The tight balance state and mechanism of disaster-resilient resources in karst small towns: a Chinese karst landform case study.

Karst small towns globally face challenges due to limited disaster-resilient resources, making it difficult to handle increasingly severe disaster environments. Improving the efficiency of disaster-resilient resource utilization and maintaining a tight balance state of disaster-resilient resources (TBS) are crucial for enhancing disaster adaptability and resilience. This study used urban and disaster data from a representative karst region in China (2017-2021) to conduct a quantitative analysis of TBS in karst small towns, exploring the mechanisms and interactions within this state and identifying obstacle factors.

Nobiletin: a potential erythropoietin receptor activator protects renal cells against hypoxia.

Tangerine peel is a traditional Chinese herb and has been widely applied in foods and medicine for its multiple pharmacological effects. Erythropoietin receptor (EPOR), a member of the cytokine receptor family, is widely expressed in multiple tissues in especial kidney and plays protective effects in adverse physiological and pathological conditions. We hypothesized that it might be EPOR agonists existing in Tangerine peel bring such renal benefits.

Research progress of non-coding RNA regulating the role of PANoptosis in diabetes mellitus and its complications.

Prognostic implications and therapeutic opportunities related to CAF subtypes in CMS4 colorectal cancer: insights from single-cell and bulk transcriptomics.

Cancer-associated fibroblasts (CAFs) significantly influence tumor progression and therapeutic resistance in colorectal cancer (CRC). However, the distributions and functions of CAF subpopulations vary across the four consensus molecular subtypes (CMSs) of CRC. This study performed single-cell RNA and bulk RNA sequencing and revealed that myofibroblast-like CAFs (myCAFs), tumor-like CAFs (tCAFs), inflammatory CAFs (iCAFs), CXCL14CAFs, and MTCAFs are notably enriched in CMS4 compared with other CMSs of CRC.

Clinical characteristics of IgG4-related retroperitoneal fibrosis in a cohort of 117 patients with idiopathic retroperitoneal fibrosis: a retrospective study.

In recent years, the identification of IgG4-related diseases has brought to light a significant association with fibrous disorders, including RPF, which were once considered independent. In this comprehensive cohort study, we performed a comparative analysis of the demographic, clinical, laboratory, histopathological, and therapeutic characteristics between patients with IgG4-related RPF and those with idiopathic retroperitoneal fibrosis (iRPF).

Spillover effect of children's education on parental physical functioning over the life course.

Parental well-being is linked to the life chances of adult children in later life. Despite accumulated knowledge on the role of children's education on parental longevity in developed contexts, it remains unknown how children's education may influence the trajectories of parental physical well-being over the aging process, particularly in developing contexts. Using a growth curve model and four-wave data from the China Health and Retirement Longitudinal Study, this study examines the association between children's education and parental physical functioning trajectories as parents age.
