ABSTRACT

Endoplasmic reticulum (ER) stress plays a key role in the pathogenesis of several organ damages. Studies show that excessive ER stress (ERS) can destroy cellular homeostasis, causing cell damage and physiological dysfunction in various organs. In recent years, Sirtuin1 (SIRT1) has become a research hotspot on ERS. Increasing evidence suggests that SIRT1 plays a positive role in various ERS-induced organ damage via multiple mechanisms, including inhibiting cellular apoptosis and promoting autophagy. SIRT1 can also alleviate liver, heart, lung, kidney, and intestinal damage by inhibiting ERS. We discuss the possible mechanism of SIRT1, explore potential therapeutic targets of diseases, and provide a theoretical basis for treating ERS-related diseases.

ABSTRACT

The biological and bacteriological action of calcium hydroxide confer to its current success as an intracanal dressing. For this reason the mechanism of action of calcium and hydroxyl ions on tissue and bacteria deserves further study. The objective of the present paper is to analyze and discuss the mechanism of action of calcium and hydroxyl ions on anaerobic bacteria, starting from the isolated study of the influence of pH on these bacteria, as well as the mechanism of action of calcium hydroxide on tissue

ABSTRACT

Los traumatismos se diagnostican ahora con un alto grado de exactitud radiológica con el uso rutinario de la tomografía axial computarizada, en este estudio se visualiza con mas claridad los tejidos blandos como los tejidos óseos. Un conjunto variado de métodos invasores de diagnóstico y de monitoreo continuo de todos los sistemas orgánicos permite que el paciente con traumatismos facilaes puede ser operado con seguridad en los momentos iniciales. la aplicación de las técnicas craneofaciales de exposición ha aumentado la posibilidad de restaurar el aspecto facial que el paciente presentaba antes del trauma. El tratamiento con miniplacas, alambres han mejorado los resultados funcionales y estéticos del tratamiento de las fracturas de cara. Mantener un orden establecido es de gran importancia para el tratamiento óptimo de los traumatismos de lacara. es axiomático que los traumas de tejidos blandos y de los huesos de la zona facial sean tratados tan pronto como el estado general del paciente lo permita, por loq ue un tratamiento temprano disminuye la posibilidad de desfiguración facial permanente y de limitaciones funcionales graves, aunque los traumatismos blandos y óseos rara vez sean emergencias quirúrgicas.
