Pierre Lutgen
IFBV-BELHERB, Luxembourg
Title: Artemisia plants are deadly weapons against malaria
Time : 9.30 - 10.00
Biography:
Dr Pierre Lutgen was born 1940 in Luxembourg, studied at the University of Louvain in Belgium and obtained diplomas in chemistry, social sciences and philosophy. He worked during 25 years for the Dupont CY, in research, and during 8 years in the steel industry, mainly in the environmental field. Since his retirement he worked as consultant for health and environment as invited professor at the University in Medellin and for the European Communities in several countries. Over the last ten years he has organized the association IFBV-BELHERB studying and fighting tropical diseases with some 30 academic and medical partners in Africa, South America and Europe. Numerous peer reviewed papers have been published by this team, mainly on herbal medicine.
Abstract:
Since 7 years the association IFBV-BELHERB from Luxembourg has established a working relationship with African and South American universities, in close cooperation with other European research institutions. Several of these partners have run clinical trials with Artemisia annua team. In all these trials a therapeutical effect of 95 % or higher was confirmed by the use over 7 days of whole leaf infusion, capsules or tablets. One of the surprising effects noticed in these trials was that that the artemisinin content had very little impact on the results. This lead us to make an analysis as complete as possible of all the constituents, organic and inorganic, in a large series of A. annua samples from different origins. A. annua from Luxembourg which had shown very promising antimalarial results, excellent bactericidal properties and a strong anti-inflammatory effect contained very little artemisinin but higher concentrations of certain essential oils. The effect of water soluble polysaccharides, phytosterols and saponins has been neglected in the past because most of the A. annua extracts had been obtained with organic solvents. Several papers have shown that A. annua ingested as powdered leaves or in conjunction with fatty food significantly increases the artemisinin concentration in the blood. It is well documented in the literature that A. afra or sieberi which contain little or no artemisinin are extensively used as antimalarials. They contain at least 5 molecules of the same antimalarial efficacy as artemisinin. At Leiden it was found that the anti-HIV activity of A. afra is even higher than for A. annua. More recent research from the Al Quds University has shown that aqueous infusions of several Artemisia species strongly inhibit beta-hematin, like chloroquine did. But the most important finding in several of the clinical trials, especially in Kenya and Uganda, was that people who drink one or two cups of A. annua tea per week become immune against malaria. Similar strong prophylactic results have been obtained with ARTAVOL, a mixture of herbs developed by the Ministry of Health in Uganda, mixture containing Artemisia without artemisinin. Resistance in this case is not related to the killing power of one single molecule like artemisinin but to the polytherapy of the whole plant which not only eliminates the parasites but boosts the immune system, avoiding thus infection, reinfection or recrudescence. Recent clinical trials in Senegal and RD Congo also have shown that Artemisia inusions are more efficient against Schistosomiasis mansoni than Praziquantel

Title: Antidiabetic, anti-lipoperoxidation and hepatoprotective activities of Fraxinus angustifolia and Pistacia lentiscus extracts
Time : 13:15-13:35
Biography:
Professor Djebbar Atmani has completed his Master of Science degree at California State University, Los Angeles (USA) in 1987 and his PhD at the University of Sétif (Algeria) in 2004. He is the acting Dean of the Faculty of Nature and Life Sciences, University of Bejaia (Algeria). He has published more than 15 papers in reputed journals and has been serving as reviewer of many journals.
Abstract:
Fraxinus angustifolia (Lamiaceae) and Pistacia lentiscus L. (Anacardiaceae) are two common Mediterranean plants used extensively in Algerian traditional medicine to cure inflammatory-related disorders as well as symptoms of diabetes. The anti-diabetic effect of F. angustifolia (leaves and bark) and P. lentiscus (leaves and fruits) extracts was evaluated using the streptozotocin-induced diabetes model in rats, whereas anti-lipoperoxidation activity was assessed with the malonaldehyde assay after injection of paracetamol to mice. The results indicate that F. angustifolia leaf extract (50 mg/Kg of body weight) and P. lentiscus leaf extract (100 mg/kg of body weight) induced a significant reduction (60%) of blood glucose level after 2 hours of administration of the extracts. Furthermore, extracts from both plants significantly reduced α-amylase activity. Analysis of liver homogenates showed an important decrease in the concentration of malonaldehydes in the group of mice treated with plant extracts (0.25 ± 0.006 and 0.26 ± 0.03 for F. angustifolia and P. lentiscus extracts, respectively), compared to that of non-treated animals (0,45± 0.005). Furthermore, plant extracts tested with concentrations up to 200mg/kg of body weight showed no signs of toxicity. Moreover, histological examination of the liver revealed significant protection against paracetamol-induced hepatic necrosis. Phenolic compounds identified in plant extracts could take, at least, partial responsibility for the observed anti-hyperglycaemic and antioxidant activities, thereby conferring these plants a promising protective capacity against oxidative stress.

