    Abstract Due to the molecular and cellular heterogeneity of glioma, discovery of novel targeted sites and ligands for glioma imaging and therapy remains challenging. Neuropeptide Y (NPY) Y1 receptors (Y1Rs) are highly over expressed in various brain tumors including glioma, and can serve as potential targeting sites for glioma imaging and therapy. Here, we show by in vivo fluorescent imaging that a highly selective Y1R ligand, [Asn6, Pro34] NPY (AP-NPY), facilitated circumvention of the blood brain barrier (BBB) by nanomicelles specifically targeting glioma. Modification with AP-NPY stabilized doxorubicin-loaded nanomicelles in the normal physiological state and promoted drug release in the acidic tumor microenvironment. Furthermore, targeted delivery of AP-NPY nanomicelles improved the therapeutic efficacy of doxorubicin for glioma, producing a prolonged survival rate. These results suggest that Y1R is a novel targeted receptor, and its selective ligand AP-NPY improves BBB permeability and glioma targeting. Our study paves the way for developing a novel delivery system for diagnosis and treatment of glioma in which Y1Rs are over expressed.

    Abstract With the success of large-scale pre-trained models (PTMs), how efficiently adapting PTMs to downstream tasks has attracted tremendous attention, especially for PTMs with billions of parameters. Although some parameter-efficient tuning paradigms have been proposed to address this problem, they still require large resources to compute the gradients in the training phase. In this paper, we propose $\mathcal{Y}$-Tuning, an efficient yet effective paradigm to adapt frozen large-scale PTMs to specific downstream tasks. $\mathcal{Y}$-tuning learns dense representations for labels $\mathcal{Y}$ defined in a given task and aligns them to fixed feature representation. Without tuning the features of input text and model parameters, $\mathcal{Y}$-tuning is both parameter-efficient and training-efficient. For $\text{DeBERTa}_\text{XXL}$ with 1.6 billion parameters, $\mathcal{Y}$-tuning achieves performance more than $96\%$ of full fine-tuning on GLUE Benchmark with only $2\%$ tunable parameters and much fewer training costs.

    Abstract The effects of laser parameters on the microstructure and properties of plasma-sprayed yttrium oxide coating on the graphite matrix were investigated. Tensile strength, porosity, roughness, and scratch meter tests were carried out to evaluate the critical load and mechanical properties of the coating after spraying and laser micro-melting. When the porosity and surface roughness of the coating are minimum, the critical load of the coating is 7.85 N higher than that of the spraying surface. After laser micromelting, the crystal phase of Y

    Abstract Objective: Detection of azoospermia factor (AZF) microdeletions on the Y chromosome is one of the auxiliary strategies recognized at home and abroad for the examination of male infertility. Traditional PCR gel electrophoresis fails to meet the clinical needs due to its shortcomings. The purpose of this study was to explore the feasibility of multiplex fluorescence PCR in the detection of AZF microdeletions.
    Methods: We collected samples of Y chromosomal AZF microdeletions from 238 patients with azoospermia or oligozoospermia and 62 normal males, identified the 14 short tandem repeat (STR) loci in the AZF region of the Y chromosome by multiplex PCR gel electrophoresis and multiplex fluorescence PCR, and analyzed the consistency in the results of the two methods by Kappa test.
    Results: There was a perfect consistency between multiplex PCR gel electrophoresis and multiplex fluorescence PCR in the detection rate of the STR loci in the 300 samples. Kappa test showed both P and Kappa values to be 1 for the 6 loci in the AZFa, AZFb and AZFc regions of the Y chromosome, with no statistically significant difference between the two methods.
    Conclusions: Multiplex fluorescence PCR can save a lot of time, reduce workload and improve laboratory efficiency and therefore is preferable to multiplex PCR gel electrophoresis in detecting Y chromosome microdeletions.

