Transmission routes of African swine fever virus to domestic pigs: current knowledge and future research directions
African swine fever (ASF) is a major threat to the pig industry in Europe. Since 2007, ASF outbreaks have been ongoing in the Caucasus, Eastern Europe and the Baltic countries, causing severe economic losses for many pig farmers and pork producers. In addition, the number of ASF cases in wild boar populations has dramatically increased over the past few years. Evidence supports direct contact with infectious domestic pigs and wild boars, and consumption of contaminated feed, as the main transmission routes of ASF virus (ASFV) to domestic pigs. However, significant knowledge gaps highlight the urgent need for research to investigate the dynamics of indirect transmission via the environment, the minimal infective doses for contaminated feed ingestion, the probability of effective contacts between infectious wild boars and domestic pigs, the potential for recovered animals to become carriers and a reservoir for transmission, the potential virus persistence within wild boar populations and the influence of human behaviour for the spread of ASFV. This will provide an improved scientific basis to optimise current interventions and develop new tools and strategies to reduce the risk of ASFV transmission to domestic pigs.ISSN:0042-490

Effect of Carvacrol on Salmonella Saintpaul Biofilms on Stainless Steel Surface
Purpose: To evaluate the effect of carvacrol against Salmonella Saintpaul biofilms on stainless steel surface.Methods: The effects of carvacrol on planktonic cells were evaluated by determining the minimum inhibitory concentration and minimal bactericidal concentration. The action of carvacrol on Salmonella Saintpaul biofilms on stainless steel surface was evaluated on established biofilm and on biofilm formation by counting the number of bacterial cells that adhered to the surface using scanning electron microscopy.Results: The antimicrobial activity of carvacrol in planktonic cells of Salmonella Saintpaul was observed. The highest inhibitory effect of carvacrol was observed on biofilm formation at different subinhibitory concentrations.Conclusion: Carvacrol reduced the number of bacterial cells that adhered to stainless steel surface, making it a potential compound for Salmonella Saintpaul control.Keywords: Salmonella spp, Biofilm, Planktonic cells, Carvacrol, Stainless stee
Ethnobiology of snappers (Lutjanidae): target species and suggestions for management
In this study, we sought to investigate the biology (diet and reproduction) and ethnobiology (fishers knowledge and fishing spots used to catch snappers) of five species of snappers (Lutjanidae), including Lutjanus analis, Lutjanus synagris, Lutjanus vivanus, Ocyurus chrysurus, and Romboplites saliens at five sites along the northeast (Riacho Doce, Maceió in Alagoas State, and Porto do Sauípe, Entre Rios at Bahia State) and the southeast (SE) Brazilian coast (Paraty and Rio de Janeiro cities at Rio de Janeiro State, and Bertioga, at São Paulo State.)
Dementia in a patient with Thymoma and hypogammaglobulinaemia (Good's syndrome)
Good's syndrome is extremely rare and refers to an acquired B and T cell immunodeficiency in thymoma patients. The authors of this article present a case report of a 75-year-old, caucasian male patient previously subjected to examinations for secondary dementia and recurrent infections, which revealed paraneoplastic syndrome arose from thymoma. He underwent thymectomy, while his immunodeficiency syndrome sustained with frequent opportunistic infections, constantly requiring intravenous immunoglobulin treatment

Intact triacylglycerol profiles of fats and meats via thermal imprinting easy ambient sonic-spray ionization mass spectrometry
Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Thermal imprinting (TI) on a paper surface, using minimal solvent amounts, followed by direct analysis of the triacylglycerols (TAG) content via easy ambient sonic-spray ionization mass spectrometry (EASI-MS) is shown to provide a fast protocol to analyze TAG in meats and fats. The technique is simple, fast and eco-friendly requiring no hydrolysis, derivatization or chromatographic separation. The entire TI-EASI-MS protocol is performed in a few minutes and with minimal sample handling and solvent consumption. The TAG profiles obtained via TI-EASI-MS are shown to be quite similar to those obtained using GC and MALDI-MS analyses, and the imprinting and mailing of the imprinted paper in a sealed plastic bag is proposed for remote TI-EASI-MS analysis of meat and fat samples.41135513557Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Financing Agency of Studies and Projects (FINEP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq
Novedades en la farmacoterapia del dolor óseo de origen maligno y no maligno.
Introducción: El dolor óseo es un síntoma debilitante que puede aparecer en un gran número de trastornos tanto malignos como no malignos y existen indicios que la prevalencia va a aumentar en las próximas
décadas.
El objetivo de esta revisión es recopilar y resumir la evidencia disponible sobre el tratamiento farmacológico actual del dolor óseo tanto en patologías de origen oncohematológico como de origen no maligno.
Método: Para responder al objetivo de nuestro trabajo se realizó una búsqueda exhaustiva de la literatura publicada en las principales bases de datos hasta el 31 de abril de 2016.
Resultados: Los fármacos antirresortivos, como los bifosfonatos, y aquellos que estimulan la formación del hueso, como la teriparatida, junto a analgésicos, como los AINEs y lo opioides, son actualmente la base farmacológica
para tratar el dolor óseo (dependiendo de qué patología se trate).
Existen nuevas hipótesis sobre diferentes mecanismos que pueden estar relacionados con la génesis del dolor, con el consecuente desarrollo de nuevas moléculas con distintos y novedosos mecanismos de acción.
Conclusiones: Es necesario que se desarrollen más estudios que aclaren aspectos inciertos relacionados con el tratamiento del dolor óseo y permita el desarrollo de nuevos fármacos. Los farmacéuticos deben de estar
actualizados sobre el arsenal terapéutico disponible en la actualidad para el tratamiento del dolor óseo como el primer paso para llevar a cabo una atención farmacéutica de calidad