She has published more than 25 papers in accredited journals and has been serving as a reviewer in journal of Pharmacy.
Abstract:
Colletotrichium capsici endophytic fungi isolated from Jamblang plant (Eugenia cumini L.). Endophytic microbes were microbes that spent part or all of their life within plant tissue or of a host plant. They produce secondary metabolites with potent anti-microbial activity. Jamblang (Eugenia cumini L.) is one of the traditional medicinal plants that grow in Indonesia and were known by the layman as a plant that has efficacy as anti-diarrheal and anti-diabetic.This research focussed on isolation of the endophytic microbes from branches of Jamblang plants and their secondary metabolites. Isolation of endophytes were performed in PDA(potato dextrose agar) using direct seed plant. Endophytic fungi isolates that have the greatest antimicrobial activity against the bacteria Staphylococcus aureus, Escherichia coli, and then fermented in Potato Dextrose Yeast (PDY) in large scale. Supernatant was extracted with ethyl acetate solvent.. Ethyl acetate extract fractionated by column chromatography (SiO3, n-hexane- ethyl acetate = 50:1 ~ 1:1) and obtained three fractions. Further, agar diffusion method was performed to assess their anti-microbial activity Antibacterial test results indicate the fraction III had the antibacterial activity against Staphylococcus aureus with the inhibition diameter of 10.7 mm and but no antibacterial activity against Escherichia coli. Identification of chemical compounds by GC-MS showed that the fraction III is dominated by compound fatty acids and phenolic groups. In conclusion, secondary endohpytes isolated from Jamblang plants branches contained predominantly fatty acid and phenol related compounds that could be responsible for its potent anti-microbial activity.

Title: Physicochemical and pharmaceutical properties of HEA-HEMA hydrogels
Biography:
Irina Ermolina has completed her PhD from Kazan Institute of Biochemistry and Biophysics, Russian Academy of Sciences in 1995, following by postdoctoral studies from Hebrew University of Jerusalem, Glasgow University and South Hampton University. Currently, she is a senior lecturer at De Montfort University, Leicester, UK, theaching the pharmaceutical technology, pharmaceutical material sciences and analytical techniques. She has published 45 papers in the peer reviewed journals and has been serving as a reviewer for several sceintific Journals.
Abstract:
Over the last years the hydrogels have attracted considerable attention due to their capability to be used for numerous pharmaceutical and biomedical applications (i.e. drug delivery systems, contact lenses and wound dressings). Hydrogels are swell able polymeric materials capable of imbibing a large amount of liquid and, therefore, a large amount of drug. Recently we have described novel cross-linked 2-hydroxyethylacrylate-co-2-hydroxyethylmethacrylate (HEA-HEMA) hydrogels with different co-polymer compositions synthesized by three-dimensional free-radical copolymerisation. The aim of the present work is to characterize the physicochemical and pharmaceutical properties of HEA-HEMA hydrogels, which potentially can be used as sustain drug delivery systems. The effects of the hydrogel composition (HEA/HEMA ratios) and liquid medium (aqueous PEG and glycerol solutions) on morphology, swelling and mechanical properties were examined using different analytical techniques. The molecular dynamics results for hydrogels were obtained by Broadband Dielectric Spectroscopy. The current study has been specifically focused on the analysis of the free/bound water redistribution in the hydrogels using thermo analytical techniques. Also the effect of different methods of sterilization was studied with respect to the stability of hydrogels. The pharmaceutical aspect of this study included the analysis of drug loading and release for the cases of low molecular weight drugs (riboflavin, ibuprofen) and proteins (lysozyme). The results show that HEA-HEMA hydrogels can be used as a sustain drug delivery system for both small drugs and bio macromolecules. The variation of the HEA-HEMA composition as well as liquid medium permits controlling the properties of hydrogels allowing producing the hydrogels with the drug release rate desired.

