Acute vascular and metabolic actions of the green tea polyphenol epigallocatechin 3-gallate in rat skeletal muscle.

Epidemiological studies show a dose-dependent relationship between green tea consumption and reduced risk for type 2 diabetes and cardiovascular disease. Bioactive compounds in green tea including the polyphenol epigallocatechin 3-gallate (EGCG) have insulin-mimetic actions on glucose metabolism and vascular function in isolated cell culture studies. The aim of this study is to explore acute vascular and metabolic actions of EGCG in skeletal muscle of Sprague-Dawley rats.

Drug delivery system targeting advanced hepatocellular carcinoma: Current and future.

Unlabelled: Hepatocellular carcinoma (HCC) has a fairly high morbidity and is notoriously difficult to treat due to long latent period before detection, multidrug resistance and severe drug-related adverse effects from chemotherapy. Targeted drug delivery systems (DDS) that can selectively deliver therapeutic drugs into tumor sites have demonstrated a great potential in cancer treatment, which could be utilized to resolve the limitations of conventional chemotherapy. Numerous preclinical studies of DDS have been published, but targeted DDS for HCC has yet to be made for practical clinical use.

Exploring Different Strategies for Efficient Delivery of Colorectal Cancer Therapy.

Colorectal cancer (CRC) is the third most common cancer and the fourth leading cause of cancer death in the world. Currently available chemotherapy of CRC usually delivers the drug to both normal as well as cancerous tissues, thus leading to numerous undesirable effects. Much emphasis is being laid on the development of effective drug delivery systems for achieving selective delivery of the active moiety at the anticipated site of action with minimized unwanted side effects.

The potential of liposomes with carbonic anhydrase IX to deliver anticancer ingredients to cancer cells in vivo.

Drug delivery nanocarriers, especially targeted drug delivery by liposomes are emerging as a class of therapeutics for cancer. Early research results suggest that liposomal therapeutics enhanced efficacy, while simultaneously reducing side effects, owing to properties such as more targeted localization in tumors and active cellular uptake. Here, we highlight the features of immunoliposomes that distinguish them from previous anticancer therapies, and describe how these features provide the potential for therapeutic effects that are not achievable with other modalities.

Vascular and metabolic actions of the green tea polyphenol epigallocatechin gallate.

Epidemiological studies demonstrate robust correlations between green tea consumption and reduced risk of type 2 diabetes and its cardiovascular complications. However, underlying molecular, cellular, and physiological mechanisms remain incompletely understood. Health promoting actions of green tea are often attributed to epigallocatechin gallate (EGCG), the most abundant polyphenol in green tea.

Muscle insulin resistance resulting from impaired microvascular insulin sensitivity in Sprague Dawley rats.

Aims: Enhanced microvascular perfusion of skeletal muscle is important for nutrient exchange and contributes ∼40% insulin-mediated muscle glucose disposal. High fat-fed (36% fat wt./wt.
