Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

2.9K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Adherens Junctions01:24

Adherens Junctions

5.8K
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types –  adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as  epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as  heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

3.8K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Diabetic Retinopathy

65
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

45
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Encephalitis ll: Pathophysiology01:26

Encephalitis ll: Pathophysiology

30
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

Resumen

Las infecciones infantiles agudas perjudican la función de los vasos sanguíneos, un paso clave en la etapa temprana de la aterosclerosis. Esto sugiere que las infecciones pueden desempeñar un papel en el desarrollo de esta condición desde una edad temprana.

  • Investigación Cardiovascular Investigación Cardiovascular Investigación Cardiovascular Investigación Cardiovascular Investigación Cardiovascular
  • Inmunología Inmunología.

Sus antecedentes:

  • La aterosclerosis se origina en la infancia, con la disfunción endotelial como un evento inicial crítico.
  • La influencia de las infecciones agudas de la infancia en el endotelio vascular sigue siendo en gran medida desconocida.

Objetivo del estudio:

  • Investigar el impacto de las infecciones infantiles comunes agudas en la función endotelial.
  • Para determinar si las infecciones contribuyen a los cambios vasculares tempranos asociados con la aterosclerosis.

Principales métodos:

  • Estudió a 600 niños de 10 años del Estudio Longitudinal Avon de Padres e Hijos.
  • Se evaluó la función endotelial utilizando la dilatación mediada por flujo de la arteria braquial (FMD) a través de ultrasonido de alta resolución.
  • Comparación de la fiebre aftosa en niños con infección aguda, infección reciente (convalescente) y controles sanos.

Principales resultados:

  • Los niños con infección aguda (IA) y los niños convalecientes exhibieron una fiebre aftosa significativamente menor en comparación con los controles sanos (P <0,001).
  • Estas diferencias persistieron después de ajustar por factores de confusión.
  • En los niños con infección aguda, la fiebre aftosa mejoró significativamente después de un año, mientras que los controles se mantuvieron sin cambios.

Conclusiones:

  • Las infecciones infantiles agudas están vinculadas a una vasodilatación dependiente del endotelio deteriorada.
  • Los hallazgos sugieren que los estímulos inflamatorios extrínsecos, como las infecciones, pueden contribuir a la patogénesis de la aterosclerosis en etapa temprana.
