Meta-Analysis: Relationship between Alcohol Consumption and Age on Obesity in Adults
Authors: Wulandari Ayu Novita , Hanida Amin Nur
Published: April 2022

Background: Obesity has become a serious public health problem in both developed and developing countries. Excessive alcohol consumption in adults is a global problem that needs further investigation. The adult age group has a high enough risk of being overweight and obese. The purpose of this study was to estimate the relationship between alcohol consumption and age on obesity.Subjects and Method: This research is a systematic study and meta-analysis. The articles used in this study were obtained from the Pubmed and Google Scholar databases. The articles used are articles that have been published from 2012-2022. The search for articles was carried out by considering the eligibility criteria determined using the PICO model. P= adults, I= alcohol consumption and middle age, C= no alcohol consumption and early adulthood, O= obesity. The keywords to search for articles were as follows: “Alcohol Consumption” OR “Alcohol Intake” AND “Age” AND “Obesity” OR “Body Mass Index” and “aOR”. The articles included in this study are full text articles with a cross-sectional research design. Articles were collected using the PRISMA flow chart. Articles were analyzed using the Review Manager 5.3 application.Results: There are 13 articles consisting of 2 studies from North America (Nicaragua, United States), 1 study from South America (Brazil), 1 study from Europe (Portugal), 7 studies from Africa (Ethiopia, Zimbabwe, Ghana), and 2 studies from Asia (Cambodia, Thailand) were included in this meta-analysis. 7 cross-sectional studies showed that alcohol consumption increased the risk of obesity in adults 2.05 times compared with those who did not consume alcohol (aOR= 2.05; 95% CI= 1.26 to 3.33; p= 0.004). A meta-analysis of 7 cross-sectional studies showed that middle age increased the risk of obesity 2.57 times compared with early adulthood (aOR= 2.57; 95% CI= 1.99 to 3.30; p = 0.001).Conclusion: Alcohol consumption and age are risk factors for obesity in adults.

Authors: Aprilia Sholikha Dela , Kumalasari Vilia Ayu , Utsani Wimmy Safaati , Anasulfalah Hakim
Published: April 2022

Background: Caries is an oral disease that often affects children around the world. The oral disease is related to several etiological factors with indicators of nutritional status, such as obesity and malnutrition. Studies linking overweight/obesity and caries experience in children have proved contradictory so far, the results including positive association, no association and inverse association. Therefore, this study aims to estimate the relationship between obesity and caries in children based on the results of several previous studies.Subjects and Method: This was a systematic study and meta-analysis. The search for articles was carried out by considering the eligibility criteria determined using the PICO model. The study population was children aged 6-15 years old with an intervention in the form of obesity, normoweight comparison and caries outcome. This article was collected for 3 weeks. The keywords to search for articles were as follows: “obesity” OR “overweight” AND “dental caries” AND “children”. The articles included in this study are full text articles with a cross sectional research design from 2012 to 2022. Articles were collected using the PRISMA flow chart. Articles were analyzed using the Review Manager 5.3 application.Results: A total of 9 articles contained in this study, including 3 articles from Brazil which is the continent of South America, 2 articles from Mexico which is the continent of North America, 1 article from Nigeria which is the African continent, 2 articles from China and 1 article from Arabia which is the continent of Asia. The results showed that obesity can reduce the incidence of dental caries in children by 0.82 times higher compared to children with normal weight (aOR = 0.82; 95% CI = 0.45 to 1.52; p = 0.540)Conclusion: Meta-analyses show that overweight and obese children have a lower risk of developing early childhood caries.

