ABSTRACT

Bamboo (Bambusa sp.) is a grass species with high potential for exploitation, however, this raw material is easily attacked by xylophagous agents such as Coleoptera. The objective of this study is thus to analyse the presence of wood-boring beetles associated with Bambusa sp. in Alta Floresta, Mato Grosso, Brazil. The study was carried out in a bamboo plantation, from August 2016 to July 2017. Two models of ethanolic traps were used, PET Santa Maria and ESALQ-84. Three families of wood-boring beetles were observed in this study: Bostrichidae, Cerambycidae and Curculionidae. 2,144 individuals were identified, belonging to 19 species, in four subfamilies and 11 tribes, and the species Xyleborus affinis was the most frequently collected. Thus, this study constitutes an important contribution to the knowledge of coleoborers associated with bamboo plantations, with the registration of the occurrence of species, as well as contributing to the knowledge of the entomofauna associated with species cultivated in the Southern Amazon.

ABSTRACT

Abstract The present paper addresses the feeding activity of Trachinotus cayennensis, collected in Lençóis Bay (1°18'S - 1°19'S; 44°51'W - 44°53'W) on the western coast of the state of Maranhão, Brazil. Sampling was conducted between June 2012 and June 2013 using driftnets with stretch mesh sizes from 95 to 100 mm. A total of 205 individuals (114 females and 91 males) were analyzed. Statistically significant differences in the sex ratio were found in June, September and December 2012. Food items were analyzed based on frequency of occurrence and volumetric method, with the subsequent calculation of the alimentary importance index. Three size groups were defined to determine possible ontogenetic changes in eating habits based on the size range of the individuals collected: I (˂ 29 cm), II (29.1 to 37.0) and III (≥ 37.1). Eleven food item categories were identified: mollusks, polychaetes, crustaceans, nematodes, insects, algae, bryozoans, ophiuroids, fishes, vegetal matter and sediments. The variety of items in the diet of T. cayennensis indicates considerable feeding plasticity and opportunistic behavior. Seasonal variations influenced the feeding pattern of the species, with greater feeding activity in the dry season. The considerable availability of resources in estuarine habitats of the western coast of Maranhão constitutes another factor that influences the feeding behavior of this species.


Resumo Atividade alimentar do pampo Trachinotus cayennensis (Cuvier 1832) (Perciformes, Carangidae) em estuários na costa ocidental do Maranhão, Brasil. O presente trabalho descreve a atividade alimentar do Trachinotus cayennensis , coletado na Baía de Lençóis (1°18'S - 1°19'S; 44°51'W - 44°53'W) na costa oeste do Maranhão. Amostragens foram realizadas entre junho de 2012 e junho de 2013, utilizando redes de emalhar à deriva com tamanho de malha de 95 a 100 mm. Foram analisados ​​205 indivíduos (114 fêmeas e 91 machos). Encontraram-se diferenças estatisticamente significativas na proporção sexual nos meses de junho, setembro e dezembro de 2012. Os itens alimentares foram analisados ​​com base na frequência de ocorrência e utilizando o método volumétrico, com o subsequente cálculo do índice de importância alimentar. Três grupos de tamanho foram definidos para determinar possíveis mudanças ontogenéticas nos hábitos alimentares com base na faixa de tamanho dos indivíduos coletados: I (˂ 29 cm), II (29,1 a 37,0) e III (≥ 37,1). Foram identificadas 11 categorias de alimentos: moluscos, poliquetas, crustáceos, nematoides, insetos, algas, briozoários, ophiuro, peixes, matéria vegetal e sedimentos. A variedade de itens na dieta de T. cayennensis indica uma plasticidade alimentar considerável e um comportamento oportunista. As variações sazonais influenciaram o padrão alimentar da espécie, com maior atividade de alimentação na estação seca. A considerável disponibilidade de recursos nos habitats estuarinos da costa oeste do Maranhão constitui outro fator que exerce influência sobre o comportamento alimentar desta espécie.

