Efficacy of Acupoints Dual-Frequency Low-Level Laser Therapy on Knee Osteoarthritis.

Background: Knee osteoarthritis (OA) presented with knee pain and limitation of mobility is common, and it may become a chronic problem resulting in major loss of function, with related impaired activity of daily living. Current traditional therapy for knee OA includes pharmacological treatment and physiotherapy, but the efficacies are limited. An alternative noninvasive treatment low-level laser therapy (LLLT) applied to acupoints is still contradictory and the efficacy needs to be assessed.

Benefit and Risks of Aspirin in Addition to Ticagrelor in Acute Coronary Syndromes: A Post Hoc Analysis of the Randomized GLOBAL LEADERS Trial.

Importance: The role of aspirin as part of antiplatelet regimens in acute coronary syndromes (ACS) needs to be clarified in the context of newer potent P2Y12 antagonists.

Objective: To evaluate the benefit and risks of aspirin in addition to ticagrelor among patients with ACS beyond 1 month after percutaneous coronary intervention (PCI).

Design, Setting, And Participants: This is a nonprespecified, post hoc analysis of GLOBAL LEADERS, a randomized, open-label superiority trial comparing 2 antiplatelet treatment strategies after PCI.

Enhancement of light scattering and photoluminescence in electrospun polymer nanofibers.

Poly(methyl methacrylate) nanofibers with desired fiber diameters that ranged from 336 to 896 nm were electrospun as light scattering and propagation materials. The light scattering behavior of these samples as a function of the fiber diameter and fiber deposition thickness was examined by UV-vis spectrophotometry, which revealed the scattering bands in the absorption spectra. The scattering bands of these nanofibers were linearly proportional to the fiber diameter, which shows good agreement with a scattering model based on the Mie theory.
