Background/aims: Previous studies have shown that psychological factors play a role in symptom perception among patients with gastroesophageal reflux disease. This report describes the first controlled study showing the effects of relaxation training on symptom reports and esophageal acid exposure in patients with reflux disease.
Methods: Twenty subjects with documented reflux disease were studied during psychologically neutral and stressful tasks, followed immediately by either a relaxation or attention-placebo control intervention.
Results: Stressful tasks, relative to neutral tasks, produced significant increases in blood pressure, subjective ratings of anxiety, and reports of reflux symptoms. Despite increased symptom reports, stressful tasks did not significantly increase objective measures of esophageal acid exposure. Subjects who received a relaxation intervention after the stressful task had significantly lower heart rate values and subjective ratings of anxiety compared with subjects who received the attention-placebo control intervention. Subjects who received relaxation training also had significantly lower reflux symptom ratings and total esophageal acid exposure than subjects who received the attention-placebo control intervention.
Conclusions: Relaxation may be a useful adjunct to traditional antireflux therapy in patients who experience increased symptoms during stress.

Background: The 2023 IPNA guidelines recommended a 12-h mycophenolic acid (MPA) area under the curve (AUC) estimation for managing pediatric nephrotic syndrome and MPA AUC > 50 mg * h/L for an optimal therapeutic response to mycophenolate mofetil (MMF). The IPNA guidelines endorsed two limited AUC formulae based on three-point MPA measurements to predict 12-h MPA AUC. The relative performance of these two limited AUC formulae has not been tested.

Dyslipidemia is a prominent pathological feature responsible for oxidative stress-induced cardiac damage. Due to their high antioxidant content, dietary compounds, such as aspalathin and sulforaphane, are increasingly explored for their cardioprotective effects against lipid-induced toxicity. Cultured H9c2 cardiomyoblasts, an in vitro model routinely used to assess the pharmacological effect of drugs, were pretreated with the dietary compounds, aspalathin (1 μM) and sulforaphane (10 μM) before exposure to palmitic acid (0.

Prenatal exposure to per- and polyfluoroalkyl substances (PFASs) has been linked to adverse fetal growth and development. However, most evidence was generated based on the singleton pregnancy studies, whereas potential impact on twin fetuses remains largely unknown. This study aimed to explore the associations of prenatal PFAS exposure with the growth and developmental differences within twin pairs by investigating 162 twin newborns and their mothers and determining 19 PFASs in maternal serum during the first, second, and third trimesters and cord serum of twins.

N-Nitrosamines are a class of compounds that includes the potent mutagenicity and carcinogenicity of many of its members and is distributed widely throughout the human environment. DNA alkylation by their diazonium ions formed metabolically acts as a molecular initiating event (MIE) that links molecular chemistry to mutagenicity. However, the regiochemistry for diazonium ions reacting with DNA bases is still under debate.

The detrimental effects of cadmium (Cd), a hazardous heavy metal, on fish have triggered global concerns. While the ecotoxicity of Cd on fish has been investigated, the impact of Cd on muscle quality and its correlation with the gut microbiota in fish remains scarce. To comprehensively uncover Cd effects based on preliminary muscle Cd deposition, relevant studies, and ecological Cd pollution data, we exposed Labeo rohita to Cd under concentrations of 0.
