Mechanoadaptation via Myosin Cytoplasmic Redistribution Protects Circulating Tumor Cells From Shear‐induced Death During Hematogenous Dissemination

open access: yesAdvanced Science, EarlyView.
This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

Koncepcja krzemieniarstwa schyłkowego na przykładzie eneolitu Moraw

open access: yesPrzegląd Archeologiczny, 2012
The concept of Terminal Lithic Industries has been developed as a result of a century-long interest of Polish archaeologists in chipped stone materials from the turn of Stone and Bronze Ages.

Towards an understanding of Early Neolithic populations: a flint perspective from Bulgaria

open access: yesDocumenta Praehistorica, 2008
The evidence from the Bulgarian Early Neolithic chipped stone industry reveals coherent and diagnostic flint assemblages for the vast Karanovo I and II cultural area, characterized by high quality yellow-honey coloured flint, quite long and regular ...

A Soft Matrix Microenvironment Promotes Laterally Spreading Tumors via Oxidative Phosphorylation‐Dependent Cell Adhesion

open access: yesAdvanced Science, EarlyView.
Laterally spreading tumors (LSTs) are precancerous colorectal lesions characterized by a flat morphology. This study reveals a mechanochemical pathway through which a soft matrix microenvironment diminishes spatial constraints in intestinal adenomas. This process promotes deficiencies in tight junction proteins, mediated by the mechanoreceptor ADORA2B ...

Millimeter‐Scale Dual‐Opposing RNA‐Gradient Hydrogel for Interfacial Gene Silencing

open access: yesAdvanced Science, EarlyView.
A branched microfluidic platform enables the fabrication of millimeter‐scale hydrogels with dual‐opposing RNA‐gradients for precise spatial control of cell gene expression. This device allows for the generation of multiple constructs at once, offering potential for future engineering of complex tissue interfaces with improved physiological relevance ...

Chipped stone tools of the Aboriginal tribes east and north-east of Lake Eyre, South Australia

open access: yesPapers and Proceedings of the Royal Society of Tasmania
Many of the stones used for weaponry or as tools, were easy to source and therefore, any that were worn out were discarded as the supply for new ones was plentiful.

Archaeological Survey Investigations of Private Land within the boundaries of the proposed Lower Bois d’Arc Creek Reservoir Project, Fannin County, Texas [PDF]

open access: yes, 2016
At the request of a private landowner that has property within the boundaries of the proposed Lower Bois d’Arc Creek Reservoir in Fannin County, we completed volunteer archaeological survey investigations on a portion of this tract of private land on ...

A Dynamic 3D Human Liver Sinusoid Model for Mechanistic Interrogation of Fontan‐Associated Liver Disease

open access: yesAdvanced Science, EarlyView.
This study presents a perfusable 3D bioengineered liver sinusoid platform that integrates biofabrication, 3D cell culture, controlled hemodynamics, and multiparametric characterization to model Fontan‐associated liver disease. By decoupling pressure and hypoxia effects, the system reveals early mechanobiological and profibrotic responses under ...
