The growing impact of climate change and escalating wildfire seasons has led to heightened ambient air pollution, potentially affecting children's sleep health. However, current epidemiological research often relies on outdoor weather data to model the environmental impacts on sleep health, potentially mischaracterizing the actual bedroom environment. To address these challenges, we conducted experiments to investigate the relationships among ambient, indoor, and personal exposure to PM concentrations and obstructive sleep apnea (OSA) in children.

Tissue engineering and in vitro modeling of the airways and lungs in the respiratory system are of substantial research and clinical importance. In vitro airway and lung models aim to improve treatment options for airway and lung repair and advance respiratory pathophysiological research. The construction of biomimetic native airways and lungs with tissue-specific biological, mechanical, and configurable features remains challenging.

Aerosol acidity, defined as pH, is a critical property that influences the formation, evolution, and health and climate effects of atmospheric aerosol particles. Direct measurement of ambient aerosol pH, however, remains challenging for atmospheric scientists. Here, based on the method of colorimetric analysis on aerosol-loaded pH-indicator papers, we develop a new device that can achieve in situ and real-time measurement of the pH of ambient aerosol droplets at a fixed relative humidity of 90%.

Basic amino acid alternating copolymers exhibit exceptional antimicrobial properties and biosafety, yet their application is restricted by the complexity of the synthesis process and low molecular weight ( = 1000). In this study, we synthesized a basic amino acid alternating copolymer (Orn-Val) in only one step by the Ugi four-component condensation (Ugi'4CC), achieving high molecular weight ( = 20,000) and narrow polydispersity (PDI ≤ 1.10).

Smart fibers capable of integrating the multifunctionality of actuation and self-sensation into a single proprioceptive device have significant applications in soft robots and biomedicine. Especially, the achievement of self-sensing the movement patterns of different actuating segments in one fiber is still a great challenge. Herein, in this study, a fiber with the controllable Janus architecture is successfully proposed via an artful centrifugation-driven hierarchical gradient self-assembly strategy, which couples two functional components of piezoresistive carbon nanotubes and magnetic NdFeB nanoparticles into the upper and lower layers of this flexible fibrous framework with the porous sponge structure partially, respectively.

Article Synopsis
  • Foodborne pathogens like E. coli and Staphylococcus aureus pose significant health risks and economic losses, highlighting the need for effective detection methods due to the limitations of traditional techniques.* -
  • This study introduces a novel fluorescent biosensor using bacteria-instructed atom transfer radical polymerization (ATRP), enhancing detection sensitivity and specificity for these pathogens by initiating polymer growth in response to bacterial activity.* -
  • The biosensor demonstrates a strong linear correlation between fluorescence intensity and bacterial concentrations, achieving detection limits as low as 10 CFU/mL, making it a promising tool for direct pathogen detection without complex equipment.*

Article Synopsis
  • Phagocytosis of photoreceptor outer segments by retinal pigment epithelium (RPE) cells is vital for maintaining retinal health, and disruption in this process can lead to severe retinal diseases.
  • The research identifies CYLD, a deubiquitinase, as a key player in the phagocytic process, where its deficiency leads to abnormal retinal structure and function in mice.
  • The study reveals that CYLD interacts with ENKD1, helping to stabilize Ezrin, which is necessary for phagocytosis in RPE cells, highlighting the potential for targeted therapies in retinal degenerative conditions.

  • The auxin response factor (ARF) is crucial for regulating plant growth and stress response by binding to auxin response gene promoters; however, specific roles in Fagopyrum dibotrys remain unclear.
  • A study identified 26 FdARF genes, analyzing their chromosomal distribution, gene structures, and protein properties, revealing a predominant presence on chromosome 4 and varying subcellular localizations.
  • Expression profiling showed these genes are predominantly active in different plant tissues and respond differentially to abiotic stress, suggesting FdARFs play a significant role in the plant's stress response.

Disordered glucose and lipid metabolism, coupled with disturbed mitochondrial bioenergetics, are pivotal in the initiation and development of diabetic kidney disease (DKD). While the essential role of telomerase reverse transcriptase (TERT) in regulating mitochondrial function in the cardiovascular system has been recognized, its specific function in maintaining mitochondrial homeostasis in DKD remains unclear. This study aimed to explore how TERT regulates mitochondrial function and the underlying mechanisms.

Naive pluripotent stem cells have the highest developmental potential but their in vivo existence in the blastocyst is transient. Here we report a blastocyst motif substrate for the in vitro reversion of mouse and human pluripotent stem cells to a naive state. The substrate features randomly varied microstructures, which we call motifs, mimicking the geometry of the blastocyst.
