Iowa. The Iowa Department of Transportation (DOT) estimates that 60 percent of roadway-related fatal crashes are lane departures and that 39 percent of Iowa’s fatal crashes are single-vehicle run-off-road (SVROR) crashes. Addressing roadway departure was identified as one of the top eight program strategies for the Iowa DOT in their Comprehensive Highway Safety Plan (CHSP). The goal is to reduce lane departure crashes and their consequences through lane departure-related design standards and policies including paved shoulders, centerline and shoulder rumble strips, pavement markings, signs, and median barriers. Lane-Departure Safety Countermeasures: Strategic Action Plan for the Iowa Department of Transportation outlines roadway countermeasures that can be used to address lane departure crashes. This guidance report was prepared by the Institute for Transportation (InTrans) at Iowa State University for the Iowa DOT. The content reflects input from and multiple reviews by both a technical advisory committee and other knowledgeable individuals with the Iowa DOT.

Inhibition of voltage-gated Na(+) currents in sensory neurones by the sea anemone toxin APETx2.

BACKGROUND AND PURPOSE: APETx2, a toxin from the sea anemone Anthropleura elegantissima, inhibits acid-sensing ion channel 3 (ASIC3)-containing homo- and heterotrimeric channels with IC(50) values < 100 nM and 0.1-2 µM respectively. ASIC3 channels mediate acute acid-induced and inflammatory pain response and APETx2 has been used as a selective pharmacological tool in animal studies. Toxins from sea anemones also modulate voltage-gated Na(+) channel (Na(v) ) function. Here we tested the effects of APETx2 on Na(v) function in sensory neurones.¦EXPERIMENTAL APPROACH: Effects of APETx2 on Na(v) function were studied in rat dorsal root ganglion (DRG) neurones by whole-cell patch clamp.¦KEY RESULTS: APETx2 inhibited the tetrodotoxin (TTX)-resistant Na(v) 1.8 currents of DRG neurones (IC(50) , 2.6 µM). TTX-sensitive currents were less inhibited. The inhibition of Na(v) 1.8 currents was due to a rightward shift in the voltage dependence of activation and a reduction of the maximal macroscopic conductance. The inhibition of Na(v) 1.8 currents by APETx2 was confirmed with cloned channels expressed in Xenopus oocytes. In current-clamp experiments in DRG neurones, the number of action potentials induced by injection of a current ramp was reduced by APETx2.¦CONCLUSIONS AND IMPLICATIONS: APETx2 inhibited Na(v) 1.8 channels, in addition to ASIC3 channels, at concentrations used in in vivo studies. The limited specificity of this toxin should be taken into account when using APETx2 as a pharmacological tool. Its dual action will be an advantage for the use of APETx2 or its derivatives as analgesic drugs.

NR2A at CA1 synapses is obligatory for the susceptibility of hippocampal plasticity to sleep loss.

A loss in the necessary amount of sleep alters expression of genes and proteins implicated in brain plasticity, but key proteins that render neuronal circuits sensitive to sleep disturbance are unknown. We show that mild (4-6 h) sleep deprivation (SD) selectively augmented the number of NR2A subunits of NMDA receptors on postsynaptic densities of adult mouse CA1 synapses. The greater synaptic NR2A content facilitated induction of CA3-CA1 long-term depression in the theta frequency stimulation range and augmented the synaptic modification threshold. NR2A-knock-out mice maintained behavioral response to SD, including compensatory increase in post-deprivation resting time, but hippocampal synaptic plasticity was insensitive to sleep loss. After SD, the balance between synaptically activated and slowly recruited NMDA receptor pools during temporal summation was disrupted. Together, these results indicate that NR2A is obligatory for the consequences of sleep loss on hippocampal synaptic plasticity. These findings could advance pharmacological strategies aiming to sustain hippocampal function during sleep restriction.

Vers une gestion de la nature en termes d'action publique : analyse d'une dynamique d'appropriation des ressources végétales à Tobré, Nord Bénin

