AI Article Synopsis
Article Abstract
To achieve specificity and sensitivity using immunohistochemistry it is necessary to combine the application of validated primary antibodies with optimised pre-treatment, detection and visualisation steps. The influence of these surrounding procedures is reviewed. A practical evaluation of tyramide signal amplification and rolling circle amplification detection methods is provided in which formalin fixed paraffin embedded sections of adenocarcinomas of breast, colon and lung together with squamous metaplasia of lung were immunostained with CD20 and CK19 primary antibodies. The results indicate that the detection systems are of comparable sensitivity and specificity.

Toxoplasma gondii, an obligate intracellular protozoan, infects almost all warm-blooded animals and humans, with felines serving as its sole definitive hosts. Cats release T. gondii oocysts into the environment through feces, contributing to environmental contamination that can lead to toxoplasmosis in humans upon exposure through ingestion of contaminated food, water, or soil.

Determination of the Time-frequency Features for Impulse Components in EEG Signals.

Institute of Mathematics, University of Kassel, Heinrich-Plett-Str. 40, Kassel, 34132, Germany.
Accurately identifying the timing and frequency characteristics of impulse components in EEG signals is essential but limited by the Heisenberg uncertainty principle. Inspired by the visual system's ability to identify objects and their locations, we propose a new method that integrates a visual system model with wavelet analysis to calculate both time and frequency features of local impulses in EEG signals. We develop a mathematical model based on invariant pattern recognition by the visual system, combined with wavelet analysis using Krawtchouk functions as the mother wavelet.

The detection of disease-related protein biomarkers plays a crucial role in the early diagnosis, treatment, and monitoring of diseases. The concentrations of protein biomarkers can vary significantly in different diseases or stages of the same disease. However, most of the existing analytical methods cannot simultaneously meet the requirements of high sensitivity and a wide dynamic range.

Intraoperative hemodynamic monitoring is crucial for managing patients with end-stage liver disease (ESLD) undergoing orthotopic liver transplantation (OLT) due to their complex cardiovascular and pulmonary abnormalities. Traditionally, pulmonary artery catheterization (PAC) has been the standard for hemodynamic monitoring during OLT. However, the use of transesophageal echocardiography (TEE) has increased due to its real-time visualization of cardiac and vascular structures, which aids in managing hemodynamic instability during the three surgical phases of OLT: pre-anhepatic, anhepatic, and neo-hepatic.
