BACKGROUND AND GOAL: Symptomatic gallstone disease (SGSD) induced several inflammatory responses and affected extrahepatic bile ducts. Although the pathology and environmental risk factors of gallstone disease (GSD) are well documented, immune or inflammatory responses in SGSD development are still inconclusive. Interleukin 18 (IL18) is a proinflammatory cytokine that plays an ...

Nano- patterning with block-copolymers finds many applications ranging from optics to bioscience. Many of these uses demand highly ordered patterns that are difficult to obtain due to environmental influences during the fabrication. Here we demonstrate that ultrasonication improves the hexagonal order of artificially disturbed micellar nano patterns.

Apoptosis induction is an important host defense mechanism to control viral infection, which is antagonized by viral proteins. Murine cytomegalovirus m41.1 encodes a viral inhibitor of BAK oligomerization (vIBO) that blocks the mitochondrial apoptosis mediator BAK. However, its importance for viral fitness in vivo has not been investigated. Here, we ...

The molecular mechanisms underlying spermine osteo-inductive activity on human adipose-derived stem cells (ASC) grown in 3 dimensional (3D) cultures were investigated. Spermine belongs to the polyamine family, naturally occurring, positively-charged polycations able to control several cellular processes. Spermine was used at a concentration close to that found in platelet-rich plasma ...

Anomalies in prefrontal cortex (PFC) function are posited to underpin difficulties in learning to suppress drug-seeking behavior during abstinence. Because group 1 metabotropic glutamate receptors (mGluRs) regulate drug-related learning, we assayed the consequences of extended access to intravenous cocaine (6 h/d; 0.25 mg/infusion for 10 d) on the PFC expression ...

Adiponectin is a multifunctional cytokine that has a role in regulating inflammation. Here we determined whether adiponectin modulates ischemic acute kidney injury. Compared with wild-type mice, adiponectin-knockout mice were found to have lower serum creatinine and less tubular damage or apoptosis following ischemia/reperfusion injury. This latter process was associated with ...

Mutations in PTEN-induced putative kinase 1 (PINK1) are tightly linked to autosomal recessive Parkinson's disease (PD).

Type I IFNs are induced during microbial infections and have well-characterized antiviral activities. TRAF3 is a signaling molecule crucial for type I IFN production and, therefore, represents a potential target for disarming immune responses. Chlamydia pneumoniae is a human pathogen that primarily infects respiratory epithelial cells; the onset of symptoms ...

Transposable elements (TEs) are epigenetically silenced with extensive DNA methylation. The silent epigenetic marks should, however, be excluded from active genes. By genetic approaches, we study mechanisms to remove the heterochromatin marks from transcribed genes. Based on our observations on control of TE transcription, we propose a possible trigger for ...

Faults in Earth's crust accommodate slow relative motion between tectonic plates through either similarly slow slip or fast, seismic-wave-producing rupture events perceived as earthquakes. These types of behaviour are often assumed to be separated in space and to occur on two different types of fault segment: one with stable, rate-strengthening ...

Isolation or cohorting of infected patients is an old concept. Its purpose is to prevent the transmission of microorganisms from infected or colonized patients to other patients, hospital visitors, and health care workers, who may subsequently transmit them to other patients or become infected or colonized themselves. Because the process ...

Mutations in Connexin 46 are associated with congenital cataracts. The purpose of this project was to characterize cellular and functional properties of two congenital cataract-associated mutations located in the N-terminus of Connexin 46: Cx46D3Y and Cx46L11S, which we found localized to gap junctional plaques like wild-type (WT)Cx46 in transfected HeLa ...

JC polyoma virus (JCV) infection is highly prevalent and usually kept in a persistent state without clinical signs and symptoms. Only during immunocompromise and especially impaired CD4(+) T cell function in the brain, as seen in AIDS patients or natalizumab-treated multiple sclerosis patients, JCV may cause progressive multifocal leukoencephalopathy (PML), ...

Mice overexpressing TLR7 (TLR7.1 mice) are a model of systemic lupus erythematosus pathogenesis and exhibit peripheral myeloid expansion. We show that TLR7.1 mice have a dramatic expansion of splenic cells that derive from granulocyte/macrophage progenitors (GMP) compared with wild-type mice. In the bone marrow, TLR7.1 mice exhibited hallmarks of emergency ...

Nanoporous materials: High-aspect-ratio, ordered porous Co(3) O(4) layers were formed by self-organizing anodization of a cobalt substrate and subsequent annealing. The key for successful formation of such layers is to sufficiently suppress competing oxygen evolution during anodization. The aligned Co(3) O(4) channel layers behave as a highly efficient water oxidation ...

Early ischemic ventricular fibrillation (VF) in the setting of an acute myocardial infarction (AMI) due to thrombotic coronary occlusion remains a major health problem. Several animal studies have shown that platelet-dense granule contents released during thrombus formation can induce arrhythmias. We hypothesize that the platelet release reaction is involved in ...

Shape-selective reactions: Highly selective catalysts are obtained by alkaline and subsequent acid leaching of conventionally prepared zeolites. Active sites that are located in the shape-selective environment of micropores and accessible through mesopores provide high selectivity and activity in acid-catalyzed reactions.
