A preliminary study of liver fat quantification using reported longitudinal ultrasound speed of sound and attenuation parameters [PDF]
arXiv, 2021 The quantification of liver fat as a diagnostic assessment of steatosis remains an important priority for noninvasive imaging systems. We derive a framework in which the unknown fat volume percentage can be estimated from a pair of ultrasound measurements. The precise estimation of ultrasound speed of sound and attenuation within the liver are shown to

Digital holographic microscopy for the evaluation of human sperm structure [PDF]
Zygote / FirstView Article, pp 1-9, Cambridge University Press
2013, Published online: 07 March 2013, 2013 The morphology of the sperm head has often been correlated with the outcome of in vitro fertilization (IVF), and has been shown to be the sole parameter in semen of value in predicting the success of intracytoplasmic sperm injection (ICSI) and intracytoplasmic morphologically selected sperm injection (IMSI).

Characterizations of individual mouse red blood cells parasitized by Babesia microti using 3-D holographic microscopy [PDF]
arXiv, 2015 Babesia microti causes emergency human babesiosis. However, little is known about the alterations in B. microti invaded red blood cells (Bm-RBCs) at the individual cell level. Through quantitative phase imaging techniques based on laser interferometry, we present the simultaneous measurements of structural, chemical, and mechanical modifications in ...

Laser induced topological cues shape, guide, and anchor human Mesenchymal Stem Cells [PDF]
arXiv, 2018 This report focuses on the effect of the surface topography of the substrate on the behavior of human mesenchymal stem cells from bone marrow (MSCs) before and after co-differentiation into adipocytes and osteoblasts. Picosecond pulsed laser ablation technology was applied to generate different microstructures (microgrooves and microcavities) on poly ...

Membrane tubes with active pumping: water transport, vacuole formation and osmoregulation [PDF]
arXivThe need for organisms to regulate their volume and osmolarity when surrounded by freshwater is a basic physical challenge for many bacteria, protists and algae. Taking inspiration from the contractile vacuole complex found in many protists, we discuss how simple models of active membrane tubes can give insights into the fluid and active ionic ...
