This study examines the relationship between family socioeconomic status, parent-child activities, and young children’s digital development. Using the Family SES questionnaire, the parent-child activities questionnaire, and the 5 to 6 year old children’s number sense development scale as research instruments, 314 young children (M = 70.42, SD = 3.47). The results show that: (1) Family Socioeconomic Status can significantly positively predict the young children’s number sense development; (2) Parent-child activities play a partial mediating role in the relationship between family socioeconomic status and the young children’s number sense development. This study provides specific guidelines and recommendations for improving the young children’s number sense development.</div

Incorporating "care" into design education through games
“Universal Care” can be regarded as the ultimate goal for Universal Design. It implies that design takes care of not only the user, but also the environment, and all other people directly or indirectly influenced by the design. However, “care” as a concept is not necessarily recognised or incorporated in existing design education.In order to understand what “care” means for design education, the authors have developed two models: the “care” model addresses an Interior Design context, mapping the designer, the client/design, and the environment, to care-giving and care-receiving roles; the “relations” model shows the overlapping between Client, Design object, Design and Environment, for a product design context.Subsequently two case studies (“My home” and “VI Boccia grid”) were presented to illustrate how the models could inform Interior Design education and accessible product design innovation. The game “My home” enabled the Interior Design students to have a detailed conversation about the client’s needs and family relations, thus helping raise the designer’s awareness of care. The “VI Boccia grid” is a game designed for visually impaired people, and the whole design process highlighted issues critical for the success of accessible product development. Design educators, students, design researchers and practitioners can learn from the two models and the two case studies when applying “care” in their design process.<br

Thioketal-Based Electrochemical Sensor Reveals Biphasic Effects of l‑DOPA on Neuroinflammation
Neuroinflammation is linked closely
to neurodegenerative diseases,
with reactive oxygen species (ROS) exacerbating neuronal damage. Traditional
electrochemical sensors show promise in targeting cellular ROS to
understand their role in neuropathogenesis and assess therapies. Nevertheless,
these sensors face challenges in mitigating the ROS oxidation overpotential.
We herein introduce an ROS oxidation-independent nucleic acid sensor
for in situ ROS analysis and therapeutic assessment. The sensor comprises
ionizable and thioketal (TK)-based lipids with methylene blue-tagged
nucleic acids on a glass carbon electrode. ROS exposure triggers cleavage
within the sensor’s thioketal moiety, detaching the nucleic
acid from the electrode and yielding quantifiable results via square-wave
voltammetry. Importantly, the sensor’s low potential window
minimizes interference, ensuring precise ROS measurements with high
selectivity. Using this sensor, we unveil levodopa’s dose-dependent
biphasic effect on neuroinflammation: low doses alleviate oxidative
stress, while high doses exacerbate it. The TK-based sensor offers
a promising methodology for investigating neuroinflammation’s
pathogenesis and screening potential treatments, advancing neurodegenerative
disease research
<i>Let-7b</i> repletion selectively chemosensitizes <i>KRAS</i> mutant tumor cells.
<p>NSCLC cells A549 (<i>KRAS</i> mutant) and NIH-H1975 (<i>KRAS</i> wild-type), PDAC cells Panc-1 (<i>KRAS</i> mutant) and BxPC-3 (<i>KRAS</i> wild-type) were transfected with <i>let-7b</i> mimic (50 nM) or the scramble control (SCR, 50 nM) for 6 hours. The cells were then treated with paclitaxel (PTX, 0.1–50 nM) or gemcitabine (GEM, 5–150 nM or 5–150 μM) for 48 hours. Cell viability was assessed by the crystal violet assay. Each experiment was carried out at least 3 times. Data represent the mean ±SEM.</p
