Introdução: Para que a eliminação da hanseníase no município seja mantida de maneira eficaz, são necessários estudos que explorem melhor a endemia ao longo dos anos adotando outros recursos que não só indicadores epidemiológicos preconizados pelo Ministério da Saúde. Objetivo: Analisar a endemia da hanseníase por meio da classificação operacional, baciloscopia, idade e deficiência física no diagnóstico. Material e Métodos:Coletamos dados clínicos e epidemiológicos no período de 02/01/1998 a 31/07/2015.Consideramos baciloscopia positiva e negativa; paucibacilares e multibacilares e pacientes Graus 1 e 2 com deficiências físicas. Resultados:Um total de 470 casos foi incluído. A média de idade foi de 49,1 (DP 15,67) anos, predomínio dos multibacilares (64,7%), com deficiência (45,3%) e baciloscopia positiva (30%). Na análise univariada, a baciloscopia positiva foi significante para homens, multibacilares e com deficiência (valor p<0,05). Na análise multivariada, ter baciloscopia positiva aumenta para multibacilares (OR=39,13) e para homens (OR=2,27). A linha de tendência dos indicadores de prevalência, incidência e taxa de casos novos com Grau 2, mostram-se em declínio. Conclusão: Os resultados indicam diagnóstico tardio e geram a hipótese de endemia alta, embora sua análise por meio dos indicadores epidemiológicos mostra-se em declínio.
A new design of an electrospinning apparatus for tissue engineering applications
Authors: R. Dias Juliana , Santos Cyril dos , Horta João , Granja Pedro Lopes , Bártolo Paulo Jorge
Published: July 2017

The electrospinning technique is being widely explored in the biomedical field due to its simplicity to produce meshes and its capacity to mimic the micro-nanostructure of the natural extracellular matrix. For skin tissue engineering applications, wound dressings made from electrospun nanofibers present several advantages compared to conventional dressings, such as the promotion of the hemostasis phase, wound exudate absorption, semi-permeability, easy conformability to the wound, functional ability and no scar induction. Despite being a relatively simple technique, electrospinning is strongly influenced by polymer solution characteristics, processing parameters and environmental conditions, which strongly determine the production of fibers and their morphology. However, most electrospinning systems are wrongly designed, presenting a large number of conductive components that compromises the stability of the spinning process. This paper presents a new design of an electrospinning system solving the abovementioned limitations. The system was assessed through the production of polycaprolactone (PCL) and gelatin nanofibers. Different solvents and processing parameters were considered. Results show that the proposed electrospinning system is suitable to produce reproducible and homogeneous electrospun fibers for tissue engineering applications.
Modified Alvarado scoring system as a diagnostic tool for acute appendicitis at a tertiary care teaching hospital, Central India: a cross sectional study
Authors: Kothari Dilip , Kothari Archana , Kalantri Abhishek , Bhambani Pawan
Published: July 2017

Background: Acute Appendicitis forms an important emergency in the day-to-day surgical practice. It affects human beings irrespective of age, nationality and religion. Early diagnosis and prompt operative intervention is the key for successful management of acute appendicitis. However, the picture of acute appendicitis may not be classical, and in such situations, a policy of early intervention to avoid perforation may lead to high negative appendicectomy rates.Methods: A total of 80 patients were enrolled in the present cross sectional study. Their ages ranged from eleven to 72 years (mean 32.89 ± 15.87). A proforma containing general information about the patient plus eight variables based on the modified Alvarado scoring system was filled.Results: Histological examination confirmed appendicitis in 54 patients (67.5%). The remaining 26 patients were found to have normal appendix giving a negative appendicectomy rate of 32.5% being 36.8% and 28.3% for males and females respectively.Conclusions: This scoring system is easy, simple and cheap complementary aid for supporting the diagnosis of acute appendicitis. MASS can be used effectively in Indian setup to reduce the incidence of negative appendectomies. The patients are not unduly exposed to risks of delay in intervention or significant increase in number of false negative cases.
Comparison of endoscopic underlay and microscopic underlay tympanoplasty: a prospective research at a tertiary care centre in Gujarat
Authors: Sinha Mohit , Hirani Narendra , Khilnani Ajeet Kumar
Published: July 2017

Background: Tympanoplasty is an ever evolving surgery with myriad of approaches and tools. Use of endoscope is relatively new and there are few studies evaluating the use of endoscope via microscope because of a big learning curve in using one hand endoscopic technique despite it being minimally invasive.