Abstract:
Paracetamol is widely used to treat pain and fever. However, it creates oxidative stress by causing the depletion of glutathion which leads to hepatic lesions and necrosis Clematis flammula is a plant widely used in folklore medicine in Algeria to treat inflammatory diseases. The hepatoprotective activity of this plant extracts were evaluated in vivo against paracetamol toxicity by the assessment of MDA levels superoxide dismutase and catalase activities. Histopathological analysis was equally carried out to confirm our results. Results demonstrated an increase in MDA levels (6.61±0.75 nmol/mg prot) and a decrease in the activities of superoxide dismutase (3.557±0.91 U/mg protein), catalase (2.41±0.49 U/mg protein), glutathione (2.45± 0.60 μmol/mg de protéine) in paracetamol (400mg/kg)-treated group (positive control), compared to negative control. Clematis flammula plant extracts, on the other hand, contributed at reducing MDA levels (2.34±0.47) and increasing the activities of superoxide dismutase (6.068±0.85 U/mmg protein), glutathion (17.80±2,42 μmol/mg proteins) and catalase (10.64±2,01 U/mg protein) at 100 mg/kg. Histopathological analysis confirmed the hepatoprotective activity of this plant against paracetamol toxicity.

Abstract:
Fluor is strongest electronegative element, a potent anion and cumulative toxin. This study was designed to evaluate the effect of resveratrol on serum total sialic acid (TSA) and lipid bound sialic acid in the rats chronically exposed to fluoride. The study was administered using 32 male Sprague Dawley rats weighing 200-250 g. Rats were divided into four groups (n=8/group). Group I comprised the control group, group II was treated with NaF (10 mg/lt/day), group 3 was treated resveratrol (50 mg/lt/day) and group IV was treated NaF+resveratrol for 90 days period. Total sialic acid (TSA) and lipid-bound sialic acid (LSA) were determined using spectrophotometric method. As a result of the analysis, It was seemed that LSA level compared with the control group increased in NaF group (p<0.05). On the other hand the resveratrol group was also significantly lower than the NaF group regarding LSA and TSA levels (p<0.05 and p<0.01 respectively). Whereas, the resveratrol + NaF group was significantly higher than the resveratrol group regarding TSA levels (p<0.05). Results from this study suggest that resveratrol may be partially effective in preventing the negative effects of fluorosis in male rats.

Abstract:
In humans, the enzyme N-acetyltransferase2 (NAT2), coded by NAT2 gene, is the main metabolizer of isoniazid, dapsone and hydralazine, used for the treatment of tuberculosis, leprosy and resistant hypertension, highly incident diseases in Brazil. We studied NAT2 in different Brazilian populations for these three diseases. In the first study, we showed the predominance of NAT2 slow acetylation alleles in Rio and Goias states. However, population from Rio showed a higher heterogeneity in NAT2 allele distribution and significant higher frequency of intermediate phenotype. We identified six new SNPs allowing characterization of seven new alleles. Further, we performed an in silico molecular modelling and structural protein analyses of NAT2. The results strongly indicates the direct involvement of the new SNP (152G>T-Gly51Val) in substrate recognition, SNP (203G>A-Cys68Tyr) in the modification of the catalytic site by the loss of a functional group and SNPs (458C>T, 578C>T, 683C>T and 838G>A) in enzyme degradation, all altering the acetylation activity to slow acetylation. In a subsequent study to evaluate the influence of CYP2E1, GSTT1, GSTM1 and NAT2 genotypes on isoniazid-induced hepatitis in TB patients, we found that only the NAT2 slow acetylation phenotype represented a risk factor for the occurrence of this outcome during TB treatment. In a more recent study, the influence of the acetylation phenotypes in anti-hypertensive effect of hydralazine in patients with RH was evaluated. Again, the predominance of slow acetylation phenotype was observed and only slow acetylators had significant blood pressure reductions after hydralazine use, however, with a high incidence of ADRs.

