allium tripedale/hypoxia

Hypoxia frequently occurs under several different cellular circumstances. Excess reactive oxygen species that are induced by hypoxia may result in cell injury and dysfunction. Recently, garlic has been found to possess some biological and pharmacological activities. The present study examined the

BACKGROUND Aged garlic extract (AGE) and its main constituent S-allylcysteine (SAC) are natural antioxidants with protective effects against cerebral ischemia or cancer, events that involve hypoxia stress. Cobalt chloride (CoCl2) has been used to mimic hypoxic conditions through the stabilization of

Exposure to hypoxia results in vasoconstriction of the pulmonary vasculature (HPV) leading to pulmonary hypertension (HPH) and reductions in blood oxygen saturation and exercise performance. Alleviation of HPV and HPH via vasodilators has been shown to improve blood oxygen saturation and exercise

The present study investigated the effect of garlic (G) on serum, liver, renal and cerebral parameters of rats with chronic intermittent hypoxia (CIH) combined with diabetes mellitus (DM). A total of 32 rats were divided into eight groups, with 4 rats/group. A total of three models were established,

The antihypoxic activity of Allium sativum clove (garlic) aqueous and methanolic extracts was studied in mice. The extracts of garlic showed that the antihypoxic effect was dose-dependent. The minimum effective doses of aqueous and methanolic extracts were 0.2 g/kg and 5.12 g/kg, respectively.

Despite its important role as a medicinal plant, some studies reported a toxic effect for garlic (Allium sativum) when given in higher doses. Herein, we investigated the possible cardiotoxic effects of high doses of S-methylcysteine (SMC), a water soluble organosulfur compound present in garlic.

Allicin (2-propene-1-sulfinothioic acid S-2-propenyl ester, diallyl thiosulfinate) is the main biologically active ingredient in garlic. The present study investigated the protective effect of allicin against cardiomyocyte apoptosis that was induced by ischemia in vitro and the potential molecular

BACKGROUND Garlic has lost its ability to form seeds in the course of its domestication. Therefore, the germplasm storage via cryopreservation is increasingly applied. The progression of the various steps within the cryopreservation procedure is accompanied by declining survival rates of the

Background/aims: The hypoxic microenvironment in NSCLC has been widely accepted as a contributor to both therapeutic resistance and tumor progression. In this study, we have explored Allicin, a key organosulfur compound present in garlic

BACKGROUND Although there is growing awareness of the beneficial potential of onion intake to lower the risk of cardiovascular disease, there is little information about the effect of onion on ischemic heart injury, one of the most common cardiovascular diseases. OBJECTIVE This study investigates

Hypoxia in the setting of liver disease is often multifactorial. Obstructive or restrictive lung disease, pleural effusions, and tense ascites are common underlying disorders. Less often observed and frequently unrecognized is hypoxia related to diffuse intrapulmonary shunting--the hepatopulmonary

BACKGROUND Preclinical and epidemiologic studies suggest that garlic intake is inversely associated with the progression of cancer and cardiovascular disease. OBJECTIVE We designed a study to probe the mechanisms of garlic action in humans. METHODS We conducted a randomized crossover feeding trial

1. Numerous compounds and changes in physical state functions shift the membrane potential of vascular smooth muscle to more negative values. The consequence is a vasodilatation because Ca2+ channels are closed. K+ channel opening frequently causes the hyperpolarization. 2. Acidification of the

Intratumoral hypoxia promotes the distant metastasis of cancer subclones. The clinical expression level of hypoxia-inducible factor-1α (HIF-1α) reflects the prognosis of a variety of cancers, especially breast cancer. Histone deacetylase (HDAC) inhibitors can target HIF-1α protein due to von

Allicin, diallyl disulfide-oxide, an active ingredient released from garlic is a systemic vasodilator that acts by an unknown mechanism. In the present experiments, pulmonary vascular responses to allicin (0.1-1.0 mg) were studied in the intact-chest anesthetized cat and in the isolated lung of the
