Spices, comprising different parts of a plant (seeds, bark, etc.), are substances used for adding flavor to and preserving food items. They possess a myriad of health benefits, uses of which are documented in ancient literature. <em>Panch phoron</em> is a mixture of five spices, comprising whole seeds of cumin, fennel, fenugreek, mustard and black cumin. It is widely used in India, especially Eastern India, for adding flavor to food in daily cooking. The present study delves into various pharmacological properties of each of the five seeds comprising <em>Panch phoron</em> and is necessitated by the current interest in plant products as a cheaper and far better alternative than the synthetic drugs available but associated with side effects. It was seen that the seeds have myriad properties such as antimicrobial, antioxidant, antitumorigenic, anti-inflammatory, antidiabetic, gastroprotective and cardioprotective and may be used for the treatment of diabetes, cancer, inflammation, kidney problems, liver problems, etc., following proper scientific validation and long-term trials. The review aspires to scientifically validate the vast traditional use of this spice in the Eastern Indian cuisine and its immense scope in herbal therapeutics in the future.</p> 2019-08-13T00:00:00+00:00 ##submission.copyrightStatement## http://jpionline.org/index.php/ijpi/article/view/368 Production and Applications of Radiopharmaceuticals: A Review 2019-09-16T12:10:08+00:00 Nihar Ranjan Kar nihar_795@rediffmail.com <p>Radiopharmaceuticals are exclusive medicinal formulations including radioisotopes which are utilized in foremost clinical areas for study, diagnosis and/or therapy.

Hari Kumar shweta_ag26@rediffmail.com Rajeev Garg shweta_ag26@rediffmail.com <p><strong>Aim:</strong> Nanostrucured Lipid Carriers (NLCs) are the 2nd generation of Solid Lipid Nanoparticles (SLNs) designed to overcome limitations of SLNs. Their characteristics can be modulated by variations in formulation and process variables. The present study was aimed at investigating the influence of formulation variables, solid: liquid lipid ratio and stabilizer amount on some important characteristics of Quetiapine Fumarate Nanostructured Lipid Carriers (QF-NLC) like percent Entrapment Efficiency (%EE), Particle Size (PS), Polydispersity Index (PDI) and Zeta Potential (ZP). <strong>Methods and Materials:</strong> The study was carried out by varying the ratio of solid:liquid lipid and stabilizer amount sequentially in two sets of experiments and studying their impact on the selected characteristics of QF-NLC. Hot emulsification followed by ultrasonication was the method of preparation. Precirol ATO5, oleic acid and Phospholipon 90G (P90G) were selected as the solid lipid, liquid lipid and stabilizer respectively. <strong>Results: </strong>On varying the solid: liquid lipid ratios in the first set of experiments, %EE, PS and ZP ranged from 65.05-75.52%, 281.5-150.4nm and -16.4- -21.4mV respectively showing that decrease in the ratio was related to %EE and ZP inversely and to PS and PDI directly. Increase in the amount of P90G in the second set of experiments showed %EE to be affected positively and PS and PDI negatively. ZP was less sensitive to changes in P90G.<strong> Conclusion:</strong> From the study it can be concluded that by varying the chosen formulation variables a QF-NLC formulation with desired characteristics can be formulated for the chosen objective.</p> 2019-09-16T00:00:00+00:00 ##submission.copyrightStatement## http://jpionline.org/index.php/ijpi/article/view/369 Comparative Modeling, Characterization and Energy Minimization Studies of Aquaporin 9: An Exclusive Target Protein for Rheumatoid Arthritis 2019-10-16T13:21:01+00:00 Surojeet Das dean.fobt@srmu.ac.in Parul Johri dean.fobt@srmu.ac.in Ruchi Sharma dean.fobt@srmu.ac.in Monika Kashyap dean.fobt@srmu.ac.in Shivani Singh dean.fobt@srmu.ac.in Sachidanand Singh dean.fobt@srmu.ac.in <p><strong>Background:</strong> In the absence of the experimentally determined structure, computer aided protein structure prediction, evaluation and their energetically stable structure identification is the only way out of the problem. The main