Also check you are using Java 11 with the javax.swing package, and that you do not have a previous version of Java 11 installed.
If you have already installed Java 11 check you Java version by executing java -version in the command line. You may have installed Java 11 while Java 8 was still active on your system and that may be why the error message is triggered.
Lupus nephritis: immunological and histological evaluation.
Lupus nephritis (LN) represents a severe complication of systemic lupus erythematosus (SLE), with poor prognosis and high morbidity. This disease is characterized by a complex interplay between immune and non immune cells and inflammatory molecules. Our study aimed to perform a semiquantitative evaluation of renal biopsies in a cohort of patients with LN and correlate this parameter with the histopathological features of the disease. Sixty-six patients with LN were included in the study. All patients had histological class V LN and were biopsied between 1994 and 2003. Semiquantitative evaluation of the biopsies was performed according to the Oxford classification criteria, based on four parameters: glomerular involvement, tubulointerstitial involvement, vascular involvement and activity and chronicity. A linear correlation between the semiquantitative scores and the histological parameters of the disease was found, however the concordance was poor for vascular and tubulointerstitial involvement. Semiquantitative evaluation, combined with histological classification of LN, may help in the evaluation of the activity and prognosis of the disease.INTRODUCTION {#sec1-1}
============
Acute kidney injury (AKI) in the absence of obstructive uropathy is a common cause of acute renal failure (ARF) in hospitalized patients. These patients may present with severe hemodynamic instability as a result of blood volume depletion. To the best of our knowledge, we describe for the first time the renal vein compression in a patient with AKI secondary to sepsis and tachycardia.
