Unlabelled: While previous research has established correlations between pre-pregnancy body mass index (BMI), late-pregnancy blood glucose, and late-pregnancy blood lipid levels during pregnancy and offspring's physical development, the underlying mechanism of their interaction remains elusive. A birth cohort study was conducted on pregnant women, who are biologically female, delivering at a tertiary hospital in Wuhan City between May 2023 and April 2024, encompassing 1620 participants. We collected maternal socio-demographic data through questionnaires and obtained information on fasting blood glucose (FPG), lipid levels during the third trimester, and neonatal physical development from medical records.

The rapid development of visual neuromorphic hardware can be attributed to their ability to capture, store and process optical signals from the environment. The main limitation of existing visual neuromorphic hardware is that the realization of complex functions is premised on the increase of manufacturing cost, hardware volume and energy consumption. In this study, we demonstrated an optical synaptic device based on a three-terminal van der Waals (vdW) heterojunction that can realize the sensing functions of light wavelength and intensity as well as short-term and long-term synaptic plasticity.

Objective: To investigate the potential of composite inflammatory markers, including the neutrophil-to-lymphocyte ratio (NLR), in predicting outcomes in patients with posterior circulation large vessel occlusion who underwent mechanical thrombectomy (MT).

Methods: We included patients who underwent MT for posterior circulation large vessel occlusion between February 2016 and December 2021. We then assessed composite inflammatory markers on day 1 post-MT.

Article Synopsis
  • Bisphenol A (BPA) is a chemical linked to health issues, particularly affecting thyroid function during the vulnerable period of pregnancy due to changing hormone levels.
  • A systematic review analyzed 11 studies involving over 6,500 pregnant women to assess the relationship between BPA exposure and thyroid hormone levels using established evaluation methods.
  • The findings suggest that BPA exposure may disrupt maternal thyroid hormones and increase the risk of hyperthyroidism, indicating a need for further research to understand the mechanisms involved.

Ischemic stroke (IS) remains a serious threat to human health. Neuroinflammatory response is an important pathophysiological process after IS. Circular RNAs (circRNAs), a member of the non-coding RNA family, are highly expressed in the central nervous system and widely involved in regulating physiological and pathophysiological processes.

Human milk (HM) is a proven optimal food for preterm infants. However, there is uncertainty regarding the effects of different proportions of HM of the total enteral intake on health outcomes in preterm infants. Therefore, we conducted a systematic review of studies examining the effects of different proportions of HM of the total enteral intake on health outcomes in preterm infants.

Atherosclerosis (AS) is a disease dangerous to human health and the main pathological cause of ischemic cardiovascular diseases. Although its pathogenesis is not fully understood, numerous basic and clinical studies have shown that AS is a chronic inflammatory disease existing in all stages of atherogenesis. It may be a common link or pathway in the pathogenesis of multiple atherogenic factors.

Ischemic stroke (IS) is a severe disease with a high disability, recurrence, and mortality rates. Autophagy, a highly conserved process that degrades damaged or aging organelles and excess cellular components to maintain homeostasis, is activated during IS. It influences the blood-brain barrier integrity and regulates apoptosis.

In this study, a simple and effective coating method to improve printing quality and material utilization rate was proposed. The flow behavior of pico-liter scale ink droplets on the silk fabric surfaces which treated separately with Sodium alginate (SA), Hydroxyethyl cellulose (HEC) and Hydroxyethyl methyl cellulose (HEMC) was observed and measured. Indeed, based on the direct empirical results, the optimal pretreatment process on the fabrics, aiming to increase the ink utilization rate and further improve the surface printing clarity, has been obtained in the experiments.

As an important approach of distributed artificial intelligence, multi-agent system provides an efficient way to solve large-scale computational problems through high-parallelism processing with nonlinear interactions between the agents. However, the huge capacity and complex distribution of the individual agents make it difficult for efficient hardware construction. Here, we propose and demonstrate a multi-agent hardware system that deploys distributed Ag nanoclusters as physical agents and their electrochemical dissolution, growth and evolution dynamics under electric field for high-parallelism exploration of the solution space.

The recent advances in optic neuromorphic devices have led to a subsequent rise in use for construction of energy-efficient artificial-vision systems. The widespread use can be attributed to their ability to capture, store, and process visual information from the environment. The primary limitations of existing optic neuromorphic devices include nonlinear weight updates, cross-talk issues, and silicon process incompatibility.

Dynamic physical systems such as reservoir computing (RC) architectures show a great prospect in temporal information processing, whereas hierarchical information processing capability is still lacking due to the absence of advanced multilayer reservoir elements. Here, a stackable reservoir system is constructed based on ferroelectric α-In Se devices with voltage input and output, which is realized by dynamic voltage division between a ferroelectric field-effect transistor and a planar device and therefore allows the reservoirs to cascade, enabling multilayer RC. Fast Fourier transformation analysis shows high-harmonic generation in the first layer as a result of inherent nonlinearity of the reservoir, and progressive low-pass filtering effect is realized where higher-frequency components are progressively filtered in deeper-layer RCs.
