A multiantigenic Orf virus-based vaccine efficiently protects hamsters and nonhuman primates against SARS-CoV-2.

Among the common strategies to design next-generation COVID-19 vaccines is broadening the antigenic repertoire thereby aiming to increase efficacy against emerging variants of concern (VoC). This study describes a new Orf virus-based vector (ORFV) platform to design a multiantigenic vaccine targeting SARS-CoV-2 spike and nucleocapsid antigens. Vaccine candidates were engineered, either expressing spike protein (ORFV-S) alone or co-expressing nucleocapsid protein (ORFV-S/N).

A ruthenium catalyst linked to a redox-active ruthenium polypyridine for water oxidation.

Chromophore-catalyst assemblies are interesting benchmark molecules for photocatalysis. We have prepared two examples of these assemblies and characterized their behaviour as catalysts for the water oxidation reaction. In the bimetallic complexes [Ru(tpy)(4,4'-X-bpy)(μ-CN)Ru(bda)(DMSO)](PF) (X = -H (1), -OCH (2), tpy = 2,2':6',2''-terpyridine, bpy = 2,2'-bipyridine, Hbda = 2,2'-bipyridine-6,6'-dicarboxylic acid and DMSO = (CH)SO), a Ru(II)-polypiridine chromophore {Ru(tpy)(4,4'-X-bpy)} is linked by a cyanide bridge to a {Ru(bda)} water oxidation catalyst.

Automated quantification of photoreceptor outer segments in developing and degenerating retinas on microscopy images across scales.

The functionality of photoreceptors, rods, and cones is highly dependent on their outer segments (POS), a cellular compartment containing highly organized membranous structures that generate biochemical signals from incident light. While POS formation and degeneration are qualitatively assessed on microscopy images, reliable methodology for quantitative analyses is still limited. Here, we developed methods to quantify POS (QuaPOS) maturation and quality on retinal sections using automated image analyses.

The process recommendations of the Ethics Section of the German Interdisciplinary Association for Intensive Care and Emergency Medicine (DIVI) for ethically based decision-making in intensive care medicine are intended to create the framework for a structured procedure for seriously ill patients in intensive care. The processes require appropriate structures, e.g.

Robust Molecular Anodes for Electrocatalytic Water Oxidation Based on Electropolymerized Molecular Cu Complexes.

A multistep synthesis of a new tetra-amidate macrocyclic ligand functionalized with alkyl-thiophene moieties, 15,15-bis(6-(thiophen-3-yl)hexyl)-8,13-dihydro-5H-dibenzo[b,h][1,4,7,10]tetraazacyclotridecine-6,7,14,16(15H,17H)-tetraone, H L, is reported. The reaction of the deprotonated ligand, L , and Cu(II) generates the complex [LCu] , that can be further oxidized to Cu(III) with iodine to generate [LCu] . The H L ligand and their Cu complexes have been thoroughly characterized by analytic and spectroscopic techniques (including X-ray Absorption Spectroscopy, XAS).

[Dealing with coercion in intensive care medicine : Recommendations from the Ethics Section of the German Interdisciplinary Association for Intensive Care and Emergency Medicine (DIVI) in collaboration with the Ethics Section of the German Society for Internal Intensive Care and Emergency Medicine (DGIIN)].

The treatment situation in intensive care is characterised by a specific asymmetry in the relationship between patients and the team: Patients are particularly dependent on their environment and often show impaired consciousness and capacity to consent. This facilitates the use of coercion or enables and/or provokes it. The aim of this recommendation is to show ways to recognise patients with their wishes and needs and to integrate them into treatment concepts in the intensive care unit in order to reduce and avoid coercion whenever possible.

A Novel Orf Virus D1701-VrV-Based Dengue Virus (DENV) Vaccine Candidate Expressing HLA-Specific T Cell Epitopes: A Proof-of-Concept Study.

Although dengue virus (DENV) affects almost half of the world's population there are neither preventive treatments nor any long-lasting and protective vaccines available at this time. The complexity of the protective immune response to DENV is still not fully understood. The most advanced vaccine candidates focus specifically on humoral immune responses and the production of virus-neutralizing antibodies.

Safety of anti-TNF agents in patients with compensated cirrhosis: a case-control study.

Background: There is limited data on the use of anti-TNF agents in patients with concomitant cirrhosis. The aim of this study is to assess the safety of anti-TNF agents in patients with compensated cirrhosis who used these medications for the treatment of an underlying rheumatologic condition or IBD.

Methods: Multicenter, retrospective, matched, case-control study.

Heteroleptic Ruthenium(II) Complexes with 2,2'-Bipyridines Having Carbonitriles as Anchoring Groups for ZnO Surfaces: Syntheses, Physicochemical Properties, and Applications in Organic Solar Cells.

Heteroleptic ruthenium (II) complexes were used for sensitizing ZnO surfaces in organic solar cells (OSCs) as mediators with photoactive layers. The complexes [Ru(4,4'-X-bpy)(Mebpy-CN)] (with X = -CH, -OCH and -N(CH); bpy = 2,2'-bipyridine; Mebpy-CN = 4-methyl-2,2'-bipyridine-4'-carbonitrile) were synthesized and studied by analytical and spectroscopical techniques. Spectroscopic, photophysical, and electrochemical properties were tuned by changing the electron-donating ability of the -X substituents at the 4,4'-positions of the bpy ring and rationalized by quantum mechanical calculations.

