A novel annexin dimer targets microglial phagocytosis of astrocytes to protect the brain-blood barrier after cerebral ischemia.

Despite the vital role of astrocytes in preserving blood-brain barrier (BBB) integrity, their therapeutic potential as targets in ischemic stroke-induced barrier disruption remains underexplored. We previously reported externalization of phosphatidylserine (PS) on astrocytic membranes concurrent with the emergence of PS externalization in neurons. PS externalization of astrocytes induced microglial phagocytosis of astrocytes, resulting in reduced astrocyte-vascular coupling and subsequent BBB breakdown.

Association of Di(2-ethylhexyl) Phthalate Exposure with Reproductive Hormones in the General Population and the Susceptible Population: A Systematic Review and Meta-Analysis.

Di(2-ethylhexyl) phthalate (DEHP), an environmental endocrine disruptor, has hormone-like activity and endocrine-disrupting effects. However, the types of reproductive hormones associated with DEHP vary across the studies. Thus, we conducted a systematic review and meta-analysis to pool existing epidemiological evidence.

Halide-Diffusion-Assisted Perovskite Lamination Process for Semitransparent Perovskite Solar Cells.

Semitransparent perovskite solar cells (PSCs) efficiently absorb light from both front and rear sides under illumination, and hence, PSCs have the potential for use in applications requiring bifacial or tandem solar cells. A facile method to fabricate semitransparent PSCs involves preparing a perovskite (PVSK) film on two transparent substrates and then laminating the substrates together. However, realizing high-performance laminated semitransparent PSCs is challenging because the imperfect contact at the PVSK interlayer results in void formation and partial degradation of PVSK.

Choroid plexus CCL2‒CCR2 signaling orchestrates macrophage recruitment and cerebrospinal fluid hypersecretion in hydrocephalus.

The choroid plexus (ChP) serves as the principal origin of cerebrospinal fluid (CSF). CSF hypersecretion due to ChP inflammation has emerged as an important pathogenesis of hydrocephalus recently. Nevertheless, the precise mechanisms of ChP inflammation and the ensuing CSF hypersecretion in hydrocephalus remain ill-defined.

This study aimed to assess the survival benefit of pTACE for HCC patients with CP B.

Methods: Data from 297 HCC patients with CP B7 or B8 were analyzed, dividing them into groups with and without pTACE (70, 23.

Exceptional heatwaves and mortality in Europe: Greater impacts since the coronavirus disease 2019 outbreak.

Record-breaking hot weather (exceptional heatwaves) has been increasingly common worldwide, posing a significant threat to human health. However, little is known about the effect of these exceptional heatwaves on mortality in Europe, especially since the coronavirus disease 2019 (COVID-19) outbreak, which converges with climate change to affect healthcare systems and human lives. We collected mortality data of 967 regions in 30 European countries over the last decade (2014-2023) from the Eurostat.

Hierarchical Nanostructures CuBiO Integrated with Polyaniline Nanofibrous for Boosting Hole Extraction in Carbon-Based Perovskite Solar Cells.

Toward commercialization of carbon-based perovskite solar cells (C-PSCs), it is crucial to innovatively design inorganic hole transport layer materials that excel in extracting and transporting charge carriers to promote their photoelectric conversion efficiency (PCE). In this work, a novel and high-connectivity CuBiO-polyaniline nanofibrous (CuBiO-PN) reticular structure is created by integrating CuBiO hierarchical microspheres (CuBiO MS) with polyaniline nanofibrous. The introduction of CuBiO-PN as a hole transport layer (HTL) notably enhances the contact quality of the devices and substantially reduces the surface defects of C-PSCs.

Impact of hot and cold nights on pneumonia hospitalisations in children under five years: Evidence from low-, middle-, and high-income countries.

Background: Studies have shown that abnormal temperature at night is a risk factor for respiratory health. However, there is limited evidence on the impact of hot and cold nights on cause-specific diseases such as pneumonia, which is a leading cause of morbidity and mortality in children.

Forecasting influenza epidemics in China using transmission dynamic model with absolute humidity.

Background: An influenza forecasting system is critical to influenza epidemic preparedness. Low temperature has long been recognized as a condition favoring influenza epidemic, yet it fails to justify the summer influenza peak in tropics/subtropics. Recent studies have suggested that absolute humidity (AH) had a U-shape relationship with influenza survival and transmission across climate zones, indicating that a unified influenza forecasting system could be established for China with various climate conditions.

CT perfusion parameter estimation in stroke using neural network with transformer and physical model priors.

Objectives: CT perfusion (CTP) imaging is vital in treating acute ischemic stroke by identifying salvageable tissue and the infarcted core. CTP images allow quantitative estimation of CT perfusion parameters, which can provide information on the degree of tissue hypoperfusion and its salvage potential. Traditional methods for estimating perfusion parameters, such as singular value decomposition (SVD) and its variations, are known to be sensitive to noise and inaccuracies in the arterial input function.

Ion adsorption-enrichment effect and its driving mechanism for nano-dots lithography with SPM probe on water-soluble crystal surfaces.

Hypothesis: Water-soluble KDP (KHPO) crystals possess excellent optical properties and are employed as frequency converters in clean fusion energy. To improve their performances, there is an immediate necessity to lithograph surface nano-patterns on them. Although the Scanning Probe Microscope (SPM) provides a promising way to achieve this purpose through the water menisci, the driving mechanisms of the lithographic behaviors have not yet been revealed.
