background and objective: smoking can be associated with the decreasing gingival blood flow and epithelial changes. the aim of this study was to evaluate the histopathological changes of gingival epithelium and connective tissue in smokers. methods: the study was case-control. sixty male patients (28 smokers and 32 nonsmokers) suffering chronic periodontitis were participated in the study. peri...

introduction: this study was designed to investigate the characters of the human endometrial epithelial cells when cultured on either plastic or ecm (extracellular matrix) gel surface and to study ultrastructural features of cultured cells in comparison to endometrial tissue. material and methods: human endometrial tissue was obtained from patients who had undergone hysterectomy for uterine myo...

Circulating tumor cells (CTCs) and circulating cancer-associated fibroblasts (cCAFs) have been individually considered strong indicators of cancer progression. However, technical limitations prevented their simultaneous analysis in the context CTC phenotypes different from epithelial. This study aimed to analyze CTCs cCAFs simultaneously peripheral blood 210 breast patients using DAPI/pan-kerat...

Allergic diseases have been increasing recently and affect nearly 20% of the human population, including 200 million people with atopic dermatitis (AD), 250 food allergies, 600 allergic rhinitis or asthma. The march is concept whereby having early-in-life AD a dysfunctional skin barrier during initial allergen sensitization increases predisposition at distant epithelial sites (e.g., asthma). We...

Background  To report normal variations of the limbal structures using in vivo laser scanning confocal microscopy. Methods: This was a retrospective study of fourteen eyes from 11 healthy individuals. Confocal imaging of cornea and limbus was performed using Heidelberg Retina Tomograph III Rostock Corneal Module. Results: The typical structure of the palisades of Vogt (POV) was detected ...

Morphological and histochemical study of the abomasal epithelium in camel (Camelus dromedarius) wascarried out by light and scanning electron microscopes. The lining of the abomasum was divided into fourregions, i.e. cardiac, pseudocardiac, fundic and pyloric. Our investigation revealed that the cardiac andpseudocardiac regions occupy a wide part of the abomasum in camel and it reaches approxim...

The aim of this study was to investigate changes in immunoreactivity of Ras and Raf-1 in lung epithelial cells of rats exposed to carcinogen NNK after swimming training. 50 Wistar rats were randomly divided into five groups: control, training, training + NNK, NNK and sham. NNK-induced groups received NNK Subcutaneously once a week at a dose of 12/5 mg per kg body weight for 12 weeks. The exerci...
