Mitochondrial DNA mutations in multiple sclerosis
Authors: Kalman B , Lublin FD , Alder H
Published: January 2017

The presence of mitochondrial DNA mutations, including eight of those frequently associated with Leber's hereditary optic neuropathy (LHON), was investigated by sequencing end restriction endonuclease analysis in randomly selected patients with MS. Class I LHON mutations with primary pathogenic significance for blindness were not detected in any of the MS patients studied. A trend was observed for higher frequency of class II LHON mutations with unknown pathogenic significance in the MS patients than in the controls. Specifically, the mutation at position 4216 and its associated simultaneous mutations occurred with a higher frequency. Eleven of the 53 patients (20.8%) were positive for at least two (4216 and 4917 or 13708) or three (4216, 13 708, 15 257) simultaneous class II LHON mutations, white 7 of the 74 controls (9.5%) carried simultaneous mutations (P=0.036). Earlier studies reported the occurrence of either the 11 778 or 3460 LHON type mutations in MS patients with a positive LHON pedigree and/or with a disease course predominantly involving the optic nerves. The mutations we detected did not correlate with the severity of visual loss in either LHON or MS, rather they seemed to be present in randomly selected MS patients. We conclude that the mutations with primary pathogenic significance for blindness are not shared between LHON and randomly selected MS. However, the presence offurther mitochondrial mutations cannot be excluded in MS. The increased incidence of the simultaneous class II LHON mutations in MS patients (and LHON) vs controls may indicate that certain sets of mitochrondrial DNA mutations/variants are associated with and predispose to MS, a possibility which needs to be investigated further. Alternatively, a biological disadvantage may be associated with the coexistence of the mutations detected.
Surgery Combined with Oncological Treatments in Liver Metastases from Colorectal Cancer
Authors: Isoniemi H. , Österlund P.
Published: January 2017

The patients with colorectal liver metastases used to have a rather disappointing prognosis in the past. At present there is moderate possibility for cure with liver resection. In addition more patients are accessible for liver resection and potential cure when modern chemotherapy combined with biological agents is used. At the time of diagnosis liver metastases of 10–20% of patients are resectable. Potentially unresectable metastases can be converted to resectable in 10–15% of patients with advances in surgery together with improved oncological therapy. Resection rate increases linearly with the response rate to chemotherapy. In this century the 5-year survival rates after resection have improved remarkably being around 50% in many reports. Multidisciplinary management of metastatic colorectal cancer has increased the number of patients with potentially curative treatment and has improved patient survival.
Seeing without knowing: Limitations of the transparency ideal and its application to algorithmic accountability
Authors: Ananny Mike , Crawford Kate
Published: January 2017

Models for understanding and holding systems accountable have long rested upon ideals and logics of transparency. Being able to see a system is sometimes equated with being able to know how it works and govern it—a pattern that recurs in recent work about transparency and computational systems. But can “black boxes’ ever be opened, and if so, would that ever be sufficient? In this article, we critically interrogate the ideal of transparency, trace some of its roots in scientific and sociotechnical epistemological cultures, and present 10 limitations to its application. We specifically focus on the inadequacy of transparency for understanding and governing algorithmic systems and sketch an alternative typology of algorithmic accountability grounded in constructive engagements with the limitations of transparency ideals.

Introduction. Diffusion of sexual health evidence-based programs (EBPs) in schools is a complex and challenging process. iCHAMPSS ( CHoosing And Maintaining effective Programs for Sex education in Schools) is an innovative theory- and Web-based decision support system that may help facilitate this process. The purpose of this study was to pilot-test iCHAMPSS for usability and short-term psychosocial impact. Method. School district stakeholders from across Texas were recruited ( N = 16) and given access to iCHAMPSS for 3 weeks in fall 2014. Pre- and posttests were administered to measure usability parameters and short-term psychosocial outcomes. Data were analyzed using descriptive statistics and the Wilcoxon signed-rank test. Results. Most participants reported that iCHAMPSS was easy to use, credible, helpful, and of sufficient motivational appeal. iCHAMPSS significantly increased participants’ self-efficacy to obtain approval from their board of trustees to implement a sexual health EBP. Positive, though nonsignificant, trends included increased knowledge to locate EBPs, skills to prioritize sexual health education at the district level, and ability to choose an EBP that best meets district needs. Conclusions. iCHAMPSS is an innovative decision support system that could accelerate uptake of EBPs by facilitating diffusion and advance the field of dissemination and implementation science for the promotion of sexual health EBPs.

