Evaluating Community Partnerships Addressing Community Resilience in Los Angeles, California

Community resilience has grown in importance in national disaster response and recovery efforts. However, measurement of community resilience, particularly the content and quality of relationships aimed at improving resilience, is lacking. To address this gap, we used a social network survey to measure the number, type, and quality of relationships among organizations participating in 16 coalitions brought together to address community resilience in the Los Angeles Community Disaster Resilience project. These coalitions were randomized to one of two approaches (community resilience or preparedness). Resilience coalitions received training and support to develop these partnerships and implement new activities. Both coalition types received expert facilitation by a public health nurse or community educator. We also measured the activities each coalition engaged in and the extent to which partners participated in these activities at two time points. We found that the community resilience coalitions were initially larger and had lower trust among members than the preparedness communities. Over time, these trust differences dissipated. While both coalitions grew, the resilience community coalitions maintained their size difference throughout the project. We also found differences in the types of activities implemented by the resilience communities; these differences were directly related to the trainings provided. This information is useful to organizations seeking guidance on expanding the network of community-based organizations that participate in community resilience activities.
Central action of adrenomedullin to prevent ethanolinduced gastric injury through vagal pathways in rats.

Adrenomedullin (AM), belongs to the calcitonin gene-related peptide (CGRP) family and interacts with AM and CGRP1 receptors. Specific AM receptors and immunoreactivity are present in the rat brain. The effect of intracisternal injection of rat AM on ethanol-induced gastric lesions was studied in conscious Wistar rats. The peptide was injected intracisternally or intravenously under short anesthesia 20 min before intragastric injection of 70% ethanol. Corpus lesions were determined 1 h after ethanol. Intracisternal AM (75, 150, and 300 pmol) dose-dependently inhibited ethanol-induced gastric lesions by 40-72% and rat α-CGRP (150 pmol ic) by 76%. Intravenous AM (300 pmol) had no effect. The CGRP1 receptor antagonist CGRP-(8-37) (9.6-19.2 nmol ic) dose-dependently inhibited the protective effect of intracisternal α-CGRP but not that of AM. Subdiaphragmatic vagotomy and peripheral injection of atropine, indomethacin, or N G-nitro-l-arginine methyl ester (l-NAME) prevented AM protective action. l-Arginine but not d-arginine blockedl-NAME action. These data suggest that both AM and CGRP act in the brain to prevent ethanol-induced gastric lesions through interaction with their specific receptors. AM action may involve vagal cholinergic-dependent modulation of prostaglandins and nitric oxide protective mechanisms.
Graphene and graphene oxide as new lubricants in industrial applications

This master thesis report evaluatesthe lubricating effect of graphene (G)and graphene oxide (GO). Thesematerials have been added, in particlecondition, in Ag-based slidingcontacts and lubricating greases. Thework focuses on the tribologicalevaluation of these materials,especially friction, wear and contactresistance analyses. The friction andwear behaviors of Ag-based contactscontaining of a wide concentrationrange of graphene and graphene oxideare tested against pure silver using atest load of 2 and 10 N at a constantspeed of 5 cm/s. It was revealed thatsmall amounts of G and GO are able tosignificantly reduce the frictioncoefficient and wear rate. Contactresistance measurements revealed thatresults similar to pure Ag can beachieved with G content up to 10vol%. Possible mechanisms, which maycontribute to this tribologicalbehavior are the Ag-C interactions andthe lubricating nature of graphene.Friction tests with G and GOcontaining lubricating greases showinconsistent results, and both greasesand corresponding test methods forevaluation require furtheroptimization. The overall, promising,tribological behavior of G and GOholds for the implementation invarious industrial applications. Thereis no doubt that these kinds ofmaterials can play an important rolein ABBs future work. This masterthesis report shows yet anotherapplication area for theseextraordinary materials.
Parallel Loss of Myeloid and Plasmacytoid Dendritic Cells from Blood and Lymphoid Tissue in Simian AIDS1

