Introduction to Structures01:30

Introduction to Structures

A structure is defined as a system of interconnected members designed to support or transfer forces and successfully withstand the loads acting on them. The internal forces of a structure can be determined by decomposing the structure and analyzing the free-body diagrams of the individual members or of a combination of members. This helps in understanding the structural elements' behavior and ensuring that the structure is stable and can withstand the subjected loads.

Anchoring Junctions01:03

Anchoring Junctions

Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...

Overview of Cell-Cell Junctions

The complex three-dimensional arrangement of cells in any multicellular organism is defined and maintained by interactions of cells with each other and the extracellular matrix. Cell-cell junctions are specialized structures where the multi-protein complexes on one cell interact with the multi-protein complexes on another  cell. These cell junctions are classified  into three main types based on their function — occluding, anchoring, and gap junctions.

Functions of Connective Tissues01:17

Functions of Connective Tissues

Connective tissues perform a broad range of functions in the body. Their primary function is to connect and link different tissues in the body and act as packaging material between tissues. The areolar tissue, a connective tissue prototype, commonly cements various tissue types in diverse body organs. In contrast, adipose tissue cushions internal organs while insulating the body from heat loss.
Hard connective tissues, such as bones and cartilage, provide structure and support to the body.
Circuit Terminology01:14

Circuit Terminology

An electrical network is a system composed of interconnected elements, such as resistors, capacitors, inductors, and voltage or current sources. Unlike a circuit, an electrical network does not necessarily form a closed path. In other words, while all circuits can be considered networks due to their interconnected nature, not every network qualifies as a circuit.
A circuit, on the other hand, is also an interconnected system of electrical elements but must contain one or more closed paths.

Area of Science:

  • Neuroscience
  • Developmental Pediatrics
  • Medical Imaging

Background:

  • Most very preterm-born infants experience cognitive challenges.
  • Early prediction of these difficulties is essential for targeted interventions.

Purpose of the Study:

  • To identify early predictors of cognitive outcomes in very preterm infants.
  • To understand the neurodevelopmental trajectory of preterm-born children.

Main Methods:

  • Multimodal structural and functional magnetic resonance imaging (MRI) in preterm infants.
  • Longitudinal behavioral and neuroimaging assessments up to 4 years of age.
  • Neuroimaging in school-aged preterm children.

Main Results:

  • Early MRI measures (preterm to term age) correlate with 2-year outcomes.
  • Both functional and structural brain differences are observed in school-aged preterm children.
  • Examples of these findings are presented.

Conclusions:

  • Longitudinal structural and functional MRI studies in preterm populations offer critical insights.
  • These studies help elucidate brain-behavior relationships.
  • Predicting outcomes in high-risk preterm individuals is facilitated by neuroimaging.