Published: January 2017

Cerebral mycotic aneurysms (MAs) also called infective aneurysms, are uncommon and are usually encountered in patients with infective endocarditis. These aneurysms often present with intracranial hemorrhage. MAs may resolve on treatment with antibiotics alone. However prognosis with medical management alone is unpredictable. Good prognosis with surgery has been reported for single accessible ruptured MAs. However surgery is associated with significant morbidity. Endovascular treatment of MAs along with appropriate antibiotics is emerging as an acceptable option for these patients.

We describe two cases of infective endocarditis complicated by ruptured MA treated successfully by liquid embolic glue material.
Speech Reorganization after an AVM Bleed Cured by Embolization
Authors: La Piana R. , Klein D. , Cortes MDP. , Tampieri D.
Published: January 2017

Intracerebral arteriovenous malformations (AVMs) are defined as the direct communication of arteries to abnormal veins without interposing capillaries. Although AVMs can have various clinical presentations due to their dynamic nature, the most common presenting sign is intracerebral hemorrhage. Whenever an AVM is discovered, the therapeutic choice is often not obvious and it is influenced not only by the hemodynamic features of the AVM, but also by considerations of the extent of intervention-related morbidity and mortality.

A patient with a left frontal AVM is described. He bled three years after gamma knife radiosurgery and developed aphasia. The complete obliteration of the AVM was later achieved by embolization.

Functional compensatory brain reorganization and plasticity is discussed, since our patient presented with a fast recovery from aphasia and unexpected contralateral redistribution of the speech function and with preference for his second spoken language.
Oral Administration of L. Casei CRL 431 Increases Immunity in Bronchus and Mammary Glands
Authors: de Moreno de LeBlanc A. , Galdeano C. Maldonado , Chaves S. , Perdigón G.
Published: January 2017

Lactic acid bacteria (LAB) found in numerous fermented products can interact with the gut associated lymphoid tissue increasing antibody (principally secretory IgA) production. IgA secreting cells can repopulate not only the lamina propria but also they can go to other distant sites such as bronchus, urogenital tract and mammary glands a phenomenon known as the IgA cycle. Later studies have shown that both B cells of other isotypes and T cells from Peyer's patches also exhibit gut-seeking properties. The aim of this study was to study the effect of different feeding periods of L. casei CRL 431 on the interaction with the immune cells in Peyer's patches studying the migration of not only the IgA+ cells, but also other immune cells (T lymphocytes) to other mucosal sites such as bronchus and mammary glands. BALB/c mice were fed with L. casei CRL 431 during 2, 5 or 7 days. At the end of the feeding period, the mice were killed and the small intestine, the lung and the mammary glands were removed. IgA+ cells and CD4+ and CD8+ T lymphocytes were counted in tissue slices using direct immunofluorescence. IgA+ cells increased in the intestine samples taken after 7 days of LAB feeding. In mammary gland and lung tissues, IgA+ cells increased after five days of feeding. CD4+ and CD8+ T lymphocytes were not able to migrate to sites distant from the intestine and their number did not increase in the lamina propria of the small intestine. L. casei CRL 431 was able to stimulate the IgA cycle without proliferation of T population. These results allow us to suggest that this LAB could be used as oral adjuvant to protect mucosal surfaces from intestinal and respiratory diseases, and would also be useful as an adjuvant to protect against mammary glands pathologies such as cancer.
Heart block and cardiac embolization of fractured inferior vena cava filter
Authors: Abudayyeh Islam , Takruri Yessar , Weiner Justin B
Published: January 2017

Objective:

A 66-year-old man underwent a placement of an inferior vena cava filter before a gastric surgery 9 years prior, presented to the emergency room with a complete atrioventricular block. Chest x-ray and transthoracic echocardiogram showed struts migrating to right ventricle with tricuspid regurgitation. Cardiothoracic surgery was consulted and declined an open surgical intervention due to the location of the embolized fragments and the patient’s overall condition. It was also felt that the fragments had migrated chronically and were adhered to the cardiac structures.

