Chronic enteritis can produce an excess of reactive oxygen species resulting in cellular damage. Stanniocalcin-1(STC-1) reportedly possesses anti-oxidative activity, the aim of this study was to define more clearly the direct contribution of STC-1 to anti-oxidative stress in cattle. In this study, primary intestinal epithelial cells (IECs) were exposed to hydrogen peroxide (H2O2) for different ...

PURPOSE Very few tumor molecular markers have been identified that are highly specific for breast cancer cells when applied to blood and bone marrow (BM). Stanniocalcin (STC)-1 is a recently discovered human gene that has been implicated in cellular calcium homeostasis and resistance to hypoxia and is located on chromosome 8p in a region associated with amplification in breast cancer. We invest...

Stanniocalcin (STC) decreases branchial Ca(2+)-uptake in fish. In order to determine its bioactive domain, synthetic fragments (U amino acids (aa) 1-20; V aa 103-136; W aa 202-231) of eel STC were tested for their effect on Ca2+ uptake in tilapia (Oreochromis mossambicus). Ca2+ uptake was inhibited by an N-terminal fragment but not by a midfragment nor a C-terminal fragment of the mature hormon...

Animals exposed for a few hours to low oxygen content (8%) develop resistance against further ischemic myocardial damage. The molecular mechanism(s) behind this phenomenon, known as hypoxic preconditioning (HOPC), is still incompletely understood. Stanniocalcin-1 (STC-1) is an evolutionarily conserved glycoprotein originally discovered in fish, in which it regulates calcium/phosphate homeostasi...

Stanniocalcin (STC) is a polypeptide hormone discovered first in fish and more recently in mammals. In mammals, the gene is widely expressed and the hormone is, so far, known to be involved in regulating the transport of calcium or phosphate across renal and gut epithelia, and into neuronal cells. Gene expression is also high during development, and in an earlier study we mapped the temporal an...

The occurrence of sterigmatocystin (STC) in paddy and processed rice samples produced in Italy was surveyed. After extraction and purification, STC was analysed using HPLC-MS/MS. STC was detected in all paddy rice samples (n = 49), in the range 0.29-15.85 μg·kg-1. As regards processed rice, a widespread contamination was found in brown and parboiled rice. All the brown rice samples were contami...

The release in vivo and in vitro of stanniocalcin (STC) from the corpuscles of Stannius (CS) of the rainbow trout and the European eel was studied. Intraperitoneal injection of CaCl2 (2.45 mmol.kg-1 fish) leads to an elevation of both ionic and total calcium in the plasma and results in the release of STC from the CS into the blood. Release of STC in vitro is not affected at "physiological" (1....

Assume a STC (space-time codes) OFDM (orthogonal frequency-division multiplexing) scheme the receiver antennas and multiple transmitters on compared time-chosen fading channels and frequency. It has been displayed that the time-selectivity product array is the input parameter to describe the associated fading channel outage capacity. It is considered that space-time codes with huge efficient ex...

Tachykinins are important neurotransmitters regulating intestinal motility. Slow transit constipation (STC) represents an extreme colonic dysmotility with unknown etiology that predominantly affects women. We examined whether the tachykinin system is involved in the pathogenesis of STC. Isolated sigmoid colon circular muscle from female STC and control patients was studied using functional and ...

BACKGROUND The purposes of the study were to compare serum total cortisol (STC), salivary cortisol (SaC) and calculated free cortisol (cFC) levels at baseline and after the adrenocorticotrophic hormone (ACTH) stimulation test in patients with severe sepsis (SS) and determine the suitability of use of SaC and cFC levels instead of STC for the diagnosis of adrenal insufficiency (AI) in patients w...
