Trabecular meshwork (TM) migration into Schlemm’s canal space can be induced by acute pressure elevation by ophthalmodynamometer, and observed by spectral domain optical coherence tomography. The goal of this method is to quantify the morphometric response of the living outflow tract to acute pressure elevation in living tissues in situ.

Outer-Boundary Assisted Segmentation and Quantification of Trabecular Bones by an Imagej Plugin
0 Views •
2018
We present a workflow for segmenting and quantifying trabecular bones for 2D and 3D images based on the bone's outer boundary using an ImageJ plugin. This approach is more efficient and accurate than the current manual hand-contouring approach, and provides layer-by-layer quantifications, which are not available in current commercial software.

In some cases, like the 2005 Banda Ache earthquake in Indonesia, the damage involved large geographic areas and casualties in the six figures. In general, the number and intensity of earthquakes is not increasing, however, the vulnerability of the built environment is...

Source: Tamara M. Powers, Department of Chemistry, Texas A&M University In 1951, Kealy and Pauson reported to Nature the synthesis of a new organometallic compound, ferrocene.1 In their original report, Pauson suggested a structure for ferrocene in which the iron is singly bonded (sigma bonds) to one carbon atom of each cyclopentadiene ligand (Figure 1, Structure I).1,2,3 This initial report led to wide-spread interest in the structure of ferrocene, and many leading scientists participated...
FAQs
Notch-mediated pathways participate in signaling between the endocardium and myocardium as ventricular cardiomyocytes grow and differentiate. This communication helps coordinate the formation of internal projections rather than allowing cellular changes to occur independently. Examining this pathway therefore connects molecular signaling with the emergence of organized chamber architecture and provides a basis for understanding disrupted cardiac development.
Coordinated growth and differentiation allow ventricular cardiomyocytes to form an ordered internal architecture while the embryonic heart is still developing. If these processes were considered separately, the relationship between cell state and tissue organization would be missed. Their integration helps explain how developing chambers acquire structures capable of supporting force generation and exchange before the coronary circulation is fully established.
The internal network contributes to embryonic cardiac performance in two complementary ways. Its organized projections help the developing ventricle generate force, while the expanded internal surface supports oxygen and nutrient exchange at a stage when coronary circulation has not fully developed. Thus, architecture is not merely structural; it is linked directly to early physiological requirements.
Examining trabecular structure provides a way to connect cellular development with the changing organization of heart chambers. Researchers can consider how cardiomyocyte growth, differentiation, and endocardial-myocardial signaling contribute to chamber architecture and function. This perspective helps clarify maturation as an interaction between developmental programs and tissue arrangement, rather than as a simple increase in chamber size.
Abnormal trabecular development can be considered in relation to congenital cardiac defects because the process depends on coordinated signaling, cardiomyocyte differentiation, and chamber organization. Studying these relationships helps identify how developmental changes might disrupt the architecture required for early cardiac force generation or exchange. The subject therefore links tissue-level abnormalities with mechanisms operating during heart formation.
Trabecular structure demonstrates that the arrangement of cells and projections can influence organ function during development. In the embryonic heart, architecture supports both mechanical performance and exchange while circulation is still developing. This example gives developmental biology a direct framework for studying how signaling and cell behavior produce tissue forms with specific functional consequences.
