Machine Learning-Based Pathomics Model to Predict the Prognosis in Clear Cell Renal Cell Carcinoma.

Clear cell renal cell carcinoma (ccRCC) is a highly lethal urinary malignancy with poor overall survival (OS) rates. Integrating computer vision and machine learning in pathomics analysis offers potential for enhancing classification, prognosis, and treatment strategies for ccRCC. This study aims to create a pathomics model to predict OS in ccRCC patients.

Comparative evaluation of SanAgileSA01 ultrasonic scalpel and Johnson & Johnson GEN11, and HAR36 for efficacy and safety.

Background: The advent of ultrasonic scalpels has remarkably advanced minimally invasive surgery; however, the Chinese market's reliance on imports highlights the urgent need for a cost-effective, efficient, and domestically produced surgical scalpel. This study aimed to compare SanAgileSA01 with the Johnson & Johnson GEN11, and HAR36 surgical devices.

Research Design And Methods: In total, 152 participants requiring urological or general laparoscopic surgery were randomly and equally divided between the two hospitals and randomized to the test and control groups.

Forkhead box F1 functions as a novel prognostic biomarker and induces caspase‑dependent apoptosis in bladder cancer.

The downregulated expression of forkhead box F1 (FOXF1) has been found in many malignant tumors but no research was done in bladder cancer (BC). The present study aimed to investigate the prognostic value and antitumor effects of FOXF1 in patients with BC. Herein, a retrospectively recruited BC cohort and public datasets were utilized to identify the predictive ability of FOXF1 and determine its association with the clinical characteristics of BC patients.

TRIM38 triggers the uniquitination and degradation of glucose transporter type 1 (GLUT1) to restrict tumor progression in bladder cancer.

Background: Loss-of-function mutations or abnormal expressions of E ubiquitin ligases contributes to tumorigenesis. TRIM38 was reported to regulate immunity, inflammatory responses or apoptosis, but its roles in tumor progression remain inconclusive. This study aimed to investigate the functional roles of TRIM38 in bladder cancer to identify effective targets.

Overexpression of DDR1 Promotes Migration, Invasion, Though EMT-Related Molecule Expression and COL4A1/DDR1/MMP-2 Signaling Axis.

Predictors of hypertension urgency in primary aldosteronism patients during the first 24 hours after surgery.

Study about blood pressure variation in the first 24 hours post-operation is limited in patients with adrenal aldosterone-producing adenoma. We aim to evaluate the potential predictors for postoperative hypertension urgency during the first 24 hours after laparoscopic adrenalectomy in patients with aldosterone-producing adenoma. Clinical data of 177 patients with aldosterone-producing adenoma were retrospectively collected from January 2009 to December 2015 and the potential factors that may influence postoperative blood pressure during the first 24 hours after surgery were analyzed.

Discoidin domain receptor 1 activity drives an aggressive phenotype in bladder cancer.

Discoidin domain receptor 1 (DDR1) is a receptor tyrosine kinase which utilizes collagen as a ligand to regulate the interaction between cancer cells and tumor stroma. However, the clinical relevance of DDR1 expression in bladder cancer as well as its molecular regulation have not been previously investigated. Here, we assessed the role of DDR1 in bladder cancer.

Magnetic coherent tunnel junctions with periodic grating barrier.

A new spintronic theory has been developed for the magnetic tunnel junction (MTJ) with single-crystal barrier. The barrier will be treated as a diffraction grating with intralayer periodicity, the diffracted waves of tunneling electrons thus contain strong coherence, both in charge and especially in spin. The theory can answer the two basic problems present in MgO-based MTJs: (1) Why does the tunneling magnetoresistance (TMR) oscillate with the barrier thickness? (2) Why is the TMR still far away from infinity when the two electrodes are both half-metallic? Other principal features of TMR can also be explained and reproduced by the present work.

Expression of kallikrein-related peptidase 7 is decreased in prostate cancer.

Recent evidence suggests that the human kallikrein 7 (KLK7) is differentially regulated in a variety of tumors. The aim of this study was to determine the expression of kallikrein-related peptidase 7 and KLK7 in our large collection of prostate samples. Between August 2000 and December 2012, 116 patients with histologically confirmed prostate cancer (PCa) and 92 with benign prostate hyperplasia (BPH) were recruited into the study.

The role of unilateral adrenalectomy in corticotropin-independent bilateral adrenocortical hyperplasias.

Background: The objective of the present study was twofold: to demonstrate our experience with unilateral adrenalectomy in the treatment of adrenocorticotropic hormone (ACTH)-independent Cushing syndrome (CS) caused by bilateral adrenocortical hyperplasias, and to evaluate the long-term results as evidenced by the main laboratory and clinical findings.

[Efficacy and safety of tadalafil for erectile dysfunction: an updated review].

As a long-acting phosphodiesterase type 5 (PDE5) inhibitor, tadalafil is administered orally as the first line therapy for erectile dysfunction (ED). Its efficacy and safety have been confirmed by many clinical studies in the treatment of ED in general patients, elderly patients and those with diabetes mellitus or spinal cord injury or after prostate cancer surgery. With its prolonged action of 36 hours, tadalafil can not only increase the self-esteem of ED men but also improve the quality of life of both the patients and their partners.
