INTRODUCTION
Urbanization, industrialization, changes in lifestyles, population growth and ageing all have contributed for epidemiological transition in the country. The absolute number of new cancer cases is increasing rapidly, due to growth in size of the population, and increase in the proportion of elderly persons as a result of improved life expectancy following control of communicable diseases. In India, the life expectancy at birth has steadily risen from 45 years in 1971 to 62 years in 1991, indicating a shift in demographic profile. It is estimated that life expectancy of Indian population will increase to 70 years by 2021–25. Such changes in the age structure would automatically alter the disease pattern associated with ageing and increase the burden of problems such as cancer, cardiovascular and other non-communicable diseases in the society.The latest global figures show that in 2004, there were 11.4 million cases of cancer diagnosed worldwide, and 75% of these were in Europe, the Americas and the Western Pacific Region. The Western Pacific Region includes China, Malaysia, Japan, Australia and New Zealand. The lowest numbers of cases were diagnosed in the Eastern Mediterranean region (includes Saudi Arabia, Egypt Iraq, Morocco, Tunisia) and Africa.
There were differences in the top three most common cancers in each region. The top three included lung cancer in all regions except Africa and included breast cancer in all except for the Western Pacific region. Cervical cancer was in the top three in Africa and South-East Asia only and bowel cancer in the top three for Europe only. Prostate cancer was in the top three in Africa and the Americas.Let us discuss one of the most promising targets of these days, which when overexpressed may cause cancer, i.e.;HISTONE DEACETYLASE.

ABSTRACT
Solubility, the phenomenon of dissolution of solute in solvent to give a homogenous system, is one of the important parameters to achieve desired concentration of drug in systemic circulation for desired pharmacological response. Low aqueous solubility is the major problem encountered with formulation development of new chemical entities as well as for the generic development. The insufficient dissolution rate of the drug is the limiting factor in the oral bioavailability of poorly water soluble compounds. This review discusses BCS classification, carriers for solubility enhancement and different techniques for solubility enhancement.Various techniques are used for the enhancement of the solubility of poorly soluble drugs which include micronization, nanonization, sonocrystallization, supercritical fluid method, spray freezing into liquid and lyophilization, evaporative precipitation into aqueous solution, use of surfactant, use of co-solvent, hydrotropy method, use of salt forms, solvent deposition, solubilizing agents, modification of the crystal habit, co-crystallisation, complexation and drug dispersion in carriers.Selection of solubility improving method depends on drug property, site of absorption, and required dosage form characteristics.With the advent of combinatorial chemistry and a high throughput screening, the number of poorly water soluble compounds has increased solubility. A success of formulation depends on how efficiently it makes the drug available at the site of action.The purpose of this review article is to describe the techniques of solubilization for the attainment of effective absorption with improved bioavailability.

Abstract
Pulsatile drug delivery systems (PDDS) are gaining importance in the field of pharmaceutical technology as these systems deliver the right dose at specific time at a specific site. A pulsatile drug release, where the drug is released rapidly after a well defined lag-time, could be advantageous for many drugs or therapies.A pulse has to be designed in such a way that a complete and rapid drug release is achieved after the lag time so as to match body’s circadian rhythms with the release of drug which increases the efficacy and safety of drugs by proportioning their peak plasma concentrations during the 24 hours in synchrony with biological rhythm. Pulsatile release systems can be classified in multiple-pulse and single-pulse systems. Various techniques are available for the pulsatile delivery like pH dependent systems, time dependent systems, etc. A popular class of single-pulse systems is that of rupturable dosage forms. Advantages of the pulsatile drug delivery system are reduced dose frequency; reduce side effects, drug targeting to specific site like colon and many more. Now in market varies technologies of pulsatile drug delivery system like Pulsincap, Diffucaps etc. are launched by pharmaceutical companies.

ABSTRACT
Laccases are an interesting group of multi-nuclear copper-containing oxidoreductases, which have been subject of intensive research in last decades due to their ability to oxidize both phenolic and nonphenolic lignin related compounds as well as highly recalcitrant environmental pollutants, which makes them very useful for their application to several biotechnological processes. These oxidase enzymes catalyze oxidation of substrates at the expense of molecular oxygen and produce water as the only by-product. Lacasses are present in higher plants, bacteria, fungi, insects and lichens. The oxidative ability of laccases is employed in a number of industrial and environmental applications including bioremediation, food technology, nanobiotechnology, medicine, pulp and paper industry, textile industry, and cosmetology. Owing to its versatility, laccase is continuously under investigation for new applications. In the recent years, laccases are also used as cleaning agents for certain water purification systems, as catalysts for the manufacture of anti-cancer drugs and even as ingredients in cosmetics. More recently, it is also used in the design of biosensors, biofuel cells, as a medical diagnostics tool and bioremediation agent to clean up herbicides, pesticides and certain explosives in soil. This paper reviews the occurrence, mode of action, general properties, production, immobilization, molecular cloning, and important application of laccases within different industrial and biotechnological area.

