Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Digital holographic interference microscopy: physical method and algorithms of information processing

Вісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2022
Relevance. Interferometric methods for 3D visualization of micro-objects are highly non-invasive and non-contact. They can be used to obtain real-time information in the study of living and rapidly changing micro-objects.

Phase-modulation laser interference microscopy: an advance in cell imaging and dynamics study

Journal of Biomedical Optics, 2008
We describe how phase-modulation laser interference microscopy and wavelet analysis can be applied to noninvasive nonstained visualization and study of the structural and dynamical properties of living cells. We show how phase images of erythrocytes can reveal the difference between various erythrocyte forms and stages of hemolysis and how phase images

Suppression of lung adenocarcinoma migration through organelle alkalization by human lactoferrin – albumin fusion

FEBS Open Bio, EarlyView.
This paper reveals how human lactoferrin–albumin fusion (hLF‐HSA) potently suppresses lung adenocarcinoma cell migration. hLF‐HSA upregulates NHE7, leading to Golgi alkalization, disruption of the Golgi secretome, downregulation of MMP1, and reversal of EMT. These findings suggest a novel Golgi‐targeting strategy to suppress cancer cell migration.

A multi-modal microscope for integrated mapping of cellular forces and Brillouin scattering with high resolution

JPhys Photonics
Mechanical forces and stiffness play key roles in the health and development of cells and tissue, but despite the physical connection between these quantities, they cannot be monitored in parallel in most cases.

INVESTIGATION OF NEUTROPHILS UNDER TECHNOLOGICAL STRESS IN COWS BY METHODS OF LASER INTERFERENCE AND ELECTRON SCANNING MICROSCOPY

Siberian Journal of Life Sciences and Agriculture
Background.  Intensive milk production technology creates a number of factors that can put an animal into a state of technological stress. The effect of stress is reflected in nonspecific resistance, which represents the body's ability to resist the ...

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

FEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...

Interference and laser feedback optical microscopy

, 1995
This thesis concerns the development of simple, compact scanning optical microscopes which can obtain confocal and interference images. The effects of feeding the reflected signal back into the laser cavity of a confocal microscope are investigated and exploited.
