Lung Capacity01:47

Lung Capacity

56.3K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

pre-mRNA Processing02:01

pre-mRNA Processing

57.5K
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...

Chromatin Structure Regulates pre-mRNA Processing

8.2K
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.
The chromatin structure, especially...

Tracheostomy Care I: Pre-procedural Steps

1.1K
A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.

Area of Science:

  • Pulmonary Medicine
  • Medical Imaging
  • Thoracic Surgery

Background:

  • Chronic obstructive pulmonary disease (COPD) is a major global health issue with significant morbidity and mortality.
  • Lung volume reduction surgery (LVRS) is a treatment for severe emphysema, but requires precise patient selection.
  • Current preoperative imaging methods for lobar function assessment are anatomically inaccurate.

Purpose of the Study:

  • To develop and validate a novel hybrid imaging technique for quantitative lobar ventilation and perfusion assessment.
  • To demonstrate the utility of this technique in preoperative profiling and surgical planning for LVRS.
  • To compare the efficacy of the hybrid technique against conventional imaging modalities.

Main Methods:

  • Development of a hybrid imaging approach combining Single Photon Emission Tom Tomography (SPECT) with Computed Tomography (CT).
  • Quantitative characterization of regional lung ventilation and perfusion at the lobar level.
  • Technical validation of the hybrid imaging methodology.

Main Results:

  • The SPECT/CT hybrid technique provides accurate, anatomy-based, quantitative lobar ventilation and perfusion data.
  • This method offers superior results compared to traditional planar imaging for LVRS planning.
  • Demonstrated utility in disease profiling, surgical planning, and predicting postoperative outcomes.

Conclusions:

  • Hybrid SPECT/CT imaging is a valuable tool for precise preoperative evaluation in patients undergoing LVRS.
  • This advanced imaging technique enhances surgical planning and improves patient outcome prediction for emphysema.
  • The developed methodology offers a significant advancement over conventional imaging in thoracic surgery.