    Abstract Backgrounds: Y-chromosomal haplotypes based on Y-short tandem repeats (STRs) and Y-single nucleotide polymorphisms/insertion and deletion polymorphisms (SNPs/InDels) are used to characterize paternal lineages of unknown male trace donors. However, Y-chromosomal genetic markers are not currently sufficient for precise individual identification. Microhaplotype (MH), generally < 200 bp on autosomes and consisting of two or more SNPs, was recently introduced in forensic genetics with the development of massive parallel sequencing technology and may facilitate identification and DNA mixture deconvolution. Therefore, combining the two kinds of genetic markers may be beneficial in many forensic scenarios, especially crime scenes with male suspects, such as sexual assault cases.
    Methods: In the present study, we developed a novel MPS-based panel, Microhaplotype and Y-SNP/STR (MY), by multiplex PCR and 150-bp paired-end sequencing, including 114 Y-SNPs (twelve dominant Y-DNA haplogroups), 45 Y-STRs (N-1 stutter < 0.09; estimated mutation rate < 5 × 10

    Conclusion: The GPR can be used to deconvolute two-person DNA mixtures (application range: 1:10-1:2) for individual identification.

    Abstract Genome sequencing and genetic mapping of molecular markers have demonstrated nearly complete Y-linkage across much of the guppy (Poecilia reticulata) XY chromosome pair. Predominant Y-linkage of factors controlling visible male-specific coloration traits also suggested that these polymorphisms are sexually antagonistic (SA). However, occasional exchanges with the X are detected, and recombination patterns also appear to differ between natural guppy populations, suggesting ongoing evolution of recombination suppression under selection created by partially sex-linked SA polymorphisms. We used molecular markers to directly estimate genetic maps in sires from 4 guppy populations. The maps are very similar, suggesting that their crossover patterns have not recently changed. Our maps are consistent with population genomic results showing that variants within the terminal 5 Mb of the 26.5 Mb sex chromosome, chromosome 12, are most clearly associated with the maleness factor, albeit incompletely. We also confirmed occasional crossovers proximal to the male-determining region, defining a second, rarely recombining, pseudo-autosomal region, PAR2. This fish species may therefore have no completely male-specific region (MSY) more extensive than the male-determining factor. The positions of the few crossover events suggest a location for the male-determining factor within a physically small repetitive region. A sex-reversed XX male had few crossovers in PAR2, suggesting that this region's low crossover rate depends on the phenotypic, not the genetic, sex. Thus, rare individuals whose phenotypic and genetic sexes differ, and/or occasional PAR2 crossovers in males can explain the failure to detect fully Y-linked variants.

    Abstract Postmenopausal osteoporosis (PMO) is often accompanied by neuroendocrine changes in the hypothalamus, which closely associates with the microbial diversity, community composition, and intestinal metabolites of gut microbiota (GM). With the emerging role of GM in bone metabolism, a potential neuroendocrine signal neuropeptide Y (NPY) mediated brain-gut-bone axis has come to light. Herein, it is reported that exogenous overexpression of NPY reduced bone formation, damaged bone microstructure, and up-regulated the expressions of pyroptosis-related proteins in subchondral cancellous bone in ovariectomized (OVX) rats, but Y1 receptor antagonist (Y1Ra) reversed these changes. In addition, it is found that exogenous overexpression of NPY aggravated colonic inflammation, impaired intestinal barrier integrity, enhanced intestinal permeability, and increased serum lipopolysaccharide (LPS) in OVX rats, and Y1Ra also reversed these changes. Most importantly, NPY and Y1Ra modulated the microbial diversity and changed the community composition of GM in OVX rats, and thereby affecting the metabolites of GM (e.g., LPS) entering the blood circulation. Moreover, fecal microbiota transplantation further testified the effect of NPY-mediated GM changes on bone. In vitro, LPS induced pyroptosis, reduced viability, and inhibited differentiation of osteoblasts. The study demonstrated the existence of NPY-mediated brain-gut-bone axis and it might be a novel emerging target to treat PMO.
