Isolated, remote heart metastasis of myxoid chondrosarcoma is extremely rare. We present an unusual case of isolated remote metastasis of extraosseus myxoid chondrosarcoma from the right ankle region to the right ventricle, its clinical course, and treatment in a 46-year-old woman. Although heart biopsy done before the surgery revealed myxoma, histopathologic diagnosis of the heart tumor was co...

Cells from anatomically remote organs of developing embryos do not normally encounter one another. If intercellular adhesive selectivity has a role in determining or maintaining the position of cells in organs, it should be exhibited between cells which are found in close proximity within a single organ. To test this hypothesis, a collecting cell-sheet assay for intercellular adhesive selectivi...

Pneumococcal affections of organs other than the lungs are often found complicating pneumonia. The occurrence of some of these ?complications like empyema, pericarditis, etc., can be easily explained by direct spread of the inflammatory process to the neighbouring structures. But the pathogenesis of the afflection of remote organs like the brain and meninges, joints, cardiac valves, etc., has a...

Primary peritoneal carcinoma (PPC) is a type of rare malignant epithelial tumor. Metastasis from PPC to breast has been rarely reported. PPC originates de novo from the peritoneal tissues rather than invasion or metastasis from adjacent or remote organs. PPCs have been implicated in many cases of carcinomas of unknown primary origin. It is similar to ovarian cancer (OvCa), because it shares the...

Osteocytes act as mechanosensors to control local bone volume. However, their roles in the homeostasis of remote organs are largely unknown. We show that ablation of osteocytes in mice (osteocyte-less [OL] mice) leads to severe lymphopenia, due to lack of lymphoid-supporting stroma in both the bone marrow and thymus, and complete loss of white adipose tissues. These effects were reversed when o...

There is currently no effective prophylactic regimen available to prevent contrast-induced AKI (CI-AKI), a frequent and life-threatening complication after cardiac catheterization. Therefore, novel treatment strategies are required to decrease CI-AKI incidence and to improve clinical outcomes in these patients. Remote ischemic preconditioning (rIPC), defined as transient brief episodes of ische...

Ischemic preconditioning is the phenomenon whereby brief periods of sublethal ischemia protect against a subsequent, more prolonged, ischemic insult. In remote ischemic preconditioning (RIPC), ischemia to one organ protects others organs at a distance. We created mouse models to ask if inhibition of the alpha-ketoglutarate (αKG)-dependent dioxygenase Egln1, which senses oxygen and regulates the...

In this issue of Brain and Behavior, Vasdekis et al. (2013) thoroughly review the theory behind remote ischemic preconditioning and the results to date of its application among patients with atherosclerotic narrowing of arteries supplying various organs including the brain. In these various trials and observations, clinicians and researchers artificially created ischemia to limbs to reduce isch...

Currently, there are no satisfactory interventions to protect the heart against the detrimental effects of ischemia-reperfusion injury. Although ischemic preconditioning (PC) is the most powerful form of intrinsic cardioprotection, its application in humans is limited to planned interventions, due to its short duration and technical requirements. However, many organs/tissues are capable of prod...
