Oesophageal adenocarcinoma represents the 6th common cause of cancer related deaths. Frequently oesophageal adenocarcinomas are developed from Barret’s oesophagus, which metaplastic lesion lower third when squamous epithelium is replaced by glandular epithelium. It has been shown, that metaplasia bears risk progression into dysplasia and later malignant disease. However, this different in patie...

The current study was conducted to find out the most important histological and histochemistry differences in bird A. trisris intestine. samples were dissected; remove fixed 10% formalin, preparing them for histochemical study. results showed there a Histological sections that mucosa of tristis small intestine presented numerous long villi which lined by simple columnar epithelium. In large wit...

Pathological conditions of the tracheal epithelium, such as postoperative injuries and chronic conditions, often compromise functionality respiratory epithelium. Although replacement epithelium using various types transplantation has been attempted, there is no predictable dependable method that holds for safe practicable long-term use. Therefore, we used a tissue engineering approach ex vivo r...

Gene silencing by feeding double-stranded (dsRNA) holds promise as a novel pest management strategy. Nonetheless, degradation of dsRNA in the environment and within insect gut, well inefficient systemic delivery are major limitations to applying this Branched amphiphilic peptide capsules (BAPCs) complexed with have been used successfully target genes outside inside gut epithelium upon ingestion...

background: the langerhans cells (lcs) are dendritic cells (dcs) which belong to the group of antigen presenting cells (apcs). their function is to recognize the antigen, capture it, and present it to the t lymphocytes; thus initiating an early immune response. the antigen presenting functional lcs may play an important part in initiation and development of gingivitis. the aim of this study was...

Homeostasis of the epithelium is depend-ent on Wnt/beta-catenin pathway, which regulates proliferation intestinal stem cells. The gain function mutations in beta-catenin gene leads to rapid cell and malignant growth epithelium. In addition, maintenance these cells appears be linked mesenchymal-derived factors. Although communication between epithelial mesenchyme populations remains uncharacteri...

The central odontogenic fibroma (COF) is a rare benign mesenchymal tumour of jaw bone derived from the ectomesenchyme. It characterized by fibrous mature stroma with variable number strands or islands inactive-looking epithelium. presented case 46 years old male complaining asymptomatic mandibular bony swelling. Radiographically, lesion unilocular radiolucent, root resorption and displacement t...
