Sweet sorghum (Sorghum bicolor Moench) seedling emergence and growth are significantly impeded by physical soil crusts (PSCs) in saline-alkaline soils. Abscisic acid (ABA) is a potent seed priming agent known for modulating plant physiological and metabolic responses under salinity stress. However, the influence of ABA priming on seedling emergence in PSCs remains unclear.

Mitochondrial antiviral-signaling protein (MAVS) is a key adapter protein required for inducing type I interferons (IFN-Is) and other antiviral effector molecules. The formation of MAVS aggregates on mitochondria is essential for its activation; however, the regulatory mitochondrial factor that mediates the aggregation process is unknown. Our recent work has identified the protein Aggregatin as a critical seeding factor for β-amyloid peptide aggregation.

Two-dimensional covalent organic frameworks (2D-COFs) exhibit high activity in the electrochemical nitrogen reduction reaction (NRR), while the structure-performance relationship toward which remains an unsolved problem, therefore hindering the development of efficient catalysts. In this work, a total of 145 candidate transition metal phthalocyanine (TMPc-DX) materials comprised of 29 transition metals and X-phthalocyanine (X = N, O, F, S, and Cl) are evaluated for their capabilities in the NRR by density functional theory calculations. Our computations showed that metal atoms in TMPc-DN/DF/DCl materials could efficiently activate N molecules by doping with electron-withdrawing groups.

Serpins (serine protease inhibitors) constitute a superfamily of proteins with functional diversity and unusual conformational flexibility. In insects, serpins act as multiple inhibitors, by forming inactive acyl-enzyme complexes, in regulating Spätzles activation, phenoloxidases (POs) activity, and other cytokines. In this study, we present the cloning and characterization of Octodonta nipae serpin2 (OnSPN2), a 415 residues protein homologous to Tenebrio molitor 42Dd-like.

Quantification of transcription activities in mammalian preimplantation embryos is challenging due to a huge amount of maternally stored transcripts and paucity of research materials. Here, we investigate genome-wide transcription activities of mouse and human preimplantation embryos by quantifying elongating RNA polymerase II. Two transcriptional waves are identified in early mouse embryos, with summits at the 2-cell and 8-cell stages.

Tactile sensation and recognition in the human brain are indispensable for interaction between the human body and the surrounding environment. It is quite significant for intelligent robots to simulate human perception and decision-making functions in a more human-like way to perform complex tasks. A combination of tactile piezoelectric sensors with neuromorphic transistors provides an alternative way to achieve perception and cognition functions for intelligent robots in human-machine interaction scenarios.

The study of structure-activity relationships is a top priority in the development of nontraditional luminescent materials. In this work, nonconjugated polyurethanes (PUs) with full-color emission (red, green, and blue) are easily obtained by control of the diol monomer structure and the polymerization conditions. Selected diol monomers introduced single, double, or triple bond repeating units into the main chain of the PUs, in order to understand how unsaturated bonds and H-bonds affect their luminescence from a molecular orbital viewpoint.

Controlling symmetrical or asymmetrical growth has allowed a series of novel nanomaterials with prominent physicochemical properties to be produced. However, precise and continuous size growth based on a preserved template has long been a challenging pursuit, yet little has been achieved in terms of manipulation at the atomic level. Here, a correlated silver cluster series has been established, enabling atomically precise manipulation of symmetrical and asymmetrical surface structure expansions of metal nanoclusters.

Anticancer peptides (ACPs) demonstrate significant potential in clinical cancer treatment due to their ability to selectively target and kill cancer cells. In recent years, numerous artificial intelligence (AI) algorithms have been developed. However, many predictive methods lack sufficient wet lab validation, thereby constraining the progress of models and impeding the discovery of novel ACPs.

Background: Triple-negative breast cancer (TNBC) is a particularly aggressive type of breast cancer, known for its lack of effective treatments and unfavorable prognosis. The G protein-coupled estrogen receptor (GPER), a novel estrogen receptor, is linked to increased malignancy in various cancers. However, its involvement in the metabolic regulation of cancer-associated fibroblasts (CAFs), a key component in the tumour microenvironment, remains largely unexplored.

Article Synopsis
  • Recognizing cryptic species is essential for our understanding of global biodiversity, particularly for a widely distributed intertidal snail in the Northwest Pacific.
  • Traditional methods of identifying these species using morphology and single genetic markers have shown conflicting results, prompting a comprehensive study using both quantitative morphology and whole-genome molecular data.
  • The research identified significant morphological differences and genetic divergence among the snail species, confirming that the population north of the Yangtze River Estuary represents a cryptic species, and highlighting the role of allopatric speciation within the complex.

Purpose Of Review: Dietary phytochemicals, bioactive compounds derived from plants, have gained increasing attention for their potential role in cancer prevention. Among these, NRF2 (nuclear factor erythroid 2-related factor 2) activating dietary phytochemicals such as curcumin, sulforaphane, ursolic acid, and cyanidin have demonstrated significant antioxidant and anti-inflammatory properties, making them promising agents in chemoprevention. This review examines the pharmacokinetic (PK) and pharmacodynamic (PD) profiles of these dietary phytochemicals, with a focus on their NRF2-mediated effects in cancer prevention.

In this paper, the free vibration of piezoelectric nanobeams considering static flexoelectric, dynamic flexoelectric, and surface effects is studied. Based on the theories of the Timoshenko beam and Euler-Bernoulli beam, a theoretical model of flexoelectric nanobeams is established and the governing equations and boundary conditions of this model are derived using the variational principle. Then, the analytical solution of the frequency equation is obtained by using the Navier method.

In the era of transcriptomics, the role of epigenetics in the study of cancers in females has gained increasing recognition. This article explores the impact of epigenetic modifications, such as DNA methylation, histone modification, and non-coding RNA, on cancers in females, including breast, cervical, and ovarian cancers (1). Our findings suggest that these epigenetic markers not only influence tumor onset, progression, and metastasis but also present novel targets for therapeutic intervention.
