まとめ

硬水や大気汚染などの環境要因は,年齢関連の難聴 (ARHL) のリスクを高め,自然は保護的である. 遺伝的傾向は,ARHLに対するこれらの環境的影響を大きく変えない.

科学分野:

遺伝学と環境衛生について
エピデミオロジーエピデミオロジー
耳鼻喉科 (Otorhinolaryngology) は,耳鼻喉科 (Otorhinolaryngology) を専門とする医療機関である.

背景:

年齢に関連した難聴 (ARHL) は,遺伝的および環境的要因の影響を受ける複雑な状態です.
これらの影響を理解することは,効果的な予防と管理戦略の開発に不可欠です.

研究の目的:

ARHLリスクに対する遺伝的感受性および環境被曝の独立した相互作用的影響を調査する.
ARHLの特定の環境リスクと保護要因を特定する.

主な方法:

UK Biobankのデータとメタ解析を用いた大規模なケース・コントロール研究.
多変数ロジスティック回帰と多遺伝子リスクスコア (PRS) の構築により,遺伝的および環境的な主な影響を評価する.
遺伝子環境相互作用の分析とPRS層化された分析,複数の比較でFDR修正.

主要な成果:

硬水,炭酸カルシウム,およびカルシウム濃度がARHLの危険因子として特定され,マグネシウムは保護効果を示した.
大気汚染物質はARHLのリスクを高め,緑地,青い空間,自然環境は保護的であった.
重要な遺伝子環境相互作用は見つかりませんでしたが,環境の影響は遺伝的背景から独立して作用することを示唆していますが,中間的な遺伝的リスクのある個人は炭酸カルシウムに対する感受性が高くなっています.

結論:

環境要因は,ARHLにおいて独立して重要な役割を果たします.
高カルシウム水と大気汚染は,自然環境の保護的な利点と対照的に重要な環境リスク要因です.
遺伝的リスクに関係なく,環境的曝露をターゲットとする介入は,中等遺伝的感受性のある人のカルシウム炭酸曝露に潜在的に焦点を当てて,ARHLの予防に有益である可能性があります.

Factors Affecting the Risk of Infection

13.8K

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Hearing

57.5K

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Gene-Environment Interactions

1.2K

Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Loss of Tumor Suppressor Gene Functions

6.1K

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Line Loss

547

The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...

Transcription Factors

82.9K

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...
