Psychosocial working conditions and violence prevention climate in German emergency departments - a cross-sectional study.

Background: Emergency departments (EDs) are high pressure work environments with several psychosocial job demands, e.g., violence, and job resources, e.

Case report: Maintaining altered states of consciousness over repeated ketamine infusions may be key to facilitate long-lasting antidepressant effects: some initial lessons from a personalized-dosing single-case study.

Background: The interest in psychoactive agents for treating mental disorders has gathered a growing body of scientific interest. However, research on the relationship between altered states of consciousness (ASCs) and ketamine's antidepressant properties is still limited. Likewise, approaches to sustain early treatment success for the long-term are needed.

Violence Prevention Climate and Health-Oriented Leadership in German Emergency Departments.

Emergency departments (EDs) are high-risk environments for workplace violence. Research into techniques to prevent violence has less frequently explored the influence of leadership. This study aims to analyze the association of leadership with the prevention of violence using the concepts of health-oriented leadership (HoL) and the violence prevention climate (VPC).

"I think we still do too little": measures to prevent violence and aggression in German emergency departments - a qualitative study.

Background: Healthcare workers employed in emergency departments (EDs) are particularly affected by physical and verbal violence. Violent assaults can be committed by both patients and their attendants. Research on interventions for violence prevention is limited and previous studies report that ED employees feel unprepared for violent incidents.

[Emergency care as a high-risk workplace-Measures to deal with violence against employees].

Background: Many employees in the field of emergency care experience verbal and physical violence caused by patients or visitors. The aim of this project is to gain insights into which measures are available to deal with violence in emergency care and how employees subjectively evaluate them.

Methods: A nationwide cross-sectional online survey was conducted in 2020.

Buddhist-like opposite diminishing and non-judging during ketamine infusion are associated with antidepressant response: an open-label personalized-dosing study.

Cognition that is not dominated by thinking in terms of opposites (opposite diminishing) or by making judgments (non-judging) can be found both in Buddhist/mindfulness contexts and in mental states that are fostered by dissociative psychedelics (-methyl-D-aspartate antagonists) such as ketamine. Especially for the Buddhist/mindfulness case, both opposite diminishing and non-judging have been proposed to relate to mental well-being. Whether ketamine-occasioned opposite diminishing and/or non-judging relate to increased mental well-being in the form of antidepressant response is unknown, and was investigated in the present study.

Exploring job demands and resources in psychotherapists treating displaced people-A scoping review.

: Little is known about the occupational health of psychotherapists treating displaced people. Therefore, the literature was explored regarding job demands, job resources, as well as work- and health-related outcomes. The Job Demands-Job Resources model (JD-R model) according to Bakker and Demerouti served as theoretical framework.

A cell surface-exposed protein complex with an essential virulence function in Ustilago maydis.

Plant pathogenic fungi colonizing living plant tissue secrete a cocktail of effector proteins to suppress plant immunity and reprogramme host cells. Although many of these effectors function inside host cells, delivery systems used by pathogenic bacteria to translocate effectors into host cells have not been detected in fungi. Here, we show that five unrelated effectors and two membrane proteins from Ustilago maydis, a biotrophic fungus causing smut disease in corn, form a stable protein complex.

New generation of cell-penetrating peptides: Functionality and potential clinical application.

Cell-penetrating peptides (CPPs) can transport various cargoes through membranes of live cells. Since the first generations of CPPs suffered from insufficient cell and tissue selectivity, stability against proteases, and escape from endosomes, a new generation of peptides, with optimized properties, was developed. These are either derived from natural sources or created through the combination of multivalent structures.

A kiwellin disarms the metabolic activity of a secreted fungal virulence factor.

Fungi-induced plant diseases affect global food security and plant ecology. The biotrophic fungus Ustilago maydis causes smut disease in maize (Zea mays) plants by secreting numerous virulence effectors that reprogram plant metabolism and immune responses. The secreted fungal chorismate mutase Cmu1 presumably affects biosynthesis of the plant immune signal salicylic acid by channelling chorismate into the phenylpropanoid pathway.

New generation CPPs show distinct selectivity for cancer and noncancer cells.

In the last three decades, many new cell-penetrating peptides (CPPs) were developed that exhibited enhanced cell selectivity. Thus, we aimed to validate the tumor cell selectivity of peptides from this new generation, namely fragments mini-crotamine and mini-maurocalcine. Both of these peptides are derived from venoms.

Transduction and transfection of difficult-to-transfect cells: Systematic attempts for the transfection of protozoa Leishmania.

Cell-penetrating peptides (CPPs) are used to internalize different cargoes, including DNA, into live mammalian and plant cells. Despite many cells being easily transfected with this approach, other cells are rather "difficult" or "hard to transfect," including protist cells of the genus Leishmania. Based on our previous results in successfully internalizing proteins into Leishmania tarentolae cells, we used single CPPs and three different DNA-binding proteins to form protein-like complexes with plasmids covered with CPPs.

Single and Multiplexed Gene Editing in Using CRISPR-Cas9.

