Bone Disorders01:29

Bone Disorders

5.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Unsoundness of Aggregate due to Volume Change01:26

Unsoundness of Aggregate due to Volume Change

353
Unsoundness in aggregates due to volume changes is primarily caused by the physical alterations aggregates undergo, such as freezing and thawing, thermal changes, and wetting and drying. Unsound aggregates, when subjected to these changes, result in volume change upon disintegration. This, in turn, contributes to the deterioration of concrete, including scaling, pop-outs, and cracking. Particular types of aggregates, such as porous flints, cherts, and those containing clay minerals, are...

The Effect of Aging on Tissues

3.2K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Mortar Joint Deterioration in Masonry01:13

Mortar Joint Deterioration in Masonry

330
Mortar joint deterioration is a significant concern in masonry structures, with water accumulation in the joints leading to damage from freeze-thaw cycles. The repeated expansion of water during freezing and its melting during thawing develop and propagate cracks in the masonry joints. Eventually, this leads to the spalling of mortar from the joints, loosening masonry units and weakening the structure. The deteriorated mortar joints are also vulnerable to moisture intrusion into the walls.

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

5.9K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Resumen

La función del otolito disminuye con la edad y el sexo, pero factores sistémicos como la tiroxina libre y el colesterol HDL también impactan la salud del otolito. Comprender estos factores es clave para abordar los mareos y el vértigo.

Área de la Ciencia:

  • Otorrinolaringología; Neurociencia; Gerontología

Sus antecedentes:

  • La degeneración del otolito está relacionada con el envejecimiento, pero otros factores que contribuyen siguen sin estar claros. Los mareos y el vértigo son síntomas comunes a menudo asociados con una función del otolito alterada. La identificación de los factores de riesgo para la disfunción del otolito es crucial para el manejo eficaz del paciente.

Objetivo del estudio:

  • Identificar factores de riesgo sistémicos asociados con la función del otolito en pacientes que experimentan mareos y vértigo. Investigar la relación entre la función del otolito y varios parámetros demográficos y bioquímicos.

Principales métodos:

  • Estudio transversal de 624 pacientes con trastornos vestibulares. La función del otolito se evaluó mediante las amplitudes sumadas de los potenciales miogénicos vestibulares cervicales y oculares (SA-cVEMPs y SA-oVEMPs). Se utilizaron modelos lineales generalizados para analizar las asociaciones entre la función del otolito y los factores de riesgo.

Principales resultados:

  • La SA-cVEMP se asoció negativamente con la edad, el sexo femenino y la tiroxina libre, y positivamente con el colesterol HDL. La SA-oVEMP mostró una asociación negativa con la edad y positiva con el sexo femenino. La edad y el sexo fueron predictores significativos tanto para la SA-cVEMP como para la SA-oVEMP.

Conclusiones:

  • Los factores sistémicos, incluida la tiroxina libre y el colesterol HDL, influyen significativamente en la función del otolito más allá de la edad y el sexo. Estos hallazgos sugieren que los cambios microvasculares y estructurales contribuyen a la degeneración del otolito. La comprensión de estos impactos sistémicos ofrece nuevas perspectivas sobre los trastornos vestibulares y la salud del otolito.
