Summary: The ketogenic diet is now commonly used for weight loss by restricting carbohydrate intake to promote fat burning. Breath and blood ketone levels can be measured to gauge the level of ketosis and adjust the diet accordingly. Breath acetone sensors are becoming more common due to less invasiveness and convenience, with new technologies being researched to capitalize on the popularity of the diet.

Summary: Nanoparticles are commonly used as delivery vehicles for drugs, but their diffusion often leads to inconsistent drug release. In this study, brain-derived neurotrophic factor (BDNF) is attached to photoactive titanium dioxide nanoparticles and loaded into a nanofibrous self-assembling peptide (SAP) hydrogel. By manipulating UV exposure conditions, the researchers were able to achieve a more constant and flattened drug release profile. The adsorption of the growth factor onto the hydrogel nanofibers and the interaction between the released growth factor and the hydrogel were found to affect the drug release. This study demonstrates the potential for precise control of drug release by manipulating the amount of bound growth factor on the nanoparticles and provides insights into the diffusion and release behavior of nanoparticles in hydrogels.
