Summary
Completing breast reconstructions with nipple-areola complexes shifts viewer attention from scars to a holistic assessment, improving aesthetic perception. Eye-tracking technology objectively measures gaze to predict aesthetic preferences in plastic surgery.
Area of Science:
- Plastic and Reconstructive Surgery
- Ophthalmology
- Human-Computer Interaction
Background:
- Aesthetics significantly influences outcomes in plastic and reconstructive surgery.
- Understanding viewer perceptions of aesthetics is key to patient satisfaction.
- Eye-tracking technology provides an objective method for evaluating aesthetic perception.
Purpose of the Study:
- To investigate how viewers perceive aesthetic outcomes in breast reconstructions using eye-tracking technology.
- To analyze the impact of nipples and scars on visual attention during aesthetic evaluation.
- To determine if eye-tracking data can predict subjective aesthetic preferences.
Main Methods:
- Twenty-nine raters with varying plastic surgery experience viewed 20 images of breast reconstructions.
- Images depicted breasts with varying combinations of nipples and scars.
- Eye-tracking equipment recorded viewer gaze patterns for 8 seconds per image.
Main Results:
- Viewers focused 53.9% of attention on scars when nipples were absent.
- Attention was divided between nipples (27.5%) and scars (27.7%) when both were present.
- Complete reconstructions led to broader scanning and less fixation on scars.
Conclusions:
- The nipple-areola complex is crucial for restoring normal viewing patterns in breast reconstructions.
- Completed reconstructions with nipple-areola complexes redirect attention from scars, promoting holistic evaluation.
- Eye-tracking offers a robust link between objective gaze and subjective aesthetic preferences.

01:29Assessment of the Gastrointestinal System II: Health Perception Pattern
508
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

01:06Fixed Action Patterns
17.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

17.8K
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

01:10Reconstruction of Signal using Interpolation
746
Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

4.6K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...
