Ischemia-reperfusion injuries produce reactive oxygen species that promote the peroxide lipid oxidation process resulting in the production of an endogenic lipid peroxide, 4-hydroxy-trans-2-nonenal (4-HNE), a highly cytotoxic aldehyde that induces cell death. We synthesized a novel 4-HNE scavenger - a carnosine-hydrazide derivative, l-carnosine hydrazide (CNN) - and examined its neuroprotective effect in a model of transient ischemia. PC-12 cells were pre-incubated with various doses (0-50 mmol/L) of CNN for 30 min, followed by incubation with 4-HNE (250 μM). Read More

Non-graft-versus-host disease (non-GVHD) ocular complications are generally uncommon after hematopoietic cell transplantation (HCT), but can cause prolonged morbidity affecting activities of daily living and quality of life. Here we provide an expert review of non-GVHD ocular complications in a collaboration between transplant physicians and ophthalmologists through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation. Complications discussed in this review include cataracts, glaucoma, ocular infections, ocular involvement with malignancy, ischemic microvascular retinopathy, central retinal vein occlusion, retinal hemorrhage, retinal detachment and ocular toxicities associated with medications.

Ischemic stroke is an acute neurodegenerative disease that is extremely devastating to patients, their families and society. Stroke is inadequately treated even with endovascular procedures and reperfusion therapy. Using an extensive translational screening process, we have developed a pleiotropic cytoprotective agent with the potential to positively impact a large population of brain ischemia patients and revolutionize the process used for the development of new drugs to treat complex brain disorders.

Patients with coronary chronic total occlusion (CTO) if symptomatic for angina or with extensive inducible ischemia at provocative tests may be revascularized percutaneously or surgically. Percutaneous revascularization can be performed by antegrade or retrograde approach. In our case, in the presence of a long CTO of the left anterior descending coronary artery, the antegrade approach was chosen using an intravascular ultrasound (IVUS) catheter positioned in a secondary branch, to accurately identify the proximal lesion cap.

Myocardial revascularization in patients with stable ischemic heart disease aims at eliminating myocardial ischemia, in order to (i) relieve anginal symptoms; (ii) improve functional capacity; and, possibly, (iii) improve prognosis. Given that ischemic recurrences are relatively common in patients undergoing myocardial revascularization, an appropriate follow-up is needed as part of a secondary prevention program. Stress testing can be here useful to: (i) detect residual or recurrent ischemia/angina; (ii) define functional capacity in order to establish physical aerobic training individualized programs; (iii) stratify prognosis.

Hypoxic-ischemic brain injury is a complex network of factors, which is mainly characterized by a decrease in levels of oxygen concentration and blood flow, which lead to an inefficient supply of nutrients to the brain. Hypoxic-ischemic brain injury can be found in perinatal asphyxia and ischemic-stroke, which represent one of the main causes of mortality and morbidity in children and adults worldwide. Therefore, knowledge on underlying mechanisms triggering these insults may help establish neuroprotective treatments. Read More

We have previously reported that Cystatin C (CysC) is a pivotal mediator in the neuroprotection induced by hyperbaric oxygen (HBO) preconditioning; however, the underlying mechanism and how CysC changes after stroke are not clear. In the present study, we demonstrated that CysC expression was elevated as early as 3 h after reperfusion, and this was further enhanced by HBO preconditioning. Concurrently, LC3-II and Beclin-1, two positive-markers for autophagy induction, exhibited increases similar to CysC, while knockdown of CysC blocked these elevations. Read More

Purpose: We report 2 cases of young diabetic mothers with pre-eclampsia and no previously documented visual deficits prior to pregnancy who were found to have profound retinal circulation loss during the postpartum period.
Observations: Fluorescein angiogram in both cases documented profound ischemia of retinal and macular circulation with resulting severe vision loss, leading to legal blindness.
Conclusions And Importance: While Pre-eclampsia and Eclampsia are well known clinical entities with potentially grave effects on both the mother and child, there is little information about the possible combined effects of diabetes and Pre-eclampsia/Eclampsia on the retinal circulation. Read More

Sodium glucose cotransporter 2 inhibitors (SGLT2i) are the first antidiabetic compounds that effectively reduce heart failure hospitalization and cardiovascular death in type 2 diabetics. Being explicitly designed to inhibit SGLT2 in the kidney, SGLT2i have lately been investigated for their off-target cardiac actions. Here, we review the direct effects of SGLT2i Empagliflozin (Empa), Dapagliflozin (Dapa), and Canagliflozin (Cana) on various cardiac cell types and cardiac function, and how these may contribute to the cardiovascular benefits observed in large clinical trials.
