    • Endometriosis –A New Age Disease

      Endometriosis is the biological complication that occurs when the lining of the uterus called endometrium grows outside the uterine cavity. It affects females in their reproductive years, and is an estrogen-dependent condition. In US about 5 million women have endometriosis with different symptoms. Endometriosis is known to occur when the lining of the uterus called the endometrium, grows in other places such as fallopian tubes, ovaries or along the pelvis .The major issues that limit the currently available endometriosis treatment are lack of awareness, delay in diagnosis, high cost, long-term treatment and recurrence. The impact includes fertility, sexuality and ability to work, play and personal relationships. Treatment for endometriosis involves pain medication, hormone therapy, surgery, or a combination of both. However to avoid recurrence hysterectomy or total removal of the uterus may be a 'last resort' option. Download
    • Needs and Necessity of Polyploidy in Medicinal Plants

      Polyploids are organisms with multiple sets of chromosomes in excess of the diploid number. Polyploidy is common in nature and provides a major mechanism for adaptation and speciation. Approximately 50-70% of angiosperms, which include many crop plants, have undergone polyploidy during their evolutionary process. Flowering plants form polyploids at a significantly high frequency of 1 in every 100,000 plants. Many studies have been carried out to understand the nature of polyploidism. The polyploid condition may bring about several advantages compared to the diploid state. Polyploids often show phenotypes that are not present in their diploid progenitors or exceed the range of the contributing species. Some of these traits may play a role in heterosis or could favor adaptation to new ecological niches. Advances in genomics and sequencing technology may create unprecedented opportunities for discovering and monitoring the molecular effects of polyploidization. Through this review, we provide an overview of technologies and strategies that may allow an in-depth analysis of polyploid genomes. After introducing some basic aspects on the origin and genetics of polyploids, we highlight the main tools available for genome and gene expression analysis and summarize major findings. In the last part of this review, the implications of next generation sequencing are briefly discussed. The accumulation of knowledge on polyploid formation, maintenance, and divergence at whole-genome and subgenome levels will not only help plant biologists to understand how plants have evolved and diversified, but also assist plant breeders in designing new strategies for crop improvement.

    • Assessment of Serum Paraoxonase Levels In Patients Fatty Liver Disease

      The liver plays a key role in the synthesis of serum Paraoxonase (PON). It is circulating enzyme in the serum and bound to HDL. PON has function as an anti-oxidant effective of protecting low density lipoproteins against peroxidative reactions. PON1 levels have been reported in a variety of diseases along with the liver diseases. The study was planned with the aim of ascertaining the diagnostic use of level of the PON in various diseases. The two group of patients were selected based as Fatty Liver disease patients and control group patients. The blood samples were withdrawn from the patients. The various biochemical parameters such as fasting blood glucose, lipid profiles, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma glutamyl transferase (GGT) levels were reposted in the two groups of the patients. The study has established PON levels were declined in patients with fatty liver disease. With the specificity and sensitivity of this enzyme being high, it could emerge as a parameter to assess liver function. Download

    • Formulation and In-Vitro Evaluation of Modified Release Delivery of Trazodone Hydrochloride Tablets

      The objective behind this study was to formulate and evaluate Modified release tablet of Trazodone hydrochloride by using different hydrophilic and hydrophobic polymers by Wet granulation technology and to study the effect of different concentrations of polymers on release rate from tablet. Tablets were prepared using carnauba wax as extra fine powder (8.5-28%), hydroxypropyl methylcellulose (HPMC) (2-14.5%), and polyvinyl pyrollidone (PVP K-30) (8.5-30%) as release retardant polymers. The FTIR and DSC analysis does not show any interaction of drug with Excipients. The formulation was optimized on the basis of acceptable pre and post compressional parameters and in-vitro drug release. The resulting formulations produced monolithic tablets with optimum hardness, consistent weight uniformity and low friability. The results of dissolution studies indicated that Batch F8 exhibited drug release of 99% at the end of 12h to provide sufficient concentration for achieving satisfactory therapeutic value for extended period of time. The drug release from Batch F8 formulation was sustained up to 12 h. Fitting in-vitro drug release data from optimized matrix formulation to first order followed by Korsmeyer’s-Peppas indicated that diffusion could be mechanism of drug release. Download
    • A Comparative Study on Different Methods of Granulation on Tablet Properties

      The active ingredient in a formulation represents a very small portion of the overall tablet, then the challenge is to ensure that each tablet has the same amount of active ingredient. Sometimes, blending the ingredients is not enough. The active ingredient may segregate from the other ingredients in the blending process. The ingredients may be incompatible because of particle size, particle density, flow characteristics, compressibility, and moisture content. These incompatibilities can cause problems such as segregation during blending or during transfer of the product to the press as well as separation of the active on the tablet press. Granulating the active ingredient by itself and then blending it with the rest of the ingredients is one solution to the segregation problem. Otherwise, all or most of the ingredients could be granulated together. The best course of action to ensure that each tablet contains the correct amount of active ingredient, especially if the active ingredient is only a small percentage of the tablet ingredients, is to mix the active ingredient thoroughly with some or most of the other ingredients and then granulate the blend (i.e., form the blend into granules). Each granule would contain a little of each of the ingredients, and the active ingredient would be distributed evenly. Different granulation techniques include Wet granulation, Dry granulation and Direct Compression. The method of granulation is chosen based on the ingredient’s individual characteristics and ability to flow, compress, eject, and disintegrate. Choosing a method requires thorough investigation of each ingredient in the formula, the combination of ingredients, and how they work with each other. Then, the proper granulation process can be applied. In this study, work was done to evaluate the different process of granulation techniques for the preparation of tablets. Download