Abstract:
Parenteral insulin is one of the major therapeutic for patients with Diabetes Mellitus (DM) especially in Type 1, which often leads to patient discomfort and other problems due to the use of it within a certain period. Formulate insulin in oral dosage form is the main choice to resolve the issue. However, application of insulin orally encounters obstacles such as degradation by protease enzyme and poor insulin permeability of the gastrointestinal tract. One solution offered is insulin formulation into the nanoparticles form. In this study, nanoparticle formulation of insulin will use a combination of low molecular weight chitosan and pectin that serves to protect insulin from degradation and also enhance insulin absorption through the gastrointestinal mucosa. The aim of this study was to obtain the optimum formula of insulin nanoparticles that can be used as an alternative therapy for patient with DM. Preparation of insulin nanoparticles carried by ionic gelation method utilizing polyelectrolyte interaction between (-NH3+) of chitosan and (-COO-) of pectin to form nanoparticles that are compact and stable charge. Formula optimization was performed using Factorial Design 22 with Design Expert® 7.1.5 software. Concentration and pH of the pectin were used as factors, while the entrapment efficiency, particle size and polydispersity index were used as responses. The optimum formulas were further evaluated like zeta potential, particle morphology, profile spectra of FT-IR and in vitro release study. The obtained optimum formula consist of chitosan of 0.05% and 0.4% pectin (pH 5.0) with the mean entrapment efficiency of 63,59% ± 2,17, particle size of 228,3 nm ± 26,3, polydispersity index of 0,354 ± 0,042, zeta potential 49,40 mV ± 11,59, particle round and dark, polymer complexation was confirmed by FT-IR and release profile following the kinetics Korsmeyer-Peppas models with non-Fickian release mechanism on media HCl buffer pH 1.2 (n = 0.454) and Fickian release mechanism on PBS buffer pH 6.8 (n = 0.369). Nanoparticle insulin have AUC [(114,9917 ± 11,88) ng.menit/mL] higher than unmodified insulin [AUC = (67,8830 ± 2,17) ng.menit/mL] and PBS as negative control [AUC = (62,9713 ± 9,12) ng.menit/mL] with p < 0,05. Conclution from these results are insulin nanoparticle significantly improved insulin concentration in the blood serum higher than unmodified insulin per oral.

Title: Self-nanoemulsifying self-nanosuspension (SNESNS) for enhancing oral bioavailability of diacerein: Simultaneous portal blood absorption and lymphatic delivery
Time : 16:25-16:45
Biography:
Emad B. Basalious has completed his PhD and postdoctoral studies from Faculty of Pharmacy, Cairo University. He is an associate professor in department of pharmaceutics and Industrial pharmacy, Cairo University. He has published more than 20 papers in reputed journals. He is working as R&D technical consultant for several Egyptian pharmaceutical companies.
Abstract:
The application of self-Nano emulsified drug delivery system (SNEDDS) to improve bioavailability of diacerein (D) has been hampered by its large dose and limited solubility. This work aimed to prepare diacerein loaded self-Nano emulsifying self-Nano suspension (D-SNESNS) containing high drug load. DSNESNS was prepared by homogenizing D into MaisineTM-based SNEDDS that gave the highest drug solubility. D-SNESNS was evaluated for particle size, zeta potential and in vitro dissolution. Significant increase of D solubility was observed from D-SNESNS ( 309 mg/mL) than traditional SNEDDS (162 mg/mL) due to the spontaneous simultaneous formation of Nanoemulsion and Nano suspension (top–down approach). When exposed to water with mild agitation, the drug micro particles in D-SNESNS are temporarily surrounded by unsaturated aqueous layer (containing optimum concentrations of surfactant and co-solvent) that facilitates the erosion of the suspended drug particles into Nano sized ones. Nanoemulsion-based nano suspension (NENS) was confirmed using transmission electron microscopy and particle size analysis. D-SNESNS equivalent to 50 mg D exhibited complete and very rapid dissolution after 15 min in phosphate buffer pH 6.8 due to the existence of D as solubilized molecules inside Nanoemulsion globules and Nano sized suspended drug particles forming D-NENS. The relative bio availabilities of rhein from D-SNESNS in rats with normal and blocked chylomicron flow were about 210% and 164%, respectively in comparison to aqueous D suspension. The significant increase in the dissolution, portal absorption and lymphatic delivery of D propose that SNESNS could be promising to improve oral bioavailability of poorly water soluble drugs that have limited drug load in SNEDDS.

