Ependymomas of the posterior fossa in adults are relatively rare, represent less than 1% of adult intracranial gliomas. Most of the cases are WHO grade II. Due to their rarity, there are no randomized studies regarding the best management of these tumors. It seems that surgical resection has a major role in their management. Unlike the scenario in children, these tumors can be cured by gross total resection without adjuvant therapy in the majority of cases. Hence, knowing the different surgical approaches, with their pros and cons, is important in order to offer the patient the best treatment...

The purpose of this paper is to interoduce and review the characteristic imaging features of ependymal neoplasms through a comprehensive case-based approach. Illustrated cases highlight both common and uncommon manifestations of CNS-ependymomas. The combination of imaging features, location of the tumor, and patient's demographics often allow the suggestion of ependymoma as a lead entity in the differential diagnosis. However, significant overlap exists between the radiologic characteristics of ependymomas and those of other tumors commonly encountered in the same locations, which can pose a challenge for a definitive diagnosis based on imaging alone...

Lactobacillus rhamnosus DSM 14870 and Lactobacillus gasseri DSM 14869 were previously isolated from the vaginal epithelial cells (VEC) of healthy women and selected for the development of the vaginal EcoVag(®) probiotic capsules. EcoVag(®) was subsequently shown to provide long-term cure and reduce relapse of bacterial vaginosis (BV) as an adjunct to antibiotic therapy. To identify genes potentially involved in probiotic activity, we performed genome sequencing and characterization of the two strains. The complete genome analysis of both strains revealed the presence of genes encoding functions related to adhesion, exopolysaccharide (EPS) biosynthesis, antimicrobial activity, and CRISPR adaptive immunity but absence of antibiotic resistance genes...

Most sulfate-reducing microorganisms (SRM) present in subsurface marine sediments belong to uncultured groups only distantly related to known SRM and it remains unclear how changing geochemical zones and sediment depth influence their community structure. We mapped the community composition and abundance of SRM by amplicon-sequencing and quantifying dsrB, which encodes dissimilatory sulfite reductase subunit beta, in sediment samples covering different vertical geochemical zones ranging from the surface sediment to the deep sulfate-depleted subsurface at four locations in Aarhus Bay, Denmark...

Childhood obesity is associated with renal diseases. Maternal obesity is a risk factor linked to increased adipocytokines and metabolic disorders in the offspring. We therefore studied the impact of maternal obesity on renal-intrinsic insulin and adipocytokine signaling and on renal function and structure. To induce maternal obesity female mice were fed with high-fat diet (HFD) or standard diet (SD, Co) prior to mating, during gestation and throughout lactation. A third group of dams was fed HFD only during lactation (HFD-Lac)...

Polyglutamine (PolyQ) diseases are progressive neurodegenerative disorders caused by both protein- and RNA-mediated toxicities. We previously showed that a peptidyl inhibitor, P3, which binds directly to expanded CAG RNA can inhibit RNA-induced nucleolar stress and suppress RNA-induced neurotoxicity. Here we report a N-acetylated and C-amidated derivative of P3, P3V8, that showed a more than 20-fold increase in its affinity for expanded CAG RNA. The P3V8 peptide also more potently alleviated expanded RNA-induced cytotoxicity in vitro, and suppressed polyQ neurodegeneration in Drosophila with no observed toxic effects...

BACKGROUND: While there is a proven association of upper genital tract Ureaplasma infection during pregnancy with adverse pregnancy outcome, the effect of vaginal Ureaplasma colonization on preterm delivery has been controversially debated. OBJECTIVES: We hypothesized that women with isolation of vaginal U. parvum but not U. urealyticum are at increased risk for spontaneous preterm birth (SPB) compared to women with negative results. METHODS: A vaginal swab taken between 12 and 14 weeks of gestation was analyzed for the presence of Ureaplasma biovars by PCR in 4,330 pregnant women...

Kasper Vadstrup, Flemming Bendtsen
Crohn's disease (CD) and ulcerative colitis (UC) are immunologically-mediated, debilitating conditions resulting from destructive inflammation of the gastrointestinal tract. The pathogenesis of IBD is incompletely understood, but is considered to be the result of an abnormal immune response with a wide range of cell types and proteins involved. Natural Killer Group 2D (NKG2D) is an activating receptor constitutively expressed on human Natural Killer (NK), γδ T, mucosal-associated invariant T (MAIT), CD56⁺ T, and CD8⁺ T cells...

This prospective, noninterventional study is the first phase IV trial designed to evaluate trabectedin in patients with advanced soft tissue sarcoma in real-life clinical practice across Europe. To be included in the study, patients must have received more than or equal to one cycle of trabectedin and be currently on treatment. The primary endpoint was progression-free survival as defined by investigators. The secondary endpoints included objective response rate, disease control rate, time to progression and the growth modulation index (GMI), overall survival, and an assessment of the cancer-related symptoms and safety...

GU-AG consensus sequences are used for intron recognition in the majority of cases of pre-mRNA splicing in eukaryotes. Mutations at splice junctions often cause exon skipping, short deletions, or insertions in the mature mRNA, underlying one common molecular mechanism of genetic diseases. Using N-ethyl-N-nitrosourea, a novel recessive mutation named seal was produced, associated with fragile bones and susceptibility to fractures (spine and limbs). A single nucleotide transversion (T → A) at the second position of intron 36 of the Col1a1 gene, encoding the type I collagen, α1 chain, was responsible for the phenotype...

Collagen is a main component of the extracellular matrix. It is often used in medical applications to support tissue regeneration, hemostasis, or wound healing. Due to different sources of collagen, the properties and performance of available products can vary significantly. In this in vitro study, a comparison of seven different collagen matrices derived from bovine, equine, and porcine sources was performed. As performance indicators, the scaffold function for fibroblasts and platelet aggregation were used...

There is an increased need to develop novel alternative approaches to the two-year rodent bioassay for the carcinogenicity assessment of substances where the rodent bioassay is still a basic requirement, as well as for those substances where animal use is banned or limited or where information gaps are identified within legislation. The current progress in this area was addressed in a EURL ECVAM- ESTIV workshop held in October 2016, in Juan les Pins. A number of initiatives were presented and discussed, including data-driven, technology-driven and pathway-driven approaches...

OBJECTIVE: Retroperitoneal sarcomas (RPSs) are rare cancers with some variability in clinical and histopathological presentation. In Germany, general treatment strategies of retroperitoneal sarcoma are unknown since centralized registries do not exist. The objective of this survey was to access the medical care of RPS patients in Germany. METHODS: In cooperation with the German Society of General and Visceral surgery, the German Interdisciplinary Sarcoma Study Group and the patient advocacy group Das Lebenshaus we designed an online survey assessing diagnostic and treatment strategies (e...

BACKGROUND: As many patients with unipolar depression do not respond sufficiently to initial antidepressant monotherapy, a dose increase of the current administered antidepressant (dose escalation, high-dose treatment) is frequently carried out as next treatment measure. METHODS: We conducted a meta-analysis which included all double-blind randomized controlled trials (RCTs) comparing a dose increase of antidepressants directly to continuation of standard-dose treatment in unipolar depressive patients who were non- responders to standard-dose pharmacotherapy...
