Diagnostic accuracy of urinary prostate protein glycosylation profiling in prostatitis diagnosis [PDF]

, 2015
Introduction: Although prostatitis is a common male urinary tract infection, clinical diagnosis of prostatitis is difficult. The developmental mechanism of prostatitis is not yet unraveled which led to the elaboration of various biomarkers. As changes in

INB3P: A Multi‐Modal and Interpretable Co‐Attention Framework Integrating Property‐Aware Explanations and Memory‐Bank Contrastive Fusion for Blood–Brain Barrier Penetrating Peptide Discovery

Advanced Science, EarlyView.
INB3P is a multimodal framework for blood–brain barrier‐penetrating peptide prediction under extreme data scarcity and class imbalance. By combining physicochemical‐guided augmentation, sequence–structure co‐attention, and imbalance‐aware optimization, it improves predictive performance and interpretability.

EFFECTS OF CHRONIC RENAL FAILURE AND HEMODIALYSIS ON SERUM PSA, FREE PSA, FREE/TOTAL PSA RATIOS

Urology Research and Practice, 2019
Little is known of the impact of hemodialysis on serum total (tPSA) and free PSA (fPSA) levels. We prospectively studied the impact of hemodialysis with low-flux membranes on serum tPSA, fPSA and free/total PSA (f/tPSA) ratios.

Artificial neural network (ANN) velocity better identifies benign prostatic hyperplasia but not prostate cancer compared with PSA velocity [PDF]

, 2008
Background To validate an artificial neural network (ANN) based on the combination of PSA velocity (PSAV) with a %free PSA-based ANN to enhance the discrimination between prostate cancer (PCa) and benign prostate hyperplasia (BPH).

Decoding Tattoo and Permanent Makeup Pigments: Linking Physicochemical Properties to Absorption, Distribution, Metabolism, and Elimination Profiles Using Quantitative Structure–Activity Relationship (QSAR)‐Based New Approach Methodologies (NAMs)

Advanced Intelligent Discovery, EarlyView.
This study applies QSAR‐based new approach methodologies to 90 synthetic tattoo and permanent makeup pigments, revealing systemic links between their physicochemical properties and absorption, distribution, metabolism, and elimination profiles. The correlation‐driven analysis using SwissADME, ChemBCPP, and principal component analysis uncovers insights

A Machine Learning Perspective on the Brønsted–Evans–Polanyi Relation in Water‐Gas Shift Catalysis on MXenes

Advanced Intelligent Discovery, EarlyView.
Machine learning predicts activation energies for key steps in the water‐gas shift reaction on 92 MXenes. Random Forest is identified as the most accurate model. Reaction energy and reactant LogP emerge as key descriptors. The approach provides a predictive framework for catalyst design, grounded in density functional theory data and validated through ...

PSA – biomarker, mis on muutnud eesnäärmehaiguste kliinilist käsitlust [PDF]

, 2009
Prostataspetsiifi line antigeen on enim kasutatav eesnäärmehaiguste marker kliinilises meditsiinis, mille tähtsus prostata biomarkerina avastati 1979. aastal. Oluline on teada, et PSA on eesnäärme-, mitte kasvajaspetsiifi line marker.

A two‐stage model for precise identification and Gleason grading of clinically significant prostate cancer: a hybrid approach

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 93-105, March 2025.
This study developed a two‐stage model using radiomics‐based multiparametric MRI and clinical indicators to help identify and grade clinically significant prostate cancer. The model showed promising levels of diagnostic accuracy and predictive performance.

Cardioprotective effect of spirulina on cafeteria diet‐induced cardiac injury in silico and in vivo study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Obesity is a major risk factor for cardiovascular disease, primarily due to its effects on lipid metabolism, oxidative stress, and inflammation. The aim of this study was to evaluate the effects of spirulina (SP) on cafeteria diet (CD)‐induced myocardial oxidative stress and inflammation using biochemical, histological, and in ...
