| Abstract Abstract: We used skeletochronology to compare age, size, reproductive parameters and growth patterns of two related, anuran amphibians from Northern Argentina: Leptodactylus bufonius(n=69) andL. latinasus(n=56), in order to better understand their coexistence in syntopy. Previous studies showed that the two species overlap in their dietary requirements and utilize the same habitats for feeding and breeding. We found that their life-history patterns are significantly different,L. bufoniusbeing larger, and having a higher reproductive output and lifespan, compared to the smaller and shorter-livingL. latinasus. Since none of the species exhibited sexual size dimorphism, and both acquired sexual maturity after the first year of life, we suggest that... |

| RESUMO As serpentes vindas da natureza e encaminhadas para centros de reabilitação ou de pesquisa têm uma idade incerta. Na natureza, esses animais, muitas vezes atingem um tamanho corpóreo menor do que os indivíduos cativos devido a uma menor frequência de alimentação. Assim, a idade de uma cobra recém-chegada da natureza é geralmente estimada com base em seu tamanho corpóreo, o qual é comparado com dados em cativeiro. A utilização dos meios de diagnóstico por imagem tem auxiliado a medicina na análise das serpentes em cativeiro, mediante avaliação da estrutura óssea, dos órgãos e de alterações. Este trabalho relata o uso de diagnóstico por imagem (radiografia e ultrassonografia) para identificar a presença de microchips e, consequentemente, estimar a... |

| The objective of this study was to establish a specific, sensitive and rapid PCR approach for the detection of Clostridium sp. at the genus level. Clostridium sp. in the duodenum, jejunum, ileum and cecum of broiler chickens were analyzed by 16S rRNA genes. The PCR detected the presence of Clostridium spp. in naturally contaminated intestinal samples. For the total gastrointestinal segments, 53.125, 65.625 and 59.375% samples were positive for naturally occurring Clostridium spp. at the ages 4, 14 and 30d, respectively. Analysis of the microbial contents indicated that Clostridium sp. was not consistently detected in all intestinal segments. These results can put in evidence the hypothesis that Clostridium spp. may be interfering in health and performance... |

| ABSTRACT A cross sectional study was conducted in two types of respiratory patients in hospital population. It was found that tuberculosis (T.B) was the most common type (29.66%) followed by the asthma (28.08%) and chronic obstructive pulmonary disease (COPD) (11.31%). Average age of diagnosis was 42.15 ± 0.65 years and average age at present 47.99 ± 0.70 years. Age group 51-60 years was more prone to this disease (21.13%). Most of the patients were married (80.06%). The highest representation of patients with respiratory diseases was observed in 1st birth order (30.36%) followed by 2nd (26.49%) and 3rd (18.45%), while the lowest was in 10th birth order (0.40%). Tuberculosis, asthma and COPD are the most prevalent types of respiratory diseases.... |

| The relationship between dental morphology, sex, body length and age of small cetaceans can be used to determine ontogeny, sexual dimorphism and geographical variation. The objective of this study was to determine the relationship between dental morphology, sex, body size and age. A total of 91 specimens of P. blainvillei and 80 specimens of S. fluviatilis accidentally captured in fisheries or stranded in northern Rio de Janeiro (21º37'-22º25'S), from September 1988 to November 1996 were analysed. The teeth root diameter in P. blainvillei was significantly different between the sex; the values for females were larger than males. In neither species aid we observed significant in variations dimension and number of teeth, thickness of dentine and cemental... |

| The role of diffusely adherent Escherichia coli (DAEC) in diarrheal disease has been controversial. However, DAEC strains were recently implicated in diarrheal disease in developing countries. To clarify whether DAEC are prevalent among sporadic cases of diarrheal illness in Osaka City, Japan, E. coli strains isolated between July 1997 and March 2000 during diarrheagenic E. coli (DEC) investigation were retrospectively examined. DAEC strains were recognized among 41 (4.4%) of 924 patients and formed the biggest subgroup of DEC. Previously, we reported that some DAEC strains caused epithelial cells to secrete as much IL-8 as enteroaggregative E. coli strains did. In this study, we attempted to evaluate epidemiologically whether the ability of DAEC to induce... |

| Leptospirosis is a re-emerging zoonosis with broad clinical spectrum and high mortality in severe forms. The aim of this study was to analyze clinical manifestations, laboratory findings, epidemiological data, and management in elderly patients with leptospirosis. Toward that end, we performed a descriptive analysis of 15 leptospirosis elderly cases (age 60-78 years) treated at the Clinic of Infectious Diseases of University Hospital - Pleven (1976-2012). Patients were serologically confirmed by microscopic agglutination test. Twelve cases (80%) presented with the severe form of leptospirosis. Co-morbidity (hypertonic diseases, chronic pulmonary diseases, chronic alcohol abuse, and diabetes) was registered in 13 cases. All cases had fever, oliguria,... |

