Abstract

Rosuvastatin calcium is a salt form of rosuvastatin with antilipidemia activity. Rosuvastatin Calcium classified in class two of Biopharmaceutics Clasification System (BCS)  has low solubility in water (17.96 mg / L) and high permeability. Based on this, rosuvastatin calcium needs to be formulated appropriately in order to produce high bioavailability and maximum therapeutic effect. The bioavailability of BCS 2 drug is determined by the dissolution rate of the drug in gastrointestinal fluid so that a technique is needed in formulating the drug. This study aims to develop a formulation technique for rosuvastatin calcium tablets through liquisolid technique and formation of inclusion complexes with ?-cyclodextrin in order to increase the rate of dissolution. Tablet formulation with liquisolid technique was made with a concentration of 10% rosuvastatin calcium in propylene glycol, with a ratio of US2® (carrier) and Aerosil 200 (coating) made with a ratio of 10: 1 and 20: 1. In addition to the formulation with liquisolid technique, formulations were also carried out with the complex inclusion technique of rosuvastatin calcium-?-cyclodextrin using kneading method and freeze drying method with a mol ratio of 1: 1 and 1: 2. The liquisolid system and inclusion complexes formed were characterized using FTIR and SEM. Characterization results indicated changes in the form of polymorphous rosuvastatin calcium. Tablet formulations were made by direct compression using a liquisolid system and an inclusion complex equivalent to 10 mg of rosuvastatin calcium. Based on the results of the ANOVA statistical test and further LSD tests showed that calcium rosuvastatin tablets made with liquisolid and inclusion complexes can increase the dissolution rate compared to pure rosuvastatin calcium tablets and inovator rosuvastatin calcium tablets. The highest dissolution rate was produced by liquisolid R20: 1 tablet at 60 minutes at 85.53 ± 1.02% in an enzyme-free simulated gastric fluid dissolution medium and 110.02 ± 1.71% in an enzyme-free simulated intestinal fluid dissolution medium.

Abstract

The discovery of micro RNA (miRNA) in 1993 by Ambros and colleagues has a huge influence in pathogenesis theory, diagnosis and treatment approach of some diseases. Some studies have conducted to seek the association alterations of miRNA expression to incidences and severity of preeclampsia (PE). We have reviewed some studies that conducted to seek the association of miRNA and PE and we discussed the role of various miRNAs in PE pathogenesis. In summary, we have shown that many researchers have given evident that the different placental and plasma miRNA expression is associated with PE. Some studies also identified the novel candidate of miRNAs (and their pathways) that may be of etiologic relevance in the pathogenesis of PE. Base on review, specific miRNA have a role to down regulate of anti apoptosis genes, regulate angiogenics growth factors such as angiogenin, vascular endothelial growth factor (VEGF) B (VEGF-β), cysteine-rich 61 (CYR61), Placental growth factor (PlGF) and VEGF-A that have a role in angiogenesis. miRNA also have a role in  survival, migration, and capillary tube formation of HUVEC by targeted of c-kit. Some miRNAs target genes that participate in immunologic dysfunction, cell adhesion, cell cycle, and signaling. miRNA also have a roles in endothelial cell response to hypoxia, cell differentiation, and survival. A miRNA influence calcium signaling through negative regulations of the calmodulin-coding mRNAs, Mef2a and Gata4, mainly in smooth muscle cells that contribute to PE pathogenesis. These investigations provide novel targets for further investigation of the pathogenesis of PE and these differential miRNAs may be potential markers for the diagnosis and provide a potential therapeutic target for PE. Further investigations on posttranscriptional regulation in PE to evaluate biologic effects of identified miRNAs (including confirmations of miRNA and target gene interactions) are needed

Abstract

TARGETING DESIGN TO THE LUNGAND PULMONARY INTRACELLULAR STRUCTURE OF ENDOGENOUS GENE BY IRQ MODIFIED NANO CARRIER. Inhibition of angiogenesis is a novel strategy for the treatment of lung cancer. For efficient therapy, vectors must firstly reach the target tissue and subsequently demonstrate an efficient intracellular targeting. In this study, we attempted to design a vector for in vivo pulmonary targeting which was able to deliver small interfering RibonucleicAcid (siRNA) for endogenous gene of angiogenesis in pulmonary endothelial cells. siRNA was condensed with polycation agent and encapsulated in lipidous nano carrier. To obtain high level of lung accumulation, we controlled the surface of nano-carrier by changing the length of Polyethylene glycol (PEG) moiety. These nano carriers showed prominent Ribonucleic acid interference (RNAi) effect, when luciferase gene was used as a target. In addition, an efficient transgene knockdown of Vascular Endothelial Growth Factor Receptor 1 (VEGFR1), a responsible gene of angiogenesis, can be obtained by the Instantaneous Respiratory Exchange Ratio (IRQ) modified nano carrier with the use of Stearyl-R8 (STR-R8) peptide, known as an endosomal membrane inducer. In conclusion, pulmonary targeting of nano carrier by encapsulating siRNA can be developed by controlling the PEG length and the structure of nano carrier for efficient intracellular targeting.

Abstract

Cellulite is a condition in the skin that changes the topographic of the skin surface. Caffeine can be used as an active compound for its slimming effect. To improve the penetration into the skin and increasing its solubility for cellulite treatment, caffeine was formulated as niosome vesicles. Niosome was made by using thin layer hydration method. Span 60, caffeine and cholesterol dissolved in chloroform and evaporated to produse a thin layer. The dispersion of caffeine and niosome was formulated in the form of gel using 6% of HPMC gel base. To determine the formulation stability, caffeine niosome gel was stored at a room temperature and accelerated condition using climatic chamber at a temperature of 40⁰C, 75% RH for 28 days. The result was then compared with caffeine gel. The diffusion rate of both gels was determined in vitro using flow through method. The results showed that the niosome system improved the solubility of caffeine up to 20,34 mg/ml and also showed that the pH and viscosity of caffeine niosome gel were stable under room temperature and accelerated condition.The diffusion test showed that the flux of caffeine niosome gel is 13.991 μg/cm2Keywords : Caffeine, niosome, cellulite, diffusion test.

Abstract

Nigela sativa is the plant in which the seeds have a strong anti inflammatory effect. The compound that responsible to perform anti inflammation effect is thimoquinon, that contained in volatile constituents of Nigella sativa oil. Later it was found that even the fixed oil of Nigella sativa has greater anti inflammation effect than thimoquinon. Limited usage of oil or powder have a problems in bioavailability. To overcome this problem, the self nanoemulsion formula development is done to enhance the bioavailability. Nanoemulsion contain 200μL Nigella sativa oil per 1 g mixture of oil phase made by VCO, Cremophor RH40,  polietilen glikol 400 rasio 1:7:2.
