Fructose, zinc, prostate specific antigen (PSA), and neutral α-glucosidase (NAG) were analyzed as markers for the function of the epididymis, prostate and seminal vesicles [ 19].
An important issue in longitudinal analyses of a quantitative marker of the renal function is early study dropout [ 52] due to, e.g. initiation of kidney replacement therapy.
When used to model individual repeated values of a quantitative marker of the renal function, both linear mixed models and linear GEE can be used to investigate risk factors associated with the mean trajectory of the marker over time.
The observed correlations between structural parameters and renal function suggest that these parameters may potentially be useful as surrogate markers of the renal function.
Using eGFR and cystatin C, a novel marker of kidney function, the authors investigated the association of kidney function with multiple biomarkers in a diverse cohort.
In the presence of methylated OP metabolites a marker of the seminal vesicle function was also altered.
Measurement of seminal fructose used universally as a marker of the seminal vesicle function is not an appropriate approach due to its inverse relationship with the sperm count.
motile sperm concentration] multiplied by [seminal fructose concentration] has been shown to be a better marker of the seminal vesicle function [ 25].
To investigate the effects of dydrogesterone (DYD), a synthetic progestin largely used in hormone therapy, on the central nervous system by studying two markers of the neuroendocrine function: the neurosteroid allopregnanolone and the opioid β-endorphin.
Moreover, in cases of renal diseases of ischemic etiology, reduced tissue perfusion precedes the biochemical markers of the organ function limit [ 7].
Although a crude marker of kidney function, the creatinine peak was used to indicate the beginning of kidney function recovery, and consequent reduction of the effects of AKI exposure, similarly to RRT initiation.