ABSTRACT

The characterization of demographic and epidemiologic aspects of dogs and cats domiciled in households in Barbacena, Minas Gerais, Brazil, is imperative to understand the dynamics of animal populations for the purpose of planning actions in public health and zoonosis control. A total of 840 semi-structured questionnaires were applied. Respondents were randomly selected owners from urban and rural areas. The results revealed 0.22 per capita dog, 0.051 per capita cat, 0.81 dog per house, and 0.19 cat per house. Dogs were present in 51.3% of the properties, distributed as 77.9% in rural and 48.6% in urban areas (47.3% in houses and 16.5% in apartments). The average age was 4.47 years for dogs, with odds male/female of 1.58. For the cats, the average age was 2.9 years and odds male/female of 0.91. The mortality rate before weaning was 13.4% for dogs and 22.8% for cats. The breeding purpose rate was 68.3% of dogs while cats as pets were 99.4%. The main form of animals acquisition was by donation (65.8%) and only 4.14% came from other cities. About the type of feeding, 55.9% of dogs and 46.3% of cats ate manufactured products. Only 29.6% of dogs and 16.5% of cats had some type of veterinary care. The rabies vaccination covers 89.2% and 68.1% of dogs and cats, respectively. Castration or use of contraceptive was found in 18.7% of dogs and 17.9% of cats. These numbers could be used for measures of control in dogs and cats population of the municipality, as well in programs for the control of zoonotic diseases.

ABSTRACT

The objective of this study was to assess the prevalence of barriers to interferon treatment in a population of HIV/HCV coinfected patients. A cross-sectional study was conducted at two AIDS Outpatient Clinics in Brazil. The study included all HIV infected patients followed at these institutions from January 2005 to November 2007. Medical records of 2,024 HIV-infected patients were evaluated. The prevalence of anti-HCV positive patients among them was 16.7 percent. Medical records of HCV/HIV coinfected patients were analyzed. 189 patients with the following characteristics were included in our study: mean age 43 years; male gender 65 percent; former IDUs (52 percent); HCV genotype 1 (66.4 percent); HCV genotype 3 (30.5 percent); median CD4+ T cell count was 340 cells/mm³. Among 189 patients included in the analyses, only 75 (39.6 percent) were considered eligible for HCV treatment. The most frequent reasons for non-treatment were: non-compliance during clinical follow-up (31.4 percent), advanced HIV disease (21.9 percent), excessive alcohol consumption or active drug use (18.7 percent), and psychiatric disorders (10.1 percent). CONCLUSIONS: In Brazil, as in elsewhere, more than half of HIV/HCV coinfected patients (60.4 percent) have been considered not candidates to received anti-HCV treatment. The main reasons may be deemed questionable: non-adherence, drug abuse, and psychiatric disease. Our results highlight the importance of multidisciplinary teams to optimize the access of coinfected patients to HCV treatment.

ABSTRACT

During pregnancy and protein restriction, changes in serum insulin and leptin levels, food intake and several metabolic parameters normally result in enhanced adiposity. We evaluated serum leptin and insulin levels and their correlations with some predictive obesity variables in Wistar rats (90 days), up to the 14th day of pregnancy: control non-pregnant (N = 5) and pregnant (N = 7) groups (control diet: 17 percent protein), and low-protein non-pregnant (N = 5) and pregnant (N = 6) groups (low-protein diet: 6 percent). Independent of the protein content of the diet, pregnancy increased total (F1,19 = 22.28, P < 0.001) and relative (F1,19 = 5.57, P < 0.03) food intake, the variation of weight (F1,19 = 49.79, P < 0.000) and final body weight (F1,19 = 19.52, P < 0.001), but glycemia (F1,19 = 9.02, P = 0.01) and the relative weight of gonadal adipose tissue (F1,19 = 17.11, P < 0.001) were decreased. Pregnancy (F1,19 = 18.13, P < 0.001) and low-protein diet (F1,19 = 20.35, P < 0.001) increased the absolute weight of brown adipose tissue. However, the relative weight of this tissue was increased only by protein restriction (F1,19 = 15.20, P < 0.001) and the relative lipid in carcass was decreased in low-protein groups (F1,19 = 4.34, P = 0.05). Serum insulin and leptin levels were similar among groups and did not correlate with food intake. However, there was a positive relationship between serum insulin levels and carcass fat depots in low-protein groups (r = 0.37, P < 0.05), while in pregnancy serum leptin correlated with weight of gonadal (r = 0.39, P < 0.02) and retroperitoneal (r = 0.41, P < 0.01) adipose tissues. Unexpectedly, protein restriction during 14 days of pregnancy did not alter the serum profile of adiposity signals and their effects on food intake and adiposity, probably due to the short term of exposure to low-protein diet.