Methods:

The patient underwent a dual-chamber permanent pacemaker implantation. Post-implant fluoroscopy showed no displacement of the inferior vena cava filter struts due to the pacemaker leads indicating that the filter fracture had likely been a chronic process.

Results:

This case highlights a rare combination of complications related to inferior vena cava filter fractures and the importance of assessing for such fractures in chronic placements. Inferior vena cava filter placement for a duration greater than 1 month can be associated with filter fractures and strut migration which may lead to, although rare, serious or fatal complications such as complete atrioventricular conduction system disruption and valvular damage including significant tricuspid regurgitation.

Conclusions:

Assessing for inferior vena cava filter fractures in chronic filter placement is important to avoid such complications. When possible, retrieval of the filter should be considered in all patients outside the acute setting in order to avoid filter-related complications. Filter retrieval rates remain low even when a retrievable filter is in place and the patient no longer has a contraindication to anticoagulation.

Cozinhar “á Portugueza” com Lucas Rigaud. Identidade alimentar portuguesa no Cozinheiro Moderno
Authors: Gomes João Pedro
Published: January 2017

Publicado no ano de 1780, o Cozinheiro Moderno de Lucas Rigaud, cozinheiro régio, tentou estabelecer na sociedade portuguesa do final de Setecentos um novo modelo de gosto e cozinha. Certamente inspirado pela fama alcançada pelo seu companheiro de profissão, Lucas Rigaud faria uma obra à imagem e semelhança do Le Cuisinier Moderne de Vincent La Chappelle, com o claro intuito de introduzir definitivamente a nouvelle cuisine francesa em Portugal, bem como toda a variedade de receitas estrangeiras que a caracterizava. No entanto, o cozinheiro de D. José I não se desvincula por completo das tradições culinárias lusitanas e inclui 14 receitas de pratos “à Portuguesa” e cuja análise permite, em certa medida, conhecer e compreender a persistência de determinadas práticas alimentares, de origens recuadas, e que compõem o que hoje podemos denominar de identidade alimentar portuguesa.https://doi.org/10.14195/1645-2259_16_11
O exílio liberal português de 1828-1832, um fenómeno multidimensional: práticas sociais e culturais
Authors: Faria Fábio Alexandre
Published: January 2017

No contexto revolucionário europeu dos inícios do século XIX, fortemente instável, após D. Miguel regressar a Portugal do seu exílio em Viena e tomar o trono português, em 1828, milhares de liberais, fugindo da perseguição absolutista, abandonaram o país com destino ao maior exílio português de Oitocentos. Apesar de se constituir inicialmente como um fenómeno inteiramente político, o exílio liberal português de 1828-1832, assumiu-se como uma experiência bastante mais ampla, englobando uma diversidade de dimensões. Nunca perdendo a sua componente política, vincadamente presente, foi também um fenómeno de elevada importância social, cultural e intelectual,com visíveis repercussões após a  vitória liberal na guerra civil de 1832-1834. Explora-se, neste artigo, cada uma dessas dimensões e demonstra‑se que este exílio, apesar das inúmeras dificuldades que a ele estiveram associadas, contribuiu para o desenvolvimento cultural e intelectual de Portugal. Assim, dar-se-á particular atenção às práticas sociais e culturais que marcaram o quotidiano da elite liberal exilada.https://doi.org/10.14195/1645-2259_16_12
Joaquim Tomás Lobo d’Ávila, conde de Valbom: um homem da Regeneração
Authors: Pereira Hugo Silveira
Published: January 2017

A Regeneração foi marcada pela trajetória de vários homens ligados à ciência e tecnologia, que pretendiam aplicar os preceitos tecnológicos e científicos que adquiriram em escolas europeias à modernização e progresso do país. Entre essa elite encontramos o nome de Joaquim Tomás Lobo d’Ávila, conde de Valbom. Neste artigo faremos o seu esboço biográfico, dentro do âmbito do conceito de persona científica. Recorreremos para tal a um conjunto diferenciado de fontes, espalhadas por diversos arquivos e bibliotecas, que permitirão acompanhar o percurso do homem, mas sobretudo do engenheiro tecnocrata. No final esperamos demonstrar a importância do percurso individual de Lobo d’Ávila para a política de fomento encetada ao longo de grande parte do século XIX e, numa dupla perspetiva, analisar de que forma foi decisivo para a formação da persona do tecnocrata e de que modo foi o seu percurso por ela influenciado.https://doi.org/10.14195/1645-2259_16_13

