PURPOSE: Knowledge of the psychological distress of long- and very long-term (>10 years) prostate cancer (PC) survivors is limited. This study intended to examine the parameters influencing anxiety related to prostate-specific antigen (PSA) and PC in long-term survivors after radical prostatectomy. METHODS: We surveyed 4719 PC survivors from the German multicenter prospective database "Familial Prostate Cancer." We evaluated the association of PC-related anxiety (MAX-PC) with sociodemographic characteristics, family history of PC, global health status/quality of life (EORTC QLQ-C30), depression and anxiety (PHQ-2; GAD-2), latest PSA level, time since radical prostatectomy, and current therapy...

BACKGROUND/PURPOSE: Bioaggregates such as Portland cement (PC) can be an economical alternative for mineral trioxide aggregate (MTA) with additional benefit of less discoloration. MTA has been known to induce differentiations of several dental cells. MicroRNAs are important regulators of biological processes, including differentiation, physiologic homeostasis, and disease progression. This study is to explore how PC enhances the differentiation of periodontal ligament (PDL) cells in microRNAs level...

OBJECTIVE: To identify and describe a list of sentinel events (SEs) for Primary Care (PC). METHODODOLOGY: A structured experts' consensus was obtained by using two online questionnaires. The participants were selected because of their expertise in PC and patient safety. The first questionnaire assessed the suitability of the hospital SEs established in the National Quality Forum 2006 for use in PC via responses of "yes", "no", or "yes but with modification". In the latter case, a re-wording of the SE was requested...

REVIEW
Marie Touchon, Jorge A Moura de Sousa, Eduardo Pc Rocha
Bacteriophages and archaeal viruses contribute, through lysogenic conversion or transduction, to the horizontal transfer of genetic material between microbial genomes. Recent genomics, metagenomics, and single cell studies have shown that lysogenic conversion is widespread and provides hosts with adaptive traits often associated with biotic interactions. The quantification of the evolutionary impact of transduction has lagged behind and requires further theoretical and experimental work. Nevertheless, recent studies suggested that generalized transduction plays a role in the transfer of antibiotic resistance genes and in the acquisition of novel genes during intra-specific bacterial competition...

BACKGROUND AND AIMS: The pathological process of atherosclerosis is closely related to lipid accumulation at arterial wall caused by lipoproteins transporting lipids through blood. In this study, we investigate the lipid composition in the plasma of apolipoprotein E deficient (ApoE(-/-)) mice fed a high-fat diet to reveal atherosclerosis-induced dyslipidemia. METHODS: ApoE(-/-) and corresponding wild-type C57BL/6J mice were used as the pathology model and control, respectively, and were fed a high-fat or normal diet...

Choline phosphate (CP) containing polymers modified surfaces have been shown good resist to the adhesion of proteins while prompt the attaching of mammalian cells due to the dipole pairing between the CP groups of the polymer and the phosphorylcholine (PC) groups on the cell membrane. However, the antifouling activities of CP modified surface against microbes have not been investigated at present. In addition, CP containing polymers modified surface with different molecular architectures has not been prepared and studied...

PURPOSE: Phenolic compounds (PC) of virgin olive oil exert several biochemical and pharmacological beneficial effects. Some dietary PC seem to prevent/improve obesity and metabolic-related disorders such as non-alcoholic fatty liver disease (NAFLD). We investigated the possible effects of PC extracted from olive pomace (PEOP) and of the main single molecules present in the extract (tyrosol, apigenin, oleuropein, p-coumaric and caffeic acid) in protecting hepatocytes and endothelial cells against triglyceride accumulation and oxidative stress...

Thioarsenates form from arsenite under sulfate-reducing conditions, e.g. in rice paddy soils, and are structural analogues to arsenate. Even though rice is one of the most important sources of human arsenic (As) intake, nothing is published about uptake, toxicity, or tolerance of thioarsenates in plants. Experiments using the model system Arabidopsis thaliana showed that monothioarsenate is less toxic than arsenite, but more toxic than arsenate at concentrations >= 25 µM As, reflected in stronger seedlings growth inhibition on agar plates...

