Solution Composition During Acid/Base Titrations01:17

Solution Composition During Acid/Base Titrations

1.5K
The titration of a weak acid with a strong base results in the formation of water and the conjugate base of the acid. For instance, titrating acetic acid with sodium hydroxide leads to the formation of water and sodium acetate. A solution of acetic acid and sodium acetate constitutes a buffer whose relative concentration at different stages of the titration is indicated by the α values, which represent percentages of the weak acid and its conjugate base.
The α0 and α1 values...

Sex-linked Disorders01:43

Sex-linked Disorders

108.5K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

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. 
A mixture is composed of two or...

Difference from Background: Limit of Detection01:05

Difference from Background: Limit of Detection

8.1K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

Electric Potential and Potential Difference01:16

Electric Potential and Potential Difference

5.6K
Suppose a positive test charge moves away from a positive static charge, then the Coulomb force does positive work, and its electric potential energy decreases. The potential energy per unit charge is defined as the electric potential. The electric potential is independent of the test charge.
When a test charge moves from the initial to the final position, the electric potential difference between those positions is defined as the ratio of the change in the potential energy to the charge on the...

Identifying Statistically Significant Differences: The F-Test01:14

Identifying Statistically Significant Differences: The F-Test

3.3K
The F-test is used to compare two sample variances to each other or compare the sample variance to the population variance. It is used to decide whether an indeterminate error can explain the difference in their values. The underlying assumptions that allow the use of the F-test include the data set or sets are normally distributed, and the data sets are independent of each other. The test statistic F is calculated by dividing one variance by another. In other words, the square of one standard...

Diferencias basadas en el sexo en la composición del trombo en el accidente cerebrovascular isquémico agudo

Resumen

El sexo influye de forma independiente en los porcentajes de glóbulos blancos (GB) en los trombos de accidente cerebrovascular isquémico agudo. Las diferencias en la composición de fibrina y glóbulos rojos (GR) entre sexos pueden estar relacionadas con el recuento de GR, no con el sexo en sí.

Área de la Ciencia:

  • Neurología
  • Patología
  • Ingeniería Biomédica

Sus antecedentes:

  • La trombectomía endovascular permite el análisis detallado de la composición del trombo en el accidente cerebrovascular isquémico agudo.
  • Las variaciones en la composición del trombo pueden influir en los resultados del paciente.
  • Las diferencias reconocidas en la fisiología de la coagulación entre sexos justifican la investigación de las variaciones en la composición del trombo basadas en el sexo.

Objetivo del estudio:

  • Investigar posibles diferencias basadas en el sexo en la composición histológica de trombos de pacientes con accidente cerebrovascular isquémico agudo.
  • Determinar si el sexo es un predictor independiente de la composición del trombo.

Principales métodos:

  • Análisis retrospectivo de 73 pacientes sometidos a trombectomía endovascular por accidente cerebrovascular isquémico agudo.
  • Los trombos se tiñeron (hematoxilina y eosina) para cuantificar los porcentajes de fibrina, glóbulos rojos (GR) y glóbulos blancos (GB).
  • Se realizaron análisis univariados y multivariantes, ajustando por variables relevantes.

Principales resultados:

  • Los pacientes varones tuvieron porcentajes más altos de GR (51,5%) en comparación con las mujeres (33,8%).
  • Las pacientes presentaron porcentajes más altos de fibrina (58,3%) y GB (6,5%) que los varones (45,1% y 4,4%, respectivamente).
  • El análisis multivariante reveló que el sexo es un predictor independiente solo para el porcentaje de GB, mientras que el recuento de GR predijo de forma independiente los porcentajes de fibrina y GR.

Conclusiones:

  • El sexo es un determinante independiente del porcentaje de glóbulos blancos (GB) en los trombos de accidente cerebrovascular isquémico agudo.
  • No se encontraron asociaciones independientes entre el sexo y los porcentajes de fibrina o glóbulos rojos (GR), lo que sugiere una mediación por el recuento de GR.
  • La investigación futura debe incorporar el sexo y los valores de laboratorio basales al estudiar la composición del trombo.