Cette étude se fonde sur des recherches ethnographiques menées autour de la mise en oeuvre d'une politique publique de gestion de la nature à Tobré, une région baatonu au Bénin. L'étude se place dans une dynamique d'appropriation des ressources naturelles en rapport avec l'entrée en jeu de multiples acteurs publics et privés dans l'arène locale de gestion de la nature. En effet, ces acteurs ont acquis ces dernières années de l'expérience et de l'efficacité à la faveur des changements institutionnels et politiques et s'incluent davantage dans le processus de décision au point de suppléer l'Etat dans les actions qui étaient ses prérogatives. L'étude met en lumière les rapports de conflits, de compétitions, de concurrence ou de compromis autour des enjeux sociaux, politiques et économiques de protection de la nature. Elle décrit et analyse les formes d'interactions entre les différents acteurs individuels, collectifs et institutionnels, afin de voir en quoi ces interactions participent du processus de mobilisation d'acteurs locaux et de confrontation de vision, qui finalement définit et oriente les politiques locales de protection de la nature. Pour atteindre cet objectif, l'étude mobilise des apports théoriques de plusieurs disciplines, notamment de la socio- anthropologie du développement, de l'histoire et de la sociologie politique. Elle repose également sur des données empiriques collectées à partir d'une combinaison d'outils techniques, des entretiens et des observations jusqu'au dépouillement de presse et des études de cas. Les principaux résultats montrent que les acteurs locaux, particulièrement les comités de gestion sont parvenus à inscrire la gestion des ressources naturelles dans l'espace public à travers les débats dans les médias, les forums, les marches de protestation, etc. De fait, ils ont été capables d'influer sur le processus de définition et de mise en oeuvre des politiques locales de protection de la nature et donc de reconfigurer l'arène locale de gestion des ressources naturelles. Ce qui amène l'Etat et ses services déconcentrés, en premier lieu les services des Eaux et Forêts et la mairie à pactiser avec ces différents comités, sans pour autant perdre de leur notoriété. Au contraire, ils participent de la gouvernance de l'ensemble des actions et permettent de mettre en place des formes de gestion négociée. - This is an ethnographic research on the implementation of a public policy for the management of natural resources in Tobre, a baatonu village in Benin. The study focuses on the dynamic of natural resources ownership in a context of multiple stakeholders in the public and private sectors. In recent years, these stakeholders have become more experienced and efficient as a result of several institutional and policy changes. The stakeholders are more involved in the decision making process to the point that they can complement the role of the State in natural resources management. This study highlights the conflicts, competition, or compromise associated with the social, political and economic constraints of nature conservation. The interactions between individual, collective and institutional stakeholders were analyzed, to understand their role in the process of mobilizing local stakeholders and confronting their visions. This process ultimately defines and guides local policies on the management of nature. To achieve this goal, this study combined theoretical approaches from developmental socio-anthropology, history and political sociology with empirical data collected using interviews, observations, newspapers analysis and case studies. The results show that local stakeholders, particularly the management committees, were successful at introducing the need for sustainable natural resource management in the mainstream public discourse through the media, forums, and demonstrations. They were able to influence the process of identifying and implementing local policies on nature conservancy. This has encouraged the State, through its forestry services, and the district mayors to collaborate with these committees in the shared governance of natural resources.

Peroxisome proliferator-activated receptor β/δ: a master regulator of metabolic pathways in skeletal muscle

Skeletal muscle is considered to be a major site of energy expenditure and thus is important in regulating events affecting metabolic disorders. Over the years, both in vitro and in vivo approaches have established the role of peroxisome proliferator-activated receptor-β/δ (PPARβ/δ) in fatty acid metabolism and energy expenditure in skeletal muscles. Pharmacological activation of PPARβ/δ by specific ligands regulates the expression of genes involved in lipid use, triglyceride hydrolysis, fatty acid oxidation, energy expenditure, and lipid efflux in muscles, in turn resulting in decreased body fat mass and enhanced insulin sensitivity. Both the lipid-lowering and the anti-diabetic effects exerted by the induction of PPARβ/δ result in the amelioration of symptoms of metabolic disorders. This review summarizes the action of PPARβ/δ activation in energy metabolism in skeletal muscles and also highlights the unexplored pathways in which it might have potential effects in the context of muscular disorders. Numerous preclinical studies have identified PPARβ/δ as a probable potential target for therapeutic interventions. Although PPARβ/δ agonists have not yet reached the market, several are presently being investigated in clinical trials.

International Union of Pharmacology. LXI. Peroxisome proliferator-activated receptors.