Abstract:
Gum is a dried exudate from stems and branches of acacia senegle linne willdenow and other related African species of acacia Family Leguminosae. It is a safe nontoxic material utilized in production of capsule shell compared to the gelatin. Capsule hardness and elasticity are influenced by changes in gum: water: plasticizer ratio. This study described the use of gum Arabic in the manufacturing of capsules, using water and plasticizer to fine-tune the elasticity. Hand pick gum Arabic grinded and treated by adding glycerine B.P, polyethylene B.P glycol, sorbitol and purified water in a ratio of 5:2:1 per volume in Wafrapharma industry. A flexible sheet was produced from the mucilage to confirm the formula reliability. Then after capsules shells were produced by process of dipping molds in the mucilage and let to dry. The influence of gum: water: plasticizer ratio on capsule formulation showed the difference in ratio of gum solution formula affects the elasticity degree of the sheet. When the quantity of the plasticizer is increased, the ratio of water: plasticizer decreased. Gum Arabic is a stable suitable natural material to be used in capsule shell production in Sudan. Both gum solution and plasticizer loading level were found to influence the initial rate of elasticity. Elasticity shown to be controlled by the added quantity of plasticizer.

CLL/SLL showed higher Bcl-2 and p53 gene expression than CLL. CLL patients showed one-third increase in Bcl-2 gene expression compared to healthy controls (p<0.05), and one-half decrease in p53 gene expressions (p<0.05). Bcl-2 gene expression was higher, particularly, for those who were treated with higher range of treatment courses and fludarabine cyclophosphamide rituximab (FCR) regimen. P53 gene expression reciprocally related with Bcl-2 and vice versa. In conclusion, the results of this study indicated that both of the anti-apoptotic Bcl-2 family members and additionally the tumour suppresser p53 may be thought-about as a result of the key choices of cancer and significantly contributes to the impact of current treatment modalities on cancer cells. Moreover, a marked role for p53 gene in the chlorambucil resistance in CLL is elucidated.

Abstract:
Tablets are the most widely used drug formulation. However, problems may arise in paediatric or elderly patients, whose swallowing functions are inferior. Mini-tablets (MTs) are considered easier to swallow than conventionally sized tablets (CTs). Although several trials suggest that MTs are the most acceptable oral formulation, reports comparing MTs with other tablet formulations and quantitative data for the ease of intake of a unit of several tablets are lacking. We aimed to evaluate the ease of taking MTs in comparison with that of other tablet formulations, as well as to evaluate the ease of taking different numbers of MTs. We prepared 4 types of tablets in 2 diameters (3 mm for MTs and orally disintegrating mini-tablets (ODMTs) vs 8 mm for CTs and orally disintegrating tablets, ODTs) and two formulations (MTs and CTs vs ODMTs and ODTs). Our randomized crossover trial in 18 healthy volunteers indicated that the visual analogue scale (VAS) score for the ease and amount of water required for intake of MTs was significantly lower than those of CTs. An ODMT required the least amount of water and smallest VAS score for ease of taking a tablet. The advantages of MTs, namely the ease of intake and the low amount of water required, were the most prominent for a unit comprising < 5 tablets. In conclusion, MTs could reduce the problems and risks associated with taking tablets and improve patient adherence, especially in paediatric and geriatric patients who have difficulty with taking CTs.

He has published over 60 top-notch Journal papers
Abstract:
On several levels, the dissolution and the permeability are related and should maintain a certain relationship between them. For instance, Tsume and Amidon (Mol Pharmaceutics 2010) have shown that the higher the permeability is, the more lax the dissolution criterion for granting a bio waiver can be. In this talk, regional-dependent intestinal permeability will be discussed, including dissolution aspects, as well as pathophysiological conditions. Permeability is location dependent, and pertains to each point throughout the gastrointestinal tract. A drug may exhibit significantly different intestinal permeability not only between the small and large intestine, but even within the small intestine, i.e. between the proximal jejunum and the distal ileum. The asymmetrical pH profile throughout the small intestine may be the underling mechanism for such segmental-dependent permeability of certain ionisable drugs. An asymmetrical expression pattern of different transporters throughout the intestinal tract may also cause such regional-dependent permeability. Asymmetrical intestinal enzymes expression may significantly influence the systemic bioavailability of a drug, although not necessarily affect the permeability. In these cases, rapid vs. sustained dissolving drug products may result unexpectedly different systemic drug levels. In conclusion, it is prudent to consider the intestinal permeability pattern when deciding on a certain dissolution profile.

