まとめ
アルドステロンとレニンの比率 (ARR) の上昇によって示されるサブクリニック原発アルドステロン症は,腎臓機能の低下がより迅速に起こることに関連しています. 低レニンのレベルは,血圧に関係なく,推定グルメルフィルタレーション率 (eGFR) の低下の増加と相関しています.

研究 の 目的:
- サブクリニカル・プライマリ・アルドステロニズムマーカーと推定グローメルーラ濾過率 (eGFR) の低下との関連を調査する.
主な方法:
- 976人のカナダ人成人 (40~69歳) を対象とした前向きなコホート研究.
- 測定されたアルドステロン,レニン,クレアチニン,シスタチンC.
- アルドステロン,レニン,アルドステロンとレニンの比率 (ARR) との関連性を評価するために,多変量線形混合回帰を用いて,eGFRの5~7年間の低下を評価した.
主要な成果:
- 高いARRは,時間の経過とともに11%の急激なeGFR減少と関連していました.
- 低レニンレベルは,時間の経過とともに16%の急激なeGFR減少と関連していました.
- アルドステロン単独では,eGFR変化と有意な関連性は示されなかった.
結論:
- 増加したARRと抑制されたレニンは,独立して加速されたeGFR減少と関連しています.
- これらの関連性は,血圧レベルに関係なく持続します.

Magnetic Declination
493
Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observer's location on Earth and is subject to changes over time due to the dynamic nature of the Earth's magnetic field.The declination is called eastern when magnetic north...

Primary Active Transport
201.1K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Primary and Secondary Growth in Roots and Shoots
60.7K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Primary Production
25.6K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

Primary Distribution
556
Primary distribution systems deliver electrical power from substations to consumers through various voltage classes, with 15-kV class voltages being predominant among U.S. utilities. Older 2.5- and 5-kV classes are being replaced by 15-kV primaries, while higher 25- to 34.5-kV classes are used in high-density urban areas and rural regions with long feeders. Three-phase, four-wire multigrounded systems are widely employed for balanced power delivery, using the neutral wire as a grounding point.
