Probing the interaction forces of prostate cancer cells with collagen I and bone marrow derived stem cells on the single cell level. [PDF]

, 2013
Adhesion of metastasizing prostate carcinoma cells was quantified for two carcinoma model cell lines LNCaP (lymph node-specific) and PC3 (bone marrow-specific).

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Experimental Study on Mechanical Specific Energy Optimization in Axial–Torsional Coupled Impact Drilling

Applied Sciences
Axial–torsional coupled impact drilling (ATCID) technology represents a promising solution for overcoming the drilling challenges posed by conglomerate formations, which are characterized by strong heterogeneity, high abrasiveness, and poor drillability.

Application of Phanerochaete Chrysosporium on Biochemimechanical Pulping Process of Terentang Wood (Campnosperma Auriculata Hook.f) [PDF]

, 2016
Terentang wood (Campnosperma auriculata Hook.f) is relatively low in specific gravity (0.3), hence its utilization as pulp by chemi-mechanical is an alternative process.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Research on mechanical specific energy model and parameters optimization of deep coal seam drilling considering jet-screw interaction

Meikuang Anquan
The Linxing Block on the eastern margin of Ordos Basin contains abundant coalbed methane resources. However, drilling operations in this area face challenges such as low efficiency and high technical difficulty due to factors including deep burial depth ...

Finite element modelling of an energy–storing prosthetic foot during the stance phase of transtibial amputee gait [PDF]

, 2011
Energy-storing prosthetic feet are designed to store energy during mid-stance motion and to recover it during latestance motion. Gait analysis is the most commonly used method to characterize prosthetic foot behaviour during walking. In using this method,

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
