Ultrasound and Microwave-Assisted Synthesis of Hexagonally Ordered Ce-Promoted Mesoporous Silica as Ni Supports for Ethanol Steam Reforming.

Solvothermal synthesis of mesoporous materials based on amphiphilic molecules as structure-directing agents can be enhanced using non-conventional technologies for stirring and thermal activation. Here, we disclose a green synthesis approach for the preparation of cerium-modified hexagonally ordered silica sieves. Ultrasound micromixing enabled us to obtain well-dispersed Ce in the self-assembled silica network and yielded ordered materials with high cerium content (Ce/Si molar ratio = 0.

[Incidencia de la operación cesárea según la clasificación de Robson en el Servicio de Ginecología y Obstetricia del Hospital Gral. Dr. Fernando Quiroz Gutiérrez del Instituto de Seguridad Social al Servicio de los Trabajadores del Estado].

IntroducciÓn: El número de cesáreas en todo el mundo se ha incrementado de forma importante y nuestro país no es la excepción. En algunos lugares se supera el 60% de cesáreas en relación al parto vaginal. No existe una clasificación adecuada para el análisis de este incremento.

Preeclampsia is associated with ACE I/D polymorphism, obesity and oxidative damage in Mexican women.

Objective: This study sought to determine whether the angiotensin-converting enzyme insertion/deletion (ACE I/D) polymorphism, obesity and oxidative damage are risk factors for the development of preeclampsia in Mexican women.

Study Design: A total of 66 women with preeclampsia (PE) and 37 women with normal pregnancies (NP) were included in the study. DNA was extracted from whole blood, and the ACE I/D polymorphism was evaluated by polymerase chain reaction.

[Profile dipper/non-dipper in patient with severe preeclampsia, eclampsia and HELLP syndrome during pregnancy and puerperium].

Background: Blood pressure (BP) has a circadian rhythm, decreases at night and increases in the morning (dipper), have been observed in patients with impaired in this profile, increased at night and lower in the morning (no dipper) have increased cardiovascular risk. Preeclampsia-eclampsia complicates about 7% of pregnancies, preeclampsia is known to reverse the normal circadian cycle of the BP.

Objective: To determine the profile dipper/non-dipper in patients with severe preeclampsia, eclampsia and HELLP syndrome patients in Intensive Care and Obstetrics Hospital Juárez of México.

[Primary cervical cancer screening].

Cervico-uterine cancer screening with cytology decrease incidence by more than 50%. The cause of this cancer is the human papilloma virus high risk, and requires a sensitive test to provide sufficient sensitivity and specificity for early detection and greater interval period when the results are negative. The test of the human papilloma virus high risk, is effective and safe because of its excellent sensitivity, negative predictive value and optimal reproducibility, especially when combined with liquid-based cytology or biomarkers with viral load, with higher sensitivity and specificity, by reducing false positives for the detection of cervical intraepithelial neoplasia grade 2 or greater injury, with excellent clinical benefits to cervical cancer screening and related infection of human papilloma virus diseases, is currently the best test for early detection infection of human papillomavirus and the risk of carcinogenesis.
