Probiotic Gastrointestinal Transit and Colonization After Oral Administration: A Long Journey
Frontiers in Cellular and Infection Microbiology, 2021 Orally administered probiotics encounter various challenges on their journey through the mouth, stomach, intestine and colon. The health benefits of probiotics are diminished mainly due to the substantial reduction of viable probiotic bacteria under the ...

Colon Shape Estimation Method for Colonoscope Tracking using Recurrent Neural Networks [PDF]
Published in Proceedings of MICCAI 2018, LNCS 11073, pp 176-184, 2020 We propose an estimation method using a recurrent neural network (RNN) of the colon's shape where deformation was occurred by a colonoscope insertion. Colonoscope tracking or a navigation system that navigates physician to polyp positions is needed to reduce such complications as colon perforation. Previous tracking methods caused large tracking errors

Influence of Immune Status on the Airborne Colonization of Piglets with Methicillin-Resistant Staphylococcus aureus (MRSA) Clonal Complex (CC) 398 [PDF]
, 2020 Colonized vertebrates including humans and pigs are to date the main reservoirs of livestock-associated Methicillin-resistant Staphylococcus aureus (LA-MRSA). Currently, the mechanisms underlying colonization of pigs are not fully understood.
