A Quarter Ellipsoidal Reflector Enhancing Fluorescence Collection Efficiency For Multiphoton Microscopes

IEEE Photonics Journal, 2016
In this paper, we present a fluorescence collection enhancement method for multiphoton microscopy by a quarter ellipsoidal reflector (QER). It is proven to be compatible with commercially available two-photon microscopes without significant customization.

Raman Spectroscopy Principles for in vivo Diagnostic by Ellipsoidal Reflectors

Electrical, Control and Communication Engineering, 2019
Abstract The paper presents the analysis of the functional abilities of measurement tools with ellipsoidal reflectors for Raman spectroscopy. The investigated structural scheme of the setup is intended for use in Raman spectroscopy in vivo by ellipsoidal reflectors. The setup can be used as a prototype for development of a device for non-

MANUFACTURING SPECIAL FEATURES OF ELLIPSOIDAL REFLECTOR FOR PHOTOMETERS

Bulletin of Kyiv Polytechnic Institute. Series Instrument Making, 2016
The improvement of method of making a mirror ellipsoid of revolution based on vertical-boring technology, which use the principles of trajectory copying, was proposed in this paper. The choice of material for making reflector was provided. The structural-functional scheme of a device for forming inner surface of ellipsoid and further finishing ...

CONTROL OF THE ELLIPSOIDAL REFLECTORS SHAPE FOR BIOMEDICAL PHOTOMETERS

Bulletin of Kyiv Polytechnic Institute. Series Instrument Making, 2017
A mirror coating technology by chemical-galvanic metallization of inner surface of ellipsoidal reflector produced by 3-D printing of ABS plastic is presented in the paper. Two ways of this technology realization were considerated. The first is by applying a conductive layer with graphite powder.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

FEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.