Methods: This is a prospective study conducted from June 2016 to May 2017 with a sample size of 44 patients. The study included patients of Chronic Otitis Media (COM) of mucosal inactive type without any co-morbidities in which only Type-1 tympanoplasty was done. The patients were divided into endoscopic or microscopic group using simple random sampling and after taking written and informed consent. The patient’s details regarding audiometric, oto-endoscopic and nasal endoscopic evaluation were recorded. Intra operative findings, duration of surgery and post-operative pain scoring were recorded. The patients were followed up for 3 months and subjected to post-operative audiometry and patient satisfaction questionnaire. The groups were evaluated for graft take up and closure of air bone gap, post-operative complications and patient satisfaction. The results were analysed using descriptive statistics (mean and percentage) and CHISQ test.

Results: Graft was taken up in 21 patients (95%) in microscopic as opposed to 20 in endoscopic group (90%). Mean VAS scoring for pain was 2.5 in microscopic group on first post-operative day and 1.5 for the endoscopic group. The mean improvement in air bone gap post-surgery was 23.68 dB (SD=4.94) for microscopic group and 16.13 dB (SD=6.49) for endoscopic group.

Conclusions: Endoscopic tympanoplasty as a technique has a long learning curve. The results indicate that endoscopic technique is as efficacious as and less invasive than microscope surgery for doing tympanoplasty. 
Granuloma due to sweet almond oil injection: Difficulties of diagnosis and treatment
Authors: Crocco Elisete Isabel , Dalapicola Monique , Diniz Renata , Alves Renata , Lazzarini Rosana , Lellis Rute
Published: July 2017

Foreign body granuloma reaction is a tissue response to some extraneous materials which incite a characteristic pattern of granulomatous reaction. Several cases of foreign body granulomas on the face have been reported, especially after the injection of dermal fillers. Oleoma or paraffinoma is defined as a foreign body granuloma resulting from the injection of oily substances into the skin or subcutaneous tissue. We report a case of an adult woman who had developed foreign body granulomas due to a self-injection of sweet almond oil into the glabella and periorbital area. The diagnosis was based on a thorough interrogation, clinical features and histopathological findings. Treatment of foreign body granuloma is challenging. At first, oral prednisone was initiated with the improvement of the inflammatory signs and reduction of the lesions’ dimension, but recurrence of the lesions occurred when the dose was decreased. After research of literature, a low-dose minocycline regime was prescribed for its beneficial effects in granulomatous diseases, with encouraging results.

Authors: Sam Yang Shiyao , May Liau MeiQi , Khee Heng Jun , Matthias Toh Han Sim , Derrick Aw Chen Wee , Sue-Ann Ho
Published: July 2017

Glycolic acid peels have been shown in many studies to improve the appearance of photoaged skin. Vitamin C is known to be a potent natural antioxidant and plays an important role in the collagen biosynthetic pathway. In this study, we report our clinical experience with 70% glycolic acid peel added with vitamin C. We found that all parameters of photoaging, in particular the composite wrinkling score, discolouration score and the global photoaged score, showed statistically significant improvement. Patient satisfaction also revealed improvement in keeping with the physician assessment. It is also associated with an excellent safety profile. In conclusion, a combination of 70% glycolic acid with vitamin C chemical peel is a well-tolerated effective treatment of photoaging in Asian skin.
Xanthan and Poly(vinyl alcohol) - Based Composite Films, as Supports for Chloramphenicol Immobilization
Authors: Corneliu Alupei Iulian , Marcel Popa , Mihaela Hamcerencu , Alexandru Savin , Marc Jean Abadie
Published: July 2017

The paper discusses a method for the realization of some polymer - drug systems in which the macromolecular support is represented by a three-dimensional network based on xanthan and poly(vinyl alcohol). Knowing that the drug (chloramphenicol) was to be inserted through a diffusion process, the support – selected according to an experimental program – had the highest degree of swelling. Several variants of chloramphenicol inclusion into the synthesized support are analyzed by studying the process kinetics. The study of chloramphenicol release from the inclusion products, in the form of films, indicated the installation of a “zero order” kinetics. The tests devoted to the system’s antimicrobial activity evidenced their biological action.
The Composition and properties of Straight-Run and Mechanoactivated 360-400°C Distillate from Yakut Petroleum
Authors: Pikula P.A. , Golovko A.K. , Kamyanov V.F.
Published: July 2017

