The human genome is the counterpart to the human exposome with respect to the gene × environment interaction that describes health state and outcome. The genome has already been sequenced and is in the process of being assessed for specific functionality; to similarly decode the exposome will require the measurement and interpretation of suites of biomarker compounds in biological media such as...
BACKGROUND Oro-cecal transit time (OCTT) is determined for clinical diagnostics of intestinal complaints and research purposes. Ingestion of a subsequent meal during the test period shortens the OCTT of a liquid test meal (glucose solution), as previously reported. This study was conducted to determine whether the same phenomenon occurs after ingestion of a solid test meal. MATERIALS AND METH...
Background/Overview Genetic testing of adults with suspected lactase insufficiency is proposed as an alternative to current diagnostic practices. Studies have demonstrated a tight correlation between a single nucleotide polymorphism (SNP) -13910 C > T upstream of the gene coding for the enzyme lactase and lactase insufficiency in persons of European ancestry. Currently, two indirect tests of la...
Breath tests (BT) represent a valid and non-invasive diagnostic tool in many gastroenterological disorders. Their wide diffusion is due to the low cost, simplicity and reproducibility and their common indications include diagnosis of carbohydrate malabsorption, Helicobacter pylori infection, small bowel bacterial overgrowth, gastric emptying time and orocaecal transit time. The review deals wit...
OBJECTIVES The objective of this study was to assess the outcome of antimicrobial susceptibility-guided therapies in Helicobacter pylori-infected individuals who had undergone unsuccessful prior eradication treatments. METHODS From October 2004 to December 2013, 481 H. pylori-positive patients with prior unsuccessful eradication treatments were administered susceptibility-guided salvage eradi...
objective: childhood infectious diseases are one of the most known environmental pathogenic causes of childhood asthma. the high prevalence of both helicobacter pylori infection and asthma in our country prompted us to assess anyprobable as- sociation between them in childhood. methods: this cross-sectional study recruited 196 children aged 6 to 12 years old comprising 98 asthmatic (case group)...
Chronic renal failure (CRF) is associated with a decrease in renal excretion of drugs, but its effects on the liver metabolism of xenobiotics are poorly defined. The objectives of this study were to determine the effects of CRF on hepatic cytochrome P450 (CYP450) and its repercussions on in vivo hepatic metabolism of drugs. Two groups of rats were studied: control paired-fed and CRF. CRF was in...
