New Perspectives on Semiconducting Conjugated Oligomers for Neuromodulation in Hydra vulgaris

open access: yesAdvanced Materials Interfaces, EarlyView.
Semiconducting organic compounds, thiophene‐based, modify the rhythmic electrical activity of the cnidarian Hydra vulgaris acting on specific neuronal circuits. The ETE‐S trimer also forms electronically conducting wires in the living tissues of the animal.

Computational models for generating microvascular structures: Investigations beyond medical imaging resolution

open access: yesWIREs Mechanisms of Disease, Volume 15, Issue 1, January/February 2023., 2023
Abstraction of the formation of new vascular connections through angiogenesis. Abstract Angiogenesis, arteriogenesis, and pruning are revascularization processes essential to our natural vascular development and adaptation, as well as central players in the onset and development of pathologies such as tumoral growth and stroke recovery.

Bilateral retinal detachment in a case of preeclampsia

open access: yesBiomolecules & Biomedicine, 2011
Serous retinal detachment is an unusual cause of visual loss in preeclampsia. We report the case of 24-years-old primipara with severe preeclampsia who developed bilateral serous retinal detachment a few hours after delivery.

Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

open access: yesAdvanced Optical Materials, EarlyView.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

Synthesis and Characterization of Photoswitchable Covalent Ligands for the β2‐Adrenoceptor

open access: yesAngewandte Chemie, EarlyView.
A structure‐based design of a covalent photoswitchable ligand for the β2‐adrenergic receptor, a therapeutically relevant GPCR, is described. This tool facilitates the modification of the intrinsic activity of the protein by light. Computational analysis of its mechanism of action suggests that the photoswitch takes place within the binding pocket ...

Segmentation of Retinal Low-Cost Optical Coherence Tomography Images using Deep Learning [PDF]

open access: yesarXiv, 2020
The treatment of age-related macular degeneration (AMD) requires continuous eye exams using optical coherence tomography (OCT). The need for treatment is determined by the presence or change of disease-specific OCT-based biomarkers. Therefore, the monitoring frequency has a significant influence on the success of AMD therapy.
