Trace element concentrations in transplanted and naturally occurring Unionidae mussels, water, sediments, and macrophytes in Cayuga Lake

Field: Environmental Science (Physical Sciences)

This report is a compilation of element concentration data for an EML program whose goal is to determine the environmental fate of combustion-produced pollutants released from a coal-fired electric generating station into an aquatic ecosystem. Because of the enormity of the data set, we have prepared this document to present the data base which will be used in our future interpretive scientific publications. The concentration data for 22 trace elements are reported for naturally occurring fresh water (Unionidae) mussels, macrophytes, lake water, and littoral sediments obtained from Cayuga Lake, NY, the site of the study. Also reported are concentration data for mussels collected from northern Lake George, NY which were transplanted into various locations in Cayuga Lake for periods of up to two years, recovered, and analyzed for the same trace elements. The description of the sampling sites, sampling methodologies, and the results of the analytical quality control programs are presented. Ratios of trace elements in different compartments of the Cayuga Lake ecosystem and correlation coefficients determined by comparing element concentrations in the biota, water, and sediment with distance from the coal-fired power plant are also presented. 21 refs., 2 figs., 33 tabs.
Role for Actin Filament Turnover and a Myosin II Motor in Cytoskeleton-driven Disassembly of the Epithelial Apical Junctional Complex

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Disassembly of the epithelial apical junctional complex (AJC), composed of the tight junction (TJ) and adherens junction (AJ), is important for normal tissue remodeling and pathogen-induced disruption of epithelial barriers. Using a calcium depletion model in T84 epithelial cells, we previously found that disassembly of the AJC results in endocytosis of AJ/TJ proteins. In the present study, we investigated the role of the actin cytoskeleton in disassembly and internalization of the AJC. Calcium depletion induced reorganization of apical F-actin into contractile rings. Internalized AJ/TJ proteins colocalized with these rings. Both depolymerization and stabilization of F-actin inhibited ring formation and disassembly of the AJC, suggesting a role for actin filament turnover. Actin reorganization was accompanied by activation (dephosphorylation) of cofilin-1 and its translocation to the F-actin rings. In addition, Arp3 and cortactin colocalized with these rings. F-actin reorganization and disassembly of the AJC were blocked by blebbistatin, an inhibitor of nonmuscle myosin II. Myosin IIA was expressed in T84 cells and colocalized with F-actin rings. We conclude that disassembly of the AJC in calcium-depleted cells is driven by reorganization of apical F-actin. Mechanisms of such reorganization involve cofilin-1-dependent depolymerization and Arp2/3-assisted repolymerization of actin filaments as well as myosin IIA-mediated contraction.
Molecular Recognition of Nerve Agents and Their Organophosphorus Surrogates: Toward Supramolecular Scavengers and Catalysts

Field: Chemistry (Physical Sciences)

Abstract Nerve agents are tetrahedral organophosphorus compounds (OPs) that were developed in the last century to irreversibly inhibit acetylcholinesterase (AChE) and therefore impede neurological signaling in living organisms. Exposure to OPs leads to a rapid development of symptoms from excessive salivation, nasal congestion and chest pain to convulsion and asphyxiation which if left untreated may lead to death. These potent toxins are prepared on a large scale from inexpensive staring materials, making it feasible for terrorist groups or states to use them against military and civilians. The existing antidotes provide limited protection and are difficult to apply to a large number of affected individuals. While new prophylactics are currently being developed, there is still need for therapeutics capable of both preventing and reversing the effects of OP poisoning. In this review, we describe how the science of molecular recognition can expand the pallet of tools for rapid and safe sequestration of nerve agents.
Job Search and Hiring with Limited Information about Workseekers’ Skills

Field: Economics, Econometrics and Finance (Social Sciences)

We assess South African workseekers’ skills and disseminate the assessment results to explore how limited information affects firm and workseeker behavior. Giving workseekers assessment results that they can credibly share with firms increases workseekers’ employment and earnings and better aligns their skills, beliefs and search strategies. Giving workseekers assessment results that they cannot easily share with firms has similar effects on beliefs and search, but smaller effects on employment and earnings. Giving assessment results only to firms shifts interview decisions. These findings show that getting credible skill information to the right agents can improve outcomes in the labor market.

