Single-cell and spatial transcriptomics reveal SPP1-CD44 signaling drives primary resistance to immune checkpoint inhibitors in RCC.

Background: Immune checkpoint inhibitors (ICIs) are a cornerstone therapy for advanced renal cell carcinoma (RCC). However, significant rates of primary resistance hinder their efficacy, and the underlying mechanisms remain poorly understood. This study aims to unravel the tumor-immune interactions and signaling pathways driving primary resistance to ICIs in RCC.

Relationship between circulating miRNA-222-3p and miRNA-136-5p and the efficacy of docetaxel chemotherapy in metastatic castration-resistant prostate cancer patients.

Background: Metastatic castration-resistant prostate cancer is the most dangerous stage of prostate cancer, with a high mortality rate. Docetaxel chemotherapy is one of the most effective treatment methods currently, but some patients do not respond to chemotherapy. To avoid unnecessary toxicity in non-responders, this study explores the potential of circulating microRNAs as early biomarkers of docetaxel response in patients with metastatic castration-resistant prostate cancer.

Formation mechanism and regulation analysis of trumpet leaf in L.

Introduction: The research on plant leaf morphology is of great significance for understanding the development and evolution of plant organ morphology. As a relict plant, the leaf morphology typically exhibits bifoliate and peltate forms. However, throughout its long evolutionary history, Ginkgo leaves have undergone diverse changes.

The greener the living environment, the better the health? Examining the effects of multiple green exposure metrics on physical activity and health among young students.

The sedentary and less active lifestyle of modern college students has a significant impact on the physical and mental well-being of the college community. Campus Green Spaces (GSs) are crucial in promoting physical activity and improving students' health. However, previous research has focused on evaluating campuses as a whole, without considering the diverse spatial scenarios within the campus environment.

Partial versus radical nephrectomy for the treatment of pT3aN0M0 renal cell carcinoma: A propensity score analysis.

Background: The survival benefit of partial nephrectomy (PN) in pT3a RCC patients is controversial. Here we aimed to explore the potential benefit of PN for pT3aN0M0 renal cell carcinoma (RCC).

Material And Methods: Data of patients with pT3aN0M0 RCC who were diagnosed between 2010 and 2012 in the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) database were retrospectively collected.

Temporal-spatial variation and the affecting factors of protected areas in Guizhou, China.

The establishment of protected areas is the bottom line of ecological security for promoting the construction of ecological civilization and supporting economic and social development, which is an important strategy to realize sustainable development and maintain ecological security. In order to reveal the large spatial process of protected areas and its influencing factors, we used the methods of nearest neighbor index, kernel density, and standard deviational ellipse to analyze the temporal-spatial variation characteristics of the protected areas in Guizhou Province from 2002 to 2017, as well as the influencing factors combined with geo-detectors. The results showed that, during the study period, the number, area, and types of protected areas in Guizhou Province showed a diversified and rapid development, forming a protected area system with nature reserves, forest parks and scenic spots as the main body and wetland parks, geoparks and natural heritage sites as the supplement.

A combination of the modified Stoppa approach and the iliac fossa approach in treating compound acetabular fractures by using an anterior ilioischial plate.

Most compound acetabular fractures involving both the anterior and posterior columns are caused by high-energy injuries. Patients with compound acetabular fractures are often in critical or poor condition and cannot tolerate major surgery. This study aims to investigate the effectiveness of an ilioischial plate in treating compound acetabular fractures.

[Correlation of 41 loci of single nucleotide polymorphisms with testicular germ cell tumor].

Objective: To identify genetic susceptibility genes and the loci of their single nucleotide polymorphisms (SNPs) in patients with testicular germ cell tumor (TGCT) and provide some new ideas for the prediction, diagnosis and treatment of TGCT.

Methods: We identified 41 SNP loci of TGCT-related genetic susceptibility genes from the literature published abroad. Using the iMLDRTM genotyping technique, we examined the SNP loci of the genetic susceptibility genes in the blood samples from 76 TGCT patients (aged 16－68 years) and 148 healthy men (aged 22－61 years) in China and analyzed their correlation with TGCT.

Ffuzz: Towards full system high coverage fuzz testing on binary executables.

Bugs and vulnerabilities in binary executables threaten cyber security. Current discovery methods, like fuzz testing, symbolic execution and manual analysis, both have advantages and disadvantages when exercising the deeper code area in binary executables to find more bugs. In this paper, we designed and implemented a hybrid automatic bug finding tool-Ffuzz-on top of fuzz testing and selective symbolic execution.

Clinical comparison of patients with benign urachal masses versus urachal carcinomas.

The clinical features of 17 patients with benign urachal masses and 30 patients with urachal carcinoma treated at Sun Yat-sen University Cancer Center were analyzed retrospectively. Univariate analysis indicated that seven parameters differed significantly between the two groups. Binary logistic regression analyses showed that the rate of gross hematuria was significantly higher (P = 0.

Bilateral pelvic lymph node dissection for Chinese patients with penile cancer: a multicenter collaboration study.

Background: Current guidelines recommend pelvic lymphadenectomy (PLND) for patients with pelvic lymph node metastasis and special state. However, these data and recommendations do not distinguish the role of PLND in different patient groups and confirm the final benefits. The aim of this study was to confirm the efficacy of pelvic lymphadenectomy (PLND) for the different groups of patients.

Evaluation of Vitronectin Expression in Prostate Cancer and the Clinical Significance of the Association of Vitronectin Expression with Prostate Specific Antigen in Detecting Prostate Cancer.

Purpose: To detect the expression of vitronectin (VTN) in the tissues and blood serum of prostate cancer (PCa) patients, and evaluate its clinical significance and to evaluate the significance of the combined assay of VTN and prostate specific antigens (PSA) in PCa diagnosis.

Materials And Methods: To detect the expression of VTN as a potential marker for PCa diagnosis and prognosis, immunohistochemistry was performed on the tissues of 32 patients with metastatic PCa (PCaM), 34 patients with PCa without metastasis (PCa), and 41 patients with benign prostatic hyperplasia (BPH). The sera were then subjected to Western blot analysis.

Effect and clinical significance of fast-track surgery combined with laparoscopic radical gastrectomy on the plasma level of vascular endothelial growth factor in gastric antrum cancer.

This study discusses the effect and clinical significance of fast-track surgery (FTS) combined with laparoscopic radical surgery on the plasma level of vascular endothelial growth factor (VEGF) in locally advanced gastric antrum cancer. Plasma VEGF levels were detected in 63 cases of locally advanced gastric antrum cancer by using double-antibody sandwich Avidinbiotincomplex-ELISA before and after operation. The pure laparoscopic surgery group (group A) comprised 30 cases, and the combined FTS group (group B) consisted of 33 cases.
