Review of the anatomical basis for predicting plutonium alpha particle radiation induced osteogenic cancers

The Anatomical Record, EarlyView.
Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

BMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Nanostructured drug delivery systems for posterior segment eye diseases: Strategies to defy ocular barriers

BMEMat, EarlyView.
Efficient drug delivery to the posterior segment of the eye has long been a challenging issue due to the complex ocular barriers. The review focuses on the promise held by nanoplatforms for barrier penetration and the key mechanisms involved, also highlighting their advantages in achieving efficient drug delivery and superior treatment of PSEDs ...

The Wire Is Not the Territory: Understanding Representational Drift in Olfaction With Dynamical Systems Theory

Topics in Cognitive Science, EarlyView., 2023
Abstract Representational drift is a phenomenon of increasing interest in the cognitive and neural sciences. While investigations are ongoing for other sensory cortices, recent research has demonstrated the pervasiveness in which it occurs in the piriform cortex for olfaction.

Dynamics of primary cilia in endothelial and mesenchymal cells throughout mouse lung development

Developmental Dynamics, EarlyView.
Abstract Cilia are specialized structures found on a variety of mammalian cells, with variable roles in the transduction of mechanical and biological signals (by primary cilia, PC), as well as in the generation of fluid flow (by motile cilia). Their critical role in the establishment of a left–right axis in early development is well described, as well ...

Mechanisms underlying unidirectional laminar shear stress-mediated Nrf2 activation in endothelial cells: Amplification of low shear stress signaling by primary cilia

Redox Biology, 2021
Endothelial cells are sensitive to mechanical stress and respond differently to oscillatory flow versus unidirectional flow. This review highlights the mechanisms by which a wide range of unidirectional laminar shear stress induces activation of the ...

Activation of adenosine A_2B receptors enhances ciliary beat frequency in mouse lateral ventricle ependymal cells

Cerebrospinal Fluid Research, 2009
Background Ependymal cells form a protective monolayer between the brain parenchyma and cerebrospinal fluid (CSF). They possess motile cilia important for directing the flow of CSF through the ventricular system.

Interspecific comparisons of anuran embryonic epidermal landscapes and energetic trade‐offs in response to changes in salinity

Developmental Dynamics, EarlyView.
Abstract Background Freshwater salinization is an emerging stressor in amphibian populations, and embryonic stages are most vulnerable. To better understand the variation in embryonic osmoregulation, we challenged embryos of two phylogenetically diverse anuran species, Xenopus laevis and Lithobates (Rana) sylvaticus, along a gradient of non‐lethal ...

Ciliary propulsion of objects in tubes: wall drag on swimming Tetrahymena (Ciliata) in the presence of mucin and other long-chain polymers [PDF]

, 1976
The lubrication effect of three long-chain polymers - mucin, methylcellulose and Ficoll - on ciliary propulsion in tubes is measured by plotting the relative velocities of swimming cilitates as a function of the tube bore diameter.

Modelling the Fluid Mechanics of Cilia and Flagella in Reproduction and Development

, 2012
Cilia and flagella are actively bending slender organelles, performing functions such as motility, feeding and embryonic symmetry breaking. We review the mechanics of viscous-dominated microscale flow, including time-reversal symmetry, drag anisotropy of
