The Association Between Service Connection and Treatment Outcome in Veterans Undergoing Residential PTSD Treatment.

The Department of Veterans Affairs has invested significant time and resources into the treatment of posttraumatic stress disorder (PTSD). Despite concerted efforts, a significant portion of patients do not respond optimally to trauma-focused treatment. One of the factors that has been hypothesized to be associated with treatment response is participation in the Veterans Benefits Administration service-connected disability process.

Habituation of the Light-Startle Response of Orange Head Cockroaches (): Effects of Acclimation, Stimulus Duration, Presence of Food, and Intertrial Interval.

The purpose of this paper is to establish the orange head cockroach () as a useful insect subject for research in comparative psychology by investigating habituation of the light-startle response (LSR). While one goal of comparative psychology is to compare the behavior of a diversity of species, many taxa, including cockroaches, are grossly underrepresented. Our work serves to improve this deficit by investigating habituation learning in the orange head cockroach in four experiments.

The disturbance leg-lift response (DLR): an undescribed behavior in bumble bees.

Background: Bumble bees, primarily and , are becoming increasingly popular organisms in behavioral ecology and comparative psychology research. Despite growing use in foraging and appetitive conditioning experiments, little attention has been given to innate antipredator responses and their ability to be altered by experience. In this paper, we discuss a primarily undescribed behavior, the disturbance leg-lift response (DLR).

Conspecific and interspecific stimuli reduce initial performance in an aversive learning task in honey bees (Apis mellifera).

The purpose of this experiment was to investigate whether honey bees (Apis mellifera) are able to use social discriminative stimuli in a spatial aversive conditioning paradigm. We tested bees' ability to avoid shock in a shuttle box apparatus across multiple groups when either shock, or the absence of shock, was associated with a live hive mate, a dead hive mate, a live Polistes exclamans wasp or a dead wasp. Additionally, we used several control groups common to bee shuttle box research where shock was only associated with spatial cues, or where shock was associated with a blue or yellow color.

Simulated microgravity-mediated reversion of murine lymphoma immune evasion.

No human has returned to the moon since the end of the Apollo program 47 years ago, however, new missions are planned for an orbital outpost. Space radiation and the potential for cancer remain as important issues to the future of human space exploration. While improved shield technologies and protective biologicals are under development, little is known concerning the interaction between cancer cells and host immunity in microgravity.

Prolonged exposure to simulated microgravity diminishes dendritic cell immunogenicity.

Immune dysfunction due to microgravity remains a hurdle in the next step of human space exploration. Dendritic cells (DC) represent a critical component of immunity, given their role in the detection of invaders and the subsequent task of activating T cells to respond and eliminate the threat. Upon encounter with microbes, DC undergo a process of maturation, whereby the cells upregulate the expression of surface proteins and secrete cytokines, both required for the optimal activation of CD4 and CD8 T cells.

Electrostatically Driven CO-π Aromatic Interactions.

A series of -arylimide molecular balances were developed to study and measure carbonyl-aromatic (CO-π) interactions. Carbonyl oxygens were observed to form repulsive interactions with unsubstituted arenes and attractive interactions with electron-deficient arenes with multiple electron-withdrawing groups. The repulsive and attractive CO-π aromatic interactions were well-correlated to electrostatic parameters, which allowed accurate predictions of the interaction energies based on the electrostatic potentials of the carbonyl and arene surfaces.

First Generation Amperometric Biosensing of Galactose with Xerogel-Carbon Nanotube Layer-By-Layer Assemblies.

A first-generation amperometric galactose biosensor has been systematically developed utilizing layer-by-layer (LbL) construction of xerogels, polymers, and carbon nanotubes toward a greater fundamental understanding of sensor design with these materials and the potential development of a more efficient galactosemia diagnostic tool for clinical application. The effect of several parameters (xerogel silane precursor, buffer pH, enzyme concentration, drying time and the inclusion of a polyurethane (PU) outer layer) on galactose sensitivity were investigated with the critical nature of xerogel selection being demonstrated. Xerogels formed from silanes with medium, aliphatic side chains were shown to exhibit significant enhancements in sensitivity with the addition of PU due to decreased enzyme leaching.

Functionalized carbon nanotube adsorption interfaces for electron transfer studies of galactose oxidase.

Modified electrodes featuring specific adsorption platforms able to access the electrochemistry of the copper containing enzyme galactose oxidase (GaOx) were explored, including interfaces featuring nanomaterials such as nanoparticles and carbon nanotubes (CNTs). Electrodes modified with various self-assembled monolayers (SAMs) including those with attached nanoparticles or amide-coupled functionalized CNTs were examined for their ability to effectively immobilize GaOx and study the redox activity related to its copper core. While stable GaOx electrochemistry has been notoriously difficult to achieve at modified electrodes, strategically designed functionalized CNT-based interfaces, cysteamine SAM-modified electrode subsequently amide-coupled to carboxylic acid functionalized single wall CNTs, were significantly more effective with high GaOx surface adsorption along with well-defined, more reversible, stable (≥ 8 days) voltammetry and an average ET rate constant of 0.

