Use of ultrasound attenuation spectroscopy to determine the size distribution of clay tactoids in aqueous suspensions

open access: yes, 2013
The dispersion processes of aqueous samples of clay are studied using ultrasound attenuation spectroscopy. The attenuation spectra that are acquired in the frequency range $10-100$ MHz are used to determine the particle size distributions (PSDs) for ...

A Morphological Approach to the Pulsed Emission from Soft Gamma Repeaters [PDF]

open access: yes, 2008
We present a geometrical methodology to interpret the periodical light curves of Soft Gamma Repeaters based on the magnetar model and the numerical arithmetic of the three-dimensional magnetosphere model for the young pulsars.

Implementation of helicase-dependent amplification with SYBR Green I for prompt naked-eye detection of bacterial contaminants in platelet products

open access: yesScientific Reports, 2023
Platelet transfusions may lead to more significant risks of infection and septic transfusion reactions that can be fatal to the recipient. Platelet products should be screened to limit or detect bacterial contamination before application to patients to ...

Serotonin reuptake inhibitors and cardiovascular disease [PDF]

open access: yes, 2005
Selective serotonin re-uptake inhibiting drugs (SSRIs) are widely used for endogenous depression. In addition to depleting the nerve terminals of serotonin they also lower blood platelet serotonin levels.

In Vitro Effect of Dexmedetomidine on Platelet Aggregation

open access: yesBrazilian Journal of Anesthesiology, 2013
Background and objectives: : Dexmedetomidine is a selective α2-agonist. There are 250-300 α2- adrenoceptor on the surface of each human platelet and ephedrine induces platelet aggregation by binding these receptors.

Semi-synthetic preparation of 1-O-[1'-14C]hexadecyl-2-acetyl-sn-glycero-3-phosphocholine (platelet activating factor) using plant cell cultures.

open access: yesJournal of Lipid Research, 1985
Incubation of photomixotrophic cell suspension cultures of rape (Brassica napus) and heterotrophic cell suspension cultures of soya (Glycine max) with 1-O-[1'-14C]hexadecyl-sn-glycerol or rac-1-O-[1'-14C]hexadecylglycerol leads in high yield (up to 78 ...

Cu,Zn,Al layered double hydroxides as precursors for copper catalysts in methanol steam reforming – pH-controlled synthesis by microemulsion technique [PDF]

open access: yes, 2012
By co-precipitation inside microemulsion droplets a Cu-based catalyst precursor was prepared with a Cu:Zn:Al ratio of 50:17:33. A pH-controlled synthesis was applied by simultaneous dosing of metal solution and precipitation agent.

Platelet Gene Expression as a Biomarker Risk Stratification Tool in Acute Myocardial Infarction: A Pilot Investigation

open access: yesClinical Medicine Insights: Blood Disorders, 2010
Platelets play a major role in the pathophysiology of acute myocardial infarction (AMI). Recent evidence reveals megakaryocyte-derived platelet pre-mRNA is spliced to mRNA and then translated into functional proteins in response to external stimulation ...

Comparison of plateletpheresis on three continuous flow cell separators

open access: yesAsian Journal of Transfusion Science, 2009
Introduction: Platelet concentrate (PC) remains one of the most important support measures in thrombocytopenic patients. An efficient cell separator is a prerequisite for an optimally functioning apheresis setup.