Toner formulations used by laser printers (LP) and photocopiers (PC), collectively called "toner-based printing equipment" (TPE), are nano-enabled products (NEP) because they contain several engineered nanomaterials (ENM) that improve toner performance. It has been shown that during consumer use (printing), these ENM are released in the air, together with other semi-volatile organic nanoparticles, and newly formed gaseous co-pollutants such as volatile organic compounds (VOC). The aim of this review is to detail and analyze physico-chemical and morphological (PCM), as well as the toxicological properties of particulate matter (PM) emissions from TPE...

Formulating electrolytes with solvents of low freezing points and high dielectric constants is a direct approach to extending the service temperature range of lithium (Li)-ion batteries (LIBs). In this work, we report such wide temperature electrolyte formulations by optimizing the content of ethylene carbonate (EC) in the ternary solvent system of EC, propylene carbonate (PC) and ethyl methyl carbonate (EMC) with LiPF6 salt and CsPF6 additive. An extended service temperature range from -40°C to 60°C was obtained in LIBs with lithium nickel cobalt aluminum mixed oxide (LiNi0...

Several studies have indicated that abnormal prenatal changes in the circulating glucocorticoids (GCs), induced by either maternal stress or exogenous GC administration, significantly alter the development of Purkinje cells (PCs). Among the suggested mechanisms that could mediate this GC-dependent PC susceptibility are changes in the expression of type-1 metabotropic glutamate receptors (mGluR1). In the current study, we analyzed whether a single course of prenatally administered betamethasone phosphate (BET) in pregnant rats increased the immunohistochemical expression of mGluR1 in PCs and decreased PC dendritic growth...

Producing hierarchical porous N-doped carbon from renewable biomass is an essential and sustainable way for future electrochemical energy storage. Herein we cost-efficiently synthesized N-doped porous carbon from renewable cellulose by using urea as a low-cost N source, without any activation process. The as-prepared N-doped porous carbon (N-doped PC) had a hierarchical porous structure with abundant macropores, mesopores and micropores. The doping N resulted in more disordered structure, and the doping N content in N-doped PC could be easily tunable (0...

Magnetic nanoparticles represent a new paradigm for molecular targeting therapy in cancer. However, the transformative targeting potential of magnetic nanoparticles has been stymied by a key obstacle-safe delivery to specified target cells in vivo. As cancer cells grow under nutrient deprivation and hypoxic conditions and decorate cell surface with excessive sialoglycans, sialic acid binding lectins might be suitable for targeting cancer cells in vivo. Here we explore the potential of magnetic nanoparticles functionalized with wheat germ lectin (WGA) conjugate, so-called nanomagnetolectin, as apoptotic targetable agents for prostate cancer...

Some bacterial strains such as Komagataeibacter xylinus are able to produce cellulose as an extracellular matrix. In comparison to wood-based cellulose, bacterial cellulose (BC) holds interesting properties such as biodegradability, high purity, water-holding capacity and superior mechanical and structural properties. Aiming towards improvement in BC production titer and tailored alterations to the BC film, we engineered K. xylinus to overexpress partial and complete bacterial cellulose synthase operon that encodes activities for BC production...

Purkinje cells (PCs) generate two types of action potentials, called simple and complex spikes (SSs and CSs). We first investigated the CS-associated modulation of SS activity and its relationship to the zebrin status of the PC. The modulation pattern consisted of a pre-CS rise in SS activity, and then, following the CS, a pause, a rebound, and finally a late inhibition of SS activity for both zebrin positive (Z+) and negative (Z-) cells, though the amplitudes of the phases were larger in Z+ cells. Moreover, the amplitudes of the pre-CS rise with the late inhibitory phase of the modulation were correlated across PCs...
