Adult multilocular cystic nephroma: Report of six cases with clinical, radio-pathologic correlation and review of literature

open access: yesUrology Annals, 2013
Background: Cystic renal neoplasms of the kidney can be benign or malignant. Multicystic nephroma (MCN) represents a rare benign cystic lesion of the kidney, which usually presents as a unilateral multicystic renal mass without solid elements.

Image querying by image professionals [PDF]

open access: yesProceedings of the American Society for Information Science and Technology, 2003
AbstractThis paper reports the analysis of search logs from a commercial image provider over a one‐month period and discusses the results in relation to previous findings. The study analyzes image searches, image queries composing the search, user search modification strategies, results returned, and user browsing of results.

Heralded phase-contrast imaging using an orbital angular momentum phase-filter [PDF]

open access: yes, 2016
We utilise the position and orbital angular momentum (OAM) correlations between the signal and idler photons generated in the down-conversion process to obtain ghost images of a phase object.

Putting a Finishing Touch on GECIs

open access: yesFrontiers in Molecular Neuroscience, 2014
More than a decade ago genetically encoded calcium indicators (GECIs) entered the stage as new promising tools to image calcium dynamics and neuronal activity in living tissues and designated cell types in vivo.

Flat lens without optical axis: Theory of imaging

open access: yes, 2005
We derive a general theory for imaging by a flat lens without optical axis. We show that the condition for imaging requires a material having elliptic dispersion relations with negative group refraction, equivalent to an effective anisotropic refractive ...

Resolution limits of quantum ghost imaging [PDF]

open access: yes, 2018
Quantum ghost imaging uses photon pairs produced from parametric downconversion to enable an alternative method of image acquisition. Information from either one of the photons does not yield an image, but an image can be obtained by harnessing the ...

ERBIN limits epithelial cell plasticity via suppression of TGF‐β signaling

open access: yesFEBS Letters, EarlyView.
In breast and lung cancer patients, low ERBIN expression correlates with poor clinical outcomes. Here, we show that ERBIN inhibits TGF‐β‐induced epithelial‐to‐mesenchymal transition in NMuMG breast and A549 lung adenocarcinoma cell lines. ERBIN suppresses TGF‐β/SMAD signaling and reduces TGF‐β‐induced ERK phosphorylation.

3rd TPCF Preclinical Symposium Imaging(TPIS 2020)

open access: yesFrontiers in Biomedical Technologies, 2020
The path of discovering/designing a molecule to developing a novel drug could take up to an average of 12 years and costs around $1 billion (USD). Preclinical phase is a major step on this path and is the part where scientists perform additional studies ...
