Current evidence indicates that semicarbazide-sensitive amine oxidase (SSAO) substrates possess insulin-mimic effect, which was thought to play an anti-inflammatory role. The purpose of the present study was to determine whether SSAO substrates benzylamine (BZA) and methylamine (MA) attenuate inflammatory response induced by lipopolysaccharide (LPS). BALB/c(More)
BACKGROUND Copper is a strong pro-oxidant. The most important pro-oxidative form in serum is small molecule copper (SMC), which is copper that is loosely bound to small molecules, such as amino acids and polypeptides. The association between copper and atherosclerotic diseases has been confirmed, but that between SMC and cerebral ischemic stroke (CIS), one(More)
Significant changes of copper homeostasis were triggered by lipopolysaccharides, which result in systemic inflammatory response and contribute to hepatic injury. Administration of lipopolysaccharides resulted in the increase of plasma “free” copper and total copper concentrations, whereas, the decrease of “free” copper and total copper contents in liver(More)
Angiogenesis has become an attractive target for cancer therapy since the US Food and Drug Administration (FDA) approved the first angiogenesis inhibitor (bevacizumab) for the treatment of metastatic colorectal cancer in 2004. In following years, a large number of angiogenesis inhibitors have been discovered and developed, ranging from monoclonal(More)
Semicarbazide-sensitive amine oxidase (SSAO) is present in plasma, as well as in other tissues. Previous studies indicated that SSAO is of important physiological and pathophysiological functions. HPLC methods were developed for the assay of SSAO in plasma, and for the determination of plasma methylamine, an SSAO's endogenous substrate. Benzylamine was used(More)
Hydralazine (HYD), an old routine clinical anti-hypertension drug, is rarely used in clinic nowadays. Since the strategy of repositioning old drugs was put forward, HYD has been reported to possess various biological activities, including antitumor efficacy and reducing intra-tumor microvessel. Here, we investigated that whether HYD had the ability of(More)
Previous studies have demonstrated endogenous formaldehyde (FA) may be involved in endothelial damage, and may be a potential factor of vulnerability of atherosclerosis. However, the mechanism has not been characterized. The present studies examined DNA-protein cross-links (DPC) formation in rat aorta endothelial cells (RAECs) treated with formaldehyde,(More)
Methotrexate (MTX) has been widely used at low dose for the treatment of different diseases including rheumatoid arthritis. MTX might be present in plasma in free form, and in blood cells in methotrexate polyglutamate (MTXPG). A rapid and sensitive HPLC method was developed for the determination of plasma MTX level, whole-blood MTX level, and whole-blood(More)
BACKGROUND This study done was to investigate the clinical significance of soluble vascular adhesion protein-1 (sVAP-1) activity in trauma patients with different patterns. METHODS 96 patients with consecutive trauma ≥15 years who were admitted to emergency department of the Second Affiliated Hospital, Shantou University Medical College, China, between(More)
BACKGROUND The determination of copper (Cu) in human blood is important in medical diagnosis. However, its biological activities strongly depend on the chemical forms, and thus data for total Cu concentration is not sufficient for medical diagnosis or mechanism study. Therefore, analyses of copper species in serum have much more physiologically meaningful.(More)
