Prednisolone in Dogs-Plasma Exposure and White Blood Cell Response.

Frontiers in veterinary science

Ekstrand C, Pettersson H, Gehring R, Hedeland M, Adolfsson S, Lilliehöök I.
PMID: 34179161
Front Vet Sci. 2021 Jun 09;8:666219. doi: 10.3389/fvets.2021.666219. eCollection 2021.

Glucocorticoids such as prednisolone are commonly used in dogs but there is sparse quantitative pharmacokinetic and pharmacodynamic information of this drug in this species. The objective of this study was to quantitatively characterize the concentration-effect relationship for prednisolone in...

Etherglycerophospholipids and ferroptosis: structure, regulation, and location.

Trends in endocrinology and metabolism: TEM

Balgoma D, Hedeland M.
PMID: 34481732
Trends Endocrinol Metab. 2021 Dec;32(12):960-962. doi: 10.1016/j.tem.2021.08.005. Epub 2021 Sep 01.

Two pioneering studies by Zou et al. and Cui et al. have reported that the synthesis of etherglycerophospholipids (etherPLs) sensitizes cells to ferroptosis. The location and regulation of etherPLs suggest that: (i) lipid peroxidation in the inner leaflet of...

Regional Intestinal Drug Permeability and Effects of Permeation Enhancers in Rat.

Pharmaceutics

Dahlgren D, Cano-Cebrián MJ, Olander T, Hedeland M, Sjöblom M, Lennernäs H.
PMID: 32182653
Pharmaceutics. 2020 Mar 08;12(3). doi: 10.3390/pharmaceutics12030242.

Sufficient colonic absorption is necessary for all systemically acting drugs in dosage forms that release the drug in the large intestine. Preclinically, colonic absorption is often investigated using the rat single-pass intestinal perfusion model. This model can determine intestinal...

Early Risk Factors of Moderate/Severe Hepatotoxicity After Suicide Attempts With Acetaminophen in 11- to 15-Year-Old Children.

Global pediatric health

Hedeland RL, Christensen VB, Jørgensen MH, Teilmann G, Iskandar A, Andersen J.
PMID: 27335908
Glob Pediatr Health. 2014 Oct 14;1:2333794X14552897. doi: 10.1177/2333794X14552897. eCollection 2014.

Objective. To characterize early risk factors of moderate/severe hepatotoxicity in a pediatric population with acetaminophen overdose, due to suicide attempt, admitted to a general secondary-level pediatric department. Methods. A retrospective case study of 107 patients, 11 to 15 years...

Automated Sequential Analysis of Hydrophilic and Lipophilic Fractions of Biological Samples: Increasing Single-Injection Chemical Coverage in Untargeted Metabolomics.

Metabolites

Pirttilä K, Laurell G, Pettersson C, Hedeland M.
PMID: 34063084
Metabolites. 2021 May 05;11(5). doi: 10.3390/metabo11050295.

In order to increase metabolite coverage in LC-MS-based untargeted metabolomics, HILIC- and RPLC-mode separations are often combined. Unfortunately, these two techniques pose opposite requirements on sample composition, necessitating either dual sample preparations, increasing needed sample volume, or manipulation of...

Improved Sensitivity in Hydrophilic Interaction Liquid Chromatography-Electrospray-Mass Spectrometry after Removal of Sodium and Potassium Ions from Biological Samples.

Metabolites

Erngren I, Nestor M, Pettersson C, Hedeland M.
PMID: 33804267
Metabolites. 2021 Mar 15;11(3). doi: 10.3390/metabo11030170.

Inorganic ions, such as sodium and potassium, are present in all biological matrices and are sometimes also added during sample preparation. However, these inorganic ions are known to hamper electrospray ionization -mass spectrometry (ESI-MS) applications, especially in hydrophilic interaction...

The In Vivo Effect of Transcellular Permeation Enhancers on the Intestinal Permeability of Two Peptide Drugs Enalaprilat and Hexarelin.

Pharmaceutics

Dahlgren D, Sjöblom M, Hedeland M, Lennernäs H.
PMID: 31991924
Pharmaceutics. 2020 Jan 26;12(2). doi: 10.3390/pharmaceutics12020099.

Permeation enhancers like sodium dodecyl sulfate (SDS) and caprate increase the intestinal permeability of small model peptide compounds, such as enalaprilat (349 Da). However, their effects remain to be investigated for larger low-permeability peptide drugs, such as hexarelin (887...

Effect of paracellular permeation enhancers on intestinal permeability of two peptide drugs, enalaprilat and hexarelin, in rats.

Acta pharmaceutica Sinica. B

Dahlgren D, Olander T, Sjöblom M, Hedeland M, Lennernäs H.
PMID: 34221875
Acta Pharm Sin B. 2021 Jun;11(6):1667-1675. doi: 10.1016/j.apsb.2020.12.019. Epub 2021 Jan 05.

Transcellular permeation enhancers are known to increase the intestinal permeability of enalaprilat, a 349 Da peptide, but not hexarelin (887 Da). The primary aim of this paper was to investigate if paracellular permeability enhancers affected the intestinal permeation of...
