Article Abstract
Aim: The purpose of the present study was to investigate if performance in a 30-s verbal semantic fluency task (i.e. animal naming) across five elderly aged groups (60-64; 65-69; 70-74; 75-79; 80-84 years) would be reflective of aging effect.
Methods: We analyzed differences in performance across 5-s phases and the moment of first word production in these five age groups.
Results: The following results were obtained: (i) with increasing age, the total number of words produced gradually declined (P < 0.001); (ii) there were significant differences in performance among the age groups in three phases (0-5, 6-10, 16-20 s) (P < 0.05); and (iii) the first word production within the first 5-s phase was significantly delayed in the 75-79 years and 80-84 years age groups compared with the rest of the age groups.
Conclusions: Performance in the initial 5-s phase might be sensitive to cognitive degeneration in normal older adults.

Single Cold Atmospheric Plasma Therapy May Improve the Treatment Outcome of Canine Otitis Externa With Secondary Infection.
Vet Dermatol
September 2025
Small Animal Practice, Alte Manufaktur, Viersen, Germany.
Background: Otitis externa (OE) with secondary bacterial or yeast infection is a common problem in small animal practice. Cold physical plasma (CPP) has been reported to have antimicrobial activity in vitro.
Hypothesis/objectives: This randomised, blinded, prospective study assessed the influence of additional CPP treatment on the recovery of canine OE with secondary infection.
Brain Activity During Electrical Stimulation of Visual-Motor Illusion with Enhanced Joint Motion Intensity.

Visual-motor illusion (VMI) is a kinesthetic illusion produced by viewing an image showing joint motion. VMI with enhanced joint movement intensity (power-VMI; P-VMI) is expected to activate a wide range of motor association brain regions, and when combined with electrical stimulation that activates the motor sensory cortex, further activation of brain activity can be expected. This study aimed to verify the effectiveness of VMI using functional near-infrared spectroscopy to confirm brain activity during combined P-VMI and electrical stimulation.

Discipline of Exercise and Sport Science, School of Health Sciences, Faculty of Medicine and Health, University of Sydney, Camperdown, NSW, Australia.
Purpose: This study examined the effects of cluster sets (CS) versus traditional sets (TRAD) on performance and perceptual responses during pneumatic chest press (CP) and leg press (LP). Exercise-specific differences and the influence of sex and strength were also explored.
Methods: Forty-seven recreationally resistance-trained young adults (23 male and 24 female) performed CP and LP at 70% 1-repetition maximum in either CS (4 × [2 × 5], 30-s intraset rest, 150 s between sets) or TRAD (4 × 10, 180-s rest between sets) in randomized order.
Removal and inactivation of human coronavirus surrogates from hard and soft surfaces using disinfectant wipes.
Appl Environ Microbiol

Disinfectant wipes are widely used to reduce microbial contamination on surfaces, yet there is limited information on how viruses are physically removed or chemically inactivated during wiping. This study aimed to address this gap by comparing the contributions of physical removal and chemical inactivation to overall disinfection efficacy. Glass and vinyl coupons were contaminated with SARS-CoV-2 surrogates, bovine coronavirus (BCoV), or human coronavirus OC43, at an initial titer of 5-6 log TCID/surface with 5% soil load.

Objectives: : This study aimed to assess the qualitative effects of locomotion training (LT) on articular cartilage using magnetic resonance imaging T1ρ mapping.
Methods: : Fifteen patients with early knee osteoarthritis participated in the study. They performed a series of exercises, including one-leg stands, squats, heel raises, and front lunges, on a daily basis for 12 weeks.
