Plasma cystathionine and risk of incident stroke in patients with suspected stable angina pectoris
(Peer reviewed; Journal article, 2018)Background: Cystathionine is an intermediate product in the transsulfuration pathway and formed during the B6‐dependent conversion of methionine to cysteine. Elevated plasma cystathionine has been related to atherosclerosis, ... -
Plasma density gradients at the edge of polar ionospheric holes: the absence of phase scintillation
(Journal article; Peer reviewed, 2020)Polar holes were observed in the high-latitude ionosphere during a series of multi-instrument case studies close to the Northern Hemisphere winter solstice in 2014 and 2015. These holes were observed during geomagnetically ... -
Plasma free choline, betaine and cognitive performance: the Hordaland Health Study
(Peer reviewed; Journal article, 2013-02)Choline and betaine are nutrients involved in one-carbon metabolism. Choline is essential for neurodevelopment and brain function. We studied the associations between cognitive function and plasma concentrations of free ... -
Plasma Glycine and Risk of Acute Myocardial Infarction in Patients With Suspected Stable Angina Pectoris
(Peer reviewed; Journal article, 2015)Background Glycine is an amino acid involved in antioxidative reactions, purine synthesis, and collagen formation. Several studies demonstrate inverse associations of glycine with obesity, hypertension, and diabetes mellitus. ... -
Plasma growth differentiation factor-15 is an independent marker for aggressive disease in endometrial cancer
(Peer reviewed; Journal article, 2019)Objective: Better biomarkers are needed in order to identify patients with endometrial carcinoma at risk of recurrence and who may profit from a more aggressive treatment regimen. Our objective was to explore the applicability ... -
Plasma Inflammatory Biomarkers Are Associated With Poststroke Cognitive Impairment: The Nor-COAST Study
(Journal article; Peer reviewed, 2023)Background: Inflammation is proposed to be involved in the pathogenesis of poststroke cognitive impairment. The aim of this study was to investigate associations between concentrations of systemic inflammatory biomarkers ... -
Plasma levels of guanylins are reduced in patients with Crohn’s disease
(Journal article; Peer reviewed, 2020)Background: Guanylin (GN) and uroguanylin (UGN) are endogenous ligands for the intestinal receptor guanylate cyclase C (GC-C), an important regulator of intestinal fluid homeostasis. Gene expression and protein levels of ... -
Plasma levels of interleukin 27 in falciparum malaria is increased independently of co-infection with HIV: potential immune-regulatory role during malaria
(Journal article; Peer reviewed, 2020)Background The immune response during falciparum malaria mediates both harmful and protective effects on the host; however the participating molecules have not been fully defined. Interleukin (IL)-27 is a pleiotropic ... -
Plasma methionine, choline, betaine, and dimethylglycine in relation to colorectal cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC)
(Peer reviewed; Journal article, 2014-08)Background Disturbances in one carbon metabolism may contribute to carcinogenesis by affecting methylation and synthesis of DNA. Choline and its oxidation product betaine are involved in this metabolism and can serve as ... -
Plasma methylmalonic acid predicts risk of acute myocardial infarction and mortality in patients with coronary heart disease: A prospective 2-cohort study
(Journal article; Peer reviewed, 2023)Background Elevated plasma methylmalonic acid (MMA) is reported in patients with established coronary heart disease (CHD) and is considered a marker of vitamin B12 deficiency. Moreover, MMA-dependent reactions have been ... -
Plasma parasitemia as assessed by quantitative PCR in relation to clinical disease severity in African adults with falciparum malaria with and without HIV co-infection
(Journal article; Peer reviewed, 2020)Purpose When considering malaria disease severity, estimation of parasitemia in erythrocytes is important, but sometimes misleading, since the infected erythrocytes may be sequestered in peripheral capillaries. In African ... -
Plasma protein biomarkers for the detection of pancreatic neuroendocrine tumors and differentiation from small intestinal neuroendocrine tumors
(Journal article; Peer reviewed, 2022)There is an unmet need for novel biomarkers to diagnose and monitor patients with neuroendocrine neoplasms. The EXPLAIN study explores a multi-plasma protein and supervised machine learning strategy to improve the diagnosis ... -
Plasma proteins elevated in severe asthma despite oral steroid use and unrelated to Type-2 inflammation
(Journal article; Peer reviewed, 2022)Rationale Asthma phenotyping requires novel biomarker discovery. Objectives To identify plasma biomarkers associated with asthma phenotypes by application of a new proteomic panel to samples from two well-characterised ... -
Plasma Retinol and Cardiovascular Disease Mortality in the BECAC Population
(Master thesis, 2014-05-15)Background: Observational studies have suggested a possible link between vitamin A and cardiovascular disease mortality risk. However, randomized supplementation trials have failed to show improvement in survival. There ... -
Plasma tumour necrosis factor correlates with mRNA expression of tumour necrosis factor and mitochondrial transcription factors in skeletal muscle in patients with chronic heart failure treated with cardiac resynchronization therapy: potential role in myopathy
(Peer reviewed; Journal article, 2019)Chronic heart failure (CHF) is characterized by inflammation and skeletal muscle myopathy, including impaired fibre type distribution and reduced capillary density, reduced cytochrome oxidase activity and reduced mitochondrial ... -
Plasma unmetabolized folic acid in pregnancy and risk of autistic traits and language impairment in antiseizure medication-exposed children of women with epilepsy
(Journal article; Peer reviewed, 2022)Background: Fetal exposure to unmetabolized folic acid (UMFA) during pregnancy may be associated with adverse neurodevelopment. Antiseizure medication (ASM) may interact with folate metabolism. Women with epilepsy using ... -
Plasma-derived exosome-like vesicles are enriched in lyso-phospholipids and pass the blood-brain barrier
(Journal article; Peer reviewed, 2020)Exosomes are vesicles involved in intercellular communication. Their membrane structure and core content is largely dependent on the cell of origin. Exosomes have been investigated both for their biological roles and their ... -
