Anti-phospholipase A2 receptor antibody as a prognostic marker in patients with primary membranous nephropathy.

Background: Phospholipase A2 receptor (PLA2R) has been identified as a major autoantigen in primary membranous nephropathy (MN). We evaluated the association between anti-PLA2R antibodies and clinical outcome in Korean patients with primary MN.

Methods: A total of 66 patients with biopsy-proven MN were included.

Tachycardia-Induced Right Heart Failure and Severe Tricuspid Regurgitation That Improved with Medication.

Secondary tricuspid regurgitation (TR) primarily develops due to left heart failure or primary pulmonary diseases. Tricuspid annular dilation, which is commonly caused by right ventricular volume and pressure overload followed by right ventricle dilation, is believed to be the main mechanism underlying secondary TR. It is reported that once the tricuspid annulus is dilated, its size cannot spontaneously return to normal, and it may continue to dilate.

Left Ventricular Strain as Predictor of Chronic Aortic Regurgitation.

Background: It is not well known about the implication of left ventricular (LV) strain as a predictor for mortality in patients with chronic aortic regurgitation (AR). The purpose of this study was to investigate whether global longitudinal strain measured by two-dimensional speckle-tracking echocardiography could predict long-term outcome in patients with chronic AR.

Methods: This is a single center non-randomized retrospective observational study.

Case of Recurrent Ventricular Fibrillations with Osborn Wave Developed during Therapeutic Hypothermia.

Therapeutic hypothermia (TH) has been used to protect neurological functions in cardiac arrest patient. Although Osborn wave is not pathognomonic of hypothermia, it is a well-known electrocardiogram finding of hypothermic patients. The cellular and ionic mechanisms of the Osborn wave have been suggested, and its relationship to tachyarrhythmias, such as ventricular tachycardia and ventricular fibrillation, is being explored.

Melatonin combined with exercise cannot alleviate cerebral injury in a rat model of focal cerebral ischemia/reperfusion injury.

Previous studies have demonstrated that melatonin combined with exercise can alleviate secondary damage after spinal cord injury in rats. Therefore, it is hypothesized that melatonin combined with exercise can also alleviate ischemic brain damage. In this study, adult rats were subjected to right middle cerebral artery occlusion after receiving 10 mg/kg melatonin or vehicle subcutaneously twice daily for 14 days.

Neuroprotective effect of citicoline against KA-induced neurotoxicity in the rat retina.

We examined whether citicoline has neuroprotective effect on kainic acid (KA)-induced retinal damage. KA (6 nmol) was injected into the vitreous of rat eyes. Rats were injected intraperitoneally with citicoline (500 mgkg-1, i.
