Malicious Mites- in Raccoon Dogs () in Schleswig-Holstein, Germany.

Sarcoptic mange was detected in five free-ranging raccoon dogs () in the federal state of Schleswig-Holstein, Germany, during a health assessment study of invasive species, including raccoon dogs, carried out between 2021 and 2022. Four raccoon dogs showed severe lesions, including extensive alopecia with thickening and hyperpigmentation of the skin (lichenification). The fifth animal was less affected, showing only thinning of the hair coat in multiple body locations.

Identification of the novel potential pathogen Trueperella pecoris with interspecies significance by LAMP diagnostics.

Trueperella pecoris was described as a new species of the genus Trueperella in 2021 and might be pathogenic to various animal species. However, the lack of a suitable diagnostic test system stands in the way of epidemiological surveys to clarify possible causalities. In this study, a Loop-mediated Isothermal Amplification (LAMP) assay was developed and validated that was highly specific for T.

Corynebacterium rouxii, a recently described member of the C. diphtheriae group isolated from three dogs with ulcerative skin lesions.

Corynebacterium (C.) diphtheriae is one of the two etiological pathogens for human diphtheria with significant morbidity and mortality. Recently, members of its biovar Belfanti have been described as two novel species, C.

Pain in survivors of Ewing sarcoma: Prevalence, associated factors and prediction of recurrence.

Background: While the prognosis of patients with Ewing sarcoma (EwS) is improving, little is known about the frequency of pain and its risk factors in survivors of EwS. This study aims to analyse the prevalence and risk factors of pain and its predictive value for recurrence.

Patients And Methods: In patients with remission after treatment of EwS, frequency and characteristics of pain within the first 5 years of follow up were assessed retrospectively.

Quality of Survivorship in a Rare Disease: Clinicofunctional Outcome and Physical Activity in an Observational Cohort Study of 618 Long-Term Survivors of Ewing Sarcoma.

Purpose Significantly improved survival rates in patients with Ewing sarcoma have raised interest in accessing the quality of long-term survivorship. In this study, subjective and objective measurement tools, preclassified as physical or mental scores, were used to assess clinicofunctional outcome and physical activity after intensive bone tumor treatment. Methods Long-term outcome of 618 survivors from consecutive Ewing sarcoma trials was assessed by the Toronto Extremity Salvage Score, Short-Form Health Survey (SF-36), Brief Symptom Inventory (BSI), and Rosenberg Self-Esteem Scale questionnaires and by the accelerometric StepWatch 3 Activity Monitor.

The role of the galU gene of uropathogenic Escherichia coli in modulating macrophage TNF-α response.

Uropathogenic Escherichia coli (UPEC) are the major cause of urinary tract infections (UTI). These bacteria are equipped with an arsenal of virulence factors, such as siderophores and adhesins enabling UPECs to sufficiently colonize the urinary tract of humans and animals. Such virulence factors manipulate and impair the recognition of UPECs by the host's innate immune system.

Injectable Bone Substitute Based on β-TCP Combined With a Hyaluronan-Containing Hydrogel Contributes to Regeneration of a Critical Bone Size Defect Towards Restitutio ad Integrum.

In the present in vivo study, the regenerative potential of a new injectable bone substitute (IBS) composed of beta-tricalcium phosphate (β-TCP) and hyaluronan was tested in a rabbit distal femoral condyle model. To achieve this, 2 defects of 6 mm in diameter and 10 mm in length were drilled into each femur condyle in a total of 12 animals. For each animal, 1 hole was filled with the substitute material, and the other was left empty to serve as the control.

The salmochelin receptor IroN itself, but not salmochelin-mediated iron uptake promotes biofilm formation in extraintestinal pathogenic Escherichia coli (ExPEC).

The key to success of extraintestinal pathogenic Escherichia coli (ExPEC) to colonize niches outside the intestinal tract and to establish infection is the coordinated action of numerous virulence and fitness factors. Intense research revealed not only an arsenal of unique virulence determinants with specific action, but also the multi-functionality of single elements. Especially iron uptake systems of ExPEC proved to be of prime importance.

