Abstract

Background: Cirrhosis is the end‐stage of progressive fibrosis, in which oxidative stress and inflammation‐related pathways can modulate the cellular and tissue events involved in the pathogenesis of liver fibrosis. Dietary intake of antioxidants has been suggested to protect against oxidative damage and related clinical complications. The present study aimed to investigate the potential association of the dietary total antioxidant capacity (dTAC) with anthropometric, functional and biochemical markers, as well as the severity of the disease, in cirrhotic outpatients. Methods: Sixty‐two outpatients (38 men and 24 women) with a mean (SD) age of 59.1 (9.9) years were evaluated. Dietary TAC was estimated from a food frequency questionnaire. Aetiology and severity of liver cirrhosis, lifestyle characteristics, occurrence of comorbidities and oedema, and anthropometric, functional and biochemical markers were all assessed. Results: Cirrhotic outpatients with higher dTAC also had higher values of the hand‐grip strength (P = 0.029) and arm muscle area (P = 0.027). After adjusting by sex, age, smoking and alcohol intake, the addition of 1 mmol day−1 of dTAC contributed to increase 0.552 kg f−1 in hand‐grip strength (P < 0.05). The addition of one mmol day−1 of dTAC contributed to an arm muscle area increase 0.565 cm2 (P < 0.05) on average. Conclusions: The dTAC was positively associated with hand‐grip strength and arm muscle area in cirrhotic outpatients. The implications of the present study are important in clinical practice because a diet rich in antioxidants may be an ally in the control of excessive reactive oxygen species production in cirrhotic outpatients with repercussion on muscle mass and strength.

38. Capsulight: an innovative phototherapeutic strategy against severe gastric infections

Author

Morici, P., Battisti, A., Ghetti, F., Checcucci, G., and ANTONELLA SGARBOSSA

Abstract

Conventional antimicrobial strategies have become increasingly ineffective due to the emergence of antibiotic resistance among pathogenic bacteria. In order to overcome this problem, antimicrobial PhotoDynamic Therapy (PDT) is considered an alternative promising therapy. PDT has a broad spectrum of action and low mutagenic potential and is particularly effective when microorganisms present endogenous photosensitizing pigments. Helicobacter pylori (Hp), a pathogen notoriously responsible for severe gastric infections (chronic gastritis, peptic ulcer, MALT lymphoma and gastric adenocarcinoma), might be a suitable target of antimicrobial PDT as produces and accumulates the photosensitizers protoporphyrin IX and coproporphyrins. With the aim to design and develop an ingestible LED-based robotic pill for intragastric phototerapy so that irradiation can be performed in situ without the use of invasive endoscopic light, the action spectra for Hp photokilling will be determined. The photophysical properties of the Hp porphyrins will be studied. Hp culture samples will be irradiated at various wavelengths and intensities to determine the most efficient light conditions.

39. Photophysical characterization and fluorescence imaging of Helicobacter pylori endogenous porphyrins

Abstract

Helicobacter pylori (Hp) is among the most common infective agents in humans and is responsible for several gastric infections; moreover, its antibiotic resistance is raising new challenges. Antimicrobial photodynamic therapy (PDT) is a promising technique based on the use of non-toxic photosensitizers that, under the effect of a selected visible light, can generate cytotoxic reactive oxygen species; PDT is particularly effective when the target microorganism presents endogenous photosensitizers. It has been shown that the photosensitizers protoporphyrin IX and coproporphyrin I are endogenously produced in Hp, making it a suitable target for PDT. Aiming at the production of an ingestible LED-based robotic pill for intragastric PDT able to perform in situ irradiation without the use of endoscopic devices, the effectiveness of Hp photokilling in models has to be determined. We studied the distribution of porphyrins within bacteria suspensions and biofilms and adapted a protocol for porphyrins extraction from bacteria to characterize the spectroscopic features of the extracts.

N¨athke1 1Cell and Developmental Biology, School of Life Sciences, University of Dundee, Dundee, UK; 2School of Engineering, University of Glasgow, Glasgow, UK During tissue development and cancer progression, cells undergo mechanical changes and respond differently to physical cues from their environment. Usually measuring physical properties of biological samples relies on direct physical contact with the sample. We propose ultrasound as a versatile tool for imaging and also exerting forces on cells that does not require direct contact. Using a 40 MHz microultrasound transducer, we compared radiofrequency signals with optical images of 3D tissue structures. This revealed that the size of spherical structures correlates with the ultrasound RF signal. Ultrasound overestimates the size of hollow cysts by 33%, while no such offset was observed in solid spheroids. Early results also suggest that microultrasound can reveal mechanical properties. At lower frequencies (~ 4 MHz) and higher intensities, ultrasound can compress cell layers via acoustic radiation pressure and without the need to directly contact the sample. This allowed investigating how cells react to external mechanical forces. Developing this approach further will permit comparison of mechanical properties of tissue at different stages of cancer progression and increase our understanding of how mechanical forces direct
