Short-distance Transport of Resources02:12

Short-distance Transport of Resources

17.6K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Anatomy of the Ear01:16

Anatomy of the Ear

11.3K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Setting Time of Cement01:12

Setting Time of Cement

619
The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

Xylem and Transpiration-driven Transport of Resources

26.4K
The xylem of vascular plants distributes water and dissolved minerals that are taken up by the roots to the rest of the plant. The cells that transport xylem sap are dead upon maturity, and the movement of xylem sap is a passive process.

Endoscopic Studies II: Thoracocentesis

1.3K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Endoscopic Procedures I: Esophagogastroduodenoscopy

1.0K
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Area of Science:

  • Otolaryngology
  • Surgical Education

Background:

  • Endoscopic ear surgery is gaining popularity due to its advantages in low-resource settings, including ease of equipment transport and potential for telemedicine.
  • Patient benefits may include reduced post-operative pain and suitability for outpatient procedures.

Purpose of the Study:

  • To assess the efficacy of the Ear Trainer for training and evaluating endoscopic ear surgery skills.
  • Focus on application in a low-resource setting with ENT trainees.

Main Methods:

  • The Ear Trainer, previously validated for otology skills, was used to train and assess ENT trainees in Uganda.
  • Participants had limited practice time and no prior endoscopic experience.

Main Results:

  • Trainees showed significant improvements in instrument movement efficiency and camera view steadiness.
  • Overall task performance and speed of task completion (performance time) also improved.

Conclusions:

  • The Ear Trainer is a valuable tool for endoscopic ear surgery training and assessment.
  • It demonstrates utility in low-resource environments for developing surgical skills.