The group hydrocarbon composition of 360-400°C straight-run distillate of the petroleum from Talakanskoye oil-field (Yakutia − Republic of Saha) has been studied in detail using clathrate formation, liquid adsorption chromatography, thermodiffusion methods and mass spectrometric analysis of obtained thermodiffusion fractions. The fundamental physical constants of all isolated narrow hydrocarbon fractions were measured. The regularities of thermodiffusion separation of saturated hydrocarbons having different amounts of rings in molecules as well as the relations between properties and composition of the concentrates obtained were traced. It is established that a mechanoactivation of petroleum distillate leads to a change of its hydrocarbon composition, first of all to a decrease of its paraffin content, as well as to respective changes of its physicalchemical characteristics (to a decrease in pour point and an increase in density and viscosity values).

Криптовалюты - обзор, принцип работы, текущее использование, правовое регулирование
Authors: Закоржевский Вячеслав Владимирович
Published: July 2017

В настоящее время термин "криптовалюта" плотно укоренился как в повседневном лексиконе, так и в специализированной литературе. По сути за этим словом скрывается совокупность механизмов учёта, эмиссии и обмена. В отличие от электронных денег, криптографическая валюта не контролируется государством или организацией и не привязана к реальным деньгам. Так как подобные системы децентрализованы, то корректность работы обеспечивается с помощью т.н. цепочки блоков транзакций ("блокчейн"), построенной на основе криптографических алгоритмов. Этот механизм не позволяет подделать новую или предыдущие транзакции, скомпрометировать состояние счетов. На текущий момент существует бесчисленное множество криптовалют. Это обусловлено относительной простотой реализации подобных систем на базе открытых исходных кодов. Однако действительно популярных не так много – только несколько десятков подобных валют обладают рыночной капитализацией, превышающей 10 млн долларов. Капитализация самой известной и крупнейшей криптовалюты – BitCoin – на момент составления анонса составляла 12 млрд долларов. BitCoin стал широко использоваться в повседневной жизни. Ввиду высокой ликвидности и наличия большого количества бирж, любой человек без проблем можно обменять эиу криптовалюту на живые деньги. Настоящая статья представляет собой обзор криптовалют, как с теоретической, так и с практической точки зрения. Помимо предпосылок и причин роста популярности, отдельно будет затронута тема низкоуровневых механизмов функционирования, в первую очередь – "блокчейна". Отдельно рассмотрена возможность расширения блокчейна на другие финансовые операции. Так как рынки криптовалют не могут централизованно контролироваться и регулироваться, это создаёт серьёзные риски инвесторам, решившимся разместить часть средств в рассматриваемых инструментах. В статье рассмотрены существующие риски, а также приведен ряд инцидентов на биржах криптовалют, которые привели к колоссальным убыткам инвесторов и даже отразились на котировках. Несмотря на это, валюта BitCoin обладает значительным потенциалом для проведения валютных спекуляций, что привлекает множество людей поддерживать ликвидность. В связи с чем в статье представлен обзор возможностей инвестирования и анализ котировок ряда популярных криптовалют. Ввиду слабой освещённости данной тематики в российской научной литературе, автор полагает, что данная статья обладает практической значимостью и релевантностью.

Dinamika Forgiveness pada Istri yang Mengalami Kekerasan dalam Rumah Tangga (KDRT)
Authors: Puspita Dewi I Dewa Ayu Dwika , Hartini Nurul
Published: July 2017

