In situ Compressive Loading and Correlative Noninvasive Imaging of the Bone-periodontal Ligament-tooth Fibrous Joint
Published on: March 7, 2014
Resumen
Los nuevos métodos de resucitación cardiopulmonar (RCP) se centran en aumentar la presión intratorácica o la fuerza de compresión. Si estas técnicas avanzadas de RCP mejoran la supervivencia del paciente en humanos requiere más investigación.
Área de la Ciencia:
- Cardiología Cardiología.
- Medicina de emergencia Medicina de emergencia.
- Fisiología Fisiología Fisiología.
Sus antecedentes:
- La resucitación cardiopulmonar (RCP) tiene como objetivo mantener el flujo sanguíneo durante el paro cardíaco.
- Los métodos establecidos de RCP están siendo reevaluados con nuevas investigaciones sobre los mecanismos subyacentes.
Objetivo del estudio:
- Revisar nuevos enfoques para la entrega de RCP.
- Discutir los mecanismos y las posibles optimizaciones de la RCP.
Principales métodos:
- Revisión de estudios recientes sobre las técnicas de RCP.
- Análisis de los mecanismos propuestos, incluida la "bomba torácica" y la compresión cardíaca directa.
- Evaluación de modificaciones como ventilación y compresión simultáneas, compresión abdominal y velocidades/fuerzas de compresión alteradas.
Principales resultados:
- La evidencia sugiere que el flujo hacia adelante durante la RCP puede ser generado por una presión intratorácica elevada (mecanismo de bomba torácica).
- Los estudios indican posibles mejoras en el flujo con maniobras como la ventilación simultánea, la compresión abdominal y el aumento de la fuerza/tasa de compresión.
- También se están explorando secuencias alternativas de ventilación y compresión.
Conclusiones:
- La eficacia clínica de las nuevas técnicas de RCP en humanos sigue sin estar probada.
- La adopción generalizada de cualquier nuevo método de CPR dependerá de su simplicidad, aplicabilidad sin accesorios y facilidad de capacitación pública.

Complementation Tests
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

Base Excision Repair
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Loose Connective Tissue
Loose connective tissue is found between many organs. Its main function is to absorb shock and bind tissues together. It also allows water, salts, and various nutrients to diffuse into cells that are embedded in it or present in adjacent tissues.
Adipose Tissue
Adipose tissue consists primarily of fat storage cells called adipocytes and little extracellular matrix. A large number of capillaries present within adipose tissue allow rapid mobilization of lipid molecules. White adipose tissue is...

Method of Joints: Problem Solving I
The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint. Consider a truss structure with two forces of 20 N and 10 N acting at joints C and D, respectively. The method of joints can be used to determine the forces FCB, FDC,...
Posttensioned Masonry Walls
Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...