Authors: Yuvrista Yuliana , Marliana Wiwit
Published: April 2022

Background: Breast cancer is a type of cancer that is the main cause of death in women. Breast cancer is classified as a non-communicable disease that requires a long time for the development of cancer cells in the patient's body with various risk factors that are multifactorial. Several incidences of breast cancer are often associated with risk factors for an unhealthy lifestyle, including frequent consumption of fast food, less consumption of fruits and vegetables, lack of exercise, alcohol consumption, etc. This study aims to analyze the effect of obesity, smoking, and alcohol consumption on the risk of breast cancer in women.Subjects and Method: This study used a systematic review of meta-analysis. Data search was carried out using electronic databases consisting of: PubMed, Science Direct, Europe PMC and Google Scholar with the search keywords used were "obesity" OR "BMI" AND "smoking" OR "smoking habit" AND " alcohol” OR “alcohol consumption” OR “alcohol intake” AND “breast cancer”. Inclusion criteria were full text articles in English with case control studies collected using PRISMA guidelines, and analyzed using the Review Manager application (RevMan 5.3).Results: A meta-analysis of 9 case-control study articles originating from Europe, North America, South America, Africa, and Asia showed women with obesity had a 3.53-fold increased risk of breast cancer compared with women of normal weight (aOR= 3.53; 95%CI= 2.70 to 4.62; p<0.001). A meta-analysis of 6 case-control study articles from Europe, North America, and, Asia showed that women who smoke have a 2.62 times higher risk of breast cancer compared to women who did not smoke (aOR= 2.62; 95%CI= 1.98 to 3.46; p<0.001). A meta-analysis of 7 case-control study articles originating from the continents of Africa, North America, South America, and, Europe showed that women who consume alcohol have a 3.62 times higher risk to have breast cancer compared to women who did not consume alcohol (aOR= 3.62; 95%CI= 2.31 to 5.69; p<0.001).Conclusion: Obesity, smoking and alcohol consumption are risk factors for breast cancer.

Ovarian hyperstimulation syndrome in a bitch caused by recombinant human chorionic gonadotropin treatment of suspected luteal insufficiency – a case report
Authors: Cigánková Eliška , Vitásek Roman , Jelínková Klára
Published: April 2022

Two bitches with a history of hypoluteoidism were treated by recombinant human chorionic gonadotropin (r-hCG) in repeated doses during early dioestrus. The level of progesterone increased, but the therapy led to hyperstimulation of the ovaries which resulted in ovarian hyperstimulation syndrome (OHSS), with subsequent development of oestrogen toxicity. This is the first case documenting OHSS in a canine after administration of r-hCG. Although manifested during dioestrus in our case report, the occurrence of OHSS is associated with similar administration of r-hCG to women. The described use of r-hCG is not appropriate for luteal insufficiency treatment, but seems to have a place in assisted reproduction technology because of its surprising effects. Further research of luteotrophic factors in bitches is warranted because of these unpredictable results. Lower doses and frequency of administration need to be considered for a better outcome.

The pandemic has intensified the processes of digitalization in academic culture, which was manifested in the form of intensive development of digital platforms in education and in the request for virtual academic mobility (VAM). The advantages of academic mobility (AM) include accessibility of the scientific and educational environment of other universities since the medieval universities and since the beginning of the Bologna process, and VAM makes educational programs accessible from anywhere in the world, including asynchronous interaction. Due to the pandemic, academic exchange educational programs have switched to the VAM format, according to a survey conducted by the authors of the article. The participants of the academic communication named financial and language problems, socio-cultural differences and difficulties with IT-support among the main difficulties of the AM. These factors make the national AM in demand, which will increase the interest of graduates in the regions as a place of work. It is necessary to create a digital platform for VAM, to solve communication, organizational, managerial and technical problems. It is necessary to take into account the properties of virtual reality, the features of the educational process and the culture of academic communication between participants when designing a platform.

