Defining an Optimal Range of Centrifugation Parameters for Canine Semen Processing

Animals, 2023
Our objective was to determine a clinically relevant range of centrifugation parameters for processing canine semen. We hypothesized that higher gravitational (g) force and longer time of centrifugation would result in improved spermatozoa recovery rate (

Circulating Cell-Free DNA and RNA Analysis as Liquid Biopsy: Optimal Centrifugation Protocol

Cancers, 2019
The combined analysis of circulating cell-free (tumor) DNA (cfDNA/ctDNA) and circulating cell-free (tumor) RNA (cfRNA/ctRNA) shows great promise in determining the molecular profile of cancer patients. Optimization of the workflow is necessary to achieve

THE DETERMINATION OF KINETIC REGULARITIES OF SEPARATION OF WATER-EMULSION SPINACH SUSPENSION IN THE FIELD OF GRAVITATIONAL AND CENTRIFUGAL FORCES

Современная наука и инновации, 2022
Chlorophyll is a green plant pigment that is highly soluble in fats. This pigment substance, called the food dye chlorophyll and related to food premixes, is obtained by various physicochemical methods from raw materials, usually of plant origin.

Distribution of chromaffin secretory vesicles, acetylcholinesterase, and lysosomal enzymes in sucrose and percoll gradients [PDF]

, 1984
Crude chromaffin secretory vesicles, obtained by differential centrifugation, were further purified on isotonic (Percoll) gradients. The chromaffin vesicle fractions recovered from the gradients contain acetylcholinesterase as well as lysosomal enzymes ...

Effect of treatments and washing cycles on the quality of Nile tilapia (Oreochromis niloticus) protein concentrate

Journal of Fisheries, 2017
The extraction of proteins from wastes reduces production costs and environmental pollution. The aim of this work was to evaluate the effect of two treatments involving decanting/sieving or centrifugation and the number of washing cycles on the quality ...

Puromycin Sensitivity of Ribosomal Label after Incorporation of 14C-Labelled Amino Acids into Isolated Mitochondria from Neurospora crassa [PDF]

, 1969
Radioactive amino acids were incorporated into isolated mitochondria from Neurospora crassa. Then the mitochondrial ribosomes were isolated and submitted to density gradient centrifugation. A preferential labelling of polysomes was observed.

Reduction of relative centrifugal forces increases growth factor release within solid platelet-rich-fibrin (PRF)-based matrices: a proof of concept of LSCC (low speed centrifugation concept)

European Journal of Trauma and Emergency Surgery, 2017
Purpose The present study evaluated the platelet distribution pattern and growth factor release (VEGF, TGF-β1 and EGF) within three PRF (platelet-rich-fibrin) matrices (PRF, A-PRF and A-PRF+) that were prepared using different relative centrifugation ...
