Oxygen Delivering System III: Tracheostomy and T-piece01:23

Oxygen Delivering System III: Tracheostomy and T-piece

6.3K
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Oxygen Delivering System I: Nasal Cannula and Face Mask

1.7K
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

2.4K
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.9K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Targets for Drug Action: Overview

10.4K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Target Cell Response to Hormones01:22

Target Cell Response to Hormones

5.8K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Resumen
Este resumen es generado por máquina.

Las nanopartículas de conversión ascendente (UCNPs, por sus siglas en inglés) permiten la administración de fármacos a los tejidos profundos, activada por la luz, utilizando luz de infrarrojo cercano (NIR, por sus siglas en inglés). Esto supera las limitaciones de la luz UV / Vis para aplicaciones terapéuticas precisas y no invasivas.

  • El uso de estas emisiones para desencadenar la liberación localizada de fármacos y para la bioimagen.

Principales resultados:

  • Los UCNP permiten la liberación de fármacos provocada por la luz NIR, que penetra en los tejidos más profundamente que la luz UV/Vis.
  • Este enfoque permite la administración precisa y bajo demanda del medicamento en lugares específicos dentro del cuerpo.
  • Los UCNP sirven como fuentes de luz in situ efectivas tanto para la liberación de fármacos como para aplicaciones de bioimagen.

Conclusiones:

  • Los sistemas de administración de fármacos activados por NIR mediados por UCNP representan un avance significativo con respecto a los métodos tradicionales controlados por luz.
  • Estos sistemas ofrecen aplicaciones prometedoras en anestesia, cicatrización de heridas, cirugía y tratamiento del cáncer.
  • Se necesitan más investigaciones y desarrollos para facilitar la traducción clínica de la administración de fármacos basada en UCNP.
