Thermally evaporated perovskite light-emitting diodes (PeLEDs) hold great promise for high-quality display applications due to their exceptional large-area uniformity and ease of pixelation and integration. Beyond efficiency considerations, display technologies demanded exceptionally high luminance performance from LEDs. While the brightness of blue and green PeLEDs had progressed rapidly, the performance of red PeLEDs lagged significantly.

Natural resorbable collagen membranes are widely used in guided bone regeneration (GBR) in oral implantology and prosthodontics. However, the rapid degradation and inadequate mechanical properties raise concerns about potentially compromising the ultimate bone regeneration efficacy. In this study, we developed a novel GBR membrane by coating a urinary bladder matrix (UBM) onto small intestinal submucosa (SIS), a commonly used acellular material, to improve the cell-barrier and bone-regeneration performances.

The interplay between cancer-associated fibroblasts (CAFs) and extracellular matrix (ECM) mediates progress, metastasis, and therapy resistance. However, strategy of targeting ECM remodeling to enhance chemosensitivity in ovarian cancer remains elusive. Here, a 22-gene matrisome signature predicts chemotherapy response and survival in ovarian cancer.

Maxillofacial injuries that may cause severe functional and aesthetic damage require effective and immediate management due to continuous exposure to diverse microbial populations. Moreover, drug resistance, biofilm formation, and oxidative stress significantly impede timely bacterial removal and immune function, making the exploration of advanced materials for maxillofacial wound healing an appealing yet highly challenging task. Herein, a near-infrared photothermal sterilization agent was designed, encapsulated with liposomes and coated with ascorbic acid known for its antioxidant and immune-regulatory functions.

Closely related species often use the same genes to adapt to similar environments. However, we know little about why such genes possess increased adaptive potential and whether this is conserved across deeper evolutionary lineages. Adaptation to climate presents a natural laboratory to test these ideas, as even distantly related species must contend with similar stresses.

Article Synopsis
  • The study investigates the role of mitochondrial dysfunction in intrahepatic cholangiocarcinoma (iCCA), noting its underexplored significance in cancer biology.
  • Researchers collected and analyzed RNA sequencing data from multiple cohorts to develop a mitochondrial signature for assessing iCCA prognosis, using advanced genetic analysis methods.
  • The findings revealed 263 mitochondria-related genes linked to crucial processes like fatty acid metabolism and apoptosis, leading to the establishment of a five-gene signature that effectively predicts patient outcomes and reflects immune response levels.

Addressing fracture-related infections (FRI) and impaired bone healing remains a significant challenge in orthopedics and stomatology. Researchers aim to address this issue by utilizing biodegradable biomaterials, such as magnesium/poly lactic acid (Mg/PLA) composites, to offer antibacterial properties during the degradation of biodegradable implants. Existing Mg/PLA composites often lack sufficient Mg content, hindering their ability to achieve the desired antibacterial effect.

Understanding the genetic basis of how plants defend against pathogens is important to monitor and maintain resilient tree populations. Swiss needle cast (SNC) and Rhabdocline needle cast (RNC) epidemics are responsible for major damage of forest ecosystems in North America. Here we investigate the genetic architecture of tolerance and resistance to needle cast diseases in Douglas-fir (Pseudotsuga menziesii) caused by two fungal pathogens: SNC caused by Nothophaeocryptopus gaeumannii, and RNC caused by Rhabdocline pseudotsugae.

Article Synopsis
  • Plum (Lindl.) is a nutrient-rich fruit cultivated globally but is facing severe anthracnose outbreaks in parts of China, leading to damaged leaves and premature fall.
  • In a study, anthracnose samples were collected from various regions in Guangxi and Sichuan Provinces, involving analysis of mycelia characteristics and genetic sequencing.
  • The findings identified 101 isolates belonging to eight different species of pathogens, with eight species confirmed to cause disease in plum seedlings, marking the first report of two specific species causing anthracnose in China.

Background: According to statistics, ovarian cancer (OV) is the most prevalent type of gynecologic malignancy and has the highest mortality rate of all gynecologic tumors. Although several studies have shown that oxidative stress (OS) contributes significantly to the onset and progression of cancer, the role of OS in OV needs to be investigated further. Thus, it is critical to comprehend the function of OS-related genes in OV.

Methods using genomic information to forecast potential population maladaptation to climate change or new environments are becoming increasingly common, yet the lack of model validation poses serious hurdles toward their incorporation into management and policy. Here, we compare the validation of maladaptation estimates derived from two methods-Gradient Forests (GF) and the risk of non-adaptedness (RONA)-using exome capture pool-seq data from 35 to 39 populations across three conifer taxa: two Douglas-fir varieties and jack pine. We evaluate sensitivity of these algorithms to the source of input loci (markers selected from genotype-environment associations [GEA] or those selected at random).

  • Biochar, when activated with KOH or NaOH, shows improved effectiveness in removing NO, but the mechanism for NaOH is not fully understood.
  • Density functional theory (DFT) was used to study how lithium (Li) and sodium (Na) interact with biochar, finding that their adsorption lowers the energy required for NO reduction reactions.
  • Li-activated biochar outperformed Na-activated biochar in NO removal due to a lower reaction barrier, while the presence of OH groups also participated effectively in the reduction process.

Backgrounds And Aims: Immunotherapies have formed an entirely new treatment paradigm for hepatocellular carcinoma (HCC). Tertiary lymphoid structure (TLS) has been associated with good response to immunotherapy in most solid tumors. Nonetheless, the role of TLS in human HCC remains controversial, and recent studies suggest that their functional heterogeneity may relate to different locations within the tumor.

Commercially available guided bone regeneration (GBR) membranes often exhibit limited mechanical properties or bioactivity, leading to poor performance in repairing bone defects. To surmount this limitation, we developed a Janus structural composite membrane (Mg-MgO/PCL) reinforced by dual Mg (Mg sheets and MgO NPs) by using a combined processing technique involving casting and electrospinning. Results showed that the addition of Mg sheets and MgO NPs enhanced the mechanical properties of the composite membrane for osteogenic space maintenance, specifically tensile strength (from 10.

The assessment of early atherosclerosis (AS) is of great significance for the early diagnosis and mechanism research. Herein, a novel nanoprobe PCN@FL is developed to realize the simultaneous detection and imaging of phosphorylation and hypochlorous acid (HClO). The selective recognition of HClO is achieved through the specific interaction between DMTC and HClO, while the levels of phosphorylation are detected via the specific interaction between Zr (IV) and phosphates.

Background: Even after curative resection, the prognosis for patients with intrahepatic cholangiocarcinoma (iCCA) remains disappointing due to the extremely high incidence of postoperative recurrence.

Methods: A total of 280 iCCA patients following curative hepatectomy from three independent institutions were recruited to establish the retrospective multicenter cohort study. The very early recurrence (VER) of iCCA was defined as the appearance of recurrence within 6 months.
