Impact and implications of mixed plaque class in automated characterization of complex atherosclerotic lesions

Yanan Niu

Atherosclerosis is a complex disease altering vasculature morphology, and subsequently flow, with progressive plaque formation, mural disruption, and lumen occlusion. Determination of clinically-relevant plaque components-particularly calcium, lipid, and f ...

Classification of Healthy and Cancer States of Colon Epithelial Tissues Using Opto-magnetic Imaging Spectroscopy

Marko Baros

Colorectal carcinoma (CRC) as a major health problem in industrialized countries is highly preventable and can be successfully treated in the early stages. However, incidence and mortality of CRC has increased over the last two decades. The reason could be ...

Correlation between podoplanin expression and extracapsular spread in squamous cell carcinoma of the oral cavity using subjective immunoreactivity scores and semiquantitative image analysis

Background. The correlation between podoplanin expression and extracapsular spread in head and neck squamous cell carcinoma (HNSCC) has never been reported. The purpose of this study was to assess the predictive value of podoplanin expression for this para ...

Combined CSL and p53 downregulation promotes cancer-associated fibroblast activation

Melody Swartz, Cathrin Brisken, Csaba Ferenc László

Stromal fibroblast senescence has been linked to ageing-associated cancer risk. However, density and proliferation of cancer-associated fibroblasts (CAFs) are frequently increased. Loss or downmodulation of the Notch effector CSL (also known as RBP-Jκ) in ...

Synthesis of C-linked Disaccharides and Analogues as Biomimetics of the TF Epitope

Maria Kolympadi

Glycoproteins and glycolipids are major components of the outer surface of mammalian cells. Their carbohydrate moieties, which are directed into the outer environment, serve as ligands for receptor proteins, such as lectins, pathogen proteins and antibodie ...

Endoscopic Fluorescence Imaging : Spectral Optimization and in vivo Characterization of Positive Sites by Magnifying Vascular Imaging

Blaise Lovisa

Since several decades, the physicians are able to access hollow organs with endoscopic methods, which serve both as diagnostic and surgical means in a wide range of disciplines of the modern medicine (e.g. urology, pneumology, gastroenterology). Unfortunat ...

Influence of emulsion composition on lubrication capacity and texture perception

Stefano Mischler

P>The role of fat content and type of surfactant for oral friction processes and texture perception of oil-in-water emulsions was assessed. Emulsions at 22% and 33% fat content containing either sodium caseinate or a sucrose ester as emulsifier were compar ...

Pharmacokinetics and pharmacodynamics of tetra(m-hydroxyphenyl)chlorin in the hamster cheek pouch tumor model: comparison with clinical measurements

Hubert van den Bergh, Georges Wagnières

The pharmacokinetics (PK) of the photosensitizer tetra(m-hydroxyphenyl)chlorin (mTHPC) was measured by optical fiber-based light-induced fluorescence spectroscopy (LIFS) in the normal and tumoral cheek pouch mucosa of 29 Golden Syrian hamsters with chem. i ...

Fluorescence pharmacokinetics of Lutetium Texaphyrin (PCI-0123, Lu-Tex) in the skin and in healthy and tumoral hamster cheek-pouch mucosa

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger

We have investigated the pharmacokinetics (PK) of Lutetium Texaphyrin (Lu-Tex), a second-generation photosensitizer, in the Syrian hamster cheek pouch early cancer model. Ten male hamsters, five with chem. induced early squamous cell cancer of the left che ...

Time-dependent biodistribution of tetra(m-hydroxyphenyl)chlorin and benzoporphyrin derivative monoacid ring A in the hamster model: comparative fluorescence microscopy study

Hubert van den Bergh, Georges Wagnières

The pharmacokinetics of the photosensitizer used play a key role in the understanding of the mechanism of photodynamic therapy-induced damage. Fluorescence microscopy was used to compare time-dependent biodistribution of tetra(m-hydroxyphenyl)chlorin (mTHP ...

Photodynamic therapy for early squamous cell carcinomas of the esophagus, bronchi, and mouth with m-tetra(hydroxyphenyl) chlorin

Hubert van den Bergh, Georges Wagnières

Objective: To clinically evaluate a new photosensitizer, m- tetra(hydroxyphenyl) chlorin (m-THPC), for the photodynamic therapy of early squamous cell carcinomas of the upper aerodigestive tract. Design: Phase 1 included evaluation of the innocuousness of ...

Photodynamic therapy of early squamous cell carcinoma with tetra(m-hydroxyphenyl)chlorin: optimal drug-light interval

Hubert van den Bergh, Georges Wagnières

The optimal drug-light interval for effective photodynamic therapy (PDT) of early squamous cell carcinomas was evaluated with tetra(m-hydroxyphenyl)chlorin (mTHPC) by means of two complementary modalities: irradiation tests and ex vivo fluorescence microsc ...

Clinical evaluation of a method for detecting superficial transitional cell carcinoma of the bladder by light-induced fluorescence of protoporphyrin IX following topical application of 5-aminolevulinic acid: Preliminary results

Hubert van den Bergh, Georges Wagnières

BACKGROUND AND OBJECTIVE: In bladder cancer, conventional white light endoscopic examination of the bladder does not provide adequate information about the presence of "flat" urothelial lesions such as carcinoma in situ. In the present investigation, we ex ...

In-vivo fluence rate effect in photodynamic therapy of early cancers with tetra(m-hydroxyphenyl)chlorin

Hubert van den Bergh, Georges Wagnières

Several parameters affect clin. trials in photodynamic therapy and influence the therapeutic outcome. Beside drug dose, light dose, drug-light interval and other variables, the fluence rate is a parameter that can influence the therapeutic results. In this ...
