In Vivo Tissue Distribution of Microplastics and Systemic Metabolomic Alterations After Gastrointestinal Exposure.

Global plastic use has consistently increased over the past century with several different types of plastics now being produced. Much of these plastics end up in oceans or landfills leading to a substantial accumulation of plastics in the environment. Plastic debris slowly degrades into microplastics (MPs) that can ultimately be inhaled or ingested by both animals and humans.

Comparison of a micro-electro-mechanical system airflow sensor with the pneumotach in the forced oscillation technique.

Purpose: This study supports the use of thin-film micro-electro-mechanical system (MEMS) airflow sensors in the forced oscillation technique.

Materials And Methods: The study employed static testing using air flow standards and computer-controlled sound attenuations at 8 Hz. Human feasibility studies were conducted with a testing apparatus consisting of a pneumotach and thin-film MEMS air flow sensors in series.

Post-diarrhea chronic intestinal symptoms and irritable bowel syndrome in North American travelers to Mexico.

Objectives: Irritable bowel syndrome (IBS) has been reported to complicate bacterial diarrhea. Because of the frequency of international travel and the common occurrence of bacterial diarrhea, we studied the occurrence of chronic gastrointestinal complaints and post-diarrhea IBS in North U.S.

Modification of haemophiliac haemorrhage pain by transcutaneous electrical nerve stimulation.

Haemophiliacs suffer considerable pain when they bleed into their joints. This study investigated the use of transcutaneous electrical nerve stimulation (TENS) for relief of such pain. Thirty-six haemophiliac patients received either active or placebo TENS treatment.

Modification of induced ischaemic pain by transcutaneous electrical nerve stimulation.

Endurance to ischaemic pain was assessed in healthy subjects receiving either continuous or trains of transcutaneous electrical nerve stimulation (TENS) at different intensity levels. Control subjects received no stimulation. Self-reports of pain thresholds and pain tolerance levels were obtained, and on-going pain was assessed by means of two linear pain scales.
