Abstract We report a case of an 82-year-old man with renal cell carcinoma who developed a cardiac metastasis within the interventricular septum. He had been under watchful waiting for indolent metastatic renal cell carcinoma for many years before developing symptoms consistent with heart failure. At this time, a 44 mm interventricular septal mass, consistent with a cardiac metastasis, was identified as the cause of his symptoms. Pazopanib was initiated which led to both a clinical and radiological response. More >

Abstract The main goal of this work was the development of photoactive multilayer fi lms. Taking into account that chitosan is a biodegradable, biocompatible, nontoxic, and antibacterial biopolymer, the fabrication of chitosanbased multilayer fi lms can be an interesting pathway to obtain biopolymer-based fi lms in which properties can be combined with a light-responsive material, such as an azobenzene-containing polymer. In particular, the layer-by-layer technique was used for the fabrication of the optically active fi lms consisting of alternating layers of chitosan and an azopolymer. The infl uence of the pH and the number of bilayers More >

Abstract We developed a functional model for a shrub steppe vegetation of the eastern Monte Phytogeographical Province in Río Negro (Argentina) with six stable states and 12 transitions, based on the woody encroachment degree, characteristics of the herbaceous layer and the soil surface, and biological crust cover. Information was obtained from letters of naturalists and travelers along the region since the late eighteenth century, reports of old settlers, and our own research work. On the Monte, different functional groups can be distinguished. Our work focused on the three most conspicuous to analyze the dynamics of the… More >

Abstract Fish is a very important part of the human diet in Amazonia. Near the growing cities, fish populations and individual size have decreased over the past decades. Alternatives to traditional and industrial fishing arise, including fish farming. Strategies to minimize the impact of fish farms on the environment are needed to have a regular and healthy fish supply. This is to avoid a reduction of biodiversity, a depletion of natural resources, and/or the induction of significant changes in the structure and functioning of adjacent ecosystems. Very little research has been performed on management of effluents… More >

Abstract Grasslands are one of the most widespread landscapes worldwide, covering approximately one-fifth of the world’s land surface, where grazing is a common practice. How carbon storage responds to grazing in steppes remains poorly understood. We quantified the effects of grazing on community composition and species diversity, and carbon storage in two typical grasslands of northeastern China, one in Horqin and the other one in Hulunbeier. In both grasslands, grazing did not influence plant species diversity. However, it substantially decreased aboveground carbon by 31% and 54% in Horqin and Hulunbeier, respectively. Fenced and grazing treatments showed More >

Abstract Determining sectors that could be affected by lava flows in volcanic areas is essential for risk mitigation purposes. Traditionally, when adopting methods based on probabilistic numerical simulations, the hazard is assessed by analysing a huge set of simulations of hypothetical events, each characterized by a distinct probability of occurrence based on statistics of historical events. If lateral or eccentric eruptions are also taken into account, simulated lava flows usually start from the nodes of regular grids of potential vents, uniformly covering the study area. In this study, an alternative approach to evaluate flow-type hazard, based More >

Abstract instruction: Introduction: Rapid progress has recently been made in understanding the biology of advanced prostate cancer. This has translated into the development of a number of novel agents to treat metastatic castration-resistant prostate cancer (mCRPC).
instruction: Materials and methods: The relevant literature was retrieved from a search of MEDLINE with appropriate keywords.
instruction: Results: Therapeutic approaches to mCRPC include chemotherapy, hormonal manipulation, immunotherapy and radioisotope therapy. Docetaxel and cabazitaxel are cytotoxic agents which have demonstrated a modest impact on survival. Hormonal manipulation with abiraterone and enzalutamide have also been reported to be beneficial in mCRPC. The radioisotope radium-223 More >

Abstract instruction: Introduction: Chemotherapy, once thought to be toxic and ineffective in men with castration-resistant prostate cancer (CRPC), has a significant impact on survival and quality-of-life in these patients. This article summarizes recent studies performed with two Food and Drug Administration (FDA) approved agents which have improved survival in men with CRPC, docetaxel and cabazitaxel.
instruction: Materials and methods: The literature on cytotoxic chemotherapy for castration-resistant prostate cancer was reviewed. The individual efficacy, mechanisms of chemotherapeutic action, and appropriate disease states of administration were identified. Recent clinical trial results of chemotherapy combined with targeted agents was also reviewed.
instruction:… More >

Abstract instruction: Introduction: Newer approaches to the management of advanced prostate cancer have rapidly evolved. While basic androgen deprivation remains as the first line in newly diagnosed hormone naïve metastatic prostate cancer, the agents used and strategies followed have undergone significant changes. Numerous new agents such as sipuleucel-T, abiraterone, enzalutamide, cabazitaxel and radium-223 have all been approved since 2010 to treat metastatic castration-resistant prostate cancer (CRPC). New imaging techniques to detect advanced disease such as F-18 PET, 11C-choline PET and other modalities are becoming available. The concepts of "bone health" and the management of side effects related… More >

Abstract Introduction: Major kidney stones have traditionally been treated with percutaneous nephrolithotomy. However, retrograde intrarenal surgery (RIRS), which until a few years ago was considered inappropriate for this purpose, is becoming a viable, attractive alternative. The aim of the current study was to assess the efficacy and safety of RIRS combined with holmium laser lithotripsy for the treatment of stones >2 cm in diameter in a large series of patients, reporting complications according to the Clavien-Dindo classification.
Materials and methods: By retrospective analysis, we identified a total of 162 patients who were affected by stones greater than… More >
