背景:
- ハイパーウリケミア (HUA) は,治療の選択肢が少ない一般的な代謝障害です.
- Urolithin C (UroC) は,エルラギタニン豊富な食品に作用する腸内微生物から得られた代謝物です.
研究 の 目的:
- HUA管理におけるUroCの効果とメカニズムを調査する.
- HUA治療におけるUroCとUroAとUroBを比較する.
主な方法:
- UFLC-MS/MS分析で,UroCの活性形態をインビボで特定する.
- 血清尿酸 (SUA) レベルに対するUroCの影響を評価するために,HUAマウスを用いたin vivo試験.
- 酸化ストレス,線維症マーカー,およびROS-p38/ERK MAPK信号伝達経路を含むメカニズム研究.
主要な成果:
- UroCはHUAマウスのSUAレベルを著しく低下させ,UroAとUroBを上回った.
- 自由なUroCは,主たる活性形態としてin vivoで特定された.
- UroCは腎臓の尿酸分泌を増加させ,腎臓の酸化ストレスと線維症を減少させた.
- UroCは,ROSの生成を低下させ,UA誘発のp38/ ERK MAPK活性化を抑制した.
- 救助実験では,p38/ERK MAPK阻害によるUAトランスポーターと線維症マーカーの関与によるUroCのメカニズムが確認されました.
結論:
- ウロリチンCは,高尿血症の管理のための強力な食品由来代謝物質です.

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Management of renal calculi focuses on effective strategies like tailored nutrition and hydration therapy. Adjusting diet and fluid intake reduces stone formation and recurrence, making these interventions simple yet powerful in kidney stone prevention and management.Understanding Kidney StonesKidney stones form when calcium, oxalate, uric acid, and cystine concentrate and crystallize in urine. Factors contributing to their formation include genetic predisposition, certain medical conditions,...

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...
