Template assisted surface micro microstructuring of flowable dental composites and its effect on the microbial adhesion properties [PDF]

, 2016
Despite their various advantages, such as good esthetic properties, absence of mercury and adhesive bonding to teeth, modern dental composites still have some drawbacks, e.g., a relatively high rate of secondary caries on teeth filled with composite ...

All‐In‐One Iontronic Sensing Aligner for High‐Precision 3D Orthodontic Force Monitoring

Advanced Science, EarlyView.
A wireless, battery‐free orthodontic sensing system is developed by integrating a cross‐shaped iontronic sensor and an origami‐inspired NFC circuit into clear aligners. This all‐in‐one device enables real‐time, in vivo 3D force monitoring with high precision and long‐term stability, providing clinicians with quantitative biomechanical feedback to ...

High‐Density Flexible Neural Implants with Submicron Feedline Resolution

Advanced Electronic Materials, EarlyView.
Optimization of microfabrication methods using optical contact lithography (OCL) and electron beam lithography (EBL) enables the fabrication of 64‐channel, high‐density, parylene‐C‐based intracortical implants with submicron feedlines as narrow as 400 and 50 nm, respectively.

EXPERIMENTAL STUDY ON SOME CHARACTERISTICS OF DENTAL RESTORATION FILLINGS USED IN CORONARY THERAPEUTIC MANAGEMENT OF FIRST PERMANENT MOLAR

Romanian Journal of Oral Rehabilitation, 2015
Introduction Many modern materials used by modern medicine are in close contact or interact with tissues or body fluids, therefore their selection must take into consideration not only the physical and long-term stability but also biological compatibility. Modern coronal restorative materials such as composites, glass ionomer cements and compomers have

Diosgenin ameliorates silica‐induced tuberculosis in rats

Animal Models and Experimental Medicine, EarlyView.
Silicosis increases susceptibility to tuberculosis due to impaired macrophage function and oxidative stress. This study demonstrates that diosgenin, a steroidal saponin, significantly inhibits Mycobacterium smegmatis (IC₅₀ = 0.006 μg/mL), reduces lung fibrosis, and restores antioxidant enzyme levels (↑SOD, ↑CAT, ↓MDA) in silica‐exposed rats ...

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?

The Anatomical Record, EarlyView.
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...
