Mechanistic Insight into the Internalization, Distribution, and Autophagy Process of Manganese Nanoparticles in L.: Evidence from Orthogonal Microscopic Analysis.

Orthogonal techniques were used to track manganese nanoparticles (MnNPs) in L. leaf tissue and cell compartments and subsequently to explain the mechanism of uptake, translocation, and cellular interaction. L was cultivated and foliarly exposed to MnNPs (100 mg/L, 50 mL/per leaf) before analysis by using scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDS) as well as dark-field hyperspectral and two-photon microscopy.

A Model for Studying the Biomechanical Effects of Varying Ratios of Collagen Types I and III on Cardiomyocytes.

Purpose: To develop a novel model composed solely of Col I and Col III with the lower and upper limits set to include the ratios of Col I and Col III at 3:1 and 9:1 in which the structural and mechanical behavior of the resident CM can be studied. Further, the progression of fibrosis due to change in ratios of Col I:Col III was tested.

Methods: Collagen gels with varying Col I:Col III ratios to represent a healthy (3:1) and diseased myocardial tissue were prepared by manually casting them in wells.
