Contact Activation Is Alleviated by Testosterone Replacement Therapy in Klinefelter Syndrome: Evidence of Hormonal and Metabolic Modulation

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome is associated with a markedly increased risk of venous thrombosis. While hypogonadism and metabolic dysfunction are known contributors, the role of the contact activation system in Klinefelter syndrome remains unexplored.

Intracellular proteolysis of kininogen by malaria parasites promotes release of active kinins

Malaria Journal, 2012
Background The malaria burden remains a major public health concern, especially in sub-Saharan Africa. The complex biology of Plasmodium, the apicomplexan parasite responsible for this disease, challenges efforts to develop new strategies to control the ...

Biochemistry, molecular genetics, and clinical aspects of hereditary angioedema with and without C1 inhibitor deficiency

Allergology International, 2023
Hereditary angioedema (HAE) is a rare disorder characterized by cutaneous and submucosal swelling caused mostly by excessive local bradykinin production.

Biomarkers Correlating With the Development of Oral Squamous Cell Carcinoma From Leukoplakia

Oral Diseases, EarlyView.
ABSTRACT Background We assessed protein biomarkers expressed in oral leukoplakia (OL) that are associated with the risk of transformation into oral squamous cell carcinoma (OSCC). Methods Tissue sections of OL transforming into OSCC (leuko‐ca), the corresponding OSCC and OL that did not progress to OSCC (leuko‐nonca) were analyzed with global relative ...

Alterations in the kallikrein-kinin system predict death after heart transplant

Scientific Reports, 2022
Heart transplantation remains the definitive treatment for end stage heart failure. Because availability is limited, risk stratification of candidates is crucial for optimizing both organ allocations and transplant outcomes.

Normal thromboelastography with a markedly prolonged activated partial thromboplastin time in severe prekallikrein deficiency: Implications for perioperative hemostatic assessment

Transfusion, EarlyView.
Abstract Background Prekallikrein (PK) deficiency is a rare contact factor deficiency that can markedly prolong the activated partial thromboplastin time (aPTT) without a bleeding phenotype. Because viscoelastic hemostatic assays also rely on contact activation, their behavior in severe PK deficiency is relevant to perioperative evaluation of isolated ...

Preliminary Evaluation of a Novel Lupus Anticoagulant Activity Assay Unaffected by Anticoagulants

Journal of Clinical Laboratory Analysis, Volume 40, Issue 15, August 2026.
A novel one‐step lupus anticoagulant (LA) assay based on the LA‐sensitivity ratio (LA‐SR) was developed to simplify diagnostic testing and reduce potential interference from anticoagulants. The LA‐SR method showed good agreement with guideline‐based LA testing (dRVVT and/or LA‐sensitive APTT) for the detection of LA and demonstrated limited influence ...

The effect of estrogen-containing birth control pills on the constituents of bradykinin expression in plasma

Journal of Allergy and Clinical Immunology: Global
Background: Hereditary angioedema with C1-inhibitor deficiency (HAE-C1INH) is a rare autosomal disorder presenting with recurrent angioedema. Estrogen-containing medications trigger angioedema in some patients, and conversely, progesterone may decrease ...

Changes in the Glycosylation of Kininogen and the Development of a Kininogen-Based Algorithm for the Early Detection of HCC [PDF]

Cancer Epidemiology, Biomarkers & Prevention, 2017
Abstract Background: Hepatocellular carcinoma (HCC) has the greatest increase in mortality among all solids tumors in the United States related to low rates of early tumor detection. Development of noninvasive biomarkers for the early detection of HCC may reduce HCC-related mortality.

Factor XI Inhibition for Ischemic Stroke Secondary Prevention: Pharmacology, Clinical Evidence, and Future Directions

The Journal of Clinical Pharmacology, Volume 66, Issue 8, August 2026.
Abstract Ischemic stroke remains a leading cause of death and disability worldwide, and bleeding (particularly intracranial hemorrhage) continues to limit conventional antithrombotic therapy in secondary prevention, even with direct oral anticoagulants.