Published: April 2022

Los objetivos de este estudio fueron determinar y comparar el riesgo cardiovascular (RCV) en estudiantes de la carrera de preparador físico de las generaciones 2017 y 2019. Las variables medidas fueron peso corporal (PC), estatura (ES), circunferencia de cintura (CC), índice de masa corporal (IMC) e índice de cintura/estatura (ICE). Se utilizó al CC e ICE para la determinación del RCV y su posterior comparación. La metodología utilizada corresponde a un estudio cuantitativo, transversal, descriptivo: con una muestra de 324 participantes (año 2019 = 98 hombres y 62 mujeres; año 2017 = 103 hombres y 61 mujeres). Se utilizó una báscula mecánica con estadímetro marca DETECTO (para PC y ES) y una cintra métrica antropométrica SECA (para CC). Para las diferencias estadísticas se utilizó la prueba de ANOVA de dos vías y comparaciones múltiples de Sidak, se consideró el índice de D Cohen para el tamaño de efecto, con un alfa de <0.05. Los resultados de la comparación de las mujeres del año 2017 y 2019 fue significativa (p-valor <0.0001), para CC la diferencia fue mayor en 9.84% en 2019 (p-valor < 0.0001). Se determina un RCV (ICE 0.52±0.06; CC 82.34±9.86) en mujeres del año 2019. Los hombres no evidencian diferencias significativas entre el año 2017 y 2019 (p-valor >0.05), ni tampoco se clasifican como grupo de riesgo. Se concluye que las mujeres estudiantes tienen características antropométricas diferentes entre ambos años y que la generación del año 2019 presenta RCV.
Articulación de saberes matemáticos en el álgebra: Transición de lo concreto a lo abstracto
Authors: Pliego-Pastrana Patricia , Rondero-Guerrero Carlos , Tetlalmatzi-Montiel Margarita , Castillo-Gálvez Angélica María
Published: April 2022

Este trabajo tiene por objetivo analizar algunas de las posibles causas que originan las dificultades del aprendizaje de las matemáticas por parte de los estudiantes. Partimos  de considerar acerca de la complejidad de los objetos matemáticos, en la cual están involucrados, entre otros, aspectos epistemológicos, históricos y cognitivos. Tal complejidad se agudiza cuando los estudiantes ingresan al nivel medio superior, y no saben articular adecuadamente los saberes matemáticos, lo que les podría permitir realizar en forma más apropiada la transición entre el pensamiento concreto y el pensamiento abstracto. Se discute brevemente la vinculación entre Neuroeducación y Educación Matemática, lo que arroja elementos conceptuales adicionales sobre la problemática antes descrita, en donde se incluye la generalización de los saberes matemáticos. El estudio de lo anteriormente mencionado puede permitir reducir en parte los índices de reprobación y deserción escolar, relacionados con el desinterés de los estudiantes en el estudio de las matemáticas, y en general de las Ciencias Exactas.

En el contexto de la Teoría de Situaciones Didácticas propuesta por Guy Brousseau, es reconocido un juego denominado carrera al 20, en el cual dos jugadores se enfrentan y el ganador es quien llegue al número 20, luego de una secuencia de números que cada uno va diciendo, sumando uno o dos al número que dice su adversario Se puede considerar que este juego es determinista, pues en realidad es predecible lo que va a ocurrir, y existe una forma infalible de ganarlo. ¿Qué pasa cuando se modifica una de las variables? Específicamente el número de jugadores. En el presente trabajo, se hace una propuesta didáctica que consiste en agregar un tercer jugador, la intención es fomentar desde el punto de vista didáctico, la diferencia entre un sistema que se comporta como predecible o determinista, respecto de otro que resulta ser impredecible o estocástico, con la intención de promover desde la educación básica la noción de aleatoriedad.

Emergency Transport Crew: Post-Traumatic Stress Disorder Prevention Program
Authors: Dearing Heather , Kippenbrock Thomas
Published: April 2022

Background: The incidences of post-traumatic stress disorder (PTSD) among critical care nurses, emergency room nurses, and paramedics range from 20 to 33%. PTSD is associated with a lower quality of life (QOL), occupational impairments, physical health decline, and increases the risk of premature death. Research supports prevention and surveillance measures for post-traumatic stress disorder in emergency medical service providers, but the practice is not routinely done.
Methods: A multi-purpose quality improvement project focused on educating transport crew members about PTSD. Other interventions emphasized anti-stigma lessons, resiliency assistance, and coping skills training. The pilot provided surveillance efforts, employed an early organizational PTSD recognition, and immediate debriefing for at-risk personnel at three Air Evac Lifeteam bases.
Results:  After the QI interventions, most crew members’ overall post-test PCL-5 scores were lowered by 12.5%. Another measure of the QI success was the Professional Quality of Life score improvement. Specially, the compassion satisfaction average level increased by 14% and the average burnout level decreased by of 15%.
Conclusions: The QI project demonstrated the transport  crew members’ well-being can be positively influenced by a PTSD prevention and surveillance program. These interventions offer a promising reduction in the prevalence of stress and PTSD. A nationwide practice change with these project interventions could improve the mental health of helicopter emergency medical personnel.

