Immune checkpoint inhibitors (ICIs) have made dramatic evolution in cancer management, yet their curative effect remains limited in most tumors characterized by "cold" immunophenotype. Immune remodeling by transforming "cold" tumor to "hot" one is essential to improve ICIs response, and gut microbiota modulation has emerged as a promising approach. Nevertheless, a significant challenge lies in the absence of reliable tools for early assessment of immune remodeling.

Immobilization of uranium via reductive precipitation is considered for remediation of uranium contaminated groundwater, however, the potential risk deriving from the migration of colloidal-state uranium challenges the remediation effectiveness. In this work, interaction and cotransport of uranium with bentonite colloids (BC) and humic acid (HA) were investigated under reductive conditions through sets of pyrite doped quartz sand columns. Uranium showed considerable mobility as the tetravalent state in the reductive media, both BC and HA significantly affected the transport of uranium, which were regulated by hydrochemical conditions.

Diabetic kidney disease (DKD) is recognized as the leading cause of end-stage renal disease (ESRD) and is related to progressive albuminuria, consequent to kidney destruction that involves podocyte mitochondrial dysfunction and apoptosis. Burgeoning evidence has reported that long Noncoding RNAs (lncRNAs) exert a vital role in DKD; however, their mechanism is largely unknown. Previously, we performed RNA sequencing (GSE199838) in human DKD samples and identified that lncRNA ENST00000458139 (lnc458) was significantly upregulated in DKD patients compared with healthy controls.

Objective: The biodegradation of methacrylate (MA)-based dental restoratives has been suggested to contribute to a loss of adhesion and subsequent detachment, or secondary caries, both major causes of restoration failure. Previous studies have demonstrated that intermolecular interactions between resin monomers may affect the hydrolytic-susceptibility of composites. Altering the intermolecular interactions by shielding or masking the hydrolytically-susceptible ester groups found in MA monomers could be an effective strategy to mitigate the biodegradation of resin composites.
