Macrophage accumulation within the vascular wall is a hallmark of atherosclerosis. Controlling macrophage conversion into foam cells remains a major challenge for treatment of atherosclerotic diseases. Here, we show that Wip1, a member of the PP2C family of Ser/Thr protein phosphatases, modulates macrophage migration and phagocytosis associated with atherosclerotic plaque formation. Wip1 deficiency increases migratory and phagocytic activities of the macrophage under stress conditions. Enhanced migration of Wip1(-/-) macrophages is mediated by Rac1-GTPase and PI3K/AKT signalling pathways...

BACKGROUND CONTEXT: Pelvic Incidence (PI) = Pelvic Tilt (PT) + Sacral Slope (SS) is an established trigonometric equation which can be expanded from studying the fixed pelvis with the spine to a fixed spinopelvic complex with the remnant spine, in scenarios of spinopelvic fusion or ankylosis. For a fixed spinopelvic complex, we propose the equation termed: Lumbar Incidence (LI) = Lumbar Tilt (LT) + Lumbar Slope (LS). PURPOSE: To establish reference values for LI, LT and LS at each lumbar vertebral level, and to show how LI can be used to determine rLL...

Dopamine (DA) modulates cognitive functions in the prefrontal cortex (PFC) and hippocampus. Olfactory bulbectomy (OBX) in mice induces cognitive dysfunctions. Recently, we reported that aripiprazole (ARI) normalizes the behavioral hyper-responsivity to DA agonists in OBX mice. However, it remains unclear whether ARI affects OBX-induced cognitive dysfunctions. To address this question we evaluated ARI-treated and untreated OBX mice in a passive avoidance test. Then, we investigated the effects of ARI on cell proliferation in the hippocampal dentate gyrus by immunohistochemistry, and on c-fos levels in the PFC and hippocampus, as well as nerve growth factor (NGF) levels in the hippocampus by western blotting...

Comamonas sp. JB was used to investigate the cometabolic degradation of dibenzofuran (DBF) and dibenzothiophene (DBT) with naphthalene as the primary substrate. Dehydrogenase and ATPase activity of the growing system with the presence of DBF and DBT were decreased when compared to only naphthalene in the growing system, indicating that the presence of DBF and DBT inhibited the metabolic activity of strain JB. The pathways and enzymes involved in the cometabolic degradation were tested. Examination of metabolites elucidated that strain JB cometabolically degraded DBF to 1,2-dihydroxydibenzofuran, subsequently to 2-hydroxy-4-(3'-oxo-3'H-benzofuran-2'-yliden)but-2-enoic acid, and finally to catechol...

The addition of galactooligosaccharide, (GOS, 0, 1.5, 3 or 4g/100g) on the quality parameters of requeijão cremoso was investigated. Chemical characteristics (pH, moisture, fat and protein), color (L*, a*, b*), water mobility by TD- nuclear magnetic resonance, rheology (flow curve and oscillatory tests), microstructure and sensory acceptance (consumer test) were evaluated. The addition of GOS provided a denser and compact structure and reduced number and size of fat globules. Increased GOS level (3 and 4g/100g) improved the softness and spreadability (decrease of G', G″ and apparent viscosity and an increase of tan δ and melting index) and impacted positively on the aroma and taste of the requeijão cremoso...

Deactivation of an anode catalyst resulting from the poisoning of COad-like intermediates is one of the major problems for methanol and ethanol electro-oxidation reactions (MOR & EOR), and remains a grand challenge towards achieving high performance for direct alcohol fuel cells (DAFCs). Herein, we report a new approach for the preparation of ultrafine cobalt-doped CeO2 dots (Co-CeO2, d = 3.6 nm), which can be an effective anti-poisoning promoter for Pd catalysts towards MOR and EOR in alkaline media. Compared to Pd/CeO2 and pure Pd, the hybrid Pd/Co-CeO2 nanocomposite catalyst exhibited a much enhanced activity and remarkable anti-poisoning ability for both MOR and EOR...

A phosphonate-based metal-organic framework membrane was constructed on a porous anodic alumina membrane (PAAM) substrate for H2/CH4 separation for the first time. Owing to the ultra-micro pore windows, this membrane exhibited effective size exclusion for CH4 molecules but suitable permeance for H2 molecules, giving rise to an exceptional high H2/CH4 separation selectivity.