Este artigo tem por objetivo apresentar a dieta alimentar dos leprosos institucionalizados na Gafaria ou Hospital de S. Lázaro de Coimbra. Partindo do regimento outorgado por D. Afonso IV a esta instituição, em 1329, descrevemos a composição da ração individual dos gafos de Coimbra e as diversas pitanças que estes doentes recebiam ao longo do ano e que enriqueciam e complementavam as suas refeições.  Simultaneamente avaliamos a terapêutica recomendada por médicos da Antiguidade e Idade Média a leprosos e a quem temia a lepra. Deste modo, estudamos o efeito que os principais alimentos podiam ter no tratamento da doença ou, pelo menos, no reforço de corpos fragilizados por ela, ajudando-os a enfrentá-la e adiando o inevitável desfecho.https://doi.org/10.14195/1645-2259_16_3
A lógica do poder no Livro de vertuosa benfeytoria
Authors: Prata Jorge Manuel De Matos Pina Martins
Published: January 2017

Organizado em torno de uma estrutura especular, a Vertuosa Benfeytoria apresenta‑nos uma teoria do poder que se ancora na tradição dos grandes textos chave da filosofia política medieval, concebendo o poder como instituído originariamente por Deus, e desdobrando uma diferenciação  entre poder e uso do poder, entre Poder-Instituição e Governante. Poder  em abstrato que se desdobra em três tipos diferentes de concretização efetiva: Auctoritas, Dominium e Poder Político, sendo o Poder Político o  correlato da sociedade humana organizada, cuja encarnação numa forma determinada de regime – a monarquia – se procura naturalizar, de modo a apresentá-la como tipo único e necessário do governo dos homens, governo esse orientado para o bem comum da coletividade, e no seio do qual o governante se apresenta menos como detentor de direitos do que como obrigado a deveres. Oficium que impõe preceitos cuja inobservância  pode conduzir à deposição do detentor do uso do poder. Prevalência do bem comum que não impede que a sociedade se organize em torno de uma desigualdade fundamental e naturalizada. No fim, uma utopia: o retorno à inocência das origens, com a abolição do poder político, e a emergência de um poder sem poder, fundado no amor e na dádiva.https://doi.org/10.14195/1645-2259_16_4

Published: January 2017

Background An increase in protein loss through the intestinallumen is commonly found in children with intestinal inflammation. Measurement of fecal alpha-1 antitrypsin (FAA T) concentration has been used to detect the loss of protein through the digestive system. FAAT concentration increases in diarrhea patients due to Rotavirus, Adenovirus, Shigella, Enterotoxigenic E. coli (ETEC), and Salmonella infection.Objective To determine the relationship between types ofpathogen, acute diarrhea, and alpha-1 antitrypsin concentrationin children with acute diarrhea caused by Rotavirus andenteropathogenic infection.Methods Descriptive statistics and proportion difference betweenthe two non-related groups were used to assess the proportion ofprotein-losing enteropathy (PLE) in children with acute diarrheaand was analyzed using chi square test.Results In this study, PLE group comprised 25% (24/95) subjectswithout unknown cause of diarrhea, 50% (4 7 /95) had one typeof pathogen, and in 23% (22/95) subjects had 2 or more types of pathogens. The most common pathogen found in PLE group was Rotavirus, found in67 (53%) subjects and E. coli in 41 (33%) subjects. In non-PLE group, we also found similar pathogen pattern. The mean alpha-1 antitrypsin (AAT) concentration in acute diarrhea group due to Rotavirus infection was significantly higher (P= 0.003) compared to acute diarrhea groups caused by non-Rotavirus infection. The mean AAT concentration in acute diarrhea group due to E. coli infection did not differ significantly (P= 0.735) compared to acute diarrhea group caused by non-E. coli infection.Conclusion Rotavirus was a more significant cause of PLEcompared to E.coli.

