  • Publication number: 20230372589
    Abstract: Disclosed herein implantable material and methods for treatment of growth plate injuries and other purposes. These materials can be particularly useful for treating children whose growth plates are active, and can help encourage proper healing and inhibit unwanted bone formations. Exemplary compositions can comprise poly (ethylene glycol) (“PEG”), gelatin (“GEL”), and heparin (“HEP”). The PEG, GEL, and HEP components can be present in various forms of these materials, such as methacrylated forms, etc. The implanted materials can be anti-osteogenic and/or ant-mineralization, and can help prevent unwanted bone growth in the implanted area, such as boney tethers, which can inhibit desirable growth plate healing and overall bone growth.

  • Publication number: 20230357430
    Abstract: The present subject matter relates to the use of one or more inhibitors to treat a disease, e.g., cancer, in a subject. It is based, at least in part, on the discovery that protein kinase B (AKT) and ring finger protein 167 (RNF167)-mediated CASTOR1 degradation activates the mammalian target of rapamycin complex 1 (mTORC1) independent of arginine and promotes cancer progression. Accordingly, the presently disclosed subject matter provides for compositions, methods, and kits for treating a subject using an RNF167 inhibitor, an inhibitor that reduces phosphorylation of CASTOR1 at S14, ubiquitination and/or degradation of CASTOR1, or a combination thereof.

  • Publication number: 20230347111
    Abstract: Disclosed catheter insertion systems enable the user to identify the location of the needle based on the electrical properties of subcutaneous tissue relative the electrical properties of other fluids such as blood or air. Disclosed systems can include one or more of the following features: 1) the catheter assembly is modular (e.g., the catheter can be connected and disconnected from the detection unit at will); 2) the detection unit employs an electrical circuit that allows for the discernment between subcutaneous tissue and blood; 3) the system assists the end user with catheter advancement. Some embodiments can be used to insert catheters into a spaces where the needle passes first through subcutaneous fat and muscle before entering fluid or air.

  • Publication number: 20230338627
    Abstract: The invention relates to self-cleaning porous structures, e.g., layers or coatings, fabricated within, applied to, or deposited on a blood contacting surface of a medical device, to prevent activation and aggregation of platelets thereon. In certain embodiments, the layer or coating is composed of multi-layered fibers. The porous structure is applied to or deposited such as to form a permeable wall on the blood contacting surface. The blood travels into the wall and subsequently back out (reversing back into the lumen) during a cardiac cycle. Reversal flow is controlled during the diastole phase such that the backward flow repels the platelets and prevents their activation and aggregation and therefore, minimizes thrombus formation.
