Molecular signaling and mechanisms of low-level laser-induced gene expression in cells involved in orthodontic tooth movement

open access: yesJournal of the Formosan Medical Association
Background: The study aimed to observe molecular signaling, including reactive oxygen species (ROS) and mitochondrial membrane potential (ΔΨm), to evaluate the alteration of gene expression by low-level laser therapy (LLLT) and the correlation between ...

Contact Whiskers for Millimeter Wave Diodes [PDF]

open access: yes
Several techniques are investigated for making short conical tips on wires (whiskers) used for contacting millimeter-wave Schottky diodes. One procedure, using a phosphoric and chromic acid etching solution (PCE), is found to give good results on 12 ...

Low-level laser therapy enhances osteogenic differentiation of gingiva-derived stem cells in 2D and 3D cultures

open access: yesScientific Reports
Modulation of cellular activity by low-level laser therapy (LLLT) has been widely studied, particularly in regenerative medicine. This study examined the effects of LLLT on the viability, osteogenic differentiation, and mineralization of gingiva-derived ...

Does LLLT improve radiographic healing for dogs with cranial cruciate ligament rupture undergoing TPLO surgery?

open access: yesVeterinary Evidence
Question In canine patients undergoing tibial plateau levelling osteotomy (TPLO) surgery for unilateral cranial cruciate ligament rupture (CCLR), is LLLT (low-level laser therapy (less than 200 mw)) treatment effective at reducing time to radiographic ...
