The thermo-physiological and tactile properties of socks were analysed by using hybrid yarns which were made by Polyethylene (PE) fibre with different fibres in variable ratios, using full-factorial experimental design. Socks samples were designed using hybrid yarns made with three blend ratios of polyethylene filament with cotton (Co), polyester (PET), polypropylene (PP), modal (Mo) and viscose (Vis) spun yarns. Statistical analysis was carried out according to response surface regression analysis (RSM). Among various analytical tools, RSM is adopted for prediction of multiple responses and response optimizer (RO) was used to optimize the thermo-physiological and tactile comfort i.e. softness and smoothness properties of socks by using the desirability function approach. It was inferred that the combination of cotton with polyethylene was most influencing for thermal conductivity and softness properties. Experimental validation confirmed that predicted variables can be used to design knitted socks fabric with desired thermo-physiological and tactile comfort properties.

The Sculptor is an innovative surgical instrument designed to improve precision, reproducibility, and surgeon comfort in high-definition (HD) liposculpture. Traditional liposculpture techniques rely heavily on the surgeon's manual and tactile skills, introducing potential variability in outcomes and contour deformities. Held in the surgeon's nondominant hand, the Sculptor guides the cannula for controlled fat removal.

A key strategy for pain management in dermatologic procedures is the use of local anesthesia, yet the injection itself often causes significant discomfort. This article explores evidence-based strategies to minimize pain during anesthetic administration in office-based dermatologic settings. Techniques discussed include buffering and warming lidocaine, selecting the optimal needle gauge, orienting the bevel properly, as well as adopting advanced injection methods such as subdermal bleb formation and parallel needle insertion.

Self-powered sensing technologies have sparked a revolution in electric devices. Furthermore, ultrathin characteristics are highly desirable for on-skin and wearable devices to achieve superior conformability on complex 3-dimensional surfaces, which facilitates improved wearing comfort and detection accuracy. However, developing self-powered sensors with ultrathin and conformal features without complicated fabrication processes remains a formidable challenge.

Background: The aging process involves many physiological changes that can significantly affect postural balance and stability. This study examines the effects of varying the height of protruding knobs in site-specific stimulating foot orthoses on postural balance and stability in older adults.
Methods: A crossover trial was conducted with 10 older adults aged 65 and above.

Objectives: To investigate whether a TiF varnish, a SnCl/AmF/NaF and chitosan-containing toothpaste (Elmex Opti-namel), and a fluoride-calcium-phospho-silicate-containing toothpaste (Biomin F) can reduce dentin hypersensitivity (DH) and improve oral health-related quality of life (OHRQoL) similarly to NaF varnish over 6 months.
Methods: Fifty-one patients/241 teeth were randomized into four groups. DH was measured using a 10-point visual analog scale after evaporative and tactile stimuli at baseline, immediately after application, and after 1, 3, and 6 months.
