Thrombin generation and the pharmacodynamics of parenteral anticoagulants

Parenteral anticoagulants are mainstay therapies in critical care and perioperative settings because of their unique pharmacological properties, but they have a narrow therapeutic window.

Fumarate Hydratase Lactylation Exacerbates Traumatic Brain Injury Pathology via Mitochondrial Dysfunction and Neuroinflammation

Advanced Science, EarlyView.
Tian et al. reveal that FH K112 lactylation is elevated after TBI, leading to fumarate accumulation, mitochondrial damage, mtDNA release and amplified neuroinflammation. AARS2 and SIRT3 act as the “writer” and “eraser” for FH K112 lactylation. The peptide Pep‐K112 targeting this site alleviates brain injury, highlighting a potential therapeutic target.

The Deubiquitinase UCHL1 Drives Susceptibility to Atrial Fibrillation by Stabilizing CaMKII‐δ

Advanced Science, EarlyView.
UCHL1 is highly upregulated in mice and patients with AF. UCHL1 directly binds to and removes K48‐linked polyubiquitin chains from CaMKII‐δ at K251 and enhances CaMKII‐δ stability, which activates RyR2, disrupts Ca2+ handling, and promotes AF. These findings establish UCHL1 as a critical regulator of CaMKII‐δ stability and AF‐related Ca2+ handling ...

Puerarin‑Loaded pH‑Responsive ZIF‑90 Nanoparticles Ameliorate Osteoporosis via Enhancing H3K18 Lactylation and Suppressing Aberrant Osteoclast Activation

Advanced Science, EarlyView.
Schematic illustration of the mechanism by which ZIF‐90@PU alleviates osteoporosis via H3K18la‐mediated NFATc1 pathway suppression. ABSTRACT Osteoporosis is characterized by dysregulated osteoclast activity, leading to excessive bone resorption and structural damage.

Comparative Analysis of Antithrombotic Therapy Outcomes in Mild Traumatic Brain-Injury Patients: A Focus on Bleeding Risk and Hospital-Stay Duration

Life
Background: Traumatic brain injury (TBI) in the elderly is a noteworthy pathology due to the exponential increase in population age, and the effects of antiplatelet and anticoagulation on patients’ outcomes are still a matter of dispute.

Anticoagulation Management [PDF]

Seminars in Interventional Radiology, 2010
To perform safe invasive procedures on patients on anticoagulation therapy, management of the patient's anticoagulation status is mandatory. For patients on anticoagulation therapy, a risk analysis of both the procedural risk of bleeding as well as the risk to the patient from discontinuing anticoagulation needs to be performed.

Restores Aβ Clearance by Overcoming PCSK9–LRP1 Dysregulation and TRIB3‐Mediated Autophagy Blockade in Alzheimer's Disease

Advanced Science, EarlyView.
PCSK9 upregulation in cerebrovascular endothelial cells and microglia destabilizes the Aβ transporter LRP1, while TRIB3‐associated autophagy blockade further limits intracellular Aβ degradation. A RAP‐modified tea‐polyphenol nanoparticle co‐delivers siPCSK9 and siTRIB3 to restore LRP1‐mediated Aβ efflux and autophagy‐dependent degradation, reducing Aβ ...

AI‐Designed TREM1‐Targeted LYTAC Nanoparticles Reprogram the Neuroimmune Microenvironment in Traumatic Brain Injury

Advanced Science, EarlyView.
AI‐enabled de novo design of a TREM1 binder, integrated into a BBB‐crossing and macrophage‐targeted nanoplatform, enables TREM1 degradation and attenuates neuroinflammation, thereby promoting neuroprotection and tissue repair after traumatic brain injury. ABSTRACT Secondary neuroinflammation drives progressive damage after traumatic brain injury (TBI),
