A sugary solution: Harnessing polysaccharide-based materials for osteoporosis treatment.

Osteoporosis, a prevalent skeletal disorder characterized by diminished bone density, compromised microstructure, and heightened fracture susceptibility, poses a growing public health concern exacerbated by aging demographics. Polysaccharides-based materials, derived from a diverse range of sources, exhibit exceptional biocompatibility. They possess a structure similar to the extracellular matrix, which can enhance cell adhesion in vivo, and demonstrate superior biological activity compared to artificial materials.

Differences in Genomic Alterations and Accumulations of Heavy Metals Between Advanced Non-small Cell Lung Cancer Patients with and without Bone Metastasis.

Integrating RNA-seq and scRNA-seq to explore the mechanism of macrophage ferroptosis associated with COPD.

Our study focused on whether macrophages ferroptosis is associated with the pathogenesis of chronic obstructive pulmonary disease (COPD) or not. We first identified macrophage module genes by weighted gene co-expression network analysis (WGCNA) in RNA sequencing (RNA-seq) date from COPD, and then identified macrophage marker genes by comprehensive analysis of single-cell RNA sequencing (scRNA-seq) data from COPD macrophages. There were 126 macrophage marker genes identified, and functional enrichment analyses indicated that ferroptosis pathway genes were significantly enriched.

Warm, not cold temperatures contributed to a Late Miocene reef decline in the Coral Sea.

Evidence shows that in the modern ocean, coral reefs are disappearing, and these losses are tied to climate change. However, research also shows that coral reefs can adapt rapidly to changing conditions leading some researchers to suggest that some reef systems will survive future climate change through adaptation. It is known that there were changes in the area covered by coral reefs in the past.

AnAzf1 acts as a positive regulator of ochratoxin A biosynthesis in Aspergillus niger.

Aspergillus niger produces genotoxic and carcinogenic ochratoxin A (OTA) that severely threatens human and animal health. Transcription factor Azf1 is essential in regulating fungal cell development and primary metabolism. However, its effect and mechanism on secondary metabolism are unclear.

Gasdermin D inhibition ameliorates neutrophil mediated brain damage in acute ischemic stroke.

Acute ischemic stroke (AIS) induces high level of neutrophils, which correlates inversely with patient survival. Pyroptosis induced by gasdermin D (GSDMD) has been shown to have an important role in the pathophysiology of several inflammatory disorders. The role of GSDMD in the high level of neutrophils after AIS is unknown.

Up/Down Tuning of Poly(ionic liquid)s in Aqueous Two-Phase Systems.

Thermally induced reversible up/down migration of poly(ionic liquid)s (PILs) in aqueous two-phase systems (ATPSs) was achieved for the first time in this study. Novel ATPSs were fabricated using azobenzene (Azo)- and benzyl (Bn)-modified PILs, and their upper and lower phases could be easily tuned using the grafting degree (GD) of the Azo and Bn groups. Bn-PIL with higher GD could go up into the upper phase and Azo-PIL come down to the lower phase when the temperature increased (>65 °C); this behavior was reversed at lower temperatures.

Contribution of prgH gene for Salmonella Pullorum to virulence and the expression of NLRP3, Caspase-1 and IL-1β in chickens.

Type III secretion system 1 (T3SS1) encoded by Salmonella pathogenicity island 1 (SPI1) is associated with invasion of host cells by Salmonella, PrgH encoded by prgH gene is an important component of T3SS1. This study aimed to explore the contribution of prgH gene for Salmonella Pullorum to virulence and the expression of NLRP3, Caspase-1 and IL-1β in chickens. A prgH gene deletion mutant (C79-13ΔprgH) was firstly generated, and the result of LD showed that deletion of prgH significantly decreased the virulence of Salmonella Pullorum in one-day-old HY-line white chickens, and the colonization also decreased in chickens after loss of prgH.