Data of "An Observational Study of Out-of-Hospital Cardiac Arrests Reported In Indian Print Media"

Field: Medicine (Health Sciences)

Background:Newspapers in India often report incidents of cardiac arrest. Media reports are a source for raising awareness of cardiac arrest and Cardiopulmonary Resuscitation (CPR) among the public. Data on Out-of-Hospital Cardiac Arrests(OHCA) is limited in India. Methods: The study aims at evaluating the reports of OHCA as reported in print media (particularly newspapers in India) with Utstein template-portrayal of cardiac arrest, demographics, patient and resuscitation characteristics. Methods: Study design: This is an observational study of a cohort of cardiac arrests reported in selected Indian English newspapers. Setting:There has been an attempt in securing national data on OHCA.There is no single source or agency in India through which all media reports can be collected. Only English newspapers with websites and data available for public domain were accessed for reports of cardiac arrest. Participants: Subjects from reports of cardiac arrest in various locations in India. Sources of data: Newspaper reports from English language Indian newspapers with wider circulation. They were retrieved from the archives during 2001-2019 from the websites of : The Hindu, The New Indian Express, The Times of India, Hans India and The Pioneer. All the articles are screened for eligibility. Initially, those reports with a search word "cardiac arrest" were retrieved. Articles eligible for inclusion included persons sustaining cardiac arrest at several Indian locations. Reports with no reference to a possible cardiac arrest were excluded. Articles in different newspapers of the same cardiac arrest victim were searched for any additional information, and only the best report was included. Those due to obvious possible non-cardiac causes such as trauma were excluded. Data related to Utstein variables were extracted from these reports. Data of OHCA subjects were selected for analysis. Results: 1779 reports reviewed and 1703 selected after excluding 76. Of these, 279 reports did not specify whether it was an In-Hospital Cardiac Arrest (IHCA)or OHCA. Of the remaining 1424 reports,377 reports were IHCA, and 1047 were OHCA. 1047 OHCA cases selected for analysis. The study noted male preponderance and a median age of 51--60 years. OHCA commonly occurred in residential locations, followed by public buildings, other places and street/highways. Prior risk factors, heart disease, symptoms were reported in some reports. Of 15 subjects who received CPR, 11 were reported to have survived. Though demographic data is reported in the majority, there is poor reporting of clinical and resuscitation details. Limitations:The study may not reflect the total number of OHCA reported as accessing the information from newspapers in different languages from different States was a limiting factor. Conclusions: The study gives a glimpse of OHCA in India and emphasizes the need for elaborate reporting of data on cardiac arrest. The crucial role of media is recognized.

Commentary Measurements in the intensive care unit: what do they mean?

Field: Medicine (Health Sciences)

Intensivists depend upon a large number of measurements to make daily decisions in the ICU. However, the reliability of these measures may be jeopardized by the effects of therapy. Moreover, in critical illness, what is normal is not necessarily optimal. Procalcitonin, a putative marker of occult infection, is emerging as a valuable diagnostic marker in the ICU. Although questions remain regarding its specificity, an increasing body of work suggests that it is reliably elevated in the setting of infection. As demonstrated by Level and colleagues in this issue of Critical Care, its utility as a diagnostic marker is not affected by concomitant hemodialysis.
Infrared finite effective charge of QCD

Field: Physics and Astronomy (Physical Sciences)

We show that the gauge invariant treatment of the Schwinger-Dyson equations of QCD leads to an infrared finite gluon propagator, signaling the dynamical generation of an effective gluon mass, and a non-enhanced ghost propagator, in qualitative agreement with recent lattice data.The truncation scheme employed is based on the synergy between the pinch technique and the background field method.One of its most powerful features is that the transversality of the gluon self-energy is manifestly preserved, exactly as dictated by the BRST symmetry of the theory.We then explain, for the first time in the literature, how to construct non-perturbatively a renormalization group invariant quantity out of the conventional gluon propagator.This newly constructed quantity serves as the natural starting point for defining a non-perturbative effective charge for QCD, which constitutes, in all respects, the generalization in a non-Abelian context of the universal QED effective charge.This strong effective charge displays asymptotic freedom in the ultraviolet, while in the low-energy regime it freezes at a finite value, giving rise to an infrared fixed point for QCD.Some possible pitfalls related to the extraction of such an effective charge from infrared finite gluon propagators, such as those found on the lattice, are briefly discussed.

Towards Transculturalism in Tackling Diversity for Literacy Teacher Education

Field: Arts and Humanities (Social Sciences)

The approaches towards addressing diversity in literacy teacher education within the United States typically position in-service teachers to focus on differences within certain student populations as they operate from positions of power in relation to "diverse students". There is clear evidence in the research of the need for more culturally responsive and culturally sustaining pedagogy that appropriately addresses teachers' capacity to meet the needs of culturally and linguistically diverse learners in the United States. The term "culturally relevant pedagogy" first grew out of Gloria Ladson-Billings' desire to address the needs of underrepresented African American students in US K-12 schools in a desire to develop pedagogical principles for all students. The chapter examines the ways in which American in-service teachers interacting with an Afro-Caribbean immigrant literacy educator in graduate literacy course approached diversity based on differences between themselves and students as opposed to differences within certain student populations.
ETHICAL AND SCIENTIFIC CONSIDERATIONS FOR THE DESIGN AND IMPLEMENTATION OF THE PREP DEMONSTRATION PROJECT IN NIGERIA

Field: Health Professions (Health Sciences)