Neuropsychiatric and behavioral disorders in patients with COVID-19
Authors: Rassokhin V. V. , Belyakov N. A. , Yakovlev A. A. , Simakina O. E.
Published: April 2022

The article discusses the epidemiological, etiopathogenetic, clinical, and diagnostic aspects of central nervous system damage in COVID-19. The SARS-CoV-2 virus can pass through physiological barriers and reach the bloodstream or lymph, spreading in the central nervous system of an infected person, infect host cells through many metabolic pathways, which determines the features of the clinical picture of neuropsychiatric and behavioral disorders in the patient, represented by a spectrum of phenotypes (syndromes), one way or another associated with the main infectious process. As a rule, this is a clinical diagnosis based on the results of a comprehensive examination of a patient with COVID-19. Direct virus-induced damage, immune dysfunction, excessive inﬂammation, thrombophilia/hypercoagulation, cytokine and metabolic imbalance, and autoimmune changes that are pathogenetic mechanisms in developing neuropsychiatric diseases in patients with COVID-19 are described. The review substantiates the need for a comprehensive examination, an interdisciplinary approach, and multicomponent therapy of patients with a new coronavirus infection. Dynamic monitoring of COVID-19 convalescents will allow us to objectively talk about the risk of developing long-term consequences of SARS-CoV-2 infection, and maintaining clinical alertness regarding the possible development of neurological symptoms in most patients with the new COVID-19 coronavirus infection will help to provide eﬀective assistance both in the acute period of the disease and during recovery, recovery and comprehensive rehabilitation: neurological, psychological, musculoskeletal.

Published: April 2022

The nature and mechanisms of damage to organs and tissues during SARS-Cov-2 infection in certain areas remain unclear over the past 2 years.

Material and methods. The study included 70 patients who underwent COVID-19 and were divided into 4 groups depending on the volume of lung damage according to the results of computed tomography. Assessment of echocardiographic parameters of longitudinal myocardial deformation (speckle-tracking) was performed on the 25–40th day of diagnosis using the GE Vivid S70 device. The histological picture of changes in the myocardium is given taking into account 30 protocols of autopsy of patients with severe and extremely severe course of the disease.

Results. Myocardial damage in the form of a violation of the longitudinal strain index (as an indirect sign of myocarditis in a number of patients, but not in those with COVID-19) was most often (in 83% of cases) recorded in the CT-3 group with a lung lesion volume of 51–75%. A nonspeciﬁc histological picture in the form of edema of myoﬁbrils, pallor of the nuclei, edema of the sarcoplasm, dystrophic changes clearly cannot be interpreted as myocarditis, and such a diagnosis has never been made, especially coronavirus. Hypertrophy of cardiomyocytes indicates the presence of chronic hypoxia, ischemia, metabolic changes (to a greater extent as a background from concomitant pathology — diabetes mellitus, hypertension, coronary artery disease). None of the examined patients who underwent an immunological blood test for the presence of “antibodies to the myocardium” were found to have such.

Conclusion. Taking into account the data obtained, we can only talk about non-speciﬁc changes in organs and tissues against the background of COVID-19, including in the myocardium. However, myocarditis was not veriﬁed in any of the cases.
Of Spirits and Virgins
Authors: Drotbohm Heike
Published: April 2022

So far religious encounters in migratory settings have been largely examined in relation to the pluralizing of religious cultures, the emerging of syncretisms as well as religious conversions. However, many migrants choose to live more than one religion at the same time and integrate themselves into several religious communities with different and sometimes opposing religious agendas. This article concentrates on the Haitian migrant community in Montreal, Canada. On the basis of the parallelisms between Vodou and Catholicism it first examines the parallels between different religious concepts and performances and second, the significance of particular Vodou spirits which act as mediators between different cultures. The article questions the idea of exclusive belongings and highlights the meaning of space as a differentiating factor in the diversification of religious meanings and messages in multicultural settings.Keywords: Vodou, Haitian diaspora, space, spirit possession, syncretism, religious parallelism

Archaeology and the Social Sciences
Authors: Kivimäki Sanna
Published: April 2022

