Development and validation of a radiomics-based nomogram for predicting pathological grade of upper urinary tract urothelial carcinoma.

Background: Upper urinary tract urothelial carcinoma (UTUC) is a rare and highly aggressive malignancy characterized by poor prognosis, making the accurate identification of high-grade (HG) UTUC essential for subsequent treatment strategies. This study aims to develop and validate a nomogram model using computed tomography urography (CTU) images to predict HG UTUC.

Methods: A retrospective cohort study was conducted to include patients with UTUC who underwent radical nephroureterectomy and received a CTU examination prior to surgery.

Antibody‑drug conjugates in prostate cancer: Emerging strategies to enhance therapeutic index and current clinical landscape (Review).

The global incidence of prostate cancer (PCa) is rising. Localized PCa can be managed through surgical intervention or radiotherapy, but certain patients may experience recurrence or develop metastatic disease following localized treatment. Despite aggressive therapeutic approaches, the majority of metastatic patients with PCa will eventually progress to metastatic castration‑resistant PCa, with limited treatment alternatives and a dismal prognosis.

Circ_0001047 inhibits prostate cancer progression and enhances abiraterone sensitivity via miR-122-5p/FKBP5/PHLPP1/AKT axis in vitro.

Prostate cancer (PCa), with high heterogeneity and poor prognosis, is one of the most common malignant tumors in men. Circular RNAs (circRNAs) have been identified in tumor progression and resistance to medication in numerous studies. However, the role of circ_0001047 in PCa is unclear.

STAT1 as a potential therapeutic target to treat bladder cancer.

Background: Previous studies have reported that STAT1 (Signal Transducer and Activator of Transcription 1) is associated with multiple tumor progression. This study aimed to investigate the role and related mechanisms of STAT1 in bladder cancer.

Methods: STAT1 expression in bladder cancer tissues and human bladder cancer cell lines was assessed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR).

Bayesian-based analysis of the causality between 731 immune cells and erectile dysfunction: a two-sample, bidirectional, and multivariable Mendelian randomization study.

Background: The causal relationship between certain immune cells and erectile dysfunction (ED) is still uncertain.

Aim: The study sought to investigate the causal effect of 731 types of immune cells on ED through Mendelian randomization (MR) using genome-wide association studies (GWAS).

Methods: Genetic instruments for 731 immune cells were identified through GWAS, and ED data were obtained from the FinnGen database.

Discovery andsynthesis of novel benzoylhydrazone neuraminidase inhibitors.

Neuraminidase (NA) serves as a promising target for the exploration and development of anti-influenza drugs. In this work, lead compound 5 was discovered through pharmacophore-based virtual screening and molecular dynamics simulation, and 14 new compounds were obtained by modifying the lead compound 5 based on pharmacophore features. The biological activity test shows that 5n (IC = 0.

Effect of High-quality Nursing Care Combined with Psychological Intervention on Stress Response in Surgery and Postoperative Negative Emotions of Patients Undergoing General Anesthesia.

Objective: This study investigated the effect of high-quality nursing care combined with psychological intervention on the stress response and postoperative negative emotions of patients undergoing general anesthesia for surgery.

Methods: From January 2019 to January 2020, the researchers chose 90 patients who received general anesthesia at Liaocheng People's Hospital for this study. The patients were divided into control and study groups, each with 45 patients.

Multi-omics landscape analysis reveals the pan-cancer association of arginine biosynthesis genes with tumor immune evasion and therapy resistance.

Background: The metabolism of arginine, a conditionally essential amino acid, plays a crucial role in cancer progression and prognosis. However, a more detailed understanding of the influence of arginine biosynthesis genes in cancer is currently unavailable.

Methods: We performed an integrative multi-omics analysis using The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases to determine the characteristics of these genes across multiple cancer types.

Application of remimazolam-0.6% sevoflurane anesthesia for flash visual evoked potential monitoring during pituitary adenoma resection: a non-inferiority randomized controlled trial.

Background: Flash visual evoked potential (FVEP) is a critical method for monitoring intraoperative visual function during neurosurgery. A new benzodiazepine drug called remimazolam has recently been used for general anesthesia. However, the impact of remimazolam on FVEP remains unclear.

The role of the genetic influence of DRD4 in Chinese adults in the context of the choice of tourist attractions.

The aim of this work was to analyse the effect of tandem repetitions in exon III of the DRD4 gene on the features of human decision-making in a model of choosing tourist attractions by adult residents of China. The study included 380 subjects: 162 (42.6%) men and 218 (57.

is a potential biomarker for bladder cancer: a Mendelian randomization study.

Patients with bladder cancer (BLCA) have a poor prognosis and little progress has been made in treatment. Therefore, the purpose of this work was to employ Mendelian randomization (MR) and transcriptome analysis to identify a novel biomarker that could be used to reliably diagnose BLCA. TCGA-BLCA and GSE121711 datasets were obtained from public databases.

Robot-assisted radical cystectomy with intracorporeal urinary diversion: an updated systematic review and meta-analysis of its differential effect on effectiveness and safety.

Background: Robot-assisted laparoscopic cystectomy with intracorporeal urinary diversion (iRARC) is increasingly being used in recent years. Whether iRARC offers advantages over open radical cystectomy (ORC) remains controversial. This study aimed to compare the difference of perioperative outcomes, oncological outcomes and complications between iRARC and ORC.

Development of a stemness-related prognostic index to provide therapeutic strategies for bladder cancer.

Bladder cancer (BC) is a heterogeneous disease with varying clinical outcomes. Recent evidence suggests that cancer progression involves the acquisition of stem-like signatures, and assessing stemness indices help uncover patterns of intra-tumor molecular heterogeneity. We used the one-class logistic regression algorithm to compute the mRNAsi for each sample in BLCA cohort.

An integrated approach for improving clinical management of non-obstructive azoospermia.

Background: Non-obstructive azoospermia is the most severe form of male infertility. A testicular biopsy is required for the diagnosis of non-obstructive azoospermia, and the causal factors for non-obstructive azoospermia remain unknown.

Objectives: To reduce the risk of multiple biopsies and identify factors that contribute to non-obstructive azoospermia, we proposed an integrated approach for the preoperative diagnosis and clinical management of non-obstructive azoospermia by applying the chromosome-spreading technique and whole-exome sequencing.

LASS2 enhances chemosensitivity to cisplatin by inhibiting PP2A-mediated β-catenin dephosphorylation in a subset of stem-like bladder cancer cells.

Background: The benefits of first-line, cisplatin-based chemotherapy for muscle-invasive bladder cancer are limited due to intrinsic or acquired resistance to cisplatin. Increasing evidence has revealed the implication of cancer stem cells in the development of chemoresistance. However, the underlying molecular mechanisms remain to be elucidated.

The male pachynema-specific protein MAPS drives phase separation in vitro and regulates sex body formation and chromatin behaviors in vivo.

Dynamic chromosome remodeling and nuclear compartmentalization take place during mammalian meiotic prophase I. We report here that the crucial roles of male pachynema-specific protein (MAPS) in pachynema progression might be mediated by its liquid-liquid phase separation in vitro and in cellulo. MAPS forms distinguishable liquid phases, and deletion or mutations of its N-terminal amino acids (aa) 2-9 disrupt its secondary structure and charge properties, impeding phase separation.
