Anti-cancer potential of Fasciola hepatica extracts

Fascioliasis is a food borne disease caused by infection with a liver fluke termed Fasciola (F.) hepatica. Fascioliasis, as a neglected tropical disease, commonly affects poor people from developing countries. It has been estimated that at least 2.6 million people are infected with fascioliasis worldwide. According to the International Agency for Research on Cancer, two other liver flukes Opistorchis viverrini and Clonorchis sinensis) have been recognized as definitive causes of cancer (IARC, 2012). On the other hand even long-lasting and/ or repeated F. hepatica infections have not been associated with cancer, so far. There are any known causative associations between this parasite and cholangiocarcinoma or liver cancer.N/

Reconsidering mammal extinctions in the Pernambuco Endemism Center of the Brazilian Atlantic Forest

Reconsiderando la extinción de mamíferos en el Centro de Endemismo Pernambuco perteneciente al bosque atlántico brasileño Se ha calculado que, en los últimos 500 años, se han extinguido 21 mamíferos en el Centro de Endemismo Pernambuco. En el presente estudio, realizamos un examen crítico de los datos aportados en las publicaciones científicas históricas y recientes, y concluimos que el número real de mamíferos extintos es de siete, lo que indica que la cifra anterior de 21 especies extintas es una sobrestimación de aproximadamente 30 %. Nuestra lista difiere de las publicaciones previas en que incluye especies aún existentes (n = 5) y excluye otras que nunca habían sido registradas en el Centro de Endemismo Pernambuco (n = 8). Asimismo, señalamos que, al elaborar listas de fauna extinta a escala regional, es necesario adoptar un planteamiento más riguroso en relación con los registros históricos y recientes, dado que las identificaciones erróneas y las suposiciones falsas podrían conducir a la pérdida de credibilidad ante las partes interesadas y, en última instancia, ser negativas para la conservación de especies.In the last 500 years, there have been an estimated 21 mammal extinctions in the Pernambuco Endemism Center. We critically reviewed the published historical and recent literature records and concluded that the actual number of mammal species extinction was seven, indicating that the previous figure of 21 species lost is an overestimation of approximately 30 %. Our checklist differs from previous publications by including species that are still extant (n = 5), and removing species that have never been recorded in the Pernambuco Endemism Center (n = 8). We point out that a more rigorous approach towards historical and recent records is needed when producing lists of regionally extinct fauna, given that the implications of misidentifications and false assumptions can potentially lead to loss of credibility by stakeholders and ultimately have a negative effect on species conservation.Reconsiderando la extinción de mamíferos en el Centro de Endemismo Pernambuco perteneciente al bosque atlántico brasileño Se ha calculado que, en los últimos 500 años, se han extinguido 21 mamíferos en el Centro de Endemismo Pernambuco.

Sex differences in functional connectivity between resting state brain networks in autism spectrum disorder

Functional brain connectivity (FBC) has previously been examined in autism spectrum disorder (ASD) between-resting-state networks (RSNs) using a highly sensitive and reproducible hypothesis-free approach. However, results have been inconsistent and sex differences have only recently been taken into consideration using this approach. We estimated main effects of diagnosis and sex and a diagnosis by sex interaction on between-RSNs FBC in 83 ASD (40 females/43 males) and 85 typically developing controls (TC; 43 females/42 males). We found increased connectivity between the default mode (DM) and (a) the executive control networks in ASD (vs. TC); (b) the cerebellum networks in males (vs. females); and (c) female-specific altered connectivity involving visual, language and basal ganglia (BG) networks in ASD—in suggestive compatibility with ASD cognitive and neuroscientific theories.info:eu-repo/semantics/publishedVersio

Geo-environmental mapping using physiographic analysis: constraints on the evaluation of land instability and groundwater pollution hazards in the Metropolitan District of Campinas, Brazil

