Innovative Strategies for Organ Preservation in Heart Transplantation: Uniform Cooling Preservation and Ex-situ Normothermic Perfusion
0 Views •
2025
Donor heart preservation is a major determinant of success in heart transplantation. Technological advances have led to optimizing the conditions of preservation, along with a more accurate assessment of the donor heart before transplantation. We herein describe two innovative technologies currently applied for cardiac preservation: uniform cooling preservation and normothermic ex-situ heart perfusion.

We demonstrate the use of the gene gun to introduce fluorescent dyes, such as DiI, into neurons in brain slices from rodents and non-human primates of different ages. In this particular case, we use adult mice (3-6 months old) and adult cynomologus monkeys (9-15 years old). This technique, originally described by the laboratory of Dr. Lichtman (Gan et al., 2000), is well suited for the study of dendritic branching and dendritic spine morphology and can be combined with traditional...

Preservation of laboratory samples, specimens, and reagents using extreme cold is routinely performed in biomedical research labs. This video will discuss some of the methods for keeping laboratory samples cold and will explain the correct cooling method to use for each experimental requirement. For example, cooling agents, such as ice and dry ice, are typically used when keeping samples cold during experiments. This video discusses the physical properties of the most commonly used cooling...

Pasteurization and Food Preservation

2026
Pasteurization is a widely employed thermal processing technique designed to enhance the safety and shelf life of perishable food and beverages. By subjecting products to specific high temperatures for controlled durations, this method effectively inactivates pathogenic microorganisms and spoilage enzymes without significantly compromising sensory qualities. The technique has been pivotal in food safety management, especially for consumables susceptible to microbial contamination such as milk,...

Principles of Food Preservation

2026
Food spoilage results from microbial growth, enzymatic activity, and environmental factors that gradually degrade the sensory, nutritional, and safety qualities of food. Preservation techniques aim to slow or halt these processes to extend shelf life and maintain product quality.A key concept in food microbiology is the microbial growth curve, which includes four phases: lag, exponential (log), stationary, and death. During the lag phase, bacteria adjust to their environment without significant...
FAQs
It targets several damaging processes simultaneously rather than focusing on cell survival alone. Reducing excitotoxicity limits injury associated with excessive neural stimulation, while controlling oxidative stress and neuroinflammation can lessen additional cellular damage. Addressing these mechanisms together is important because injury, disease, and laboratory stress can disrupt neurons through multiple interacting pathways.
Neurons require stable energy production to maintain their structure and activity. Mitochondrial dysfunction can undermine this energy balance, making cells more vulnerable after injury or during disease. Preservation strategies therefore consider mitochondrial health alongside other protective mechanisms. Supporting energy balance helps maintain neuronal viability and contributes to the retention of neural function in experimental and disease-related settings.
Keeping neurons alive does not by itself ensure that they remain functionally useful. Synaptic integrity, meaning preservation of the connections through which neurons communicate, is also an important outcome. Strategies that protect synapses can help maintain neural function while reducing cellular stress. This makes synaptic preservation relevant when studying whether an intervention retains meaningful neuronal activity rather than survival alone.
Laboratory studies apply preservation strategies to maintain viable brain tissue or neuronal cell cultures under experimental conditions. Researchers can then examine injury mechanisms, disease-related changes, or the effects of candidate neuroprotective treatments in material that remains sufficiently intact for study. Maintaining viability improves the opportunity to connect cellular changes with structural and functional outcomes.
It is particularly relevant when neuronal loss or dysfunction is central to the research question. Applications include studies of stroke, traumatic brain injury, aging, Alzheimer’s disease, and Parkinson’s disease. In these settings, preservation strategies help investigators examine how damage develops and whether limiting neuronal loss can support the retention of neural function.
Preserved neurons provide a more viable system in which potential neuroprotective treatments can be examined. Researchers can assess whether an intervention limits processes such as excitotoxicity, oxidative stress, mitochondrial dysfunction, or neuroinflammation while maintaining neuronal structure and synaptic integrity. This approach connects treatment effects with the biological mechanisms and functional outcomes relevant to neurodegenerative research.