Conocimientos sobre las bebidas energéticas: una experiencia educativa con estudiantes de secundaria básica de Barcelona, España
Authors: Sánchez-Socarrás Violeida , Blanco Meritxell , Bosch Carme , Vaqué Cristina
Published: January 2017

Introducción: La popularidad de que gozan las bebidas energéticas entre los adolescentes y jóvenes, ha aumentado en los últimos años. El aumento del consumo entre los estudiantes motivó el diseño de un taller educativo en un grupo de adolescentes, con el objetivo de aumentar el nivel de conocimientos sobre las características de estos refrescos y sobre sus posibles efectos para la salud; así como de evaluar el impacto del taller respecto a estos conocimientos.Material y Métodos: Se realizó un estudio de intervención con evaluación pre- y post- intervención en un instituto de Manresa, Barcelona. Se aplicó un cuestionario de conocimientos sobre las Bebidas Energéticas antes y después de realizar un taller educativo, en el que se emplearon técnicas de enseñanza afines a los Estilos de Aprendizaje preferentes de los participantes.Resultados: Las técnicas de enseñanza, correspondieron a las estrategias preferentes para los estilos auditivo (32,3%) y quinestésico (23,7%) predominantes en el colectivo. En la evaluación previa: el 76,3% de los adolescentes definen las Bebidas Energéticas como isotónicas para deportistas, la mayoría reconocen su elevado contenido en cafeína (95%), el 61,3% considera que aportan energía para el deporte, el 76,3% que pueden provocar nerviosismo y el 28% creen que no han de ser consumidas por adolescentes. En la evaluación posintervención aumentó el número de estudiantes que respondió correctamente en todas las preguntas del cuestionario.Conclusiones: Un gran número de adolescentes tiene poco o nulo conocimiento sobre las características de las bebidas energéticas y las consecuencias de su consumo para la salud, que mejora significativamente tras la realización de un taller a través de técnicas de enseñanza participativas y cooperativas afines a las estrategias de aprendizaje preferente de los participantes.
Procesos de recepción y efectos socio-cognitivos de películas sobre inmigración. El papel moderador del prejuicio hacia inmigrantes
Authors: Igartua Juan José , Frutos Francisco Javier
Published: January 2017

Se presentan los resultados de una investigación sobre el impacto de películas sobre inmigración en las actitudes hacia dicho colectivo. Se realizó un estudio cuasi-experimental con 142 estudiantes de Bachillerato, estableciéndose dos condiciones: ver una película que enfatizaba la discriminación y suscitaba reacciones de empatía hacia los inmigrantes (Poniente) o ver una película que enfatizaba el contacto intergrupal positivo (El Próximo Oriente). Un mes antes del visionado de las películas se cumplimentó la escala de racismo moderno. Tras el visionado de las películas se midieron la identificación con los personajes del endogrupo y del exogrupo, la actitud hacia la inmigración y otros procesos de recepción relevantes. El visionado de la película diseñada para estimular empatía hacia los inmigrantes provocó mayor identificación con los personajes del exogrupo, lo que a su vez indujo actitudes más positivas hacia la inmigración, pero únicamente cuando el prejuicio previo era bajo o moderado.
Inmigrantes emprendedores durante la crisis económica. Estudio de casos en la ciudad de Madrid
Authors: Cebrián de Miguel Juan Antonio , Jiménez Blasco Beatriz Cristina , Resino García Rosa María
Published: January 2017

Los inmigrantes emprendedores han tenido que adaptar sus negocios o, incluso, abandonarlos, debido al impacto de la crisis económica que ha afectado de forma muy especial al consumo y, por tanto, a la actividad comercial en general. Para apreciar los cambios habidos en esta etapa se han seleccionado seis ejes urbanos de la ciudad de Madrid, con presencia significativa de negocios de titularidad extranjera, y que los autores habían estudiado en el año 2009. Y se han vuelto a visitar y analizar en 2015. Actualmente, el llamado empresariado étnico, para mantener sus negocios, tiende a captar una clientela más amplia, abandonando una excesiva especialización y mejorando la presencia de los establecimientos comerciales y de los productos y servicios que ofrece.
El derecho de extranjería y su incidencia sobre el transnacionalismo migrante
Authors: Barbero Iker , Blanco Cristina
Published: January 2017

