The 24-hour serum profiles of bone markers in healthy older men and women [PDF]
Bone, 2019 The process of bone turnover displays variations over 24 h, with C-terminal cross-linked telopeptide of type 1 collagen (CTX) and osteocalcin exhibiting a nadir in the afternoon and a peak in the night. In contrast, N-terminal propeptide of type 1 procollagen (P1NP) did not display an apparent 24-hour rhythm.

Markers of cellular senescence in zero hour biopsies predict outcome in renal transplantation
Aging Cell, 2008 SummaryAlthough chronological donor age is the most potent predictor of long‐term outcome after renal transplantation, it does not incorporate individual differences of the aging‐process itself. We therefore hypothesized that an estimate of biological organ age as derived from markers of cellular senescence in zero hour biopsies would be of higher ...

Novel Markers in Zero-Hour Kidney Biopsies Indicate Graft Quality and Clinical Outcome
Transplantation, 2010In renal transplantation, allograft biopsies provide valuable diagnostic information indicating adverse allograft outcome posttransplantation. To uncover novel candidate markers characteristic of subtle inflammation and immune activation present during the intraoperative period, we investigated messenger RNA (mRNA) gene expression profiles in renal ...

Urine potassium per hour as a marker for renal potassium losses.
Journal of the Medical Association of Thailand = Chotmaihet thangphaet, 2012Hypokalemia, serum potassium (K) < 3.5 mEq/L, is a serious and common clinical problem. The traditional diagnosis of renal potassium losses is 24-hr urine potassium (24U(K)) > or = 20 mEq/day during hypokalemia. Immediate replacement of potassium is often required to prevent complication but may normalize serum K during 24-hr urine collection and ...

Volume Determination in 24-Hour Urine Specimens With Lithium as Exogenous Marker
Laboratory Medicine, 1983When added to urine containers before sample collection, lithium is easily dissolved and evenly distributed in 24-hour urine specimens. The degree of lithium dilution provides an external marker to evaluate urinary volume. This method was compared with conventional volumetric determinations by the use of a graduated vessel, as performed both in the ...

Is 24-hour urinary calcium a surrogate marker for dietary calcium intake?
Urology, 2005To determine whether the 24-hour urinary excretion of calcium was a reliable surrogate marker for dietary calcium intake. Although dietary calcium intake has been negatively correlated with the risk of recurrent calcium-based stones, detailed dietary histories are not routinely evaluated in most patients with recurrent stone formation.The dietary ...

Navigating coagulation: Key markers in the first 24 hours of pediatric ECMO
PerfusionBackground Anticoagulation in pediatric extracorporeal membrane oxygenation (ECMO) presents unique challenges due to developmental hemostasis, coagulation factor production, and response to anticoagulants. This process requires close monitoring to prevent bleeding and thrombotic events. Limited data exist on how

The effects of 40 hours of total sleep deprivation on inflammatory markers in healthy young adults
Brain, Behavior, and Immunity, 2007Inflammatory cytokines are released in response to stress, tissue damage, and infection. Acutely, this response is adaptive; however, chronic elevation of inflammatory proteins can contribute to health problems including cardiovascular, endocrine, mood, and sleep disorders.