Lipoate-Protein Ligase and Octanoyltransferase Are Essential for Protein Lipoylation in Mitochondria of Arabidopsis.

Prosthetic lipoyl groups are required for the function of several essential multienzyme complexes, such as pyruvate dehydrogenase (PDH), α-ketoglutarate dehydrogenase (KGDH), and the glycine cleavage system (glycine decarboxylase [GDC]). How these proteins are lipoylated has been extensively studied in prokaryotes and yeast (Saccharomyces cerevisiae), but little is known for plants. We earlier reported that mitochondrial fatty acid synthesis by ketoacyl-acyl carrier protein synthase is not vital for protein lipoylation in Arabidopsis (Arabidopsis thaliana) and does not play a significant role in roots.

Effect of a β-TCP collagen composite bone substitute on healing of drilled bone voids in the distal femoral condyle of rabbits.

In this study, we tested the performance and biocompatibility of a composite of β-tricalcium phosphate (β-TCP) to collagen as a bone void filler (Cerasorb(®) Ortho Foam) in a rabbit distal femoral condyle model. β-TCP is a completely resorbable synthetic calcium phosphate and the addition of a collagen matrix couples the osteoconductive effects of the two components. Furthermore, the malleable properties of the implant material during surgical applications for shape control will be enhanced.

Molecular analysis of a novel Toll/interleukin-1 receptor (TIR)-domain containing virulence protein of Y. pseudotuberculosis among Far East scarlet-like fever serotype I strains.

Pathogenicity of Yersinia pseudotuberculosis is determined by an arsenal of virulence factors. Particularly, the Yersinia outer proteins (Yops) and the Type III secretion system (T3SS) encoded on the pYV virulence plasmid are required for Yersinia pathogenicity. A specific group of Y.

From endoplasmic reticulum to mitochondria: absence of the Arabidopsis ATP antiporter endoplasmic Reticulum Adenylate Transporter1 perturbs photorespiration.

The carrier Endoplasmic Reticulum Adenylate Transporter1 (ER-ANT1) resides in the endoplasmic reticulum (ER) membrane and acts as an ATP/ADP antiporter. Mutant plants lacking ER-ANT1 exhibit a dwarf phenotype and their seeds contain reduced protein and lipid contents. In this study, we describe a further surprising metabolic peculiarity of the er-ant1 mutants.

Metaphyseal bone formation induced by a new injectable β-TCP-based bone substitute: a controlled study in rabbits.

Purpose: Adequate filling of bone defects still poses a challenge in every day clinical work. As many bone defects are irregularly shaped the need for appropriate scaffolds reaching the complete defect surface are great. The purpose of this pre-clinical pilot study was to investigate the handling, biocompatibility, biodegradation and osteoconductivity of a new pasty bone substitute (pure phase β-TCP, hyaluronic acid, methylcellulose) in bone tissue.

First multi-epitope subunit vaccine against extraintestinal pathogenic Escherichia coli delivered by a bacterial type-3 secretion system (T3SS).

Infections due to extraintestinal pathogenic E. coli (ExPEC) are very common in humans as well as in animals. In humans ExPEC infections include urinary tract infections (UTI), septicemia, and wound infections, which result in significant morbidity, mortality, and substantial healthcare costs.

Hip transposition as a limb salvage procedure following the resection of periacetabular tumors.

Background And Objectives: One of the most difficult problems in tumor surgery is the treatment of pelvic tumors, particularly those in the periacetabular region. This retrospective study serves to analyze clinical and functional outcome of the new surgical technique of hip transposition.

Patients And Methods: Sixty-two patients were analyzed (chondrosarcoma 15, Ewing's sarcoma or PNET 26, osteosarcoma 14, synovial cell sarcoma 2, others 5) and clinical, oncological, and functional outcome were evaluated.

Arabidopsis nucleoside hydrolases involved in intracellular and extracellular degradation of purines.

Recently, the first plant nucleoside hydrolase, NSH1 (former designation URH1), was identified at the molecular level. This enzyme's highest hydrolysis capacity is for uridine, thereby balancing pyrimidine salvage and catabolism. NSH1 was found to be less efficient in the hydrolysis of further nucleosides.

