Melatonin plays several important physiological functions in mammals, such as immune enhancement and regulation of dark-light signal transduction. Melatonin is also known to be an endogenous free radical scavenger and an efficient antioxidant. It detoxifies a variety of free radicals and reactive oxygen intermediates, including the hydroxyl radical, singlet oxygen and nitric oxide. These radica...
AIM To evaluate the association between virulence factor status and antibiotic resistance in Helicobacter pylori (H. pylori)-infected patients in Ireland. METHODS DNA was extracted from antral and corpus biopsies obtained from 165 H. pylori-infected patients. Genotyping for clarithromycin and fluoroquinolone-mediating mutations was performed using the Genotype HelicoDR assay. cagA and vacA ge...
INTRODUCTION Non-invasive assessment of steatosis and fibrosis is of growing relevance in non-alcoholic fatty liver disease (NAFLD). 1H-Magnetic resonance spectroscopy (1H-MRS) and the ultrasound-based controlled attenuation parameter (CAP) correlate with biopsy proven steatosis, but have not been correlated with each other so far. We therefore performed a head-to-head comparison between both m...
A novel radio frequency sensor technology is presented for continuous monitoring of the radio frequency spectrum with large instantaneous bandwidth that can perform spectral analysis and direction finding simultaneously. The photonic receiver technology relies on a spatial spectral (S2) holographic crystal recording device that is an extreme bandwidth analyzer and correlator (EBAC). The S2 EBAC...
