ESTIMATING TOTAL GLOMERULAR NUMBER IN HUMAN KIDNEYS WITH A PHYSICAL DISECTOR/FRACTIONATOR COMBINATION

open access: yesImage Analysis and Stereology, 2011
End-stage renal disease (ESRD) has emerged as a major health issue for Australian Aborigines. This phenomenon is paralleled in other populations that have adopted a Westernised lifestyle, including African Americans.

Does the physical disector method provide an accurate estimation of sensory neuron number in rat dorsal root ganglia? [PDF]

open access: yesJournal of Neuroscience Methods, 2009
The physical disector is a method of choice for estimating unbiased neuron numbers; nevertheless, calibration is needed to evaluate each counting method. The validity of this method can be assessed by comparing the estimated cell number with the true number determined by a direct counting method in serial sections.

Practicable methods for histological section thickness measurement in quantitative stereological analyses. [PDF]

open access: yesPLoS ONE, 2018
The accuracy of quantitative stereological analysis tools such as the (physical) disector method substantially depends on the precise determination of the thickness of the analyzed histological sections.

Stereological estimates of nuclear number in human ventricular cardiomyocytes before and after birth obtained using physical disectors [PDF]

open access: yesJournal of Anatomy, 1997
Design‐based stereology is employed to estimate total numbers of myocyte nuclei and mean myocyte volume per nucleus in ventricles of fetal and early postnatal human hearts. Organs were collected postmortem from subjects varying in age from 16 gestational wk to 40 postnatal wk.

ESTIMATING NUMBER DENSITY NV – A COMPARISON OF AN IMPROVED SALTYKOV ESTIMATOR AND THE DISECTOR METHOD

open access: yesImage Analysis and Stereology, 2011
Two methods for the estimation of number per unit volume NV of spherical particles are discussed: the (physical) disector (Sterio, 1984) and Saltykov's estimator (Saltykov, 1950; Fullman, 1953).

Cell counting in human endobronchial biopsies--disagreement of 2D versus 3D morphometry. [PDF]

open access: yesPLoS ONE, 2014
QUESTION: Inflammatory cell numbers are important endpoints in clinical studies relying on endobronchial biopsies. Assumption-based bidimensional (2D) counting methods are widely used, although theoretically design-based stereologic three-dimensional (3D)

Estimation of Total Glomerular Number Using an Integrated Disector Method in Embryonic and Postnatal Kidneys

open access: yesCanadian Journal of Kidney Health and Disease, 2014
Congenital Anomalies of the Kidney and Urinary Tract (CAKUT) are a polymorphic group of clinical disorders comprising the major cause of renal failure in children. Included within CAKUT is a wide spectrum of developmental malformations ranging from renal

ANALYSIS OF STRUCTURAL PLASTICITY IN THE HONEY BEE BRAIN USING THE CAVALIERI ESTIMATOR OF VOLUME AND THE DISECTOR METHOD

open access: yesImage Analysis and Stereology, 2011
The antennal lobe of the worker honey bee has been used as a model system to address the origins of structural plasticity in the central nervous system.
