A carbon-based material was synthesized using potato peels (BPP) and banana pseudo-stems (BPS), both of which were modified with manganese to produce BPP-Mn and BPS-Mn, respectively. These materials were assessed for their ability to activate peroxymonosulfate (PMS) in the presence of MnCO to degrade acetaminophen (ACE), an emerging water contaminant. The materials underwent characterization using spectroscopic, textural, and electrochemical techniques.

- This study explored how a mandibular advancement appliance (MAD) affects corticomotor excitability in patients with obstructive sleep apnea (OSA).
- Using a randomized, placebo-controlled design, 28 adults with mild or moderate OSA were tested to see how a 2-week use of MAD impacted muscle responses in the masseter and tongue.
- Results showed significant increases in both the masseter and tongue muscle activity after using the MAD, suggesting short-term use might enhance neuroplasticity in the brain pathways related to these muscles, which could improve understanding of OSA treatments.
Carbon nitrides can form coordination compounds or metallic oxides in the presence of transition metals, depending on the reaction conditions. By adjusting the pH to basic levels for mild synthesis with metals, composites like g-CN-M(OH) (where M represents metals) were obtained for nickel (II) and manganese (II), while copper (II) yielded coordination compounds such as Cu-g-CN. These materials underwent spectroscopic and electrochemical characterization, revealing their photocatalytic potential to generate superoxide anion radicals-a feature consistent across all metals.

Objectives: To evaluate the variability and accuracy to target force of a newly designed intraoral extension for a palpometer device (Palpeter, Sunstar Suisse) when compared to manual palpation, in addition to clinically assessing the mechanical sensitivity and referred sensations of the temporal tendon in healthy individuals.
Methods: Experiment 1: 12 individuals were asked to target on a scale 0.
Article Synopsis
- The study evaluates the accuracy and precision of forces generated during dynamic palpation of the temporomandibular joint using two methods: manual palpation and a palpometer, as per the DC/TMD protocol.
- Nineteen healthy adults participated, applying targeted forces and times with both methods, and results showed that the palpometer yielded significantly better accuracy and precision than manual palpation.
- Despite the improvements with the palpometer, participants struggled to adhere to the targeted palpation times, generally finishing faster than recommended.
