Introduction. Fetal obstructive uropathy can be treated early in pregnancy by intrauterine vesicoamniotic shunting, immediately after diagnosis by ultrasound, in specific cases with a favorable prognosis in renal function using fetal urine beta-2 microglobulin. Objective: To determine the changes of beta-2 microglobulin in consecutive samples of fetal urine in 48 – 72 hour-intervals in fetuses with obstructive uropathy at 16 weeks of gestation. Methods: We designed a descriptive and longitudinal study, including 15 pregnant women whose fetuses were diagnosed with obstructive uropathy without chromosomal abnormalities, performing vesicocentesis for urinary biometry. Results: Beta-2 microglobulin values were higher than 4 mg/dL in the first vesicocentesis of all 15 cases and decreased to less than 4 mg/dL in 7 cases (46.6%) after the second vesicocentesis. In all cases when beta-2 microg...

Twin-to-twin transfusion syndrome (TTTS) is thought to result from an unbalanced exchange of blood through inter-twin vascular anastomoses. Laser photocoagulation of communicating vessels has been used to prevent the development of the syndrome. Some authors have proposed that vessels crossing the membrane are “suspicious” to participate in the development of the syndrome and the laser photocoagulation of these vessels would reverse the syndrome. We present two cases of TTTS where the communicating vessels did not cross the dividing membrane, which were successfully treated with laser.

La investigación tuvo como objetivo determinar cómo las billeteras digitales inciden en la evasión tributaria en las personas naturales con negocios del distrito de Ate Vitarte en 2023. La metodología fue de nivel correlacional, con enfoque cuantitativo y método descriptivo-explicativo. Se utilizó una muestra de 40 colaboradores, aplicando encuestas mediante cuestionarios. Los resultados mostraron que una gran mayoría de los encuestados percibe la innovación de la billetera digital como un valor agregado para los comercios electrónicos, con un 95% de acuerdo (37.5% de acuerdo y 57.5% totalmente de acuerdo). Además, el 90% reconoce la importancia de comprender la evasión tributaria. Los datos indican que los sistemas de pago electrónicos inciden significativamente en la evasión tributaria de los comerciantes. Se recomienda afianzar alianzas con entidades bancarias y la Admini...

Esta investigación tuvo como objetivo evaluar las características físicas (humedad, cenizas, materia volátil y carbono fijo) en las biomasas de borra de café, tallo y raquis de maíz, así como el potencial energético (poder calorífico) para su posible uso en la elaboración de un biocombustible sólido; para esto se obtuvo la borra de café en la Compañía “EL CAFÉ C.A” del cantón Montecristi-Manabí, mientras el tallo y raquis de maíz en el cantón Pichincha-Manabí; los análisis proximales fueron realizados en el Laboratorio de Bromatología de la Escuela Superior Politécnica Agropecuaria de Manabí Manuel Félix López. Los resultados demostraron que la biomasa de borra de café presentó un mayor contenido de humedad, carbono fijo y poder calorifico con valores de 12.8, 3.16 y 14.3% respectivamente, mientras que el tallo se observó una mayor concentración de ceniz...
