This study addresses the demand for osteoinductive and mechanically strong scaffolds in bone tissue engineering (BTE) by developing a cell-free, interpenetrating network-based scaffold that combines extracellular vesicles (EVs) from pre-osteoblasts with a mineralized microenvironment to enhance bone regeneration. Utilizing MC3T3 pre-osteoblast cell line-derived EVs, the research identified an optimal concentration that significantly increases osteogenesis indicators such as alkaline phosphatase activity and calcium content, both in vitro and when integrated with a mineralized scaffold, suggesting a promising cell-free approach for enhancing bone repair in vivo.
This study aimed to explore the osteoinductive effects of natural hydroxyapatite (NHA) derived from pig bones on mouse bone mesenchymal stem cells (MSCs), using the MTT assay for proliferation and microarray technology for gene expression profiling. Results showed NHA influences the expression of 8992 differentially expressed genes, including 90 directly related to osteogenic differentiation through key signaling pathways like TGF-β and MAPK, suggesting NHA's potential in activating crucial genes and pathways for osteogenesis.
This study investigated the regulation of human bone marrow-derived mesenchymal stem cells (MSCs) by pulsed electromagnetic fields (PEMFs) and the intracrine conversion of dehydroepiandrosterone (DHEA) to dihydrotestosterone, focusing on their effects on cell viability and osteogenic differentiation. It was found that PEMFs increased cell viability for both MSCs and osteoblastic SaOS-2 cells, whereas DHEA decreased viability in a concentration-dependent manner but promoted osteo-induction of MSCs through conversion to dihydrotestosterone, suggesting a potential sequential therapeutic use in fracture healing.
How do HR functions, policies, and practices align with organizational strategies to support sustainable development goals? How can quantitative methods and the SABI database be utilized to measure the impact of HR policies and practices on sustainable development goals?
The poster underscores the necessity of a multidisciplinary approach in diagnosing and treating maxillary SCC, involving specialists in oral and maxillofacial surgery, radiology, pathology, oncology, and others. This collaborative effort is key to improving outcomes for patients with this challenging and potentially life-threatening condition.
The 2023 Ig Nobel Physics Prize is awarded to Bieito Fernández Castro et al for measuring the extent to which ocean-water mixing is affected by the sexual activity of anchovies. This is the article.
This group won an Ig Nobel prize in 2023 for their work on the Precision Health toilet, a “smart toilet” device capable of detecting diseases from excreta.
The 2023 Ig Nobel Medicine Prize was awarded to Christine Pham, Bobak Hedayati, Kiana Hashemi, Ella Csuka, Tiana Mamaghani, Margit Juhasz, Jamie Wikenheiser, and Natasha Mesinkovska, for using cadavers to explore whether there is an equal number of hairs in each of a person’s two nostrils. They documented their research in the study “The Quantification and Measurement of Nasal Hairs in a Cadaveric Population,” published in the International Journal of Dermatology.
This is a very interesting article. The engineers at Rice University in Houston, Texas, has made robotic grippers from dead spiders. And they’re being recognized for their creation of the mechanical gripping tools.
They were awarded an Ig Nobel Prize in 2023.
