Article Synopsis
- Hydroxyapatite (HAp) coatings are used on bone implants to enhance biocompatibility and promote bone growth, but they can still lead to infections.
- This study explored the use of high-velocity suspension flame spraying (HVSFS) to create thin HAp coatings and tested the effects of varying gas parameters and copper (Cu) additions on their properties and effectiveness.
- Results indicated that using medium gas parameters and adding 1 wt.% Cu provided a good balance between antibacterial properties and biocompatibility, effectively reducing bacterial counts while limiting cytotoxic effects.
Article Synopsis
- Prosthesis loosening is a common implant failure caused by insufficient bonding between the implant and surrounding bone, often compounded by bacterial infection and biofilm.
- Using bioconductive and biodegradable calcium phosphate (CaP) coatings with incorporated antibacterial agents can enhance both bone integration and combat bacterial growth.
- This study focuses on creating Cu-doped CaP coatings with better porosity and antibacterial properties, showing good biocompatibility and effective antimicrobial action against various bacterial strains.
Pollinator diversity of the food-deceptive orchids in southern Italy.
Plant Biol (Stuttg)
December 2024
The orchid family is renowned for its enormous diversity in pollination biology. Many orchid species use deception to attract pollinators, and the main strategy in terrestrial orchids is food deception. Food-deceptive orchids usually show a low number of pollinator visitations, making field observations of pollinators difficult.

- * By overexpressing FoxO3a in TamR-BCCs, researchers found it reduced their oxygen consumption and glycolytic rates, lowering their metabolic activity and promoting glucose accumulation.
- * Proteomic analysis indicated that FoxO3a decreased levels of important enzymes related to carbohydrate metabolism, suggesting that drugs that activate FoxO3a could be beneficial for treating patients resistant to antiestrogen therapy.
Orchidaceae, one of the most numerous families in the world's flora, have evolved various pollination strategies to favour cross-pollination, such as deceptive pollination and pollinarium reconfiguration. Among the terrestrial orchids of the Mediterranean, only species belonging to the genus show a strategy defined as shelter imitation. The floral elements form a tubular structure that insects use during their resting phases.
