BACKGROUND: The plasminogen activator system plays a key role in ovarian cancer (OC) tumor progression. The plasminogen activator inhibitor type 1 (PAI-1) and the recently identified PAI-1 RNA binding protein 1 (PAI-RBP1) are primary regulators of plasminogen activation and thus are putative biomarkers for OC progression. METHODS: One hundred fifty six OC patients were analyzed to identify the presence of PAI-1 and PAI-RBP1 and subsequently correlated to clinicopathological parameters...

This work shows the capability of Resonance Ionization Mass Spectrometry (RIMS) for the determination of (99g)Tc at the ultra-trace level. The characterization of the prepared samples by X-Ray Photoelectron Spectroscopy (XPS) and optimization of the RIMS setup for this purpose as well as the application of the RIMS method to a soil sample are presented. (97)Tc was used as a tracer isotope to determine the amount of (99g)Tc in a soil sample with RIMS. With 8.8 · 10(10) atoms (97)Tc as tracer, the concentration of (99g)Tc amounts to 1...

Obesity is associated with chronic, low-grade inflammation, which can disrupt homeostasis within tissue microenvironments. Given the correlation between obesity and relative risk of death from cancer, we investigated whether obesity-associated inflammation promotes metastatic progression. We demonstrate that obesity causes lung neutrophilia in otherwise normal mice, which is further exacerbated by the presence of a primary tumour. The increase in lung neutrophils translates to increased breast cancer metastasis to this site, in a GM-CSF- and IL5-dependent manner...

The epidermis is a self-renewing tissue. The balance between proliferation and differentiation processes is tightly regulated to ensure the maintenance of the stem cell (SC) population in the epidermis during life. Aging and cancer may be considered related endpoints of accumulating damages within epidermal self-renewing compartment. p16(INK4a) is a potent inhibitor of the G1/S-phase transition of the cell cycle. p16(INK4a) governs the processes of SC self-renewal in several tissues and its deregulation may result in aging or tumor development...

In classical statistics, much thought has been put into experimental design and data collection. In the high-dimensional setting, however, experimental design has been less of a focus. In this paper, we stress the importance of collecting multiple replicates for each subject in this setting. We consider learning the structure of a graphical model with latent variables, under the assumption that these variables take a constant value across replicates within each subject. By collecting multiple replicates for each subject, we are able to estimate the conditional dependence relationships among the observed variables given the latent variables...

In social interactions, we often need to quickly infer why other people do what they do. More often than not, we infer that behavior is a result of personality rather than circumstances. It is unclear how the tendency itself may contribute to psychopathology and interpersonal dysfunction. Borderline personality disorder (BPD) is characterized by severe interpersonal dysfunction. Here, we investigated if this dysfunction is related to the tendency to over-attribute behaviors to personality traits. Healthy controls and patients with BPD judged positive and negative behaviors presented within a situational constraint during functional magnetic resonance imaging...

Considering that tumor development is generally multifactorial, therapy with a combination of agents capable of potentiating cytotoxic effects is promising. In this study, we co-encapsulated C6 ceramide (0.35%) and paclitaxel (0.50%) in micro and nanoemulsions containing tributyrin (a butyric acid pro-drug included for potentiation of cytotoxicity), and compared their ability to co-localize the drugs in viable skin layers. The nanoemulsion delivered 2- and 2.4-fold more paclitaxel into viable skin layers of porcine skin in vitro at 4 and 8h post-application than the microemulsion, and 1...

Opicapone is a novel catechol-O-methyltransferase (COMT) inhibitor that emerged to fulfil the need of a safer and more efficacious COMT inhibitor. The present study was carried out in order to assess and compare the pharmacokinetics and pharmacodynamics (COMT inhibition) of opicapone after single and multiple oral administrations (30 mg/kg) to Wistar rats. For this purpose, at predefined time points up to 72 h post-dosing, blood, liver and kidneys were collected and, then, the concentrations of opicapone and its active metabolite (BIA 9-1079) were determined in plasma and in liver and kidney tissues, as well as the erythrocyte, liver and kidney COMT activity...

BACKGROUND: Sialic acid-binding immunoglobulin-like lectin (Siglec)-8 is a cell-surface protein expressed selectively on human eosinophils, mast cells, and basophils, making it an ideal target for the treatment of diseases involving these cell types. However, the effective delivery of therapeutic agents to these cells requires an understanding of the dynamics of Siglec-8 surface expression. OBJECTIVE: To determine whether Siglec-8 is endocytosed in human eosinophils and malignant mast cells, identify mechanisms underlying its endocytosis, and demonstrate whether a toxin can be targeted to Siglec-8-bearing cells to kill these cells...

Human dirofilariosis is currently considered to be an emerging zoonosis of Central Europe with climate change and globalization playing a key role in its spreading. Additionally, the occurrence of Dirofilaria spp. is strongly subject to a certain number of microfilaremic dogs and the presence of the mosquito vectors. Both conditions are fulfilled in Slovakia. The first human case of autochthonous dirofilariosis in Slovakia was diagnosed in 2007, 2 years after the infection had been observed in the Slovak dog population...

Training of young surgeons in total hip arthroplasty (THA) is crucial, but might affect operative time and outcome especially in minimally invasive (MIS) THA. We asked whether the learning curve of orthopaedic residents trained on MIS THA has an impact on (1) operative time (2) complication rates and (3) early postoperative outcome. In a retrospective analysis of over 1000 MIS THAs from our institutional joint registry, operative time, complication rates, patient reported outcome measures (Western Ontario and McMaster Universities Arthritis Index [WOMAC] and Euro-Qol 5D-5L [EQ-5D]) within the first year and responder rates for positive outcome as defined by the Outcome Measures in Rheumatology and Osteoarthritis Research Society International consensus responder (OMERACT-OARSI) criteria were compared between trainee and senior surgeons...

Chagas disease cardiomyopathy is a parasite-driven inflammatory disease to which there are no effective treatments. Here we evaluated the therapeutic potential of N,N-dimethylsphingosine(DMS), which blocks the production of sphingosine-1-phosphate(S1P), a mediator of cellular events during inflammatory responses, in a model of chronic Chagas disease cardiomyopathy. DMS-treated, Trypanosoma cruzi-infected mice had a marked reduction of cardiac inflammation, fibrosis and galectin-3 expression when compared to controls...
