Pentachlorophenol (PCP), a persistent organic pollutant, has been banned in many countries, but it is still used in China as a wood preservative, molluscicide, or reagent for fish-pond cleaning, which may pose risks to the ecosystem and humans. However, data on the occurrence of PCP in the environment are scarce in the recent decade. The Yangtze River was regarded as a priority area of PCP pollution according to previous documents. This study aimed to examine the spatial distribution of PCP in the Yangtze River water, the differences in dry and wet seasons, the ecological risk for aquatic organisms, and its removal efficiency in tap water treatment plants. The river water samples (n = 144) were collected from the upper, middle, and lower reaches across ten provinces (or municipalities) in December 2020 and June 2021, respectively. PCP was detected in 88.9% of all the samples, ranging from

Diabetes nephropathy (DN) is a severe diabetic chronic microvascular complication and the major cause of end-stage renal disease (ESRD). Our study aimed to investigate the effects of isoliquiritigenin (ISL) a natural flavonoid compound on DN and to explore the underlying mechanisms. The db/db mice were received intragastric treatments of ISL (5, 10, or 20 mg/kg), vehicle or positive drug metformin (300 mg/kg) once a day for 12 weeks, and the db/m mice treated with vehicle were used as controls.

Chimeric antigen receptor T-cell (CAR-T) therapy is a revolutionary approach in cancer treatment. More than 10 CAR-T products have already approved on market worldly wide, and they use either gamma retroviral vectors or lentiviral vectors to deliver the CAR gene. Both vectors have the ability to effectively and persistently integrate the CAR gene into T cells.

Vegetation productivity and ecosystem carbon sink capacity are significantly influenced by seasonal weather patterns. The time lags between changes in these patterns and ecosystem (including vegetation) responses is a critical aspect in vegetation-climate and ecosystem-climate interactions. These lags can vary considerably due to the spatial heterogeneity of vegetation and ecosystems.

Introduction: Degenerative lumbar scoliosis (DLS) often causes various issues such as neural symptoms and osteoporosis (OP). Vertebral bone quality (VBQ) is a crucial factor that surgeons take into consider prior to surgery. However, little attention has been given to the use of VBQ in evaluating vertebral bone mass in DLS patients.

Sewer overflows are a potential source of emerging contaminants to urban waters, posing a threat to ecosystems and human health. Herein, the performance and mechanism of ferrate(Ⅵ) (Fe(Ⅵ))/peroxymonosulfate (PMS), Fe(Ⅵ)/peroxydisulfate (PDS), and Fe(Ⅵ)/percarbonate (SPC) for the degradation of ofloxacin (OFL) in overflows were comparatively investigated. These systems achieved efficient degradation of OFL and the removal of conventional pollutants.
