High-speed in vitro intensity diffraction tomography [PDF]

open access: yes, 2019
We demonstrate a label-free, scan-free {\it intensity} diffraction tomography technique utilizing annular illumination (aIDT) to rapidly characterize large-volume 3D refractive index distributions in vitro. By optimally matching the illumination geometry to the microscope pupil, our technique reduces the data requirement by 60$\times$ to achieve high ...

Properties of Chromatin in Human Cells as Characteristics of the State of Human Organism: A Review [PDF]

open access: yesAdv Complement Alt Med. 1(1). ACAM.000505. 2018. http://crimsonpublishers.com/acam/volume1-issue1-acam.php, 2018
The state of chromatin in individual cells is directly related to the state of the whole organism and may be used for assessment of the state of the whole organism. Many hereditary diseases are connected with chromatin rearrangements. Chromatin distribution in cell nucleus is an important characteristic which may be applied for determination of disease

Dynamic Properties of Human Bronchial Airway Tissues [PDF]

open access: yesarXiv, 2011
Young's Modulus and dynamic force moduli were measured on human bronchial airway tissues by compression. A simple and low-cost system for measuring the tensile-strengh of soft bio-materials has been built for this study. The force-distance measurements were undertaken on the dissected bronchial airway walls, cartilages and mucosa from the surgery ...