Although aspects of the social organization of Neolithic (c. 5100–1800 calBC) hunter-fisher-gatherer societies1 in Finland have been referenced in archaeological literature since the early twentieth century (see e.g. Pälsi 1915: 108), up to the present time there has been little broad ranging analysis of the social forms of such groups. In the majority of the few case studies, Finnish-Neolithic societies have been described as generalized hunter-gatherers living in bands or, in some cases, as representatives of fairly developed tribal institutions (e.g. Halinen 2005: 104–105, 113; Seger 1982: 25, 31–32; Siiriäinen 1981: 33; for a definition of generalized hunter-gatherers, see Hayden 1997:12; the definition of band, see Service 1971b [1962]: 98, Service 1979 [1966]: 4–6; the definition of tribe, see Service 1971b [1962]: 131–132; Sahlins 1968: 15, 20–21, 24). Recently, it has been suggested (Okkonen 2003) that at least on the Middle and North Ostrobothnian coast, between about 3500–2500 calBC, the societies represented complex hunter-gatherers and were thus neither egalitarian nor stratified (Okkonen 2003: 219–226; for definitions of complex hunter-gatherers, see Arnold 1996: 78–79; Hayden 1997: 8, 11). The definition, identification and distribution of these societies have been under animated discussion in Anglo-American literature during the last few decades (see e.g. Arnold 1996; Hayden 1997; Rowley-Conwy 1998; Sassaman 2004; Zvelebil 1998).

Urban population ageing has significant implications for city centres to cater to an increasing number of older citizens. This article focuses on the city centre from the older consumers’ (aged 60+) perspective, emphasising physical and social elements in the retail and service environment. The focus-group research method was used to identify what is an age-friendly city centre that supports older consumers in running their errands. The study proved the superiority of the city centre to the older consumers. It offers an opportunity to be outdoors, enjoy the visual elements and social interactions while running errands. A wide variety of age-friendly services and the possibility of combining different activities into one visit were found to attract older consumers. The study highlights that shopping is a vital activity that promotes active and healthy ageing. Thus, older people should be respected as consumers with heterogeneous needs and preferences when creating an age-friendly city centre.
Communicating the European Ombudsman’s Mandate: An Overview of the Annual Reports
Authors: Vogiatzis Nikos
Published: April 2022

The purpose of this paper is to explore the communication strategy of the European Ombudsman (EO), focusing on the evolution of the Annual Reports (ARs) of the office from 1995 to 2010. The EO was created to bridge the gap between citizens and the EU Institutions; therefore the EO office may be seen, inter alia, as a vehicle of European communication per se. The ARs are the Ombudsman’s main instrument of political pressure and an opportunity to communicate the outcomes of the preceding year to a broad audience. It is shown that the ARs have improved significantly in terms of layout and structure, while the EO now uses a dynamic logo and website. The various communicative activities presented in the ARs are proof of the EO’s efforts to improve the office’s public image, thereby strengthening the Ombudsman’s so-called ‘moral authority’ in the context of a rather limited mandate. In terms of the legal and political messages of the ARs, the article focuses particularly on the evolution of the notion of maladministration, inter-institutional relations and the creation of a European Network of Ombudsmen. Another section addresses the similarities and differences of the two office-holders of the period under examination regarding their perception of the mandate. The article generally assesses the EO’s efforts in the communication field positively. However, from a communication-policy perspective, it is doubtful that the EO could respond to the possible preference of some citizens to contact him/her on issues which concern a national entity implementing EU law when such matters are excluded from the EO’s jurisdictional ambit.
Political Values in a European Museum

Published: April 2022

The last decades have seen the rise of a European politic of cultural identity. One of the most recent initiatives in this respect, dating from 2007, is the House of European History that is due to open its doors in 2015. In this article, we investigate the recent history of the House, in particular through an analysis of the Conceptual Basis that was meant to be its foundation. We analyse the two narrative strategies that are employed in the formation of a shared European past and cultural identity. The first is that of continuity, in which Europe’s deep roots are traced. The second is that of a shared European destiny. Finally, we investigate the criticism these plans have received.

