OBJECTIVES To investigate the anti-Helicobacter pylori activity of 28 strains of Lactobacillus salivarius and 12 other lactobacilli, isolated from different sites and from different geographical regions. METHODS An in vitro agar plate diffusion assay was employed to assess the Lactobacillus anti-H. pylori activity. RESULTS Nine out of 28 L. salivarius(More)
Retinoids are important cellular, dietary factors that regulate differentiation and cellular growth. They serve as ligands for specific nuclear receptors, the retinoic acid receptors (RARs). Ligand-activated receptors regulate gene transcription through target retinoic acid-responsive elements (RAREs) found in promoter regions. We have investigated the(More)
The bacterial flagellum is a highly complex prokaryotic organelle. It is the motor that drives bacterial motility, and despite the large amount of energy required to make and operate flagella, motile organisms have a strong adaptive advantage. Flagellar biogenesis is both complex and highly coordinated and it typically involves at least three two-component(More)
Classical Hodgkin lymphoma (CHL), a neoplasm of abnormal B lymphocytes (Hodgkin-Reed-Sternberg (HRS) cells), has been described to have a typical pattern of clinical presentation and dissemination often involving functionally contiguous lymph nodes. Despite the progress made in understanding CHL pathophysiology, the factors that regulate the spread of(More)
Patient-centred care (PCC) is recommended in policy documents for chronic heart failure (CHF) service provision, yet it lacks an agreed definition. A systematic review was conducted to identify PCC interventions in CHF and to describe the PCC domains and outcomes. Medline, Embase, CINAHL, PsycINFO, ASSIA, the Cochrane database, clinicaltrials.gov, key(More)
Gastric epithelial cells (GECs) undergo apoptosis during H. pylori infection and phagocytes within the mucosa engulf these cells. The recognition and clearance of apoptotic cells is a multifactorial process, enhanced by the presence of various bridging molecules and opsonins which are abundant in serum. However, it is not clear how recognition or clearance(More)
BACKGROUND Helicobacter pylori is the causative agent for gastritis, and peptic and duodenal ulcers. The bacterium displays 5-6 polar sheathed flagella that are essential for colonisation and persistence in the gastric mucosa. The biochemistry and genetics of flagellar biogenesis in H. pylori has not been fully elucidated. Bioinformatics analysis suggested(More)