The three peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors of the nuclear hormone receptor superfamily. They share a high degree of structural homology with all members of the superfamily, particularly in the DNA-binding domain and ligand- and cofactor-binding domain. Many cellular and systemic roles have been attributed to these receptors, reaching far beyond the stimulation of peroxisome proliferation in rodents after which they were initially named. PPARs exhibit broad, isotype-specific tissue expression patterns. PPARalpha is expressed at high levels in organs with significant catabolism of fatty acids. PPARbeta/delta has the broadest expression pattern, and the levels of expression in certain tissues depend on the extent of cell proliferation and differentiation. PPARgamma is expressed as two isoforms, of which PPARgamma2 is found at high levels in the adipose tissues, whereas PPARgamma1 has a broader expression pattern. Transcriptional regulation by PPARs requires heterodimerization with the retinoid X receptor (RXR). When activated by a ligand, the dimer modulates transcription via binding to a specific DNA sequence element called a peroxisome proliferator response element (PPRE) in the promoter region of target genes. A wide variety of natural or synthetic compounds was identified as PPAR ligands. Among the synthetic ligands, the lipid-lowering drugs, fibrates, and the insulin sensitizers, thiazolidinediones, are PPARalpha and PPARgamma agonists, respectively, which underscores the important role of PPARs as therapeutic targets. Transcriptional control by PPAR/RXR heterodimers also requires interaction with coregulator complexes. Thus, selective action of PPARs in vivo results from the interplay at a given time point between expression levels of each of the three PPAR and RXR isotypes, affinity for a specific promoter PPRE, and ligand and cofactor availabilities.

Advances in the pharmacological treatment of gastro-oesophageal cancer.

Despite a sharp decline in the incidence of gastric cancer during the second half of the 20th century, this malignancy remains the second leading cause of cancer mortality in the world. The incidence and mortality rate of gastric cancer increase with age; at present, the median ages at diagnosis are 67 years for men and 72 years for women in the US. This article reviews and discusses current medical treatment options for both the general population and elderly gastric cancer patients. Management of localized gastric cancer has changed significantly over recent years. Adjuvant chemoradiation is not generally recommended outside the US. After decades of trials of adjuvant chemotherapy with inconclusive results, a significant survival benefit for perioperative combination chemotherapy - as compared with surgery alone - in patients with resectable or locally advanced gastro-oesophageal cancer was recently demonstrated in the UK MAGIC trial. A further large, randomized trial from Japan demonstrated a significant survival benefit for adjuvant chemotherapy with S-1 after D2 resection for gastric cancer. However, both trials are applicable only to the population in which the trials were conducted. Specific data on elderly patients are missing. For patients with metastatic disease, oral fluoropyrimidines, such as capecitabine, have been developed. In Asian patients, treatment with the oral fluoropyrimidine S-1 is safe and effective. Docetaxel, oxaliplatin and irinotecan have demonstrated activity against gastric cancer in appropriately designed, randomized, phase III trials and have increased the available treatment options significantly. In addition, according to preliminary data, trastuzumab in combination with chemotherapy has significantly improved activity when compared to chemotherapy alone in patients with human epidermal receptor (HER)-2-positive gastric and gastro-oesophageal cancers. Thus, therapeutic decisions in patients with advanced gastric cancer may be adapted to the molecular subtype and co-morbidities of the individual patient. Data from retrospective analyses suggest that oxaliplatin seems to be better tolerated than cisplatin in elderly patients.

Travail militant, action collective et rapports de genre

In that paper we propose a gendered approach to social movements and political activism, based on a critical review of the litterature in French and English. In social movements and militantism studies, gender lines of division are most of the time ignored. Social movements are perceived as being « gender neutral ». However, that dimension is a determinant factor of collective action at the macro level of political opportunities and contexts, at the meso level of organisations and their modes of functionning, at the micro level of the logics of individual commitment and the division of militant labor.

Ectodysplasin A (EDA) - EDA receptor signalling and its pharmacological modulation.

The TNF family ligand ectodysplasin A (EDA) regulates the induction, morphogenesis and/or maintenance of skin-derived structures such as teeth, hair, sweat glands and several other glands. Deficiencies in the EDA - EDA receptor (EDAR) signalling pathway cause hypohidrotic ectodermal dysplasia (HED). This syndrome is characterized by the absence or malformation of several skin-derived appendages resulting in hypotrychosis, hypodontia, heat-intolerance, dry skin and dry eyes, susceptibility to airways infections and crusting of various secretions. The EDA-EDAR system is an important effector of canonical Wnt signalling in developing skin appendages. It functions by stimulating NF-κB-mediated transcription of effectors or inhibitors of the Wnt, Sonic hedgehog (SHH), fibroblast growth factor (FGF) and transforming growth factor beta (TGFβ) pathways that regulate interactions within or between epithelial and mesenchymal cells and tissues. In animal models of Eda-deficiency, soluble EDAR agonists can precisely correct clinically relevant symptoms with low side effects even at high agonist doses, indicating that efficient negative feedback signals occur in treated tissues. Hijacking of the placental antibody transport system can help deliver active molecules to developing foetuses in a timely manner. EDAR agonists may serve to treat certain forms of ectodermal dysplasia.