Beyond Intergovernmentalism: The Europeanization of Restrictive Measures?
Authors: Giumelli Francesco
Published: April 2022

The functioning of the European Union (EU) has been explored extensively in recent years. The dominant prism through which to look at the EU is still one of locus: i.e. whether decisions are made in the capitals of its member states or in Brussels. This debate is contained in the dualism between intergovernmentalism and supranationalism, but drawing the boundaries between the two concepts is still undone. This article attempts to contribute to solving this problem by investigating the restrictive measures policy of the EU in order to identify three conditions under which intergovernmentalism should be used. First, when EU institutions are dependent on EU member states for information and expertise; second, when decision-making powers rest mainly in EU capitals; and three, when there are no exclusive fora for decision-making in Brussels. The study of the restrictive measures of the European Union does not meet any of these three conditions; therefore the article argues that the concept of supranational intergovernmentalism offers useful insights to understand the EU security governance of CFSP sanctions. The article is divided into four parts. The first introduces the debate on security governance and justifies the selection of this specific approach to the study of sanctions. The second part presents the restrictive measures policy of the European Union and justifies its pertinence to the field of security. The third part of the article investigates the emerging patterns in security governance by testing the three conditions on the decision-making process for EU restrictive measures. Finally, the conclusion summarises the main argument and indicates ways forward in the study of EU sanctions from a governance perspective.

El objetivo del presente trabajo fue el estudio de la morfología ovárica y la foliculogénesis de Gymnotus carapo, a fin de aportar información sobre su biología reproductiva, y que ésta sea de utilidad en el manejo de dicha especie como recurso pesquero. Se recolectaron 40 ejemplares hembras durante el periodo de febrero a diciembre del 2019 en ambientes naturales próximos a la Ciudad de Corrientes. Posteriormente a la captura fueron anestesiados con solución de lidocaína al 2% y sacrificados por sección medular. Los ovarios fueron aislados y fijados en formol al 10%; posteriormente fueron procesados para la técnica histológica convencional y coloreados con hematoxilina-eosina (H-E), tricrómica de Gomori y reacción histoquímica de PAS. Los preparados histológicos fueron analizados a través del microscopio óptico. Se pudo observar que la foliculogénesis en G. carapo es similar a la descrita para otros peces. El ovario y los ovocitos de G. carapo experimentan diferentes etapas de desarrollo: crecimiento primario, secundario, vitelogénesis y maduración durante el ciclo reproductivo, información que sienta base para estudios futuros sobre biología reproductiva. La información brindada en el presente trabajo es importante dado que aporta un estudio histológico detallado que describe la morfología ovárica y foliculogénesis en G. carapo y contribuye a la gestión y planificación de conservación de especies de importancia para el recurso pesquero.

La especie Leishmania braziliensis es responsable del mayor número de casos de leishmaniasis cutánea en el continente americano. En Argentina, las provincias del nordeste, principalmente Corrientes y Misiones, presentan la mayor prevalencia de leishmaniasis, tanto en animales como en seres humanos. Los murciélagos, por su parte, presentan una serie de características que posibilitan que puedan actuar como huéspedes potenciales de Leishmania, cumpliendo de esta manera un papel importante en la introducción y/o mantenimiento de los ciclos de transmisión de las especies de Leishmania en los centros urbanos. En Argentina, son escasos los antecedentes sobre la situación real de esta parasitosis en quirópteros, por tal motivo el presente trabajo tuvo como objetivo informar sobre el primer registro de Leishmania braziliensis en un qui- róptero insectívoro capturado en una zona urbana de la ciudad de Corrientes, identificado por técnicas de biología molecular.

