Properties and Applications of Ruthenium By Anil K. Sahu, Deepak K. Dash, Koushlesh Mishra, Saraswati P.
Mishra, Rajni Yadav and Pankaj Kashyap
Ruthenium (Ru) with atomic number of 44 is one of the platinum group metals, the others being Rh, Pd, Os, Ir and Pt. In earth’s crust, it is quite rare, found in parts per billion quantities, in ores containing some of the other platinum group metals. Ruthenium is silvery whitish, lustrous hard metal with a shiny surface. It has seven stable isotopes. Recently, coordination and organometallic chemistry of Ru has shown remarkable growth. In this chapter, we review the application of Ru in diverse fields along with its physical and chemical properties. In the applications part of Ru we have primarily focused on the biomedical applications. The biomedical applications are broadly divided into diagnostic and treatment aspects. Ru and their complexes are mainly used in determination of ferritin, calcitonin and cyclosporine and folate level in human body for diagnosis of diseases. Treatment aspects focuses on immunosuppressant, antimicrobial and anticancer activity.

Transethosomes and Nanoethosomes: Recent Approach on Transdermal Drug Delivery System By Koushlesh Kumar Mishra, Chanchal Deep Kaur, Shekhar Verma, Anil
Kumar Sahu, Deepak Kumar Dash, Pankaj Kashyap and Saraswati
Prasad Mishra
In the past few decades, an emerging drug delivery system that came into light is transdermal drug delivery system. It has become the talk of the town in the field of drug delivery because of its better and easy accessibility. Though it is one of the attractive routes, transport of drug through the skin has remained a challenge. To overcome the challenge, vesicular system has been adopted so as to have better skin permeation of bioactive agents. Vesicular system like liposome has shown inefficiency to cross the layers of skin. Then transethosomes and nanoethosomes are employed for delivering drug into the deeper layer of skin. Nanoethosomes and transethosomes have same composition that is water, ethanol and phospholipid. Transethosome contains edge activator additionally. Due to the presence of ethanol and edge activator, it displayed enhanced skin permeation. Vesicular system gives a better patient compliance, being a non-invasive method of drug administration. In this chapter, we attempted to provide brief information about methods of preparation, characterization and pharmaceutical uses of nanoethosomes and transethosomes.

Medicinal Plants Having Antifungal Properties By Koushlesh Kumar Mishra, Chanchal Deep Kaur, Anil Kumar Sahu, Rajnikant Panik, Pankaj Kashyap, Saraswati Prasad Mishra and Shweta Dutta
In the past few decades, a worldwide increase in the incidence of fungal infections has been observed as well as rise in the resistance of some species of fungi to different fungicidal used in medicinal practice. Besides, fungi are the one of the most neglected pathogens as demonstrated by the fact that the amphotericin B and other sold treatments are still used as gold standard as antifungal therapy. The majority of used antifungal treatments have various drawbacks in terms of toxicity, efficacy as well as cost and their frequent use has also led to the emergence of resistant strains. Hence, there is a great demand for developing an antifungal belonging to a wide range of structural classes, selectively acting on new targets with least side effects. Natural products, either as pure phytocompounds or as standardized plant extracts, provide unlimited opportunities for new drug lads because of their having normally matchless chemical diversity. Present chapter focused on the work done in the field of antifungal activities of various plant components and novel approaches which will be the future prospective for the new drug discoveries and providing better antifungal therapy.

Theranostics: New Era in Nuclear Medicine and Radiopharmaceuticals By Chanchal Deep Kaur, Koushlesh Kumar Mishra, Anil Sahu, Rajnikant Panik, Pankaj Kashyap, Saraswati Prasad Mishra and Anand Kumar
Malignancy and many inflammatory diseases have become a major concern for mankind over the years. The conventional therapy of these diseases lacks the effectiveness of the better diagnosis and targeted treatment of these diseases, but nuclear medicine can be regarded as a savior in the current scenario. Over the years, radioactivity of radioisotopes has been employed for treatment of many diseases. Nuclear medicines came up with radiopharmaceuticals that impart the ability to destroy specific diseased cells with high-energy-emitting radionuclides. Moreover, the emergence of theranostics, which is a combination of single drug used both for diagnostic as well as therapeutic purpose, has added a new feather in the field of nuclear medicines for providing a specific and personalized treatment to the patient. The current chapter discusses about techniques used for imaging of these radionuclides for better therapy and diagnosis of the root cause of the concerned disease by positron emission tomography (PET)/CT and single photon emission computed tomography (SPECT)/CT as well as the advantages and disadvantages associated with them. It also describes about applications of theranostics and nuclear imaging in cancer treatment and their future perspective.

Role of Nanobiotechnology in Drug Discovery, Development and Molecular Diagnostic By Deepak Kumar Dash, Rajni Kant Panik, Anil Kumar Sahu and Vaibhav Tripathi
Nano-biotechnology has already tested its magnitude in a number of sections of existence science and biotechnology field. It is no longer hyperbole to say that in future, nano-scale method would in reality take the associated science area to the subsequent level. Since, there are technical hurdles present; despite the fact that scientists are giving their great to overcome such problems. Applications of nano-biotechnology have already been discussed in this chapter. Future potential are really associated with innovative amendment of such applications. Despite of some impedance, this technology presents giant hope in the future. It performs most important position in distinct sorts of biomedical application such as shipping of drug, gene therapy, biosensors, biomarkers and molecular imaging. It additionally leads to innovations in this field. The fundamental lookup goal of this discipline would be the innovation of early analysis approach and cure with target-specific remedy therapy. Although there would possibly be some safety worries with admire to the in vivo use of nanoparticles, research are in region to decide the nature and extent of adverse events.

Risk-Benefit Events Associated with the Use of Aspirin for Primary Prevention of Cardiovascular Disorders By Deepak Kumar Dash, Vishal Jain, Anil Kumar Sahu, Rajnikant Panik and Vaibhav Tripathi
Aspirin had been introduced as a nonsteroidal anti-inflammatory molecule. As further research on aspirin started, other therapeutic effects have been revealed. Now, this molecule has become the polychrest in medical science. Aspirin has served as a drug of choice for the primary prevention of cardiovascular disease (CVD) for the last few decades. However, recent trials have raised questions on the use of aspirin for CVD prevention due to some life-threatening adverse drug events. In spite of that, outcomes of trials will surely assist to frame a guideline for anoxic administration regimen of aspirin in order to prevent CVD.

Nowadays, plant-based chemicals have drawn the attention of pharmacy researchers due to their potent biological activity against various ailments. In this series, terpenes and terpenoids are gaining popularity among drug researchers gradually. Terpenes are naturally occurring large and varied class of hydrocarbons substances produced by a wide variety of plants including fruits, vegetables, flowers and some animals. Their concentration is generally high in plants. A broad range of the biological properties of terpenoids includes cancer chemo-preventive effects, antimicrobial, antifungal, antiviral, anti-hyperglycemic, anti-inflammatory, anti-parasitic activities and memory enhancers. Terpenoids are usually cyclic unsaturated hydrocarbons, with the altered number of oxygen moieties in the constituent groups attached to the basic isoprene skeleton. Terpenoids are a group of substances that occur in nearly every natural food. Terpenoids display a wide range of biological activities against cancer, malaria, inflammation, tuberculosis and a variety of infectious diseases including viral as well as bacterial. In this chapter, we have emphasized the proven and expected medicinal value of both terpenes and terpenoids.
