Competitive pressure to maximize the current bibliometric measures of productivity is jeopardizing integrity scientific literature. Efforts are underway address ‘reproducibility crisis’ by encouraging use more rigorous, confirmatory methods. However, as long continues be defined number discoveries scientists publish, impact factor journals they publish in and times their papers cited, will reluctant accept high quality methods consistently conduct confirmatory/replication studies. This...

Abstract Hyperinflammation and lymphopenia provoked by SARS-CoV-2-activated macrophages contribute to the high mortality of Coronavirus Disease 2019 (COVID-19) patients. Thus, defining host pathways aberrantly activated in patient is critical for developing effective therapeutics. We discovered that G9a, a histone methyltransferase overexpressed COVID-19 patients with viral load, activates translation specific genes induce hyperinflammation impairment T cell function or lymphopenia. This...

Objective Lupus nephritis (LN) is a major cause of morbidity and mortality in systemic lupus erythematosus (SLE). Despite multiple studies addressing healthcare disparities, disparate outcomes LN persist. We investigate herein the association between socioeconomic status (SES) as well SES, SLE disease activity index (SLEDAI), treatment response. Methods Patients were selected from Southern California Registry (SCOLR), registry enrolling all-comers with SLE. Analysis was completed on...
