Crystal structure and functional characterization of an Asp49 phospholipase A2 from the bushmaster (Lachesis muta)

Acta Crystallographica Section F, EarlyView.
The crystal structure of an Asp49 phospholipase A2 from L. muta is reported, revealing a tetrameric assembly, catalytic conservation and a polarized electrostatic surface potentially linked to membrane targeting.Snake‐venom phospholipases A2 (PLA2s) are small, structurally conserved enzymes that contribute significantly to the pathophysiology of ...

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.

Meta-Analysis of Preclinical Studies of Fibrinolytic Therapy for Acute Lung Injury

Frontiers in Immunology, 2018
BackgroundAcute lung injury (ALI) is characterized by suppressed fibrinolytic activity in bronchoalveolar lavage fluid (BALF) attributed to elevated plasminogen activator inhibitor-1 (PAI-1).

Renal‐vascular axis: unmasking its role in vascular endothelial growth factor‐inhibitor vascular toxicity in cancer patients

British Journal of Pharmacology, EarlyView.
Abstract Vascular toxicity is a growing concern in cancer patients receiving vascular endothelial growth factor inhibitor (VEGFi) therapy, posing a significant threat to patient prognosis. While the primary mechanism of VEGFi‐induced vascular toxicity is linked to redox‐sensitive reactions that disrupt vascular tone, leading to hypertension and ...

ST-Elevation myocardial infarction network: systematization in 205 cases reduced clinical events in the public health care system [PDF]

, 2012
BACKGROUND: The major cause of death in the city of São Paulo (SP) is cardiac events. At its periphery, in-hospital mortality in acute myocardial infarction is estimated to range between 15% and 20% due to difficulties inherent in large metropoles ...

Rare Bleeding Disorders and Bleeding Disorder of Unknown Cause: Current Understanding and Recent Developments

Haemophilia, EarlyView.
ABSTRACT Rare bleeding disorders (RBDs) represent a diverse group of inherited conditions involving coagulation factors or platelets. These conditions, such as Glanzmann thrombasthenia (GT) or severe coagulation factor deficiencies, are uncommon. In contrast, bleeding disorder of unknown cause (BDUC) is a diagnosis of exclusion without an identifiable ...

Anti-fibrinolytic agents in post partum haemorrhage: a systematic review

BMC Pregnancy and Childbirth, 2009
Background Post partum haemorrhage is a leading cause of maternal death worldwide. It also contributes to maternal morbidity as women may require a hysterectomy to control bleeding, or may require a blood transfusion, which can transmit viral infections.

Immune endotypes in tuberculosis: Keys to decoding disease complexity

Journal of Internal Medicine, EarlyView.
Abstract Tuberculosis (TB) remains a major global health challenge, with multi‐drug antibiotic regimens as the current standard of care. While effective at killing Mycobacterium tuberculosis, these treatments do not resolve persistent inflammation, prevent lung damage, or reverse immune dysregulation that contribute to poor outcomes and disease ...

Degradation of connective tissue matrices by macrophages. III. Morphological and biochemical studies on extracellular, pericellular, and intracellular events in matrix proteolysis by macrophages in culture. [PDF]

, 1980
We have shown that macrophages in culture degrade the glycoproteins and amorphous elastin of insoluble extracellular matrices. Ultrastructural observation of the macrophage-matrix interaction revealed that connective tissue macromolecules were ...

Estrogen as a therapeutic agent: Targeting endotheliopathy and coagulopathy in trauma

Transfusion, EarlyView.
Abstract Background Traumatic injury remains a leading cause of death, often due to uncontrolled hemorrhage and trauma‐induced coagulopathy (TIC). TIC is critically triggered by the endotheliopathy of trauma, involving endothelial cell injury and glycocalyx degradation. Despite conventional advances, the stable casualty rate underscores the urgent need
