Perceptions of organizational culture among mental health providers at a Veterans Affairs hospital.

A mixed method approach was utilized to assess the organizational culture of the mental health service line at a large Veterans Affairs (VA) hospital. The goals of the study were to assess the organizational culture, identify how employees differ in perceptions of organizational culture, and identify areas of strength and challenges. Two hundred thirteen participants returned a questionnaire assessing perceptions of organizational culture using the Organizational Culture Assessment Questionnaire (Sashkin & Rosenbach, 2013).

Inclusion of Food Safety Information in Home-delivered U.K. Meal-kit Recipes.

Home-delivered meal-kit recipe boxes provide consumers with fresh, measured ingredients requiring storage, preparation, and cooking by following a recipe card.Previous literature has suggested that including food safety information within recipes may positively impact behavior. Therefore, there is a need to better understand what food safety information is included on the meal-kit recipe cards.

The Perceived Size and Shape of Objects in Peripheral Vision.

Little is known about how we perceive the size and shape of objects in far peripheral vision. Observations made during an artistic study of visual space suggest that objects appear smaller and compressed in the periphery compared with central vision. To test this, we conducted three experiments.

Comparing artistic and geometrical perspective depictions of space in the visual field.

Which is the most accurate way to depict space in our visual field? Linear perspective, a form of geometrical perspective, has traditionally been regarded as the correct method of depicting visual space. But artists have often found it is limited in the angle of view it can depict; wide-angle scenes require uncomfortably close picture viewing distances or impractical degrees of enlargement to be seen properly. Other forms of geometrical perspective, such as fisheye projections, can represent wider views but typically produce pictures in which objects appear distorted.

The effect of matrix metalloproteinase 2 and matrix metalloproteinase 2/9 deletion in experimental post-thrombotic vein wall remodeling.

Background: Vein wall fibrotic injury following deep venous thrombosis (VT) is associated with elevated matrix metalloproteinases (MMPs). Whether and by what mechanism MMP2 contributes to vein wall remodeling after VT is unknown.

Methods: Stasis VT was produced by ligation of the inferior vena cava and tissue was harvested at 2, 8, and 21 days in MMP2 -/- and genetic wild type (WT) mice.

Toll-like receptor 9 signaling is critical for early experimental deep vein thrombosis resolution.

Objective: Toll-like receptors (TLR) bridge innate immunity and host responses, including inflammation. Sterile inflammation such as a venous thrombus (Vt) may involve TLR signaling, including TLR9.

Methods And Results: TLR9 signaling on thrombus resolution was investigated using a mouse model of stasis Vt.

Urokinase plasminogen activator independent early experimental thrombus resolution: MMP2 as an alternative mechanism.

Deep-vein thrombosis (DVT) resolution is thought to be primarily a urokinase plasminogen activator (uPA) -dependent mechanism, although observations suggest other non-fibrinolytic mechanisms may exist. We explored the role of matrix metalloproteinase (MMP) -2 and -9 in early DVT resolution in uPA-deficient mice. Male B6/SVEV (WT) and genetically matched uPA -/- mice underwent inferior vena cava (IVC) ligation to create stasis venous thrombi, with IVC and thrombus harvest.

Ionizing radiation-induced bystander mutagenesis and adaptation: quantitative and temporal aspects.

This work explores several quantitative aspects of radiation-induced bystander mutagenesis in WTK1 human lymphoblast cells. Gamma-irradiation of cells was used to generate conditioned medium containing bystander signals, and that medium was transferred onto naïve recipient cells. Kinetic studies revealed that it required up to 1h to generate sufficient signal to induce the maximal level of mutations at the thymidine kinase locus in the bystander cells receiving the conditioned medium.
