This study examined the association between serum uric acid levels (SUA) and arterial stiffness in patients with psoriasis vulgaris. A cross-sectional study was conducted on 205 consecutive patients with psoriasis vulgaris who visited the Dermatology Clinic of China-Japan Friendship Hospital between March 2022 and July 2024. Arterial stiffness was assessed by measuring brachial-ankle pulse wave velocity (baPWV).

Article Synopsis
  • A study examined the effects of opioid use in breast cancer survivors after treatment, comparing them with age-matched women without cancer, focusing on health risks.
  • The results showed that breast cancer survivors used more opioids and had a higher risk of falls, fractures, lung problems, and cardiovascular events compared to non-users.
  • The findings highlight the need for careful monitoring of opioid prescriptions in breast cancer survivors and the importance of exploring alternative pain management strategies.

  • A study evaluated the participation rates of the Kaiser Permanente Side Effect Monitor (KPSEM), a self-reporting system for vaccine side effects, among patients receiving COVID-19 vaccinations from April 2021 to July 2023.
  • Out of over 2 million vaccinated patients, only about 8% participated, with significant variations based on age and race; younger parents had the lowest rates, while older adults participated the most.
  • The findings indicate that socio-economic factors influenced participation, as individuals in lower deprivation areas and certain racial groups were less likely to engage with the system.

Article Synopsis
  • Aberrant energy metabolism, particularly glycolysis in astrocytes, is identified as a significant feature in the early stages of Alzheimer's Disease (AD), potentially impacting cognitive function.
  • Research shows that Aβ-activated microglia enhance astrocyte glycolysis through the AKT-mTOR-HIF-1α pathway, which contributes to cognitive deficits in early AD by disrupting synaptic functions and increasing Aβ aggregation.
  • The use of rapamycin, an mTOR inhibitor, shows promise in reversing spatial memory impairment and reducing Aβ levels by targeting the excess L-lactate produced from increased glycolysis in astrocytes, suggesting a potential therapeutic approach for AD.

Article Synopsis
  • Scientists created a new type of detector for positron emission tomography (PET) scanners that makes it easier to find where gamma photons interact.
  • The new design mixes different types of sensors to improve the way these interactions are measured without needing complicated instructions.
  • Tests showed that this hybrid detector can accurately identify the positions of events and has fast timing, making it more efficient and easier to use than older models.

Purpose: To quantify the presence of early structural alterations in the outer retinal layer and choroid among healthy subjects and diabetic patients with no or mild diabetic retinopathy, and to establish the correlation between the measured structural parameters and retinal sensitivity.

Methods: In total, 31 eyes from subjects with type 2 diabetes and 29 eyes from healthy subjects were enrolled. Optical coherence tomography was used to measure outer retina layers and choroid, while microperimetry was used to characterize the changes of visual function in a 6-mm diameter area at macula.

Article Synopsis
  • The proposed design features a multi-resolution detector using two layers of LYSO crystals, targeting enhanced spatial, depth-of-interaction (DOI), and time-of-flight (TOF) resolutions for PET scanners focused on human brain imaging.
  • The top layer employs a smaller crystal array for high spatial resolution, while the bottom layer uses larger crystals to achieve improved TOF resolution, with inter-crystal light sharing enhancing DOI resolution.
  • The system demonstrates impressive performance, with high accuracy in distinguishing crystal layers and optimizing coincidence time resolution, making it ideal for next-generation brain-dedicated PET technology.

Purpose: Uterine cancer risk is high in breast cancer survivors. Although breast cancer and uterine cancer share some common epidemiological risk factors, association of metabolic syndrome with incident uterine cancer in breast cancer survivors is under-studied. We evaluated the association of metabolic syndrome conditions with second primary uterine cancer in breast cancer survivors.

Mild cognitive impairment (MCI) is a critical transitional stage between normal cognition and dementia, for which early detection is crucial for timely intervention. Retinal imaging has been shown as a promising potential biomarker for MCI. This study aimed to develop a dual-stream attention neural network to classify individuals with MCI based on multi-modal retinal images.

Legume crops such as soybean obtain a large portion of their nitrogen nutrition through symbiotic nitrogen fixation by diazotrophic rhizobia bacteria in root nodules. However, nodule occupancy by low-capacity nitrogen-fixing rhizobia can lead to lower-than-optimal levels of nitrogen fixation. Seed/root coating with engineered materials such as graphene-carrying biomolecules that may promote specific attraction/attachment of desirable bacterial strains is a potential strategy that can help overcome this rhizobia competition problem.

By constructing nanofluid system, trace functionalized nanoparticles can significantly enhance the absorption performance of basic liquid. In this work, amino functionalized carbon nanotubes (ACNTs) and carbon nanotubes (CNTs) were introduced into alkaline deep eutectic solvents to build nanofluid systems and used for the dynamic absorption of HS. The experiment results showed that the introduction of nanoparticles can significantly enhance the HS removal performance of original liquid.

Article Synopsis
  • Electromagnetic source imaging (ESI) faces challenges due to its ill-posed nature, often relying on imprecise priors that limit its effectiveness.
  • A new method called data-synthesized spatiotemporally convolutional encoder-decoder network (DST-CedNet) is introduced, treating ESI as a machine learning issue by leveraging discriminative learning and latent-space representations.
  • By using a unique data synthesis strategy that incorporates knowledge about brain activity, DST-CedNet generates large datasets for better training, significantly outperforming traditional ESI methods in accurately estimating brain source signals based on various datasets.

An optimized "rigid-flexible" structure with multistage gradient modulus was constructed on carbon fiber (CF) surface via chemical grafting using "flexible" polyethyleneimine (PEI) and "rigid" polydopamine (PDA) between "rigid" CF and "flexible" epoxy (EP) to elaborate a double alternant "rigid-flexible" structure for simultaneously strengthening and toughening CF/EP composites. PDA and PEI polymers can greatly enhance the roughness and wettability of CF surfaces, further strengthening the mechanical interlocking and chemical interactions between CFs and epoxy. Besides, the "rigid-flexible" structure endows the interface with a gradient transition modulus, which could uniformly transfer internal stress and effectively avoid the stress concentration.
