A technique that can direct the repair of a genetic mutation in a human chromosome using the DNA repair machinery of the cell is under development. Although this approach is not as mature as other forms of gene therapy and fundamental problems continue to arise, it promises to be the ultimate therapy for many inherited disorders. There is a continuing effort to understand the potential and the limitations of this controversial approach.

Clinical trials that employ human challenge, also known as controlled human infection models (CHIM), have rapidly advanced vaccine development for multiple pathogens, including at least 30 disease models to date. CHIM studies, championed by networks of researchers, regulators, ethicists, technical experts, and other stakeholders, limit exposure of individuals to an investigational product, de-risk product investments, identify correlates of protection, and most importantly provide a prompt readout of vaccine efficacy. While CHIM studies provide multiple advantages, important challenges exist, including strengthening the relevance and comparability of CHIM study results to efficacy trials in endemic areas, particularly in resource-limited settings.

Maintaining human body temperature in both high and low-temperature environments is fundamental to human survival, necessitating high-performance thermal insulation materials to prevent heat exchange with the external environment. Currently, most fibrous thermal insulation materials are characterized by large weight, suboptimal thermal insulation, and inferior mechanical and waterproof performance, thereby limiting their effectiveness in providing thermal protection for the human body. In this study, lightweight, waterproof, mechanically robust, and thermal insulating polyamide-imide (PAI) grooved micro/nanofibrous aerogels were efficiently and directly assembled by electrospinning.

The aim is to unveil the useful value of breastfeeding for lactating women in a prison environment, based on Max Scheler's axiological perspective. This work was a qualitative, developed in a prison unit in Rio de Janeiro, where seven lactating women were interviewed. The phenomenological interview was used for data collection, while Laurence Bardin's content analysis was used for data analysis and treatment.

The Homeless Population (HP) has grown exponentially in the last decade, causing different challenges for the Brazilian Unified Health System, especially during the COVID-19 pandemic. A cross-sectional, descriptive, and exploratory study, with triangulated quantitative and qualitative methods, was conducted from 2020 to 2022, exploring care practices geared to the HP in Belo Horizonte. The quantitative stage adopted official datasets from the health and social assistance secretariats, and 48 semi-structured interviews and four focus groups were conducted in the qualitative stage, totaling 86 participants.

Pancreatic ductal adenocarcinoma (PDAC) driven by the mutation presents a formidable health challenge because of limited treatment options. MRTX1133 is a highly selective and first-in-class KRAS-G12D inhibitor under clinical development. Here, we report that the advanced glycosylation end product-specific receptor (AGER) plays a key role in mediating MRTX1133 resistance in PDAC cells.
