Low-Density Granulocyte Contamination From Peripheral Blood Mononuclear Cells of Patients With Sepsis and How to Remove It – A Technical Report

Frontiers in Immunology, 2021
Elucidating the mechanisms contributing to the dysregulated host response to infection as part of the syndrome is a current challenge in sepsis research. Peripheral blood mononuclear cells are widely used in immunological studies.

Continuous Percoll Gradient Centrifugation of Erythrocytes—Explanation of Cellular Bands and Compromised Age Separation

Cells, 2022
(1) Background: When red blood cells are centrifuged in a continuous Percoll-based density gradient, they form discrete bands. While this is a popular approach for red blood cell age separation, the mechanisms involved in banding were unknown.

Smooth-Particle Phase Stability with density and density-gradient potentials [PDF]

, 2005
Stable fluid and solid particle phases are essential to the simulation of continuum fluids and solids using Smooth Particle Applied Mechanics. We show that density-dependent potentials, such as Phi=(1/2)Sum (rho-rho_0)^2, along with their corresponding ...

Does choosing microfluidics for sperm sorting offer an advantage to improve clinical pregnancies in donor egg recipients?

Journal of Human Reproductive Sciences, 2022
Background: Microfluidics (MF), an advanced sperm sorting technology results in the extraction of spermatozoa with higher DNA integrity and lower DNA damage compared to existing conventional sperm sorting methods. Aims: The aim of the present study is to

Simulation of direct source-to-drain tunnelling using the density gradient formalism: Non-Equilibrium Greens Function calibration [PDF]

, 2002
Quantum mechanical confinement effects, gate, hand-to-hand and source-to-drain tunnelling will dramatically affect the characteristics of future generation nanometre scaled devices.

ASSESSMENT OF GAS-HYDROTHERMAL ACTIVITY OF THE BAIKAL RIFT IN THE LAKE AREA FROM NUMERICAL EXPERIMENT DATA

Геодинамика и тектонофизика, 2015
The Baikal rift is characterized by high heat flow, seismic activity and large thickness of sediments through which gas and hydrothermal water are intensely released into the lake water.

On the Origin of Asymmetries in Bilateral Supernova Remnants [PDF]

, 2007
AIMS: We investigate whether the morphology of bilateral supernova remnants (BSNRs) observed in the radio band is determined mainly either by a non-uniform interstellar medium (ISM) or by a non-uniform ambient magnetic field.

Sperm selection with density gradient centrifugation and swim up: effect on DNA fragmentation in viable spermatozoa

Scientific Reports, 2019
Subjects increasing sperm DNA fragmentation (sDF) during Density Gradient Centrifugation (DGC), a common sperm selection procedure in Assisted Reproduction Techniques (ARTs), experience a 50% lower probability of pregnancy. Hence, identification of these

Efficacy of two sperm preparation techniques in reducing non-specific bacterial species from human semen

Journal of Human Reproductive Sciences, 2013
Context: Artificial reproductive techniques using seminal preparations with bacteria may cause pelvic inflammatory disease and its sequalae. Aims: To assess efficacy of two sperm preparation techniques to clear bacteria and the effect of bacteriospermia ...

Detection of geological boundaries by 3D gravity inversion for density gradients in different directions

Frontiers in Earth Science, 2022
The spatial position and dip feature of the density boundary are significant to the study of fault and tectonic frameworks. Edge detection methods generally attach importance to the horizontal position of the boundary, but it is difficult to determine ...
