A Systematic Review on Predisposition to Lymphoid (B and T cell) Neoplasias in Patients With Primary Immunodeficiencies and Immune Dysregulatory Disorders (Inborn Errors of Immunity)
Conclusions Though this is not a comprehensive summary of malignancies in PIDDs, or even lymphoproliferative disease in this area, this review summarizes the Medline-indexed published reports of B and T lymphomas in patients with PIDDs. This report highlights the diversity of malignant lymphoproliferative disorders in setting of PIDDs, and its associated challenges of diagnosis and treatment. The pathological classification and nomenclature for the lymphoid malignancies with variably reported and postulated underlying mechanisms were inconsistent and inadequate for many of these published reports. A wide range of treatmen...

The Study of Dried Ginger and Linggan Wuwei Jiangxin Decoction Treatment of Cold Asthma Rats Using GC –MS Based Metabolomics
Conclusion In this study, serum and urine metabolites identified by GC–MS and general pharmacodynamic evaluation (morphological observation, histopathology, inflammatory factors, and visceral indices) were used to compare the effects of GJ and LGWWJX decoctions on cold asthma. Significant metabolic abnormalities were observed for 37 metabolites (15 in serum, 22 in urine) in rats with cold asthma. These altered metabolites might be potential biomarkers or therapeutic targets during development of cold asthma. Furthermore, pathway analysis demonstrated that pathways associated with energy metabolism and oxidative str...

Maternal Exposure of BALB/c Mice to Indoor NO2 and Allergic Asthma Syndrome in Offspring at Adulthood with Evaluation of DNA Methylation Associated Th2 Polarization
Conclusions: Maternal exposure to indoor environmental NO2 causes allergic asthma-related consequences in offspring absent any subsequent lung provocation and potentiates the symptoms of allergic asthma in adult offspring following postnatal allergic sensitization and challenge; this response is associated with the Th2-based immune response and DNA methylation of the IL4 gene. https://doi.org/10.1289/EHP685 Received: 19 June 2016 Revised: 07 June 2017 Accepted: 19 June 2017 Published: 13 September 2017 Address correspondence to N.
