Study of some genetic predisposition in pulmonary embolism

Egyptian Journal of Chest Disease and Tuberculosis, 2014
Background: There is increasing recognition of genetic deficiencies underlying pulmonary embolism in some individuals, particularly those with early onset of disease, unusual sites of venous thrombosis and recurrent disease.

Asymmetric Evolution of Antennal Cell Types Underlies a Derived Ammonia‐Sensing Logic for Ecological Adaptation in Bactrocera dorsalis

Advanced Science, EarlyView.
Comparative antennal single‐nucleus transcriptomics reveals cell‐type‐dependent transcriptomic divergence in Bactrocera dorsalis, with similar structural cells but divergent sensory neurons. This neuronal diversification is associated with a distinct ammonia‐sensing pathway, linking female attraction to bird‐dropping‐associated cues with nutritional ...

Bone Marrow Macrophage STING Signaling is a Direct Nexus Linking Marrow Adipose Expansion to NAD+ Depletion and Osteogenic Decline in Skeletal Aging

Advanced Science, EarlyView.
This study reveals that during skeletal aging, bone marrow adipocyte‐derived sDPP4 primes STING signaling in macrophages. In combination with mitochondrial DNA, this signaling activates CD38 and depletes local NAD+/NMN, thereby impairing osteogenesis.

Versatile Microgel Platform for Intervertebral Disc Degeneration Therapy: Targeting Pericyte‐Mediated Fibrosis and Protecting Nucleus Pulposus Cells

Advanced Science, EarlyView.
The engineered MMS@TRP microgel enables targeted, acid‐responsive delivery of a miR‐21 inhibitor to pericytes. It effectively suppresses disc fibrosis by inhibiting TGF‐β signaling while protecting nucleus pulposus cells via sustained, antioxidant tannic acid release.

Rastreamento familiar do fator V de Leiden: a importância da detecção de portadores heterozigotos Familiar tracking of factor V Leiden: the importance of detection in heterozygous carriers

Revista Brasileira de Hematologia e Hemoterapia, 2005
O fator de Leiden é uma mutação genética que predispõe seus portadores ao tromboembolismo venoso. O objetivo do estudo foi investigar a distribuição dos alelos em 21 membros da família de três pacientes portadores de trombose com a presença da mutação do

Thrombin generation in a woman with heterozygous factor V Leiden and combined oral contraceptives: A case report

Research and Practice in Thrombosis and Haemostasis, 2020
Combined oral contraceptives and factor V Leiden mutation are multiplicative risk factors for venous thromboembolism. However, it remains unknown whether this multiplicative effect is reflected in thrombin generation assays.

Thioredoxin‐2 Alleviates Osteoporosis by Restraining FOXO3a Nuclear Translocation

Advanced Science, EarlyView.
Endothelial TRX2 preserves bone homeostasis by retaining FOXO3a at mitochondria and limiting TRAIL production. Loss of TRX2 or oxidative stress releases FOXO3a for nuclear translocation, increasing endothelial TRAIL secretion and driving osteoclast formation and bone loss.

Acinar‐Derived Organoids Reveal Stage‐Specific Control of Acinar Plasticity

Advanced Science, EarlyView.
An acinar‐derived organoid system maintains adult pancreatic acinar identity ex vivo, converts it along an ordered acinar‐to‐ductal‐like trajectory, and then partially restores it. Each transition carries its own signal requirement, with EGF/EGFR initiating conversion and a staged glucocorticoid–IGF1R switch driving redifferentiation.
