Physics of Rheologically-Enhanced Propulsion: Different Strokes in Generalized Stokes [PDF]
Shear-thinning is an important rheological property of many biological fluids, such as mucus, whereby the apparent viscosity of the fluid decreases with shear.

Molecular anatomy of emerging Xenopus left–right organizer at successive developmental stages
Abstract Background Vertebrate left–right symmetry breaking is preceded by formation of left–right organizer. In Amphibian, this structure is formed by gastrocoel roof plate, which emerges from superficial suprablastoporal cells. GRP is subdivided into medial area, which generates leftward flow by rotating monocilia and lateral Nodal1 expressing areas,

Abstract Background Mouse nodal immotile cilia mechanically sense the bending direction for left–right (L–R) determination and activate the left‐side‐specific signaling cascade, leading to increased Nodal activity. Asymmetric distribution of Pkd2, a crucial channel for L–R determination, on immotile cilia has been reported recently. However, the causal

Fluid motion induced by surface waves at low Reynolds number [PDF]
We discuss the scaling laws for the flow generated in a viscous fluid by a wave propagating along a solid boundary. This has applications to the displacement of tiny objects on solids, under the effect of progressive surface waves and for the swimming of microanimals by undulation of ciliae along their body surface.

Asymmetric Rotational Stroke in Mouse Node Cilia during Left-Right Determination [PDF]
Clockwise rotational movement of isolated single cilia in mice embryo was investigated in vivo. The movement generates leftward fluid flow in the node cavity and plays an important role in left-right determination. The leftward unidirectional flow results from tilting of the rotational axis of the cilium to posterior side.

Interleukin-1β sequesters hypoxia inducible factor 2α to the primary cilium. [PDF]
BACKGROUND: The primary cilium coordinates signalling in development, health and disease. Previously we have shown that the cilium is essential for the anabolic response to loading and the inflammatory response to interleukin-1β (IL-1β).

ABSTRACT Aquaporin‐4 (AQP4) is a water‐selective channel expressed in glial cells throughout the central nervous system (CNS). It serves as the primary water channel in the neuropil and plays roles in physiological functions, including regulating water homeostasis by adjusting cell volume and modulating neuronal activity. Different isoforms of AQP4 are

Heat shock induces rapid resorption of primary cilia [PDF]
Primary cilia are involved in important developmental and disease pathways, such as the regulation of neurogenesis and tumorigenesis. They function as sensory antennae and are essential in the regulation of key extracellular signalling systems.

Abstract Objective This study aimed to explore genetic etiologies of conotruncal defects (CTDs) in fetuses by analyzing the results of different genetic tests and to assess pregnancy outcomes of fetuses with CTD in a Chinese prenatal cohort. Methods A total of 146 fetuses that underwent invasive prenatal genetic testing for CTD at the prenatal ...
