A model for simulating speckle-pattern evolution based on close to reality procedures used in spectral-domain OCT

, 2014
A robust model for simulating speckle pattern evolution in optical coherence tomography (OCT) depending on the OCT system parameters and tissue deformation is reported.

Integrated photonic circuit in silicon on insulator for fourier domain optical coherence tomography [PDF]

, 2010
Optical coherence tomography (OCT) is a medical imaging technology capable of producing high-resolution, cross-sectional images through inhomogeneous samples, such as biological tissue. It has been widely adopted in clinical ophthalmology and a number of

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

Population Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Hepatocytes derived from human induced pluripotent stem cells: Towards establishing an in vitro model for assessing population variability in hepatotoxicity testing

Current Research in Toxicology
Interindividual differences in response to chemicals have been typically addressed through the use of a 10-fold default “uncertainty” factor. It was only recently that in vitro models emerged to quantitatively assess interindividual variability in the ...

Towards contactless optical coherence elastography with acoustic tissue excitation

Current Directions in Biomedical Engineering, 2015
Elastography presents an interesting approach to complement image data with mechanical tissue properties. Typically, the tissue is excited by direct contact to a probe.

ShcD adaptor protein drives invasion of triple negative breast cancer cells by aberrant activation of EGFR signaling

Molecular Oncology, EarlyView.
We identified adaptor protein ShcD as upregulated in triple‐negative breast cancer and found its expression to be correlated with reduced patient survival and increased invasion in cell models. Using a proteomic screen, we identified novel ShcD binding partners involved in EGFR signaling pathways.

Trou maculaire post traumatique chez un enfant de six ans: documentation par OCT

The Pan African Medical Journal, 2014
Les trous maculaires post-traumatiques sont, chez l'enfant, la première cause de trou maculaire, contrairement à celles de l'adulte. La tomographie en cohérence optique permet désormais un suivi plus objectif de ces déchirures rétiniennes.

Diffusion of Latent Semantic Analysis as a Research Tool: A Social Network Analysis Approach [PDF]

, 2010
Latent Semantic Analysis (LSA) is a relatively new research tool with a wide range of applications in different fields ranging from discourse analysis to cognitive science, from information retrieval to machine learning and so on. In this paper, we chart
