Frictional Active Brownian Particles
, 2020 Frictional forces affect the rheology of hard-sphere colloids, at high shear rate. Here we demonstrate, via numerical simulations, that they also affect the dynamics of active Brownian particles, and their motility induced phase separation.

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?

Journal of the American Medical Association, 1917 To the Editor: —In the Current Comment on "The Function of the Prostate" (The Journal, Feb. 17, 1917, p. 553), it is stated that "it has been noted that the spermatozoa are practically motionless while in the seminiferous tubules of the testis, but become actively motile in the vas deferens, or when mixed with prostatic secretion." The statement that

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 ...

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.

Interactions of Little-brain and Big-brain in Explaining Abdominal Symptoms
International Journal of Endorsing Health Science Research, 2022 For a long time, the role of an extensive neurological network in the gut (the little-brain) has been under-recognized because the enteric nervous system (ENS) is thought to have little impact beyond digestion.

Polarized cell motility induces hydrogen peroxide to inhibit cofilin via cysteine oxidation [PDF]
, 2015 Mesenchymal cell motility is driven by polarized actin polymerization [1]. Signals at the leading edge recruit actin polymerization machinery to promote membrane protrusion, while matrix adhesion generates tractive force to propel forward movement.

The Shape of Motile Cells [PDF]
Current Biology, 2009 Motile cells - fan-like keratocytes, hand-shaped nerve growth cones, polygonal fibroblasts, to name but a few - come in different shapes and sizes. We discuss the origins of this diversity as well as what shape tells us about the physics and biochemistry underlying cell movement.
