a new member of the Yersineacea family has the characteristics of a human pathogen.

(heterotypic synonym: "") is a facultative anaerobic, newly described Gram-negative rod and belongs to the Yersineacea family. Here, we report the case of a 19-month-old female infant patient who presented to the emergency unit with somnolence and fever. was isolated from a positive blood culture, taken via an implanted Broviac catheter, proving a bloodstream infection by the pathogen.

Molecular epidemiology of enterically colonizing with resistance against third-generation cephalosporins isolated from stool samples of European soldiers with concomitant diarrhea on deployment in Western African Mali.

Extended spectrum beta-lactamases (ESBL) are frequently found in Enterobacterales isolates from Western Africa. However, information on the molecular epidemiology of regional ESBL-positive Enterobacterales strains is scarce. In order to provide epidemiological information, ESBL-positive isolates from stool samples of European soldiers with diarrhea deployed to a field camp in Mali were subjected to whole-genome sequencing (Illumina MiSeq and Oxford Nanopore MinION) and antimicrobial susceptibility testing.

Establishment of a novel method to assess MEK1/2 inhibition in PBMCs for clinical drug development.

The Raf/MEK/ERK signaling pathway plays a key role in regulating cellular proliferation, differentiation, apoptosis, cytokine production, and immune responses. However, it is also involved in diseases such as cancer, and numerous viruses rely on an active Raf/MEK/ERK pathway for propagation. This pathway, and particularly MEK1/2, are therefore promising therapeutic targets.

The German EMPATHIC-30 Questionnaire Showed Reliability and Convergent Validity for Use in an Intermediary/General Pediatric Cardiology Unit: A Psychometric Evaluation.

Background: Family-Centered Care is a useful framework for improving care for hospitalized children with congenital heart disease. The EMpowerment of PArents in THe Intensive Care-30 (EMPATHIC-30) questionnaire is a widely accepted tool to measure parental satisfaction with Family-Centered Care. Psychometric properties of the EMPATHIC-30 have been evaluated in neonatal and pediatric intensive care units, but not in pediatric cardiac care units.

Evaluation of Absorbent Versus Conventional Wound Dressing.

Background: Lower-limb endoprosthetic operations and spinal operations are among the more common types of orthopedic procedures. Postoperative woundhealing disturbances and infections can lead to longer periods of hospital stay and recovery as well as to higher morbidity and mortality.

Methods: 209 patients who had been judged to have an indication for a primary knee or hip endoprosthesis or for a primary spinal operation were included in this randomized trial (ClinicalTrials.

Differential expression of vascular endothelial growth factor A, its receptors VEGFR-1, -2, and -3 and co-receptors neuropilin-1 and -2 does not predict bevacizumab response in human astrocytomas.

Background: A major hallmark of malignant progression in human astrocytomas is the formation of new blood vessels. Antiangiogenic therapy using the anti-vascular endothelial growth factor (VEGF)-antibody bevacizumab leads to increased progression-free survival in glioblastoma patients but does not influence their overall survival. To date, it is unclear why antiangiogenic therapy fails in many glioblastoma patients, while a small subpopulation profits considerably from this treatment.

Clinical trial to evaluate the performance of a flexible self-adherent absorbent dressing coated with a soft silicone layer compared to a standard wound dressing after orthopedic or spinal surgery: study protocol for a randomized controlled trial.

Background: Postoperative wound infection is a preventable risk. One potential postoperative complication is blistering, which leads to increased pain, delayed healing, and higher care costs. The incidence of wound blisters has been reported to be between 6 and 24%.

The scent of royalty: a p450 gene signals reproductive status in a social insect.

Cooperation requires communication; this applies to animals and humans alike. The main communication means differ between taxa and social insects (ants, termites, and some bees and wasps) lack the cognitive abilities of most social vertebrates. Central to the regulation of the reproductive harmony in insect societies is the production of a royalty scent which signals the fertility status of the reproducing queen to the nonreproducing workers.

Neonatal lymph node stromal cells drive myelodendritic lineage cells into a distinct population of CX3CR1+CD11b+F4/80+ regulatory macrophages in mice.

Beyond providing a scaffold for immune cells, recent studies indicate that lymph node stromal cells provide potent regulatory capacities that affect the quality of adaptive immune responses. In this study, we provide evidence that neonatal lymph node stromal cells (nnLNSCs) consistently promote the differentiation of macrophage dendritic cell progenitors as well as mature and immature dendritic cells into a distinct population of CX3CR1(+) CD11b(+)F4/80(+) regulatory macrophages (regMΦ). These cells possess remarkably low levels of T cell costimulatory molecules as well as MHC class II molecules.

