The European LeukemiaNet MDS (EUMDS) registry is collecting data of myelodysplastic syndrome (MDS) patients belonging to the IPSS low or intermediate-1 category, newly diagnosed by local cytologists. The diagnosis of MDS can be challenging, and some data report inter-observer variability with regard to the assessment of the MDS subtype. In order to ensure that correct diagnoses were made by the participating centres, blood and bone marrow slides of 10% of the first 1000 patients were reviewed by an 11-person panel of cytomorphologists...

Malignant lymphomas represent one of the most important problems of modern medicine, with a constant increase in the last decades, becoming the most frequent tumor among young people. Sinonasal localization is a particular site of malignant lymphomas, representing the second most frequent among ear, nose and throat (ENT) tumors. In this paper, authors present the clinical, diagnostic and therapeutic aspects of a malignant sinonasal lymphoma, which despite an aggressive histological subtype and important regional extension had a favorable clinical outcome...

The pleomorphic adenoma is the most frequently encountered tumor of the salivary glands, representing between 45% and 75% of the total number of the tumors of the salivary glands. According to the literature, there are many studies on the immunohistochemical aspects of the myoepithelial cells, present in the pleomorphic adenoma of the salivary gland. A big diversity of mono and polyclonal antibodies, such as the cytokeratins, muscular proteins and other markers, has been used. In our study, we investigated the immunohistochemical aspect of bone morphogenetic protein 6 (BMP6) marker concerning 15 cases of pleomorphic adenomas of the salivary glands...

The objective of this review is to summarize results from clinical trials that tested cytotoxic drugs and target strategies for the treatment of platinum resistant (PR) recurrent ovarian cancer (ROC) with particular attention to Phase III and ongoing trials. Areas covered: Since platinum free interval (PFI) represents the most important predictive factor for response to platinum re-treatment in ROC, non-platinum regimens are conventionally considered the most appropriate approaches. Impressive progress has been made in recent decades, resulting in the identification of most effective cytotoxic agents and in the development of new target strategies...

Few studies have been published on the mechanisms of hypoxia response and tolerance in jellyfish, especially with respect to the regulatory mechanism at the molecular level. In this study, Aurelia sp.1, which is frequently found in Chinese coastal waters, was cultivated in a hypoxic system to determine the molecular mechanisms underlying its hypoxic response by studying the physiological activity, gene expression and metabolite contents in the prolyl hydroxylase domain (PHD)-hypoxia inducible factor (HIF) oxygen-sensing system...

Background: In the open-label randomised phase III AURELIA trial, adding bevacizumab to chemotherapy for platinum-resistant ovarian cancer (PROC) significantly improved progression-free survival and response rate versus chemotherapy alone, but not overall survival (OS). We explored the effect of bevacizumab use after disease progression (PD) in patients randomised to chemotherapy alone. Patients and methods: In AURELIA, 361 women with PROC were randomised to chemotherapy alone or with bevacizumab...

The most performing techniques enabling early diagnosis of infectious diseases rely on nucleic acid detection. Today, because of their high technicality and cost, nucleic acid amplification tests (NAAT) are of benefit only to a small fraction of developing countries population. By reducing costs, simplifying procedures and enabling multiplexing, paper microfluidics has the potential to considerably facilitate their accessibility. However, most of the studies performed in this area have not quit the lab. This letter brings NAAT on paper closer to the field, by using clinical samples and operating in a resource-limited setting...

BACKGROUND: DNA elimination is developmentally programmed in a wide variety of eukaryotes, including unicellular ciliates, and leads to the generation of distinct germline and somatic genomes. The ciliate Paramecium tetraurelia harbors two types of nuclei with different functions and genome structures. The transcriptionally inactive micronucleus contains the complete germline genome, while the somatic macronucleus contains a reduced genome streamlined for gene expression. During development of the somatic macronucleus, the germline genome undergoes massive and reproducible DNA elimination events...