El transnacionalismo, en tanto que perspectiva de estudio de nuevas formas de migrar, ha evidenciado que muchas personas migrantes mantienen vínculos estrechos y sostenidos en el tiempo con sus comunidades de origen. Muchos estudios se centran en la identificación y recuento de actividades transnacionales de los migrantes para poder diferenciar lo que es una migración transnacional de lo que no lo es. Nosotros partimos de la hipótesis de que la actividad transnacional manifestada no coincide con la potencial en la medida en que ésta cambiará cuando cambien los factores que influyen en ella. Entre estos factores se encuentra el Derecho y las normas de extranjería. El artículo tiene como objetivo fundamentar la necesidad de abrir un espacio de reflexión y una línea sólida de investigación que se centre en la incidencia del Derecho en la generación u obstaculización del transnacionalismo migrante, línea de investigación escasamente tratada. Para ello nos basamos en la información que ofrece un amplio estudio sobre población andina en el País Vasco, concretamente una encuesta realizada en 2012 a 604 personas inmigrantes y 35 entrevistas en profundidad realizadas en 2011. Sin ser un estudio jurídicamente específico, sí nos ofrece indicios sólidos para fundamentar futuras investigaciones. Tales indicios muestran la existencia de actividades transnacionales que los inmigrantes realizan por necesidad, como consecuencia de situaciones normativas específicas (transnacionalismo inducido), mientras que en otros casos las personas migrantes desearían establecer relaciones con sus países de origen, pero lo impiden las condiciones jurídicas que les rodean (transnacionalismo latente).
Inmigrantes, estrategias familiares y arraigo: las lecciones de la crisis en las áreas rurales
Authors: Sampedro Gallego Rosario , Camarero Rioja Luis
Published: January 2017

El asentamiento de población de origen extranjero en las áreas rurales españolas en las últimas décadas ha sido considerado como una oportunidad para la revitalización demográfica y social del mundo rural. La crisis económica que comienza en 2008 abre interrogantes sobre los factores que pueden favorecer o dificultar el arraigo rural. En este artículo analizamos la evolución de la población inmigrante en Castilla y León entre 2007 y 2014, utilizando datos de los Padrones Municipales y del Censo de Población de 2011. Relacionamos esta evolución con los modelos familiares de migración y de inserción laboral de cinco grupos distintos de inmigrantes según su origen nacional. Los datos sugieren que determinadas estrategias familiares —vinculadas a las familias transnacionales o al matrimonio con españoles—y determinados modelos de inserción laboral —con una clara especialización sectorial por género— se relacionan con la permanencia de los inmigrantes en las áreas rurales.

A experimentação é sem dúvida um dos grandes pilares da Física e uma importante forma de fomentar o processo de ensino-aprendizagem contextualizado e dinâmico. Entretanto, a experimentação por si só, sem uma reflexão profunda do fenômeno, sem dar a oportunidade do discente questioná-lo e construir a visão do mundo pode ser uma pseudo-aprendizagem. De maneira geral pontuaremos sobre as motivações, as condições e possíveis contribuições da experimentação no Ensino de Física.

An unusual, exotic, ammonite fauna including Romaniceras mexicanum Jones, 1938, Prionocyclus hyatti (Stanton, 1894) and Coilopoceras cf. springeri Hyatt, 1903 is recorded from the late Middle Turonian of Vaucluse and Gard, southern France. It is the first record of this ammonite association outside the Gulf Coast region and the Western Interior of the United States of North America. Up to present, these species were considered as endemic to the Western Interior sea-way. The migration of numerous ammonites from North America to western Europe during the late Middle Turonian suggests it is linked to a transgressive event or to a short sea-level high.

