ASL 4D MRA Intracranial Vessel Segmentation With Deep Learning U‐Nets

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2384-2396, April 2026.
ABSTRACT Purpose To propose a spatio‐temporal U‐Net based network (4DST) that exploits both spatial and dynamic information while avoiding memory‐intensive 4D convolutional layers for ASL‐based non‐contrast enhanced 4‐dimensional MR angiography (4D MRA) vessel segmentation.

Teleost‐specific ictacalcins exhibit similar structural organization, cation‐dependent activation, and transcriptional regulation as human S100 proteins

The FEBS Journal, Volume 293, Issue 7, Page 2042-2066, April 2026.
Calcium‐binding S100 proteins are important mediators of inflammation in humans. Distant members of this family have been recently discovered in teleost fish but their resemblance to human proteins has not been explored yet. This study demonstrates that zebrafish‐specific S100i1 and S100i2 (ictacalcins) possess identical structural organization and ...

Measuring Direct Oral Anticoagulant (DOAC) Levels: Applications, Limitations, and Future Directions

International Journal of Laboratory Hematology, Volume 48, Issue 2, Page 250-258, April 2026.
ABSTRACT Introduction There are important challenges with the measurement and interpretation of direct oral anticoagulant (DOAC) anticoagulant effect including a lack of therapeutic ranges, inaccuracy of routinely available coagulation assays, lack of established thresholds for clinically significant effect, and uncertainty about how to apply the ...

A Retrospective Study of Adult and Pediatric D‐Dimer Tests to Identify Opportunities for Improved Utilization

International Journal of Laboratory Hematology, Volume 48, Issue 2, Page 392-401, April 2026.
ABSTRACT Introduction D‐dimers are produced by lysis of cross‐linked fibrin. In children, D‐dimer testing is used to evaluate disseminated intravascular coagulation (DIC) and some inflammatory states, but its use is not validated for screening or ruling out suspected venous thromboembolic events (VTE).

Targeted Therapies in Infantile Hemangiomas and Vascular Malformations: From β‐Blockers to PI3K/AKT/mTOR Inhibitors

Journal of Cellular and Molecular Medicine, Volume 30, Issue 7, April 2026.
ABSTRACT Vascular tumours and malformations encompass infantile hemangiomas (IHs) and genetically driven vascular malformations with distinct natural histories and therapeutic vulnerabilities. The discovery that the non‐selective beta‐blocker propranolol induces rapid regression of proliferating IHs established the first widely adopted systemic ...
