Epidemiological Survey of Equine Pythiosis in the Brazilian Pantanal and Nearby Areas: Results of 76 Cases

A clinical epidemiological study was conducted among 34 rural properties located within the Brazilian Pantanal region and nearby areas between 2007 and 2010. The diagnosis of equine pythiosis was based on antibody detection (by enzyme-linked immunosorbent assay), polymerase chain reaction, histopathological analysis, and cultures positive for Pythium insidiosum. The majority of the affected animals (85%) were in the Pantanal biome, which had a higher disease prevalence (0.9%-66.7%) than that of the Cerrado (2.7%-33.3%). The disease was more prevalent in the rainy season (January-March), with an abrupt fall in the number of cases during the drought period (April-September; correlation of R 2 = 0.77; P < .01). Generally, the average prevalence of equine pythiosis in both regions was 5%, with mortality and lethality rates of 1.3% and 23.1%, respectively, in the Pantanal and 2.3% and 45.5%, respectively, in the Cerrado. However, the treatment with immunotherapy may have underestimated these numbers, especially in the Pantanal. Animals older than 1 year were 8.09 times more affected by the disease than younger animals in the same environment (P < .05). A correlation between the anatomical area of the lesion and the type of skin color was also observed. Approximately 73% of the lesions were found in dark-pigmented areas, and animals with a dark coat color were affected more frequently. These findings highlight the importance of hematophagous insects in the epidemiology of pythiosis because these areas are preferred for blood feeding. © 2013 Elsevier Inc. All rights reserved.

Controle de qualidade e levantamento radiométrico em aparelho de Raios-X médico convencional

Along with the advance of technology, in terms of the expansion of medical exams that uses the ionizing radiation for diagnosis, there is also the concern about quality control for maintaining quality in radiographic imaging and for delivering low dose to the patient. Based on the Federal Order 453 of the Secretariat of Health Surveillance, which takes account of the practical and justification of individual medical exposures, the optimization of radiological protection, limitation of individual dose, and the prevention of accidents, were done through this paper radiodiagnostic tests on medical equipment in order to accept it or not, according to SVS-453. Along with the help and support of P&R Consulting and Medical Physics Marilia, SP, were made Quality Control and Radiometric Control in equipment from various cities across the state of São Paulo. The equipment discussed in this work is classified as conventional X-ray. According to the Federal Order SVS-453, the quality control in the program of quality assurance should include the following minimum set of constancy tests, with following minimum frequency: biennial tests for representative values of dose given to the patients of radiography and CT performed in the service; annual tests for accuracy of the indicator tube voltage (kVp), accuracy of exposure time, half-value layer, aligning the central axis of the beam of x-ray tube, performance (mGy / mA.min.m²), linearity of the rate of kerma on air with the mAs, reproducibility of the kerma on air rates, reproducibility of the automatic exposure, focal spot size, integrity of accessories and clothing for individual protection; semiannually for collimation system accuracy; weekly for temperature processing system and sensitometry processing system. For the room Radiometric Survey it was done a sketch...(Complete abstract click electronic access below)

Quantum chemical topological analysis of hydrogen bonding in HX…HX and CH3X…HX dimers (X = Br, Cl, F)

We present a systematic investigation of the nature and strength of the hydrogen bonding in HX···HX and CH3X…HX (X = Br, Cl and F) dimers using ab initio MP2/aug-cc-pVTZ calculations in the framework of the quantum theory of atoms in molecules (QTAIM) and electron localisation functions (ELFs) methods. The electron density of the complexes has been characterised, and the hydrogen bonding energy, as well as the QTAIM and ELF parameters, is consistent, providing deep insight into the origin of the hydrogen bonding in these complexes. It was found that in both linear and angular HX…HX and CH3X…HX dimers, F atoms form stronger HB than Br and Cl, but they need short (∼2 Å) X…HX contacts.

Diagnóstico radiográfico diferencial das reabsorções radiculares internas e externas entre especialistas em endodontia e clínicos gerais

Objectives: The objective of this study was to evaluate the ability of endodontists and general practioners to perform the differential radiographic diagnosis between internal and external root resorptions, using digitized periapical radiographs. Methods: Thirty periapical radiographic images of external and internal resorption were selected. The evaluators were comprised of 15 endodontists and 29 general practitioners who answered a questionnaire with the following question: “What type of resorption in the following radiographics do you diagnose?” (1) Inflammatory external root resorption. (2) Internal root resorption. Statistical analysis was performed based on the Mann-Whitney test, with significance level of 5%. Results: There was no statistically significant difference in the percentage of correct answers from specialists in endodontics and general practitioners. Conclusions: Both groups demonstrated satisfactory skill in the radiographic interpretation of internal and external resorption and there was a higher percentage of correct diagnosis of internal resorption than the external.

Algas verdes coloniais em riachos de Unidades de Conservação do Sul do Brasil: taxonomia e aspectos ecológicos

Species of colonial green algae from 10 Conservation Units from the Southern Brazil were surveyed. The samplings were carried out in 105 stream reaches, consisting of 10 m length transects. In addition to biological data, some environmental variables were measured: depth, current velocity, water temperature, turbidity, specific conductance, pH, dissolved oxygen and nutrients (total nitrogen and orthophosphate). Three species of colonial green algae [Bohlin Ecballocystis pulvinata var. pulvinata, Tetraspora gelatinosa (Vaucher) Desvaux and T. lubrica (Roth) C Agard] were recorded and these species were described and illustrated. Based on the environmental data, it was observed some patterns of ecological distribution, including the occurrence of E. pulvinata var. pulvinata in environments with higher water temperature and current velocity values, while Tetraspora species typically occurred in environments with lower total nitrogen, orthophosphate and specific conductance values.

Suplementação com gordura protegida para vacas de corte desmamadas precocemente mantidas em pastagem natural

The objective of this work was to evaluate the productive and reproductive performance of beef cows, as well as the performance of their calves according to the following dietary treatments: PRE: supplemented with protected fat (PF) during 45 days prepartum; PREPOS: supplemented with PF during 45 days prepartum and 63 days postpartum; POS: supplemented with PF during 63 days postpartum; PN: without supplementation. The productive performance of cows was not influenced by feed management (P>0.05), except for body condition score (BCS), which was lower for PRE and PREPOS cows at the end of mating season, with the latter cows having similar BCS POS and PN. The calving interval (CI) was shorter for cows supplemented in PREPOS - 376 days -, and did not differ in cows maintained in PN - 383 days. Supplemented PREPOS cows weaned 4.4% more pounds of calf per 100kg of cow at calving - 22.6kg - than the PRE and POS cows - 21.6kg and 21.6kg, respectively - and 8,4% more pounds of calf per 100 of cow at calving than the cows maintained in native pasture - 20.7kg. The fat protected supplementation during pre and/or postpartum periods did not affect the performance of cows and calves.
