The receptor-like protein tyrosine phosphatase CD45 is expressed on the surface of cells of hematopoietic origin and has a pivotal role for the function of these cells in the immune response. Here we report that following infection of macrophages with mouse cytomegalovirus (MCMV) the cell surface expression of CD45 is drastically diminished. Screening of a set of MCMV deletion mutants allowed us to identify the viral gene m42 of being responsible for CD45 down-modulation. Moreover, expression of m42 independent of viral infection upon retroviral transduction of the RAW264...

Chronic obstructive pulmonary disease (COPD) is a debilitating disease resulting in frequent hospitalizations and increased healthcare costs. As leaders of multidisciplinary teams, acute care nurse leaders are challenged to reduce readmissions and costs. In October 2014, the Centers for Medicare and Medicaid Services expanded readmission penalties for 30-day readmissions to include COPD, making this an important issue for nurse leaders. This article describes how a regional medical center was able to decrease COPD readmissions...

PURPOSE OF REVIEW: Geographic disparity in liver transplantation is substantial in the United States, and primarily a byproduct of artificially created zones of organ distribution. In 2016, the United Network for Organ Sharing (UNOS) put forward a formal redistricting proposal with the goal of reducing this variability by regrouping the country's 58 donation service areas into eight new districts. This review provides a summary of the redistricting proposal's methodologies, expected results, criticisms and next steps...

Inflammatory breast cancer (IBC) is a rare and aggressive form of breast cancer, which accounts for approximately 3% of cases of breast malignancies. Diagnosis relies largely on its clinical presentation, and despite a characteristic phenotype, underlying molecular mechanisms are poorly understood. Unique clinical presentation indicates that IBC is a distinct clinical and biological entity when compared to non-IBC. Biological understanding of non-IBC has been extrapolated into IBC and targeted therapies for HER2 positive (HER2+) and hormonal receptor positive non-IBC led to improved patient outcomes in the recent years...

This proof-of-concept study aimed to test whether competition could be a useful tool to increase intensity and amount of self-directed training in neurorehabilitation. Stroke patients undergoing inpatient neurorehabilitation (n=93) conducted self-directed endurance training on a (wheelchair-compatible) bicycle trainer under three experimental conditions: a "Competition" condition and two noncompetition control conditions (repeated randomized within-subject design). Training performance and perceived exertion were recorded and statistically analyzed...

Specimen grossing is a key step in the pathology examination of pancreatic resection specimens. Optimal display of pathologic changes and extensive tissue sampling are important determinants of the quality of pathology reporting. Divergence in macroscopic examination practice has led to considerable variation in the reporting of factors that are of clinical and prognostic significance. This article provides a detailed account of the macroscopic examination procedure with reference to current (inter-)national guidelines and recommendations...

Herpes zoster (HZ) is an acute viral illness characterized by a vesicular rash with unilateral distribution, which can also result in severe complications such as post-herpetic neuralgia (PHN), ophthalmic zoster, stroke or other neurological complications. The estimate incidence in Europe ranges between 2.0 and 4.6 cases per 1,000 person-years, with a sharp increase in >50 year-old subjects. Currently, treatment options for HZ are only partially effective in limiting the acute phase, while the management of complications is complex and often unsatisfactory...

Bacterial biofilms housing dormant persister cells are innately tolerant to antibiotics and disinfectants, yet several membrane-active agents are known to eradicate tolerant bacterial cells. NH125, a membrane-active persister-killer and starting point for development, led to the identification of N-arylated analogues 1 and 2 and displayed improved biofilm-killing potencies and rapid persister-killing activities in stationary cultures of methicillin-resistant Staphylococcus aureus (MRSA). We found 1 and 2 to be superior to other membrane-active agents in biofilm eradication assays with 1 demonstrating minimum biofilm eradication concentrations (MBEC) of 23...

