- ウイルス学
- 微生物群の研究
背景:
- リウマチ性関節炎 (RA) は,起源が不明な複雑な自己免疫疾患である.
- RAにおける微生物群の役割は研究されていますが,桃体ウイルスの貢献は不明です.
研究 の 目的:
- リウマチ性関節炎 (RA) における桃体ウイルスの変異を調査する.
- 桃腺ウイルスの 診断の可能性を評価する.
主な方法:
- 32人のRA患者と30人の健康な対照群 (HCs) の桃体サンプルをメタジェノミックシーケンシングした.
- ウイルス操作分類単位 (vOTU) の特定と分析
- 診断分類のための機械学習モデル (ランダムフォレスト).
主要な成果:
- RA患者では,桃体ウイルスの富と多様性が著しく減少した.
- 235のRA関連ウイルスのマーカーが特定され,そのうち13のマーカーがRAに濃縮された.
- ウイルスマーカーは,RAとHCを区別するために高い診断精度 (AUC 0. 960) を示した.
- トンジルウイルスの変異は免疫細胞のサブセットと相関しており,免疫機能不調の役割を示唆しています.
結論:
- 桃体ウイルスの有意な変化は,関節リウマチと関連しています.

Genome-wide Association Studies-GWAS
14.1K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Tonsillitis I: Introduction
546
Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology
Three primary contributing factors have been identified.

Viruses of Archaea
77
Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
57
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Chronic Pharyngitis
4.8K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
