A targeted apoB38.9 mutation in mice is associated with reduced hepatic cholesterol synthesis and enhanced lipid peroxidation.
2006
Familial hypobetalipoproteinemia (FHBL) due to truncation-specifying mutations of apolipoprotein B (apoB), which impair hepatic lipid export in very low-density lipoprotein (VLDL) particles, is associated with fatty liver. In an FHBL-like mouse with the apoB38.9 mutation, fatty liver develops despite reduced hepatic fatty acid synthesis. However, hepatic cholesterol contents in apoB38.9 mice are normal. We found that cholesterogenic enzymes (3-hydroxy-3-methylglutaryl-coenzyme A reductase, sterol-C5-desaturase, and 7-dehydrocholesterol reductase) were consistently downregulated in two separate expression-profiling experiments using a total of 19 mice ( n = 7 each for apob+/+and apob+/38.9, …
I´m tired of being tired - Fatigue as experienced by women with fibromyalgia
2011
AbstractThe aim of the study was to explore how fatigue was experienced and explained in life stories of women with a long history of fibromyalgia to gain a deeper understanding of fatigue as a phenomenon. The data was drawn from the narrative interviews of 20 purposively chosen women with fibromyalgia. In the analysis, the ideas of episodic reading and paradigmatic analysis of narratives were used to find recurrent and repeated experiences of fatigue from the data. Five main themes emerged from the data: sleepless nights, physical weakness, loss of mental energy, social withdrawal and overwhelming exhaustion. The narratives indicated that in fibromyalgia, fatigue is a transient, extreme an…
Associations of physical activity, fitness, and body composition with heart rate variability–based indicators of stress and recovery on workdays: a c…
2014
Background. The purpose of this study was to investigate how physical activity (PA), cardiorespiratory fitness (CRF), and body composition are associated with heart rate variability (HRV)-based indicators of stress and recovery on workdays. Additionally, we evaluated the association of objectively measured stress with self-reported burnout symptoms. Methods. Participants of this cross-sectional study were 81 healthy males (age range 26–40 y). Stress and recovery on workdays were measured objectively based on HRV recordings. CRF and anthropometry were assessed in laboratory conditions. The level of PA was based on a detailed PA interview (MET index [MET-h/d]) and self-reported activity class…
Is oxidative stress a therapeutic target in cardiovascular disease?
2010
An abnormal production of reactive oxygen species (ROS) and the subsequent decrease in vascular bioavailability of nitric oxide (NO) have long been proposed to be the common pathogenetic mechanism of the endothelial dysfunction, resulting from diverse cardiovascular risk factors such as hypercholesterolaemia, diabetes mellitus, chronic smoking, metabolic syndrome, and hypertension. Superoxide produced by the nicotinamide dinucleotide phosphate (NADPH) oxidase, mitochondrial sources, or the xanthine oxidase may react with NO, thereby resulting in excessive formation of peroxynitrite, a reactive nitrogen species that has been demonstrated to accelerate the atherosclerotic process by causing d…
Oxidized Albumin and Cartilage Acidic Protein-1 as Blood Biomarkers to Predict Ischemic Stroke Outcomes.
2021
Background: There is high demand for blood biomarkers that reflect the therapeutic response or predict the outcomes of patients with acute ischemic stroke (AIS); however, few biomarkers have been evidentially verified to date. This study evaluated two proteins, oxidized albumin (OxHSA) and cartilage acidic protein-1 (CRTAC1), as potential prognostic markers of AIS.Methods: The ratio of OxHSA to normal albumin (%OxHSA) and the level of CRTAC1 in the sera of 74 AIS patients were analyzed on admission (day 0), and at 1 and 7 days after admission. AIS patients were divided into two groups according to their modified Rankin Scale (mRS) at 3 months after discharge: the low-mRS (mRS < 2) gr…
The Mitochondrial Antioxidant SS-31 Modulates Oxidative Stress, Endoplasmic Reticulum Stress, and Autophagy in Type 2 Diabetes
2019
Mitochondrial dysfunction has been shown to play a central role in the pathophysiology of type 2 diabetes (T2D), and mitochondria-targeted agents such as SS-31 are emerging as a promising strategy for its treatment. We aimed to study the effects of SS-31 on leukocytes from T2D patients by evaluating oxidative stress, endoplasmic reticulum (ER) stress and autophagy. Sixty-one T2D patients and 53 controls were included. Anthropometric and analytical measurements were performed. We also assessed reactive oxygen species (ROS) production, calcium content, the expression of ER stress markers GRP78, CHOP, P-eIF2&alpha
No relationship between baseline salivary alpha-amylase and State-Trait Anxiety Inventory Score in drug-naïve patients with short-illness-duration fi…
2016
BACKGROUND Salivary α-amylase (sAA) activity alternations are observed in major depressive disorder (MDD) being associated with depression severity and its specific psychopathological dimensions with anxiety being attributed to distress. No data is available on sAA in MDD according to Hamilton Rating Scale for Depression (HAMD-17) and State-Trait Anxiety Inventory (STAI). The exploratory study examines whether and to what extent baseline sAA level is interrelated to the psychopathological features including severity of symptoms and specific psychopathological dimensions. MATERIAL AND METHODS The basal, non-stimulated sAA activity was studied in 20 non-late-life adult, treatment-naive MDD pa…
Stress and recovery states after a 24 h ultra-marathon race: A one-month follow-up study
2011
Abstract Objectives The purpose of this study was to investigate the athlete’s perception of stress and recovery states following a 24 h ultra-marathon race. Design and method Psychological states were assessed in 14 male subjects before as well as 1, 3, 6, 9, 12, 15, 21, and 30 days after the race. Results The results suggest an ultra-endurance race induces perceived stress and leads to subsequent alterations in perceived recovery, whatever the psychological, physical, emotional or social dimensions according to a unique time-course for the several components evaluating the stress and recovery process. Stress and recovery levels related to the 24 h race showed that a period of 2 weeks is r…
Deutschsprachige Validierung des Vertigo Handicap Questionnaire (VHQ) anhand einer Patientenstichprobe mit vestibulärem und somatoformem Schwindel
2010
The Vertigo Handicap Questionnaire (VHQ) by Yardley (1992) assesses physical and psychosocial impairments of vertigo or dizziness. Our study examines the structure, reliability, and aspects of validity of the German version of the VHQ. 98 vestibular vertigo syndromes vs. 90 patients with somatoform vertigo and dizziness were evaluated with the VHQ, symptom severity (VSS), distress (GSI), anxiety and depression (HADS), catastrophizing beliefs (ACQ), fear of body sensations (BSQ), and quality of life (SF-36). For diagnostic classification detailed clinical neurological, neuro-otological and psychosomatic testing were conducted. Principal components analysis identified two factors, which could…
SFRR-E Young Investigator AwardeeαB-crystallin modulation after acute exercise in skeletal muscle: the role of oxidative stress and fiber composition.
2015
αB-crystallin (CRYAB) is a member of the small heat shock proteins implicated in various biological functions, particularly in skeletal muscle where it is involved in adaptive remodelling processes, activation of gene transcription and stabilization of nascent proteins.In this research we analysed αB-crystallin' response in mouse gastrocnemius at 15' and 30' of recovery from an acute aerobic exercise (1hour), correlating its modulation with oxidative stress level and fiber composition, red (RG) and white gastrocnemius (WG).We found for the first time that the acute exercise lead to a short term, specific increase of phospho-αB-crystallin level (pCRYAB) in the RG, while no changes were obser…
