Sonographic Determination of Gestational Age

The Ultrasound Review of Obstetrics and Gynecology, 2005
Appropriate assessment of gestational age is paramount in obstetric care. Making appropriate management decisions requires accurate appraisal of gestational age. Accurate pregnancy dating may assist obstetricians in appropriately counseling women who are at risk of a preterm delivery about likely neonatal outcomes and is also essential in the ...

A method for determining the age of a bloodstain

Forensic Science International, 2005
DNA allows for the unambiguous identification of the person from whom a biological sample was derived but provides little information about when the sample was deposited. This information only indicated that the biological material was deposited at the crime scene prior to the collection of evidence.

Stroke Rehabilitation—Is Age a Determinant?†

Journal of the American Geriatrics Society, 1980
ABSTRACT A retrospective survey was made of the average improvement, length of stay, and discharge placement of 180 stroke patients admitted to a rehabilitation hospital. The patients were divided into four age groups: under 55, 55–65, 66–75, and over 75. A grading system was used for evaluating the patient's ability in ambulation and

Infection determinants at extremes of age

Journal of Antimicrobial Chemotherapy, 1994
The immune defence of the full-term neonate is compromised in several ways. Although adequate numbers of B lymphocytes are present, antibody production may be delayed compared with the adult. Decreased levels of complement components contribute to the impaired opsonization potential of newborn sera and in turn, to impaired chemotactic responses of ...

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, 1994
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, 1994
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