Tujuan dari penelitian ini adalah untuk mengkaji dinamika forgiveness pada istri yang mengalami KDRT. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kasus instrumental. Kriteria subjek dalam penelitian ini yaitu seorang istri yang memiliki rentang usia 18-40 tahun, pernah mengalami KDRT oleh suami dan masih bertahan dalam perkawinan. Penelitian ini melibatkan tiga orang subjek yang pernah mengalami KDRT oleh suami dan masih bertahan dalam perkawinan selama 14-25 tahun. Penggalian data pada penelitian ini menggunakan teknik wawancara dan menggunakan teknik analisis tematik theory driven. Hasil dari penelitian menunjukan bahwa istri yang mengalami KDRT sulit memaafkan pelaku karena adanya ruminasi yaitu ingatan terhadap peristiwa KDRT yang pernah dialami dan adanya atribusi serta penilaian negatif mengenai pelaku. Dinamika forgiveness terjadi ketika istri yang mengalami KDRT mengubah dorongan untuk menghindari pelaku dan mengurangi dorongan membalas dendam terhadap pelaku ke arah yang positif melalui akomodasi. Meskipun pelaku meminta maaf atas kesalahannya, namun tidak ditemukan adanya empati untuk memaafkan pasangan. Penelitian ini menemukan adanya dorongan untuk berbuat baik kepada pelaku dengan melayani suami, meskipun demikian hal tersebut merupakan tugas dari seorang istri dalam rumah tangga yaitu untuk melayani suami.
Metode Kognitif dan Behavioral untuk Mengelola Stres dan Rasa Sakit Akibat Cedera pada Atlet Bola Basket
Authors: Kurniawan Afif
Published: July 2017

Cedera pada atlet seringkali terjadi dengan tingkat keparahan yang berbeda-beda. Demikian pula rasa sakit yang ditimbulkan. Selain mengalami nyeri dan pengobatan medis, aspek psikologis juga secara khas terlihat seperti munculnya rasa cemas, takut, nyeri yang tidak bisa dijelaskan munculnya, hingga hilangnya rasa percaya diri atlet itu sendiri. Performa mereka akan terganggu, bahkan dalam beberapa kondisi karir mereka bisa saja terhenti. Praktisi kesehatan mengungkapkan bahwa rasa sakit tidak hanya dapat dikendalikan dengan metode biochemical atau obat-obatan (drugs), melainkan dengan memodifikasi aspek motivasi dan proses kognisi (Sarafino, 2008). Ini merupakan cara pandang yang sedikit berbeda dan kompleks dimana para psikolog akan terlibat untuk melakukan teknik yang dilakukan untuk membantu klien mampu mengatasi rasa sakit dan rasa tidak nyaman terhadap stressor dengan lebih efektif. Di sisi lain, diharapkan penggunaan metode ini mampu mengurangi penggunaan obat atau zat kimia lain oleh subjek untuk mengatasi rasa sakit. Oleh karena itu, untuk meningkatkan kesiapan dan kesigapan atlet dalam mengatasi rasa sakit dan stress yang muncul selama bermain basket dan khususnya saat cidera perlu kiranya mengetahui bagaimana penggunaan metode behavioral dan kognitif ini dan pengaruhnya terhadap mereka. Penelitian ini bermaksud mengeksplorasi penggunaan metode behavioral dan kognitif untuk mengendalikan rasa sakit dan stress pada atlet bola basket pro.
Improved Forms for Controlling the Acrobot with Motors of Atypical Size Using Artificial Intelligence Techniques
Authors: Mier Gonzalo , de Lope Javier
Published: July 2017

An acrobot is a planar robot with a passive actuator in its first joint. The control problem of the acrobot tries to make it rise from the rest position to the inverted pendulum position. This control problem can be divided in the swing-up problem, when the robot has to rise itself through swinging up as a human acrobat does, and the balancing problem, when the robot has to maintain itself on the inverted pendulum position. We have developed three controllers for the swing-up problem applied to two types of motors: small and big. For small motors, we used the SARSA controller and the PD with a trajectory generator. For big motors, we propose a new controller to control the acrobot, a PWM controller. All controllers except SARSA are tuned using a Genetic Algorithm.
The Influence of Zeolite Amendment on Yield Performance, Quality Characteristics, and Nitrogen Use Efficiency of Paddy Rice
Authors: Chen Taotao , Xia Guimin , Wu Qi , Zheng Junlin , Jin Ye , Sun Dehuan , Wang Shu , Chi Daocai
Published: July 2017