ABSTRACT

Las alteraciones de la articulación temporomandibular son frecuentes en la practica clinica odontológica. Esta disfunción tiene variados factores etiológicos, tales como deficiencia de la oclusión, alteraciones biomecanicas y anatomofisiológicas, entre otras. Evaluamos 20 radiografias panoramicas de mandibula, de individuos entre 21 y 77 a¤os de edad. Medimos algunos parametros del proceso condilar y de la rama de la mandibula. Estudiamos las radiografias en un negatoscopio, efectuandose las medidas con una caliper digital. Se utilizó el programa estadistico SPS 10.0, realizandose un estudio descriptivo piloto. La mayoria de los diametros del proceso condilar fueron mayores en las mujeres, asi el diametro vertical izquierdo, ( C4), con valores de 19,7 mm en los hombres y 20,3 mm en las mujeres, en cambio, el diametro vertical (R3) de la rama de la mandibula fue mayor en los hombres con un valor 43,1 mm y en las mujeres 38,8 mm, en la rama derecha; la rama izquierda tuvo un valor en los hombres de 39,6 mm y 38,6. mm en las mujeres. Estas diferencias podrian causar problemas en la masticación y diferencias en la mordida de los individuos, alterando la biomecánica de la articulación témporomandibular que contribuye a la disfunción y dolor que frecuentemente relatan los individuos.

ABSTRACT

La ubicación de los forámenes nutricios en los huesos húmero, ulna y radio ha sido descrita de forma general. Con el propósito de complementar la información sobre estos forámenes, estudiamos su ubicación, nivel de posición del foramen en relación con la epífisis distal (húmero) y epífisis proximal ( ulna y radio) y longitud del surco en el foramen. Estos parámetros fueron correlacionados con la longitud del hueso. Utilizamos 90 huesos secos, en perfectas condiciones de conservación, 30 de cada uno, de individuos adultos, de ambos sexos, procedentes del Museo de la Unidad de Anatomía, Facultad de Medicina, Universidad de La Frontera, Temuco, Chile. El número más frecuente de forámenes nutricios encontrado en la mayoría de las muestras, fue 1. En el húmero derecho fue encontrado en su cara antero medial en 93,3 por ciento de los casos y en el izquierdo en un 73,3 por ciento. En la ulna derecha se presentó en su cara anterior en un 80 por ciento de los casos y en la izquierda en un 100 por ciento. En el radio derecho se localizó en su cara anterior en 93,3 por ciento y en el izquierdo en un 80 por ciento. En el húmero derecho se localizó en promedio a 134,6 mm (D.S±14), respecto a su epífisis distal y en el izquierdo a 139,2 mm (D.S± 22,5); en la ulna derecha se localizó en promedio a 98,5 mm (D.S± 14,4) respecto a su epífisis proximal y en la izquierda a 100,1mm (D.S± 12,4); en el radio derecho se localizó en promedio a 84,9 mm (D.S± 8,8) respecto a su epífisis proximal y en el izquierdo a 79,6 mm (D.S&± 7,8). Los datos obtenidos pueden ser utilizados como referencia en la anatomía quirúrgica del miembro superior.

