Stimulator of interferon genes (STING): Key therapeutic targets in ischemia/reperfusion injury
Biomed Pharmacother. 2023 Sep 10;167:115458. doi: 10.1016/j.biopha.2023.115458. Online ahead of print.ABSTRACTThe Stimulator of Interferon Genes (STING) is predominantly expressed in immune cells, including macrophages, natural killer cells, dendritic cells, and T cells, functioning as a pattern recognition receptor. STING activation upon detecting cytosolic DNA released from damaged cells initiates downstream pathways, leading to the production of inflammatory cytokines such as IFNs, IL-6, and TNF-α. Dysregulated STING activation has been implicated in inflammatory and metabolic diseases. Ischemia/reperfusion injury (I/R...

Can ‘toxic’ bilirubin treat a variety of illnesses?
Generations of medical and biology students have been instilled with a dim view of bilirubin. Spawned when the body trashes old red blood cells, the molecule is harmful refuse and a sign of illness. High blood levels cause jaundice, which turns the eyes and skin yellow and can signal liver trouble. Newborns can’t process the compound, and although high levels normally subside, a persistent surplus can cause brain damage. Yet later this year up to 40 healthy Australian volunteers may begin receiving infusions of the supposedly good-for-nothing molecule. They will be participating in a phase 1 safety trial, sponsored ...

When does life end? New organ donation strategy fuels debate
On a chilly holiday Monday in January 2020, a medical milestone passed largely unnoticed. In a New York City operating room, surgeons gently removed the heart from a 43-year-old man who had died and shuttled it steps away to a patient in desperate need of a new one. More than 3500 people in the United States receive a new heart each year. But this case was different—the first of its kind in the country. “It took us 6 months to prepare,” says Nader Moazami, surgical head of heart transplantation at New York University (NYU) Langone Health, where the operation took place. The run-up included oversight from an ethi...

Elective Cardiopulmonary Bypass for Lung Transplantation: Is It Safer Than We Think
The use of cardiopulmonary bypass (CPB) during lung transplantation is controversial. CPB can offer improved visualization, better control of central vasculature, and possibly faster operations. Opponents argue the use of CPB results in higher transfusion requirements, increased rates of primary graft dysfunction (PGD), and more complications such as stroke, acute kidney injury (AKI) and renal failure requiring hemodialysis. In the fall of 2020 our program transitioned to performing all lung transplants on CPB.

Chronic Rejection and Atherosclerosis in Post-Transplant Cardiovascular Mortality: Two Sides of the Same Coin
Cardiovascular disease (CVD) as defined by the American Heart Association includes ischaemic heart disease, stroke, heart failure and thromboembolism [1]. Solid organ transplantation is associated with an increased risk of CVD morbidity and mortality [2], a relationship which was first observed in the context of kidney transplantation by Foley in 1998 [3]. This manifests clinically as an increased rate of major adverse cardiovascular events (MACE), defined as the composite of cardiac death, non-fatal myocardial infarction, non-fatal stroke, unstable angina and heart failure [4,5].

Unusual Symptoms of Coronavirus: What We Know So Far
While most people are familiar with the hallmark symptoms of COVID-19 by now—cough, fever, muscle aches, headaches and difficulty breathing—a new crop of medical conditions are emerging from the more than 4 million confirmed cases of the disease around the world. These include skin rashes, diarrhea, kidney abnormalities and potentially life-threatening blood clots. It’s not unusual for viruses to directly infect and affect different tissues and organs in the body, but it is a bit unusual for a primarily respiratory virus like SARS-CoV-2, which is responsible for COVID-19, to have such a wide-ranging reach...

Failure to rescue contributes to center-level differences in mortality after lung transplantation
ConclusionsDifferences in rates of Failure to Rescue contribute significantly to per-center variability in mortality following LTx. FTR can serve as a quality metric to identify opportunities for improvement in management of perioperative adverse events.

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Exercise as a Prescription for Patients with Various Diseases
Publication date: Available online 18 April 2019Source: Journal of Sport and Health ScienceAuthor(s): Xin Luan, Xiangyang Tian, Haixin Zhang, Rui Huang, Na Li, Peijie Chen, Ru WangAbstractA growing understanding of the benefits of exercise over the past few decades has prompted researchers to take an interest in the possibilities of exercise therapy. Because each sport has its own set of characteristics and physiological complications that tend to appear during exercise training, the effects and underlying mechanisms of exercise remain unclear. Thus, the first step in probing exercise effects on different diseases is the s...

Effects of Normothermic Machine Perfusion Conditions on Mesenchymal Stromal Cells
In this study the effect of NMP perfusion fluid on survival, metabolism and function of thawed cryopreserved human (h)MSC and porcine (p)MSC in suspension conditions was studied. Suspension conditions reduced the viability of pMSC by 40% in both perfusion fluid and culture medium. Viability of hMSC was reduced by suspension conditions by 15% in perfusion fluid, whilst no differences were found in survival in culture medium. Under adherent conditions, survival of the cells was not affected by perfusion fluid. The perfusion fluid did not affect survival of fresh MSC in suspension compared to the control culture medium. The f...
