CAVASS: a computer-assisted visualization and analysis software system - image processing aspects [PDF]

SPIE Proceedings, 2007
ABSTRACT The development of the concepts within 3DVIEWNIX and of the software system 3DVIEWNIX itself dates back to the 1970s. Since then, a series of software packages for Computer Assisted Visualization and Analysis (CAVA ) of images came out from our group, 3DVIEWNIX released in 1993, being the most recent, and all were distributed with source code.

Computer-assisted image processing to detect spores from the fungus Pandora neoaphidis

MethodsX, 2016
This contribution demonstrates an example of experimental automatic image analysis to detect spores prepared on microscope slides derived from trapping. The application is to monitor aerial spore counts of the entomopathogenic fungus Pandora neoaphidis which may serve as a biological control agent for aphids.

Age determination of eels in the French Mediterranean lagoons using classical methods and an image analysis system [PDF]

, 1990
Several methods are used for age determination of eels in the French mediterranean lagoons (observation of the whole otolith after clearing, grinding and polishing, dyeing, SEM and image analysis).

Digital mammography texture analysis by computer assisted image processing

2008 IEEE International Workshop on Imaging Systems and Techniques, 2008
We investigate the use of mammograms texture features in a clinical evaluation in mammography in order to assist in the classification of an image based on the breast tissue index. Breast tissue indices give the possibility to analyze images and determine the similarity of the images and evaluate the classification of the obtained image The measures of

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

FEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

S4ND: Single-Shot Single-Scale Lung Nodule Detection

, 2018
The state of the art lung nodule detection studies rely on computationally expensive multi-stage frameworks to detect nodules from CT scans. To address this computational challenge and provide better performance, in this paper we propose S4ND, a new deep

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

FEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

A stepwise emergence of evolution in the RNA world

FEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to
