Petroleum hydrocarbons are one of the primary organic chemicals found in water bodies, and the water-soluble fraction of petroleum (WSFP) may be responsible for much of the toxic effects. In the present study, genotoxicity assays and histopathological analysis of the gills were analyzed for two experimental protocols: 1) Juvenile Centropomus parallelus were exposed to different concentrations of WFSP (0%, 25%, 50% and 75%) for 96h; 2) A second fish group was exposed to 50% WFSP for 168h followed by a post-exposure period for 168h in clean water (recovery)...

Riassunto. I PARP inibitori interferiscono con la riparazione del danno nella singola elica del DNA determinando una progressione del difetto nella doppia elica. In circa il 50% delle pazienti con carcinoma dell'ovaio sieroso di alto grado sono presenti difetti nei meccanismi di ricombinazione omologa, deputati alla riparazione del danno della doppia elica del DNA. L'incapacità di riparare il danno si traduce nella morte cellulare, un processo definito "letalità sintetica". Nella famiglia dei PARP inibitori il niraparib è stato il primo a essere approvato dalla FDA nel trattamento delle pazienti con carcinoma ovarico ricorrente indipendentemente dalla presenza o assenza di mutazioni BRCA...

The main aim of this study was to assess the physicochemical and biological properties of a novel poly(ether ether ketone) (PEEK) composite containing 30%wt natural amorphous silica fibers (NASF). PEEK and NASF powders were previously functionalized by atomization and citric acid in order to enhance adhesion between polymeric matrix and fillers. Then, composites were produced by cold compression molding technique at 350°C for 3h. Materials were characterized by chemical, microstructural, thermophysical, mechanical and cytotoxic analysis...

Natural mortality of Atlantic sturgeon (Acipenser oxyrinchus) has been determined to be low (M = 0.07). Reported herein is the mortality by beach stranding of 11 Atlantic sturgeon in Scot's Bay, part of the inner Bay of Fundy in Nova Scotia, Canada on 22 June 2014. Genetic analyses, histological analysis and age determination were performed to determine origin, maturity stage and age of the stranded Atlantic sturgeon. Microsatellite and mitochondrial DNA analyses indicated that four of the Atlantic sturgeon (2 males and 2 females) were from the Saint John River, NB population, which was designated as threatened by the Committee on the Status of Endangered Wildlife in Canada...

Objective Pulmonary nocardiosis frequently develops as an opportunistic infection in patients with malignant tumor and is treated with steroids. This study was performed to clarify the clinical features of pulmonary nocardiosis in Japan. Methods The patients definitively diagnosed with pulmonary nocardiosis at our hospital between January 1995 and December 2015 were retrospectively investigated. Results Nineteen men and 11 women (30 in total) were diagnosed with pulmonary nocardiosis. Almost all patients were complicated by a non-pulmonary underlying disease, such as malignant tumor or collagen vascular disease, or pulmonary disease, such as chronic obstructive pulmonary disease or interstitial pneumonia, and 13 patients (43...

In a study of a muon-neutrino disappearance at 810 km, the NOvA experiment finds flavor mixing of the atmospheric sector to deviate from maximal (sin^{2}θ_{23}=0.5) by 2.6σ. The result is in tension with the 295-km baseline measurements of T2K, which are consistent with maximal mixing. We propose that θ_{23} is in fact maximal, and that the disagreement is a harbinger of environmentally induced decoherence. The departure from maximal mixing can be accounted for by an energy-independent decoherence of strength Γ=(2...

A brain abscess may result when dental infection reaches the brain through contiguous anatomic cavities such as the maxillary sinus, the ethmoid sinus and the orbital cavity. It is an important complication and should be treated aggressively. Such treatment would include the excision of the etiological factor, drainage and adjuvant antibiotic therapy. The present case concerns a 23-year-old woman who presented at the General Hospital of Nova Iguaçu with complaints of pain in the right side of the face and was diagnosed with acute sinusitis...

This study's aim was to develop and implement an integrative epidemiologic cross-sectional study that allows identifying and characterising exposure pathways of populations living and working on the shores of a contaminated estuarine environment. Population residing in Carrasqueira, located on the Sado estuary with known contaminated areas was compared to another population on a noncontaminated estuary (Vila Nova de Mil Fontes - VNMF), considered a nonexposed population. Simple random samples of individuals were selected in each study population from the National Health Service Lists: 140 individuals were selected in Carrasqueira and 219 in VNMF...

OBJECTIVE: There is a need for the routine monitoring of treated attention-deficit hyperactivity disorder (ADHD) for timely policy making. The objective is to report and assess over a decade the prevalence and incidence of diagnosed ADHD in Canada. METHODS: Administrative linked patient data from the provinces of Manitoba, Ontario, Quebec, and Nova Scotia were obtained from the same sources as the Canadian Chronic Diseases Surveillance Systems to assess the prevalence and incidence of a primary physician diagnosis of ADHD ( ICD-9 and ICD-10 codes: 314, F90...

Severe hemorrhage with necessity of allogeneic blood transfusion is common complication in intensive care unit and is associated with increased morbidity and mortality. Prompt recognition and treatment of bleeding causes becomes essential for the effective control of hemorrhage, rationalizing the use of allogeneic blood components, and in this way, preventing an occurrence of their potential adverse effects. Conventional coagulation tests such as prothrombin time and activated partial thromboplastin time present limitations in predicting bleeding and guiding transfusion therapy in critically ill patients...

Chronic obstructive pulmonary disease (COPD) is a leading cause of death, morbidity, and health-care spending. The Halifax, Nova Scotia-based INSPIRED COPD Outreach Program™ has proved highly beneficial for patients and the health-care system. With direct investment of <$1-million CAD, a pan-Canadian quality improvement collaborative (QIC) supported the spread of INSPIRED to 19 teams in the 10 Canadian provinces contingent upon participation in evaluation. The collaborative evaluation followed a mixed-methods summative approach relying on collated quantitative data, team documents, and surveys sent to core members of the 19 teams...

A neotype of Amphitrite Müller (1771) is established and re-described, using material collected in 2001 from near the type locality on the southwest coast of Iceland. We examined material from Iceland, Nova Scotia and Newfoundland, identified as Pseudopotamilla reniformis, showing scissiparity and commonly found in aggregations within kelp holdfasts or amongst encrusting fauna. By contrast, scissiparity has not been seen in a population recorded as P. reniformis from Wales (broadcast spawning is presumed, Chughtai & Knight-Jones 1988), which bores into limestone and that the present analysis shows to belong to a different species from P...

Recruitment is a key demographic process for population persistence. This paper focuses on barnacle (Semibalanus balanoides) recruitment. In rocky intertidal habitats from the Gulf of St. Lawrence coast of Nova Scotia (Canada), ice scour is common during the winter. At the onset of intertidal barnacle recruitment in early May (after sea ice has fully melted), mostly only adult barnacles and bare substrate are visible at high elevations in wave-exposed habitats. We conducted a multiannual study to investigate if small-scale barnacle recruitment could be predicted from the density of pre-existing adult barnacles...
