Altitude and ecological factors significantly influence plant growth and the accumulation of secondary metabolites. However, current research on the impact of altitude and ecological factors on the yield and medicinal quality of is limited. This study established sampling sites in wild populations of across seven altitude ranges on Funiu Mountain.

Many intuitively perceive them as distinct measures and assume that they have a concave-down relationship. In everyday life, there is a common consensus that while entropy never decreases, complexity does decrease after an initial increase during the process of blending coffee and milk.

This study separately assessed ESSV and human disturbance in Guangxi from 1990 to 2020, revealing their spatiotemporal distribution differences over time. The environmental Kuznets curve (EKC) is used to analyze the interrelationship between the two, with the purpose of filling the gap in current research.

Volatile organic compounds (VOCs) have caused serious harm to human health and ecological environment, and have received much attention in recent years. Despite the successful applications of catalytic combustion of VOCs as the core technology of VOCs removal in industry, the development of efficient catalysts that can mineralize VOCs into nontoxic CO and HO at low temperatures remains a great challenge. Recent studies show that spinel-based materials as efficient catalysts were extensively used in the catalytic oxidation VOCs field due to their synergistic effect, manifold compositions, and electron configurations.

Design: A nationwide multicenter cohort study.
Setting And Participants: 8,831 inpatients aged 18 years and older, histologically diagnosed with cancer and receiving anti-cancer therapy.
Background: The intestinal tract, as the main place for nutrient digestion and absorption, is closely related to the health of livestock and poultry. Melatonin secreted by the pineal gland acts as an endocrine transport signaling molecule to regulate intestinal function. However, the effect on intestinal function after pineal removal is unclear.

Activated carbon fiber (ACF) is a fibrous activated carbon (AC) characterized by high specific surface area (SSA), abundant micropore structure, and excellent machinability, making it an ideal electrode material. This work provided a theoretical basis for the sustainable and large-scale production of high-performance ACF from natural cellulose through fibrillation treatment, papermaking techniques, and CO activation. The effect of fiber fibrillation degree on ACF's structure and electrochemical performance was investigated in detail.

In this cross-sectional study, we endeavored to indicate some key clinical and imaging features of neurosyphilis patients, particularly those specific to PPS.
Methods: We retrospectively included all syphilis patients enrolled in the study from January 2021 to February 2024.
In order to solve the problem that existing visible and infrared image fusion methods rely only on the original local or global information representation, which has the problem of edge blurring and non-protrusion of salient targets, this paper proposes a layered fusion method based on channel attention mechanism and improved Generative Adversarial Network (HFCA_GAN). Firstly, the infrared image and visible image are decomposed into a base layer and fine layer, respectively, by a guiding filter. Secondly, the visible light base layer is fused with the infrared image base layer by histogram mapping enhancement to improve the contour effect.

Estimating the RUL enables the assessment of health bearing, maintenance planning, and significant cost reduction, thereby fostering industrial development. Existing models rely on traditional feature engineering with feature changes because operating conditions pose a major challenge to the generalization of RUL prediction models.

Longitudinal leaky surface acoustic wave (LL-SAW) devices with unique advantages can be a promising platform. In this paper, we introduce a 100 nm intermediate oxide layer into the X-cut lithium niobate on silicon carbide (LiNbO/SiC) to improve the in-band performance of LL-SAW resonators.

Approximately one third of patients consistently experience drug-resistant epilepsy (DRE), a condition where seizures persist despite the use of antiseizure medications. Exploration of new therapies for DRE is urgently needed.

However, the relationship between GERD and blood pressure components, lipid profile, and cardiovascular diseases remains unclear.
Methods: Leveraging genetic variants associated with GERD as instrumental variables, we performed this Mendelian randomization (MR) analyses.
The dysfunction of gut microbiome and bile acid metabolism might cause the incidence and relapse of ulcerative colitis (UC). Thus, natural products have been considered effective for UC through the regulation of gut microbiome and bile acid. In this study, we evaluated the regulatory effect of berberine on gut microbiome and bile acid metabolism in UC.

Here, we reported a splice mutation in gene in the patient with recurrent epistaxis and nasal vascular malformation. The patient, an 8-year-old girl, suffered from anemia due to frequently severe recurrent epistaxis, requiring regular blood transfusions every 2-3 months.

The rapid development of digital intelligence technologies is providing a powerful boost to the high-quality development of the healthcare system. Considering the current state of our healthcare services and guided by General Secretary Xi Jinping's insights on new quality productive forces and the directives from Third Plenary Session of Communist Party of China's 20th Central Committee, the high-quality development of the healthcare service system should focus on digital intelligence technologies such as cloud computing, big data, privacy computing, blockchain, Internet of Things (IoT), mobile computing, and AI. The key measures should include the optimization of production factors, services, and governance.
