The introduction of nucleic acids into cells has as a purpose of medical condition or disease. Currently, gene therapy studies a broad range of potential therapeutic interventions, including the body’s immune reaction to tumours, new blood vessels in the heart to alleviate heart attacks and to stop HIV-replication in patients with AIDS1 .There is also renewed emphasis on the gene therapy of genetic diseases, such as haemophilia A and B, and cystic fibrosis. Human gene therapy experimentation raises many issues. In this review article, background of gene therapy, introduction, genetic diseases, gene function, germ line gene therapy, hurdles in gene therapy, methods for gene therapy, ex vivo, in vitro and in vivo-gene therapy, risks associated with gene therapy, have been...

Niosomes are non-ionic surfactant vesicles inclosing an aqueous phase and a wide range of molecules could be encapsulated within aqueous spaces of lipid membrane vesicles. They are microscopic lamellar structures formed on the admixture of a non-ionic surfactant, cholesterol and phosphate with subsequent hydration in aqueous media. Niosomes belongs to novel drug delivery system which offers a large number of advantages over other conventional and vesicular delivery systems. Namely they are the targeted drug delivery system which showing reduction of dose, stability and compatibility of non-ionic surfactants, easy modification, delayed clearance, suitability for a wide range of Active Pharmaceutical...

Some plants are toxic to living beings including humans, and are widely used all over the world in the treatment of various types of body ailments in traditional medicine, especially in the developing countries, due to theirs economic, social and cultural conditions. These plants are routinely taken for the nourishment of the pregnant women. This may cause the toxicity to the developing foetus, known as teratogenicity effect, and the plants are qualified as teratogens. Fenugreek is one of these plants, which has a wide range of medical applications, and wide use by ladies during pregnancy for different reasons. This Paper aims to present an overview of some existing studies and status of the teratogenic effect of fenugreek, to benefit from their results and...

Hypertension is a chronic increase in blood pressure, characterized as primary and secondary hypertension. The disorder is associated with various risk factors like obesity, diabetes, age, lack of exercise etc. Hypertension is being treated since ancient times by Ayurvedic, Chinese and Unani medicine. Now various allopathic drugs are available which include diuretics, calcium channel blockers, α-blockers, β-blockers, vasodilators, central sympatholytics and ACE-inhibitors. Non-pharmacological treatments include weight reduction, dietary sodium reduction, increased potassium intake and reduction in alcohol consumption. ACE-inhibitors are widely used in the treatment of hypertension by inhibiting the angiotensin converting enzyme responsible for the conversion of angiotensin I to angiotensin II (responsible for vasoconstriction). Various structure activity relationship studies led to the synthesis of ACE-inhibitors, some are under clinical development. This comprehensive review gives various guidelines on classification of hypertension, hypertension therapy including ancient, pharmacological, non-pharmacological therapies, pharmacoeconomics, historical perspectives of ACE, renin, renin angiotensin system (circulating vs local RAS), mechanism of ACE inhibitors, and development of ACE inhibitors. Review also emphasizes on the recent advancements on...

Natural steroids, the simple mention of the word brings up topics like cheating, unfair advantages. The first misconception is that all steroids are used for muscle building. This is not at all the case, steroids are natural substances with many different effects in the human body, which begin over several days, as even birth control pills are a form of steroids. “Natural Steroids”, are the organic compounds which are not chemically altered, that mimics hormones, and obviously the hormone it mimics is testosterone. Natural Steroids are involved in a wide range of physiologic processes, including stress response, immune response, carbohydrate metabolism, protein catabolism, blood electrolyte levels, and in the regulation of inflammation, and behavior. The uses are far outreach simply bulking up on muscle. Natural steroids can be used to increase certain enzymes a person’s body may have trouble creating naturally, such as testosterone, which is vital in the development in growing...
