Blue phase liquid crystal (BPLC) lasers exhibit exceptional optical quality and tunability to external stimuli, holding significant promise for innovative developments in the field of flexible optoelectronics. However, there remain challenges for BPLC elastomer (BPLCE) lasers in maintaining good optical stability during stretching and varying temperature conditions. In this work, a stretchable laser is developed based on a well-designed BPLCE with a combination of partially and fully crosslinked networks, which can output a single-peak laser under small deformation (44.

Recent progress in wound healing has highlighted the need for more effective treatment strategies capable of addressing the complex biological and physiological challenges of wound repair. Traditional wound dressings often fail to address the complex and evolving needs of chronic, acute, and burn wounds, particularly in terms of promoting healing, preventing infection, and supporting tissue regeneration. In response to these challenges, calcium alginate fibers (CAFs) have emerged as promising materials, characterized by their exceptional structural properties and diverse biological functions, offering significant commercial potential for the development of advanced wound dressings and therapeutic solutions.

Triterpenoids are the major active constituents of licorice, a well-known traditional medicinal herb. Licorice triterpenoids, represented by glycyrrhizin and glycyrrhetic acid, have a high structural diversity and are excellent lead compounds for the development of potent pharmaceuticals. However, their further application can be limited by insufficient activities, low bioavailability, and the presence of side effects, as well as the inefficiency of traditional plant extraction processes for compound production.

Blue phase liquid crystals (BPLCs) have exhibited promising applications in 3D flexible displays due to their molecular-level self-assembled chiral structures, fast response, and tunable polarized colors. However, there remain challenges for spatiotemporal programming of 3D chiral color units for BPLC dynamic patterning. Herein, the programmable temporal evolution of micrometer-scale color units and spatial configuration switch of chiral modes are achieved by spontaneous ink diffusion-driven asymmetric lattice deformation in dual-chiral polymer-templated blue phases.

Background: Accumulation of senescent cells in tissues and their downstream effect programs have emerged as key drivers of aging and age-associated pathologies. Recent progresses in senotherapeutics indicated that either selectively killing senescent cells with senolytics or suppressing the senescence-associated secretory phenotype (SASP) secretion using senomorphics contributes to extending of the healthy lifespan and alleviating numerous age-related disorders in mice.

Purpose: However, the potential side-effects and long-term cytotoxicity of the above novel compounds have not yet been determined.

This paper investigates the aeration and oxygen transfer characteristics within the aeration tank of an integrated wastewater treatment system (IWTS) using Computational Fluid Dynamics coupled with Population Balance Model and oxygen transfer model. The findings suggest that increasing the air flow rate significantly enhances the oxygen transfer rate, albeit at a decreasing rate of growth. The oxygen overall mass transfer coefficient is primarily influenced by the interfacial area per unit volume and to a lesser by the oxygen mass transfer coefficient (k).

  • Senescent cells are non-dividing cells associated with skin aging due to a specific secretory phenotype, but understanding skin aging has been limited by a lack of identified markers.
  • Recent research indicates that intracellular calcium signaling is important in regulating cellular senescence, especially in skin keratinocytes, although its exact roles are still not fully understood.
  • This study developed a model of skin keratinocyte senescence using ionizing radiation and found that inhibiting the calcium-related gene TGM2 can delay senescence by reducing calcium signaling, oxidative stress, DNA damage, and inflammatory secretions.

Intracerebral hemorrhage has the characteristics of high morbidity, disability and mortality, which has caused a heavy burden to families and society. Microglia are resident immune cells in the central nervous system, and their activation plays a dual role in tissue damage after intracerebral hemorrhage. The damage in cerebral hemorrhage is embodied in the following aspects: releasing inflammatory factors and inflammatory mediators, triggering programmed cell death, producing glutamate induced excitotoxicity, and destroying blood-brain barrier; The protective effect is reflected in the phagocytosis and clearance of harmful substances by microglia, and the secretion of anti-inflammatory and neurotrophic factors.