The yield and environmental benefits of zeolite (Z) applied to agriculture are clear in many different types of soil for upland crops. However, limited information is available for lowland rice (Oryza sativa L.) production systems. A 2‐yr field experiment using a strip‐plot design was conducted to evaluate the impact of Z amendment on yield performance, quality characteristics, and nitrogen (N) use efficiency of paddy rice. Japonica rice (cv. Gangyu 6) was cultivated in a silty loam soil with N application (0, 52.5, 105.0, and 157.5 kg N ha−1) as whole plots and Z amendment (0, 5, 10, and 15 t Z ha−1) as strip plots. Compared with the paddy field without Z amendment, there was 14.2 to 35.8% higher potential postharvest residual soil mineral N and 20.1 to 44.6% higher exchangeable potassium when the upper 30 cm of the soil was amended with 5 to 15 t Z ha−1. Application of 5 to 15 t Z ha−1 increased applied N fertilizer use efficiency by 39.0 to 64.4% and N recovery efficiency by 20.7 to 85.2%, respectively. Milling, appearance, and eating quality traits were not affected by Z amendment, whereas rice protein content was increased by Z addition. The enhanced yield performance due to Z was mainly caused by improved essential plant‐available nutrients, which reduced ineffective tillers and produced more effective tiller number per square meter at harvest. In addition, these positive residual activities were maintained for at least an additional year after initial application in the lowland rice production system.
The Application of Radon for Mapping Open Fracture Networks in a Thin Vadose Zone

Core Ideas

Locating preferential pathways for infiltration is critical for contaminated fractured rock aquifers.

Mapping open fractures in buried bedrock formations has been marginally successful and costly.

Mapping at greater resolution and lower cost can be valuable for many fractured‐rock sites.

We used CR‐39 particle track 222Rn detector technology in a simple passive sampling design.

Our methodology is characterized by low cost and ease of deployment.

The use of naturally occurring tracers to elucidate subsurface flow and transport of water and gases through fractured vadose zones represents a powerful and inexpensive methodology for understanding geologic systems. Our study was conducted at Shepley's Hill, a highly fractured granite highland at the former Fort Devens military base. This study evaluated the applicability of using inexpensive, readily available passive Rn detectors to identify conductive structures (e.g., fractures and fracture networks) in fracture‐dominated vadose zones. Results from the Shepley's Hill study show a clear spatial correlation of elevated 222Rn concentrations emanating from fracture zones previously identified by independent geologic studies. At Shepley's Hill, the 222Rn concentrations measured from detector locations directly above bedrock fractures located within the Disc Golf Fracture Zone were almost exclusively the highest values measured in the study. Conversely, probes located above areas of less‐fractured bedrock and the Nona–Shep Fracture Zone showed relatively low 222Rn concentrations. These two observations provide strong supporting evidence that not all fractures are equal when it comes to their ability to transmit gas and, by inference, water into and out of the subsurface. Based on the results of this study, 222Rn is an environmental tracer capable of efficiently detecting major bedrock fracture sets in the vadose zone that readily transport gas and may be responsible for focusing water infiltration into contaminated aquifers.

Estética de la recepción e Historia de las ideas en el siglo XVIII. La virtus y el honestum ciceronianos en el “honor nobiliario“ de Montesquieu y la “educación cívica“ de Gaspar Melchor de Jovellanos
Authors: Martín Javier Espino
Published: July 2017

A través de la metodología de una selección de teóricos de la“estética de la recepción”, pretendemos analizar la interrelaciónentre el “horizonte de expectativas” (en terminología deGadamer y de Jauss) de Marco Tulio Cicerón, con el de losintelectuales ilustrados Montesquieu y Gaspar Melchor deJovellanos. A partir de ahí, pretendemos rellenar los “vacíos”(según la terminología de Iser), o los misunderstandings (enpalabras de Hirsch) que la lectura ilustrada hace de la éticapolítica ciceroniana en el término concreto de la “virtud” y la“honestidad”. Así pues, desarrollaremos estos conceptos segúntoda la cosmovisión ciceroniana en contraste con la ilustradade Montesquieu y Jovellanos, y resaltaremos, de este modo,aquellos puntos de cambio y aquellos de enraizamiento en elpensamiento del propio Cicerón. En definitiva, responderemosa la pregunta de hasta qué punto el rhetor romano condicionó laconcepción política de la virtud y honestidad tanto en el ilustradofrancés como en el español (en los que también se tendrá encuenta la destacada interferencia del empirismo inglés), a lavez que, de qué forma estos autores “modernos” readaptaron ytransformaron el pensamiento del “clásico” según sus propios“horizontes de expectativas”.

