The tumor suppressor p53 can trigger tumor resistance to chemotherapy by facilitating DNA damage repair and maintaining genomic integrity. Here, we report that a p53-induced circular RNA circASCC3 promotes chemotherapeutic resistance by resolving R-loops. Our results reveal that p53 directly activates the transcription of , the host gene of circASCC3.

Sitafloxacin is a quinolone broad-spectrum antimicrobial agent, and its pharmacologic properties and data demonstrate that sitafloxacin has a potent killing effect against , including drug-resistant strains, which is superior to that of other available quinolones. However, its efficacy in patients with primary-sensitive tuberculosis is unclear. This study aims to evaluate the early bactericidal activity (EBA) of sitafloxacin in patients with primary drug-susceptible tuberculosis.

Although p53 regulates glycolytic metabolism, its role in cuproptosis remains unclear. Here, we report that the circular RNA, circFRMD4A, is crucial for p53-mediated metabolic reprogramming and cuproptosis.

In carbon-based supercapacitors, redox couples can effectively improve the energy density of supercapacitors; however, most redox couples still suffer from serious shuttle diffusion. Currently, there is no universal strategy to effectively constrain their shuttle diffusion. Therefore, developing a simple, effective, and universal method to suppress shuttle diffusion remains a great challenge.

The technique is popularly employed in Chinese chive (CC). Blanched Chinese chive (BCC) is renowned for its pale-yellow appearance, delicate flavor, and culinary-medicinal values; nonetheless, how blanching alters the chemical composition largely remains intangible.

Targeted blockade of ribosome biogenesis induces nucleolar stress, which preferentially leads to the elimination of malignant cells. In this study, it is reported that the nucleolar protein BRIX1 is a critical regulator for the homeostasis between ribosome biogenesis and p53 activation.

Methods: The contents of 14 OPEs and 7 metabolites in drinking water were determined by automatic solid phase extraction, isotope dilution and liquid chromatography tandem mass spectrometry. The average daily potential dose(ADD) were calculated based on the recommended intake of drinking water.
Objective: To understand the current status of occupational stress, occupational burn-out and sleep quality among ambulance drivers in Hengyang, China and to analyse the relationship between occupational stress, occupational burn-out and sleep quality of ambulance drivers.
Design: A cross-sectional study.
Setting: Prehospital emergency centre of third-class hospital in Hengyang, China.
Ascorbic acid (AsA) is an essential nutritional component and powerful antioxidant in vegetables, and in plants, AsA levels are regulated by light. AsA levels in the leaves of Chinese chive (Allium tuberosum Rottler ex Spr), a popular vegetable, are poorly understood. Thus, this study was performed to assess the influence of light on AsA biosynthesis in chive and select related genes (AtuGGP1 and AtuGME1); in addition, bioinformatic analyses and gene expression level assays were performed.

In this study, we utilized methylated RNA immunoprecipitation sequencing (MeRIP-seq) and RNA sequencing (RNA-seq) to identify m1A peaks and the expression profile of mRNA in the decidua of humans with early-onset PE (EPE), late-onset PE (LPE), and normal pregnancy (NP). We assessed the m1A modification patterns in preeclamptic decidua using 10 m1A modulators.

Background: The rise in e-cigarette use among youth is a significant global public health issue. It is important to identify those at increased risk and implement effective strategies to reduce e-cigarette popularity among the youth.
Objective: This study aims to identify predictors of e-cigarette uptake in youths with no prior tobacco use, considering individual, familial and the broader societal environmental factors.
In this study, we reported the discovery and structure-activity relationship analysis of chrysin derivatives as a new class of inhibitors targeting poly (ADP-ribose) polymerase 1 (PARP1). Among these derivatives, compound 5d emerged as the most effective chrysin-based inhibitor of PARP1, with an IC value of 108 nmol·L. This compound significantly inhibited the proliferation and migration of breast cancer cell lines HCC-1937 and MDA-MB-436 by inducing DNA damage.

The senescence-associated secretory phenotype (SASP) is a critical source of inflammation factors. However, the molecular mechanism by which the SASP is regulated in ECs under ox-LDL conditions remains unknown.

Methods: A total of 187 patients who underwent posterior spinal surgery were enrolled and randomly divided into 3 groups: 61 in the volume-controlled ventilation (VCV) group (group V), 62 in the PCV-volume-guaranteed (VG) group (group P), and 64 in the PCV-VG end-expiratory zero flow rate group (group P). Indicators including tidal volume (V), peak airway pressure (P), and dynamic lung compliance (Cdyn) were recorded.
Introduction: The aim of this study was to investigate the causal relationship between Parkinson's disease (PD) and myocardial infarction (MI), atrial fibrillation and flutter (AF), and venous thromboembolism (VTE) by Mendelian randomization (MR) analysis.
Methods: By using data from publicly available genome-wide association studies from databases, single nucleotide polymorphisms were screened as instrumental variables, and the MR analysis was finished by inverse-variance weighted (IVW), MR-egger, weighted median methods.
Results: The primary IVW method showed a negative association between genetically predicted PD and risk of MI (OR = 0.
Purpose: The purpose of this study was to explore the relationship between education level and health behavior including sleep, work activity, exercise activity, and sedentary behavior among emerging adults.
