Home care service for children/adolescents with special health care needs: family perception.

Objective: To apprehend the family's perception of the care provided by home care services to children and adolescents with special health needs.

Method: Qualitative, exploratory-descriptive study, carried out with 15 family members of children and adolescents with special health needs served by Home Care Services in seven municipalities in Paraíba, in 2021, selected from nine municipalities identified by previous studies. Data were collected using semi-structured interviews carried out remotely through telephone calls.

A new standardization for the use of chicken embryo: selection of target from the phage display library and infection.

The filamentous bacteriophage M13KO7 (M13) is the most used in phage display (PD) technology and, like other phages, has been applied in several areas of medicine, agriculture, and in the food industry. One of the advantages is that they can modulate the immune response in the presence of pathogenic microorganisms, such as bacteria and viruses. This study evaluated the use of phage M13 in the chicken embryos model.

Meanings attributed to health-related quality of life by caregivers of adolescents with diabetes.

Objective: to interpret the meanings attributed to the health-related quality of life by caregivers of adolescents with type 1 diabetes mellitus.

Methods: qualitative, descriptive-exploratory study of 14 caregivers of adolescents with diabetes developed at the reference outpatient clinic for endocrine diseases in a city in the state of Paraíba. Interviews were performed between May and September 2021.

Rho GTPase activating protein 21-mediated regulation of prostate cancer associated 3 gene in prostate cancer cell.

The overexpression of the prostate cancer antigen 3 (PCA3) gene is well-defined as a marker for prostate cancer (PCa) diagnosis. Although widely used in clinical research, PCA3 molecular mechanisms remain unknown. Herein we used phage display technology to identify putative molecules that bind to the promoter region of PCA3 gene and regulate its expression.

Unveiling the characteristics of D4 and R4 aptamers for their future use in prostate cancer clinical practice.

The DNA and RNA aptamers D4 and R4, respectively, emerged from the modification of PC-3 cell-binding aptamer A4. Our objective was to characterize the aptamers in silico and in vitro and begin to identify their target molecules. We represented their structures using computational algorithms; evaluated their binding to several prostate cell lines and their effects on the viability and migration of these cells; and determined their dissociation constant by flow cytometry.
