Comparison of DHA Omega-3 Polyunsaturated Fatty Acids and Curcumin in ß-amyloid Clearance and Alzheimer\u27s Deceleration

This literature review seeks to contribute information on what is already known about the neurological effects of DHA omega-3 polyunsaturated fatty acids (DHA O3PUFAs) and curcumin, and compare the two substances’ abilities to clear ß-amyloid and alleviate the pathophysiological burden posed by ß-amyloid accumulation. Learning about what natural dietary substances increase β-amyloid clearance has possible implications for improving the conditions of the millions of people living with Alzheimer’s Disease (AD) in terms of increasing life expectancy, creating a healthier way of life, and coming closer to eventually finding a cure

Effect of Particle Diameter on Silver Nanoparticle Aggregation and Dissolution in Aquatic Systems

Silver nanoparticles (AgNPs) are used in many consumer products as an antibacterial agent. The small size of these particles means they are more reactive, because their surface area is larger. However, the widespread usage of AgNPs has consequently led to their release into the aquatic environment, where they have the potential to harm organisms that are not their intended target. Studies have been conducted on the fate and toxicity of AgNPs, but each study uses different sizes, calling into question the consistency of results across different sizes of AgNPs. In addition, a variety of sizes may be utilized in consumer products. One method of determining the behavior of AgNPs in the environment uses the addition of electrolytes to determine their effect on the dissolution and/or aggregation of AgNPs. This research focused on the effect of different concentrations of three different electrolytes (NaNO3, CaCl2 and NaCl) on the aggregation kinetics of three different sizes of citrate-coated silver nanoparticles (20 nm, 50 nm, 80 nm). It was hypothesized that AgNPs with a smaller initial particle size would be less stable than AgNPs with a larger initial particle size in the presence of electrolytes. After the addition of an electrolyte to a silver nanoparticle suspension, the change in size of the particles was measured over time (4 – 15 minutes) using Dynamic Light Scattering. Silver nanoparticles of all three sizes were found to be equally stable in NaNO3 and NaCl, and larger particles were more stable in CaCl2. These results suggest that further investigation into the effect of AgNP size on aggregation may be necessary.No embargoAcademic Major: Environmental Engineerin

Social Dominance Orientation: A Personality Variable Predicting Social and Political Attitudes

Social dominance orientation (SDO), one's degree of preference for inequality among social groups, is introduced. On the basis of social dominance theory, it is shown that (a) men are more social dominance-oriented than women, (b) high-SDO people seek hierarchy-enhancing professional roles and low-SDO people seek hierarchy-attenuating roles, (c) SDO was related to beliefs in a large number of social and political ideologies that support group-based hierarchy (e.g., meritocracy and racism) and to support for policies that have implications for intergroup relations (e.g., war, civil rights, and social programs), including new policies. SDO was distinguished from interpersonal dominance, conservatism, and authoritariansim. SDO was negatively correlated with empathy, tolerance, communality, and altruism. The ramifications of SDO in social context are discussed.African and African American StudiesPsycholog

Mesoscopic phase separation in Nax_xCoO2_2 (0.65≤x≤0.750.65\leq x\leq 0.75)

NMR, EPR and magnetization measurements in Na$_x$CoO$_2$ for $0.65\leq x\leq 0.75$ are presented. While the EPR signal arises from Co$^{4+}$ magnetic moments ordering at $T_c\simeq 26$ K, $^{59}$Co NMR signal originates from cobalt nuclei in metallic regions with no long range magnetic order and characterized by a generalized susceptibility typical of strongly correlated metallic systems. This phase separation in metallic and magnetic insulating regions is argued to occur below $T^*(x)$ ($220 - 270$ K). Above $T^*$ an anomalous decrease in the intensity of the EPR signal is observed and associated with the delocalization of the electrons which for $T<T^*$ were localized on Co$^{4+}$ $d_{z^2}$ orbitals. It is pointed out that the in-plane antiferromagnetic coupling $J\ll T^*$ cannot be the driving force for the phase separation.Comment: 14 figure

Nano-Particle Enhanced Polymer Materials for Space Flight Applications

Recent advances in materials technology both in polymer chemistry and nano-materials warrant development of enhanced structures for space flight applications. This work aims to develop spacecraft structures based on polymer matrix composites (PMCs) that utilize these advancements.. Multi-wall carbon nano-tubes (MWCNTs) are expected to increase mechanical performance, lower coefficient of thermal expansion (CTE), increase electrical conductivity (mitigate electrostatic charge), increase thermal conductivity, and reduce moisture absorption of the resultant space structures. In this work, blends of MWCNTs with PETI-330 were prepared and characterized. The nano-reinforced resins were then resin transfer molded (RTM) into composite panels using M55J carbon fabric and compared to baseline panels fabricated from a cyanate ester (RS-3) or a polyimide (PETI-330) resin containing no MWCNTs. In addition, methods of pre-loading the fabric with the MWCNTs were also investigated. The effects of the MWCNTs on the resin processing properties and on the composite end-use properties were also determined

An exploratory study to examine intentions to adopt an evidence-based HIV linkage-to-care intervention among state health department AIDS directors in the United States

<p>Abstract</p> <p>Background</p> <p>Widespread dissemination and implementation of evidence-based human immunodeficiency virus (HIV) linkage-to-care (LTC) interventions is essential for improving HIV-positive patients' health outcomes and reducing transmission to uninfected others. To date, however, little work has focused on identifying factors associated with intentions to adopt LTC interventions among policy makers, including city, state, and territory health department AIDS directors who play a critical role in deciding whether an intervention is endorsed, distributed, and/or funded throughout their region.</p> <p>Methods</p> <p>Between December 2010 and February 2011, we administered an online questionnaire with state, territory, and city health department AIDS directors throughout the United States to identify factors associated with intentions to adopt an LTC intervention. Guided by pertinent theoretical frameworks, including the Diffusion of Innovations and the "push-pull" capacity model, we assessed participants' attitudes towards the intervention, perceived organizational and contextual demand and support for the intervention, likelihood of adoption given endorsement from stakeholder groups (<it>e.g</it>., academic researchers, federal agencies, activist organizations), and likelihood of enabling future dissemination efforts by recommending the intervention to other health departments and community-based organizations.</p> <p>Results</p> <p>Forty-four participants (67% of the eligible sample) completed the online questionnaire. Approximately one-third (34.9%) reported that they intended to adopt the LTC intervention for use in their city, state, or territory in the future. Consistent with prior, related work, these participants were classified as LTC intervention "adopters" and were compared to "nonadopters" for data analysis. Overall, adopters reported more positive attitudes and greater perceived demand and support for the intervention than did nonadopters. Further, participants varied with their intention to adopt the LTC intervention in the future depending on endorsement from different key stakeholder groups. Most participants indicated that they would support the dissemination of the intervention by recommending it to other health departments and community-based organizations.</p> <p>Conclusions</p> <p>Findings from this exploratory study provide initial insight into factors associated with public health policy makers' intentions to adopt an LTC intervention. Implications for future research in this area, as well as potential policy-related strategies for enhancing the adoption of LTC interventions, are discussed.</p
