The univariate and multivariate analyses were conducted to analyze the risk factors of the occurrence of anxiety and depression.

Bdyof is a Y-chromosome-specific gene required for male development in Bactrocera dorsalis.

Background: In many organisms, the Y chromosome contains important genes associated with sex determination and male reproductive development. However, there have been few studies of Y-chromosome-specific genes in non-model species due to the incomplete information of Y chromosome genome and difficulty in sequencing. Here, we screened 90 candidate Y-specific sequences in a constructed transcriptome assembly library by using the chromosome quotient method, among which 11 were unreported sequences associated with male reproductive development, including Bactrocera dorsalis Y-specific Oligozoospermia factor (Bdyof) with the highest expression in the testis.

Early detection of anthracycline-induced cardiotoxicity.

Although anthracyclines are important anticancer agents, their use is limited due to various adverse effects, particularly cardiac toxicity. Mechanisms underlying anthracycline-induced cardiotoxicity (AIC) are complex. Given the irreplaceable role of anthracyclines in treatment of malignancies and other serious diseases, early monitoring of AIC is paramount.

In this study, we identified 9 Y chromosome genes in Zeugodacus tau (Diptera: Tephritidae), including gene 16222.

Interaction of antiphospholipid antibodies with endothelial cells in antiphospholipid syndrome.

Antiphospholipid syndrome (APS) is an autoimmune disease with arteriovenous thrombosis and recurrent miscarriages as the main clinical manifestations. Due to the complexity of its mechanisms and the diversity of its manifestations, its diagnosis and treatment remain challenging issues. Antiphospholipid antibodies (aPL) not only serve as crucial "biomarkers" in diagnosing APS but also act as the "culprits" of the disease.

Bulk T-cell receptor sequencing confirms clonality in obstetric antiphospholipid syndrome and may as a potential biomarker.

The heterogeneity of the T cell receptor (TCR) repertoire critically influences the autoimmune response in obstetric antiphospholipid syndrome (OAPS) and is intimately associated with the prophylaxis of autoimmune disorders. Investigating the TCR diversity patterns in patients with OAPS is thus of paramount clinical importance. This investigation procured peripheral blood specimens from 31 individuals with OAPS, 21 patients diagnosed with systemic lupus erythematosus (SLE), and 22 healthy controls (HC), proceeding with TCR repertoire sequencing.

YAP inhibition overcomes adaptive resistance in HER2-positive gastric cancer treated with trastuzumab via the AKT/mTOR and ERK/mTOR axis.

Background: Human epidermal growth factor receptor 2 (HER2)-positive gastric cancer (GC) is a heterogeneous GC subtype characterized by the overexpression of HER2. To date, few specific targeted therapies have demonstrated durable efficacy in HER2-positive GC patients, with resistance to trastuzumab typically emerging within 1 year. However, the mechanisms of resistance to trastuzumab remain incompletely understood, presenting a significant challenge to clinical practice.
