Tenecteplase Thrombolysis for Stroke up to 24 Hours After Onset With Perfusion Imaging Selection: The CHABLIS-T II Randomized Clinical Trial.

Background: Whether it is effective and safe to extend the time window of intravenous thrombolysis up to 24 hours after the last known well is unknown. We aimed to determine the efficacy and safety of tenecteplase in Chinese patients with acute ischemic stroke due to large/medium vessel occlusion within an extended time window.

Methods: Patients with ischemic stroke presenting 4.

Drug-Loaded Microspheres on NIR-Responsive PLA/MXene Scaffolds: Controlled Release and Bone Tissue Regeneration.

The resection of bone tumors results in large bone defects with some residual tumor cells, and the treatment of this type of bone defect area often faces a dilemma, namely, the trade-off between bone repair and antitumor after the resection of bone tumors. In order to promote local bone repair, and at the same time inhibit tumor recurrence by continuous and controlled drug administration, we developed a multifunctional NIR-responsive scaffold, whose main components are polylactic acid and MXene, and loaded with PLGA/DOX microspheres, and we hope that the scaffold can take into account both antitumor and bone repair in the bidirectional modulation effect of NIR. The results showed that the scaffold with 1% MXene content had relatively good performance in photothermal therapy (PT) and other aspects, and it could be smoothly increased to 50 °C within 2 min under NIR illumination, and the drug release of microspheres was increased by 10% after illumination compared with that at body temperature.

Transgenic Cynodon dactylon overexpressing CdPIF4 alters plant development and cold stress tolerance.

Bermudagrass [Cynodon dactylon (L.) Pers.] is widely used for soil remediation, livestock forage, and as turfgrass for sports fields, parks, and gardens due to its resilience and adaptability.

[WWP1 plays a positive role in ameloblast differentiation and enamel formation in mice].

To investigate the role of WW domain containing E3 ubiquitin protein ligase 1 (WWP1) in enamel development of mice. Single-cell RNA sequencing data of incisor tissues of postnatal day 7 (P7) mice and mandibular first molar tooth germs of P3.5 mice were used to analyze the expression of WWP1 in dental epithelial cells.

Identification of human cranio-maxillofacial skeletal stem cells for mandibular development.

Compared with long bone that arises from the mesoderm, the major portion of the maxillofacial bones and the front bone of the skull are derived from cranial neural crest cells and undergo intramembranous ossification. Human skeletal stem cells have been identified in embryonic and fetal long bones. Here, we describe a single-cell atlas of the human embryonic mandible and identify a population of cranio-maxillofacial skeletal stem cells (CMSSCs).
