Data from: Symmetry-breaking phase transitions in highly concentrated semen
New experimental evidence of self-motion of a confined active suspension is presented. Depositing fresh semen sample in an annular shaped microfluidic chip leads to a spontaneous vortex state of the fluid at sufficiently large sperm concentration. The rotation occurs unpredictably clockwise or counterclockwise and is robust and stable. Furthermore, for highly active and concentrated semen, richer dynamics can occur such as self-sustained or damped rotation oscillations. Experimental results obtained with systematic dilution provide a clear evidence of a phase transition towards collective motion associated with local alignment of spermatozoa akin to the Vicsek model. A macroscopic theory based on previously derived self-organized hydrodynamics models is adapted to this context and provides predictions consistent with the observed stationary motion.
Conditions for electronic hybridization between transition-metal dichalcogenide monolayers and physisorbed carbon-conjugated molecules
<p>We provide the numerical data for the projected unit cell band structures of the four TMDCs; for the hybrid systems, we include in- and output files of the geometry optimizations as well as the band structure calculations, together with the post-processed final band energies and spectral weights; for the isolated molecules, we provide the data files of relevant orbitals mapped to the Brillouin zone in conjunction with a python script for visualization</p>

The CXCR4 antagonist R54 targets epithelial-mesenchymal transition (EMT) in human ovarian cancer cells
<p><strong>Abstract</strong></p> <p><span>The axis CXCL12-CXCR4 is highly expressed in ovarian cancer where contributes to disease progression. Aim of the work was to evaluate the effect of the newly developed CXCR4 antagonist R54 on human ovarian cancer cells aggressiveness. CXCL12-CXCR4 axis was evaluated in human ovarian cancer cells through proliferation, migration and signaling CXCL12-dependents. Epithelial to mesenchymal transition (EMT)</span><span> </span><span>was analyzed through <em>E-CADHERIN</em>, <em>N-CADHERIN</em>, <em>VIMENTIN</em>, <em>SNAIL1</em> and <em>ΒETA-CATENIN</em> by qRT-PCR, immunofluorescence and immunoblotting.</span><span> </span><span>R54 inhibited ovarian cancer cells proliferation and migration CXCL12-induced. Moreover, R54 inhibited CXCL12 dependent pERK1/2 and pAKT and reversed the CXCL12 induced EMT in ovarian cancer cells. Targeting CXCR4 with the new antagonist R54 consistently reverted the mesenchymal transition in human ovarian cancer cells reducing migratory and chemoresistance features.</span></p>
Dutch Transitional Rapier
c. 1650 Dutch or English Transitional Rapier Oakeshott Collection Catalogue Number:OC 015 Mid 17th C. transitional rapier of a style popular in England and the Low countries. The blade is marked "Sahagvn" in the fuller, likely referencing Alonzo de Sahagun, the famous bladesmith of Toledo. The grip is bound in wire with turks heads top and bottom. The elegant hilt has a guard composed of two very fine pierced mesh plates. The holes are on average 2.5mm in size. A fluted pommel is attached to end of the knuckle bow via a screw. * Overall Length : 38.125 in | 968mm * Blade Length from front of guard: 31.125 in | 791mm * Blade Width (@ Guard): 0.92 in | 23.4mm * Grip Length : 3.06 in | 77.7mm * Shell Width (@ Widest): 3.36 in | 85.5mm * Center of Mass : 2.31 in | 58.7mm (from crossguard) * Weight: 1.4 lbs | 636.5 gr  [Support us on Patreon](https://www.patreon.com/oakeshott) [Follow us on Facebook](https://www.facebook.com/oakeshottinstitute) Source: Objaverse 1.0 / Sketchfab