Metafísica de la violencia y de la paz. Análisis agustiniano de una definición de Paul Gilbert
Authors: Rosales Meana Diego I.
Published: July 2017

En este trabajo intentaré trazar los lineamientos básicos de una metafísica de la violencia y de la paz en Paul Gilbert y Agustín de Hipona. Para ello, explicitaré los postulados agustinianos sobre los que descansa una definición Gilbert da de la violencia en su libro La paciencia de ser. La definición de Gilbert se pondrá a prueba en tres pasos. En primer lugar, exploraré lo que implica hablar de la violencia en metafísica concebida ésta como una «filosofía primera». En segundo lugar, recuperaré la fenomenología que Agustín de Hipona elabora principalmente en De libero arbitrio. En tercer lugar analizaré la libertad política y su sustitución a través de la noción de «legalidad». De este modo, la violencia quedará caracterizada como la renuncia a lo propiamente político, como la afirmación unilateral de la libertad individual y, por lo tanto, la negación de esa misma libertad.
Pensamiento, voluntad y juicio: las condiciones mentales de la acción política en la filosofía de Hannah Arendt
Authors: Leal Yuliana , Botero Jerónimo
Published: July 2017

En The Life of Mind, Hannah Arendt  sostiene que el pensamiento crítico activa el ejercicio del juicio reflexionante. Este tipo de juicio no opera de manera deductiva como en el caso de los juicios determinantes que subsumen un particular bajo una regla general, sino que analiza un acontecimiento particular y es a partir de este último que se revela una generalidad. La pensadora considera que los juicios políticos y morales son juicios reflexionantes que conducen a los individuos a tener el valor de pensar por sí mismos sin recurrir a las reglas sociales imperantes. El ejercicio del pensamiento crítico y el juicio reflexionante es fundamental para fomentar la libertad de actuar políticamente. El propósito de este artículo es defender la hipótesis de que el pensamiento crítico, la voluntad como espontaneidad y el juicio reflexionante son las condiciones mentales que hacen posible la vida política de los seres humanos desde la perspectiva de Arendt. Palabras Claves: Arendt, Pensamiento, Juicio, Acción.
Ramón Rodríguez (coord). Ser y tiempo de Martin Heidegger. Un comentario fenomenológico
Authors: Abalo Cea Francisco
Published: July 2017

Este nuevo comentario sobre Ser y Tiempo constituye un esfuerzo colaborativo que toma la tarea de servir de ayuda al lector—y no sólo al estudioso especializado— en el afán por comprender con mayor profundidad y claridad el sentido de los análisis que Heidegger va desarrollando en su obra mayor y más célebre (cf. p.11).  Tarea nada de fácil dado que, a primera vista, esta obra se presenta en un intrincado estilo expositivo y se expresa mediante una compleja terminología; dificultades que, sin embargo, no obstan para considerarla como una de las obras filosóficas centrales del siglo XX, cuya influencia intelectual sigue siendo decisiva hoy.
La composicionalidad del lenguaje revisitada
Authors: Destefano Mariela
Published: July 2017

En este trabajo intentaré mostrar que el lenguaje es composicional desde la perspectiva del programa minimalista. Desde este enfoque adoptaré la noción de “lengua-I”.Específicamente, intentaré sostener que si el minimalismo es correcto, el producto de la lengua-I es composicional en virtud de restricciones generales de arquitectura cognitiva y restricciones intrínsecas al mecanismo computacional de la lengua-I. Mi argumento puede entenderse como una inferencia a la mejor explicación. La mejor explicación de que la lengua-I, en tanto sistema de expresiones que sirven de instrucciones semánticas para la interfaz conceptual-intencional, genere computacionalmente esas instrucciones y responda óptimamente a las condiciones de interfaz es, en parte, atribuyéndole composicionalidad semántica a dichas expresiones.

In 1780, Philadelphia suffered an unusual outbreak of hemorrhagic fever, which years later was identified as dengue (1). One hundred years later, in Memphis, 1500 people died from yellow fever, which caused residents to abandoned the city (2). Even though these stories may seem anecdotes, they show how dramatic hemorrhagic arbovirus outbreaks can be.The tropic host arboviruses such as Chikungunya (CHIKV), Dengue, and Zika (ZIKV); but there are others, such as Mayaro, Oropuche, and Bussuquara, among others, which have still not been studied in depth by the public health systems of our countries.

