900 MHz electromagnetic field exposure affects qualitative and quantitative features of hippocampal pyramidal cells in the adult female rat
(0-Belirlenecek, 2009)The effects of electromagnetic fields (EMFs) emitted by mobile phones on humans hold special interest due to their use in close proximity to the brain. The current study investigated the number of pyramidal cells in the ... -
The assessment of neuronal plasticity following sciatic nerve injuries in rats using electron microscopy and stereological methods
(Elsevier, 2024)The transmission of signals to the cell body from injured axons induces significant alterations in primary sensory neurons located in the ganglion tissue, the site of the perikaryon of the affected nerve fibers. Disruption ... -
Chronic prenatal exposure to the 900 megahertz electromagnetic field induces pyramidal cell loss in the hippocampus of newborn rats
(Sage, 2009)Widespread use of mobile phones which are a major source of electromagnetic fields might affect living organisms. However, there has been no investigation concerning prenatal exposure to electromagnetic fields or their ... -
The effect of acute organophosphate intoxication on female rat hippocampus cornu ammonis region pyramidal neuron numbers, biochemistry and morphology
(Elsevier, 2019)Background: the most commonly used insecticides and pesticides worldwide are organophosphate compounds, chemicals that irreversibly inhibit the cholinesterase enzyme. Acute intoxication with cholinesterase inhibitors is ... -
Effect of prenatal exposure to diclofenac sodium on the male rat arteries: A stereological and histopathological study
(Taylor & Francis Ltd., 2013)In this study, we investigated the morphometric and histological alterations of the aorta, brachial, and femoral arteries in 4- and 20-week-old rats that were prenatally exposed to diclofenac sodium (DS). For this purpose, ... -
Effects of diabetes and ovariectomy on rat hippocampus (A biochemical and stereological study)
(Taylor & Francis Online, 2012)Oxidative stress is one of the main reasons of both menopause and diabetes. So, it plays crucial role in the pathogeneses of that condition and disease. Therefore, the objective of the present study was to investigate the ... -
The effects of Garcinia kola and curcumin on the dorsal root ganglion of the diabetic rat after peripheral nerve transection injury
(Elsevier, 2024)Objective: To test the protective effects of Garcinia kola and curcumin on the ganglion tissues of diabetic rats following the use of autologous vein graft in peripheral nerve transection injury. Methods: The sciatic nerve ... -
Estimation of cerebral surface area using vertical sectioning and magnetic resonance imaging: A stereological study
(Elsevier, 2010)Stereological techniques using isotropic uniform random and vertical uniform random sections have been used for surface area estimation. However, there are a few studies in which the surface area of the brain is estimated ... -
Evaluation of cerebellar asymmetry in Alzheimer's disease: A stereological study
(Karger, 2009)Objectives: Alzheimer's disease (AD) is the most common cause of dementia and, as previous studies have indicated, degenerative changes in the cerebellum occur in AD. It is well known that the cerebellum does not have a ... -
Evaluation of cerebellar asymmetry with vertigo cases: A stereological study
(Turkish Neurosurgical Society, 2009)Aim: We aimed to evaluate the relevant methods of stereology to estimate cerebellar asymmetry according to gender in both adult right-handed vertigo cases and healthy cases. Material and Methods: The study included 14 adult ... -
The histomorphological and stereological assessment of rat dorsal root ganglion tissues after various types of sciatic nerve injury
(Springer, 2023)Peripheral nerve injuries lead to signifcant changes in the dorsal root ganglia, where the cell bodies of the damaged axons are located. The sensory neurons and the surrounding satellite cells rearrange the composition ... -
Light color changes the density and height of synapses in an area of the brain essential for learning
(2010)The effects of pre and post-passive avoidance training, and exposure to different wavelengths of light on numerical synapse density and the mean projected synapse height in the intermediate and medial part of the hyperstriatum ... -
Morphometric analysis of Hemicerebellar Asymmetry with Central Vertigo cases: A Stereological study
(2010)We aimed to evaluate the relevant methods of stereology to estimate hemicerebellar asymmetry according to sex in both adult right handed vertigo cases and comparing with healthy cases. The study included 14 adult control ... -
Nitric oxide synthase inhibitors protect cerebellar Purkinje cells from zinc-induced cell loss in adult rat
(0-Belirlenecek, 2011)Zinc is an important trace element in biological systems; however, excessive extracellular zinc could lead to neuronal cell death following ischemia, seizures, and brain trauma. In this study, we investigated whether the ... -
Numerical analysis of age and gender-dependent neuronal cells in postnatal development of rat hippocampus
(0-Belirlenecek, 2013)The hippocampus, phylogenetically one of the most ancient parts of the central nervous system, is both a highly developed structure of the mammalian brain that plays a role in complex brain functions and one of the brain ... -
Purkinje cell number decreases in the adult female rat cerebellum following exposure to 900 MHz electromagnetic field
(Elsevier, 2010)The biological effects of electromagnetic field (EMF) exposure from mobile phones have growing concern among scientists since there are some reports showing increased risk for human health, especially in the use of mobile ... -
A stereological study of MRI and the Cavalieri principle combined for diagnosis and monitoring of brain tumor volume
(Elsevier, 2010)In this study, we aimed to describe the application of the Cavalieri principle for the assessment of tumor volume using MRI without an over-projection/estimation effect. For this purpose, the volume of a patient's brain ...
