To investigate the early changes in protein function that induce micro-metastasis in early-stage non-small cell lung cancer, we conducted proteomic analysis of tissue that had been completely resected. We selected sixteen patients whose tumors were pathological stage I adenocarcinoma with hobnail cell morphology. We compared their proteomic profiles between patients whose cancers recurred and d...

a 29- year old female with bone pain and history of precocious puberty was referred for bone scintigraphy. on physical examination café au lait macular spots were noted on her neck, buttocks and left leg. bone scan showed multiple areas of intense increased activity which was in favour of polyostotic fibrous dysplasia. considering the presence of polyostotic fibrous dysplasia, precocious pubert...

Chlorhexidine is a chlorinated phenolic disinfectant used commonly in mouthwash for its action against bacteria. However, a comparative study of the action of chlorhexidine on the cell morphology of gram-positive and gram-negative bacteria is lacking. In this study, the actions of chlorhexidine on the cell morphology were identified with the aids of electron microscopy. After exposure to chlorh...

We used a 2-DE proteomic approach to identify abundant proteins linked to oocyte quality in the Pacific oyster Crassostrea gigas, an economically important bivalve. Oocyte quality of 14 females was estimated by recording fertilisation and early developmental success until D-larval stage under controlled conditions. Proteins that were differentially expressed between females showing high or low ...

Membrane proteins are involved in many functions due to their cellular locations. Although the effect of drought on plants has been extensively studied, little is known about the changes of membrane proteome in plants under drought conditions. We used gel-based proteomics to study the effect of drought on membrane protein expression in maize (Zea mays L.) plants. Moderate drought stress was app...

Rifaximin is a semi-synthetic rifamycin derivative that is used to treat different conditions including bacterial diarrhea and hepatic encephalopathy. Rifaximin is of particular interest because it is poorly adsorbed in the intestines and has minimal effect on colonic microflora. We previously demonstrated that rifaximin affected epithelial cell physiology by altering infectivity by enteric pat...

BACKGROUND/AIMS The primary pathophysiologic abnormality in achalasia is known to be a loss of inhibitory myenteric ganglion cells, which may result from an immune-mediated response or neuronal degeneration. The aim of this study was to identify proteins suggestive of an immune-mediated response or neuronal degeneration in the serum of achalasia patients using a proteomic analysis. METHODS Bl...

Background: Basal Cell Carcinoma (BCC) is a type of non-melanoma skin cancer. Alteration in gene expression is the important event that happens in cancer cell. Detection of this event is possible by proteomics techniques. Methods: Normal and tumor tissues were taken from BCC patient. Total proteins were purified by standard methods, and proteins were separated by two-dimensional electrophoresis...