ABSTRACTObjective. To determine the associations of BoLA DRB3.2 alleles present in Holstein and BON x Holstein cattle to production and milk quality traits in a dairy herd of Antioquia, Colombia. Materials and methods. Ninety-one cows, 66 Holstein and 25 BxH, were genotyped for the BoLA DRB3.2 gene, through PCR-RFLP technique. Furthermore, the association of the alleles of the gene BoLA DRB3.2 with milk yield (PL305), fat yield (PG305), protein yield (PP305) fat percentage (PGRA) and protein percentage (PPRO) were determined, using a general linear model. Results. Twenty-seven BoLA DRB3.2 alleles were identified; the most frequent alleles in Holstein were: BoLA DRB3.2*23, 22, and 24 with frequencies of: 0.159, 0.129, and 0.106, respectively and the most frequent alleles in BxH were: BoLA DRB3.2*23, 24 and 20 with frequencies of: 0.20, 0.140, and 0.120, respectively. Associations of BoLA DRB3.2 alleles with production and milk quality traits were also determined. In Holstein cows the BoLA DRB3.2*36 allele was associated with low PL305 (p≤0.01), high PGRA in multiparous cows (p≤0.05) and high PG305 in primiparous cows (p≤0.01). The BoLA DRB3.2*33 allele was associated with increased in the PPRO in multiparous cows (p≤0.01). In BXH cows only the BoLA DRB3*19 allele was associated with high PGRA (p≤0.05). Conclusions. The gene BoLA DRB3.2 shows high polymorphism in both groups; Holstein and BxH and some of its allelic variants were associated with production and milk quality traits

ABSTRACTObjective. Characterize the follicular dynamics and luteal growth and regression pattern of multiparous (MB) and heifer (BH) Murrah buffaloes in Colombian tropical conditions. Material and methods. Ten MB and ten BH were synchronized with a progesterone-releasing intravaginal device. No artificial insemination was performed during the estrous and daily ultrasound examinations were performed 15 days later to determine the number and diameter of the structures present in both ovaries in the subsequent natural estrous cycle. The Student’s T test was used to evaluate differences between MB and BH. All data are presented as mean ± standard deviation. Results. The length of the estrous cycle was 22.00±4.50 days for MB and 22.00±2.70 days for BH. Follicular growth occurs in one (n=1; 5.89%), two (n=14; 82.35%) or three waves (n=2; 11.76%). The first wave initiated the day after ovulation with the recruitment of 8.33±2.06 and 10.00±2.72 follicles in MB and BH, while the second wave started on day 11.00±2.00 and 10.50±2.82, presenting 8.37±2.26 and 8.00±1.51 follicles. The third wave began on day 16.21±3.10 showing 6.50±1.70 follicles, only BM had three waves. The maximum luteal diameter was 19.58±4.16 mm and 17.74±3.32 mm respectively. There were no significant differences between the groups for these variables. Conclusions. These results show that the follicular development in buffaloes occurs in waves, where two waves is the most common pattern, as previously reported by other authors.

ABSTRACTObjective. The purpose of this study was to characterize a population of domestic pig (Sus scrofa domestica) in Cereté, Córdoba, using 20 microsatellite; calculate heterozygosity per locus and average heterozygosity. Materials and methods. Hair samples were collected from 62 specimens. DNA was extracted by proteinase K digestion and phenol-chloroform purification. Information from 20 microsatellites was selected out of those recommended for swine biodiversity studies. PCR products were separated by a vertical polyacrylamide gel electrophoresis. The bands were visualized by staining with silver nitrate. Results. All microsatellites used were polymorphic. Between 3 (SW1067) and 15 (IFNG) alleles were detected with an average number of 6.7 and a total de 134 alleles. The average expected and observed heterozygosities were 0.5278 and 0.5479, respectively. PIC values ranged between 0.1999 and 0.8300 for loci SW1067 and SW911, respectively. Conclusions. Levels of observed and expected heterozygosity found in the present study indicate that the domestic pig (Sus scrofa domestica) in Córdoba Cereté show high degree of genetic variability
Foraging density for squirrel monkey Saimiri sciureus in two forests in Puerto Lopez - Colombia
Authors: Astwood R Jorge , Rodríguez P José , Rodríguez-C Karen
Published: July 2017

