Experimental Gerontology, 1988
It is the purpose of this report to identify possible metabolic deficiencies that might serve as biochemical markers of aging. It is proposed that the multiplicity of physical and physiological changes associated with aging could be most readily explained by alterations in the regulation and/or the activities of enzymes that occupy central positions in

Research on Aging, 1986
From a life span perspective, aging occurs from birth to death, may involve reversible changes, and is a complex process that occurs interactively at the biological, psychosocial, and societal levels for historical cohorts. This article offers new conceptual distinctions among types of aging processes and argues for the application of specific dynamic ...

Inflammatory markers in schizophrenia in aged
Zhurnal nevrologii i psikhiatrii im. S.S. Korsakova, 2014To identify inflammatory markers in schizophrenia in aged.The main group included 29 patients with schizophrenia, mean age 72.1 ± 6.9 years. A comparison group comprised 34 patients with Alzheimer's disease, mean age 73.4 ± 7.9 years. Seven plasma inflammatory indicators were determined.There was a significant increase in the activity/content of acute ...

Aging hypothesis, aging markers and the concept of biological age
Experimental Gerontology, 1988The following two points are made in this article: (1) the likely existence of more than one underlying cause of senescence strengthens the case for the development of a number of reliable markers of aging and (2) the concept of a single biological or functional age for an organism should be used with great caution, if at all.

Constitutional genetic markers of aging
Experimental Gerontology, 1988Constitutional genetic markers of aging can be defined as members of that subset of genes that modulate the times of onset and/or the rates of progression of one or more of the processes of aging, or the response of the target cells, tissues and organisms to a particular process. These genetic factors are classified into: (1) those that control changes

Methanol as an ageing marker for in service transformers
2017 Annual Pulp, Paper And Forest Industries Technical Conference (PPFIC), 2017Measurement of transformer remaining useful life has long been a goal for responsible asset management. Most testing laboratories offer furan concentration testing as a suitable method. The interpretive method of choice is usually the Chendong equation expressed in practical terms as degree of polymerization of the paper with new paper at about 1000 ...

Kidney Diseases: The Age of Molecular Markers
2021Kidney diseases are conditions that increase the morbidity and mortality of those afflicted. Diagnosis of these conditions is based on parameters such as the glomerular filtration rate (GFR), measurement of serum and urinary creatinine levels and equations derived from these measurements (Wasung, Chawla, Madero.

Physiological system markers of aging
Experimental Gerontology, 1988Superficially physiological measurements and processes would appear to be excellent candidates to serve as biomarkers of aging. A considered analysis reveals that the validation of them as biomarkers of aging is difficult. The available evidence indicates that the concept of physiological age does not appear to be of much value.

Chrono-neuroendocrine markers of the aging brain
Aging Clinical and Experimental Research, 1996The study of the neuroendocrine changes occurring in aging may give information about the CNS functions, and also explain the impaired plasticity of the aged organism. In 16 elderly women and in 14 young controls, the circadian rhythms of plasma melatonin, GH, PRL, ACTH and cortisol, and of oral temperature were simultaneously studied.

Bone Mass???A Marker of Biologic Age?
Clinical Orthopaedics and Related Research, 1993One thousand one hundred ninety-two subjects who had the bone mineral content (BMC) of their forearm measured during the period spanning 1970-1976 were followed to 1985. At that time, 489 had died. Those who died had a lower BMC of the forearm at the time of the measurement than did the survivors.
