The large dense-core secretory granule is an organelle in neuroendocrine/endocrine cells, where prohormones and proneuropeptides are stored, processed, and secreted in a regulated manner. Here we present evidence that chromogranin A (CgA), one of the most abundant acidic glycoproteins ubiquitously present in neuroendocrine/endocrine cells, regulates dense-core secretory granule biogenesis. Spec...

PURPOSE We investigated the clinical significance of chromogranin A (CgA) expression as a neuroendocrine (NE) marker during prostate cancer (PCa) progression, especially as a potential predictor of chemotherapeutic response in castration-resistant PCa (CRPC) patients based on immunohistochemical findings. MATERIALS AND METHODS Sixteen CRPC patients who underwent combination (docetaxel/estramu...

OBJECTIVE To examine the effects of chlorogenic acid (CGA) on lipid and glucose metabolism under a high dietary fat burden and to explore the possible role of peroxisome proliferator-activated receptor-alpha (PPAR-alpha) in these effects. METHODS Twenty male golden hamsters were randomly divided into CGA treatment group (n=10, given peritoneal injection of CGA solution prepared with PBS, 80 m...

Cryptographically Generated Addresses (CGA) are today mainly used with the Secure Neighbor Discovery Protocol (SEND). Despite CGA generalization, current standards only show how to construct CGA with the RSA algorithm and SHA-1 hash function. This limitation may prevent new usages of CGA and SEND in mobile environments where nodes are energy and storage limited. In this paper, we present the re...

OBJECTIVE Chromogranin A (CGA) levels are used to confirm the diagnosis and monitor the course of patients with neuroendocrine tumors. Chromogranin A levels are significantly reduced when patients are acutely treated with octreotide; however, limited data are available that correlates octreotide long-acting repeatable (LAR) dose or steady state octreotide blood levels to the absolute value of s...

INTRODUCTION Chromogranin A (CgA) is a major, nonspecific marker of neuroendocrine tumours (NET). There are a few routinely used assays for the measurement of CgA concentration in serum or plasma. These assays differ in analytical techniques (radioimmunoassay, ELISA, CLIA, TRACE), have different calibrators, and use different antibodies which recognise different epitopes of CgA molecule. Our st...

The primary aim of the present study was to determine the prognostic role of elevated levels of chromogranin A (CgA) in terms of biochemical prostate-specific antigen (PSA) progression after radical prostatectomy (RRP) for prostate adenocarcinoma. Two hundred and sixty-four consecutive men with non-metastatic prostate adenocarcinoma submitted to RRP represented our population. In all cases, a b...

An improved strategy for finding the ab initio global minimum of SixHy clusters based on a cluster genetic algorithm (CGA) is presented. Four new mutation operators are introduced which better facilitate retention of desirable structural features between the different generations of clusters in the CGA. The new CGA generally finds global minima with fewer energy evaluations and is now able to f...

Quality control systems monitor and stop translation at some ribosomal stalls, but it is unknown if halting translation at such stalls actually prevents synthesis of abnormal polypeptides. In yeast, ribosome stalling occurs at Arg CGA codon repeats, with even two consecutive CGA codons able to reduce translation by up to 50%. The conserved eukaryotic Asc1 protein limits translation through inte...

The need for nodes to be able to generate their own address and verify those from others, without relying on a global trusted authority, is a well-known problem in networking. One popular technique for solving this problem is to use self-certifying addresses that are widely used and standardized; a prime example is cryptographically generated addresses (CGA). We re-investigate the attack models...