The loss of myeloid (mDC) and plasmacytoid dendritic cells (pDC) from the blood of HIV-infected individuals is associated with progressive disease. It has been proposed that DC loss is due to increased recruitment to lymph nodes, although this has not been directly tested. Similarly as in HIV-infected humans, we found that lineage-negative (Lin−) HLA-DR+CD11c+CD123− mDC and Lin−HLA-DR+CD11c−CD123+ pDC were lost from the blood of SIV-infected rhesus macaques with AIDS. In the peripheral lymph nodes of SIV-naive monkeys the majority of mDC were mature cells derived from skin that expressed high levels of HLA-DR, CD83, costimulatory molecules, and the Langerhans cell marker CD1a, whereas pDC expressed low levels of HLA-DR and CD40 and lacked costimulatory molecules, similar to pDC in blood. Surprisingly, both DC subsets were depleted from peripheral and mesenteric lymph nodes and spleens in monkeys with AIDS, although the activation status of the remaining DC subsets was similar to that of DC in health. In peripheral and mesenteric lymph nodes from animals with AIDS there was an accumulation of Lin−HLA-DRmoderateCD11c−CD123− cells that resembled monocytoid cells but failed to acquire a DC phenotype upon culture, suggesting they were not DC precursors. mDC and pDC from the lymphoid tissues of monkeys with AIDS were prone to spontaneous death in culture, indicating that apoptosis may be a mechanism for their loss in disease. These findings demonstrate that DC are lost from rather than recruited to lymphoid tissue in advanced SIV infection, suggesting that systemic DC depletion plays a direct role in the pathophysiology of AIDS.
Model Checking of Robot Gathering

Recent advances in distributed computing highlight models and algorithms for autonomous mo- bile robots that self-organize and cooperate together in order to solve a global objective. As results, a large number of algorithms have been proposed. These algorithms are given together with proofs to assess their correctness. However, those proofs are informal, which are error prone. This paper presents our study on formal verification of mobile robot algorithms. We first propose a formal model for mobile robot algorithms on anonymous ring shape network under multiplicity and asynchrony assumptions. We specify this formal model in Maude, a specification and pro- gramming language based on rewriting logic. We then use its model checker to formally verify an algorithm for robot gathering problem on ring enjoys some desired properties. As the result of the model checking, counterexamples have been found. We detect the sources of some unforeseen design errors. We, furthermore, give our interpretations of these errors.
Words We Do Not Say—Context Effects on the Phonological Activation of Lexical Alternatives in Speech Production

There is compelling evidence that context strongly influences our choice of words (e.g., whether we refer to a particular animal with the basic-level name “bird” or the subordinate-level name “duck”). However, little is known about whether the context already affects the degree to which the alternative words are activated. In this study, we explored the effect of a preceding linguistic context on the phonological activation of alternative picture names. In Experiments 1 to 3, the context was established by a request produced by an imaginary interlocutor. These requests either constrained the naming response to the subordinate level on pragmatic grounds (e.g., “name the bird! ”) or not (e.g., “name the object! ”). In Experiment 4, the context was established by the speaker’s own previous naming response. Participants named the pictures with their subordinate-level names and the phonological activation of the basic-level names was assessed with distractor words phonologically related versus unrelated to that name (e.g., “birch” vs. “lamp”). In all experiments, we consistently found that distractor words phonologically related to the basic-level name interfered with the naming response more strongly than unrelated distractor words. Moreover, this effect was of comparable size for nonconstraining and constraining contexts indicating that the alternative name was phonologically activated and competed for selection, even when it was not an appropriate lexical option. Our results suggest that the speech production system is limited in its ability of flexibly adjusting and fine-tuning the lexical activation patterns of words (among which to choose from) as a function of pragmatic constraints.
Prevention of depression in at-risk adolescents: a randomized controlled trial.