Background This abstract highlights the ethical and scientific considerations that informed the development and review of the Nigeria PrEP demonstration study protocol. Methods A desk review was conducted on all the meeting reports that led to the choice of the study design and the decisions made to modify the protocol for the PrEP demonstration project in Nigeria. The study focused on the ethical and scientific rationales for modifying the Partners' PrEP Sero-discordant protocol for this study as well as for the first and second protocol amendments of this study. Results The decision to conduct a PrEP study was based on the outcome of a modelling study that suggested that sero-discordant couples will benefit from access to condom, TasP, and PrEP. Next, the decisions on the target population for the PrEP demonstration study, the models for evaluation at specific project site, and the design of the community engagement programme were reached through a formative research which engaged 611 individuals using multiple media. The study did not exclude study participants based on Hepatitis status and HIV risk profile since Truvada was an effective hepatitis treatment and the prevalence of hepatitis infection is high in Nigeria. Participants' interest in PrEP use was considered enough reason to prescribe PrEP in a country where uptake of ARV is slow and stigma associated with ARV use is high. Also, HIV-negative partners could assess when the viral load of the HIV-positive partner was 400 copies/ml. Since adherence was a challenge for PrEP use, adherence was enhanced through the use of the MEMS Cap. Conclusions A PrEP demonstration study that mimics real life scenarios for PrEP provision within public health care institutions and is designed on the basis of community consultations, ethical and scientific considerations, will enhance the success of PrEP roll-out in resource-limited settings like Nigeria.
Revascularization of the Ischemic Limb

Field: Medicine (Health Sciences)

Atherosclerosis is a generalized disorder, but the process in a given patient may be limited to one artery or even to a portion of a single artery and remain so for a considerable length of time. It is well known that persons with intermittent claudication may survive for many years without loss of the limb or any other serious cardiovascular complication. This is particularly true of the relatively younger patient with atherosclerotic occlusion of the lower abdominal aorta and its bifurcation but is also seen in the patient with chronic occlusion of the superficial femoral artery. The Natural History of Occlusion of the Superficial Femoral Artery We are all familiar with the elderly gentleman who has had intermittent claudication of his calves for as long at 5 to 10 years, who finally succumbs to a cerebrovascular accident or myocardial infarct without having had serious ischemic changes in the feet. Then,
Analysis of personality ratings using the social relations model

Field: Psychology (Social Sciences)

Three datasets (N=90, 65, and 88) each provided three modes of assessment of the Big Five factors: Questionnaire, self-rating and peer-ratings. All participants completed the questionnaire before meeting in small discussion groups; afterward, participants rated one another and themselves. Kenny's Social Relations Model (SRM) was used (a) to partition target, rater and relationship components of the rating data, and (b) to correlate the three stable component scores with the questionnaire and self-rating measures. For each of the Big Five, such statistics provide measures of reliability and validity as well as indexing projection, reciprocity, and self-enhancement. It was hypothesized that (a) the three assessment modes would converge, (b) target variance would be stronger than in previous research, (c) self-ratings would be more positive than other-ratings, and (d) projection would be significant but reciprocity would not. In general, these hypotheses were confirmed.
Quasi-amateur porn : a brief episode of unceasing carnival

Field: Arts and Humanities (Social Sciences)

This essay explores meaning complexity of pornographic materials conceived as quasi-private though its true “professional” provenience. The main subjects of analysis are easily accessible ads of various paid X-rated websites. Author treats advertising texts as a source of knowledge about narrative strategies and stereotypes. An interpretative tool chosen for the task is Mikhail Bakhtin’s Theory of Carnival – in particular: concept of “grotesque realism” and four fundamental categories of “carnivalesque” (familiar interaction between people, eccentric behavior, misalliances, sacrilegious). The article is based on the results of research conducted in the years 2002-2004.
Analyze the Status of Young Women in Patriarchal Societies Films through the Theories of Gaze——Shots of Gazes in "Thelma and Louise"

Field: Arts and Humanities (Social Sciences)

The Third Feminist Movement in America is the setting for the iconic feminist movie "Thelma and Louise." The third feminist movement at the time demanded the abolition of social gender norms, prejudices, and more while thinking outside of the traditional feminist paradigm. Hollywood movies must continuously examine the significance of women's existence from the standpoint of cinematic art because Hollywood is the primary source of feminism. Therefore, the focus of this essay is on how to use gaze theories, including male gaze theory and female gaze theory, to depict the status of women in patriarchal society films. The term "man gaze" describes how the camera confines women because males predominate the film industry and consequently make decisions based on their own values and interests. The female gaze is a way for women to reclaim the sovereignty of their bodies; it is a gaze on women from a female perspective. Through a series of analyses of film techniques and camera language, combined with the gaze theory proposed by Laura Mulvey, it can be hoped to discuss the current situation of contemporary women in a patriarchal society. Specifically, by analyzing the male gaze and female gaze in the film "Thelma & Louise", it can be hoped to illustrate the poor living conditions of women in a patriarchal society, where the male gaze can be seen everywhere in life.
