The objective of this field trial was to evaluate effects of a single administration of 2.2 mg/kg of body weight (BW) of flunixin meglumine (FM) in addition to a systemic antibiotic treatment in cows with acute puerperal metritis (APM). Outcome variables tested were proportion of cows with a fever, prevalence of chronic endometritis 18 to 22 and 32 to 35 d in milk (DIM), and reproductive performance measures in the current lactation. In addition, serum concentrations of haptoglobin and fibrinogen were analyzed. Daily milk yield within 6 d after the first treatment was recorded. Cows were examined 4 to 5 DIM by rectal palpation and vaginoscopy, and rectal temperature was measured. Fetid vulvar discharge and a body temperature > or = 39.5 degrees C were signs of APM. Cows with APM were treated in the reference group with 1.0 mg/kg of BW of ceftiofur on 3 to 5 consecutive days (CEF, n = 119). In the study group, cows received the same antibiotic treatment as in CEF and 2.2 mg/kg of BW of FM on treatment d 1 (CEF + FM, n = 119). Blood samples were collected 4, 6, and 10 DIM and analyzed for concentrations of haptoglobin and fibrinogen. A group of cows without APM remained untreated and served as controls (n = 9). There were no significant differences between CEF and CEF + FM in the proportion of cows with fever 1 d after the first treatment (33.6 vs. 46.2%), milk yield per milking 10 DIM (7.5 +/- 0.3 vs. 7.6 +/- 0.3 kg in primiparous, 9.6 +/- 0.4 vs. 10.6 +/- 0.4 kg in multiparous cows), prevalence of chronic endometritis 32 to 35 DIM (64.3 vs. 52.2%), and in reproductive performance (31.5 vs. 34.3% conception to first AI, 58.0 vs. 54.6% pregnancy rate, 107.8 +/- 36.9 vs. 101.6 +/- 41.4 d open). Compared with the control, CEF and CEF + FM had significantly greater concentrations of haptoglobin (1.1 +/- 0.28 vs. 1.9 +/- 0.06 and 1.8 +/- 0.07 mg/mL at 4 DIM; 0.3 +/- 0.15 vs. 1.1 +/- 0.06 and 1.2 +/- 0.07 mg/mL at 10 DIM) and fibrinogen (2.2 +/- 0.17 vs. 3.9 +/- 0.14 and 3.7 +/- 0.13 g/L at 4 DIM; 1.9 +/- 0.1 vs. 2.6 +/- 0.1 and 3.0 +/- 0.13 g/L, respectively, at 10 DIM) on all test days. The additional treatment with FM had no effect on these acute phase proteins. In conclusion, the single administration of 2.2 mg/kg of BW of FM in addition to a systemic antibiotic treatment of cows having APM did not result in beneficial effects on clinical cure, milk yield within 6 d after the first treatment, or reproductive performance.

By the year 2050, the world’s elderly population may increase exponentially, raising the rate of disease characteristic of this group, such as prostate cancer (PCa) and benign prostatic hyperplasia (BPH). Prostate disorders have a multifactorial etiology, especially age and genetic factors. Currently, PCa is the second most frequent neoplasm in the male population worldwide. The fibromodulin gene encodes a small leucine-rich proteoglycan (SLRP) which acts in the collagen fibrillogenesis pathway, cell adhesion, and modulation of TGF-β signaling pathways, which has been recently associated with PCa. The present study sequenced the coding region of the FMOD in a sample of 44 PCa, 90 BPH, and 82 controls from a Brazilian population, and the results identified 6 variants: 2 missenses (p.(Tyr42Ser) and p.(Pro24Ala)); 3 synonymous (p.(His253=), p.(Asn353=), and p.(Glu79=)); and 1 intronic (c.980-114A>G). Of these, p.(Tyr42Ser), p.(Pro24Ala), and p.(Asn353=) are rare variants, and p.(Tyr42Ser) was predicted as potential pathogenic by the algorithms used here, in addition to not being observed in controls, suggesting that may be a potential biomarker for development of PCa and BPH. In conclusion, we identified for the first time, in Brazilian individuals with PCa and BPH, a potentially pathogenic variant in the analysis of FMOD gene. Further studies are needed to investigate the deleterious effect of this variant on the structure and/or function of the FMOD protein.

Resumo. Na maioria das espécies de aves não é possível realizar a identificação do gênero pelas características fenotípicas externas já que os órgãos reprodutivos são internos. Sendo assim, como é fundamental para os criadores realizar esta diferenciação sexual não apenas pela reprodução mas também pelo fato que em algumas espécies apenas os machos manifestam certas características como o canto, é extremamente importante realizar a sexagem de aves por meio da análise do DNA, que além de conferir 99,9% de confiabilidade ao resultado, traz outras vantagens em relação a outras técnicas, como a diminuição do estresse e do risco de danos à ave e também o fato de ser aplicado a partir de qualquer idade (ideal para os filhotes). O objetivo deste trabalho foi realizar a sexagem de 13 aves da espécie de Amazona aestiva (Papagaio-Verdadeiro) por meio da técnica de PCR (Reação em Cadeia de Polimerase). Já que nas aves o sexo heterogamético é o das fêmeas, duas bandas foram observadas para este sexo e apenas uma foi observada para o masculino, sendo identificados 5 machos e 3 fêmeas. A partir dos resultados obtidos foi possível concluir que a técnica de PCR permitiu identificar o sexo dos animais de forma eficaz e pouco invasiva representando uma importante ferramenta para o direcionamento de acasalamentos e conservação da espécie de aves silvestres.
