Patent number: 11673289Abstract: Methods and systems are described for fabricating a component using 3D printing. A 3D printed piece is created including a body of the component, a support structure, and a first sacrificial interface region coupling the body of the component to the support structure. The body of the component is formed of a first metal or ceramic material and the first sacrificial interface region is formed at least partially of a second metal or ceramic material. The body of the component is then separated from the support structure by applying a chemical or electrochemical dissolution process to the 3D printed piece. Because the second metal or ceramic material is less resistant to the dissolution process than the first metal or ceramic material, the first sacrificial interface region at least partially dissolves, thereby separating the body of the metal component from the support structure, without dissolving the body of the component.Type: GrantFiled: February 16, 2017Date of Patent: June 13, 2023Assignees: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITY, THE PENN STATE RESEARCH FOUNDATIONInventors: Owen Hildreth, Abdalla Nassar, Timothy W.

Patent number: 11666640Abstract: Neonatal seizure is different from adult seizure, and many anti epileptic drugs that are effective in adults often fail to treat neonatal seizure. Gluconic acid, a natural organic acid enriched in fruits and honey, and the glucose oxidase enzyme, is shown herein to potently inhibit neonatal epilepsy both in vitro and in vivo. Sodium gluconate is shown to inhibit epileptiform burst activity in cell cultures and protect neurons from kainic acid-induced cell death. Sodium gluconate also inhibited epileptiform burst activity in brain slices in a manner that was much more potent in neonatal animals than in older animals. Consistently, in vivo EEC recordings also revealed that sodium gluconate inhibited the epileptic seizure activity in a manner that was much more potent in neonates than in adult animals. Mechanistically, sodium gluconate inhibits voltage-dependent CLC-3 C1? channels both in neuronal cultures and in hippocampal slices.Type: GrantFiled: January 3, 2019Date of Patent: June 6, 2023Assignee: PENN STATE RESEARCH FOUNDATIONInventors: Gong Chen, Zheng Wu