Novel Heteroleptic Ruthenium(II) Complexes with 2,2'- Bipyridines Containing a Series of Electron-Donor and Electron-Acceptor Substituents in 4,4'-Positions: Syntheses, Characterization, and Application as Sensitizers for ZnO Nanowire-Based Solar Cells.

A novel series of complexes of the formula [Ru(4,4'-X-bpy)(Mebpy-CN)](PF) (X = -CH, -OCH, -N(CH); Mebpy-CN = 4-methyl-2,2'-bipyridine-4'-carbonitrile) have been synthesized and characterized by spectroscopic, electrochemical, and photophysical techniques. Inclusion of the electron-withdrawing substituent -CN at one bpy ligand and different electron-donor groups -X at the 4,4'-positions of the other two bpy ligands produce a fine tuning of physicochemical properties. Redox potentials, electronic absorption maxima, and emission maxima correlate well with Hammett's σ parameters of X.

Afro-Caribbeans Have a Lower Prevalence of Advanced Colon Neoplasia than African-Americans.

Background/aims: The black population in the USA is a heterogeneous group composed of smaller subgroups from different origins. The definition of black in many colorectal cancer (CRC) risk studies is vague, and differences in CRC risk comparing black subpopulations have not been evaluated. The aim of the study is to compare advanced colorectal neoplasia (ACN) between two subgroups of black populations: African-American (AA) and Afro-Caribbean (AC).

Lupus enteritis as the only active manifestation of systemic lupus erythematosus: A case report.

Background: Lupus enteritis is a rare manifestation of systemic lupus erythematosus (SLE). Diagnosis of this condition is difficult, especially in the absence of other symptoms related to active SLE. We present the case of a 25-year-old female with lupus enteritis as the sole initial manifestation of active SLE.

[Decision-making support in Intensive Care to facilitate organ donation : Position paper of the Ethics Section and the Organ Donation and Transplantation Section of the German Interdisciplinary Association of Critical Care and Emergency Medicine (DIVI) in collaboration with the Ethics Section of the German Society of Medical Intensive Care Medicine and Emergency Medicine (DGIIN)].

Background And Challenge: Injuries, especially traumatic brain injury, or specific illnesses and their respective sequelae can result in the demise of the patients afflicted despite all efforts of modern intensive care medicine. If in principle organ donation is an option after a patient's death, intensive therapeutic measures are regularly required in order to maintain the homeostasis of the organs. These measures, however, cannot benefit the patient afflicted anymore-which in turn might lead to an ethical conflict between dignified palliative care for him/her and expanded intensive treatment to facilitate organ donation for others, especially if the patient has opted for the limitation of life-sustaining therapies in an advance directive.

Genomic Characterization of Strain D1701-V () and Development of Novel Sites for Multiple Transgene Expression.

The (ORFV; ) strain D1701 with an attenuated phenotype and excellent immunogenic capacity is successfully used for the generation of recombinant vaccines against different viral infections. Adaption for growth in Vero cells was accompanied by additional major genomic changes resulting in ORFV strain variant D1701-V. In this study, restriction enzyme mapping, blot hybridization and DNA sequencing of the deleted region s (A, AT and D) in comparison to the predecessor strain D1701-B revealed the loss of 7 open reading frames (ORF008, ORF101, ORF102, ORF114, ORF115, ORF116, ORF117).

[Amendment to the documentation of decisions to withhold or withdraw life-sustaining therapies in consideration of wish to donate organs : Recommendation of the Ethics Section and the Organ Donation and Transplantation Section of the German Interdisciplinary Association of Critical Care and Emergency Medicine (DIVI) in collaboration with the Ethics Section of the German Society of Medical Intensive Care Medicine and Emergency Medicine (DGIIN)].

The Ethics Section of the German Interdisciplinary Association of Critical Care and Emergency Medicine (DIVI) recently published a documentation for decisions to withhold or withdraw life-sustaining therapies. The wish to donate organs was not considered explicitly. Therefore the Ethics Section and the Organ Donation and Transplantation Section of the DIVI together with the Ethics Section of the German Society of Medical Intensive Care Medicine and Emergency Medicine worked out a supplementary footnote for the documentation form to address the individual case of a patient's wish to donate organs.

[Management of an elderly patient in the emergency room at the end of life : A medical ethics challenge].

A 94-year-old patient with cardiogenic shock due to myocardial infarction was admitted via the emergency room. A coronary angiography and intensive care were requested. The need for care due to dementia was known.

[Autonomy and welfare in intensive care medicine : Practical approach in difficult situations].

In intensive care units far-reaching decisions are often made at short notice that require the consent of the informed patient. If this is not possible due to the patient's condition, physicians and legal representatives must ascertain the previously expressed or presumed will of the patient and act accordingly. The legal principles are specified in the Patient Advance Directives Act and the Patient Rights Act.
