Comparative chromatography of chloroplast pigment [PDF]

, 1969
Methods for isolation of low concentration pigments of the cocklebur species are described. The methods entail two step chromatography so that the different sorption properties of the various pigments in varying column parameters can be utilized ...

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

Molecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Digital Light Processing of 2D Lattice Composites for Tunable Self‐Sensing and Mechanical Performance

Advanced Engineering Materials, EarlyView., 2023
The study presents the mechanical and in situ sensing performance of digital light processing‐enabled 2D lattice nanocomposites under monotonic tensile and repeated cyclic loading, and provides guidelines for the design of architectures suitable for strain sensors and smart lightweight structures.

Strain Solitons in an Epitaxially Strained van der Waals-like Material [PDF]

Strain solitons are quasi-dislocations that form in van der Waals materials to relieve the energy associated with lattice or rotational mismatch in the crystal. Novel and unusual electronic properties of strain solitons have been both predicted and observed.

Survival of Staphylococcus aureus ST398 in the human nose after artificial inoculation. [PDF]

, 2012
There is evidence that MRSA ST398 of animal origin is only capable of temporarily occupying the human nose, and it is therefore, often considered a poor human colonizer.We inoculated 16 healthy human volunteers with a mixture of the human MSSA strain ...

An epidemic, toxin gene-variant strain of Clostridium difficile.

New England Journal of Medicine, 2005
BACKGROUND Recent reports suggest that the rate and severity of Clostridium difficile-associated disease in the United States are increasing and that the increase may be associated with the emergence of a new strain of C.

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

Molecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

Creep Characterization of Inconel 718 Lattice Metamaterials Manufactured by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView., 2023
Herein, the creep characteristics of additively manufactured Inconel 718 metamaterials are investigated. The creep behavior of metamaterials and the effects of microstructural defects are assessed, and the microstructure defects are accurately captured using Kachanov's creep damage model.

Strained Interpretations [PDF]

SSRN Electronic Journal, 2018
Judges often give statutes strained interpretations. What makes an interpretation strained? What, if anything, justifies a strained interpretation? Is there always a point past which an interpretation would be too strained, or are there some interpretations which judges are entitled to adopt, whatever a statute says?

Compressive and tensile axial strain reduced critical currents in Bi-2212 conductors [PDF]

, 1995
Mono and multifilamentary wires of BSCCO-2212 in Ag matrix are investigated in an axial strain experiment. The superconducting samples are soldered to a substrate that is bend in order to achieve a compressive or tensile axial strain. The I/sub c/-strain