Abstract:
A team of medical doctors in R.D.Congo, Jerome Munyangi and Michel Idumbo, have run randomized clinical trials in Maniema province with the participation of some 1000 malaria infected patients. The trials were run in conformity with the WHO procedures. For all the parameters tested herbal treatment was significantly better than ACTs. The efficiency was equivalent for Artemisia annua and Artemisia afra. More important even is the observation for the total absence of gametocytes after 7 days treatment with the herb. A tremendous hope for malaria eradication. The results have been communicated to the local health authorities, and to the Ministries of Health and Research in the RD Congo who were supportive of these trials. The draft of a paper is almost ready and will be submitted to a peer reviewed scientific journal. The large scale trials confirm those of Dr Constant Kansango in Katanga who had found in a trial with 44 Plasmodium falciparum infected patients that after 7 days of treatment with 20 gr of capsules containing a afra powder the gametocytes had completely disappeared, except for one patient. Artemisia afra does not contain artemisinin. The best explanation available is the high arginine content of Artemisia plants (see "Arginine, a deadly weapon against gametocytes" on malariaworld.org). In 2012 already Dr Saint-Hillier worked with capsules containing powdered leaves from the French Artemisia annua genotype with a content of 0.1 % artemisinin only. A total of 40 000 capsules containing one gram was administered, to adults, children, but also to neonates and pregnant women. The therapeutic effect of the capsules against fever and other clinical signs of malaria are always very fast. These results confirm results obtained by the association IFBV-Belherb and her partners in many small scale trials in several African countries. Therapeutic efficiency always was > 95% and prophylaxy was noticed and documented. The abstracts or peer reviewed papers of all these trials are available on request.

Title: Regucalcin protects HepG2 cells from Doxorubicin-induced apoptosis and Autophagy
Time : 15:50-16:05
Biography:
Noor has completed her master degree (MSc) in Histology on March 2010 from university of Duhok (Kurdistan Region Government of Iraq) and has published her master thesis as two papers in local university journal.

Abstract:
Regucalcin (RGN) is a cytosolic Ca2+-binding protein that was discovered in 1978 and is known to be a multi-functional protein involved in number of cellular processes including – calcium homeostasis by regulating Ca²+ binding protein activity such as Ca2+-ATPases, calmodulin kinase and PKC. This protein is mostly found in liver and kidney tissues. Furthermore, RGN also plays a defence role in Ca2+-mediated stress protection and apoptosis. Doxorubicin (DOX) is a potent anti-cancer drug that is used either in isolation or in combination with other drugs for treating variety of cancers. Several studies have shown that DOX induces p53 activation leading to apoptosis in both normal and tumour endothelial cardiomyocytes cells; by causing cytochrome c release from the mitochondria, resulting in caspase 3 activation and induction of apoptosis. Moreover, this drug has the ability to damage DNA by producing reactive oxygen species. A major problem of DOX treatment is that it is highly cardio- and hepato-toxic. In the current study we have investigated the molecular mechanisms of DOX-induced hepatic cell death and show that DOX can induce cell death in human HepG2 liver cells through a number of different mechanisms including; apoptosis, DNA damage and autophagy. However, necrosis does not appear to be involved in this process. Furthermore, over-expression of RGN in HepG2 cells was found to protect against the toxicity by DOX. Therefore increased expression of RGN in the liver could be a mechanism for protection against DOX-induced toxicity.

Abstract:
Mucin 1 (MUC1), as an oncogene, plays a key role in the progression and tumorigenesis of many human adenocarcinomas and is an attractive target in tumour immunotherapy. To develop an effective anti-tumour vaccine for the treatment of MUC1-expressing human tumours, our research group generated a recombinant MUC1-MBP fusion protein combined with Bacillus Calmette-Guerin (MUC1-MBP/BCG) anti-tumour vaccine, the repeated animal experiments demonstrated that MUC1-MBP/BCG anti-tumour vaccine not only induced the release of MUC1-specific antibody and a MUC1-specific Th1-dominant immune response, but also enhanced the cytotoxic T lymphocyte killing activity and the activation of macrophage and NK cells. Furthermore, the results from tumour-bearing nude mouse model revealed that MUC1-MBP/BCG anti-tumor vaccine significantly inhibited the growth of Lewis lung cancer, B16-MUC1 (MUC1+) and human breast cancer cells. To help move the vaccine into a Phase I clinical trial, the pilot production process and quality control standard of pharmaceutical research have been accomplished, and a majority of pharmacodynamics, pharmaceutical and toxicology pre-clinical studies have been accomplished as well. A pre-clinical toxicity evaluation that comprised of a single-dose acute toxicity study in mice, repeat-dose chronic toxicity and immunogenicity studies in rats, and pilot toxicity and immunogenicity studies in cynomolgus monkeys showed that treatment with the MUC1-MBP/BCG anti-tumour vaccine did not cause any organ toxicity. Collectively, these data are beneficial to move the MUC1-MBP/BCG anti-tumour vaccine into a Phase I clinical trial, and suggesting that MUC1-MBP/BCG vaccine is an attractive anti-tumour vaccine.

