Effect of season, late embryonic mortality and progesterone production on pregnancy rates in pluriparous buffaloes (Bubalus bubalis) after artificial insemination with sexed semen

The use of sexed semen technology in buffaloes is nowadays becoming more and more accepted by farmers, to overcome the burden of unwanted male calves with related costs and to more efficiently improve production and genetic gain. The aim of this study was to verify the coupling of some variables on the efficiency of pregnancy outcome after deposition of sexed semen through AI. Pluriparous buffaloes from two different farms (N = 152) were screened, selected, and subjected to Ovsynch protocol for AI using nonsexed and sexed semen from four tested bulls. AI was performed in two distinct periods of the year: September to October and January to February. Neither farms nor bulls had a significant effect on pregnancy rates pooled from the two periods. The process for sexing sperm cells did not affect pregnancy rates at 28 days after AI, for nonsexed and sexed semen, respectively 44/73 (60.2%) and 50/79 (63.2%), P = 0.70, and at 45 days after AI, for nonsexed and sexed semen, respectively 33/73 (45.2%) and 33/79 (49.3%), P = 0.60. Pregnancy rate at 28 days after AI during the transitional period of January to February was higher when compared with September to October, respectively 47/67 (70.1%) versus 47/85 (55.2%), P = 0.06. When the same pregnant animals were checked at Day 45 after AI, the difference disappeared between the two periods, because of a higher embryonic mortality, respectively 32/67 (47.7%) versus 40/85 (47.0%), P = 0.93. Hematic progesterone concentration at Day 10 after AI did not distinguish animals pregnant at Day 28 that would or would not maintain pregnancy until Day 45 (P = 0.21). On the contrary, when blood samples were taken at Day 20 after AI, the difference in progesterone concentration between pregnant animals that would maintain their pregnancy until Day 45 was significant for both pooled (P = 0.00) and nonsexed (P = 0.00) and sexed semen (P = 0.09). A similar trend was reported when blood samples were taken at Day 25, being highly significant for pooled, nonsexed, and sexed semen (P = 0.00). Hematic progesterone concentration between the two periods of the year was highly significant for pregnant animals at 28 days from AI when blood samples were taken at Day 20 after AI for pooled, nonsexed, and sexed semen, respectively P = 0.00, 0.00, and 0.06, and for pregnant animals at Day 45 for pooled, nonsexed, and sexed semen, respectively P = 0.00, 0.00, and 0.01. From these results, it can be stated that hematic progesterone concentration measurement since Day 20 after AI can be predictive of possible pregnancy maintenance until Day 45. Furthermore, the transitional period of January to February, although characterized by a higher pregnancy outcome when compared with September to October, suffers from a higher late embryonic mortality as evidenced by a significant different hematic progesterone concentration between the two periods at Day 20 after AI

Análise do efeito do contraste iodado sobre marcadores renais de pacientes submetidos à angiografia coronariana

Objetivo: O objetivo deste trabalho foi avaliar os efeitos da administração de contraste iodado sobre marcadores renais clássicos em pacientes submetidos à angiografia coronariana. Métodos: Este foi um estudo do tipo coorte e contou com 17 pacientes do sexo masculino, com média de idade de 65 anos, que foram submetidos à angiografia coronariana. Resultados: Em relação aos dados antropométricos, foi evidenciada a prevalência de sobrepeso em 64% dos pacientes. Quanto às doenças pré-existentes, destacamos que 82% da amostra era de indivíduos hipertensos. Além disso, 59% dos pacientes eram tabagistas. Sobre os medicamentos utilizados, entre os pacientes hipertensos, 53% faziam uso de losartana sódica, 22% de beta-bloqueadores e 11% de diuréticos. A avaliação do hemograma evidenciou que 72 horas após o procedimento houve redução significativa de hemoglobina, hematócrito, leucócitos e plaquetas. Com relação à creatinina, 41,2% dos pacientes apresentaram risco de comprometimento renal. Já, quando utilizamos os níveis de ureia plasmática, observamos que 29,5% dos pacientes apresentaram risco de comprometimento renal. Por fim, também avaliamos a TFG que mostrou risco de lesão renal em 23% dos pacientes. Considerações Finais: No presente estudo, observamos que que o uso de contraste iodado em pacientes idosos submetidos à angiografia coronariana é um risco que deve ser considerado para o desenvolvimento de nefropatia induzida por contraste e que o uso do protocolo de hidratação venoso após o procedimento é importante para evitar lesão renal

Interpreting and technology

Unlike other professions, the impact of information and communication technology on interpreting has been moderate so far. However, recent advances in the areas of remote, computer-assisted, and, most recently, machine interpreting, are gaining the interest of both researchers and practitioners. This volume aims at exploring key issues, approaches and challenges to the interplay of interpreting and technology, an area that is still underrepresented in the field of Interpreting Studies. The contributions to this volume cover topics in the area of computer-assisted and remote interpreting, both in the conference as well as in the court setting, and report on experimental studies
