Diabetic cardiomyopathy (DCM) is described as impaired cardiac diastolic and systolic functions. Diabetes mellitus (DM), a related cardiovascular disease, has become one of the major causes of death in DM patients. Mortality in these diseases is 2 to 3 times higher than in non-DM patients with cardiovascular disease. The progression of DCM and the cellular and molecular perturbations associated with the pathogenesis are complex and multifactorial. Although considerable progress has been achieved, the molecular etiologies of DCM remain poorly understood...

Hydatid disease is an important economic and human public health problem with a wide geographical distribution. Surgical excision remains the primary treatment and the only hope for complete cure of hydatosis. The most important complications arising from surgical excision, however, is recurrence, which is due to dissemination of protoscolices during the surgery. Pre-surgical inactivation of the contents of the hydatid cyst by injection of scolicidal agent into the cyst has been used as adjunct to surgery in order to overcome the risk of recurrence...

Curcumin is a naturally occurring polyphenol isolated from Curcuma longa that has gained considerable interest over the last decades due to its beneficial effects for human health. Moreover, the usage of cisplatin, a platinum-based chemotherapeutic, is associated with several adverse effects affecting the quality of life of the patients. Also, cisplatin therapy is jeopardized by a great challenge of resistance which reduces the efficacy of this drug. In order to conquer these dark sides of cisplatin therapy, curcumin has been widely used to fight against cisplatin-resistant cancer cells and decrease its unwanted side effects (e...

curcumin is the main bioactive component contained in Curcuma Longa, largely employed in traditional medicine. Recently, beneficial properties, useful for prevention and treatment of several disorders, have been discovered for this compound. Peculiar structural feature is an α,β-unsaturated carbonyl system essential for establishing contacts with critical cysteine residues of several targets. This distinctive mechanism of action imparts to the molecule the ability to affect a large number of targets, accounting for its pleiotropic behaviour and definition of "privileged structure"...

Curcumin, a hydrophobic polyphenol, is the principal constituent extracted from dried rhizomes of Curcuma longa L. (turmeric). Curcumin is known as a strong anti-oxidant and anti-inflammatory agent that has different pharmacological effects. In addition, several studies have demonstrated that curcumin is safe even at dosages as high as 8g per day; however, instability at physiological pH, low solubility in water and rapid metabolism results in a low oral bioavailability of curcumin. The phytosomal formulation of curcumin (a complex of curcumin with phosphatidylcholine) has been shown to improve curcumin bioavailability...
