THE ACTIVATION OF PLASMINOGEN BY CHLOROFORM [PDF]

Journal of General Physiology, 1946
1. Treatment of serum with chloroform results in immediate inactivation of the protease inhibitor present. 2. Following a lag period of less than one to several days, proteolytic activity begins to appear in the chloroform-treated serum. Activity increases over a period of several days and then begins to diminish gradually.

Tissue plasminogen activator and urokinase plasminogen activator in human epileptogenic pathologies [PDF]

Neuroscience, 2010
A growing body of evidence demonstrates the involvement of plasminogen activators (PAs) in a number of physiologic and pathologic events in the CNS. Induction of both tissue plasminogen activator (tPA) and urokinase plasminogen activator (uPA) has been observed in different experimental models of epilepsy and tPA has been implicated in the mechanisms ...

THE RELEASE OF PLASMINOGEN ACTIVATORS FROM SPERMATOZOA DURING ACROSOME REACTION

, 1992
PLASMINOGEN ACTIVATORS ARE ENZYMES THAT CONVERT THE PROENZYME PLASMINOGEN TO THE TRYPSIN-LIKE PROTEINASE PLASMIN. PLASMINOGEN ACTIVATORS AND PLASMIN ARE REGULATED BY SEVERAL PLASMINOGEN ACTIVATOR INHIBITORS AND PLASMIN INHIBITORS, RESPECTIVELY. IN

Co‐Delivery of Sustained Release Chondroitinase ABC‐37 With Human iPSC‐Derived Neural Progenitors Promotes Transplant Survival and Functional Recovery in a Rodent Model of Stroke

Advanced Science, EarlyView.
A regenerative strategy for stroke combines human stem cell–derived neural progenitor cells with sustained release of a matrix‐modifying, thermostable chondroitinase ABC‐37 enzyme. In a rat model of stroke, co‐delivery enhanced transplanted cell survival and neuronal differentiation, degraded inhibitory extracellular matrix components, and improved ...

Engineered Brain‐Targeted Exosomes Delivering FGF1 for Sustained Glycemic Regulation and Multitarget Neurovascular Protection in Diabetic Stroke

Advanced Science, Volume 13, Issue 61, 3 November 2026.
ABSTRACT Diabetic stroke is characterized by a hyperglycemic and pro‐inflammatory microenvironment that exacerbates neurovascular dysfunction. However, the blood–brain barrier (BBB) remains a formidable obstacle, restricting the delivery of most therapeutic molecules.

Lack of durable protection against cotton smoke-induced acute lung injury in sheep by nebulized single chain urokinase plasminogen activator or tissue plasminogen activator

Clinical and Translational Medicine, 2018
Background Airway fibrin casts are clinically important complications of severe inhalational smoke-induced acute lung injury (ISIALI) for which reliable evidence-based therapy is lacking.

Pro-fibrinolytic potential of the third larval stage of Ascaris suum as a possible mechanism facilitating its migration through the host tissues

Parasites & Vectors, 2020
Background Ascaris roundworms are the parasitic nematodes responsible for causing human and porcine ascariasis. Whereas A. lumbricoides is the most common soil-transmitted helminth infecting humans in the world, A.

Nano Proton Scavengers Modulate Endosomal pH to Inhibit Microglial Activation and Enhance Stroke Recovery

Advanced Science, EarlyView.
Amphiphilic sulfonated chitosan nanoparticles buffer endo/lysosomal acidity in microglia by limiting V‐ATPase membrane recruitment and restoring endosomal homeostasis. Following systemic administration, they accumulate in the ischemic hemisphere partly through association with infiltrating immune cells, suppress TLR3/IRF3 and TLR4/NF‐κB signaling ...

Relationship Between Language Preference and Intravenous Thrombolysis Among Acute Ischemic Stroke Patients

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
Background Approximately 20% of the US population primarily speaks a language other than English at home. Yet the effect of language preference on treatment of acute ischemic stroke (AIS) patients remains unknown.

SerpinA3 is an Endogenous TGF‐β Receptor Antagonist that Attenuates Cardiac Fibroblast Activation and Fibrotic Remodeling

Advanced Science, EarlyView.
SerpinA3 acts as an endogenous TGF‐β receptor antagonist that binds to the extracellular domain of TGFR‐1, thereby preventing TGFR‐1–TGFR‐2 complex formation. This receptor‐level blockade suppresses TGF‐β/Smad2/3 signaling, attenuates cardiac fibroblast activation, and extracellular matrix deposition, and ultimately alleviates pressure overload–induced
