BACKGROUND Inhaled long-acting beta2 agonists used alone and in combination with an inhaled corticosteroid reduce the risk of exacerbations in patients with stable COPD. However, the relative efficacy of these agents in preventing recurrent exacerbations in those recovering from an initial episode is not known. This study compared the rate of COPD exacerbations over the 26 weeks after an initia...

Salvianolic acid B (Sal B), a pure water-soluble compound extracted from Radix Salviae miltiorrhizae, has been reported to possess potential cardioprotective efficacy. To identify proteins or pathways by which Sal B might exert its protective activities on the cardiovascular system, two-dimensional gel electrophoresis-based comparative proteomics was performed, and proteins altered in their exp...

The aims of the present study were to clarify the effect of salsolinol (SAL), a dopamine (DA)-derived endogenous compound, on the secretion of prolactin (PRL) in cattle. The experiments were performed from April to June using calves and cows. A single intravenous (i.v.) injection of SAL (5mg/kg body weight [BW]) or sulpiride (a DA receptor antagonist, 0.1mg/kg BW) significantly stimulated the r...

The degenerative loss through apoptosis of dopaminergic neurons in the substantia nigra pars compacta plays a primary role in the progression of Parkinson's disease (PD). Our in vitro experiments suggested that salidroside (Sal) could protect against 1-methyl-4-phenylpyridine-induced cell apoptosis in part by regulating the PI3K/Akt/GSK3β pathway. The current study aims to increase our understa...

Dexamethasone (Dex) and other glucocorticoids are widely used to treat serious infections and immunological diseases, however they may cause steroid‑induced avascular necrosis of the femoral head (SANFH). Salidroside (Sal) has demonstrated an anti‑apoptotic effect on neurocytes by activating the phosphoinositide 3‑kinase (PI3K)/protein kinase B (Akt) signaling pathway. In the present study, pri...

C57BL/6 mice that had recently rejected a primary Sarcoma I (Sal) ascitic tumor were given a second i.p. dose of Sal cells. The interaction of the immune macrophages of the host and the Sal target cells was investigated by electron microscopy. The macrophages rapidly adhered to the target cells and spread over their surfaces. The interaction of the immune macrophages and Sal cells was manifeste...

Spinal cord injury (SCI) is a severe neurological disease; however, few drugs have been proved to treat SCI effectively. Neuroinflammation is the major pathogenesis of SCI secondary injury and considered to be the therapeutic target of SCI. Salidroside (Sal) has been reported to exert anti-inflammatory effects in airway, adipose and myocardial tissue; however, the role of Sal in SCI therapeutic...

In the bioethanol production process via acid saccharification, a large amount of acid hydrolysis lignin is yielded as a byproduct. In this study, the behavior of hardwood sulfuric acid lignin (SAL), which is a typical acid hydrolysis lignin, during phenolization to convert into functional materials is investigated. We compared the product yield, average molecular weight, methoxy content, and r...

Salvianolic Acid B (Sal B), an active compound extracted from the Chinese herb Salvia miltiorrhiza, is attracting more and more attention due to its biological activities, including antioxidant, anticoagulant and antitumor effects. However, autophagy induction in cancer cells by Sal B has never been recognized. In this study, we demonstrated that Sal B induced cell death and triggered autophagy...

Anti-angiogenesis targeting VEGFR2 has been an attractive strategy for cancer therapy for its role in promoting cancer growth and metastasis. However, the currently available drugs have unexpected side effects. Therefore, development of novel VEGFR2 inhibitors with less toxicity would be of great value. In this study, we describe a novel and safely VEGFR2 inhibitor, Salinomycin (Sal), which was...
