Article Synopsis
- The research investigates how different types of glial tumors in rats affect the attenuation coefficient of white matter in the brain, showing varied impacts based on tumor type and malignancy.
- Some tumors lead to a significant drop in this coefficient due to cell infiltration and damage to myelinated fibers, while others compress fibers without major destruction.
- The study also highlights the potential of using the attenuation coefficient, derived from OCT data, to identify late radiation damage in white matter, suggesting its usefulness for evaluating tissue health around tumors during surgeries.
Quantitative Assessment of Polarization and Elastic Properties of Endometrial Tissue for Precancer/Cancer Diagnostics Using Multimodal Optical Coherence Tomography.

: The most important phase in the endometrial pathologies diagnostics is the histological examination of tissue biopsies obtained under visual hysteroscopic control. However, the unclear visual diagnostics characteristics of subtle focal endometrial pathologies often lead to selection errors regarding suspicious endometrial lesions and to a subsequent false pathological diagnosis/underestimation of precancer or early-stage cancer. : In this study, we investigate the potential of Multimodal Optical Coherence Tomography (MM OCT) to verify suspicious endometrial lesion regions before biopsy collection.

- The study focuses on how plants respond to extreme conditions like microgravity and radiation, which is important for space exploration and improving plant resilience in outer space.
- Researchers created a 3D clinostat to replicate microgravity conditions and used proton irradiation to simulate space conditions, studying the effects on plant seeds from the Chernobyl exclusion zone.
- Results showed that one plant type was resilient to these conditions, while others experienced inhibited photosynthesis; findings and tools developed are available for further research in space biology.
While cryotherapy is one of the traditional ways to reduce postoperative complications in maxillofacial surgery, the cooling degree is not regulated in most cases and the achieved effect is not properly controlled. Therefore, to develop optimal cooling modes, we propose to study the buccal vascular response to cooling, which has not been previously shown. To evaluate the effect of cooling, we analyzed vessel networks using optical coherence tomography angiography (OCT-A).

Organotypic tissue slices preserve the spatial organization observed in vivo, making the tissue easily accessible for visualization and staining. This study aims to explore the use of fluorescence microscopy of physiologically compatible 3D tissue cultures to assess the effects of ionizing radiation.
