Background: The anti-melanoma differentiation-associated gene 5 (anti-MDA5) antibody-positive dermatomyositis is known for its association with rapidly progressive interstitial lung disease (RP-ILD) and ulcerative skin lesions, often presenting with or without muscle involvement. The aim of this study was to identify distinct clinical and laboratory features that could be used to evaluate disease progression in an ethnically diverse cohort of anti-MDA5 dermatomyositis patients at a U.S.

The impact of clinical stage on the effectiveness of osimertinib for epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer (NSCLC) remains unexamined. We investigated osimertinib therapeutic efficacy variation between stage IVA or lower and stage IVB EGFR mutation-positive lung cancers, focusing on differences in pretreatment co-occurring genetic alterations in circulating tumor DNA. This was a secondary analysis of the ELUCIDATOR study, a multicenter prospective observational study in Japan that assessed the mechanisms underlying resistance to osimertinib as a first-line treatment for advanced NSCLC with EGFR mutations.

Understanding the causes of past atmospheric methane (CH) variability is important for characterizing the relationship between CH, global climate and terrestrial biogeochemical cycling. Ice core records of atmospheric CH contain rapid variations linked to abrupt climate changes of the last glacial period known as Dansgaard-Oeschger (DO) events and Heinrich events (HE). The drivers of these CH variations remain unknown but can be constrained with ice core measurements of the stable isotopic composition of atmospheric CH, which is sensitive to the strength of different isotopically distinguishable emission categories (microbial, pyrogenic and geologic).

Associations between genetic variations in oxytocin pathway genes and hippocampal volume: Insights from the UK Biobank.

Cortex

The role of oxytocin-related genes in social-cognitive function has been previously established, but structural brain mechanisms underlying this link remain poorly understood. Utilizing a substantial dataset from the UK Biobank (N ≈ 30,000), this research determined associations between variations in ten single nucleotide polymorphisms (SNPs) within three oxytocin pathway genes (i.e.
