La criopreservación de semen produce un alto grado de alteraciones en los espermatozoides que generan una consecuente pérdida de fertilidad y una menor tasa de preñez si se le compara con el semen fresco. Debido a esto, el presente estudio tuvo como objetivo evaluar el efecto del método de congelación y el periodo de incubación sobre la calidad del semen equino luego de la descongelación. Para ello, se colectó semen de tres equinos mediante vagina artificial. El semen fue sometido a dos métodos de congelación: vapores de nitrógeno y congelador programable. Una vez descongelado, el semen se mantuvo a 37 °C en baño de agua e incubadora, y se realizaron evaluaciones de calidad seminal a las 0, 1 y 2.5 h. Se determinó que el empleo de vapores de nitrógeno resulta ser el más adecuado para criopreservar semen equino y que el mantenimiento del semen descongelado en incubadora r...

Noncommunicable Chronic Diseases (CNCD) are long-term conditions and their evolution is slow. Currently the number of cases is on the rise and represent the leading cause of death worldwide. The treatments are usually complex and if the population does not begin to take responsibility, taking into account the healthy habits, the consequences will be greater for the health systems. For this reason, a program based on the Primary Health Care approach was prepared, submitted to expert analysis and a pretest-posttest design research was established in the municipalities located in the Toluca Valley, in the center of the country with 188 patients with CNCD.

This study analyzed the impact of code-generating artificial intelligences (AI), such as GitHub Copilot, on programmers' work. It aimed to determine how these tools affect productivity and code quality, differentiating their effects based on developers' experience levels. A systematic literature review and tool analysis were conducted, using the PRISMA methodology to assess experimental studies and usage reports. Results revealed that code-generating AIs improved productivity by up to 55.8% for experienced programmers, while less experienced developers exhibited increased reliance and confidence in generated code, leading to security risks. Additionally, benefits included reduced development times and democratized access to software, though ethical and technical risks related to overdependence and loss of fundamental skills were noted. These findings underscore the need for strategies th...
