Background: Because an estimated 50% to 80% of the skin's lifetime sun damage is thought to occur in childhood and adolescence, it is during these critical periods that intense, intermittent sun exposure causing burning increases melanoma risk.
Methods: A 1997 telephone survey of 503 households evaluated parental attitudes about their child having a tan, and ease of practicing sun protection, sun protection methods used, and sunburning on 5 successive summer weekends.
Results: In a random sample of 1 child from each household, 13% of children sunburned during the past week or weekend, and 9% of their parents experienced a sunburn during the past weekend. Children's sunburn was significantly associated with sunburn in the adult respondent, increasing age of the child, having fair skin, being white, and using sunscreens. Duration and peak hours of sun exposure were associated for children and parents. Sunscreen with a sun protection factor of at least 15 was the predominant form of sun protection used. Sunscreen use in children was significantly associated with longer duration of sun exposure, sunny weather conditions, younger age, fair skin, a history of sunburns before this study, a family history of skin cancer, and a higher family income. Feeling that a tan appeared healthy was associated with male gender of the adult and increasing age of the child. Complimenting the child on the appearance of a tan was associated with male gender of the adult, older children, children with skin type reported as olive or dark, and lower educational levels.
Conclusion: Although there has been a promising initial effort to alert parents to the need to protect their children from sunburns, many view a tan as healthy and do not effectively implement sun protection behaviors for their children, which results in sunburns. Sun protection that prevents sunburning could be achieved by more children seeking shade, wearing protective clothing, limiting exposure during peak hours, and effectively using sunscreen.

Background: Flavonoids are naturally occurring dietary phytochemicals with significant antioxidant effects aside from several health benefits. People often consume them in combination with other food components. Compiling data establishes a link between bioactive flavonoids and prevention of several diseases in animal models, including cardiovascular diseases, diabetes, gut dysbiosis, and metabolic dysfunction-associated steatotic liver disease (MASLD).

Shipboard domestic sewage, encompassing both black water and gray water, has the potential to transport significant quantities of environmentally harmful microplastics, a concern that has garnered increasing global attention. In this study, Fourier infrared (FTIR) detection was used to detect microplastics in marine domestic wastewater. The primary objective was to evaluate the abundance and characteristics of microplastics present in ship domestic sewage, investigate potential sources and influencing factors, and assess the ecological risks associated with ship sewage through analyses of microplastic abundance and hazard indices.

Tumor hypoxia is one of key challenges in deep tumor photodynamic therapy (PDT), and how to fix this issue is attracting ongoing concerns worldwide. This work demonstrates dually fluorinated unimolecular micelles with desirable and stable oxygen-carrying capacity, high cellular penetration, and integrative type I & II PDT for deep hypoxic tumors. Dually fluorinated star copolymers with fluorinated phthalocyanines as the core are prepared through photoinitiated electron/energy transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization under irradiation with NIR LED light at room temperature, followed by assembly into unimolecular micelles.

Background: Acute pharyngitis (AP) is a common condition marked by inflammation of the oropharynx, which can lead to severe throat swelling, breathing difficulties, and even suffocation, significantly impacting quality of life. Despite the beneficial anti-inflammatory activity of Glycyrrhizae Radix Et Rhizoma (GRER) and Isoliquiritigenin (ISL), their pharmacological mechanisms against AP remain unclear.
Purpose: This study explores the mechanisms by which GRER treats AP, utilizing both transcriptomics and metabolomics approaches.

As an accelerated electron transfer device, the influence of microbial electrochemical snorkel (MES) on soil greenhouse gas production remains unclear. Electron transport is the key to methane production and denitrification. We found that the NO amount of the MES treatment was comparable to the control however the cumulative CO and CH emissions were reduced by 50% and 41%, respectively.