The aim of this work was to investigate the possibility of using UV irradiation for degradation of deoxynivalenol (DON) in naturally contaminated maize samples. The study was carried out by varying the distance of the contaminated maize from the UVA (368 nm) and UVC (254 nm) light source and duration of exposure of contaminated maize to UV irradiation. Two control samples of maize were used for the irradiation procedure, at DON levels of 1.902 mg/kg and 5.334 mg/kg. The samples were exposed to both UVA and UVC light at two different distances from UV lamp (15 and 30 cm) during three exposure intervals (30, 60 and 120 minutes). After irradiation DON content was determinated so the reduction levels could be quantified. Generally, the results showed reduced DON content in treated samples, but they were not consistent. The most probable reason for this was a very uneven DON distribution in naturally contaminated samples. For this reason, further research must be performed and should include irradiation of artificially inoculated samples with consistent DON distribution, the amount of irradiated sample needs to be enlarged and the higher number of replicates should be analyzed. As an additional improvement, an increase in frequency of sample mixing during the irradiation procedure needs to be done.

Components of yield and seed quality are traits of primary importance in bread wheat breeding programs. Yield components are obviously a major determinant of farmer’s income, whereas seed quality is very important for breeding quality. In this paper, the thousand grain weight (TGW) was chosen as indicative of yield features and the shelling percentage (RND) as indicative of seed quality (although RND is not directly connected to the technological/seed quality, but rather indirectly and it greatly contributes to the wider picture of seed quality). The objectives of the present research were two-fold: to determine the influence of genotype, the environment and their interaction on the thousand grain weight and shelling percentage and to evaluate the stability via the AMMI model. The grain samples were obtained from ten winter wheat cultivars grown in 2009/10, 2010/11, 2011/12 at three locations in Serbia: Novi Sad, Sremska Mitrovica and Pančevo. The ten winter wheat cultivars used in this study were: Evropa 90, NSR-5, Pobeda, Renesansa, Ljiljana, Cipovka, Dragana, Simonida, NS 40 S and Zvezdana. The thousand grain weight and shelling percentage were investigated and statistically analyzed via the AMMI model, which showed significant differences between genotypes at various locations and ASV rankings. The most favorable cultivar in the experiment was Dragana in terms of all investigated traits.

The aim of this study is to investigate the influence of hemolysis degrees on the values of hematological and biochemical parameters in the blood samples of cows in early lactation. The study included a total of 45 blood samples of cows in early lactation. Out of the total number of samples analyzed, 15 indicated no signs of hemolysis, whereas 15 indicated moderate hemolysis and 15 severe hemolysis. The influence of hemolysis was examined by determining the bias (%) and by means of the Wilcoxon signed-rank test. The results showed that the hemolyzed samples had decreased values of the HCT, RBC, MCV, and increased values of the MCH, MCHC, and PLT. The total number of LEU showed a declining trend with increasing degrees of hemolysis. The changes in the HGB values were not detected despite the visual identification. The hemolysis degrees showed a significant influence on the values of biochemical parameters. The variations in biochemical parameters were less significant in the samples with moderate hemolysis compared to the samples with severe hemolysis. The most hemolysis-sensitive biochemical parameters were the AST, TBIL, TGC, and NEFA as great variations of their values were found even in moderate hemolysis. A slight deviation was noted in the BHB and total protein values. With respect to all the parameters examined, the Wilcoxon test showed significant differences in the samples with moderate and severe hemolysis in comparison with the control group. In conclusion, hemolysis significantly influenced the values of hematological and biochemical parameters in the blood samples analyzed.

Authors: Curić Jasmina , Kačar Bahrija , Ikić Selma
Published: January 2017

Sustainability of agricultural production in the world is in serious crisis. Interdependence of agricultural production and the environment is multiple and causality works both ways. On one hand, there are environmental changes which hamper food production, and on the other, the agricultural production, as it is, is severely damaging the environment. The very systems of agricultural production jeopardize future production. The goal of this paper is to explore causes of limitations of sustainable agricultural development in the world, where the authors emphasize the following: gas emissions with greenhouse effect, a disturbed cycle of nitrogen circulation and destruction of biodiversity.

