Older adults exhibit lesser smoothness despite increased caution than younger adults when navigating turns during walking.

Straight line walking currently dominates research into mechanisms associated with walking-related instability; however, the dynamics of everyday walking behavior are far more complex. The figure-8 walk test (F8W) is a clinically-feasible activity that focuses on turning mobility and provides a convenient and relevant task for understanding age-related differences in walking beyond our present knowledge of steady-state behavior. Our purpose was to investigate the effects of age (n = 30 older versus n = 31 younger adults) on path characteristics and the "smoothness" of turning mobility - herein measured via normalized center of mass jerk - during the F8W.

Humic acid from vermicompost effectively regulates the redox status and mitigates the progression of experimental periodontitis.

The progression of periodontal disease (PD) involves the action of oxidative stress mediators. Antioxidant agents may potentially attenuate the development of this condition. Thus, we aimed to evaluate the effects of different doses of humic acid (HA), extracted from biomass vermicomposting, on redox status and parameters related to PD progression in rats.

Humic Acid Derived from Vermicompost Inhibits Alveolar Bone Degradation and Protects Against Renal Injury in an Experimental Model of Periodontitis.

Periodontal disease (PD) leads to the destruction of supportive tissues through an inflammatory response induced by biofilm accumulation. This low-grade systemic inflammation from PD increases the risk of comorbidities. Among potential therapeutic agents for PD, humic acids (HAs) are notable for their anti-inflammatory and immunomodulatory properties.
