Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In a staggeringly complex and engaging world, it is crucial to selectively process some stimuli at the expense of others. Experimental psychologists call this ability attention. Specifically, visual attention refers to the ability to selectively process aspects of a visual scene. Many paradigms used to study visual attention involve brief, punctuated, and repeated trials. However, everyday situations often place sustained demands...

To date, thick tissue defects are typically reconstructed by applying autologous tissue flaps or engineered tissues. In this protocol, we present a new method for engineering vascularized tissue flap bearing an autologous pedicle, to serve as a substitute to autologous flaps.

An accurate and practical method to measure parameters like strain in myocardial tissue is of great clinical value, since it has been shown, that strain is a more sensitive and earlier marker for contractile dysfunction than the frequently used parameter EF.

Tools used for visualizing vascular regeneration require methods for contrasting the vascular trees. This film demonstrated a delicate injection technique used to achieve optimal contrasting of the vascular trees and illustrate the potential benefits resulting from a detailed analysis of the resulting specimen using µCT and histological serial sections.

Eye Tracking in Cognitive Experiments

Eye tracking as the name suggests involves tracking of eye-movements. It is a non-invasive, sensitive tool that quantifies and measures eye-movements to describe an individuals' cognitive state. An eye-movement between two fixation points is called a saccade, which is one of the fastest motor movements in our body. By observing the profiles of these eye movements, scientists can better understand neural deficits in patients with cognitive impairments. In this video, we will first look at an...
FAQs
Structural observations, such as vessel diameter and wall characteristics, show how the vessel itself changes, while functional measures, including blood flow and perfusion, indicate how effectively it supports circulation. Examining both dimensions can reveal whether remodeling is accompanied by altered hemodynamics, giving clinicians and researchers a more complete view of vascular status than either measurement alone.
A baseline provides the reference point against which later vascular observations are compared. Without it, an observed diameter, flow pattern, perfusion value, or wall feature is harder to interpret as stable, improved, or abnormal for that individual. Consistent baseline comparisons therefore help distinguish meaningful deviations from the person’s earlier vascular state.
Repeated observations can reveal gradual progression, improvement, or persistent deviation that may not be apparent in one assessment. Tracking several time points also helps connect structural remodeling with changing blood flow or perfusion. These patterns support earlier recognition of clinically meaningful vascular change and provide stronger evidence for evaluating disease behavior over time.
Vascular remodeling describes changes in vessel structure, whereas hemodynamic changes concern blood movement and perfusion. Tracking both allows researchers to examine whether structural alterations correspond with altered circulation. This relationship is important because vascular disease may involve changes in the vessel wall and changes in how blood moves through the circulation, with each offering complementary information.
The process begins by recording relevant vascular observations at an initial time point, then repeating comparable assessments later. Measurements may include vessel diameter, blood flow, perfusion, and wall characteristics. Investigators compare each observation with the baseline and with prior time points, looking for consistent trends or deviations that warrant clinical or research interpretation.
Vascular Changes Tracking can be used when clinicians need to determine whether treatment is associated with improvement, stability, or continued vascular deterioration. Comparing measurements before and after treatment provides evidence about changes in circulation, vessel structure, or function. The longitudinal perspective is especially useful when the response cannot be judged reliably from a single assessment.
Longitudinal monitoring gives researchers a way to connect vascular remodeling and hemodynamic changes with patient outcomes. By following observations across multiple time points, studies can examine whether particular vascular trends accompany disease progression or clinically important outcomes. This supports a more detailed understanding of cardiovascular and other vascular disorders than isolated measurements provide.
The approach is relevant to medical conditions that affect the vasculature, not only disorders centered on the heart and circulation. Monitoring vessel structure and function can help assess disease progression, evaluate treatment effects, and identify changes earlier when vascular involvement is clinically important. Its value comes from relating evolving vascular findings to the broader course of illness.
