Mechanisms of Insulin Action
More than 18 million people in the United States have diabetes mellitus, and about 90% of these have the type 2 form of the disease. In addition, between 17 and 40 million people have insulin resistance, impaired glucose tolerance, or the cluster of abnormalities referred to variably as the metabolic syndrome, the dysmetabolic syndrome, syndrome X, or the insulin resistance syndrome. In all of these disorders, a central component of the pathophysiology is insulin resistance, i.e., reduced responsiveness to insulin in tissues such as muscle, fat and liver. Insulin resistance is also closely linked to other common health problems, including obesity, polycystic ovarian disease, hyperlipidemia, hypertension, and atherosclerosis. In this book, we will attempt to dissect the complexity of the molecular mechanisms of insulin action with a special emphasis on those features of the system that are subject to alteration in type 2 diabetes and other insulin resistant states. We explore insulin action at the most basic levels, through complex systems. The book will be appealing to basic and clinical scientists.
Hyperlipidemia Management for Primary Care : An Evidence-Based Approach
Hyperlipidemia Management for Primary Care: An Evidence-Based Approach is a comprehensive resource for primary care providers that offers information and treatment options that can be incorporated with ease into everyday clinical practice. This evidence-based text weighs the benefits of pharmacologic treatments, popular diets, therapeutic foods, herbs and vitamins as a means to manage hyperlipidemia.
Human battle against obesity
Obesity is one of the most common preventable diseases and it is a medical condition in which excess fat has accumulated in the body, mostly in the subcutaneous tissues. Clinical obesity is considered to be present when a person has a body mass index of 30 or over. Obesity results from a chronic positive energy balance regulated by a complex interaction between endocrine tissues and the central nervous system, This activity reviews the pathophysiology of obesity, inflammatory markers secreted by excessive fat deposition in adipose tissue, and their effects on chronic diseases such as hypertension, diabetes, and dyslipidemia.
Enhancing the Dissolution Rate of Atorvastatin by Solid Dispersion Technique
In the last few decades, solid dispersion (SD) technology had been studied as an approach to produce an amorphous carrier to enhance the solubility, dissolution rate, and bioavailability of poorly water-soluble drugs. The use of suitable carrier and methodology in the preparation of SDs play a significant role in the biological behavior of the SDs. Atorvastatin is a statin group HMG-CoA reductase inhibitor drug that is commonly used to adverse cardiovascular events and to lower blood total cholesterol and LDL-cholesterol. the solubility of atorvastatin in water is very low (0.1 mg mL− 1), which results in reduced bioavailability. In order to enhance its solubility, we have prepared solid dispersions (SDs) of atorvastatin at different drug: polymer ratios (1:2, 1:10, 1:20,1:25 and 1:40), using polyethylene glycol 6000 as polymer and different preparation methods (co-precipitate and melting methods) The characterization of the SDs was performed using differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR) The solubility of AT was improved by the incorporation PEG6000.

Updated drug information reflects the most current, clinically relevant pharmacology material. Approachable outline format distills complex information for easier review. High-quality illustrations reinforce understanding in vibrant detail. Enhanced review questions with answers test students' understanding and identify areas for further study.
Axon growth and guidance
The complexarchitectureofneuronal networks togetherwith the extraordinary associated functions make the nervous system a fascinating biological structure. The considerable work performed to explore this cellular machinery is nowadays successfulbecause the mysteryofnervous system developmentisbeing unravelled. As described in their outstanding review published 10 years ago in Science.' Marc Tessier-Lavigne and Corey Goodman-the pioneers of the molecular era of axon guidance-summarized the assembly of nervous system connections as a subtle game of attraction and repulsion of neuronal growth cones. The cellular ballet ensuring the formation of billions of synapses, which ultimately gives rise to the highest cognitive functions, is primarily orchestrated by a step-by-step mechanism of growth driven by multiple molecular cues. While our general concept of axon guidance remains identical, a profound evolution ofour knowledge ofthe molecular identityofthe guidance cues together with their interactions and signalling pathways occurred over the past ten years.
Antidiabetic plants for drug discovery pharmacology, secondary metabolite profiling, and ingredients with insulin mimetic activity
Takes an in-depth look at the potential pharmacological applications of 11 important antidiabetic plants, examining their antihyperglycemic, hypoglycemic, and anti-lipidemic properties along with current genome editing research perspectives. Plant natural products, or phytoconstituents, are promising candidates for antidiabetic pharmacological actions. The phytoconstituents, such as fl avonoids, terpenoids, saponins, carotenoids, alkaloids and glycosides, play vital roles in the current and future potent antidiabetic drug development programs. Each chapter reviews a particular plant with antidiabetic properties, explaining the therapeutic aspects, its active antidiabetic compounds, and relevant genome editing technology.
