Age Determination of Brain Contusions

Forensic Science, Medicine and Pathology, 2006
In 104 individuals who had sustained traumatic brain injury, the course of traumatically induced morphological changes was investigated immunohistochemically during the first 30 weeks after the trauma. Regarding the inflammatory cell reaction in human cortical contusions, CD15-labeled granulocytes were detectable within 10 minutes following brain ...

Determinants of Institutionalization in Old Age

1996
Institutionalization in old age is expensive and most elderly prefer to stay independent and live at home as long as possible. Therefore, a vital interest exists for the individual as well as for the society to learn about the risks of institutionalization and about the determinants which either cause or avoid institutionalization.

Determining the initial age distribution for an age structured population

Mathematical Population Studies, 1991
"This paper deals with an inverse problem in age-structured population dynamics; the recovery of an unknown initial age distribution. We attempt to recover this function from overposed data which consists of either the total population over a time interval equal to the maximum life span of the species or the age structure of the population at a fixed ...

Determination of Interlayer Diffusion Parameters for Ag/Ag(111)

Physical Review Letters, 2000
It is well known that the Ag/Ag(111) epitaxial system grows three dimensionally because of the existence of a relatively high excess diffusion barrier, DeltaE(s) = 0.13 eV, at the step edges. Several experimental methods have been developed to measure the step edge barrier in this system over a wide coverage range.

Age Determination and Longevity in Amphibians

Gerontology, 2009
Methods of age determination of amphibians by counting annual layers in the bone tissue and data on longevity of amphibians (both anurans and urodeles) in nature are presented. Age compositions of amphibian populations are discussed and their variations analysed.

Age Determination and Longevity in Fishes

Gerontology, 2009
It is possible to determine the age of fishes with reasonable accuracy by reading the ‘growth rings’ (annuli) in hard parts (scale, otolith, opercular bone, vertebra and cross-section of dorsal or pectoral spine and fin rays). Primary growth increments in ‘otoliths’ can also be used as an alternative method of age determination. The traditional methods

Determinants of onset age in Friedreich’s ataxia

Journal of Neurology, 1998
We studied the factors that might influence onset age in Friedreich's ataxia in 41 cases (20 male, 21 female) homozygous for GAA expansion on the first intron of X25 gene. Patients came from 18 multiplex families (13 couples, 5 triplets). Mean age (SD) was 18.1 (8.9) years and did not differ by gender.

Age Determination in Antarctic Fish

1991
The determination of age is an essential component in understanding the life history of fish, and is important in the assessment of the population dynamics of species to provide the data necessary to enable effective conservation and fisheries management.

Age Determination in Mansonioides Mosquitoes

Nature, 1959
OBSERVATIONS by Bertram and Samawickrema1 have shown that it is possible to determine the number of times that Mansonioides mosquitoes have laid eggs by examination of the ovaries for corpora lutea, a technique developed by Russian workers using Anopheles maculipennis 2.

Intracellular determinants of cell aging

Mechanisms of Ageing and Development, 1984
Several important findings have been made since our observation that normal human and animal cells have a finite capacity to replicate and function. Among these are that: an inverse relationship exists between donor age and population doubling potential; more than 100 functional increments and decrements occur in cultured normal human cells before they
