3D bioprinted scaffolds enhance bone healing through improved vascularization

Bone is a highly vascularized tissue, and the link between angiogenesis -blood vessel formation- and bone healing has long been discussed by the scientific community, with several studies describing the impairment of bone healing because of lack of or diminished angiogenesis. Traditional approaches like grafting often result in complications due to an inadequate vascular supply to implants, leading to poor integration and necrotic tissue.

Study reveals brain’s role in starting meals through GABA, dopamine

When you are feeling hungry, the brain takes the necessary steps toward consuming a meal. Many of these steps are not well known, but a new study published in the journal Metabolism by researchers at Baylor College of Medicine and the University of Texas Health Science Center at Houston reveals brain circuits and chemical messengers that contribute to the regulation of meal initiation and food intake. The findings have implications for the development of improved therapies to manage obesity, a worldwide epidemic.
