The Actin Cytoskeleton and Actin-Based Motility.
Cold Spring Harbor Perspectives in Biology, 2018 The actin cytoskeleton-a collection of actin filaments with their accessory and regulatory proteins-is the primary force-generating machinery in the cell.

Clustering of bacteria with heterogeneous motility [PDF]
Physical Review E 101 (2020) 022612, 2020 We study the clustering of a model cyanobacterium \textit{Synechocystis} into microcolonies. The bacteria are allowed to diffuse onto surfaces of different hardness, and interact with the others by aggregation and detachment. We find that soft surfaces give rise to more microcolonies than hard ones. This effect is related to the amount of heterogeneity

Clinically relevant enhancement of human sperm motility using compounds with reported phosphodiesterase inhibitor activity [PDF]
, 2014 STUDY QUESTION: Can we identify compound(s) with reported phosphodiesterase inhibitor (PDEI) activity that could be added to human spermatozoa in vitro to enhance their motility without compromising other sperm functions?

Effect of motility on the transport of bacteria populations through a porous medium [PDF]
Phys. Rev. Fluids 4, 013102 (2019), 2018 The role of activity on the hydrodynamic dispersion of bacteria in a model porous medium is studied by tracking thousands of bacteria in a microfluidic chip containing randomly placed pillars. We first evaluate the spreading dynamics of two populations of motile and non-motile bacteria injected at different flow rates.

Spontaneous membrane formation and self-encapsulation of active rods in an inhomogeneous motility field [PDF]
, 2018 We study the collective dynamics of self-propelled rods in an inhomogeneous motility field. At the interface between two regions of constant but different motility, a smectic rod layer is spontaneously created through aligning interactions between the ...

Fixation eye movement abnormalities and stereopsis recovery following strabismus repair
Scientific Reports, 2021 We evaluated the effects of strabismus repair on fixational eye movements (FEMs) and stereopsis recovery in patients with fusion maldevelopment nystagmus (FMN) and patients without nystagmus.

Dynamic clustering of passive colloids in dense suspensions of motile bacteria [PDF]
, 2021 Mixtures of active and passive particles are predicted to exhibit a variety of nonequilibrium phases. Here we report a dynamic clustering phase in mixtures of colloids and motile bacteria. We show that colloidal clustering results from a balance between bond breaking due to persistent active motion and bond stabilization due to torques that align ...

Effects of in vitro lipid overload on LX-2 hepatic stellate cells
Annals of Hepatology, 2022 Introduction and Objectives: Studying lipid overload repercussions on hepatic stellate cells (HSC) is of great importance due to their role in fibrosis during NAFLD. Steatogenic cell culture of HSC is intended to elucidate pathogenic mechanisms in NAFLD.
