In the 1930s, a series of bubonic plague outbreaks among humans cropped up in several villages at the border of Angola and Namibia. These outbreaks provoked deep concern, laying bare social and political tensions amongst neighboring imperial powers and Indigenous people within the region. Despite the appearance of this disease in what was then considered a recondite place, its spread sparked debate in transnational forums, such as the League of Nations and the Office International d'Hygiène Publique.

Background: MET gene exon 14 skipping was identified as a potential driver mutation that occurs in approximately 3%-4% of patients with nonsmall cell lung cancer (NSCLC), typically in the absence of other driver mutations. Capmatinib and tepotinib were the first MET- tyrosine kinase inhibitors (MET-TKIs) approved by the FDA and PMDA, specifically for patients with metastatic NSCLC. Several studies have reported acquired resistance after MET-TKI treatment for MET mutation-positive NSCLC.

Department of Operative Dentistry and Endodontics, Shanghai Stomatological Hospital & School of Stomatology, Fudan University & Shanghai Key Laboratory of Craniomaxillofacial Development and Diseases, Fudan University, Shanghai201602, China.

Tooth development is a complex biomineralization process formed through the interaction between epithelial tissue and mesenchymal tissue. The Ca transport channel is the intrinsic regulatory mechanism of this process, which regulates the concentration of Ca inside and outside the cell in time and space, thereby affecting the biological functions of various cells and the growth of extracellular hydroxyapatite. This article reviews the researches on the effects of Ca transport in tooth biomineralization and corresponding cell development in recent years, with the aim of providing ideas and basis for the prevention of tooth developmental defects, assisting in early clinical diagnosis, and improving treatment methods.

Tooth development is a complex process of the orderly interaction between epithelium originating from the ectoderm and mesenchyme derived from cranial neural crest cells, which not only depends on cell genes regulatory network but also involves crosstalk between cells and their surrounding environment. Even within the same type of cellular populations, obvious heterogeneity may be observed. Single-cell RNA sequencing is a novel technology aimed at sequencing the transcriptome of individual cell.

Single-cell and spatial multi-omics technologies enable the simultaneous analysis of thousands of cells in various states, revealing their transcriptional profiles, chromatin accessibility, and spatial positioning. Recent advances in single-cell multi-omics have led to significant discoveries regarding the definition, function, evolution, and interaction of various cell subtypes during tooth development. We summarize key findings from recent single-cell multi-omics studies on tooth development, highlighting their contributions to the field and discussing future perspectives in dental developmental genomics research.

The post-and-core is a widely accepted method to restore endodontically treated teeth with compromised tooth structure. Currently, cast metal post-and-core systems and prefabricated fiber posts combined with composite resin cores are the most frequently options in dental clinical practice, but both also come with advantages and limitations. The development of computer-aided design/computer-aided manufacturing (CAD/CAM) custom fiber post-and-core represents one of the significant trends in the advancement of dentistry.

Pedicle ossification is a rare but significant complication following mandibular reconstruction using a fibular free flap (FFF), a technique widely employed in maxillofacial surgery due to its reliable vascularized bone supply and low donor site morbidity. The FFF supports dental implantation and prosthetic rehabilitation, with its vascularized periosteum enhancing osteogenic potential. Despite these advantages, unexpected ossification of the flap's vascular pedicle may occur, potentially mimicking tumor recurrence and causing diagnostic uncertainty.

In light of the lack of reliable molecular markers for odontogenic myxoma (OM), the detection of copy number variation (CNV) may present a more objective method for assessing ambiguous cases. In this study, we employed multiregional microdissection sequencing to integrate morphological features with genomic profiling. This allowed us to reveal the CNV profiles of OM and compare them with dental papilla (DP), dental follicle (DF), and odontogenic fibroma (OF) tissues.

Introduction: As the delivery of continuing medical education moves towards digital modes, determining how to embed and capitalise on the skills of specialised educators in digital modalities is critical. Drawing on social theories of adult learning and behaviour change, this study trialled multiple delivery modes of education about reproductive genetic 'carrier screening' with varying levels of specialised educator (genetic counsellors) input to examine clinical effectiveness, and health care practitioners and educator preferences.

Methods: A subset of health care practitioners (n = 209) interested in offering carrier screening through a large study were randomly allocated to receive education via face-to-face, a pre-recorded video or an online module, with active or passive educator input.

Multi-omics approach reveals TGF-β signaling-driven senescence in periodontium stem cells.

State Key Laboratory of Oral Diseases, National Center for Stomatology, National Clinical Research Center for Oral Diseases, Department of Head and Neck Oncology, West China Hospital of Stomatology, Sichuan University, Chengdu 610041, China. Electronic address:

Introduction: The periodontal ligament (PDL), a dynamic connective tissue that anchors teeth to the alveolar bone, enables tooth retention and facilitates continuous turnover. The integrity of the periodontium is maintained by periodontal ligament stem cells (PDLSCs), whose dysfunction and senescence with age can disrupt tissue homeostasis, hinder injury repair, and lead to tooth loss, ultimately impacting overall health. Transforming growth factor-β1 (TGF-β1) is known for its regenerative properties and as a functional paracrine factor in stem cell therapy, but its precise role in modulating PDLSC activity remains controversial and poorly understood.
