Retnaningtyas Ekowati, Sumitro S B, Soeatmadji D W, Widjayanto E
Abstract
Water has an important role in the stability of the structure of the albumin protein. Dehydration condition will affect the conformational changes of albumin protein. This study aims to know the role of water in affecting albumin protein conformational changes by means of molecular dynamics simulations. 3D sample of human serum albumin (1AO6) was obtained from the Protein Data Bank and prepared with VEGAZZ program v.3.08. Simulation process was performed with Gromacs v.4.5.1. The simulation process used the force field GROMOS 43a1 for 1000 ps. The results showed that the dehydration by 30% and 40% can make the dynamics of the protein albumin more static and the dynamic pattern is much different compared to normal conditions. Therefore it can be concluded that the decrease in the amount of water can affect the dynamics of the albumin protein effecting the blood viscosity change.

Abstract
The effect of Calotropis gigantea (CG) leaves extract on fibrosarcoma growth and Caspase 3 expression have been evaluated. Mile mice were divided into 5 groups with 7 mice per group, (1) Negative control (CMC-Na 0.5%), (2) Positive control (Methotrexate 2,5 mg/kgBW), (3) 50 mg/Kg BW of CG, (4) 100 mg/Kg BW of CG, (5) 150 mg/Kg BW of CG.  Mice body weights were observed before induced by cancer agent. Then, all mice were injected by 0.1 mL DMBA 25 μg/0.1 mL acetone by subcutaneous injection two times a week for 6 weeks. After treatment, all mice were sacrificed by euthanasia method based on Guideline for the Euthanasia of Animals. Then, mice nodules were taken and washed with PBS. Nodules were weighted and kept in the formaldehyde solution. Then immunohistochemical caspase-3 specimens were made. C. gigantea leaves extract at a dose of 100 and 150 mg/Kg BW were able to inhibit the growth of fibrosarcoma in experimental animals induced DMBA. This extract also improved the apoptotic index of cell, respectively for 20.9 %; 21.5 % and 24.6 %, and increased the caspase-3 expression significantly. Based on those data, C. gigantea leaves ethanol extract was potential to develop as anticancer phytopharmaca agent.

Abstract
Child birth is viewed as a life transition that can bring a sense of accomplishment. However, for some women, birth is experienced as a traumatic event with a minority experiencing post traumatic stress especially in emergency caesarean section. The stress that results from traumatic events precipitates a spectrum of psycho-emotional and physio-pathological outcomes. Post-traumatic stress disorder (PTSD) is a psychiatric disorder that results from the experience or witnessing of traumatic or life-threatening events. To assess the post traumatic stress disorder (PTSD) symptoms among postnatal mothers, a survey approach, non experimental descriptive design on 60 postnatal mothers who underwent emergency lower segment caesarean section selected by simple random sampling technique was conducted. Traumtic event scale (TES), a standardized tool developed by wijma et al., was used to assess the PTSD symptoms. Subjects were assessed for i) child birth experience by a 4 point likert scale (Criterion A of the tool), ii) level of PTSD symptoms (Criterion B,C,D), iii) duration of the PTSD symptoms  (criterion E),  iv) severity of PTSD symptoms (Criterion F). Results showed that 48 (68.3%) out of 60 postnatal mothers had PTSD symptoms. 29 (48.3%) of the postnatal mothers had poor child birth experience and mild post traumatic stress disorder symptoms, 51(85%) mothers had been experiencing the PTSD symptoms. Child birth experience was associated with the demographic variables age at (X2 = 11.314, p=0.02), occupation at (X2 = 12.858, p=0.045) of the postnatal mothers. Level of PTSD symptoms was associated with the demographic variable occupation at (X2 = 10.868, p=0.012) of the post natal mother. Study concludes that screening for PTSD symptoms should be a routine surveillance tool for all post natal mothers and effective interventions to prevent the illness should be strongly targeted.