El objetivo del presente estudio fue determinar las modificaciones plasmáticas de la glucosa (Gluc) y de los triglicéridos (TG) en el hígado graso no alcohólico (HGNA) inducido por DL-etionina en ratones IRMN (imagen por resonancia magnética nuclear) machos y hembras. Se distribuyeron en dos grupos de 10 animales de cada sexo: uno control y otro tratado con etionina (7,5 mg/20 g peso corporal). Después de un ayuno de 48 horas, por venopunción coccígea se obtuvo una muestra de sangre con anticoagulante y en los plasmas se cuantificaron las concentraciones de Gluc y de TG mediante kit comercial. La eutanasia se practicó bajo ligera anestesia con éter. Se disecó el hígado, se evaluó su aspecto macroscópico y se obtuvo el homogeneizado hepático, en el que se determinó la concentración de TG. Una pequeña porción de hígado fijado en formol tamponado al 10% fue utilizado para su estudio histopatológico. El análisis estadístico se realizó mediante el programa SPSS versión 17.0 para Windows. Tanto en los machos como en las hembras, la administración de DL-etionina indujo metamorfosis grasa hepática con vacuolas lipídicas en el citoplasma de los hepatocitos, así como un aumento de la concentración de TG en el tejido hepático (p<0,001). En las hembras se observó que el HG provoca un descenso de los niveles de TG plasmáticos (p<0,01), resultado que está de acuerdo con la aumentada glicemia que presentaron (p<0,05). Tales efectos se deberían a la resistencia a la insulina, anormalidad clave en el HGNA. En los machos no se modificó el nivel de TG circulantes, lo que respondería a la glicemia normal que mostraron. Como conclusión, la inducción de HG por acción de la DL-etionina afectó los parámetros plasmáticos estudiados en forma diferente en machos y hembras, quizás debido a variables adaptativas ante el HG, propias de cada sexo.

El metil mercurio (MeHg) es un contaminante ambiental tóxico y nocivo que se bioacumula y biomagnifica en la cadena trófica. La tortuga Trachemys scripta elegans (Tse), considerada centinela de contaminación ambiental debido a su longevidad, posee eritrocitos (RBCs) nucleados con afinidad del 90% por MeHg. Este estudio determinó la citotoxicidad y genotoxicidad in vitro del MeHg sobre RBCs de Tse a concentraciones de 0, 0,5, 0,7, 1, 10, 20, 50 y 100 mg/L-1 a las 24 y 96 h de exposición. Los RBCs se aislaron por centrifugación y se emplearon 1,69 x 106 RBCs por tratamiento. Se determinó el porcentaje de viabilidad, concentración letal media (CL50) y se verificaron cambios citológicos a las 24 y 96 h. El ADN fue extraído a las 96 h y se evaluó la genotoxicidad por marcadores RAPDs calculando el porcentaje de polimorfismo, índice de estabilidad genética (GST) y coeficiente de disimilaridad de Jaccard (dJSC). A las 96 h la viabilidad a 0,5, 0,7 y 1 mgL-1 de MeHg fue del 99% y 10, 20, 50 y 100 mgL-1 de MeHg fue de 94%, 20% y 0%. La CL50 determinada en 22,55 mgL-1 de MeHg. El análisis celular mostró en las diferentes concentraciones de MeHg, inclusiones citoplasmáticas, desvanecimiento o ruptura de membrana, núcleos excéntricos y lisis celular. El polimorfismo identificado fue del 85% y 50% y dJSC de 0,5 y 0,63 en 50 a 100 mgL-1 de MeHg comparado con el grupo control. La GST disminuyó hasta 42% a 100 mgL-1 de MeHg. Se concluye que el MeHg es citotóxico y genotóxico a concentraciones mayores de 10 mgL-1 en RBCs de Tse. Este estudio representa una línea base para estudios en toxicología por Hg en RBCs de Tse.

El uso de L. plantarum LP5 con potencial probiótico puede ser un enfoque alternativo para reducir la formación de biofilms de patógenos involucrados en enfermedades transmitidas por alimentos (ETA) en las industrias alimentarias. El objetivo de este estudio fue evaluar la capacidad reductora de biofilms de L. plantarum sobre el biofilms de Escherichia coli productor de toxina Shiga, Salmonella tiphymurium y Staphylococcus aureus. Fueron realizados tres ensayos: competencia, exclusión y desplazamiento. En las pruebas de competencia y exclusión, la producción de biofilms de STEC, S. tiphymurium y S. aureus fueron reducidas por efecto antibacteriano de L. plantarum LP5 (p<0,01). En la prueba de desplazamiento, si bien el biofilm producido por S. aureus, ejerció resistencia frente a L. plantarum LP5 (p<0,01), los biofilms de STEC y S. tiphymurium fueron reducidos al incorporar el cultivo de L. plantarum LP5 (p<0,01). Por lo tanto, el efecto antagónico de L. plantarum LP5 demostrado por la capacidad reductora de biofilms de bacterias patógenas involucradas en ETA lo convierte en una cepa con potencial aplicación antibacteriana en la industria alimentaria.