objective of the study was to perform the structure prediction of Aquaporin 9 (APQ9) the most targeted protein for rheumatoid arthritis, using <em>in-silico</em> methodology and validate the generated models. <strong>Methods:</strong> Secondary structure prediction of AQP9 was performed using GOR4, SOPMA and CFSSP algorithm. This was followed by the three-dimensional structure identification from MODELLER, LOMETS and MUSTER server. Many models were built and the best amongst them was identified on the basis of their DOPE score. RAMPAGE was used to validate these models and finally the selected model was energetically stabilized. <strong>Results:</strong> Amongst the 4 predicted models, model predicted using MODELLER software with 1FX8 PDB template (MODELER MODEL 2) was selected as the best. This model showed the best results in Ramachandran plot validation. In the Ramachandran Plot, 223 residues (95.7%) were found to be in the favored region, 9 residues (3.9%) in the Allowed region and the rest 1 residue (0.4%) in the Outlier region. Energy minimization calculations were also done for the four models using SPBDV software and Modeler Model 2 model showed the least energy (E= 3484.038 KJ/mol).<strong> Conclusion:</strong> The accurate three-dimensional structure prediction of proteins is a grand challenge now. Massive amount of sequence and structural data is available now with low cost. The choice of one or other method depends solely on the type of protein sequence and the quality of the predicted structure. The accurate structure prediction, fold recognition, energy calculation, side chain modeling and target template identification are the crucial edges of the molecular modeling process which need to be scrutinized for the best predicted model.</p> 2019-09-16T00:00:00+00:00 ##submission.copyrightStatement## http://jpionline.org/index.php/ijpi/article/view/334 GC-MS Analysis of Bio-active Compounds in Ethanolic Extract of Leaf and Stem of Asclepias curassavica L. 2019-10-16T13:21:16+00:00 Varsha Shelke varshalkolhe@gmail.com Meeta Bhot varshalkolhe@gmail.com <p style="text-align: justify;"><strong>Background:</strong> The presence of phytochemical constitutes has been reported from species of the family Asclepiadaceae.

Aim and Objectives: To evaluate the immunohistochemical expression of MUC4 in oral epithelial dysplasia and to compare the immuno histochemical expression of MUC4 in Oral Epithelia Dysplasia (OED) and its expression in the normal tissue specimens. <strong>Materials and Methods:</strong> The present retrospective study was undertaken to compare and evaluate the expression of MUC4 in oral epithelial dysplasia and normal. The study comprised of 45 cases of oral epithelial dysplasia and 10 controls. Control specimens were obtained from healthy oral mucosa of individuals undergoing oral surgery for disimpaction of third molars and orthodontic extractions. Serial sections of 3-4 microns thickness were made from the tissue blocks and were stained using immunohistochemical marker MUC4, using an immunoperoxidase technique (ABC method). The semi quantitative analysis of the stained sections was done by light microscopy according to the Immunoreactive Score (IRS) by Remmele and Stegner which evaluated percentage of positive cells and the staining intensity. <strong>Results:</strong> Less than 10% of positive cells were seen in 9 cases of mild dysplasia out of 15 cases and 3 cases showed 10 to 50% of positive cells. Whereas less than 10% of positive cells were seen in 6 cases of moderate dysplasia out of 15 cases and other 9 cases showed 16% and 42% of positive cells respectively. However, in severe dysplasia positive cells percentage increased to 10 to 50% in 10 cases and other cases showed less than 10% respectively. <strong>Conclusion:</strong> In the OED group a gradual increase in the staining pattern was observed from mild to moderate to severe dysplasia. Severe dysplasia cases exhibited the staining of entire thickness of epithelium. Thus, it may be concluded that MUC4 plays a very important role and can be reckoned as a handy tool or marker for diagnosis of OED.</p> 2019-08-13T00:00:00+00:00 ##submission.copyrightStatement##
