Raman imaging of haem metabolism in situ in macrophages and Kupffer cells

12-Jun-2018 | Jakub Dybas; Marek Grosicki; Malgorzata Baranska; Katarzyna Maria Marzec, Analyst, 2018

Herein, we provide the Raman imaging results for different stages of erythrophagocytosis of senescent red blood cells executed by isolated murine primary Kupffer cells and murine macrophage cell line (RAW 264.7). Images were recorded with the use of 488 and 532 nm excitation lines. The use of ...

The alkyne-tag Raman imaging of coronatine, a plant pathogen virulence factor, in Commelina communis and its possible mode of action

27-May-2018 | Minoru Ueda; Kengo Hayashi; Syusuke Egoshi; Yasuhiro Ishimaru; Yousuke Takaoka; Hiroyuki Yamakoshi; Kosuke Dodo; Mik ..., Organic & Biomolecular Chemistry, 2018

We previously reported that coronatine, a virulence factor of plant bacteria, facilitates bacterial infection through an ER (endoplasmic reticulum)-mediated, non-canonical mechanism in the model dicot plant, Arabidopsis thaliana. Here, we report that this same ER-mechanism is ubiquitous among ...

Intracellular investigation on the differential effects of 4 polyphenols on MCF-7 breast cancer cells by Raman imaging

11-Jan-2018 | Alix Mignolet; Bayden Robert Wood; Erik Goormaghtigh, Analyst, 2018

The past decades have seen significant interest in the study of polyphenolic compounds as potential therapeutic agents in medicine because they display a vast array of cellular effects beneficial to treat or manage a plethora of chronic diseases including inflammatory diseases, cardiovascular ...

Two‐frequency CARS imaging by switching fiber laser excitation

11-Jan-2018 | Eric C. Rentchler, Ruxin Xie, Rongqing Hui, Carey K. Johnson, Microscopy Research and Technique, 2018

Abstract To fully exploit the power of coherent Raman imaging, techniques are needed to image more than one vibrational frequency simultaneously. We describe a method for switching between two vibrational frequencies based on a single fiber‐laser source. Stokes pulses were generated by soliton ...

Histological coherent Raman imaging: a prognostic review

30-Dec-2017 | Marcus T. Cicerone; Charles H. Camp, Analyst, 2017

Histopathology plays a central role in diagnosis of many diseases including solid cancers. Efforts are underway to transform this subjective art to an objective and quantitative science. Coherent Raman imaging (CRI), a label-free imaging modality with sub-cellular spatial resolution and ...

Development of a label-free Raman imaging technique for differentiation of malaria parasite infected from non-infected tissue

29-Dec-2017 | Laura Frame; James Brewer; Rebecca Lee; Karen Faulds; Duncan Graham, Analyst, 2017

During malarial infection, the host uses the spleen to clear the malaria parasites, however, the parasites have evolved the ability to bind to endothelial receptors in blood vessels of tissues to avoid removal, known as sequestration, and this is largely responsible for the symptoms and severity ...

Insights into the Evolution of Carbonate‐bearing Kaolin during Sintering revealed by in situ Hyperspectral Raman Imaging

05-Sep-2017 | Kerstin Stange, Christoph Lenting, Thorsten Geisler, Journal of the American Ceramic Society, 2017

Abstract Sintering reactions of clay bodies have previously been studied by numerous experiments that involve quenching of the sintered ceramic bodies to room temperature and analyzing the reaction product by different analytical techniques. In this study, green bodies containing quartz, ...

Stimulated Raman Imaging Reveals Aberrant Lipogenesis as a Metabolic Marker for Azole-Resistant Candida albicans

30-Aug-2017 | Caroline W. Karanja; Weili Hong; Waleed Younis; Hassan E. Eldesouky; Mohamed N. Seleem; Ji-Xin Cheng, Analytical Chemistry, 2017

Candida albicans is the single most prevalent cause of fungal bloodstream infections worldwide causing significant mortality as high as 50 percent. This high mortality rate is, in part, due to the inability to initiate an effective antifungal therapy early in the disease process. Mortality rates ...

Conjugated Polymer with Intrinsic Alkyne Units for Synergetically Enhanced Raman Imaging in Living Cells

29-Aug-2017 | Shu Wang, Angewandte Chemie International Edition, 2017

Development of Raman‐active materials with enhanced and distinctive Raman vibrations in the Raman‐silent region (1800‐2800 cm‐1) is highly required for specific molecular imaging of living cells with high spatial resolution. Herein, water‐soluble cationic conjugated polymers (CCPs), ...
