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.

Reduction of ARNT in myeloid cells causes immune suppression and delayed wound healing.

Aryl hydrocarbon receptor nuclear translocator (ARNT) is a transcription factor that binds to partners to mediate responses to environmental signals. To investigate its role in the innate immune system, floxed ARNT mice were bred with lysozyme M-Cre recombinase animals to generate lysozyme M-ARNT (LAR) mice with reduced ARNT expression. Myeloid cells of LAR mice had altered mRNA expression and delayed wound healing. Interestingly, when the animals were rendered diabetic, the difference in wound healing between the LAR mice and their littermate controls was no longer present, suggesting that decreased myeloid cell ARNT function may be an important factor in impaired wound healing in diabetes. Deferoxamine (DFO) improves wound healing by increasing hypoxia-inducible factors, which require ARNT for function. DFO was not effective in wounds of LAR mice, again suggesting that myeloid cells are important for normal wound healing and for the full benefit of DFO. These findings suggest that myeloid ARNT is important for immune function and wound healing. Increasing ARNT and, more specifically, myeloid ARNT may be a therapeutic strategy to improve wound healing.

Modulatory effects of acid-sensing ion channels on action potential generation in hippocampal neurons.

Extracellular acidification has been shown to generate action potentials (APs) in several types of neurons. In this study, we investigated the role of acid-sensing ion channels (ASICs) in acid-induced AP generation in brain neurons. ASICs are neuronal Na(+) channels that belong to the epithelial Na(+) channel/degenerin family and are transiently activated by a rapid drop in extracellular pH. We compared the pharmacological and biophysical properties of acid-induced AP generation with those of ASIC currents in cultured hippocampal neurons. Our results show that acid-induced AP generation in these neurons is essentially due to ASIC activation. We demonstrate for the first time that the probability of inducing APs correlates with current entry through ASICs. We also show that ASIC activation in combination with other excitatory stimuli can either facilitate AP generation or inhibit AP bursts, depending on the conditions. ASIC-mediated generation and modulation of APs can be induced by extracellular pH changes from 7.4 to slightly <7. Such local extracellular pH values may be reached by pH fluctuations due to normal neuronal activity. Furthermore, in the plasma membrane, ASICs are localized in close proximity to voltage-gated Na(+) and K(+) channels, providing the conditions necessary for the transduction of local pH changes into electrical signals.

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.

Systematic review of delayed postoperative hemorrhage after pancreatic resection

Objective:This review assesses the presentation,management, and outcome of delayed postpancreatectomy hemorrhage (PPH) and suggests a novel algorithm as possible standard of care.Methods: An electronic search of Medline and Embase databases from January 1990 to February 2010 was undertaken. A random-effect meta-analysis for success rate and mortality of laparotomy vs. interventional radiology after delayed PPH was performed.Results: Fifteen studies including 248 patients with delayed PPH were included. Its incidence was 3?3%. A sentinel bleed heralding a delayed PPH was observed in 45% of cases. Pancreatic leaks or intraabdominal abscesses were found in 62%. Interventional radiology was attempted in 41%, and laparotomy was undertaken in 49%. On meta-analysis comparing laparotomy vs. interventional radiology, no significant difference could be observed in term of complete hemostasis (76% vs. 80%; P = 0?35). A statistically significant difference favored interventional radiology vs. laparotomy in term of mortality (22% vs. 47%; P = 0?02).Conclusion: Proper and early management of postoperative complications, such as pancreatic leak and intraabdominal abscess, minimizes the risk of delayed PPH. Sentinel bleeding needs to be thoroughly investigated. If a pseudoaneurysm is detected, it has to be treated by interventional angiography, in order to prevent a further delayed PPH. Early angiography and embolization or stenting is safe and should be the procedure of choice. Surgery remains a therapeutic option if no interventional radiology is available, or patients cannot be resuscitated for an interventional treatment.

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.

Time-related action of Lactobacillus plantarum in the bacterial microbiota of shrimp digestive tract and its action as immunostimulant

The objective of this work was to assess the time-related action of probiotic Lactobacillus plantarum in the bacterial microbiota of the digestive tract of Litopenaeus vannamei, and the relation of total haemocyte count and serum phenol oxidase activity of shrimp challenged with Vibrio harveyi. Shrimps were fed with a probiotic-supplemented diet, for eight days, then shifted to a commercial diet. Shrimps fed only with the commercial diet served as control. Evaluations were made on the 8th day of experiment and repeated two, four, six and eight days later. Total lactic bacteria in the digestive tract was higher until the 4th day of evaluation in the probiotic-supplemented group. Vibrio spp. counts were higher in the control at days zero and two. Until the 4th day of evaluation, the total haemocyte counts in shrimps after challenge with V. harveyi were higher in probiotic-supplemented group than in control group. Significant difference was not observed in phenol oxidase activity. On the 6th day after shifting from supplemented to control diet, all parameters were equal in both groups, suggesting that the time-related action of L. plantarum in shrimp is short.

Type I IFN controls chikungunya virus via its action on nonhematopoietic cells.

Chikungunya virus (CHIKV) is the causative agent of an outbreak that began in La Réunion in 2005 and remains a major public health concern in India, Southeast Asia, and southern Europe. CHIKV is transmitted to humans by mosquitoes and the associated disease is characterized by fever, myalgia, arthralgia, and rash. As viral load in infected patients declines before the appearance of neutralizing antibodies, we studied the role of type I interferon (IFN) in CHIKV pathogenesis. Based on human studies and mouse experimentation, we show that CHIKV does not directly stimulate type I IFN production in immune cells. Instead, infected nonhematopoietic cells sense viral RNA in a Cardif-dependent manner and participate in the control of infection through their production of type I IFNs. Although the Cardif signaling pathway contributes to the immune response, we also find evidence for a MyD88-dependent sensor that is critical for preventing viral dissemination. Moreover, we demonstrate that IFN-alpha/beta receptor (IFNAR) expression is required in the periphery but not on immune cells, as IFNAR(-/-)-->WT bone marrow chimeras are capable of clearing the infection, whereas WT-->IFNAR(-/-) chimeras succumb. This study defines an essential role for type I IFN, produced via cooperation between multiple host sensors and acting directly on nonhematopoietic cells, in the control of CHIKV.
