Porcine reproductive and respiratory syndrome (PRRS) is caused by a genetically diverse RNA virus and is an economically significant disease in the swine industry. In this study, a total of 8,126 serum samples were obtained from 275 technified and semi-technified farms belonging to 30 of the 32 states of Mexico and representative of the eight regions of the country. Anti-PRRSv antibodies against the PRRS vaccine and an isolated wild Mexican virus were tested by ELISA.

- The study assessed the effects of weathered and non-weathered oil on red drum larvae, focusing on survival, physical deformities, and heart function.
- The lethal concentration (LC50) values for red drum larvae were found to be between 14.6 and 21.3 μg/L ΣPAH, with no significant differences based on exposure timing or oil weathering.
- Results showed that exposure led to major reductions in cardiac output, particularly affecting stroke volume rather than heart rate, highlighting a concerning sensitivity in cardiac function that aligns with findings in similar pelagic species.
Article Synopsis
- Maternal metabolic changes during pregnancy can significantly affect fetal metabolism, increasing the risk of chronic diseases for the child later in life.
- The study analyzed glucose, lipid profiles, and adipokine levels in healthy pregnant women who delivered via C-section, revealing that fetal blood has higher adiponectin and resistin, but lower leptin levels compared to mothers.
- Results indicated an inverse relationship between maternal resistin and fetal LDL-cholesterol, alongside increased maternal leptin and fetal LDL-C in women with excessive weight gain, suggesting that maternal weight influences fetal metabolic regulation.