The cause of adaptive protein evolution includes internal (for example, co-evolution of ligand-receptor pairs) and external (for example, adaptation to different ecological niches) mechanisms. Host defense peptides (HDPs) are a class of vertebrate-specific cationic antimicrobial peptides evolving under positive selection. Besides their antibiotic activity, HDPs also exert an effect on multiple host immune cells, thus providing an ideal model to study selective agents driving their evolution. On the basis of a combination of computational and experimental approaches, we studied the evolution of LL-37-type HDPs in mammals, the mature peptide of cathelicidin CAP18 (herein termed CAP18-MP) and investigated the driving force behind the evolution...

In this era of genome-wide association studies (GWAS), the quest for understanding the genetic architecture of complex diseases is rapidly increasing more than ever before. The development of high throughput genotyping and next generation sequencing technologies enables genetic epidemiological analysis of large scale data. These advances have led to the identification of a number of single nucleotide polymorphisms (SNPs) responsible for disease susceptibility. The interactions between SNPs associated with complex diseases are increasingly being explored in the current literature...

Here we report single-step synthesis of white-light emitting carbon dots (CDs) through a green, facile and cheap electrochemical route using graphite rods as the carbon source. Under UV-excitation, the aqueous dispersion of as-synthesized CDs exhibited broad-band emission which covers a significant fraction of visible spectrum; owing to the heterogeneity in the particle-size and surface-functional groups. The CDs were further explored for their potential as UV-to-visible color-convertor under remote-phosphor technology by capping a 365 nm UV-LED chip with CDs-loaded PMMA to obtain color parameters: CIE (0...

The subject of this paper is a search for the long-term immunological effects of alloferon and 3 structural analogues of alloferon, which were earlier characterised by the highest pro-apoptotic activity in Tenebrio molitor. The differences in the actions of these peptides on immune response were observed. Alloferon increased nodulation and significantly phenoloxidase activity in the haemolymph of experimentally infected T. molitor. However, [Phe(p-NH2 )(1) ]- and [Phe(p-OMe)(1) ]-alloferon strongly inhibited cellular and humoral defense of the mealworm against Staphylococcus aureus infection...

BACKGROUND: Chronic antigen exposure and/or aging increases the frequency of T-box expressed in T cells (T-bet)-expressing B-lymphocytes in mice. The frequency and significance of B-cell T-bet expression during chronic hepatitis C (HCV) infection in human subjects has never been described. METHODS: Healthy controls, cirrhotic and non-cirrhotic HCV-infected patients, and non-HCV patients with cirrhosis were recruited. Peripheral blood mononuclear cells were phenotyped for expression of T-bet and related markers by flow cytometry...

Sodium ion hybrid supercapacitors are the potential energy storage devices and recently received an enormous interest. However, the development of desired cathode material and the use of non-aqueous electrolyte remains a great challenge. Hence, we developed the aqueous Na-ion hybrid supercapacitor based on three dimensional fibrous network of NaMnO2. The described cathode material was synthesized by the electro-oxidation of potassium manganese hexacyanoferrate (KMnHCF) nanocubes. The oxidized compound was confirmed as Na0...

We have previously shown that endochondral ossification is finely regulated by the Clock system expressed in chondrocytes during postnatal skeletogenesis. Here we show a sophisticated modulation of bone resorption and bone mass by the Clock system through its expression in bone-forming osteoblasts. Brain and muscle aryl hydrocarbon receptor nuclear translocator-like protein 1 (Bmal1) and Period1 (Per1) were expressed with oscillatory rhythmicity in the bone in vivo, and circadian rhythm was also observed in cultured osteoblasts of Per1::luciferase transgenic mice...

The chemical investigation of marine mollusks has led to the isolation of a wide variety of bioactive metabolites, which evolved in marine organisms as favorable adaptations to survive in different environments. Most of them are derived from food sources, but they can be also biosynthesized de novo by the mollusks themselves, or produced by symbionts. Consequently, the isolated compounds cannot be strictly considered as "chemotaxonomic markers" for the different molluscan species. However, the chemical investigation of this phylum has provided many compounds of interest as potential anticancer drugs that assume particular importance in the light of the growing literature on cancer biology and chemotherapy...
