Background: Ferroptosis is an intracellular iron-dependent cell death that is distinct from apoptosis, necrosis, and autophagy. Increasing evidence indicated that ferroptosis plays a crucial role in suppressing tumors, thus providing new opportunities for cancer therapy. The drug cepharanthine, commonly used to treat leukopenia, has been discovered to function as an anticancer agent to multiple types of cancer via diverse mechanisms.

However, lacking of precise and noninvasive tracers for fibrotic lesions limits timely diagnosis and treatment. Here, we identified LyP-1, a cyclic peptide, as a specific and sensitive tracer for PF detection using PET/CT imaging.

Results: The average age of the 4 patients was (57.
Obesity arises from chronic energy imbalance where energy intake exceeds energy expenditure. Emerging evidence supports a key role of DNA methylation in the regulation of adipose tissue development and metabolism. We recently discovered a key role of DNA methylation, catalyzed by DNA methyltransferase 1 or 3a (Dnmt1 or 3a), in the regulation of adipocyte differentiation and metabolism.

It expands the boundaries of technology acceptance research by focusing on ICS use and avoidance in high-risk environments.
Method: A total of 418 valid questionnaires were collected from participants, ensuring data quality through rigorous screening.
Wind turbine blade deformation affects the ability of the blade to capture wind energy, and the dynamic deformation law of the actual wind turbine blade is unclear. This study constructs a wind turbine blade dynamic deformation measurement system based on DIC, investigates the blade dynamic deformation regularity, and fits a polynomial to predict the blade dynamic wave deformation. The results show that the modulus of elasticity of the blade determines the time required to calm the fluctuation after deformation, and the length of this time is negatively correlated with the modulus of elasticity of the blade.

By training monkeys to perform heterogeneous saccade sequences, we investigated the role of the dorsolateral prefrontal cortex (DLPFC) and the lateral intraparietal cortex (LIP) in sequence planning and execution. The electrophysiological recording revealed that sequence-level initiation information was mostly signaled by DLPFC neurons, whereas subsequence-level transition was largely encoded by LIP neurons.

Accurately analyzing the type of land use and change characteristics of disaster damage in landslide areas is of great significance to scientifically promote the optimization of regional land use pattern and disaster prevention and mitigation. We analyzed the characteristic parameters of landslides as well as the characteristics and driving factors of land use change from 1985 to 2020 in Tongwei County, Gansu Province, using ALOS DEM data and 1985-2020 land use data, GIS spatial analysis, land-use dynamic attitude, transfer matrix, and Geodetector. The results showed that a total of 1012 landslide samples were identified, characterized by medium elevation, gentle gradient, low elevation difference, short length, and small size.

Utilizing a dataset from A-share listed companies in China from 2007 to 2021, this paper investigates the direct impact, underlying mechanism and driving effect of enterprise digital transformation on carbon emission intensity. The findings reveal that: (1) At this stage, digital transformation in listed companies effectively reduces their carbon intensity, but the relationship between the two is not linear; instead, it exhibits a U-shaped trajectory, initially decreasing then increasing.

Aims: To analyze the postoperative recovery effects of different internal fixations on intertrochanteric fractures, so as to select the best fixation method for clinical practice.
Methods: This is a retrospective analysis. A total of 100 patients with intertrochanteric fractures hospitalized at The Affiliated Tai'an City Central Hospital of Qingdao University from March 2022 to March 2024 were grouped according to the treatment method.
Understanding the mechanisms behind MYC-driven oncogenic transformation could pave the way for identifying novel drug targets. This study explored the role of CREPT in MYC-induced malignancy by generating MYC-transformed mouse embryonic fibroblasts (MEFs) with conditional CREPT deletion. Our results demonstrated that the loss of CREPT significantly impaired MYC-induced colony formation and cell proliferation, indicating that CREPT is essential for the malignant transformation of MEFs.
