Is There Polyamorphism in Amorphous Indomethacin? Investigating the Physicochemical Properties of Amorphous Indomethacin with Different Thermal History.

Polyamorphism in organic molecules is a poorly understood and controversial phenomenon related to amorphous materials. Although very few studies, including our own, have demonstrated the existence of polyamorphism in drug molecules, this solid-state phenomenon is still very elusive and the investigation of its occurrence in other drugs is fundamental to understand its formation. Indomethacin (IND) has been recently discussed in the literature as a potential drug exhibiting polyamorphism.

Oxidative balance score is associated with increased risk of sarcopenia and sarcopenic obesity in non-elderly adults: results from NHANES 2011-2018.

Background: Sarcopenia and obesity, two prevalent health conditions, often coexist and exacerbate each other's impact, increasing the risk of chronic diseases and mortality. This dual condition is termed "sarcopenic obesity." The correlation between oxidative stress (OS) and sarcopenia or obesity was established, and the oxidative balance score (OBS) can serve as an indicator of overall dietary or lifestyle-related OS exposure within an individual.

In this research, the reversal effects and associated mechanisms of PL in 5-Fluorouracil (5-FU) resistance colorectal cancer were investigated both in vitro and in vivo.

Ag/AgS plasmonic heterostructure promotes piezoelectric photocatalytic activity of BiFeO nanofibers for degradation of ciprofloxacin and energy conversion.

Piezoelectric effect, plasma effect and semiconductor heterostructure are important strategies for enhanced photocatalytic performance. Herein, we developed a novel heterostructure piezoelectric photocatalyst, Ag/AgS/BiFeO (AAS/BFO), for photocatalytic degradation of ciprofloxacin from water. Experimental results verified the enhancement of combining heterostructure piezoelectric polarization effect, which promotes efficient migration and separation of photogenerated carriers due to the localized surface plasmon resonance effect of Ag nanoparticles.

Elevated CD10 neutrophils correlate with non-response and poor prognosis of CD19 CAR T-cell therapy for B-cell acute lymphoblastic leukemia.

Background: The primary challenges in CD19-specific chimeric antigen receptor T-cell (CD19 CAR T) therapy for patients with refractory/relapsed B-cell acute lymphoblastic leukemia (r/r B-ALL) are non-response and relapse; it is urgent to reveal these mechanisms. Neutrophils play a critical role in the immunosuppressive tumor microenvironment (TME), which can hinder CAR T efficacy. Our previous research identified a subset of immunosuppressive neutrophils with a special phenotype (CD14CD10CD45HLA-DRSSC, termed CD10 neuts), which suppress T cell function.

Disorder-assisted real-momentum topological photonic crystal.

Topological defects and disorder counteract each other. Intuitively, disorder is considered detrimental, requiring efforts to mitigate its effects in conventional topological photonics. We propose a counter-intuitive approach that exploits a real-momentum topological photonic crystal that harnesses real-space disorder to generate a Pancharatnam-Berry phase, without disrupting the momentum-space singularity originating from bound states in the continuum.

Association of immunosuppressive CD45CD33CD14 CD10HLA-DR neutrophils with poor prognosis in patients with lymphoma and their expansion and activation through STAT3/arginase-1 pathway .

Abnormal Temperature Dependence of Huang-Rhys Factor and Exciton Recombination Kinetics in CsPbBr Perovskite Quantum Dots.

Anomalous thermal behaviors of excitonic luminescence in CsPbBr perovskite quantum dots (PQDs) were observed. It is found that the main luminescence peak originated from the excitonic radiative recombination assisted by the longitudinal-optical (LO) phonon, and its integrated intensity first declines as the temperature varies from 10 to 150 K and then turns to increase at ∼160 K, reaching a maximum value at 300 K. A model considering the thermal detrapping and transfer of electrons from a trap level is developed to interpret these abnormal thermal behaviors of the luminescence from the PQDs.
