Background: Exosomes derived from primary chondrogenic stem/progenitor cells (CSPCs-EXOs) show promise in cartilage repair due to their immunomodulatory and regenerative properties. However, their specific therapeutic potential in osteoarthritis (OA), especially in modulating immune responses and enhancing chondrocyte function, requires further exploration. This study aims to clarify CSPCs-EXOs' effects on OA by investigating their role in chondrocyte proliferation, migration, inflammation inhibition, and cartilage regeneration.

The aim of this study was to investigate the predictive value of SII at different time points after admission for functional outcome at discharge in patients with intracerebral hemorrhage (ICH).
Methods: The clinical data of patients with ICH who were treated at a medical center for neurological diseases in China between October 2012 and April 2022 were analyzed in this retrospective study.
Microplastics (MPs), a pervasive pollutant in aquatic environments, are increasingly recognized for their detrimental effects on aquatic organisms. However, the present understanding of their impact on phytoplankton, particularly freshwater microalgae, remains limited. Furthermore, previous studies have predominantly focused on MP particles, largely overlooking the most prevalent form of MPs in aquatic settings-fibers.

Bisphenol A (BPA) is an endocrine disruptor that has adverse effects on lipid metabolism. However, most of the current studies on the effects of BPA on lipid metabolism in fish have focused on middle- and short-term exposure tests. The aim of this study was to investigate the effects of long-term BPA exposure on liver lipid metabolism in zebrafish.

We aimed to evaluate the effect of ultra-early treatment on functional outcomes and mortality in patients with poor-grade aSAH via a systematic review and meta-analysis.
Methods: We performed a literature search in the PubMed, MEDLINE, and Web of Science databases.
In the field of developmental neurobiology, accurate and ordered regulation of the cell cycle and apoptosis are crucial factors contributing to the normal formation of the neural tube. Preliminary studies identified several genes involved in the development of neural tube defects. In this study, we established a model of developmental neural tube defects by administration of retinoic acid to pregnant rats.

Results revealed that at 2 hours after cerebral contusion and laceration injury, aquaporin 4 expression significantly increased, brain water content and blood-brain barrier permeability increased, and the number of pinocytotic vesicles in cerebral microvascular endothelial cells increased. In addition, the mitochondrial accumulation was observed.

Methods: The differential expressions of MDM2 gene and protein in SHG-44 cells were detected by cDNA microarray and Western blot, respectively, before and after treatment of ATRA. The expressions of MDM2 protein in WHO grade II and grade IV astrocytomas were determined by immunohistochemical streptavidin-peroxidase method.