Shanmuganathan Seetharaman, Harika Balya, Gowthamarajan Kuppusamy
Abstract
Objectives: The present investigation was attempted to develop a natural polymer based cefixime nanoparticles using Trigonella foenum-graecum (Fenugreek) seed mucilage and chitosan as drug carrier to facilitate controlled drug release at the target site. Methods: The Cefixime nanoparticles were prepared by the modified coacervation method. The prepared drug nanoparticles were evaluated for particle size, zeta potential, surface morphology, entrapment efficiency, in-vitro drug release studies and also in-vitro antimicrobial efficiency studies for the selected ideal batch. Results: The prepared drug nanoparticles was found to be the average mean particle size in range from 133.8±8.5 to 446.3.2±20.3nm and zeta potential of greater than +30 mV or less than -30 mV indicate the better physical stability. The surface morphology of the prepared nanoparticles was found to be spherical with smooth surface and entrapment efficiency was found to be 70.4±1.2 to 83.4±2.0. The in-vitro drug release showed a biphasic pattern with initial burst release followed by the sustained release of the drug up to 24h. The MIC50 values of pure drug and prepared nanoparticles for Salmonella Typhi isolates was found to be 250 µg/ml and 125 µg/ml respectively. The disc agar diffusion test revealed that pure drug yielded 9mm clear zone surrounding the disc, whereas the prepared formulation discs produced 12mm clear zone at 125 µg/ml. Conclusions: The developed natural polymer based cefixime nanoparticles facilitate the controlled drug release profile and better zone of inhibition with minimum concentration thereby improving the patient compliance followed by declining the limitations associated with antibiotics.

Abstract
Autism is complexes behaviorally known as neurodevelopmental disorder characterized by significant deterioration in social interaction, mental abilities and communicative abilities. It is deemed a multi-causes disorder that is affected by genetic, immunological and environmental factors and inclusive oxidative stress. Aim of such study was to estimate level of antioxidant enzyme coenzyme Q10 and level of malondialdehyde (MDA) in children with Autism and correlate these results with their language and behavior pattern. The study included 30 Egyptian children with autism and 30 normal children as control group. Their ages ranged between 3 to 6 years. Diagnosis was done using DSM-V and ADI-R. Cases were classified into high and low functioning autism using CARS. We compared plasma levels of coenzyme Q10 and MDA in children with autism and controls. Our results showed significant increased MDA and decreased coenzyme Q10 in autistic children compared to controls. On the other hand, Increased MDA and decreased coenzyme Q10 were not related to severity of autistic features and language abilities among autistic children group. Regarding language abilities of autistic children, there was positive correlation between IQ and total language age and negative correlation between CARS and total language age.

Juni Ekowati, Rahman S D, Isadiartuti D, Widyowati R, Budiati T
Abstract
Ferulic acid (FA) is a highly effective compound with many activities, but it is poorly suited for pharmaceutics application because of its low physicochemical properties. In the present study we synthesized FA through microwave assisted Knoevenagel condensation using malonic acid and 4-hydroxy-3-methoxybenzaldehyde, in the present of organic base as catalyst. The optimization of the synthesis method was done by comparing the base catalyst; that are pyridine, triethyl amine and morpholine. The structure of FA was determined through UV, FTIR, 1H-NMR, 13C-NMR and MS spectroscopic methods. Improvement the physicochemical properties of FA was carried out through the establishment of the non covalent inclusion of FA with hydroxypropyl-b-cyclodextrin (HP-b-CD) by the kneading method. Its physicochemical characterizations were performed by FTIR and 1H-NMR spectroscopic methods, ROESY experiment, differential thermal analysis (DTA), X-Ray diffractometry (XRD) and dissolution rate. Microwave irradiation that assisted synthesis of FA using morpholine as catalyst produced the highest yield compared to other catalysts. All of the   characteristic data showed that non-covalent inclusion of FA/HP-b-CD has been formed. The dissolution rate of inclusion complex of FA/HP-b-CD was increasing significantly compared with FA.

10. Synergistic Antimicrobial Effects of Volatile Oils used in a Polyherbal Formulation
Joydeep Mazumder, Devender Pathak, Rachna Kumria
Abstract
It was observed that each essential oil is having antimicrobial activity. But when combination was used, the antimicrobial property increased significantly. In higher concentrations Cardamom and Coriander oils are having more bactericidal properties than other oils where as in small concentrations all of the oils are having the same properties that was observed on MIC test. It was proved from the experiments that combination with synthetic standard drug like ciprofloxacin increased synergistic activity as compared to single dose of ciprofloxacin or streptomycin. On the other hand, the blend of oils show similar strength like the synthetic drug which has shown a similar zone of inhibition like synthetic drug, when used as standard. Hence the blend of essential oils can replace the use of synthetic drugs and can be proposed as an effective candidate to the patients undergoing multi dose therapy at regular intervals. In an alternative way it can be used with synthetic drug to those patients who are suffering from drug resistance.