| We analyzed the performance of 162 normal subjects, subdivided into groups according to age and schooling, in the oral comprehension tasks of the Boston Diagnostic Aphasia Examination translated and adapted to Brazilian Portuguese to obtain a profile of performance for the Brazilian population, as well as cut-off scores for each task, and to determine the best combination of tasks that distinguish normal from aphasic subjects, as a guide for clinicians. The normal subjects were compared to 69 aphasics. Age alone influenced the performance in the designation of actions (subjects above 70 years showing the worst performance); schooling alone influenced the comprehension of forms, colors and numbers (subjects with less than four years of education showing a... |

| The Vernier acuity of 50 normal untrained subjects (20 males and 30 females) was measured by the method of adjustment. Subjects were divided into five age ranges with 10 subjects in each age group: 5-10, 11-20, 21-30, 31-40, and 41-50 years. All subjects had normal visual acuity (20/20) and volunteered to participate in the experiment. Children were selected from a local school and adults recruited from the technical staff of the Department of Ophthalmology of the School of Medicine. Vernier acuity was higher in adults compared to children. Intraindividual variability was high and it was estimated that for most individuals of all age groups a range of 100 to 700 trials was necessary to obtain a mean with a precision of 10%. These results suggest that... |

| The present study was conducted to obtain reference values for brachial-ankle pulse wave velocity (baPWV) and to evaluate influencing factors of baPWV according to gender. Using automatic devices, baPWV was measured simultaneously in 2095 subjects. A total of 647 healthy subjects, none of whom presented atherosclerotic risk factors, were analyzed in the present study. Two different statistical methods were used to obtain reference values for baPWV according to subject gender and age. The association between baPWV value and gender, as well as other features, were analyzed. For male subjects, multiple stepwise analysis showed that age, systolic blood pressure (SBP), heart rate (HR), and plasma levels of triglycerides (TG) were independent predictors of... |

| The pharmacokinetics of scorpion venom and its toxins has been investigated in experimental models using adult animals, although, severe scorpion accidents are associated more frequently with children. We compared the effect of age on the pharmacokinetics of tityustoxin, one of the most active principles of Tityus serrulatus venom, in young male/female rats (21-22 days old, N = 5-8) and in adult male rats (150-160 days old, N = 5-8). Tityustoxin (6 µg) labeled with 99mTechnetium was administered subcutaneously to young and adult rats. The plasma concentration vs time data were subjected to non-compartmental pharmacokinetic analysis to obtain estimates of various pharmacokinetic parameters such as total body clearance (CL/F), distribution volume (Vd/F),... |

| Stem CO2 efflux is a highly variable component of the carbon budget of forest ecosystems. It reflects the balance between the CO2 respired by the living stem tissues, less the CO2 dissolved in the xylem sap moving upward in the transpiration stream, plus the CO2 transported from the roots and released at the stem. Although knowledge about such fluxes at different spatial and temporal scales has markedly increased, knowledge of the effects of silviculture treatments, such as fertilization, on stem CO2 effluxes are still limited, particularly when connecting above- and belowground processes. Using measurements obtained from twin plots (one control, one fertilized) installed in five-, 12- and 23-year-old stands of Pinus radiata, the objective of this study... |

| ABSTRACT: The analysis of the growth and development of various species has been done using the growth curves of the specific animal based on non-linear models. The objective of the current study was to evaluate the fit of the Brody, Gompertz, Logistic and von Bertalanffy models to the cross-sectional data of the live weight of the MangalargaMarchador horses to identify the best model and make accurate predictions regarding the growth and maturity in the males and females of this breed. The study involved recording the weight of 214 horses, of which 94 were males and 120 were non-pregnant females, between 6 and 153 months of age. The parameters of the model were estimated by employing the method of least squares, using the iteratively regularized... |

| ABSTRACT: Cystic echinococcosis is a parasitic infection of worldwide distribution, which, despite causing significant loss of health and money, is still a neglected disease. The present study was performed to determine the prevalence of bovine hydatid disease at Research Centre for the Conservation of Sahiwal Cattle, Jahangirabad, Khanewal, Pakistan. Five hundred bovine serum samples were tested for the detection of bovine Echinococcus antibodies (IgG), using the ELISA kits. Antibodies of bovine Echinococcus were detected in 24.2% cattle. Female cattle showed higher disease prevalence (33.2%) compared to (6.02%) in male cattle. There was positive association between sex of cattle and prevalence (P<0.05). Positive correlation between disease prevalence... |
