Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for inducing severe therapeutic hypothermia in non-hibernating mammals face complications, and prolonged cold storage of organs and tissues leads to oxidative stress and cellular damage, necessitating improved compositions and methods for preserving cells, tissues, and organs at low temperatures.
Innovation Solution
A composition comprising a mitochondrial uncoupling agent, protease inhibitor, and reducing agent is used to protect cells, tissues, or organs from low temperature environments, targeting mitochondrial and protein degradation machineries to enhance survival and recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If severe therapeutic hypothermia is induced in non-hibernating mammals, then brain protection is improved, but complications and irreversible damage increase
Solution Approach 1:
The patent applies preliminary action by pre-treating cells, tissues, or organs with a composition containing a mitochondrial uncoupling agent, protease inhibitor, and reducing agent before exposing them to low temperature environments. This pre-treatment prepares the biological material to withstand cold stress by establishing protective mechanisms in advance, thereby enabling severe therapeutic hypothermia to be performed with reduced complications and irreversible damage.
2Duration of action of stationary object
If prolonged cold storage is used for organ preservation, then organ viability is improved, but oxidative stress and cellular damage increase
Solution Approach 1:
The patent uses an intermediary composition as a mediator between the cold storage environment and the organ tissue. This composition, containing a mitochondrial uncoupling agent, protease inhibitor, and reducing agent, acts as a protective intermediary that mitigates the harmful effects of prolonged cold storage. The reducing agent specifically counteracts oxidative stress while the protease inhibitor prevents cellular damage, thereby extending organ viability during storage.
3Object-affected harmful factors
If cold storage solution is enriched with antioxidant components, then oxidative injury is reduced, but microtubule disruption and degradation still occur
Solution Approach 1:
The patent employs a composite protective composition that combines multiple functional components: a mitochondrial uncoupling agent to address oxidative stress, a protease inhibitor to prevent protein degradation, and a reducing agent to maintain cellular redox balance. This composite formulation provides comprehensive protection against cold storage damage, simultaneously preventing both oxidative injury and microtubule disruption, thereby maintaining microtubule stability during prolonged cold storage.
