Gastroesophageal reflux disease (GERD) is a complex disorder. Symptoms of heartburn can help find the disorder of GERD. pH testing is the mainstay of evaluation of symptoms, including 24-h and longer pH studies to detect pathologic acid exposure. The use of proton pump inhibitor (PPI) therapy for approved indications is helpful for both symptomatic relief and esophagitis healing in the majority of patients with abnormal acid exposure. PPI medications are safe in short- or long-term use. It is recommended not to maintain cirrhotic patients on PPI therapy without a meaningful indication. Dietary adjustment can provide benefit to some patients, but the data are mixed on how much benefit has been demonstrated from specific food avoidance. Reduction in weight improves reflux. Obesity has measurable effects on the esophageal acid exposure but fewer effects on the motility of the esophagus itself. Controlling weight and changing lifestyle can be helpful for improving GERD symptoms. For some patients in whom either the control of reflux with medications and lifestyle change is not sufficient or a hernia is contributing to symptom generation, surgical and endosurgical interventions can be considered to help manage reflux after a thorough workup with pH testing and manometry.

While the effect of time-of-day (morning versus evening) on hormones, lipids and lipolysis has been studied in relation to meals and exercise, there are no studies that have investigated the effects of time-of-day on ice bath induced hormone and lipidome responses. In this crossover-designed study, a group of six women and six men, 26 ± 5 years old, 176 ± 7 cm tall, weighing 75 ± 10 kg, and a BMI of 23 ± 2 kg/mhad an ice bath (8-12 °C for 5 min) both in the morning and evening on separate days. Absence from intense physical exercise, nutrient intake and meal order was standardized in the 24 h prior the ice baths to account for confounders such as diet or exercise.

Studies conducted so far have shown that nano- and microplastic may disturb the intestinal microenvironment by interacting with the intestinal epithelium and the gut microbiota. Depending on the research model used, the effect on the microbiome is different-an increase or decrease in selected taxa resulting in the development of dysbiosis. Dysbiosis may be associated with intestinal inflammation, development of mental disorders or diabetes.

Layer-by-Layer (LbL) self-assembly encapsulation is a promising technology for the protection and delivery of lactic acid bacteria. However, laboratory-scale encapsulation is often time-consuming, involves intensive protocols tailored for small-scale operations, requires substantial amounts of energy and water, and results in a low yield of encapsulated biomass. Scaling-up this process to a bench-bioreactor scale is not simply a matter of increasing culture volume as different key parameters (not particularly relevant at lab scale) become critical, including biomass production, the number of polymer layers, and the biomass-to-polymer mass ratio.

Most of the risk factors associated with chronic and complex diseases, such as cancer, stem from exogenous and endogenous exposures experienced throughout an individual's life, collectively known as the exposome. These exposures can modify DNA, which can subsequently lead to the somatic mutations found in all normal and tumor tissues. Understanding the precise origins of specific somatic mutations has been challenging due to multitude of DNA adducts (i.

Hexafluoropropylene oxide dimer acid (HFPO-DA), which belongs to the class of perfluoroalkyl ether carboxylic acid (PFECA), is a new alternative to perfluorooctanoic acid (PFOA). However, whether HFPO-DA is a safer alternative to PFOA in neonates remains unclear. In this study, we evaluated neonatal hepatic toxicity on postnatal days 9-10 by orally exposing pregnant CD-1 mice to 0.
