Resumen
La depresión exacerba la hipoensitividad de la materia blanca (WMH) y el deterioro cognitivo en los adultos mayores negros e hispanos, pero no en los adultos mayores blancos. La raza y la depresión interactúan para afectar la carga de enfermedades cerebrovasculares y la función cognitiva.
Área de la Ciencia:
- La neurociencia es la neurociencia.
- Gerontología Gerontología.
- Salud Pública La salud pública.
Sus antecedentes:
- Las hipotensidades de la materia blanca (WMH) están vinculadas al deterioro cognitivo y la demencia.
- La influencia de la raza, el origen étnico y la depresión en WMHs no se entiende bien.
Objetivo del estudio:
- Investigar los efectos combinados de la raza/etnicidad y la depresión en las HLM.
- Examinar cómo estos factores afectan la función cognitiva en adultos mayores.
Principales métodos:
- Utilizó datos de 2411 adultos mayores del Centro Nacional de Coordinación de la Enfermedad de Alzheimer.
- Empleó regresiones lineales para analizar la carga de WMH y las asociaciones cognitivas a través de grupos raciales / étnicos y de depresión.
Principales resultados:
- Los adultos mayores negros e hispanos con depresión exhibieron una mayor carga de WMH en comparación con aquellos sin depresión.
- La depresión alteró significativamente la asociación entre WMH y deterioro cognitivo en individuos negros e hispanos.
- Estos efectos no se observaron en adultos mayores blancos.
Conclusiones:
- La raza y la depresión pueden interactuar para influir en la carga de enfermedades cerebrovasculares.
- Esta interacción también puede afectar la relación entre los WMH y la cognición en el envejecimiento y la demencia.

02:49Classifying Matter by State
104.6K
Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

01:05Long-term Depression
33.4K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.

02:35RACE - Rapid Amplification of cDNA Ends
7.3K
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific...

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
