The purpose of this report is to present a safe, simple technique for procurement of the heart, liver, and kidneys from a single donor with no warm ischemic time. Twenty mongrel dogs were divided into 5 groups of 3 recipients and 1 donor each. Liver and kidney mobilization was performed when the core temperature of the liver reached 27 degrees C, a result of ice slush in the abdominal cavity. As the core temperature of the liver reached 20-22 degrees C, the aorta and inferior vena cava were clamped just above the diaphragm. After excision of the liver and kidneys, another team harvested the heart as it continued to beat. The heart and liver were transplanted orthotopically after simple preservation for 12 and 6 hours, respectively. The kidney was transplanted heterotopically after simple 12-hour preservation. The maximum survival time was 7 hours for heart transplantation and 16 days for liver transplantation. Kidney homogenate ATP levels decreased to 19% of baseline after preservation and were restored to 68% one hour after reperfusion. Our method is simple and safe for harvesting the heart, liver, an kidneys for transplantation and may offer a definite possibility for clinical application.

Hematologic complications are common in pregnancy and can significantly impact both maternal and fetal health. Recognizing and treating these complications can be challenging due to the limited evidence available to guide clinical consultants. Iron deficiency anemia is the most prevalent hematologic issue in pregnancy and often occurs due to increased maternal blood volume and the nutritional demands of the growing fetus.

This article provides radiologists with insights into stem cells' functions, sources, and potentially successful clinical treatments via intravascular injection in organs such as the liver, kidney, pancreas, musculoskeletal system, and for ischemic conditions affecting the brain, heart and limbs. Understanding stem cells' significance in interventional radiology and its limitations enables tailored interventions for diverse conditions, ensuring efficient medical care and optimal treatment selection.

Static cold storage of donor livers at 4 °C incompletely arrests metabolism, ultimately leading to decreases in ATP levels, oxidative stress, cell death, and organ failure. Hydrogen Sulfide (HS) is an endogenously produced gas, previously demonstrated to reduce oxidative stress, reduce ATP depletion, and protect from ischemia and reperfusion injury. HS is difficult to administer due to its rapid release curve, resulting in cellular death at high concentrations.

Liver fibrosis is a critical liver disease that can progress to more severe manifestations, such as cirrhosis, yet no effective targeted therapies are available. Here, we identify that ATF4, a master transcription factor in ER stress response, promotes liver fibrosis by facilitating a stress response-independent epigenetic program in hepatic stellate cells (HSCs). Unlike its canonical role in regulating UPR genes during ER stress, ATF4 activates epithelial-mesenchymal transition (EMT) gene transcription under fibrogenic conditions.
