Stopping Autoinducer-2 Chatter by Means of an Indigenous Bacterium ( Acinetobacter sp. DKY-1): A New Antibiofouling Strategy in a Membrane Bioreactor for Wastewater Treatment.

Bacterial quorum quenching (QQ) by means of degrading signaling molecules has been applied to antibiofouling strategies in a membrane bioreactor (MBR) for wastewater treatment. However, the target signaling molecules have been limited to N-acyl homoserine lactones participating in intraspecies quorum sensing. Here, an approach to disrupting autoinducer-2 (AI-2) signaling molecules participating in interspecies quorum sensing was pursued as a next-generation antibiofouling strategy in an MBR for wastewater treatment.

Polypharmacy in Home Care in Europe: Cross-Sectional Data from the IBenC Study.

Background: Home care (HC) patients are characterized by a high level of complexity, which is reflected by the prevalence of multimorbidity and the correlated high drug consumption. This study assesses prevalence and factors associated with polypharmacy in a sample of HC patients in Europe.

Methods: We conducted a cross-sectional analysis on 1873 HC patients from six European countries participating in the Identifying best practices for care-dependent elderly by Benchmarking Costs and outcomes of community care (IBenC) project.

Interactions between drugs and geriatric syndromes in nursing home and home care: results from Shelter and IBenC projects.

Aim: Drugs may interact with geriatric syndromes by playing a role in the continuation, recurrence or worsening of these conditions. Aim of this study is to assess the prevalence of interactions between drugs and three common geriatric syndromes (delirium, falls and urinary incontinence) among older adults in nursing home and home care in Europe.

Methods: We performed a cross-sectional multicenter study among 4023 nursing home residents participating in the Services and Health for Elderly in Long-TERm care (Shelter) project and 1469 home care patients participating in the Identifying best practices for care-dependent elderly by Benchmarking Costs and outcomes of community care (IBenC) project.

In Vitro Evaluation of Glycoengineered RSV-F in the Human Artificial Lymph Node Reactor.

Subunit vaccines often require adjuvants to elicit sustained immune activity. Here, a method is described to evaluate the efficacy of single vaccine candidates in the preclinical stage based on cytokine and gene expression analysis. As a model, the recombinant human respiratory syncytial virus (RSV) fusion protein (RSV-F) was produced in CHO cells.

Engineering of CHO Cells for the Production of Recombinant Glycoprotein Vaccines with Xylosylated N-glycans.

Xylose is a general component of -glycans in mammals. Core-xylosylation of -glycans is only found in plants and helminth. Consequently, xylosylated -glycans cause immunological response in humans.

A continuous single organic phase process for the lipase catalyzed synthesis of peroxy acids increases productivity.

The design of an optimal process is particularly crucial when the reactants deactivate the biocatalyst. The reaction cascades of the chemo-enzymatic epoxidation where the intermediate peroxy acid is produced by an enzyme are still limited by enzyme inhibition and deactivation by hydrogen peroxide. To avoid additional effects caused by interfaces (aq/org) and to reduce the process limiting deactivation by the substrate hydrogen peroxide, a single-phase concept was applied in a fed-batch and a continuous process (stirred tank), without the commonly applied addition of a carrier solvent.

Multi-level glyco-engineering techniques to generate IgG with defined Fc-glycans.

Immunoglobulin G (IgG) mediates its immune functions through complement and cellular IgG-Fc receptors (FcγR). IgG contains an evolutionary conserved N-linked glycan at position Asn297 in the Fc-domain. This glycan consists of variable levels of fucose, galactose, sialic acid, and bisecting N-acetylglucosamine (bisection).

Social and functional health of home care clients with different levels of cognitive impairments.

Objectives: The ability to manage one's life with some degree of independence, to fulfill basic obligations, and to participate in social activities are social functions that delineate the core of 'social health'. We examine to what extent clients of community care in Europe (n = 2884) complete such activities despite their cognitive problems. We focus on mildly and moderately impaired people, aged 65+ years.

Symbiosis, dysbiosis, and rebiosis-the value of metaproteomics in human microbiome monitoring.

As just one species in the larger ecosystem, the health and disease status of human beings is highly dependent on other biological species in their environment, both inside and outside of the human body. Since proteins are the major functional building blocks of the biological world, most homeostasis regulations are realized at the protein level. Diagnosis-oriented monitoring of cross-species proteostasis will constitute a solid basis for next-generation preventive medicine.
