Abstract:
Dendrimers are perfect monodisperse macromolecules(poloymers) with regular and highly branched 3-D structure. Dendrimers have often been referred to as the “Polymer of the 21st century. They are characterized by branch upon branch architecture which are completely different from traditional Polymers. Exceptional feature of a dendrimer includes a high degree of structural symmetry, a density gradient displaying an intra-molecular minimum value and a well defined number of terminal groups. Dendrimers are normally used as carriers for drug delivery especially for oral, ocular and transdermal delivery. Oral drug delivery system are very important to the field of medicine, since most of the common illness are treated via oral route. Encapsulation and conjugation of drug with dendrimers have shown immerse employment for delivery of hydrophobic and labile drugs. Anticancer and antihypertensive drugs are most promising candidates for oral route using dendrimer as carrier. Dendrimers drug delivery system are therefore increasingly viewed as an advantageous for bioactive like drugs and gene. Although dendrimer drug delivery requires attention to certain manufacturing and biological consideration to be successful.

ABSTRACT
Oncolytic virus is a wonderful discovery of 21^st century. The basic concept of Oncolytic virus was developed since 1946 but it was not produce its effect properly. Now latest technology and modern biotechnology introduce a very efficient Oncolytic virus. This is a genetically modified virus that can treat various type of cancer with fewer side effects than other treatment of cancer. It follows different mechanism of killing tumor by specifically replication; induction of tissue necrosis factor; activation of immunity and treat incurable cancer even in metastatic stage of cancer so it is also effective in leukemia. Oncolytic virus therapy is undergoing in clinical trial and shows better results.
This article covers brief knowledge of cancer, Virus and Oncolytic virus. It is helpful to understand history, mechanism, benefits and clinical data of Oncolytic virus. And a summary of marketed product ready to launch in near future.

Abstract
Drug product recall is an action taken to withdraw or remove a batch or an entire production run of a drug product from distribution or use and return them to the manufacturer. It is usually done due to the discovery of deficiencies in quality, efficacy or safety in the marketed drug products. Defective drug products related to quality includes adulterated or spurious drugs. Safety and efficacy related recalls include serious adverse reactions and death. Recalls also include drugs prohibited under the law and also those products for which product licenses are suspended/ cancelled. In USA, guidelines for drug product recall are described under 21 CFR Parts 7, 107 and 1270.  In Australia, guidelines for drug product recall are described under section 65F of the Trade Practices Act 1974. Sections 2(2), 4, 5 and 7 of the European Communities Act 1972 and Directive 2001/95/EC on general product safety are followed in UK for drug product recall. In India, references for drug product recalls, complaint and adverse reactions are mentioned in Para 27, 28 of Schedule M and conditions of license for defective product recall in Rule 74(j) and Rule 78(i) of the Drugs and Cosmetics Act, 1940 and Rules there under. But no effective and uniform recall procedure and guidelines are formulated yet in India. This paper presents a comparative study of drug product recall guidelines in USA, UK and Australia. Based on this comparative study suggestions are provided to develop regulatory guidelines for drug product recall in India.

Abstract
Over the past several years spectroscopy has become the preeminent technique for determining the structure of organic compounds. The study of recoilless nuclear resonant absorption or fluorescence is more commonly known as Mossbauer spectroscopy. From its first origins in 1957, it has grown rapidly to become one of the most important research methods in solid-state physics and chemistry. Mossbauer spectroscopy uses the nuclear properties to get information regarding the environment surrounding the nucleus. This technique is now valid application in diverse fields, such as solid state physics, metallurgy, chemistry and biochemistry. For example, it is possible to use this method for estimating the iron or tin content in ores, alloys and wasters in a non-destructive manner to concentration down to 0.03 percent in a short time of  the order of 10 minutes. The technique can also detect the relative percentage of  different charged states of the same atom, for example fe2+ and Fe3+ present in the material. This is somewhat difficult to get from any other technique.
