Polygonatum cyrtonema (PC) is a traditional Chinese herb used in both food and medicine with considerable bioactivity. The nine-steam processed pieces of PC are the main form of clinical application, while research has focused on the polysaccharide of their crude form. This study evaluated the physicochemical characteristics and protective effects of polysaccharides from both crude PC (PCP) and nine-steamed PC (NPCP) against cyclophosphamide (CTX)-induced immunosuppression.

Aims: We aimed to investigate the vascular and downstream effects and drug pharmacokinetics in a porcine coronary model treated with MagicTouch-SCB (MT-SCB), Selution-SRL-SCB (SEL-SCB), Agent PCB, and plain old balloon angioplasty (POBA).
Methods: Twenty-eight coronary arteries from 10 pigs were treated with one of three drug-coated balloons (DCBs) (n = 7 for each) or POBA (n = 7) with 28 days follow-up.

Background: Osteoporosis (OP) is a progressive metabolic bone disease characterized by impaired bone microarchitecture, decreased bone strength, and dysregulated bone remodeling, leading to an increased risk of fractures. Among osteoporotic fractures, osteoporotic vertebral compression fractures (OVCF) are the most common and can significantly impact patients' quality of life. Growing evidence suggests that microRNAs (miRNAs) play a crucial role in bone homeostasis by regulating osteoblast differentiation, bone metabolism, and remodeling processes.

However, differentiation syndrome (DS) can be a life-threatening complication of induction therapy. It is considered to result from a severe systemic inflammatory response mediated by increased expression of cytokines, chemokines, and adhesion molecules on differentiating blast cells.

The wide-bandgap and p-type semiconductor layer plays a crucial role in the antimony selenide (SbSe) solar cells, as it can provide carrier confinement and inhibit interface recombination. In this work, the tellurium (Te) thin layer is innovatively applied in superstrate SbSe solar cells, which is further in situ oxidized to wide-bandgap (3.67 eV) tellurium oxide (TeO).

Trigonal selenium (t-Se) is a promising wide-band-gap photovoltaic material with a high absorption coefficient, abundant resources, simple composition, nontoxicity, and a low melting point, making it suitable for absorbers in advanced indoor and tandem photovoltaic applications. However, severe electrical losses at the rear interface of the t-Se absorber, caused by work function and lattice mismatches, limit the voltage output and overall performance. In this study, a strategy to enhance carrier transport and collection by modifying interfacial chemical interactions is proposed.

As the most prevalent subtype of lung cancer, lung adenocarcinoma (LUAD) is closely associated with angiogenesis, which is fundamental to its progression. ADAM8 (A disintegrin and metalloproteinase 8) is an enzyme associated with tumor invasion, while its implications in LUAD angiogenesis are a field that awaits exploration. A thorough investigation into the impacts of ADAM8 on LUAD angiogenesis could contribute to the development of therapeutic drugs for LUAD.

However, there is limited research on the mechanisms underlying fibroblast-like synoviocyte senescence and its impact on osteoarthritis progression. Here, we elucidate a positive correlation between fibroblast-like synoviocyte senescence and osteoarthritis progression and reveal that GATD3A deficiency induces fibroblast-like synoviocyte senescence.

Using magnetron sputtering technology, NiCr/NiSi thin-film thermocouples (NiCr/NiSi TFTCs) with different junction sizes were fabricated on the proton exchange membrane (PEM). These NiCr/NiSi TFTCs exhibit excellent compactness, with thickness and planar dimensions in the micrometer range.

Background: SHR4640, a highly selective URAT1 inhibitor, was evaluated to investigate its inhibitory effects on CYP2C8 and CYP3A4 in vivo clinical trial. This study assessed the pharmacokinetic (PK) impact of SHR4640 when co-administered with the CYP2C8 probe substrate repaglinide and the CYP3A4 probe substrate midazolam.
Research Design And Methods: In this single-center, randomized, double-blind, placebo-controlled study, participants were randomly allocated in a 1:1:1 ratio to SHR4640 Group A, SHR4640 Group B, and placebo group and received oral repaglinide, midazolam, SHR4640 or placebo at specific times.
Background: Primary immune thrombocytopenia (ITP) is an immune-mediated hematologic disorder characterized by a reduction in platelet count, increasing the risk of bleeding. Recent studies have indicated a close association between alterations in gut microbiota and the development of ITP. However, the mechanisms by which gut microbiota influence the occurrence and progression of ITP through plasma metabolites remain poorly understood.

Systemic lupus erythematosus (SLE) is an autoimmune disorder that commonly affects the skin, kidneys, joints, and various other systemic tissues, with its development intricately linked to the process of immunosenescence. Quercetin (QC), a phytochemical that occurs naturally, demonstrates many different biological capabilities, such as antibacterial, antioxidant, and anti-inflammatory activities. Our investigation found that QC effectively reduced kidney damage and relieved mesenteric lymph nodes (mLNs) swelling in MRL/lpr lupus mice.

Consequently, this transformation leads to both a compromised ability to maintain lumen permeability and alterations in vascular structure, which hampers the preservation of blood-brain barrier integrity. This study aimed to investigate inflammation-induced EndoMT and its etiology, with the goal of impeding the infiltration of peripheral inflammation into the central nervous system.
