FABRICATION AND CHARACTERIZATION OF CURCUMIN
NANOEMULSION AS COLLOIDAL CARRIER
Department of Chemical and Environmental Engineering, University of Nottingham
(Malaysia campus), Selangor 43500, Malaysia
Curcumin, a yellow figment extracted from Curcuma Longa
dried rhizome, was found to have significantpharmaceutical activities, for instance anti-cancer, anti- carcinogenic, anti-inflammatory, anti-oxidantand etc. However, bioavailability of curcumin after oral administration is always low due to its extremelylow solubility in water at acidic or neutral pH. In order to improve the absorption rate of curcumin invivo
, curcumin encapsulated nanoemulsion was developed using nanoemulsifying approach associatedwith ultrasonic cavitation. Nanoemulsions with droplets size in the range of 20-100nm were successfullyprepared using Brij56/Span20 as surfactants. Colloidal characteristics of resultant formulations wereprecisely studied using Zetasizer, up to 50%w/w of curcumin solution was well rendered in water with 5or 10%w/w surfactant. Obtained results showed that curcumin nanoemulsion Particle Size Distribution(PSD) was a function of surfactant HLB number and surfactant concentration. Curcumin 0.1% addedto water had a negligible effect on particle size, this was generally disagreed with most of the publication.
Despite an approximately 0 zeta potential was detected in all formulations, Zeta-Average andPolydispersity Index (PdI) of selected formulations indicated promising physical stability of formulationafter 10 days storage.

The aim of this research was to know the potency of garlic (Allium sativum
) extract as anti allergy inmice. The mice were divided into the negative control groups (mice were given saline solution perorally);positive control group (mice were given saline solution perorally and given ovalbumine 1µg/kg BWintraperitonelly); garlic extract groups (mice were given doses of 100; 200 and 400mg/kg garlic exctractperorally and given ovalbumine intraperitoneally at dose 1µg/kg BW 60 minute after administration garlicextract). Results of this research indicated that the positive control significantly increased immunoglobulinE production compared with control negative. While administration of the garlic exctract at dose 200and 400mg/kg BW but not garlic exctract at dose 100mg/kg BW significantly inhibited the increase ofimmunoglobulin E in mice which were given ovalbumine. These results suggest that garlic exctractat dose 200 and 400mg/kg BW has antiallergy properties.

the melting points of PHBV, thermal decomposition of the material via random scission process maytake place leading to shorter chains with terminal carboxyl groups. These terminal carboxyl groups maytrigger chemical reactions with the reactive sites in ENR. This melt reaction may serve as in-situcompatiblization for these immiscible green polymer blends. Isothermal melt reaction of PHBV withENR has been detected at temperatures ranging from 220 to 234°C. The rate of reaction increases withthe increasing isothermal melt reaction temperature (T ). Merging of the separate glass transition
temperatures (T ) (corresponding to those of the neat constituents) into one T may reflect increasing
adjustment of the two constituents after melt reaction. After melt reaction, finer and uniformly dispersedof PHBV spherulites in the matrix of ENR are observed. The rate of crystallization of PHBV has beenimpeded significantly after melt reaction for all blend compositions. These blends may be proposed aspotential pharmaceutical packaging material.

Institute of Microengineering and Nanoelectronics, Universiti Kebangsaan Malaysia,
We present a simple and low cost fabrication of Microfluidic mixer for use in different applications inMicro Total Analysis Systems especially for automated perfusion of multiple solutions to a single cellculture chamber. This device consists of 6 inlets and 2 outlets with additional 3 inlet/outlet channels forflow rate alteration and other mixing purposes such as electrophoresis activation, which is capable ofproducing mixtures of the various solutions. All the inlets are connected to PTFE and silicone tubings
using special PDMS fittings technique for fluid leakage avoidance. The inputs are controlled by aprogrammable micro-syringe pump in order to activate each input in any sequence of time. Typicalmicroscopic glass slides are utilized as a substrate for fabrication of microchannels and chamber whichhas the minimum effect on most of biology samples. The same un-etched glass is used as cover glass forbonding purposes. Using photo-resist as an etch mask instead of some deposition methods makes theprocedure more convenient and cost effective compare to other expensive techniques such as DRIE,etc. The baking time of photo-resist is a critical factor for longer resistance against etchant solution whichis optimized by this method. In addition the etchant concentration in wet etching process is discussed toachieve a decent surface and wall characteristics for bio-applications. A smooth channel surface withacceptable sharp wall edges makes this procedure suitable for many applications which vertical walls arenot crucial. Different dye samples were tested inside the chamber and promising results were attained.

Both Polyvinylpyrrolidone (PVP) and Acrylamide (Acr) are the polymers commonly used inpharmaceutical formulations. To prepare transdermal drug delivery systems (TDDS), none of these canbe used alone to make a film, so they are mixed with suitable other polymers .The present study dealswith the synthesis of a novel copolymer, its characterization and the evaluation of film properties. Thesepolymers have been reacted under controlled conditions in a specially designed jacketed reaction vessel
R E T R A C T E D
and process optimization was done on the basis of variables like initiator (ammonium persulphate)concentration, the ratio of virgin polymers and physical environment of the reaction vessel to make agraft copolymer. The principle of polymerization used was atom radical copolymerization. The synthesismethod was optimized for the optimum graft yield by evaluating the effect of the process variables onthe graft yield. The synthesized copolymer has been characterized by X-ray diffraction (XRD), Differentialscanning calorimetry (DSC), Fourier transformed infrared (FTIR) spectroscopic technique and scanningelectron microscopy (SEM) to confirm copolymerization. The film was casted with graft copolymer bysolvent evaporation technique using glycerin as plasticizer. The film alone and loaded with the drugMethotrexate (Mtx) were tested for their water vapor transmission (WVT), moisture absorptivity (MA),tensile strength (TS), film thickness, flatness and weight variation. The results of the tests revealed thatthe copolymer alone can be proposed to be a suitable polymeric material for making patches for drugdelivery specifically for transdermal drug delivery systems.

release profiles were assessed using automated vertical diffusioncells (Microette) with cellulose membrane to simulate skin barrier. a-Tocopherol (5% w/v) was formulatedseparately in 15%w/v of the oils in ethanol. Samples were collected hourly for the first eight hours andthen at 24 hours for cumulative drug release profiles using rapid resolution high chromatography. Thesynthesized SVCO containing 34.38% caprylic acid showed a more enhanced drug release profileswithin the first 8 hours than VCO. After 24 hours, the cumulative amount of drug release for VCO was31.02%, while for SVCO the amount was increased to 56.90%. The results indicated that caprylic acidin the SVCO influenced the in vitro
release profiles of the model drug, thus highlighting its potential as apenetration enhancer of a-tocopherol.
