Figure 4 from “Cytoskeletal disorganization underlies PABPN1-mediated myogenic disability” by Cyriel Sebastiaan Olie et al. Disrupted cytoskeletal spatial organization in shPAB human muscle cell cultures. A Representative images of control and shPAB human muscle cell cultures, stained with antibodies to tubulin and actin, and the actin filaments were visualized with actin-GFP. B Tubulin staining in control and shPAB myoblast cell cultures after DMSO, 100 nM nocodazole or 25 nM paclitaxel treatment for 2 h. Scale bar is 25 µm. C Measurements of cell-mechanics properties in control and shPAB cells using the Brillouin Light Scattering Microscopy (Ci) or the Atomic Force Microscopy (Cii). Measurements were carried out in myoblasts; every dot represents the median from 1000 measurements in a cell. Cell stiffness is measured by GHz, and the young modulus reports the cell surface tension. Averages and standard deviations are from N = 15 cells. Statistical significance was calculated with the student’s t-test. NANOSENSORS uniqprobe qp-BioAC ( CB3 ) AFM probes were used in the quantitative imaging of cell-mechanics properties where a force curve is applied at each point.

Muscle wasting is connected with changes in various cellular mechanisms that influence protein homeostasis, transcription, protein acetylation and different metabolic pathways. * Scientific studies have… Read More »Cytoskeletal disorganization underlies PABPN1-mediated myogenic disability

Macroscopic manifestation of domain-wall magnetism and magnetoelectric effect in a Néel-type skyrmion host

Supplementary Figure 1 a – d from “Macroscopic manifestation of domain-wall magnetism and magnetoelectric effect in a Néel-type skyrmion host” by K. Geirhos et al: Typical ferroelectric do-main pattern observed on the (001) cleaved GaV4Se8 crystal surface atT=10 K. a, The topography is characterized by stripes roughly parallel to the [110] axis and folds parallel to the [010] axis. The latter originate in the differently oriented distortion of the ferroelastic domains. The color scale corresponds to the z-displacement of the tip. b ,In the dissipation channel of the nc-AFM every second domain appears bright. For the non-magnetic tip the dissipation originates from electric interactions. The dissipated power is indicated by the color scale. Please have a look at the full article to view the full supplementary figure. NANOSENSORS Platinum Silicide PtSi-FM AFM probes were used for the imaging.

The transferred average strain εave and corresponding magnetic domain evolution processes in the d ~ 350 nm a [Pt/Co/Ta]12 and b [Pt/Co/Ta]8 nano-dots in a cycle of E ranging from +10 to −10 kV cm−1. Positive εave (red dots) represents tensile strain while negative εave (blue dots) represents compressive strain. μ0H represents the external magnetic field except that from the MFM tip and here μ0H is equal to be 0 mT. The inset of b illustrates the spin texture of the magnetic domain that is encompassed by the red box. The stripe domain enclosed by the black box shows the initial state of the magnetic domain evolution path. The gray dots represent the corresponding electric field for the MFM images. The MFM contrast represents the MFM tip resonant frequency shift (Δf). The scale bar represents 250 nm. NANOSENSORS™ PPP-LM-MFMR low moment magnetic AFM probes were used