Molting dynamics and juvenile hormone titer profiles in the nymphal stages of a lower termite, Cryptotermes secundus (Kalotermitidae)--signatures of developmental plasticity.

Termites are social cockroaches and this sociality is founded on a high plasticity during development. Three molting types (progressive, stationary and regressive molts) are fundamental to achieve plasticity during alate/sexual development, and they make termites a major challenge to any model on endocrine regulation in insect development. As the endocrine signatures underpinning this plasticity are barely understood, we studied the developmental dynamics and their underlying juvenile hormone (JH) titers in a wood-dwelling termite, Cryptotermes secundus, which is characterized by an ancestral life style of living in dead wood and individuals being totipotent in development.

Afferent lymph-derived T cells and DCs use different chemokine receptor CCR7-dependent routes for entry into the lymph node and intranodal migration.

Little is known about the molecular mechanisms that determine the entry into the lymph node and intranodal positioning of lymph-derived cells. By injecting cells directly into afferent lymph vessels of popliteal lymph nodes, we demonstrate that lymph-derived T cells entered lymph-node parenchyma mainly from peripheral medullary sinuses, whereas dendritic cells (DCs) transmigrated through the floor of the subcapsular sinus on the afferent side. Transmigrating DCs induced local changes that allowed the concomitant entry of T cells at these sites.

Tolerance induction towards cardiac allografts under costimulation blockade is impaired in CCR7-deficient animals but can be restored by adoptive transfer of syngeneic plasmacytoid dendritic cells.

Deficiency of transplant recipients for the chemokine receptor CCR7 was originally described to slightly increase the survival time of vascularized solid organ grafts, probably due to a reduced priming of alloreactive T cells. Using a model of allotolerance induction by donor-specific splenocyte transfusion (DST) in combination with anti-CD40L mAb-mediated costimulation blockade (CSB), we show here a striking failure of CCR7-deficient (CCR7(-/-) ) recipients to tolerate cardiac allografts. Furthermore, in addition to the recently described lack of Treg, CCR7(-/-) mice were found to harbor significantly reduced numbers of plasmacytoid dendritic cells (pDCs) within peripheral as well as mesenteric lymph nodes (LNs), but not the bone marrow or spleen.

Endocrine signatures underlying plasticity in postembryonic development of a lower termite, Cryptotermes secundus (Kalotermitidae).

Wood-dwelling termites are characterized by an extremely high and unique developmental flexibility that allows workers, which are immatures, to explore all caste options. The endocrine signatures underlying this flexibility are only vaguely understood. We determined juvenile hormone (JH) and ecdysteroid hemolymph titers during postembryonic development and in terminal instars of the drywood termite Cryptotermes secundus using field and laboratory colonies.

Chemokine receptor CCR7 contributes to a rapid and efficient clearance of lytic murine gamma-herpes virus 68 from the lung, whereas bronchus-associated lymphoid tissue harbors virus during latency.

Murine gamma-herpes virus 68 is a natural rodent pathogen closely related to the human gamma-herpes viruses Kaposi's sarcoma-associated herpes virus and EBV. By intranasally infecting wild-type and CCR7-deficient mice, we investigated whether CCR7 is necessary for viral clearance from the lung and the establishment of latency. We found during the lytic phase of infection that inflammation in lungs of CCR7(-/-) mice was more severe and viral load significantly higher compared with wild-type littermates.

A gene necessary for reproductive suppression in termites.

A major transition in evolution is the origin of a division between reproduction and work among individuals. Nowhere is this divide more striking than in social insects, where workers rarely produce offspring even though they are often capable of reproduction should the queen or king die. The molecular mechanisms that control worker reproduction remain largely unknown.

Scent of a queen-cuticular hydrocarbons specific for female reproductives in lower termites.

In social insects, it is assumed that signals of the queen inform nestmates about her reproductive status. Thus, workers forego their own reproduction if the queen signals high fertility. In hemimetabolous termites, little is known about reproductive inhibition, but evidence exists for a royal-pair control.

Development of a database of patients supported by ventricular assist devices.

An increase in the number of patients with end stage heart failure is leading to increased use of ventricular assist devices (VAD). However, sometimes the optimal time point for implantation of left ventricular or biventricular support remains unclear. Data analysis using an electronic database may help to make the decision making process more precise and thus improve outcome.
