The purpose of this study is to re-examine the concepts of health services utilization presented by White and his colleagues in 'The Ecology of Medical Care'. We re-test their model in a rural population in the southern United States using longitudinal instead of cross-sectional data and find that the general principles of the 'Ecology' model do, indeed, apply to rural populations like Rougemont/Bahama. Use of this model has implications for modifying and improving the organization of the health care delivery system and for a fundamental change of emphasis in medical education.

S-Palmitoylation is a reversible post-translational modification involving saturated fatty acid palmitate-to-cysteine linkage in the protein, which guides many aspects of macrophage physiology in health and disease. However, the precise role and underlying mechanisms of palmitoylation in infection of macrophages remain elusive. Here, we found that infection induced the expression of zinc-finger DHHC domain-type palmitoyl-transferases (ZDHHCs), particularly ZDHHC2, in mouse macrophages.

SOX9 is a crucial transcriptional regulator of cartilage development and homeostasis. Dysregulation of is associated with a wide spectrum of skeletal disorders, including campomelic dysplasia, acampomelic campomelic dysplasia, and scoliosis. Yet how variants contribute to the spectrum of axial skeletal disorders is not well understood.

Background: Makorin ring finger protein 3 gene (MKRN3) gene mutation is the most common genetic cause of central precocious puberty (CPP) in children. Due to the lack of ideal MKRN3-modified animal model (MKRN3-modified mice enter puberty only 4-5 days earlier than normal mice), the related research is limited.
Methods: Therefore, the MKRN3-modified rabbit was developed using CRISPR (clustered regularly interspaced short palindromic repeats) gene editing technology.

Nasopharyngeal carcinoma (NPC) is an Asia-prevalent malignancy, yet its genetic underpinnings remain incompletely understood. Here, a transcriptome-wide association study (TWAS) is conducted on NPC, leveraging gene expression prediction models based on epithelial tissues and genome-wide association study (GWAS) summary statistics from 1577 NPC cases and 6359 controls of southern Chinese descent. The TWAS identifies VAMP8 on chromosome 2p11.
