The immunotherapeutic effect elicited by photodynamic therapy (PDT) is attenuated tumor defense mechanisms associated with glutamine metabolism, including the metabolic regulation of redox homeostasis and limitation immunosuppressive microenvironment (ITM). Herein, a carrier-free nanobooster C9SN dual synergistic effects was constructed self-assembly glutaminase (GLS) inhibitor compound 968 (C968) photosensitizer Chlorin e6. C968-mediated GSH deprivation through inhibiting metabolism...

Abnormal tumor metabolism creates a complex immune microenvironment that plays dominant role in the metastasis of triple-negative breast cancer (TNBC). TNBC is insensitive to checkpoint blockade (ICB) therapy because insufficient cytotoxic T lymphocyte (CTL) infiltration and hyper-lactic acid-suppressive caused by abnormal glycolysis. Herein, we propose an amplified strategy based on lactic acid regulation reprogram immunosuppressive (ITM) combine it with ICB achieve enhanced antitumor...

The hypopermeability and hypoxia in the tumor milieu are important factors that limit multiple treatments. Herein, reactive oxygen species (ROS)-triggered self-assembled nanoparticles (RP-NPs) was constructed. natural small molecule Rhein (Rh) encapsulated into RP-NPs as a sonosensitizer highly accumulated at site. Then tissue-permeable ultrasound (US) irradiation induced apoptosis of cells through excitation Rh acoustic cavitation, which prompted rapid production large amounts ROS hypoxic...

Abstract Background Job burnout is a prevalent and emerging challenge in the primary medical system, causing mass turnover, especially of staff. Little attention has been paid to different dimensions job (emotional exhaustion, personality disintegration, reduced sense achievement), which may hinder efforts tackle high turnover intention among From perspective conservation resources theory, social support psychological capital are basic with potential diminish thus lower intention. However,...

Ferroptosis combined with photodynamic therapy (PDT) has emerged as a powerful approach to induce cancer cell death by producing and accumulating lethal reactive oxygen species (ROS) in the tumor microenvironment (TME). Despite its efficacy safety, challenges persist delivering multiple drugs site for enhanced antitumor improved tissue targeting. Hence, we designed method of inducing ferroptosis through laser-mediated human homologation-specific efficient activation, which is also higher...

Abstract RelA, also known as nuclear factor kappa B p65, plays a crucial role in the pathogenesis of various liver diseases. However, specific RelA hepatocytes during progression metabolic dysfunction-associated steatotic disease (MASLD) is not well understood. This study explored relationship between impaired signaling and lipid metabolism disorders hepatocytes, how they synergistically contribute to advancement MASLD. We assessed changes, regulatory relationships, impacts remodeling on...

The combined effects of physical activity (PA) and nitrogen dioxide (NO2) on fasting plasma glucose (FPG) levels have rarely been studied. This study aimed to examine whether long-term exposure NO2 attenuates the association between PA FPG in non-diabetic older adults. A total 2600 elderly Chinese adults were included this cross-sectional study. data collected using International Physical Activity Questionnaire (IPAQ). Space-Time Extra-Trees model was utilized estimate annual concentration...

The shortage of primary medical staff is an important issue in the management health human resources, and it also a problem that all countries world need to face together. Since 2009, China has implemented new series system reforms loss have been alleviated accordingly. However, large population difficult distribute resources evenly across regions. This study aimed explore current status turnover intention its relationship with psychological capital, social support, job burnout, as well how...

Monascus-fermented red mold rice (RMR) has excellent physiological efficacy on lipid metabolism and liver function. This study investigated the ameliorative effects of monascuspiloin (MP) from RMR alcoholic injury in mice, further clarified its mechanism action. Results showed that MP intervention obviously ameliorated function mice with over-drinking. In addition, dietary reduced MDA levels increased CAT, SOD, GSH levels, thus alleviating oxidative stress induced by excessive drinking. 16S...
