Bezoars are foreign bodies impacted in the digestive tract resulting of their ingestion and accumulation, involving mainly the stomach. The most common types are phytobezoars, containing vegetables, fiber and seed, and the trichobezoar, made of hair. The present case is the description of a 25-year-old female with nonspecific dyspeptic symptoms associated to intestinal habit change. The diagnos...

background: human hair can be used as an inexpensive and accessible adsorbent to remove a variety of pollutants from air. although several studies have been done on removal of formaldehyde from wastewater by human hair, to date no study has investigated using hair to remove formaldehyde from air. therefore, the aim of this study was to remove formaldehyde from synthetic contaminated air by a re...

The avian auditory papilla contains two classes of sensory receptor, tall hair cells (THCs) and short hair cells (SHCs), the latter analogous to mammalian outer hair cells with large efferent but sparse afferent innervation. Little is known about the tuning, transduction, or electrical properties of SHCs. To address this problem, we made patch-clamp recordings from hair cells in an isolated chi...

A single multimode fiber (MMF) provides almost an ideal optical channel to constitute a hair-thin endoscope for minimally invasive biomedical imaging at depths in tissue, especially if the operation can be performed with one shot reflection mode, which, however, remains challenging date. In this work, we present single-shot wide-field reflectance by using MMF as illumination unit and probe simu...
