Is Microscopic Colitis Really Microscopic? [PDF]

open access: yesGut and Liver, 2015
Microscopic colitis (MC) is characterized by chronic watery diarrhea. MC comprises two entities: collagenous colitis (CC) and lymphocytic colitis (LC), which are separated by typical histopathological characteristics. The colonic mucosa appears endoscopically normal in general so it can be diagnosed only by colonic mucosal biopsies. But, macroscopic

A Comparative Study of Endoscopic versus Microscopic Cartilage Type I Tympanoplasty

open access: yesInternational Archives of Otorhinolaryngology, 2020
Introduction The use of endoscope is rapidly increasing in otological and neuro-otological surgery in the last 2 decades. Middle ear surgeries, including tympanoplasty, have increasingly utilized endoscopes as an adjunct to or as a replacement for the ...

Osculating Circle with Microscopes Within Microscopes [PDF]

open access: yesFoundations of Science, 2012
Classically, an osculating circle at a point of a planar curve is introduced technically, often with formula giving its radius and the coordinates of its center. In this note, we propose a new and intuitive definition of this concept: among all the circles which have, on the considered point, the same tangent as the studied curve and thus seem equal to

Coaxial Atomic Force Microscope Tweezers [PDF]

open access: yes, 2010
We demonstrate coaxial atomic force microscope (AFM) tweezers that can trap and place small objects using dielectrophoresis (DEP). An attractive force is generated at the tip of a coaxial AFM probe by applying a radio frequency voltage between the center

Design of a scanning tunneling microscope for electrochemical applications [PDF]

open access: yes, 1988
A design for a scanning tunneling microscope that is well suited for electrochemical investigations is presented. The construction of the microscope ensures that only the tunneling tip and the sample participate in electrochemical reactions.

Partial pulp necrosis caused by excessive orthodontic force

open access: yesRestorative Dentistry & Endodontics, 2011
As the dental pulp is encased with a rigid, noncompliant shell, changes in pulpal blood flow or vascular tissue pressure can have serious implication for the health of pulp.
