A comparative study for selectivity of micronuclei in oral exfoliated epithelial cells

Journal of Cytology, 2012
Background: Micronucleus (MN) represents small, additional nuclei formed by the exclusion of chromosome fragments or whole chromosomes lagging at mitosis. MN rates, therefore, indirectly reflect chromosome breakage or impairment of the mitotic apparatus.

The Ticking Clock: Differential Time‐Dependent Deterioration Between Washed and Thawed Sperm

Andrology, EarlyView.
ABSTRACT Background Cryopreservation is widely used in assisted reproductive technologies. While fresh sperm undergoes gradual time‐dependent deterioration, it remains unclear whether thawed sperm exhibits a more accelerated decline. Objectives To directly compare the rate of deterioration in sperm motility, vitality, and DNA fragmentation between ...

Unusual Cytology Features of A DICER1‐Mutated Thyroid Nodule: Raising Awareness of A Potential Diagnostic Pitfall During Fine Needle Aspiration

Cytopathology, EarlyView.
This article describes the unusual cytology features of a DICER1‐mutated thyroid nodule. Fine needle aspiration revealed predominantly cell debris/degenerated cells and rare viable follicular cells with mild cytologic atypia. Surgical resection revealed a nodule with nearly complete infarction, which is one specific feature of DICER1‐mutated thyroid ...

Comparison of honey with ethanol as an oral cytological fixative: A pilot study

Journal of Cytology, 2015
Introduction: The fixation of cytological smears using ethanol is the gold standard. But, there exists a quench to search a new alternative for it due to it being expensive, carcinogenic and not freely available.

Impact of Electronic Nicotine Delivery Systems on Oral Mucosa: A Cytopathological and Molecular Study

Journal of Oral Pathology &Medicine, EarlyView.
ABSTRACT Background The packaging and marketing of electronic cigarettes (e‐cigs) often target younger demographics. This study aimed to evaluate gene expression in e‐cig users through exfoliative cytology. Methods Samples were collected from 17 e‐cig users and 10 nonsmokers as controls.

Leishman Giemsa cocktail as a new, potentially useful cytological technique comparable to Papanicolaou staining for oral cancer diagnosis

Journal of Cytology, 2013
Background: Papanicolaou staining is commonly used for staining exfoliative cytology smears with Romanowsky stains being used sparingly. Leishman Giemsa (LG) cocktail, being a relatively new staining technique, has not been used in exfoliative cytology ...

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

The Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Evaluation of diagnostic reliability of micronuclei in potentially malignant disorders of oral cavity

CHRISMED Journal of Health and Research, 2014
Context: Micronucleus (MN) has been proved to be an important biomarker of genomic damage. MN scoring in oral exfoliated epithelial cells has been used in the past as a biomarker to identify different preneoplastic conditions much earlier than the ...

Five Cases of Hepatic Mesenchymal Tumors Diagnosed by Endoscopic Ultrasound‐Guided Tissue Acquisition

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Percutaneous biopsy remains the gold standard for diagnosing focal liver lesions; however, endoscopic ultrasound‐guided tissue acquisition (EUS‐TA) has recently emerged as a promising alternative. Although its diagnostic performance is favorable, most available evidence has focused on epithelial tumors, and reports on mesenchymal tumors are ...
