Increased Body Temperature01:25

Increased Body Temperature

6.4K
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Methods of reducing fever01:22

Methods of reducing fever

1.6K
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Burn Injuries01:22

Burn Injuries

4.4K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Drugs for Treatment of Ulcerative Colitis in IBD01:29

Drugs for Treatment of Ulcerative Colitis in IBD

705
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Gastritis III: Clinical Manifestations and Management

1.9K
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Healing I: Introduction01:11

Healing I: Introduction

14
Healing is the physiological process by which the body restores the integrity and function of damaged tissues following injury. It involves a coordinated interplay of cellular proliferation, extracellular matrix remodeling, and growth factor signaling. The extent and nature of the tissue damage determine whether healing occurs by resolution, regeneration, or replacement.ResolutionResolution represents the most complete form of healing, occurring when the injury is minimal and tissue...

Resumen
Este resumen es generado por máquina.

La inflamación persistente impulsa la enfermedad al dañar los tejidos. Si bien el cuerpo tiene mecanismos de resolución, su fracaso, especialmente en respuestas inflamatorias excesivas o insuficientes, complica el desarrollo de la terapia antiinflamatoria.

  • Investigación biomédica en la investigación biomédica.

Sus antecedentes:

  • La inflamación no resuelta es un factor significativo en el desarrollo de la enfermedad.
  • La inflamación puede causar daño tisular, y la necrosis puede provocar aún más respuestas inflamatorias.
  • A pesar de los riesgos, el cuerpo posee múltiples mecanismos para asegurar la resolución inflamatoria.

Objetivo del estudio:

  • Para explorar los mecanismos que subyacen a la resolución inflamatoria.
  • Identificar los factores que contribuyen al fracaso de la resolución inflamatoria.
  • Para abordar los desafíos en el desarrollo de terapias antiinflamatorias.

Principales métodos:

  • Intercambio de fenotipo celular investigado (por ejemplo, macrófagos).
  • Examinó el papel de las moléculas secretadas (por ejemplo, los intermediarios reactivos de oxígeno) en la modulación de la inflamación.
  • Identificó mediadores emergentes de la resolución, incluidas proteínas, lípidos y gases.

Principales resultados:

  • La resolución normal implica cambios coordinados en las funciones celulares y moleculares.
  • La falta de resolución puede deberse a la intensidad inicial de la respuesta inflamatoria (excesiva o subnormal).
  • La persistencia de los estímulos iniciales también impide la resolución.

Conclusiones:

  • Desarrollar terapias antiinflamatorias efectivas es complejo debido a la naturaleza multifacética de la resolución de la inflamación.
  • Se necesitan innovaciones conceptuales, organizativas y estadísticas para avanzar en el desarrollo de fármacos antiinflamatorios.
  • Comprender las vías de resolución es crucial para el tratamiento de enfermedades inflamatorias.
