Bacteria Inside Semiconductors as Potential Sensor Elements: Biochip Progress

Sensors, 2014
It was discovered at the beginning of this Century that living bacteria—and specifically the extremophile Pseudomonas syzgii—could be captured inside growing crystals of pure water-corroding semiconductors—specifically germanium—and thereby initiated ...

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

Metasurface Optics for Full-color Computational Imaging

, 2018
Conventional imaging systems comprise large and expensive optical components which successively mitigate aberrations. Metasurface optics offers a route to miniaturize imaging systems by replacing bulky components with flat and compact implementations ...

Inhibitor of DNA binding‐1 is a key regulator of cancer cell vasculogenic mimicry

Molecular Oncology, EarlyView.
Elevated expression of transcriptional regulator inhibitor of DNA binding 1 (ID1) promoted cancer cell‐mediated vasculogenic mimicry (VM) through regulation of pro‐angiogenic and pro‐cancerous genes (e.g. VE‐cadherin (CDH5), TIE2, MMP9, DKK1). Higher ID1 expression also increased metastases to the lung and the liver.

Automatic optical inspection of microscale defects on curved surfaces

Nihon Kikai Gakkai ronbunshu
In many areas of manufacturing, there is a growing need for imaging technology that non-destructively inspects the surface of products. However, detecting micro-defects on curved surfaces is challenging because the appropriate imaging conditions can vary

Three-Dimensional Chirped High-Contrast Grating Hollow-Core Waveguide

IEEE Photonics Journal, 2012
A 3-D chirped high-contrast grating hollow-core waveguide (HCG-HW) exhibits highly efficient 2-D (transverse and lateral) light confinement. Compared with step-index ones, laterally chirped HCG-HWs (graded index) can pronouncedly reduce the propagation ...

The Influence of Structure Parameters on Nanoantennas’ Optical Response

Chemosensors, 2020
Currently, huge opportunities for the inclusion of new optical devices in our lives have been appearing. There are evident and irrefutable examples for nanoantenna applications. They can be used to improve already developed devices or even be used as the

Linearizing nonlinear optics

, 2016
In the framework of linear optics, light fields do not interact with each other in a medium. Yet, when their field amplitude becomes comparable to the electron binding energies of matter, the nonlinear motion of these electrons emits new dipole radiation

Chemoresistome mapping in individual breast cancer patients unravels diversity in dynamic transcriptional adaptation

Molecular Oncology, EarlyView.
This study used longitudinal transcriptomics and gene‐pattern classification to uncover patient‐specific mechanisms of chemotherapy resistance in breast cancer. Findings reveal preexisting drug‐tolerant states in primary tumors and diverse gene rewiring patterns across patients, converging on a few dysregulated functional modules. Despite receiving the