Geo-environmental terrain assessments and territorial zoning are useful tools for the formulation and implementation of environmental management instruments (including policy-making, planning, and enforcement of statutory regulations). They usually involve a set of procedures and techniques for delimitation, characterisation and classification of terrain units. However, terrain assessments and zoning exercises are often costly and time-consuming, particularly when encompassing large areas, which in many cases prevent local agencies in developing countries from properly benefiting from such assessments. In the present paper, a low-cost technique based on the analysis of texture of satellite imagery was used for delimitation of terrain units. The delimited units were further analysed in two test areas situated in Southeast Brazil to provide estimates of land instability and the vulnerability of groundwater to pollution hazards. The implementation incorporated procedures for inferring the influences and potential implications of tectonic fractures and other discontinuities on ground behaviour and local groundwater flow. Terrain attributes such as degree of fracturing, bedrock lithology and weathered materials were explored as indicators of ground properties. The paper also discusses constraints on- and limitations of- the approaches taken

Transplantation in Highly Sensitised Patients Treated with Intravenous Immunoglobulin and Rituximab

Renal transplant in highly sensitised patients is associated with increased morbidity. The aim of this retrospective study was to evaluate the clinical evolution of 30 highly sensitised deceased donor kidney transplants and the influence of different timing of B cell directed treatment and its importance in the outcome of these patients. All recipients had negative complement dependent lymphocytotoxicity cytotoxic T cell crossmatch and no identified anti human leucocyte antigen class I donor specific antibodies. T cell flow crossmatch was performed within 24h of transplantation with serum obtained pretransplant (historic, recent or baseline). Posttransplant flow crossmatch were performed prospectively starting on the 3rd posttransplantation day. The immunosuppressive regime included thymoglobulin, tacrolimus, mycofenolate mofetil and steroids. Positive flow crossmatch occurred in 20/29 patients by the 3rd posttransplantation day, and in 17/27 patients after the 3rd posttransplantation day. All patients were started on intravenous immunoglobulin before transplantation: in nine patients (group A) at 400mg/kg/day for five days; in the remaining 21 patients (group B), as a continued infusion of 2g/kg during 48h. In group A, Rituximab was added only in the presence of antibody mediated rejection; in group B, introduced on the 3rd posttransplantation day whenever a positive flow crossmatch (with serum obtained pre or posttransplant) was reported. Antibody mediated rejection was observed in 44.4% of patients in group A, and 19% of those in group B. Mean follow-up was 12.2±5.5 months. Overall allograft survival was 76.6%, 81% in group B, and 66.6% in group A. At last follow up, mean serum creatinine was 1.3±0.6 mg/dl. Renal transplantation with pretransplant positive flow crossmatch is highly associated with antibody mediated rejection, despite introduction of intravenous immunoglobulin pretransplantation. However high dose intravenous immunoglobulin for 48h plus Rituximab by the 3rd posttransplantation day reduce the incidence of antibody mediated rejection by more than 50% and allowed for allograft survival of 81% at one year, with an excellent renal function

Púrpura de Henoch-Schönlein Associada a Adenocarcinoma do Pulmão

Introduction: The Henoch-Schönlein purpura (HSP) is an immunoglobulin A (IgA)-mediated smallvessel systemic vasculitis, rare in adults. The association with solid tumours has been described, especially with lung cancer. Case Report: We present the case of a 60-year-old Caucasian male, diagnosed with lung adenocarcinoma that underwent surgical resection without (neo)adjuvant theraphy. Two months latter he was admitted for abdominal pain, purpuric rash on his lower extremities and acute kidney injury, with serum creatinine (Scr) of 2 mg/dl. Urinalysis revealed haematuria and 24h proteinuria (P24h) of 1.5 g. The serum protein electrophoresis, complement components C3 and C4, circulating immune complexes, cryoglobulins, ANCA, ANA, anti-dsDNA and the remaining immunologic study as screening for viral infections (HCV, HBV and HIV) were negative. Renal ultrasound was normal and kidney biopsy revealed mild mesangial proliferation; 2 cellular glomerular crescents and 1 fibrinoid necrosis lesion; large amounts of red blood cell casts; lymphocytic infiltration in the intertubular interstitial capillaries; moderate arteriolar hyalinosis. Immunofluorescence demonstrated mesangial and parietal deposits of IgA. The diagnosis of HSP was assumed, and the patient started prednisolone 1 mg/kg/day. Ten months after diagnosis the patient’s baseline Scr is 1.4 mg/dl with P24h of 0.18g, without haematuria. Conclusion: Although this is a rare association and the exact mechanism behind the disease is yet unknown, physicians should be aware of it. The early recognition and treatment may prevent renal disease progression
