In the present study, we investigated the influence of cytological stains in analyzing DNA extracted from cytological slides by comparative genomic hybridization (CGH). Multiple imprint cytological slides were prepared for fresh-frozen breast cancer tissue samples and the slides were stained by three staining methods for each sample. Under microscopic observation, cancer cells were selectively ...

BACKGROUND Self-collection of anorectal swab specimens could greatly facilitate the completion of prerequisite studies and future implementation of anal cancer screening among men who have sex with men (MSM). We therefore compared self- versus clinician- collection procedures with respect to specimen adequacy for cytological evaluation, concordance of paired cytological results, and concordance...

Purpose: The incidence of invasive anal cancer (IAC) has been increasing among human immunodeficiency virus (HIV)-positive men who have sex with men (MSM). Although cytological diagnosis is the modality of choice for screening cases of IAC, it is associated with lower sensitivity and specificity. Therefore, the present study aimed to evaluate new cytological signs of human papillomavirus (HPV) ...

Since most primary carcinomas of the lung are bronchogenic they tend to exfoliate cells into the bronchial lumen. The normal current of the bronchial secretions acts as a constant natural' "curettage" carrying these cells upward in the sputum. It has been demonstrated1 that neoplastic cells can be recognized in the sputum, after suitable preparation, in over 80 per cent of cases of proved carci...

The cytological Ki-67 expression measured on cytological samples collected by endoscopic ultrasonography-guided fine needle aspiration cytology (EUS-FNAC) may provide pre-operative indications for pancreatic endocrine tumours (PETs) management. The aim of our study was to assess reliability of Ki-67 expression measured on cytological samples obtained by EUS-FNAC in patients with PETs. Eighteen ...

UNLABELLED PREMISE OF THE STUDY Hybridization is an important evolutionary force in the history of angiosperms; however, there are few examples of stabilized species derived through homoploid hybrid speciation. Homoploid hybrid species are generally detected via the presence of genetic additivity of parental markers, novel ecological and spatial distinctions, and novel morphological traits, ...

Cnidium officinale is an important medicinal crop grown in Asia for its pharmacological properties. In this study, tetraploid breeding was conducted to increases the content of compound and tolerance environmental conditions using vitro shoot culture C. officinale. For this, we generated plants oryzalin, a chromosome doubling agent, compared morphological traits, cytological characteristics, he...

Tomatoes are usually consumed daily in the human diet. High temperatures reduce number of tomato yields per year. Heat stress has been considered one most prominent causes alterations morphological and molecular characteristics crops that decrease normal growth, production, yield diverse plants, including tomatoes (Solanum lycopersicum L.). In this study, we evaluated six lines, namely G1, G2, ...

Cytological evaluation of cutaneous and mucosal tumors presents a diagnostic challenge. Preoperative diagnosis is of great importance for the right choice of treatment, in the maxillofacial surgery. The recognition of the lesions may be accomplished by clinical, radiological, cytological and histopathological examination. Cytological examination of cutaneous tumors is not as yet a well recogniz...

introduction: in the present study we attempted to investigate the alterations of cytological parameters of nrm (longaxis and intranuclear rods) in the absence of its excitatory vl pag afferent with or without the formalin pain model. materials and methods: we used male rats in 4 groups: 1- control group (n=4), 2- formalin group (n=4), 3- chemical lesion of vl pag by ibotenic acid (0.2 َl, 0.5 َl...
