Contributions of Demand/Withdraw Processes and Alcohol Consumption on Emotional Flooding in Distressed Violent versus Distressed Non-Violent Couples.

Purpose: Although alcohol-related intimate partner violence (IPV) is a serious public health problem, the mechanisms underlying this association are poorly understood. For instance, prior research has shown differences in distressed violent (DV) and distressed nonviolent (DNV) couples' demand/withdraw communication and the extent to which they become emotionally flooded (i.e.

Online support for all: Examining participant characteristics, engagement, and perceived benefits of an online harm reduction, abstinence, and moderation focused support group for alcohol and other drugs.

Objective: Online support groups for individuals with substance use disorders are regularly used, yet little is known about participant engagement patterns. Preliminary research has examined utilization and perceived benefits of an abstinence-focused online social network. This study sought to extend these findings by examining participant characteristics, engagement, and perceived benefits of online support groups for individuals with broader personal substance use goals (Harm reduction, Abstinence, and Moderation Support [HAMS]).

Drag and Track: A Direct Manipulation Interface for Contextualizing Data Instances within a Continuous Parameter Space.

We present a direct manipulation technique that allows material scientists to interactively highlight relevant parameterized simulation instances located in dimensionally reduced spaces, enabling a user-defined understanding of a continuous parameter space. Our goals are two-fold: first, to build a user-directed intuition of dimensionally reduced data, and second, to provide a mechanism for creatively exploring parameter relationships in parameterized simulation sets, called ensembles. We start by visualizing ensemble data instances in dimensionally reduced scatter plots.

Sound at the zoo: Using animal monitoring, sound measurement, and noise reduction in zoo animal management.

A clear need for evidence-based animal management in zoos and aquariums has been expressed by industry leaders. Here, we show how individual animal welfare monitoring can be combined with measurement of environmental conditions to inform science-based animal management decisions. Over the last several years, Disney's Animal Kingdom® has been undergoing significant construction and exhibit renovation, warranting institution-wide animal welfare monitoring.

Effects of guest feeding programs on captive giraffe behavior.

Zoological institutions develop human-animal interaction opportunities for visitors to advance missions of conservation, education, and recreation; however, the animal welfare implications largely have yet to be evaluated. This behavioral study was the first to quantify impacts of guest feeding programs on captive giraffe behavior and welfare, by documenting giraffe time budgets that included both normal and stereotypic behaviors. Thirty giraffes from nine zoos (six zoos with varying guest feeding programs and three without) were observed using both instantaneous scan sampling and continuous behavioral sampling techniques.

Spatial location of indomethacin associated with unimeric amphiphilic carrier macromolecules as determined by nuclear magnetic resonance spectroscopy.

A combination of nuclear magnetic resonance (NMR) techniques including, proton NMR, relaxation analysis, two-dimensional nuclear Overhauser effect spectroscopy, and diffusion-ordered spectroscopy, has been used to demonstrate the spatial location of indomethacin within a unimolecular micelle. Understanding the location of drugs within carrier molecules using such NMR techniques can facilitate rational carrier design. In addition, this information provides insight to encapsulation efficiency of different drugs to determine the most efficient system for a particular bioactive.

Atg23 and Atg27 act at the early stages of Atg9 trafficking in S. cerevisiae.

Atg9 is a conserved multipass transmembrane protein with an essential role in autophagy. In Saccharomyces cerevisiae, it travels through the secretory pathway to a unique compartment, the Atg9 peripheral structures. These structures are then targeted to the phagophore assembly site (PAS), where they are proposed to help deliver membrane to the forming autophagosome.

[HIV infection es IgA nephropathy].

Similar immunological abnormalities exist in IgA nephropathy and HIV infection and several IgA nephropathy cases were reported in HIV-infected patients. To estimate the number of HIV-infected patients in IgA nephropathy, 80 patients with IgA nephropathy were studied for HIV-1 and HIV-2 antibody seropositivity. Although they failed to detect HIV positivity among their IgA nephropathy patients, because of the increasing number of people are being infected with HIV, the screening of IgA nephropathy patients for HIV infection would warrant.

Does hypoxia or hypercarbia independently affect resuscitation from cardiac arrest?

Study Objective: In a previous cardiopulmonary resuscitation (CPR) study in swine, ventilation was associated with improved rate of return of spontaneous circulation (ROSC) compared with nonventilated animals, which had greater hypoxia and hypercarbic acidosis. We used the same model to determine the independent effect of hypoxia and hypercarbic acidosis on ROSC after cardiac arrest.
