Published: December 2003

We have developed a quantitative filtration apparatus to evaluate erythrocyte deformability, using a precision metal filter which we developed. The test material is sucked into the filter through the action of decreasing negative pressure. The device automatically gives a liquid level (height)-time relation and a pressure-flow rate relation, similar to gravity-based filtration. Unlike the gravity-based system, the experimental performance of this system is very good and reproducible.

Aim: To study the associations between risk factors, clinical characteristics, severity of brachiocephalic artery (BCA) atherosclerosis and severity of coronary artery (CA) disease in patients with acute coronary syndrome (ACS).

Material And Methods: The study included patients with any type of ACS and obstructive coronary artery disease confirmed by coronary angiography. A quantitative analysis of coronary angiography data was performed with an assessment of the number of CAs with significant stenosis and calculation of the SYNTAX score.

Membrane separation technology has emerged as a highly energy-efficient method for microalgae enrichment and harvesting in wastewater treatment. However, membrane fouling caused by algal cells and stratified extracellular polymeric substances (EPS) remains a critical barrier to its industrial-scale application. This study meticulously investigates the micro process of algae-derived pollutants stacking to the membrane surface affected by stratified EPS.

Per- and polyfluoroalkyl substances (PFAS) in the environment is a growing concern leading to a focus on PFAS occurrence in biosolids, a byproduct of wastewater treatment processes, often applied to improve soil health. This led to the need for analytical method development for assessing PFAS in biosolids. This study compares three methods for PFAS quantitation, evaluating solvent extraction, clean-up techniques, and final injection solvents.
