We previously showed microvascular alteration of both endothelium-dependent and -independent reactivity after a single SCUBA dive. We aimed to study mechanisms involved in this postdive vascular dysfunction. Ten divers each completed three protocols: (1) a SCUBA dive at 400...

BACKGROUND: Inorganic pyrophosphate (PPi) plays a major role inhibiting dystrophic calcification. The aim was to analyze levels of PPi in patients having pseudoxanthoma elasticum (PXE), and controls as well as the enzymes who regulate the PPi plasma concentration.METHODS: We...

Pulsed Radiofrequency Neuromodulation Contributes to Activation of Platelet-Rich Plasma in In Vitro Conditions.

Neuromodulation : journal of the International Neuromodulation Society

Michno A, Kirkor Z, Gojtowska E, Suchorzewski M, Śmietańska I, Baścik B.
PMID: 32027438
Neuromodulation. 2020 Feb 06; doi: 10.1111/ner.13105. Epub 2020 Feb 06.

OBJECTIVES: Recent years have brought new developments in interventional chronic pain management, namely regenerative orthopedics utilizing platelet-rich plasma (PRP) as well as further evolution of pulsed radiofrequency neuromodulation (PRF). Both methods have been used separately. Here, we investigated whether...

PMID: 29296696
Blood Adv. 2016 Nov 22;1(1):62-74. doi: 10.1182/bloodadvances.2016000877. eCollection 2016 Nov 29.

Heparin-induced thrombocytopenia (HIT) is a thrombotic disorder initiated by antibodies to complexes between platelet factor 4 (PF4) and heparin. The risk of recurrent thromboembolism persists after heparin is cleared and platelet activation leading to release of PF4 has dissipated....

Exploring the Extracellular Regulation of the Tumor Angiogenic Interaction Network Using a Systems Biology Model.

Frontiers in physiology

Li D, Finley SD.
PMID: 31379588
Front Physiol. 2019 Jul 18;10:823. doi: 10.3389/fphys.2019.00823. eCollection 2019.

Tumor angiogenesis is regulated by pro- and anti-angiogenic factors. Anti-angiogenic agents target the interconnected network of angiogenic factors to inhibit neovascularization, which subsequently impedes tumor growth. Due to the complexity of this network, optimizing anti-angiogenic cancer treatments requires detailed...

Response to The challenges of diagnosing heparin-induced thrombocytopenia in patients with COVID-19.

Research and practice in thrombosis and haemostasis

Riker RR, May TL, Fraser GL, Gagnon DJ, Bandara M, Zemrak W, Seder DB.

We thank May et al for their comments, expanding the number of reported cases of suspected and confirmed heparin-induced thrombocytopenia (HIT) associated with COVID-19, and reemphasizing the complexity of the prothrombotic state observed (1). We agree that false-positive enzyme...

Trends Cardiovasc Med. 2021 Aug 27; doi: 10.1016/j.tcm.2021.08.012. Epub 2021 Aug 27.

In coronavirus disease 2019 (COVID-19), multiple thromboinflammatory events contribute to the pathophysiology, including coagulation system activation, suppressed fibrinolysis, vascular endothelial cell injury, and prothrombotic alterations in immune cells such as macrophages and neutrophils. Although thrombocytopenia is not an initial...
