We have determined the microanatomy of the cervix in relation to elastic fibers by serial dissection of human cervix in three tissue planes: cross, sagittal, and frontal sections. Analysis suggests that elastin is localized to specific regions of the uterine cervix and not dispersed throughout the connective tissue stroma. By Musto stain the majority of elastic fibers are noted to be oriented from the external os to the periphery and from there in a band upward toward the internal os where they become sparse in the area of the cervix with the greatest amount of smooth muscle just below the internal os. Elastic fibers were noted to be sparsely distributed in the cervical stroma.

Purpose: Shear wave elastography (SWE) provides a means for adding information about the mechanical properties of tissues to a diagnostic ultrasound examination. It is important to understand the physics and methods by which the measurements are made to aid interpretation of the results as they relate to disease processes.
Methods: The components of how ultrasound is used to generate shear waves and make measurements of the induced motion are reviewed.

C-C chemokine receptor type 2 (CCR2) cardiac-resident macrophages (CCR2 cRMs) are known to promote cardiac repair after myocardial infarction (MI). However, the substantial depletion and slow recovery of CCR2 cRMs pose significant barriers in cardiac recovery. Here, we construct a functional conductive cardiac patch (CCP) that can provide exogenously elastic conductive microenvironment and induce endogenously reparative microenvironment mediated by CCR2 cRMs for MI repair.

Athermal (i.e., zero-temperature) underconstrained systems are typically floppy, but they can be rigidified by the application of external strain, which is theoretically well understood.

Zinc (Zn) and its alloys have been the focus of recent materials and manufacturing research for orthopaedic implants due to their favorable characteristics including desirable mechanical strength, biodegradability, and biocompatibility. In this research, a novel process involving additive manufacturing (AM) augmented casting was employed to fabricate zinc-magnesium (Zn-0.8 Mg) artifacts with surface lattices composed of triply periodic minimal surfaces (TPMS), specifically gyroid.

The human body consists of many different soft biological tissues that exhibit diverse microstructures and functions and experience diverse loading conditions. Yet, under many conditions, the mechanical behaviour of these tissues can be described well with similar nonlinearly elastic or inelastic constitutive relations, both in health and some diseases. Such constitutive relations are essential for performing nonlinear stress analyses, which in turn are critical for understanding physiology, pathophysiology and even clinical interventions, including surgery.