ABSTRACTObjective. Forest remnants were analyzed to determine the density of squirrel monkeys (Saimiri sciureus) and the degree of alteration of the forest, by selecting areas for the conservation and maintenance of the species in natural environments. Materials and methods. Linear transects were conducted on two wooden fragments, “La Reforma” and “Campo Hermoso” farms (Puerto Lopez, Meta, Colombia), recording sightings of squirrel monkeys and identifying the tree species used by the primates. Results. The fragments studied correspond to trails at the edge of water bodies with low connectivity. Highest density values were observed on the second transect of La Reforma, a possible consequence of an overcrowding phenomenon due to the high degree of isolation of the fragment. The species preferentially used as refuge and food source were: Bellucia grossularioides, Eugenia jambos, Inga alba, Mauritia flexuosa, Pseudolmedia laevis and Rollinia edulis. Conclusions. The phenology of the plant species allows for a dynamic food supply, considering the constant availability of food for the primates. Therefore, despite the evident ecological problem of these forests, it is possible to use active restoration programs to strengthen the existing dynamics and balance the biogeochemical dynamics of the ecosystem, so that socioeconomic human activities are not in conflict with conservation efforts and vice versa.

ABSTRACTObjective. Assessment the total concentration of mercury in the liver and feathers of Pelecanus occidentalis of the Cispata bay, Colombia. Materials and methods. Mercury concentrations in liver and feather of Pelecanus occidentalis residents in the Cispata bay – Colombia were evaluated by digestion with an acidic mixture of H2SO4–HNO3 and KMnO4 to eliminate organic matter. The concentration of mercury was determined by the Atomic Absorption - Cold Vapor method (CVAAS). Results. Total mercury levels found in this study were higher in feathers (0.31-9.17 mgHg/kg) than in the liver (0.63–6.29 mgHg/kg), being higher than those reported in other seabirds studies. Conclusions. The high levels of total mercury in feathers and liver can be explained by the feeding habits of the organisms under study, showing the utility of feathers as a potential non-invasive tool for the monitoring of the ecosystem and thereby preventing the sacrifice of specimens

Published: July 2017

ABSTRACTObjective. To study the trophic ecology of Saccodon dariensis in the Peñoles and El Cardal streams, Guatape River mid-basin, Magdalena River Basin, Colombia. Materials and methods. To compare differences in size between individuals from the two streams in terms of hydrologic periods, oral polymorphisms or sexes, an analysis of variance was conducted (ANOVA). Volume percentages, frequency of occurrence and the food importance index (FII) were determined; a principal component analysis (PCA) and an ANOVA was carried out to determine the diet differences between streams, climatic periods, oral polymorphism, sexes and developmental states, as well as a Mann-Whitney pairwise comparison test for each food category. Results. A significant difference was found in size between individuals of the two streams with different oral polymorphism. Algae are the most important food item (FII: 91.9%), followed by Trichoptera and insect remains (FII: 4.3%), and vegetal material (FII: 1.8%). The PCA did not indicate significant differences in diet between streams, climatic periods, oral polymorphisms, sexes or developmental states, but the ANOVA and Mann-Whitney pairwise comparison test indicated differences in oral morphotype, where individuals with a straight mouth consumed more vegetal material. We also observed different proportions in consumption of different algae genera, and increased consumption of insects in ontogeny, this being higher in individuals with a straight mouth. Conclusions. The species is algaevorous. The oral morphotypes of S. dariensis may be related to a trophic polymorphism that confers different trophic habits and differential access to the items that constitute their diet.

Published: July 2017

ABSTRACTObjective. Measure the productive parameters of Holstein-Friesian females from weaning to 470 days old, comparing feeding through sugarcane silage (SCS) and corn silage (CS) in a concentrated fodder ratio of 70:30. Materials and methods. Twenty-eight post-weaning calves were used, with an average age of 80±16 days old and an initial weight of 79.5±12.9 kg. The T-Student test was used for the comparison of means, where calves were divided into two groups of 14, one for each treatment. The body weight BW (kg), wither height WH (cm), body condition BC (1 to 5 scale), daily weight gain DWG (kg) and feed conversion FC (kg) was measured every 30 days. Results. Differences were found between treatments, where heifers fed with SCS showed better BC (3.12), FC (7.4) as compared to the CS treatment. No significant differences were found in terms of DWG (0.666 and 0.743 kg/d). Conclusions. Feeding based on sugarcane silage allows for an improved body condition and feed conversion of animals having with this an acceptable and cost-effective production performance in the raising of dairy replacements.
