Tennis equipment modifications, such as smaller rackets and low-compression balls, are increasingly being used because they can better align with beginners' physical capabilities, enhancing learning and engagement. This scoping review aimed to map current research on equipment modifications for beginner tennis players, identifying how these modifications impact skill acquisition, game performance, biomechanical variables, psychological aspects, and coaches' perspectives. Searches across the Web of Science, Scopus, PubMed, and SPORTDiscus, along with expert input following the PRISMA procedures, yielded 35 studies. These studies involved empirical interventions related to scaled tennis equipment for beginners and were published in English or Spanish. Narrative reviews and studies lacking empirical data were excluded. The results indicate that equipment modifications enhance control, technique, and engagement in skill acquisition, improve tactical play with more aggressive strokes, and reduce joint stress, thereby minimizing injury risk. Psychological benefits include greater enjoyment and self-efficacy, and coaches strongly support these adaptations. These findings suggest practical implications for junior tennis development. However, future research should focus on expanding real-game applications, increasing participant diversity, and conducting detailed psychological and biomechanical assessments to further optimize player progression.

This study investigates the physicochemical properties of hydrogels based on PVA and PVP crosslinked with PEGDA, focusing on their swelling capacity, surface roughness, incubation behavior, and structural modifications upon bioactive component incorporation. Swelling analysis demonstrated that the amount and molecular weight of PEGDA significantly influences the hydrogels' sorption properties, with the highest swelling coefficient observed for samples with 2 mL PEGDA (575 g/mol) due to a looser network structure, while the lowest was recorded for 2.5 mL PEGDA (700 g/mol), indicating a denser network.

The widespread adoption of chimeric antigen receptor (CAR) T-cell therapy has been limited by complex, resource-intensive manufacturing processes. This review discusses the latest innovations aiming to improve and streamline CAR T-cell production across key steps like T-cell activation, genetic modification, expansion, and scaling. Promising techniques highlighted include generating CAR T cells from non-activated lymphocytes to retain a stem-like phenotype and function, non-viral gene transfer leveraging platforms like transposon and CRISPR, all-in-one fully automated bioreactors like the CliniMACS Prodigy and the Lonza Cocoon, rapid CAR T-cell manufacturing via abbreviating or eliminating ex vivo T-cell culture, implementing decentralized point-of-care automated manufacturing platforms, and optimizing centralized bioreactor infrastructure integrating end-to-end automation.

We examined whether the glucose levels and awareness of individuals without diabetes changed after using a sensor-based intermittently scanned continuous glucose monitoring (isCGM) system in their daily lives. Japanese individuals without a diabetes diagnosis wore the isCGM system while maintaining a normal lifestyle during the baseline period. A certified diabetes educator coached them on how to improve their lifestyle based on information from sensor data, food journals, and body composition.

This study investigates the synthesis and characterization of Plant-Ag-graphene nanocomposites through a combination of spectroscopic and microscopic techniques, the nanocomposites were formed by catalyzing silver nanoparticles with plant extracts, and the resulting structures were analyzed using advanced instrumentation. In the FTIR analysis, distinctive peaks were observed at 3340 cm⁻1 (O-H stretching), 1740 cm⁻1 (C = O stretching), and 1050 cm⁻1. When compared to silver nanoparticles, the nanocomposites exhibited altered peak intensities, indicating modifications in chemical bonding.
