ABSTRACT
ABSTRACT: This study sought to evaluate the number of bruises on bovine carcasses and their relationship with loading rates in different truck models. Bruising percentages in the hindquarter, forequarter and short rib regions were evaluated. The space occupied on the truck by each animal in m² was defined as the Practiced area, obtained by dividing the body area by the number of males and females transported in straight trucks (10.60 x 2.40 m) and livestock trailers (14.80 x 2.60 m), 240 and 168, and 120 and 93, respectively, and 80 males in a straight truck with trailer configuration (17.50 x 2.60 m). The minimum area occupied by the animals was assessed according to the Farm Animal Welfare Council (FAWC) and Animal Welfare Advisory Committee (AWAC). The data was analyzed in a completely randomized design and included two sex classes, three carcass regions and three truck types. For males, the minimum areas (m²) calculated by the FAWC and AWAC were smaller (1.37 and 1.29 m², respectively) for the straight truck. The straight truck with trailer configuration had the lowest (P=0.0025) bruising index in the forequarter region (15.1%) and the highest (P=0.047) in the short rib region (30.5%). Females transported in the livestock trailer had a higher (P<0.001) percentage of bruises in the forequarter region (51.7%). There was a relationship between the high bruising rates and the loading rate Practiced for the males. Estimations made by the AWAC are close to those practiced in the upper Pantanal region of Mato Grosso do Sul, Brazil.
RESUMO: Este estudo teve por objetivo avaliar o número de hematomas em carcaças de bovinos e suas relações com as taxas de lotação em diferentes modelos de carrocerias. Foi avaliada a porcentagem de hematomas na região do traseiro, dianteiro e ponta da agulha (PA). O espaço ocupado por cada animal em m² foi definido como área Praticada, sendo obtido pela divisão da área da carroceria pelo número de machos e fêmeas transportados nos caminhões truck (10,60 x 2,40 m) e carreta baixa (14,80 x 2,60 m); 240 e 168; 120 e 93, respectivamente, e 80 machos em caminhão romeu e julieta (17,50 x 2,60 m). Avaliou-se a área mínima ocupada por animal pela Farm Animal Welfare Council (FAWC) e Animal Welfare Advisory Committee (AWAC). Os dados foram analisados em um delineamento inteiramente casualizado sendo duas classes sexuais, três regiões da carcaça e três tipos de caminhões. Para machos, as áreas mínimas (m²) pela FAWC e AWAC foram menores (1,37 e 1,29 m², respectivamente) para o caminhão truck. O caminhão romeu e julieta apresentou o menor (P=0,0025) índice de hematomas na região dianteiro (15,1%) e o maior (P=0,047) na PA (30,5%). As fêmeas transportadas no caminhão carreta baixa, apresentaram maior (P<0,001) porcentagem de hematomas na região dianteiro (51,7%). Houve relação entre os altos índices de hematomas e a taxa de lotação Praticada para o caminhão carreta baixa e romeu e julieta para machos. As determinações realizadas pela AWAC estão próximas das Praticadas no Alto Pantanal sul-mato-grossense.
ABSTRACT
RESUMEN: El defecto más común del prosencéfalo es la holoprosencefalia (HPE), caracterizada por ausencia en la división del prosencéfalo. La holoprosencefalia tiene una prevalencia de 1/10.000 en recién nacidos; la ciclopía de 1/100.000 nacidos y la agnatia asociada a holoprosencefalia de 0,8 a 10 %. El objetivo fue describir las características morfológicas e histopatológicas de un feto humano con holoprosencefalia y sus malformaciones asociadas. Se estudió un feto masculino. Se le realizó microdisección bajo el estereomicroscopio, toma de microfotografías con cámara AxioCam y software AxioVision 4.8, y estudio histopatológico. La edad gestacional estimada fue de 12,4-13,2 semanas, encontrándose como hallazgos la HPE semilobar asociada a ciclopía, esbozo oral hipoplásico sin apertura oral, cubierta por una membrana y ausencia de labios. El estudio histopatológico reportó: ojo con lente, retina y córnea únicos; en la cara, probóscide con cartílago tubular en formación asociado a mesénquima y cubierta muscular esquelética, y cavidad oral pequeña, circunscrita por mandíbula hipoplásica conformada por cartílago. Se revisa la literatura y se reafirma la necesidad de estudio multidisciplinario de esta patología para mejorar su comprensión.
SUMMARY: The most common defect of the forebrain is holoprosencephaly (HPE), characterized by absence in the forebrain division. Holoprosencephaly has a prevalence of 1 / 10,000 in newborns; the cyclopia of 1 / 100,000 births and the agnathia, in a series of cases of holoprosencephaly ranges from 0.8 to 10 %. The objective was the description of the morphological and histopathological characteristics of fetus with holoprosencephaly and its associated malformations. A male fetus was studied. Microdissection was performed under the stereomicroscope, taking microphotographs with AxioCam camera and AxioVision 4.8 software, and histopathological study. The estimated gestational age was 12.4-13.2 weeks, the findings were semilobar HPE, associated with cyclopia, hypoplastic oral outline without buccal opening, covered by a membrane and lips absence. The histopathological study reported: eye with lens, retina and cornea only; in the face, proboscis with tubular cartilage in formation associated with mesenchyme and musculoskeletal sheath, and small oral cavity, delimited by hypoplastic mandible conformed by cartilage. The literature is reviewed and reaffirmed the need for multidisciplinary studies of this disease to improve their understanding.

En las últimas décadas se ha evidenciado el impacto de laactividad física sobre la salud en diferentes poblaciones.Pero se desconoce qué impacto tienen las actividades físicasvigorosas y sistematizadas sobre la salud de los adultos.Esta investigación tuvo por objeto valorar los niveles deaptitud física de los participantes de fútbol, adulto maduro,perteneciente a la liga de veteranos de la provincia deCatamarca mayores de 50 años.Se utilizo un modelo de investigación explicativa, conun diseño no experimental, transeccional. Participaron delgrupo de fútbol de veteranos 58 deportistas, edad 52 + 3años, y del grupo control 37 personas sedentarias, de 52 + 5años. Fueron evaluados en Aptitud Física (AF), Resistencia,ergoespirometria; Fuerza Potencia test de saltar y alcanzar(SyA); Indice de Masa Corporal (BMI). Los resultadosencontrados, demuestran que el grupo de fútbol, tienemayores valores en los componentes de la aptitud física,resistencia y fuerza potencia que el grupo control, siendoestas diferencias significativas. En las variables de índice demasa corporal los valores son significativamente menores enel grupo de fútbol de veteranos, que en el grupo control. Denuestros resultados podemos concluir que los jugadores defútbol veteranos tienen una buena aptitud física.
In the last decades, the impact of physical activity on health has been shown in differentpopulations. However, the impact of energetic and systematized physical activities onadult health is unknown. The objective of this research was to assess the levels of physicalfitness of adult mature participants aged over 50 in a veteran soccer league in the provinceof Catamarca.A cross-sectional explicative research model with non-experimental design was used.In the soccer group, there were 58 veteran sportsmen, aged 52 + 3; in the control groupthere were 37 sedentary people aged 52 + 5. They were evaluated in Physical Fitness,Resistance, ergospirometry, Strength Power jump and reach test (J&R); Body Mass Index(BMI). Results found show that the soccer group has higher values in the componentsPhysical Fitness, Resistance, and Strength Power than the control group, with significantdifferences. As regards the BMI variable, values are significantly lower for the veteran soccergroup than for the control group. From our results we can come to the conclusion that theveteran soccer players have good physical fitness.