Allergic contact dermatitis is a primarily T-cell-mediated inflammatory skin disease induced by exposure to small molecular-weight haptens, which covalently bind to proteins. The abundance of cutaneous T cells that recognize CD1a antigen-presenting molecules raises the possibility that MHC-independent antigen presentation may be relevant in some hapten-driven immune responses. Here we examine the ability of contact sensitizers to influence CD1-restricted immunity. Exposure of human antigen-presenting cells such as monocyte-derived dendritic cells and THP-1 cells to the prototypical contact sensitizer dinitrochlorobenzene potentiated the response of CD1a- and CD1d-autoreactive T cells, which released a vast array of cytokines in a CD1- and TCR-dependent manner...

In Wilson disease (WD), brain cellular damage is thought to be due to copper deposition. Striatal lesions are the most characteristic lesions found in the brain of patients with neurologic symptoms, as emphasized in the initial reports of S.A.K. Wilson. WD brain lesions can be more diffuse, including in the pons, midbrain, thalamus, dentate nucleus, and, less frequently, corpus callosum and cortex. In rare cases, extensive cortical-subcortical lesions have been reported. Increased cellularity is noted in the lesions due to the proliferation of modified astrocytes named Alzheimer types of glia and specific cells, called Opalski cells, that are characteristic of WD...

PURPOSE: A correlation between breast cancer and thyroid disorders has been described in previous studies. Degraded thyroid hormones are referred to as trace amines. These endogenous amines have the ability to bind to the G-protein-coupled receptor TAAR1 (trace amine-associated receptor) and thereby activate it. TAAR1 is able to modulate the serotonergic and dopaminergic system in the brain and has so far been studied in the neurological field. The following study represents the first investigation of the regulation of TAAR1 in primary breast cancer (no metastases, M0)...

Pediatric high grade glioma (pHGGs), including sus-tentorial and diffuse intrinsic pontine gliomas, are known to have a very dismal prognosis. For instance, even an increased knowledge on molecular biology driving this brain tumor entity, there is no treatment able to cure those patients. Therefore, we were focusing on a translational pathway able to increase the cell resistance to treatment and to reprogram metabolically tumor cells, which are, then, adapting easily to a hypoxic microenvironment. To establish, the crucial role of the hypoxic pathways in pHGGs, we, first, assessed their protein and transcriptomic deregulations in a pediatric cohort of pHGGs and in pHGG's cell lines, cultured in both normoxic and hypoxic conditions...

The technology of display of heterologous proteins on the surface of Bacillus subtilis spores enables use of these structures as carriers of antigens for mucosal vaccination. Currently, there are no technical possibilities to predict whether a designed fusion will be efficiently displayed on the spore surface and how such recombinant spores will interact with cells of the immune system. In this study, we compared four variants of B. subtilis spores presenting a fragment of a FliD protein from Clostridium difficile in fusion with CotB, CotC, CotG or CotZ spore coat proteins...

BACKGROUND: Nab-paclitaxel plus gemcitabine has become a standard treatment regimen in patients with metastatic pancreatic adenocarcinoma; however, retrospective data suggest that gemcitabine might be inefficient in 50-60% of patients and thus not an optimum regimen in combination with nab-paclitaxel. We did a phase 2 trial to assess the activity and safety of a new regimen of nab-paclitaxel plus simplified leucovorin and fluorouracil. METHODS: We did a non-comparative, multicentre, open-label, randomised phase 2 trial in 15 hospitals and institutions in France...

Self-powered photodetectors (PDs) have long been realized by utilizing photovoltaic effect and their performances can be effectively enhanced by introducing the piezo-phototronic effect. Recently, a novel pyro-phototronic effect is invented as an alternative approach for performance enhancement of self-powered PDs. Here, a self-powered organic/inorganic PD is demonstrated and the influences of externally applied strain on the pyro-phototronic and the photovoltaic effects are thoroughly investigated. Under 325 nm 2...
