Effect of Potassium Permanganate, Ultraviolet Radiation and Titanium Oxide as Ethylene Scavengers on Preservation of Postharvest Quality and Sensory Attributes of Broccoli Stored with Tomatoes.

This study introduces an effective solution to enhance the postharvest preservation of broccoli, a vegetable highly sensitive to ethylene, a hormone produced by climacteric fruits such as tomatoes. The proposed method involves a triple combination of ethylene elimination techniques: potassium permanganate (KMnO4) filters combined with ultraviolet radiation (UV-C) and titanium oxide (TiO2), along with a continuous airflow to facilitate contact between ethylene and these oxidizing agents. The effectiveness of this approach was evaluated using various analytical techniques, including measurements of weight, soluble solids content, total acidity, maturity index, color, chlorophyll, total phenolic compounds, and sensory analysis conducted by experts. The results demonstrated a significant improvement in the physicochemical quality of postharvest broccoli when treated with the complete system. Notably, broccoli subjected to this innovative method exhibited enhanced organoleptic quality, with heightened flavors and aromas associated with fresh green produce. The implementation of this novel technique holds great potential for the food industry as it reduces postharvest losses, extends the shelf life of broccoli, and ultimately enhances product quality while minimizing waste. The successful development and implementation of this new technique can significantly improve the sustainability of the food industry while ensuring the provision of high-quality food to consumers.

Empleo de metronidazol en un niño con tétanos neonatal / The treatment of neonatal tetanus with metronidazole

Se Presenta el caso de un recién nacido con diagnóstico de tétanos neonatal, el cual se calificó en la escala de Patel como grado V y periodo de Cole III. Fue manejado inicialmente con apoyo ventilatorio, penicilina sódica cristalina, amikacina, antitoxina tetánica, relajantes musculares y sedantes; sin observar respuesta adecuada. Doce días después se decide el manejo con metronidazol intravenoso con muy buena respuesta. Se incluye que el manejo con metronidazol es una alternativa que debe ser estudiada en el futuro
