まとめ
女性の全身性硬化症 (SSc) 患者は,第2桁から第4桁の比率が低い (2D:4D) であり,妊娠前のアンドロゲン被曝がより高いことを示しています. これは,産前ホルモン環境がSScの感受性に影響を与える可能性があることを示唆しています.
科学分野:
- エンドクリノロジー エンドクリノロジー
- リーマトロジーの病理学
- 免疫学 免疫学とは
背景:
- システミック硬化症 (SSc) は主に女性に影響を与え,その病原性におけるホルモン要因を示唆しています.
- 第2~4桁の比率 (2D:4D) は,産前アンドロゲン被曝のバイオマーカーであり,自己免疫疾患と関連している.
研究 の 目的:
- 女性のSSc患者と健康な対照群の2D:4D比の違いを調査する.
- SScの感受性における産前ホルモン環境の潜在的な役割を調査する.
主な方法:
- 33人の女性SSc患者と30人の健康な女性対照群を対象としたケース・コントロール研究.
- 2D:4D比を計算するためにデジタルキャリパーを使用して,第2桁と第4桁の長さの双方向測定.
- グループを比較するためにウェルチのtテストとマン・ウィトニーUテストを用いた統計分析.
主要な成果:
- SScの患者は,対照群と比較して,双方の2D:4D比が著しく低いことを示した (p <0.001).
- 低い比率は,より長い4桁の数字に起因し,妊娠前のアンドロゲン被曝が増加していることを示唆しています.
- 効果の大きさはかなり大きかった (Cohen's d > 2.8).
結論:
- 女性のSSc患者は2D:4D比が著しく低いことを示しており,妊娠前のテストステロンの曝露がより高いことを示唆しています.
- これらの発見は,産前ホルモン環境がSSc.における自己免疫疾患の感受性に寄与する可能性があるという仮説を支持する.

The Evidence for Evolution
48.4K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Infertility in Females
4.9K
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.

Poisson's Ratio
1.4K
Poisson's ratio is a material property that indicates their stress response. It explains the connection between the elongation or compression a material undergoes in the direction of an applied force and the contraction or expansion it experiences perpendicular to that force. When a slender bar is loaded axially, it stretches in the direction of the force and contracts laterally. Poisson's ratio is the negative ratio of this lateral contraction to the axial elongation. The negative sign...

Odds Ratio
1.9K
The odds ratio (OR) is a statistical measure used extensively in epidemiology and research to quantify the strength of association between exposure and outcome across different groups. Unlike relative risk, which compares the probabilities of an event occurring, the odds ratio compares the odds of an event occurring in the exposed group to the odds of it occurring in the unexposed group. The odds, in this context, are calculated as the probability of the event happening divided by the...

External Female Genitals
36.1K
The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more...

Disorders of the Female Reproductive System
4.5K
The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...