CONTEXT Adolescent offspring of depressed parents are at markedly increased risk of developing depressive disorders. Although some smaller targeted prevention trials have found that depression risk can be reduced, these results have yet to be replicated and extended to large-scale, at-risk populations in different settings. OBJECTIVE To determine the effects of a group cognitive behavioral (CB) prevention program compared with usual care in preventing the onset of depression. DESIGN, SETTING, AND PARTICIPANTS A multicenter randomized controlled trial conducted in 4 US cities in which 316 adolescent (aged 13-17 years) offspring of parents with current or prior depressive disorders were recruited from August 2003 through February 2006. Adolescents had a past history of depression, current elevated but subdiagnostic depressive symptoms, or both. Assessments were conducted at baseline, after the 8-week intervention, and after the 6-month continuation phase. INTERVENTION Adolescents were randomly assigned to the CB prevention program consisting of 8 weekly, 90-minute group sessions followed by 6 monthly continuation sessions or assigned to receive usual care alone. MAIN OUTCOME MEASURE Rate and hazard ratio (HR) of a probable or definite depressive episode (ie, depressive symptom rating score of > or = 4) for at least 2 weeks as diagnosed by clinical interviewers. RESULTS Through the postcontinuation session follow-up, the rate and HR of incident depressive episodes were lower for those in the CB prevention program than for those in usual care (21.4% vs 32.7%; HR, 0.63; 95% confidence interval [CI], 0.40-0.98). Adolescents in the CB prevention program also showed significantly greater improvement in self-reported depressive symptoms than those in usual care (coefficient, -1.1; z = -2.2; P = .03). Current parental depression at baseline moderated intervention effects (HR, 5.98; 95% CI, 2.29-15.58; P = .001). Among adolescents whose parents were not depressed at baseline, the CB prevention program was more effective in preventing onset of depression than usual care (11.7% vs 40.5%; HR, 0.24; 95% CI, 0.11-0.50), whereas for adolescents with a currently depressed parent, the CB prevention program was not more effective than usual care in preventing incident depression (31.2% vs 24.3%; HR, 1.43; 95% CI, 0.76-2.67). CONCLUSION The CB prevention program had a significant prevention effect through the 9-month follow-up period based on both clinical diagnoses and self-reported depressive symptoms, but this effect was not evident for adolescents with a currently depressed parent.

Effect of Colorant Additive and Thickness on Tensile Properties of Oxo-Biodegradable PE Plastic Bags in Alkaline Solution

Polyethylene (PE) is widely used as packaging materials in the form of plastic bags. After end-use, some of these plastic bags are not properly disposed and may persist in different kinds of environment. Oxo-biodegradable plastics are PE films incorporated with pro-oxidants to promote degradation. As part of the continuing study, changes on the tensile properties of oxo-biodegradable PE plastic bags immersed in alkaline solution at 60 °C are investigated. The effects of colorant additive (varied at two levels) and thickness (varied at three levels) on tensile properties of PE films are reported. Specifically, the tensile strength [MPa], strain at break [%], and elastic modulus [MPa] are monitored with time. It is observed that films undergo degradation which is exhibited by a decrease in all tensile properties after 1008 hours of immersion in alkaline solution. Analysis of variance (ANOVA) shows that the initial tensile strength and elastic modulus, as well as the strain at break and elastic modulus after 1008 hours of immersion, are all affected by colorant additive.
Metabolic costs of mounting an antigen-stimulated immune response in adult and aged C57BL/6J mice.

Animals must balance their energy budget despite seasonal changes in both energy availability and physiological expenditures. Immunity, in addition to growth, thermoregulation, and cellular maintenance, requires substantial energy to maintain function, although few studies have directly tested the energetic cost of immunity. The present study assessed the metabolic costs of an antibody response. Adult and aged male C5BL/6J mice were implanted with either empty Silastic capsules or capsules filled with melatonin and injected with either saline or keyhole limpet hemocyanin (KLH). O2 consumption was monitored periodically throughout antibody production using indirect calorimetry. KLH-injected mice mounted significant immunoglobulin G (IgG) responses and consumed more O2 compared with animals injected with saline. Melatonin treatment increased O2 consumption in mice injected with saline but suppressed the increased metabolic rate associated with an immune response in KLH-injected animals. Melatonin had no effect on immune response to KLH. Adult and aged mice did not differ in antibody response or metabolic activity. Aged mice appear unable to maintain sufficient heat production despite comparable O2 production to adult mice. These results suggest that mounting an immune response requires significant energy and therefore requires using resources that could otherwise be allocated to other physiological processes. Energetic trade-offs are likely when energy demands are high (e.g., during winter, pregnancy, or lactation). Melatonin appears to play an adaptive role in coordinating reproductive, immunologic, and energetic processes.
Developmental regulation of epithelial sodium channel subunit mRNA expression in rat colon and lung.

