Bioactive Zn ingredients endow Ti-Zn composites with exceptional mechanical and osteogenic properties as biomedical implants.

Titanium-based (Ti-) alloys are promising materials as bioimplants with superior mechanical properties and excellent biocompatibility. However, their bioinertia and high elastic moduli are not comparable to natural bone tissue; thus, novel Ti alloys with good biomechanical adaptation and high bioactivity are desired. Zinc (Zn) is recognized for ideal biodegradability and its biological effects can be considered to endow pure Ti with rewarding bio functions.

Intranasal Delivery of Brain-Derived Neurotrophic Factor (BDNF)-Loaded Small Extracellular Vesicles for Treating Acute Spinal Cord Injury in Rats and Monkeys.

Besides surgical decompression, neuroprotection and neuroinflammation reduction are critical for acute spinal cord injury (SCI). In this study, we prepared small extracellular vesicles (sEVs) from immortalised mesenchymal stem cells overexpressing brain-derived neurotrophic factor (BDNF) and evaluated whether intranasal administration of BDNF-sEVs is a therapeutic option for acute SCI. In cultured neurons, BDNF loading enhanced neurite outgrowth promoted by sEVs.

Apolipoprotein B100 acts as a tumor suppressor in ovarian cancer via lipid/ER stress axis-induced blockade of autophagy.

Region-specific H3K9me3 gain in aged somatic tissues in Caenorhabditis elegans.

Epigenetic alterations occur as organisms age, and lead to chromatin deterioration, loss of transcriptional silencing and genomic instability. Dysregulation of the epigenome has been associated with increased susceptibility to age-related disorders. In this study, we aimed to characterize the age-dependent changes of the epigenome and, in turn, to understand epigenetic processes that drive aging phenotypes.

New Enantiomers of a Nor-Bisabolane Derivative and Two New Phthalides Produced by the Marine-Derived Fungus LD-201810.
