Nursing students and the internet: a reflection of digital ethics.

Objectives: to identify how first-year nursing students use cyberspace and propose an orientation guide with criteria guiding the use of cyberspace.

Methods: qualitative and descriptive research, carried out with 24 nursing students from a federal public institution in Rio de Janeiro. Data collection was carried out through semi-structured interviews.

GrB-Fc-KS49, an anti-EMP2 granzyme B fusion protein therapeutic alters immune cell infiltration and suppresses breast cancer growth.

Background: Granzyme B (GrB) is a key effector molecule, delivered by cytotoxic T lymphocytes and natural killer cells during immune surveillance to induce cell death. Fusion proteins and immunoconjugates represent an innovative therapeutic approach to specifically deliver a deadly payload to target cells. Epithelial membrane protein-2 (EMP2) is highly expressed in invasive breast cancer (BC), including triple-negative BC (TNBC), and represents an attractive therapeutic target.

Streptococcus mutans serotyping, collagen-binding genes and Candida albicans in dentin carious lesions: a molecular approach.

Objectives: This cross-sectional study aimed to evaluate the occurrence of Streptococcus spp., Streptococcus mutans, its serotypes (c, e, f, and k), collagen-binding genes (cnm/cbm), and Candida albicans in medium deep (D2) and deep (D3) dentin carious lesions of permanent teeth.

Materials And Methods: Carious dentin was collected from D2 (n = 23) and D3 (n = 24) lesions in posterior teeth from 31 individuals.

Sustainable Carbon Dots Loaded into Carboxymethylcellulose Based Hydrogels for Uterine Cancer Bioimaging.

: The development of innovative materials for disease diagnostics and therapeutics is a fast-growing area of scientific research. In this work, we report the development of innovative hydrogels incorporating carbon dots (Cdots) for bioimaging purposes. : The Cdots were prepared using a sustainable and low-cost process, starting with an underused fiber from the Brazilian semiarid region.

Asymmetric Membranes Obtained from Sulfonated HIPS Waste with Potential Application in Wastewater Treatment.

The recovery and reuse of high-impact polystyrene (HIPS) into high-value products is crucial for reducing environmental thermoplastics waste and promoting sustainable materials for various applications. In this study, asymmetric membranes obtained from sulfonated HIPS waste were used for salt and dye removals. The incorporation of sulfonic acid (-SOH) groups into HIPS waste by direct chemical sulfonation with chlorosulfonic acid (CSA), at two different concentrations, was investigated to impart antifouling properties in membranes for water treatment.