Na+absorption via amiloride-sensitive Na+ channels is of critical importance in the transition between fetal and neonatal life in several tissues, including the colon, lung, and kidney. To characterize and contrast the mRNA expression of each of the three epithelial Na+ channel complex (ENaC) subunits, we conducted RNase protection assays (RPA) and in situ hybridization in colon and lung in fetal (17, 19, 20, and 21 days) and postnatal (1, 3, 9, 15, and 30 days) rats (r). In the colon the α-, β-, and γ-rENaC subunits showed quantitatively different but qualitatively similar expression. All three subunits gradually increased in abundance from fetal day 19 through day 30 of life. The amount of each subunit on day 30 was approximately three times the amount at day 1. In situ hybridization showed that each subunit was localized to the surface epithelial cells with minimal expression in the crypts. The lung showed a completely different pattern. In contrast to the colon, the total amount of α-rENaC mRNA (by RPA) in the lung increased dramatically from fetal day 19 to 21, whereas β- and γ-rENaC showed modest prenatal increases. The amounts of all three mRNAs fell after birth through day 9 (to about 75% of the day 1 value). On days 15 and 30 the amount of mRNA rose to approach the values on day 1. α-rENaC mRNA abundance always exceeded β- and γ-rENaC, and the quantitative expression was different for α- than for β- and γ-rENaC. In situ hybridization studies showed that all three subunits were expressed in epithelial cells of the bronchi, bronchioles, and alveoli and not in blood vessels. These studies show striking developmental heterogeneity in rENaC mRNA expression between lung and colon, probably reflecting different developmental regulatory mechanisms in these organs.
Chapter # 2 . 5 BIOMEDICAL

Ontology design is an important aspect of medical informatics, and reusability is a key issue that is determined by the level of c ompatibility among ontology concepts and among the theories of the biomedical d omain they convey. In this article, we examine OpenGALEN, the UMLS Semant ic Network, SNOMED CT, the Foundational Model of Anatomy, and t he MENELAS ontology as well as descriptions of the biomedical domain in two general ontologies, OpenCyc and WordNet. Using the represen tatio of Blood in each system, we examine issues in compatibility among th ese ontologies. The presence of additional knowledge is also illustrate d and some issues in creating and aligning biomedical ontologies are dis cus ed.
Impact of Auditory Distractions on Haptic Messages Presented Under the Foot

When compared to vision and audition, communication capabilities of the haptic channel remain underexploited. In this paper, we investigate the impact of auditory distractions on the learning of haptic messages presented under the foot plantar. From a set of six haptic messages that have been designed in order to be easily differentiable one from another, participants have to select four. With and without the presence of auditory distractions, we evaluate the completion time and the number of iteration required to reach an identification rate greater than 95%. For both measures, we observed that having auditory distractions was detrimental to the performances of users.
Comment on: Antibiotic prophylaxis in cataract surgery – An evidence-based approach

Dear Sir, We read with interest the article by Haripriya on intracameral antibiotic prophylaxis. [1] Due to the complexity of a clinical trial addressing this issue, it is very improbable that a new one will be carried out. [1,2] Furthermore, as Javitts stated and Haripriya reaffirmed, with the current observational evidence, to assign a patient to the group without intracameral antibiotic could be even ethically questionable. [1] However, a group of American researchers insist that at least two clinical trials are necessary to make a decision. [2]
IBS-like Symptoms in Patients with Ulcerative Colitis in Deep Remission Are Associated with Increased Levels of Serum Cytokines and Poor Psychological Well-being