ABSTRACT

The short chain fatty acids (SCFA) are the best nutrients for the colonocytes. Glucose is poorly used as a fuel but may be transformed into SCFA by colonic bacteria. The aim of this study was to investigate the effect of SCFA or glucose on experimental colitis. Colitis was induced in 30 Wistar rats by colonic instillation of 4 percent acetic acid. Five days later they were randomized to receive twice a day colonic lavage containing saline (controls, N = 10), 10 percent hypertonic glucose (N = 10) or SCFA (N = 10) until day 8 when they were killed. At autopsy, the colon was removed and weighed and the mucosa was evaluated macro- and microscopically and stripped out for DNA assay. Data are reported as mean + or -SD or median [range] as appropriate. All animals lost weight but there was no difference between groups. Colon weight was significantly lower in the SCFA group (3.8 + or - 0.5 g) than in the control (5.3 + or - 2.1 g) and glucose (5.2 + or - 1.3 g) groups (PP<0.05). Macroscopically, the severity of inflammation was less in SCFA (grade 2 [1-5]) than in control (grade 9 [4-10]) and glucose-treated (grade 9 [2-10]) animals (P<0.01). Microscopically, ulceration of the mucosa was more severe in the glucose and control groups than in the SCFA group. The DNA content of the mucosa of SCFA-treated animals (8.2 [5.0-20.2] mg/g of tissue) was higher than in glucose-treated (5.1 [4.2-8.5] mg/g of tissue; P<0.01) and control (6.2 [4.5-8.9] mg/g of tissue; P<0.05) animals. We conclude that SCFA may enhance mucosal re-epithelialization in experimental colitis, whereas hypertonic glucose is of no benefit

ABSTRACT

Os autores realizaram um estudo do estado nutricional por antropometria num grupo de 405 crianças de 3 a 72 meses de idade, residentes na área urbana da cidade de Cáceres - Regiäo do Polonoroeste no Estado do Mato Grosso. Mediante a aplicaçäo de um questionário ao responsável pela criança, pesquisou-se a ocorrência de diarréias na mesma populaçäo. O objetivo do estudo foi verificar a prevalência de desnutriçäo e a freqüência de diarréias nessas crianças. Utilizaram-se as classificaçöes propostas por GOMEZ e WATERLOW para verificar a prevalência e a natureza da desnutriçäo. Foi verificado que a desnutriçäo ocorreu em 33% das crianças segundo a classificaçäo de GOMEZ. Segundo os critérios de WATERLOW a forma de desnutriçäo de maior proporçäo encontrada foi a pregressa, com percentual de 36%. Entre as crianças desnutridas a freqüência de diarréias foi de 47% sendo a relaçäo entre diarréia e desnutriçäo estatisticamente significante

ABSTRACT

Entre 1972 e 1986, do total de 1.780 pacientes com uveíte, 6 pacientes (0,4%) foram diagnosticados como portadores de oftamia simpática e tratados no centro de uveítes da Escola Paulista de Medicina (Hospital Säo Paulo), Brasil. Dois eram do sexo feminino, sendo três brancos, um preto, um índio e um oriental. A idade média dos pacientes foi de 31 anos (variando de 5 a 75 anos) e o tempo decorrido entre o trauma (acidental em 4 e cirúrgico em 2) foi de 2 a 8 meses em 5 pacientes e de vários anos no sexto. Cinco dos 6 olhos acidentados apresentaram mesmo no final do tratamento amaurose neste olho e o outro paciente C.D. a 1 metro. No olho näo traumatizado 3 pacientes terminaram com visäo inferior a 20/200. A inflamaçäo estava clinicamente ausente em 2 dos olhos traumatizados tendo o diagnóstico sido confirmado por exame histológico em parte dos olhos examinados (4/6). Todos os pacientes receberam corticóide sendo que ciclofosfamida e clorambucil foram associados a dois pacientes distintos