Influence of β-tricalcium phosphate granule size and morphology on tissue reaction in vivo.

In this study the tissue reaction to five different β-tricalcium phosphate (β-TCP)-based bone substitute materials differing only in size, shape and porosity was analyzed over 60 days, at 3, 10, 15, 30 and 60 days after implantation. Using the subcutaneous implantation model in Wistar rats both the inflammatory response within the implantation bed and the resulting vascularization of the biomaterials were qualitatively and quantitatively assessed by means of standard and special histological staining methods. The data from this study showed that all investigated β-TCP bone substitutes induced the formation of multinucleated giant cells.

Prevalence and phylogenetic history of the TcpC virulence determinant in Escherichia coli.

Extraintestinal pathogenic Escherichia coli (ExPECs) possess an armament of virulence factors to colonize and infect the host, such as adhesins, toxins, capsules and iron-uptake systems. Recently, we could identify a novel virulence factor of ExPECs that interferes with the innate immune response of the host by interrupting the NF-κB signaling pathway. This protein named TcpC shows considerable homology to motifs of the Tir domain of Toll-like receptors.

A multiepitope subunit vaccine conveys protection against extraintestinal pathogenic Escherichia coli in mice.

Infections due to extraintestinal pathogenic Escherichia coli (ExPEC) are common in humans and animals and include urinary tract infections (from uropathogenic E. coli [UPEC]), septicemia, and wound infections. These infections result in significant morbidity and mortality and in high health care costs.

Cell-Laden and Cell-Free Matrix-Induced Chondrogenesis versus Microfracture for the Treatment of Articular Cartilage Defects: A Histological and Biomechanical Study in Sheep.

Objective: The aim of this study was to evaluate the regenerative potential of cell-laden and cell-free collagen matrices in comparison to microfracture treatment applied to full-thickness chondral defects in an ovine model.

Methods: Animals (n = 30) were randomized into 5 treatment groups, and 7-mm full-cartilage-thickness defects were set at the trochlea and medial condyle of both knee joints and treated as follows: 2 scaffolds in comparison (collagen I/III, Chondro-Gide(®); collagen II, Chondrocell(®)) for covering microfractured defects (autologous matrix-induced chondrogenesis), both scaffolds colonized in vitro with autologous chondrocytes (matrix-associated chondrocyte transplantation), or scaffold-free microfracture technique. One year after surgery, cartilage lesions were biomechanically (indentation test), histologically (O'Driscoll score), and immunohistochemically (collagen type I and II staining) evaluated.

Physical activity and childhood cancer.

This review provides a survey of studies investigating physical activity and exercise interventions in patients during tumor treatment and survivors of childhood cancer. PubMed and Medline databases were searched using relevant terms. References of selected papers were tracked.

Level of activity in children undergoing cancer treatment.

Background: The diagnosis of cancer bears severe implications for pediatric patients. One immense restriction consists in a reduced level of activity due to different factors. Physical activity affects various aspects of development and can be regarded as an essential part of a child's life.

Role of intraspecies recombination in the spread of pathogenicity islands within the Escherichia coli species.

Horizontal gene transfer is a key step in the evolution of bacterial pathogens. Besides phages and plasmids, pathogenicity islands (PAIs) are subjected to horizontal transfer. The transfer mechanisms of PAIs within a certain bacterial species or between different species are still not well understood.

Antigen-dependent monophasic or recurrent autoimmune uveitis in rats.

Experimental autoimmune uveitis (EAU) in the Lewis rat has been regarded as an acute and monophasic disease. Uveitis can be induced by immunization with retinal soluble antigen (S-Ag), interphotoreceptor retinoid-binding protein (IRBP) or their peptide derivatives (PDSAg from S-Ag and R14 from IRBP) in CFA as well as by the transfer of activated, antigen-specific T cells. Previously, it has been shown that adoptively transferred, IRBP peptide-specific, but not S-Ag peptide-specific T cells can induce relapsing uveitis in rats.
