Histone methylation in Epstein-Barr virus-associated diseases.

Epstein-Barr virus (EBV) infection is linked to various human diseases, including both noncancerous conditions like infectious mononucleosis and cancerous diseases such as lymphoma and nasopharyngeal carcinoma. After the initial infection, EBV establishes a lifelong presence and remains latent in specific cells. This latent infection causes changes in the epigenetic marks known as histone methylation.

Rapid Classification of Multilocus Sequence Subtype for Group B Based on MALDI-TOF Mass Spectrometry and Statistical Models.

Group B (GBS) is an important etiological agent of maternal and neonatal infections as well as postpartum women and individuals with impaired immunity. We developed and evaluated a rapid classification method for sequence types (STs) of GBS based on statistic models with Matrix-Assisted Laser Desorption/Ionization Time-of Flight Mass Spectrometry (MALDI-TOF/MS). Whole-cell lysates MALDI-TOF/MS analysis was performed on 235 well-characterized GBS isolates from neonatal invasive infections in a multi-center study in China between 2015 and 2017.
