A fatty-acid based probe for near-infrared fluorescence guided surgery of glioblastoma

High-grade gliomas (HGG) are the most common and most aggressive primary tumors of the brain. Despite recent advances in neuro-oncology survival of these tumors remains around 12-15 months. The first-line of treatment is surgical resection. However, due to ...

A bioluminescent-based probe for in vivo non-invasive monitoring of nicotinamide riboside uptake reveals a link between metastasis and NAD plus metabolism

Elena Goun, Pavlo Khodakivskyi, Arkadiy Bazhin, Aleksey Yevtodiyenko, Tamara Maric, Georgy Mikhaylov

Nicotinamide riboside (NR) is a form of vitamin B3 and is one of the most studied compounds for the restoration of cellular NAD+ levels demonstrating clinical potential in many metabolic and age-related disorders. Despite its wide commercial availability a ...

Noninvasive imaging and quantification of bile salt hydrolase activity: From bacteria to humans

Elena Goun, Pavlo Khodakivskyi, Arkadiy Bazhin, Aleksey Yevtodiyenko

The microbiome-produced enzyme bile salt hydrolase (BSH) plays a central role in human health, but its function remains unclear due to the lack of suitable methods for measuring its activity. Here, we have developed a novel optical tool based on ultrasensi ...

Bioluminescent compositions and uses thereof

Elena Goun, Pavlo Khodakivskyi, Hacer Karatas, Aleksey Yevtodiyenko

Compositions and methods for non-invasively monitoring the intracellular processing of a biomolecule are provided. The compositions have a novel thio-luciferin moiety which can be conjugated to the biomolecule directly or via a linker such as disulfide bon ...

Portable bioluminescent platform for in vivo monitoring of biological processes in non-transgenic animals

Aurélien Godinat, Elena Goun, Pavlo Khodakivskyi, Arkadiy Bazhin, Aleksey Yevtodiyenko, Ghyslain Martial Alain Budin, Tamara Maric

Bioluminescent imaging (BLI) is one of the most powerful and widely used preclinical imaging modalities. However, the current technology relies on the use of transgenic luciferase-expressing cells and animals and therefore can only be applied to a limited ...

Synthesis and chemical transformations of diazolyl alpha,alpha-difluoroacetates

Pavlo Khodakivskyi

Optimized protocols for the synthesis of diazolyl alpha,alpha-difluoroacetates via deoxofluorination of the corresponding glyoxylates with Morph-DAST are described. The method allowed the preparation of the title fluoridated building blocks in 73-96 % yiel ...

Cell-specific image-guided transcriptomics identifies complex injuries caused by ischemic acute kidney injury in mice

Elena Goun, Pavlo Khodakivskyi

The kidney's inherent complexity has made identifying cell-specific pathways challenging, particularly when temporally associating them with the dynamic pathophysiology of acute kidney injury (AKI). Here, we combine renal cell-specific luciferase reporter ...

Bioluminescent-based imaging and quantification of glucose uptake in vivo

Riccardo Sinisi, Elena Goun, Pavlo Khodakivskyi, Arkadiy Bazhin, Aleksey Yevtodiyenko, Tamara Maric, Georgy Mikhaylov

Glucose is a major source of energy for most living organisms, and its aberrant uptake is linked to many pathological conditions. However, our understanding of disease-associated glucose flux is limited owing to the lack of robust tools. To date, positron- ...

Preclinical Evaluation of Photoacoustic Imaging as a Novel Noninvasive Approach to Detect an Orthopaedic Implant Infection

Riccardo Sinisi, Pavlo Khodakivskyi, Ghyslain Martial Alain Budin

Introduction: Diagnosing-prosthetic joint infection (PJI) poses significant challenges, and current modalities are fraught with low sensitivity and/or potential morbidity. Photoacoustic imaging (PAI) is a novel ultrasound-based modality with potential for ...