Failure to Find Ethanol-Induced Conditioned Taste Aversion in Honey Bees (Apis mellifera L.).

Background: Conditioned taste aversion (CTA) learning is a highly specialized form of conditioning found across taxa that leads to avoidance of an initially neutral stimulus, such as taste or odor, that is associated with, but is not the cause of, a detrimental health condition. This study examines if honey bees (Apis mellifera L.) develop ethanol (EtOH)-induced CTA.

Ebola virus secreted glycoprotein decreases the anti-viral immunity of macrophages in early inflammatory responses.

During Ebola virus (EBOV) infection, secreted glycoprotein (sGP) is found in large quantities in the serum of both patients and infected animal models. It is thought to serve as a decoy for anti-EBOV antibodies. Using an in vitro model incorporating treatment of non-infected human THP-1 macrophages with recombinant EBOV sGP, this study sought to examine the impact of sGP upon key macrophage functions.

Measurement of Solvent OH-π Interactions Using a Molecular Balance.

A molecular torsion balance was designed to study and measure OH-π interactions between protic solvents and aromatic surfaces. These specific solvent-solute interactions were measured via their influence on the folded-unfolded equilibrium of an N-arylimide rotor. Protic solvents displayed systematically weaker solvophobic interactions than aprotic solvents with similar solvent cohesion parameters.

Effects of heat-treatment on the stability and composition of metabolomic extracts from the earthworm .

Environmental metabolomics studies employing earthworms as sentinels for soil contamination are numerous, but the instability of the metabolite extracts from these organisms has been minimally addressed. This study evaluated the efficacy of adding a heat-treatment step in two commonly used extraction protocols (Bligh and Dyer and DO phosphate buffer) as a pre-analytical stabilization method. The resulting metabolic profiles of were assessed using principal component analysis and NMR spectral evaluations.

Resiliency in the practicing marriage and family therapist.

Although burnout in the helping professions is well documented, few studies have examined the phenomenon of the resilient therapist. This study used a grounded theory methodology to construct a theory of therapist resilience. The participants were eight licensed marital and family therapists: five females, three males, all Caucasian, with an average age of 58.

Integrating the older/special needs adoptive child into the family.

This qualitative, grounded theory study investigated 11 families who reported having successfully integrated into their family unit at least one older/special needs adoptee. The theory that emerged through the constant comparative methodology consisted of two categories (Decision to Adopt and Adjustment) and a core category (Developing a Sense of Family). The two categories and core category comprised a process that was informed by the Family Narrative Paradigm and culminated in the successful integration of the child or children into the existing family unit.

The lack of behavioral effects of fenbendazole: a medication for pinworm infection.

Pinworm infection in rodent laboratories is common and often treated with fenbendazole, which is effective and has a low toxicity level. However, very little is known about the behavioral effects of the drug. The purpose of this study was to determine the behavioral effects of fenbendazole on rats tested by using various conditioning and timing procedures.

Factors impacting the assessment of maternal culpability in cases of alleged fetal abuse.

These studies explored attitudes toward maternal culpability in cases of alleged fetal abuse. In experiment one, general culpability for the use of various substances during pregnancy was assessed as well as the impact of other potentially relevant factors. One hundred and twenty students completed the survey.

Common-pool resources and population genomics in Iceland, Estonia, and Tonga.

This paper addresses the application of the ethical concept of trust and the legal and political concept of public trust to population genomics projects in Iceland, Estonia, and Tonga. Focusing on trust and public trust, the paper explores analogies between the genomics projects and the treatment of other common-pool resources, making use of the notion of trust as an ethical demand, derived from the works of Emmanuel Levinas and Knud Eljer Løgstrup. The paper discusses the degree to which the ethical demands for trust and public trust have been established and maintained in the three national population genomics projects.

Low-response-rate conditioning history and fixed-interval responding in rats.

Bar presses by one group of rats were conditioned under a differential-reinforcement-of-low-rate reinforcement schedule immediately prior to conditioning under a fixed-interval schedule. In a second group of rats, bar presses were conditioned first under a differential-reinforcement-of-low-rate schedule and then under a fixed-ratio schedule prior to conditioning under a fixed-interval schedule. Low response rates occurred under the fixed-interval schedule only when it was immediately preceded by low-rate conditioning.
