Comparison of graft uptake by underlay and overlay technique in myringoplasty.

Journal of Ayub Medical College, Abbottabad : JAMC, 2021
About 80% of tympanic membrane tears consequential of middle ear infections or trauma restore spontaneously. Myringoplasty is the procedure to fix the perforation which fails to heal. It is of two types; overlay and underlay techniques. In former technique graft is placed lateral to the fibrous sheet of the tympanic membrane while in underlay technique

Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy

Advanced Functional Materials, EarlyView.
In this study, we report producing spherical MXenes via fs laser fragmentation of Ti3C2 flakes in liquid medium. The nanoparticles demonstrated pronounced light absorption and high photothermal conversion efficiencies of 68% and 63% under heating with NIR‐I and NIR‐II lasers, respectively.
