Article Abstract

Women who inherit heterozygous mutations in the BRCA2 gene have an increased risk of developing cancer, mainly breast and ovarian tumors. A particular BRCA2 mutation (c.156_157insAlu) is exclusively found in families of Portuguese ancestry and is present in approximately 30% of all Portuguese families with hereditary breast and ovarian cancers. We report the generation and characterization of the first iPSC line from a female donor harboring the Portuguese BRCA2 founder mutation. Skin fibroblasts were reprogrammed using a non-integrative Sendai virus. These iPSCs are a valuable tool to study the origin of BRCA2-associated cancer in its earliest phases.

Objectives: Urinary calculi are characterized by a high recurrence rate, and patients' adherence to self-management after discharge directly affects health outcomes. Traditional offline follow-up models often face problems such as poor compliance and uneven allocation of medical resources, making it difficult to meet individualized health management needs. Remote follow-up provides a novel solution to optimize long-term management, improve health literacy, and enhance clinical outcomes.

Background: Diabetic foot ulcer (DFU) represents a challenging complication of diabetes mellitus, characterized by slow healing processes. Protein kinase C delta (PKCδ) has been identified as a significant factor in the pathogenesis of various diabetic complications, including DFU. However, the precise underlying mechanisms remain to be fully elucidated.

We introduce a theoretical and computational framework for extracting the pressure equation of state (EoS) of an active suspension from its steady-state sedimentation profile. As EoSs are prerequisites for many theories in active matter, determining how pressure depends on key parameters such as density, activity, and interparticle interactions is essential to make quantitative predictions relevant to materials design and engineering applications. Focusing on the one-dimensional active Brownian particle (1D-ABP) model, we show that the pressure measured in a homogeneous periodic system can be recovered from the spatial profiles established in sedimentation equilibrium.

Metabolic benefits conferred by duplication of the facilitated trehalose transporter in Lepidoptera.

Integrative Science Center of Germplasm Creation in Western China (Chongqing) Science City, Biological Science Research Center, Southwest University, Chongqing, China.

In addition to being one of the primary processes for the formation and expansion of gene families, gene duplication also establishes the basis for the diversity and redundancy of gene functions, providing an abundance of genetic resources and a potent adaptive potential for biological evolution. Trehalose is a high-quality carbon source and blood sugar in insects. However, recent theoretical developments suggest that mechanisms for facilitated trehalose transport in lepidopteran insects remain relatively scarce.
