Improved Hematology Analysis Based on Microfluidic Impedance Spectroscopy: Erythrocyte Orientation and Anisotropic Dielectric Properties of Flowing Blood.
Anal Chem
January 2025
School of Mechanical and Robotics Engineering, Gwangju Institute of Science and Technology (GIST), Gwangju 61005, Republic of Korea.
Electrochemical impedance spectroscopy has great potential for laboratory blood tests. The overall aim of this study is to develop a microfluidic sensor for determining the physical properties and hematological parameters of blood based on its dielectric spectra. Impedance was measured in flowing blood to prevent aggregation and sedimentation at frequencies between 40 Hz and 110 MHz.

When an electric field is applied to or removed from colloidal particle aqueous dispersions, a reversible increase in sedimentation velocity of the colloidal particles, referred to as the Electrically Induced Rapid Separation (ERS) effect, is observed. While electrophoresis and other interfacial electrokinetic phenomena under applied electric fields are well-studied, the phenomena of particle aggregation and re-dispersion caused by the application and removal of the field remain largely unexplored despite their significance. Experiments using mixed aqueous dispersions of poly (methyl methacrylate) (PMMA) particles of different sizes revealed that applying an electric field induced the formation of co-flocs involving both large and small particles, significantly enhancing the sedimentation velocity.

Ethnopharmacological Relevance: Traditional Chinese Medicine (TCM) has great potential and advantages in the treatment of rheumatoid arthritis (RA). Wutou decoction (WTD) was first recorded as a pill in the TCM classical book Synopsis of Prescriptions of the Golden Chamber written by Zhang Zhongjing in the Eastern Han Dynasty (25-220 CE). It has significant therapeutic effects in delaying and reversing RA while improving patients' clinical symptoms, making it the best example of TCM treatment for RA.

Objective: To explore the efficacy and safety of Juan Bi Pill (JBP) in treatment of active rheumatoid arthritis (RA).
Methods: From February 2017 to May 2018, 115 participants from 4 centers were randomly divided into JBP group (57 cases) and placebo group (58 cases) in a 1:1 ratio using a random number table method. Participants received a dose of JBP (4 g, twice a day, orally) combined with methotrexate (MTX, 10 mg per week) or placebo (4 g, twice a day, orally) combined with MTX for 12 weeks.
Hydrodynamic Equations for Space-Inhomogeneous Aggregating Fluids with First-Principle Kinetic Coefficients.
Phys Rev Lett

Skolkovo Institute of Science and Technology, 121205 Moscow, Russia.
We derive from the first principles new hydrodynamic equations-Smoluchowski-Euler equations for aggregation kinetics in space-inhomogeneous fluids with fluxes. Starting from Boltzmann equations, we obtain microscopic expressions for aggregation rates for clusters of different sizes and observe that they significantly differ from currently used phenomenological rates. Moreover, we show that for a complete description of aggregating systems, novel kinetic coefficients are needed.
