Understanding the Vicious Circle of Pain, Physical Activity, and Mental Health in Lipedema Patients-A Response Surface Analysis.

Lipedema is a widespread disease with painful accumulations of subcutaneous fat in the legs and arms. Often, obesity co-occurs. Many patients suffer from impairment in mobility and mental health.

Modulation of Beta-Adrenergic Autoantibodies Over Time in Post-Viral ME/CFS is Related to Fatigue and Pain Symptoms.

Background: Myalgic encephalomyelits/chronic fatigue syndrome (ME/CFS) is an acquired disease with symptoms of fatigue and pain. In pathogenesis, the induction of autoantibodies (AAB) against G-protein coupled receptors (GPCR), such as β-adrenergic receptors (β-AdR), has been suspected. GPCR-AAB correlate with symptom severity and autonomic dysfunction in ME/CFS.

Activated monocytes capture platelets for heterotypic association in patients with severe carotid artery stenosis.

Inflammation and thrombosis, two processes influencing each other, are involved in the pathogenesis of cerebrovascular disease. We showed that in patients with acute ischaemic stroke circulating platelets are activated and exhausted. To identify whether activated haemostasis might be cause or effect, we investigated the role of leukocyte and platelet activation in patients with severe asymptomatic and symptomatic carotid artery disease.

Microembolic signals on transcranial Doppler ultrasound are correlated with platelet activation markers, but not with platelet-leukocyte associates: a study in patients with acute stroke and in patients with asymptomatic carotid stenosis.

Background: The in vivo correlates of microembolic signals (MES) are still unknown. Platelet-associates (PA) with monocytes or granulocytes or platelet aggregates only may represent these correlates.

Methods: Thirty patients with asymptomatic carotid stenosis >50% and 16 patients with acute (<4 days) atherothrombotic stroke were investigated.

Platelets in patients with acute ischemic stroke are exhausted and refractory to thrombin, due to cleavage of the seven-transmembrane thrombin receptor (PAR-1).

Platelet activation is involved in the pathogenesis of cerebrovascular ischemia, but the major agonist involved has yet to be identified. To investigate the role of thrombin in platelet activation in patients with acute ischemic stroke, and while thrombin is the most likely candidate for activation of the thrombin receptor PAR-1 in vivo, we assessed its cleavage and internalization using the antibodies SPAN12, binding to uncleaved PAR-1, and WEDE15, recognizing cleaved and uncleaved, but not internalized PAR-1. In contrast to healthy age-matched controls, platelets from stroke patients exhibited significant cleavage and internalization of PAR-1 (P<0.
