Special Issue Information

Dear Colleagues,

Hypoxia in organs is a result of ischemia, due to either macrovascular or microvascular circulation collapse. It is a process that occurs either abruptly and acutely or gradually and chronically. Ischemia and hypoxia occur in brain stroke, traumatic brain injury, vasospasmus after subarachnoid hemorrhage, myocardial infarction, kidneys, and the gastrointestinal system; secondary hypoxia occurs during autoimmune inflammation or sepsis. This means that tissue hypoxia is a cardinal underlying process in almost every pathology.

However, hypoxia-induced pathologies lack up-to-date effective treatments. This is the well-known “translational block of protection” in the brain, heart, and other organs, which persists despite decades of research.

In our Special Issue (SI), we want to stimulate an “out-of-box” scientific interchange of studies that test conceptually novel molecular mechanisms and approaches for the detection and treatment of tissue hypoxia. We welcome the interdisciplinary crossing of scientific borders, e.g., by examining how a molecular pathway may be comparatively similar or different in a hypoxic brain, heart, kidney, or inflamed organ and why. Among others, we aim to collect papers with well-supported, “high-risk, high-innovative” ideas in the field of tissue hypoxia.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Heart transplantation remains the conventional treatment in end-stage heart failure, with static cold storage (SCS) being the standard technique used for donor preservation. Nevertheless, prolonged cold ischemic storage is associated with the increased risk of early graft dysfunction attributed to residual ischemia, reperfusion, and rewarming damage. In addition, the demand for the use of marginal grafts requires the development of new methods for organ preservation and repair. In this review, we focus on current knowledge and novel methods of donor preservation in heart transplantation. Hypothermic or normothermic machine perfusion may be a promising novel method of donor preservation based on the administration of cardioprotective agents. Machine perfusion seems to be comparable to cold cardioplegia regarding donor preservation and allows potential repair treatments to be employed and the assessment of graft function before implantation. It is also a promising platform for using marginal organs and increasing donor pool. New pharmacological cardiac repair treatments, as well as cardioprotective interventions have emerged and could allow for the optimization of this modality, making it more practical and cost-effective for the real world of transplantation. Recently, the use of triiodothyronine during normothermic perfusion has shown a favorable profile on cardiac function and microvascular dysfunction, likely by suppressing pro-apoptotic signaling and increasing the expression of cardioprotective molecules.
