The gut wall provides an effective barrier against nanoparticle uptake

open access: yesBeilstein Journal of Nanotechnology, 2014
Background: The omnipresence of nanoparticles (NPs) in numerous goods has led to a constant risk of exposure and inadvertent uptake for humans. This situation calls for thorough investigation of the consequences of NP intake.

Efeito do etanol e do peróxido de hidrogênio intragástrico sobre a mucosa gástrica de rã (Rana catesbeiana, SHAW) Effect of intragastric ethanol and hydrogen peroxide in frog gastric mucosa (Rana catesbeiana, SHAW)

open access: yesBrazilian Archives of Biology and Technology, 1998
This work investigated the frog gastric mucosa response to hydrogen peroxide and ethanol induced injury. Acid and mucus secretion were estimated "in vitro" in control animals with intragastric absolute ethanol (1ml/30min.

How phagocytic cells kill bacteria: Lessons from a professional killer

open access: yesFEBS Open Bio, EarlyView.
How phagocytic cells ingest and kill bacteria has been studied for more than a century, but many questions remain unanswered. The study of the amoeba Dictyostelium discoideum brings new answers, and new questions. Professional phagocytic cells such as neutrophils and macrophages, as well as free‐living soil amoebae like Dictyostelium discoideum, employ

Recurrent Hypothermia and Autonomic Dysfunction Secondary to Shapiro Syndrome

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT A 44‐year‐old man presented with recurrent hypothermia, diaphoresis and hypertension. Extensive investigation for infectious, inflammatory, metabolic and endocrine aetiologies was negative. MR scan of the brain demonstrated no lesions but revealed callosal dysgenesis, consistent with Shapiro syndrome.

Computational modeling of cough-induced droplets and mucosal film dynamics in the upper airway for pulmonary disease classification

open access: yesFrontiers in Physiology
IntroductionCough-generated droplets are critical in the transmission and progression of respiratory diseases. This study investigates droplet formation and transport in the upper airway during a cough to improve understanding of their biomechanical ...

The Cervicovaginal Mucus Barrier [PDF]

open access: yesInternational Journal of Molecular Sciences, 2020
Preterm births are a global health priority that affects 15 million babies every year worldwide. There are no effective prognostic and therapeutic strategies relating to preterm delivery, but uterine infections appear to be a major cause. The vaginal epithelium is covered by the cervicovaginal mucus, which is essential to health because of its direct ...
