Ultrasensitive and high selectivity detection of fibrin using Y-shaped DNA-homing peptide doped probe on localized surface plasmon resonance platform.

Background: Localized surface plasmon resonance (LSPR) sensor has drawn continuous attention to application of the detection of antibody, protein, virus, and bacteria. However, natural recognition molecules, such as antibody, which possess some properties, including low thermal stability, complicated operation and high price, uncontrollability of length and size and a tendency to accumulate easily on the surface of chip to reduce the sensitive of method. Furthermore, common blocking agents are not suitable for development of novel biosensors.

A Y-Shaped Peptide-Based Antifouling Electrochemical Aptasensor for Sensitive Aflatoxin B1 Detection in Food.

Conquering surface fouling of sensors caused by nonspecific adsorption and accumulation of foulants in a food matrix is of significance in accurate food safety analysis.

Spatial omics-based machine learning algorithms for the early detection of hepatocellular carcinoma.

Background: Worldwide, hepatocellular carcinoma (HCC) is the second most lethal cancer, although early-stage HCC is amenable to curative treatment and can facilitate long-term survival. Early detection has proved difficult, as proteomics, transcriptomics, and genomics have been unable to discover suitable biomarkers.

Methods: To find new biomarkers of HCC, we utilized a spatial omics N-glycan imaging method to identify altered glycosylation in cancer tissue (n = 53) and in paired serum of individuals with HCC (n = 23).

Evolution of Sex-linked Genes and the Role of Pericentromeric Regions in Sex Chromosomes: Insights from Diploid Willows.

The evolution of sex chromosomes can involve recombination suppression sometimes involving structural changes, such as inversions, allowing subsequent rearrangements, including inversions and gene transpositions. In the two major genus Salix clades, Salix and Vetrix, almost all species are dioecious, and sex-linked regions have evolved on chromosome 7 and 15, with either male or female heterogamety. We used chromosome conformation capture (Hi-C) and PacBio HiFi (high-fidelity) reads to assemble chromosome-level, gap-free X and Y chromosomes from both clades, S.

ChromaFold predicts the 3D contact map from single-cell chromatin accessibility.

Identifying cell-type-specific 3D chromatin interactions between regulatory elements can help decipher gene regulation and interpret disease-associated non-coding variants. However, achieving this resolution with current 3D genomics technologies is often infeasible given limited input cell numbers. We therefore present ChromaFold, a deep learning model that predicts 3D contact maps, including regulatory interactions, from single-cell ATAC sequencing (scATAC-seq) data alone.

Acidic Extracellular pH-Activated Allosteric DNA Nanodevice for Fluorescence Imaging of APE1 Activity in Tumor Cells.

Allostery is a phenomenon where the binding of a ligand at one allosteric site influences the affinity for another ligand at an active site. Different from orthosteric regulation, it allows for more precise control of biomolecular activity and enhances the stability of the molecules. Inspired by allosteric regulation of natural molecules, we present a Y-shaped allosteric DNA nanodevice, termed YssAP, that was pH-responsive and functionalized with the AS1411 aptamer for accurate fluorescence imaging of human apurinic/apyrimidinic endonuclease (APE1) activity in tumor cells.

Effect of Y-shaped Nasal Columella Made of Autologous Cartilage in Secondary Nasal Deformity after Cleft Lip Surgery.

Aim: Due to the diversity and complexity of tissues involved in secondary nasal deformities following unilateral cleft lip, secondary nasal deformity correction surgeries are challenging and often yield unsatisfactory results, posing a difficult problem for plastic surgeons. Autologous cartilage, with its low sculpting difficulty, minimal absorption, and stable tissue compatibility, is considered the optimal material for reconstructing the columella, nasal tip, and alar. This study analyzed the clinical outcomes of using autologous cartilage to create a Y-shaped columella to correct secondary nasal deformities after cleft lip surgery.

Precursor central memory versus effector cell fate and naïve CD4+ T cell heterogeneity.

Upon antigenic stimulation, naïve CD4+ T cells can give rise to phenotypically distinct effector T helper cells and long-lived memory T cells. We computationally reconstructed the in vivo trajectory of CD4+ T cell differentiation during a type I inflammatory immune response and identified two distinct differentiation paths for effector and precursor central memory T cells arising directly from naïve CD4+ T cells. Unexpectedly, our studies revealed heterogeneity among naïve CD4+ T cells, which are typically considered homogeneous save for their diverse T cell receptor usage.
