Exploring the protective role of metformin and dehydrozingerone in sodium fluoride-induced neurotoxicity: evidence from prenatal rat models.

This study is aimed at evaluating the neurotoxic effects of chronic exposure of sodium fluoride (NaF) in developmental stages in rat using prenatal models. NaF (100 ppm, orally) dosing via drinking water was given to pregnant rats in disease group. In the treatment groups, Metformin & Dehydrozingerone (DHZ) (200 mg/kg) were administered orally along with NaF, and the dosing was continued throughout the gestation and lactation periods to the pups until the end of experiment.

An environmental scan of equity-related measures for the certified nursing assistant dementia care workforce.

Introduction: Certified nursing assistants (CNAs) constitute the largest segment of the nursing home workforce, with over 50% of the dementia care workforce comprised of racial and ethnic minoritized individuals. Despite their critical role in dementia care, CNAs face significant inequities in terms of salary, treatment, and working conditions. To enhance equity and improve working conditions, valid and reliable measures are essential for nursing homes to assess their current environment, track progress, and refine strategies.

Outcomes of Radical Radiotherapy (RT) or Chemoradiotherapy (CRT) in Surgically Inoperable Advanced Oral Cavity Cancer: A Single Center Experience.

Background: Patients with locally advanced, surgically unresectable oral squamous cell cancers (SU-OSCC) are often treated with palliative intent. There is limited information on the outcomes of radical intent treatment with radiotherapy (RT) or chemoradiotherapy (CRT).

Methods: We retrospectively examined patients with Stage III/IV previously untreated SU-OSCC treated definitively from 2011 to 2021 in a single institution with RT or CRT with or without neoadjuvant chemotherapy (NACT).

Experimental and computational analysis of hybrid fiber metal laminates for vibration behavior in marine structural applications.

Structural advancements in underwater vehicle design necessitate lightweight materials, driving interest in Fiber Metal Laminates (FMLs), known for their high specific strength, stiffness, and corrosion resistance. This study investigates the vibration response of FMLs through combined experimental and numerical analyses, specifically evaluating the novel effects of layerwise acoustic impedance matching on vibration damping within the 0-500 Hz frequency range, which aligns with ocean current frequencies. Various FML stackup sequences were characterized through ASTM E756-05 compliant experiments and ANSYS Harmonic Response simulations.