Abstract:
Treatment of Multiple Sclerosis (MS) has received substantial attention due to devastating symptoms, disability progression, mental health and cost of polytherapy. To investigate the effect of vitamin D supplementation as an add on to interferon beta on immunological, biochemical, radiological and clinical outcomes. Patients and methods: Double-blind, placebo-controlled, randomized study conducted in 54 MS patients on interferon beta at MS Center in Sulaimaniyah City, KRG-Iraq. Total of 43 patients completed the study. On vitamin D3 arm 13 patients received 10000 IU/day, 14 patients received 5000IU/day and on placebo arm 16 patients treated with placebo. Serum cytokines IL-2 and TGF-βâ‚ were measured. Modified Fatigue Impact Scale, cognition (MFIS), Expanded Disability Status Scale (EDSS), 9-hole peg test, 25-foot walk, lesion numbers at T2 and T1 enhancing lesion, brain atrophy, relapse occurrences were assessed twice for every patient at baseline and after six months of treatment. Results: after six months of treatment; serum vitamin D level significantly increased MFIS, EDSS and cognition function improved significantly, relapse rate reduced very significantly, TGF-βâ‚ serum level increased, IL-2 level and MS Functional Composite changed but not significantly, Gadolinium-enhancing lesions reduced significantly compared to placebo. Conclusions: Vitamin D deficiency is considered as both risk factor and consequences of MS. The optimum serum vitamin D level (40ng/ml) can be achieved faster by 10000IU vitamin D3/daily which can be considered as a loading dose, also favoured for prevention of relapse occurrences this level can be maintained by 5000IU vitamin D3/daily and keeping its therapeutic potential without causing hyperkalaemia.

Title: Identification of potentially conserved microRNAs in Calendula officinalis using homology-based approaches
Time : 16:35-16:50
Biography:
Maria Sala-Cîrtog is a third year PhD student at the University of Medicine and Pharmacy "Victor Babes", Timisoara (Romania) where she works as an Assistant professor in the Department of Biochemistry and Pharmacology.

Abstract:
MicroRNAs (miRNAs) are a group of small, noncoding endogenous RNA (21-25 nucleotides long) with an important role in gene expression regulation by targeting specific mRNAs in plants, animals and humans. To date, no miRNAs from marigold (Calendula officinalis), one of the best known medicinal plants, have been identified. This may be due to the lack of genome data regarding Calendula off. because the majority of available miRNA identification tools require a reference such as EST database or genomic sequence to discover novel miRNAs. Materials and Methods: - Certified plant material (Calendulae flos) and standard growth conditions - Plant small RNA isolation and extraction - Sequencing data analysis and plant miRNA identification Results: The cDNA libraries of two tissues from Calendula (petals and inflorescence) were prepared and small RNA-seq were conducted according to Illumina's protocols. To identify potential miRNAs, previously known miRNAs from Arabidopsis thaliana, Ricinus Communis, Linum Usitatissimum and Physcomitrella patens were downloaded from MirBase. The reference set miRNAs were compared against Calendula small RNA sequences using homology approaches. A total of 3 miRNAs, with 0 mismatches, (mir166a, lus-mir166e, ppt-mir894 and ath-mir8175), were identified based on their sequence complementarities. Conclusion: The potentially conserved miRNAs from Calendula were identified only in the inflorescence, which is the part used for medicinal purposes. This could lead to a better understanding of the relationship between plant exogenous genetic material and the changes in mammal upon oral ingestion.