Background:Gastrointestinal symptoms (GI) compatible with irritable bowel syndrome (IBS) are common in patients with ulcerative colitis (UC) in remission. The causes of these symptoms remain to be clarified. Our aim was to investigate prevalence and factors associated with IBS-like symptoms in patients with UC in deep remission. Methods:We included 298 patients with UC and used Mayo score, sigmoidoscopy, and fecal calprotectin to define deep remission versus active disease. Presence of IBS-like symptoms according to the Rome III criteria, severity of GI, extraintestinal and psychological symptoms, stress levels, and quality of life were measured with validated questionnaires. Serum cytokines and high-sensitive C-reactive peptide were determined. Results:The criteria for deep remission was fulfilled by 132 patients (44%) and 24 of these fulfilled the Rome III criteria for IBS (18%). Patients with UC in deep remission with IBS-like symptoms had comparable levels of GI symptoms, non-GI somatic symptoms, and quality of life as patients with active UC. The patients with UC in deep remission with IBS-like symptoms had similar levels of fecal calprotectin as patients in deep remission without IBS-like symptoms (18 versus 31 &mgr;g/g, P = 0.11), but higher levels of serum cytokines (interleukin [IL]-1&bgr;, IL-6, IL-13, IL-10 and IL-8, P < 0.05) and higher levels of anxiety (P < 0.001), depression (P = 0.02) and perceived stress (P = 0.03). Conclusions:IBS-like symptoms in patients with UC in deep remission are common, but not as prevalent as previously reported. Poor psychological well-being and increased serum cytokine levels, but not colonic low-grade inflammation, were associated with IBS-like symptoms.
Potassium secretion and the regulation of distal nephron K channels.

K-selective channels in the luminal membranes of distal nephron segments form a key pathway for the secretion of K ions into the urine. This process is important to the control of K balance, particularly under conditions of normal or high K intake. This brief review will cover three issues: 1) the identification of apical K channels, 2) the role of these channels in the maintenance of K homeostasis, and 3) the role of aldosterone in this regulatory process. The large amount of literature on renal K transport has been elegantly summarized in a recent review in this journal [G. Giebisch. Am. J. Physiol.274 ( Renal Physiol. 43): F817-F833, 1998]. Here I will focus on a few prominent unsolved problems.
Long‐term effects of sulfidized silver nanoparticles in sewage sludge on soil microflora

The use of silver nanoparticles (AgNPs) in consumer products such as textiles leads to their discharge into wastewater and consequently to a transfer of the AgNPs to soil ecosystems via biosolids used as fertilizer. In urban wastewater systems (e.g., sewer, wastewater treatment plant [WWTP], anaerobic digesters) AgNPs are efficiently converted into sparingly soluble silver sulfides (Ag2S), mitigating the toxicity of the AgNPs. However, long‐term studies on the bioavailability and effects of sulfidized AgNPs on soil microorganisms are lacking. Thus we investigated the bioavailability and long‐term effects of AgNPs (spiked in a laboratory WWTP) on soil microorganisms. Before mixing the biosolids into soil, the sludges were either anaerobically digested or directly dewatered. The effects on the ammonium oxidation process were investigated over 140 d. Transmission electron microscopy (TEM) suggested an almost complete sulfidation of the AgNPs analyzed in all biosolid samples and in soil, with Ag2S predominantly detected in long‐term incubation experiments. However, despite the sulfidation of the AgNPs, soil ammonium oxidation was significantly inhibited, and the degree of inhibition was independent of the sludge treatment. The results revealed that AgNPs sulfidized under environmentally relevant conditions were still bioavailable to soil microorganisms. Consequently, Ag2S may exhibit toxic effects over the long term rather than the short term. Environ Toxicol Chem 2017;36:3305–3313. © 2017 The Authors.

Observations on the ODMG-93 proposal for an object-oriented database language

Despite its hasty claim, it is NOT a “standard”. Rather, it is a work-in-progress proposal for an object-oriented database language and language bindings to it for C++ and Smalltalk. ODMG (Object-Oriented Database Management Group) is not a formal “standards” body. It is a committee formed by five vendors of first-generation object-oriented database systems (OODB). (For several years, some of these vendors have offered products that are not much more than persistent storage managers for object-oriented programming languages, but the misleading label “Object-Oriented Database System” has been stuck on such products in the market.) And now the misleading label “standard” seems to be attached to the ODMG-93 work-in-progress proposals.