El objetivo de este trabajo fue evaluar histológicamente la adecuación de las dos dietas híbridas para ratones Balb/c a partir de harina integral de chia, lino y otros ingredientes naturales tipicos del NEA argentino. Ratones Balb/c fueron distribuidos en 3 grupos (n = 10) y alimentados con dieta A: control comercial, dieta B: harina integral de chía, y dieta C: harina integral de lino, durante 70 días. La adecuación nutricional de las dietas a nivel histológico se evaluó mediante tinciones H/E y PAS en muestras de estómago, duodeno, hígado y riñón. Las dietas B y C no causaron alteraciones histopatológicas en órganos del aparato digestivo, hígado y riñón.

La cría de llamas es una importante actividad de impacto socioeconómico en la región Puna de la Provincia de Jujuy, sin embargo, la misma tiene una baja tasa de procreo. Con el objetivo de estudiar potenciales causas de pérdidas reproductivas y perinatales, se controló una tropa nativa de llamas durante toda la etapa gestacional y se establecieron los índices de preñez, abortos, natimortos, teratogenia y muerte perinatal. Además, se realizaron estudios serológicos de brucelosis, leptospirosis, diarrea viral bovina, herpes virus bovino, neosporosis, sarcocystosis y toxoplasmosis en las hembras que presentaron pérdidas de gestación. El 82,8% (24/29) de las pérdidas reproductivas no pudieron asociarse a la infección con los agentes virales y bacterianos investigados. Los niveles de anticuerpos contra N. caninum, T. gondii y diferentes serovares de Leptospira sp podrían sugerir infecciones crónicas con baja relación con las pérdidas reproductivas detectadas. Astragalus garbancillo fue identificado entre la vegetación de pastoreo, y su consumo podría estar asociado a la presentación de crías con deformaciones y posiblemente abortos y mortalidad de crías débiles, siendo que los animales con mayor exposición a su consumo, tuvieron más de 4 veces mayor riesgo de padecer pérdidas peri-post-natales que los menos expuestos. Se requieren mayores estudios para establecer la asociación de estas potenciales causas con las pérdidas reproductivas, principalmente abortos y teratogenia en llamas.

La eficiencia de producción de carne y la duración de los ciclos productivos dependen principalmente del manejo nutricional de vacas y sus crías. Los terneros necesitan menos alimento para producir un kg de peso vivo (PV) con respecto a un novillito. Su potencial debe ser aprovechado para enviar a faena animales jóvenes con un adecuado nivel de engrasamiento. El objetivo del presente trabajo fue evaluar el efecto de la suplementación pre-parto y su relación con el nivel de oferta de una ración concentrada base maíz sobre el crecimiento, desempeño productivo y calidad de carne de novillitos livianos. Se utilizaron 48 terneros destetados precozmente provenientes de un rodeo con o sin suplementación y se distribuyeron en 4 tratamientos según un diseño factorial 2x2 para evaluar el efecto de la suplementación de las vacas y de una recría con o sin restricción nutricional durante la recría. Se evaluó el aumento diario de PV (ADPV), consumo, conversión, espesor de grasa dorsal (EGD) y área de ojo de bife (AOB). Los novillitos se faenaron con 380-390 kg PV a los 11-14 meses de edad y se evaluó rendimiento y calidad de la carne sobre muestras de longissimus dorsi. Los terneros recriados sin restricción consumieron el 2,5% PV y presentaron una ganancia de 1,2 kg/cab/día (cabeza), mientras que los animales con restricción en la oferta de alimento (1,8% PV) ganaron 0,9 kg/cab/d (día). La suplementación de las vacas durante el último tercio de gestación no afectó la producción ni la calidad de la carne. Sin embargo, se observó una interacción de los factores sobre el EGD, AOB y rendimiento de res. La experiencia tuvo una duración de 17 meses y se obtuvo información inédita de producción, rendimiento de res y calidad de carne de novillitos alimentados con una dieta sin fibra larga.
