E-cadherin, a member of the cadherin family, plays a major role in cell-cell adhesion of normal epithelium. Recent studies have shown that reduction or loss of E-cadherin expression in carcinomas have some relationship with their clinicopathological manifestation including invasion and metastasis. In the present study, we have established cell clones with different E-cadherin expression from hu...

OBJECTIVES The bonding effectiveness of five adhesive luting agents to enamel and dentin using different application procedures was determined using a micro-tensile bond strength protocol (microTBS). METHODS Enamel/dentin surfaces of human third molars were flattened using a high-speed diamond bur. Composite resin blocks (Paradigm, 3M ESPE) were luted using either Linkmax (LM; GC), Nexus 2 (N...

Developing new types of optimized electrodes for specific biomedical applications can substantially improve the quality of the sensed signals. Concentric ring electrodes have been shown to provide enhanced spatial resolution to that of conventional disc electrodes. A sensor with different electrode sizes and configurations (monopolar, bipolar, etc.) that provides simultaneous records would be v...

We developed an ECG T-shirt with a portable recorder for unobtrusive and long-term multichannel ECG monitoring with active electrodes. A major drawback of conventional 12-lead ECGs is the use of adhesive gel electrodes, which are uncomfortable during long-term application and may even cause skin irritations and allergic reactions. Therefore, we integrated comfortable patches of conductive texti...

BACKGROUND Molecules taken up by olfactory and trigeminal nerve neurons directly access the brain by the nose-to-brain pathway. In situ-forming mucoadhesive gels would increase the residence time of intranasal material, favoring the nose-to-brain delivery. In this first approach, brain radioactivity after intranasal administration of (32)P-small interference RNA (siRNA) complexed with poly(amid...

giant cell fibroma (gcf) was described as a new entity of fibrous hyperplastic soft tissue. it seems that stimulus from an unexplained origin can have a role in its etiology. histopathologically gcf is consisted of multinucleated fibroblasts that have oval shape nuclei within the eosinophilic cytoplasm. surgical excision is the treatment of choice and recurrence is very rare. here we report a c...

The aim of this study was to develop an intranasal in situ thermo-gelling meloxicam-human serum albumin (MEL-HSA) nanoparticulate formulation applying poloxamer 407 (P407), which can be administered liquid state into the nostril, and increase resistance against mucociliary clearance by sol-gel transition on nasal mucosa, as well improve drug absorption. Nanoparticle characterization showed that...

The present paper reviews the self-aggregation, gel-forming and adsorption properties of xyloglucan (XG), its main applications as a medical device for wound dressings, mucosal protection ocular lubrication, well uses an excipient. XG is branched polysaccharide composed central backbone D-glucose units linked by ?(1?4)-glycosidic bonds, decorated with D-xylose through ?(1?6) glycosidic some D-g...

Aim : To study the features of morpho-functional changes in small intestine mucosa acute adhesive bowel obstruction. Material and methods . The results a comprehensive morphological functional intestine’s mucous membrane 20 patients out 50 with intestinal obstruction were analyzed. Patients underwent resection biopsy from membrane, followed by pathomorphological biochemical examination specimen...

Purpose. Nitrotyrosine was quantitated in rabbit bladder muscle and mucosa using two analytical systems: Western blotting analyses and a 96-well plate quantitative analysis kit. Materials and Methods. Rabbit bladder muscle and mucosa were obtained from control rabbits. For the Western analysis, the samples were loaded into a SDS page gel and then transferred to a PVDF membrane. The optical dens...