ABSTRACT:
Chitosan has been the subject of interest for its use as a polymeric drug carrier material in dosage form design due to its appealing properties such as biocompatibility, biodegradability, low toxicity and relatively low production cost from abundant natural sources. Hydrogels are a unique class of macromolecular networks that can hold a large fraction of an aqueous solvent within their structure. The objective of this paper is to give a brief review on the fundamentals and recent advances in chitosan based hydrogel for e.g., thermosensitive hydrogel variants which precludes the need of surgical implantation as well as the description of the release mechanism of bioactive molecules from these hydrogels which traps a drug and then releases the active compound by "Swelling" or expanding inside of specific tissues, thus allowing a higher concentration of the drug in a biodegradable format. This article presents an overview of the newest developments and applications of Chitosan based hydrogel for controlled drug delivery system.

Abstract:
There was a point in time when packaging in pharmaceutical industry is symbolized for substantial safeguard, for identification and for merely endowing with a piece of information to any person who agree to it. But the changing scenario has been conveyed an assortment of changes, as in this day and age packaging provides the prevention of product tampering and counterfeiting, the assurance of product dispensing accuracy, child protection and the promotion of patient compliance with product dosage schedules. In the precedent time we used packaging materials, labels, holograms and some introductory communications; but these days together with them we use mobile applications, an innovative and creative unit, altering labeling standards, luxurious packaging, a packaging development team, anti-counterfeiting packaging extravaganza, hi-tech module for packaging demonstrate and an intelligent outlook. Packaging schoolwork has such an individual place in the market of counterfeit or fake drugs as nowhere. Packaging developer has an only effort to engender a special design that can competent with both fake brands and generic brand of that drug with ‘Me-too’ names.

Abstract
The effect of TDZ on regeneration studies of cotton G.arboreum cv PA255 was performed for in-vitro culture studies, healthy and disease free seeds, after surface sterilization were inoculated on seed germination media. Seeds germination efficiency was observed to be 73.38%. Shoot tips and cotynode explants aseptically isolated from in Vitro germinated seedlings of 7 and 14 days old were inoculated on MS basal salt supplemented with 30 gm/L glucose, 10 mg/L thiamine, 100 mg/L Inositol with four different concentration of TDZ. The proliferation of 7 and 14 days old shoot tip was found to 100% in media combination with 0.08 TDZ and 0.02 TDZ respectively. Cotynode explants of 7 days old was 100% responded in 0.02 TDZ and 0.08 TDZ, 14 days old cotynode shows highest 85% explants responded in 0.02 TDZ media combination but multiple shoots observed higher in 0.05 TDZ medium.TDZ induces callus formation and inhibit root formation, TDZ shows good responsein very small concentration otherwise increase concentration more than 1 mg/l it shows toxic effect on explants and completely dried. Browning and subsequent death of the cultured explants are major problems in TDZ supplemented media. Calculate the amount of phenol excreted from shoot tip and cotynode during in vitro regeneration of cotton cv. PA255. In the media combination 0.1mg /L TDZ evaluate highest phenol secreted, shoot tip secrete average 0.014mg and cotynode secrete 0.022mg phenol by per explants.

ABSTRACT
Sodium is an essential element for all animal life (including human) and for some plant species. In animals, sodium ions are necessary for regulation of blood and body fluids, transmission of nerve impulses, heart activity, and certain metabolic functions. Sodium is the chief cation in extracellular compartment of animal body.
Sodium plays a vital role not only in human body but also in various food types. Sodium chloride is the principal source of sodium in the diet, and is used as seasoning and preservative, such as for pickling and jerky; most of it comes from processed foods.
The sodium content in various foods can be analyzed by using Flame Photometry. Flame photometry also called flame atomic emission spectrometry is a branch of atomic spectroscopy in which the species examined in the spectrometer are in the form of atoms.
The samples used for analysis are junk foods which have become a common trend among all generations. A total of 15 junk foods were processed and analyzed for estimating the sodium content in them by Flame Photometry.
Based on the analysis the samples were categorized into low, moderate and high sodium containing foods. The analysis helps in creating awareness among all the generations to reduce the sodium intake in order to prevent problems like hypertension, hyponatremia, hypernatremia and associated medical complications in their future.

ABSTRACT
A supernumerary marker chromosome is an extra structurally abnormal chromosome of unknown origin. Various factors contribute to the difficulty of clarifying the phenotypicrisks of super numerary marker chromosomes (SMC), including differences inthe size, structure, and origin of marker chromosomes.

All marker chromosomes do not contribute the same risk of recurrence. Therefore characterization of the marker chromosomes is of utmost importance for Genetic Counseling. Different molecular techniques can be used to identify the chromosome material present in the markers. In the present retrospective data analysis of 15,000 karyotypes of all patients referred to the Center of Medical Genetics, Sir Ganga Ram Hospital from 1998 to 2012. For constitution chromosome abnormality detection, we found fifteen (0.01%) patients had presence of the SMC. Of these fifteen, eight markers had been characterized after FISH was introduced in the year 2004. This contributed to personalized Genetic Counseling and help for future pregnancies.
