5c, right), in accordance with our callose detection in longitudinal cell walls (Fig. 3d,e and Extended Data Fig. 8a,b). The callose layer around the endosperm of muskmelon seeds has been previously reported to show properties of a semi-permeable layer58. If callose is mostly deposited ...
The Metaphor of the “Underground” and the Allegory of the CaveThe titleNotes from Undergroundhas a clear explanation within the text: the narrator, the Underground Man, has lived in a literal underground dwelling for over forty years. However, a deeper metaphorical layer emerges in Part One, ...
For compact globular proteins, there will be three distinct “electroviscous” contributions (Shaw, 1980; Dickinson, 1992): one from the resistance of the diffuse double (electrostatic) layer surrounding the protein—the “primary” effect; another from repulsion between the double layers of different...
The debate surrounding the relative contribution of genetic and environmental influences on the cranial vault has a long history, starting with the observation by Boas in the early 20th century10 that head dimensions can change in a single generation in response to environmental conditions. Formal ...
A tomography profile of cellular and intracellular stiffness was created by probing over a range of depths below the cell surface with an AFM nanoneedle. Differences between the softer external layer and the more rigid internal structure of corneocytes were revealed. The technique is capable of ...
in the leptomeningeal cell layer surrounding arterioles [55,56]. Even though our assumptions do not exactly match these findings, the path of least resistance for the flow of CSF seems to be through the SAS and around penetrating arterioles [52,53,54,55,56], which was captured in our ...
The corrosive cell with chloride ions has a significant effect on the process of cable corrosion, but the corrosion of corroded cells without chloride ions has little effect on the corrosion rate of the wire, which indicates that reducing the concentration of chloride ions in the surrounding ...
Surrounding the nucleic acid, their capsid is a hollow cylinder with a helical structure. An example of a helical virus that is a rigid rod is the tobacco mosaic virus (1)Helical viruses The capsid of most polyhedral viruses is in the shape of a regular polyhedron with 20 triangular faces ...
systematically probing all SATB1-dependent chromatin loops in the T cell nucleus. A number of datasets combined with unbiased analytical approaches indicate the presence of a functional organizational layer built upon a general chromatin scaffold dependent on conventional genome organizers, such as CTCF,...
