BACKGROUND Rhodiola crenulata is traditionally used as a folk medicine in Tibet for preventing high-altitude illnesses, including sudden cardiac death (SCD). The cardio-protective effects of Rhodiola crenulata root extract (RCE) against hypoxia in vivo have been recently confirmed. However, the way

Effects of Salidroside on cobalt chloride-induced hypoxia damage and mTOR signaling repression in PC12 cells.

Only registered users can translate articles

Salidroside (SA), a phenylpropanoid glycoside isolated from Rhodiola rosea L., has been documented to exert a broad spectrum of pharmacological properties, including protective effects against neuronal death induced by various stresses. To provide further insights into the neuroprotective functions

Effects of Modulation of Ion Channel Currents by Salidroside in H9C2 Myocardial Cells in Hypoxia and Reoxygenation.

Only registered users can translate articles

Salidroside, a phenyl-propanoid glycoside isolated from the medicinal plant Rhodiola rosea, has potent cardioprotective effects, especially against myocardial hypoxia and reoxygenation injury. However, the molecular mechanism underlying its action is still unclear. The aim of this study was

The Protective Effect of Salidroside on Hypoxia-Induced Corpus Cavernosum Smooth Muscle Cell Phenotypic Transformation.

Only registered users can translate articles

Salidroside, a major active ingredient isolated from Rhodiola rosea, has a long application in Chinese medical history. It has widely demonstrated effects on fatigue, psychological stress, and depression and exhibits potential antihypoxia activity. Emerging evidence shows that hypoxia is an

Mechanism of action of Rhodiola imbricata Edgew during exposure to cold, hypoxia and restraint (C-H-R) stress induced hypothermia and post stress recovery in rats.

Only registered users can translate articles

Mechanism of rhodiola root extract adaptogenic activity was studied in rats. The extract was orally administered in rats (100mg/kg body weight), 30 min prior to cold (5 degrees C)-hypoxia (428 mmHg)-restraint (C-H-R) exposure up to fall of T(rec)23 degrees C and recovery (T(rec)37 degrees C) from

Trans-Himalayan Phytococktail Confers Protection Against Hypobaric Hypoxia-Induced Hippocampal Neurodegeneration and Memory Impairment in Male Sprague Dawley Rats.

Only registered users can translate articles

Background: Exposure to hypobaric hypoxia (HH) has been reported to cause neurodegeneration and memory impairment. Hippophae rhamnoides, Prunus armeniaca, and Rhodiola imbricata, the indigenous plants of Indian Trans-Himalaya are widely used in traditional Tibetan and

Rhodiola crenulata and Its Bioactive Components, Salidroside and Tyrosol, Reverse the Hypoxia-Induced Reduction of Plasma-Membrane-Associated Na,K-ATPase Expression via Inhibition of ROS-AMPK-PKC ξ Pathway.

Exposure to hypoxia leads to impaired pulmonary sodium transport, which is associated with Na,K-ATPase dysfunction in the alveolar epithelium. The present study is designed to examine the effect and mechanism of Rhodiola crenulata extract (RCE) and its bioactive components on hypoxia-mediated

Bioactive fraction of Rhodiola algida against chronic hypoxia-induced pulmonary arterial hypertension and its anti-proliferation mechanism in rats.

Only registered users can translate articles

BACKGROUND Rhodiola algida var. tangutica (Maxim.) S.H. Fu is a perennial plant of the Crassulaceae family that grows in the mountainous regions of Asia. The rhizome and roots of this plant have been long used as Tibetan folk medicine for preventing high latitude sickness. OBJECTIVE The aim of this

Comparative Study on the Protective Effects of Salidroside and Hypoxic Preconditioning for Attenuating Anoxia-Induced Apoptosis in Pheochromocytoma (PC12) Cells.

Only registered users can translate articles

BACKGROUND Hypoxia is an important sign that can result from body injuries or a special condition such as being at a high altitude or deep water diving. In the current studies, hypoxic preconditioning (HPC) plays a key role in reducing hypoxia-induced apoptosis. We aimed to study the pharmacologic

Salidroside mitigates hypoxia/reoxygenation injury by alleviating endoplasmic reticulum stress‑induced apoptosis in H9c2 cardiomyocytes.

Only registered users can translate articles

Endoplasmic reticulum (ER) stress‑induced apoptosis serves a crucial role in the development of myocardial ischemia/reperfusion (I/R) injury. Salidroside is a phenylpropanoid glycoside isolated from Rhodiola rosea L., which is a plant often used in traditional Chinese medicine. It possesses multiple

Enhancing the chemotherapy effect of Apatinib on gastric cancer by co-treating with salidroside to reprogram the tumor hypoxia micro-environment and induce cell apoptosis.

Only registered users can translate articles

Hypoxic microenvironment commonly occurred in the solid tumors considerably decreases the chemosensitivity of cancer cells. Salidroside (Sal), the main active ingredient of Rhodiola rosea, was shown to be able of regulating the tumor hypoxia micro-environment and enhancing the

Lack of effect of Rhodiola or oxygenated water supplementation on hypoxemia and oxidative stress.

Only registered users can translate articles

OBJECTIVE This study investigated the effects of 2 potentially "oxygen promoting" dietary supplements on hypoxia and oxidative stress at a simulated altitude of 4600 m. METHODS Fifteen volunteers (ages 20-33) received 3 separate 60-minute hypoxic exposures by breathing 13.6% oxygen at an ambient

MicroRNA-21 mediates the protective effects of salidroside against hypoxia/reoxygenation-induced myocardial oxidative stress and inflammatory response.

Only registered users can translate articles

Myocardial ischemia-reperfusion (I/R) injury is the oxidative stress and inflammatory response that occurs when a tissue is reperfused following a prolonged period of ischemic injury. Growing evidence has demonstrated that microRNAs (miRs) are essential in the development of myocardial I/R injury.

Anti-oxidative effect of Rhodiola imbricata root extract in rats during cold, hypoxia and restraint (C-H-R) exposure and post-stress recovery.

Only registered users can translate articles

Anti-oxidative potential of Rhodiola imbricata root aqueous extract was examined in rats, administered orally at a dose of 100 mg/kg both in single and multiple doses, 30 min prior to cold (5 degrees C)-hypoxia (428 mmHg)-restraint (C-H-R) exposure. Lipid per-oxidation, anti-oxidant parameters and

Protective Effects of Rhodiola Crenulata Extract on Hypoxia-Induced Endothelial Damage via Regulation of AMPK and ERK Pathways.

Only registered users can translate articles

Rhodiola crenulata root extract (RCE) has been shown to possess protective activities against hypoxia both in vitro and in vivo. However, the effects of RCE on response to hypoxia in the endothelium remain unclear. In this study, we aimed to examine the effects of RCE in endothelial cells challenged
