Use of superheated liquids for the extraction of non-volatile compounds from wood: HPLC studies [PDF]

, 2004
A study of the extraction of oak wood compounds using superheated water-ethanol mixtures ranging from 10 to 60% ethanol is reported. Identification and characterization of the extracted compounds have been made by high performance liquid chromatography ...

Making tau amyloid models in vitro: a crucial and underestimated challenge

FEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Oral Substitution of Melatonin in Critical Care: A Pharmacokinetic Study in Patients with Intracranial Hemorrhage

Journal of Pharmaceutical Care, 2020
Background: Intracranial hemorrhage (ICH) is a devastating condition with a high mortality and morbidity rate. Neuroprotective agents protect surrounding brain tissue from the toxic effects of hematoma and can result in better outcomes. There is evidence

Surfaceome: a new era in the discovery of immune evasion mechanisms of circulating tumor cells

Molecular Oncology, EarlyView.
In the era of immunotherapies, many patients either do not respond or eventually develop resistance. We propose to pave the way for proteomic analysis of surface‐expressed proteins called surfaceome, of circulating tumor cells. This approach seeks to identify immune evasion mechanisms and discover potential therapeutic targets. Circulating tumor cells (

Influence of telopeptides on the structural and physical properties of polymeric and monomeric acid-soluble type I collagen [PDF]

, 2017
Currently two factors hinder the use of collagen as building block of regenerative devices: the potential antigenicity, and limited mechanical strength in aqueous environment. Polymeric collagen is naturally found in the cross-linked state and is mechanically tougher than the monomeric, cross-link-free (acid-soluble) collagen ex vivo.

Adaptation of the Bridgman anvil cell to liquid pressure mediums [PDF]

Rev. Sci. Instrum. 78, 123901 (2007), 2008
The advantage of Bridgman anvil pressure cells is their wide pressure range and the large number of wires which can be introduced into the pressure chamber. In these pressure cells soft solid pressure mediums like steatite are used. We have succeeded in adapting the Bridgman cell to liquid pressure mediums.

Superheated liquids for the extraction of solid residues from winemaking processes [PDF]

, 2003
Solid residues from winemaking process have been subjected to extraction with superheated water-ethanol mixtures. Identification and characterisation of the extracted compounds have been made by spectrophotometry, gas chromatography with either flame ...

Prediction of peptide retention times in high-pressure liquid chromatography on the basis of amino acid composition.

Proceedings of the National Academy of Sciences of the United States of America, 1980
Analysis of peptides by reverse-phase high-pressure liquid chromatography would be simplified if retention times could be predicted by summing the contribution to retention of each of the peptide's amino acid side chains.

On‐treatment dynamics of circulating extracellular vesicles in the first‐line setting of patients with advanced non‐small cell lung cancer: the LEXOVE prospective study

Molecular Oncology, EarlyView.
The LEXOVE prospective study evaluated plasma cell‐free extracellular vesicle (cfEV) dynamics using Bradford assay and dynamic light scattering in metastatic non‐small cell lung cancer patients undergoing first‐line treatments, correlating a ∆cfEV < 20% with improved median progression‐free survival in responders versus non‐responders.

Is high pressure liquid chromatography an effective screening tool for characterization of molecular defects in hemoglobinopathies?

Indian Journal of Pathology and Microbiology, 2013
Introduction: Hemoglobinopathies constitute entities that are generated by either abnormal hemoglobin or thalassemias. high pressure liquid chromatography (HPLC) is one of the best methods for screening and detection of various hemoglobinopathies but it ...