The smut fungus is an established model organism for elucidating how biotrophic pathogens colonize plants and how gene families contribute to virulence. Here we describe a step by step protocol for the generation of CRISPR plasmids for single and multiplexed gene editing in Furthermore, we describe the necessary steps required for generating edited clonal populations, losing the Cas9 containing plasmid, and for selecting the desired clones.

Virulence function of the Ustilago maydis sterol carrier protein 2.

The peroxisomal sterol carrier protein 2 (Scp2) of the biotrophic maize pathogen Ustilago maydis was detected in apoplastic fluid, suggesting that it might function as a secreted effector protein. Here we analyze the role of the scp2 gene during plant colonization. We used reverse genetics approaches to delete the scp2 gene, determined stress sensitivity and fatty acid utilization of mutants, demonstrated secretion of Scp2, used quantitative reverse transcription polymerase chain reaction for expression analysis and expressed GFP-Scp2 fusion proteins for protein localization.

The Ustilago maydis repetitive effector Rsp3 blocks the antifungal activity of mannose-binding maize proteins.

To cause disease in maize, the biotrophic fungus Ustilago maydis secretes a large arsenal of effector proteins. Here, we functionally characterize the repetitive effector Rsp3 (repetitive secreted protein 3), which shows length polymorphisms in field isolates and is highly expressed during biotrophic stages. Rsp3 is required for virulence and anthocyanin accumulation.

The Biotrophic Development of Studied by RNA-Seq Analysis.

The maize smut fungus is a model organism for elucidating host colonization strategies of biotrophic fungi. Here, we performed an in depth transcriptional profiling of the entire plant-associated development of wild-type strains. In our analysis, we focused on fungal metabolism, nutritional strategies, secreted effectors, and regulatory networks.

Ustilago maydis effectors and their impact on virulence.

Biotrophic fungal plant pathogens establish an intimate relationship with their host to support the infection process. Central to this strategy is the secretion of a range of protein effectors that enable the pathogen to evade plant immune defences and modulate host metabolism to meet its needs. In this Review, using the smut fungus Ustilago maydis as an example, we discuss new insights into the effector repertoire of smut fungi that have been gained from comparative genomics and discuss the molecular mechanisms by which U.

Genome editing in Ustilago maydis using the CRISPR-Cas system.

This communication describes the establishment of the type II bacterial CRISPR-Cas9 system to efficiently disrupt target genes in the fungal maize pathogen Ustilago maydis. A single step transformation of a self-replicating plasmid constitutively expressing the U. maydis codon-optimized cas9 gene and a suitable sgRNA under control of the U.

Experimental approaches to investigate effector translocation into host cells in the Ustilago maydis/maize pathosystem.

The fungus Ustilago maydis is a pathogen that establishes a biotrophic interaction with Zea mays. The interaction with the plant host is largely governed by more than 300 novel, secreted protein effectors, of which only four have been functionally characterized. Prerequisite to examine effector function is to know where effectors reside after secretion.

Fungal effectors and plant susceptibility.

Plants can be colonized by fungi that have adopted highly diverse lifestyles, ranging from symbiotic to necrotrophic. Colonization is governed in all systems by hundreds of secreted fungal effector molecules. These effectors suppress plant defense responses and modulate plant physiology to accommodate fungal invaders and provide them with nutrients.

Internalization of Near-Infrared Fluorescently Labeled Activatable Cell-Penetrating Peptide and of Proteins into Human Fibrosarcoma Cell Line HT-1080.

The internalization of near-infrared fluorescently labeled cargos into living cells and tissues allows a highly sensitive detection without interference from skin, porphins or other fluorescent cell and tissue compounds. In this study, the uptake of labeled bovine serum albumin and an antibody, into fibrosarcoma (HT-1080) cells was triggered by the formation of non-covalent complexes with different cell-penetrating peptides; uptake efficiency and intracellular localization were determined. To improve selectivity of internalization into tumor cells, a fluorescent activatable cell-penetrating peptide (ACPP) was synthesized and functionally characterized.

Cell penetration: scope and limitations by the application of cell-penetrating peptides.

The penetration of polar or badly soluble compounds through a cell membrane into live cells requires mechanical support or chemical helpers. Cell-penetrating peptides (CPPs) are very promising chemical helpers. Because of their low cytotoxicity and final degradation to amino acids, they are particularly favored in in vivo studies and for clinical applications.

The guiltless guilty: trauma-related guilt and psychopathology in former Ugandan child soldiers.

Child soldiers often experience complex trauma as victims and perpetrators, and feelings of guilt may affect their psychological health. The relationship between the children's traumatic experiences as victims or perpetrators, their perception of themselves as victim or perpetrator, guilt and psychopathology were investigated: of the 330 former child soldiers interviewed, 50.8 % perceived themselves as victims and 19.

Relationships between Cargo, Cell Penetrating Peptides and Cell Type for Uptake of Non-Covalent Complexes into Live Cells.

Modulating signaling pathways for research and therapy requires either suppression or expression of selected genes or internalization of proteins such as enzymes, antibodies, nucleotide binding proteins or substrates including nucleoside phosphates and enzyme inhibitors. Peptides, proteins and nucleotides are transported by fusing or conjugating them to cell penetrating peptides or by formation of non-covalent complexes. The latter is often preferred because of easy handling, uptake efficiency and auto-release of cargo into the live cell.
