There is always a tradeoff between privacy and the desired level of security for any internet user in the contemporary cyber world. Cyber security, of late, is paramount and its breach could lead to untoward consequences, at times, disastrous. The advent of the IPv6 provides a hope to resolve this tradeoff satisfactorily. Included in the IPV6 suite is a method for devices to automatically confi...
Gastric neuroendocrine carcinoma is a rare tumor which has a poor prognosis. Herein, we present a 55-year-old woman who presented with complaints of recurrent vomiting, hematemesis and weight loss. Endoscopic examination showed a large ulcerated mass in the antrum. Microscopic evaluation of the specimen taken through biopsy was compatible with a small round cell tumor. However, definitive histo...
Chromogranin A, a soluble acidic protein, is a ubiquitous component of secretory vesicles throughout the neuroendocrine system. We reported previously the cloning and initial characterization of the mouse chromogranin A gene promoter, which showed that the promoter contains both positive and negative domains and that a proximal promoter spanning nucleotides -147 to +42 bp relative to the transc...
Histamine and chromogranin A-immunoreactive cells were studied in the mucosa of the human stomach. Cells reacting to both histamine and chromogranin A-antibodies (histamine containing endocrine cells), were demonstrated by double immunostaining and found to be restricted to the oxyntic mucosa. Histamine containing cells that did not stain with chromogranin A-antibodies were numerous throughout ...
In normal human lungs, neuroendocrine (NE) cells can be found as solitary NE cells and in corpuscular aggregates, the neuroepithelial bodies. By means of a quantitative morphometric method, we compared the number and distribution of chromogranin-reactive NE cells in anthracosilicotic and control lungs. After death, 14 pairs of control and 12 pairs of anthracosilicotic lungs were sampled. The ex...
Developing Coffea arabica seeds accumulate large amounts of chlorogenic acids (CGAs) as a storage form of phenylpropanoid derivatives, making coffee a valuable model to investigate the metabolism of these widespread plant phenolics. However, developmental and environmental regulations of CGA metabolism are poorly understood. In the present work, the expression of selected phenylpropanoid genes,...
Chromogranin A, although it exhibits limitations, is currently the most useful general tumor biomarker available for use in the diagnosis and management of gastroenteropancreatic neuroendocrine tumors (NETs). The value of the chromogranin A lies in its universal cosecretion by the majority of neuroendocrine cells that persists after malignant transformation. Clinicians aware of the physiologic ...
