OBJECTIVE Coronary stent thrombosis is a devastating complication after percutaneous coronary intervention (PCI). The mechanisms underlying stent thrombosis are multifactorial. Whether the coagulation system is involved in the pathophysiology of stent thrombosis is unclear. We hypothesised that thrombin generation, reflecting the coagulation potential, is enhanced in patients with stent thrombo...

Treatments for disease in the central nervous system (CNS) are limited because of difficulties agent penetration through blood-brain barrier, achieving optimal dosing, and mitigating off-target effects. The prospect precision medicine CNS treatment suggests an opportunity therapeutic nanotechnology, which offers tunability adaptability to address specific diseases as well targetability when com...

A misguided inflammatory response is frequently implicated in myelin damage. Particularly prominent among myelin diseases, multiple sclerosis (MS) is an autoimmune condition, with immune-mediated damage central to its etiology. Nevertheless, a robust inflammatory response is also essential for the efficient regeneration of myelin sheaths after such injury. Here, we discuss the functions of infl...

By WILLIArsI H. CROSBY AND NAOMI R. BENJAMIN I HE RED BLOOD CELLS of patients with paroxysmal nocturnal hemoglobinuria ( PNH ) possess an apparently unique susceptibility to the hemolytic activity of certain naturally occurring plasma factors. Hemolysis occurs readily in vitro and the reaction is intensified when the incubating mixture has been made slightly acid. This phenomenon is the basis o...

Background: Direct thrombin inhibitors and factor Xa inhibitors are gaining popularity as alternatives to warfarin for patients requiring anticoagulation. Toxicity due to these medications is difficult to manage because overdose experience is very limited and there is no clear guidance on when or whether to use antidote in this setting. Case Presentation: A 50-year-old man with normal renal fu...

The CNS (central nervous system) is unquestionably the central organ that regulates directly or indirectly all physiological systems in the mammalian body. Yet, when considering the defence of the CNS from pathogens, the CNS has often been considered passive and subservient to the pro-inflammatory responses of the immune system. In this view, neuroinflammatory disorders are examples of when the...

The present data disagree with earlier suggestions that thrombin's effect on platelets is to cause a decrease in intracellular cyclic 3',5'-adenosine monophosphate. Washed human platelets or platelet-rich plasma were incubated at 37 degrees C with human thrombin. After centrifugation, the supernates were assayed for nucleotides and calcium released. The platelet pellets, and in some experiments...

The folding of aptamer immobilized on an Au electrode was successfully detected using label-free electrochemical methods. A thrombin binding DNA aptamer was used as a model system in the presence of various monovalent cations. Impedance spectra showed that the extent to which monovalent cations assist in folding of aptamer is ordered as K(+) > NH(4)(+) > Na(+) > Cs(+). Our XPS analysis also sho...

The inhibition of thrombin is one of the important treatments of pathological blood clot formation. Variegin, isolated from the tropical bont tick, is a novel molecule exhibiting a unique 'two-modes' inhibitory property on thrombin active site (competitive before cleavage, noncompetitive after cleavage). For the better understanding of its function, we have determined the crystal structure of t...

The complement pathway is a major component of the innate immune system, which critical for recognizing and clearing pathogens that rapidly react to defend body against external pathogens. Many components this are expressed throughout brain play beneficial role in synaptic pruning developing central nervous system (CNS). However, excessive complement-mediated aging or injured may contributing w...
