Cardiovascular diseases (atherosclerosis, stroke, myocardiac infarction etc.) are the major systemic diseases of elder peoples in the world. This is possibly due to increased levels of oxidized low-density lipoproteins (oxLDLs) such as 7-ketocholesterol (7-KC) and lysophosphatidylcholine (LPC) that damage vascular endothelial cells, induce inflammatory responses, to elevate the risk of cardiovascular diseases, Alzheimer's disease, and age-related macular degeneration. However the toxic effects of 7-KC on endothelial cells are not known...

The effect of sevoflurane postconditioning (sevo-postC) cardioprotection is compromised in diabetes which is associated with increased oxidative stress. We hypothesized that antioxidant N-Acetylcysteine may enhance or restore sevo-postC cardioprotection in diabetes. Control or streptozotocin-induced Type 1 diabetic rats were either untreated or treated with N-Acetylcysteine for four weeks starting at five weeks after streptozotocin injection and were subjected to myocardial ischemia-reperfusion injury (IRI), in the absence or presence of sevo-postC...

As a population ages, an increase in the number of patients with cardiac complications who undergo non-cardiac surgeries is observed. The perioperative mortality for noncardiac surgery is approximately 1-5%; approximately 20-35% of these cases are due to cardiovascular complications. Among them, perioperative myocardiac infarction/ischemia is a factor that leads to poor prognosis, and the ACC/AHA guidelines emphasize this aspect. An important task of the anesthesiologist is to accurately assess risks in patients undergoing noncardiac surgeries and avoid adverse cardiovascular events...

Midkine (MK) and pleiotrophin (PTN) belong to the subfamily of heparin binding growth factors. They have ca. 50% structural homology, with similar C- and N-domains as well as comparable binding affinity to heparin, glycoproteins and proteoglycans. Both MK and PTN have diverse functions, such as mitogenicity, inflammation, angiogenesis, oncogenesis and stem cell self-renewal. The high expression of MK and PTN in many kinds of cancers makes them excellent as cancer biomarkers and targets for anticancer drug development...

We investigated the regeneration of cardiac lymphatic vessels and capillaries in the infarcted myocardiac zones after acute myocardial infarction in rats. The anterior descending artery of the heart was ligated for infarction and both immunohistochemistry and immunofluorescence were used to detect pathological changes of lymphatic vessels in infarcted zone (IZ), infarcted margin zone (MZ) and remote margin zone (RMZ) on days 7, 14, 21, and 28 after surgery. Dynamic variation of lymphatic vessels existed in IZ, MZ and RMZ at different stages after surgery...

Early reperfusion after myocardial ischemia that is essential for tissue salvage also causes myocardial and vascular injury. Cardioprotection during reperfusion therapy is an essential aspect of treating myocardial infarction. Angiopoietin-1 is an endothelial-specific angiogenic factor. The potential effects of angiopoietin-1 on cardiomyocytes and vascular cells undergoing reperfusion have not been investigated. We propose a protective mechanism whereby angiopoietin-1 increases the integrity of the endothelial lining and exerts a direct survival effect on cardiomyocytes under myocardial ischemia followed by reperfusion...

Antithymocyte globulin (ATG) has been used in severe aplastic anemia (SAA) as part of the conditioning regimen. Among the many kinds of ATG preparations, thymoglobulin had been found to be more effective for preventing graft-versus-host disease (GVHD) and the rejection of organ transplants. After the promising results of our preliminary study, we conducted a phase II prospective multicenter clinical trial using a fludarabine (Flu), cyclophosphamide (Cy), and thymoglobulin conditioning regimen to allow good engraftment in patients who underwent unrelated transplantation for SAA...

Systemic air embolism, a very rare clinical condition, has many causes. We report a case of multiple air embolisms following laryngopharyngoesophagectomy salvage surgery for hypopharyngeal residual cancer after concurrent chemoradiotherapy. Cervical infection arose from a fistula caused by postoperative suture failure in which the 56-year-old man suddenly lost consciousness and went into shock. A few days post operation, an air embolism happened and caused in the brain, pulmonary, myocardiac and cerebral infarction...

Hypoxia-inducible factor-1alpha/beta (HIF-1alpha/beta) is a heterodimeric transcriptional activator that mediates gene expression in response to hypoxia. HIF-1alpha has been noted as an effective therapeutic target for ischemic diseases such as myocardiac infarction, stroke and cancer. By using a yeast two-hybrid system and a random peptide library, we found a 16-mer peptide named F29 that directly interacts with the bHLH-PAS domain of HIF-1alpha. We found that F29 facilitates the interaction of the HIF-1alpha/beta heterodimer with its target DNA sequence, hypoxia-responsive element (HRE)...

Pseudallescheria boydii is a saprophytic fungus frequently isolated from agricultural soil and polluted water. Disseminated and invasive infections with this organism are seen primarily in the immunocompromised host. We present an unusual case of invasive P. boydii infection in an immunocompetent patient admitted to our hospital with clinical, laboratory and ECG findings of a possible acute myocardiac infarction. Six hours after admission without treatment with thrombolytic agents she presented with a right hemiparesis and loss of consciousness; a CT scan showed a cerebral hemorrhage...