We explored the factors of interdependence of environment and agricultural production and possibilities of sustainable development with a methodological frame work of research, analyzing, comparing and synthesizing domestic and international literature. The authors propose a holistic approach to sustainable development, carefully suited to the regional and local circumstances.
Disparities in Mortality Rates of Working-Age Population in Eastern, Central and Western Europe – A Comparative Quantitative Analysis
Authors: Lackó Mária
Published: January 2017

Even two decades after the start of transition, mortality rates in Central and Eastern Europe are much higher than in Western Europe. This study presents and quantifies the impact on mortality of factors beyond the usual explanations. These factors are the advantageous and disadvantageous health effects of the geographical location of individual countries, as well as the economic structure, price structure and political priorities of the pre-transition systems in Central and Eastern Europe associated with anomic, self-destructive lifestyles. For adult males, mortality results show significant impact from level of development, health expenditure, latitude of countries, spirit consumption, education and air pollution. The impact of development, health expenditure, latitude, air pollution appear the same for both gender’s mortality.

Published: January 2017

The recent advances and potential applications of nanoparticles and nanofibres for energy, water, food, biotechnology, the environment, and medicine have immensely conversed. The present review describes a ‘green’ method for the synthesis and stabilization of nanoparticles and ‘green electrospinning’ both using tree gums (arabic, tragacanth, karaya and kondagogu). Furthermore, this review focuses on the impending applications of both gum stabilized nanoparticles and functionalized membranes in remediation of toxic metals, radioactive effluents, and the adsorptive removal of nanoparticulates from aqueous environments as well as from industrial effluents. Besides, the antibacterial properties of gum derivatives, gum stabilized nanoparticles, and functionalized electrospun nanofibrous membranes will also be highlighted. The functionalities of nanofibrous membranes that can be enhanced by various plasma treatments (oxygen and methane, respectively) will also be emphasized.

Published: January 2017

The cyanobacterium Nostoc linckia was used to study the biotechnology of selenium nanoparticles synthesis for the first time. The experimental conditions of the nanoparticle production by the studied cyanobacteria in aqueous cobalt selenite solutions were examined. Neutron activation analysis allowed characterization of the dynamics of accumulation of the total selenium quantity by Nostoc linckia. Scanning Electron Microscope images demonstrated extracellular formation of amorphous nanoparticles. Released selenium nanoparticles ranged in size from 10 to 80 nm. The changes of essential parameters of biomass (proteins, lipids, carbohydrates, and phycobilin) content during the nanoparticle formation were assessed. During the first 24 h of nanoparticle synthesis, a slight decline of proteins, lipids and carbohydrates content in the biomass was observed. The most extensive was the process of phycobilin degradation. Furthermore, all biochemical component content as well as an antioxidant activity of the biomass extracts significantly decreased. The obtained substance of Nostoc biomass with selenium nanoparticles may be used for medical, pharmaceutical and technological purposes.

Published: January 2017

In the paper some results on measurement of insolation and „real” cell’s temperature carried out with use of standard silicon solar cells are presented. Two identical cells are applied in such a sensor. Short circuit current of one cell is a direct indication of insolation value and open circuit voltage of the other cell is indirect indication of actual sensor’s temperature but in this case more complex formula must be used for temperature calculation.

Published: January 2017

Snow samples were collected during winter 2011/2012 in three posts in the Western Sudety Mountains (Poland) in 3 consecutive phases of snow cover development, i.e. stabilisation (Feb 1st), growth (Mar 15th) and its ablation (Mar 27th). To maintain a fixed number of samples, each snow profile has been divided into six layers, but hydrochemical indications were made for each 10 cm section of core. The complete data set was subjected in the first run of chemometric data interpretation to Cluster Analysis as well as Principal Components Analysis. Further, Self-Organizing Maps, type of neutral network described by Kohonen were used for visualization and interpretation of large high-dimensional data sets. For each site the hierarchical Ward’s method of linkage, squared Euclidean distance as similarity measure, standardized raw data, cluster significance test according to Sneath’s criterion clustering of the chemical variables was done. Afterwards this grouping of the chemical variables was confirmed by the results from Principal Components Analysis. The major conclusion is that the whole system of three sampling sites four patterns of variable groupings are observed: the first one is related to the mineral salt impact; the second one - with the impact of secondary emissions and organic pollutants; next one - with dissolved matter effect and the last one - with oxidative influence, again with relation to anthropogenic activities like smog, coal burning, traffic etc. It might be also concluded that specificity of the samples is determined by the factors responsible for the data set structure and not by particular individual or time factors.
