Breat cancer is a worldwide problem, accounting for 13,7% of cancer related deaths and 22,9% of all cancer cases. In addition, resistance to current endocrine therapies and/or side effects of current therapies provides impetus for the discovery of alternative drug leads. Several lines of evidence suggest that the Cyclopia extract, SM6Met, has potential as chemopreventative and/or chemotherapeutic agent for breast cancer in that it displays some of the attributes required for an ideal SERM and may behave as an intelligent mixture that could hold high potential amongst others targeting endocrine resistant breast cancer. Furthermore, formulation of a Cyclopia nutraceutical with known composition and proven efficacy in breast cancer prevention and/or treatment could provide African patients with a formulation at reduced cost that may display reduced side-effect in comparison to conventional therapies and/or could be used in adjuvant setting.
Mrs. Louw’s current research focuses on phytoestrogenic compounds found in extracts of Cyclopia, a plant indigenous to South Africa that is used to prepare an herbal tea. As indicated, one specific extract, SM6 Met, holds potential for the prevention and/or treatment of breast cancer in that it displays several desirable estrogenic traits. She wishes to continue her research taking it to the next level by identifying the specific compound(s) in the SM6Met conferring the desirable estrogenic attributes and establishing whether synergism and multi target mechanisms of action are of relevance. To achieve the above aims would require the evaluation of many extract and/or compounds at several concentrations. Prof. Louw will be doing this research at the Spanish National Cancer Research Centre (CNIO, www.cnio.es).

ASTER TSEGAYE ABEBE
Dr. Tsegaye argues that Ethiopia is among sub Saharan African countries where the mother to child HIV transmission is still high. According to data from the Federal Ministry of Health the number of HIV positive pregnant women in 2014 was 32.807 of whom 19.885 mothers where on antiretroviral therapy (ART) for prevention of mother to child transmission (PMTCT). The percentage of HIV-positive pregnant women who received antiretroviral (ARV) therapy or prophylaxis to prevent Mother-to-Child Transmission (MTCT) of HIV has significantly improved from 43% in 2013 to 60.6% in 2014.
Although HIV infection in children presents many aspects in common with that of adults the immunological immaturity of children in the first months of life and the difficulty of diagnosis in this period confer some particular characteristics that differentiate it from that found in the adult population. The transmission route in children is principally vertical; either it can occur during pregnancy, during labor and delivery, or after birth through breast feeding. Approximately 15-40% of children born to HIV-positive mother become infected with the virus. As the disease progression in children who acquire HIV infection from their mothers is more rapid in Africa than in developed countries, probably since African children are exposed to early and multiple infections with high rates of malnutrition and micronutrient deficiencies and have limited access to health care. Thus, studying the magnitude and assessing the clinical and viro-Immunological characteristics of infants and children born to HIV infected mothers will contribute to designing appropriate intervention strategies and reduce mother to child transmission of HIV. This is in the subject Dr. Tsegaye plans to research at the Carlos III Health Institute (ISCIII, www.isciii.es).
Dr. Tsegaye was born in Nazareth, Ethiopia and was trained as a Biologist at Addis Ababa University (AAU), in 1995 she got her Master’s Degree in Zoology at the same University. In 2000 studied at the Leiden University Medical Center (Netherlands) and in 2004 got her PhD in Immunology. Currently is Associate Professor at Department of Medical Laboratory Science, in the College of Health Science, Addis Ababa University. She is also interested in women issues and plays a leading role in the newly established society called Society of Ethiopian Women in Science and Technology (SEWIST) for which she is serving as Vice-President.

Dr. Ebel teaches Molecular Biology at the Institute of Biotechnology of Sfax in Tunisia. She works in a new project aiming to investigate the role of a gene in a durum wheat. This gene acts putatively at the interface of stress perception and cell cycle to maintain cell division in meristematic tissues despite adverse conditions. She will research this issue at the Spanish National Centre for Biotechnology (CNB, www.cnb.csic.es), aiming at the socio-economic impact this study can have in agricultural politics for semi-arid countries such as Tunisia.
Dr. Ebel is Assistant Professor at the Institut Supérieur de Biotechnologie de Sfax since 2004. She teaches Molecular Biology and Genetic Engineering, Plant Biotechnology and Microbial Genetics. She is an active member of the group “Plant Protection and Improvement” (under direction of F. Brini) studying plant responses to abiotic stresses in cereals.
She holds a DEA from the University of Strasbourg obtained in 1966 for her studies in Trans-splicing in Euglenas. In 2000 she got her PhD at the same University for her research in the laboratory of Prof. Thomas Boller at the Friedrich Miescher Institute in Basel, Switzerland on the “Role of Calcium in elicitor-mediated signal transduction pathways.” Dr. Ebel has done post-doctoral research in the Laboratory of Prof. Wilhelm Gruissem at the Federal Institute of Technology (ETH) Zurich in the area of the Function of Retinoblastoma-related protein RBR1 in Arabidopsis thaliana.
Dr. Ebel has published a number of articles in well-known journals such as Current Genetics, in 1999 and 2000 on “Trans-splicing and cis-splicing in the colourless” and “Characterization of trans-splicing in Euglenoids.” Other Journals such as Febs Letters, Journal of Plant Physiology, Nature, Plant Moleular Biology Reporter have her work published.

Chini and R. Solano (CNB, Madrid, Spain). In 2013 she got a grant from the French Institute in Tunisia entitled “Sejour Scientifique de haut Niveau.” Also from 2009 to 2011 she participated in a Spanish-Tunisian program entitled “Importance of protein phosphorylation in the function of the wheat DHN5 protein” with the team of M. Pagès (CSIC, Barcelone, Spain).
Along with a number of oral and poster presentation in different European and Arab countries (Switzerland, Austria, Spain, France, the Netherlands and Tunisia) she teaches at the Institute of Biotchnology of Sfax and supervises PhD theses and Master theses.
Her proposal to work at the Spanish National Centre for Biotechnology (CNB) is a research that will continue her research topic: improve wheat productivity by a better control of plant cell cycle, growth of biomass gain despite constantly changing environmental conditions. The project has a potentially high socio-economic impact for future agriculture policy in semi-arid countries like Tunisia. Therefore, facing the dramatic climatic changes, a still growing world population and a strong demand for raisin crop production, the development of cereals producing equivalent biomass under adverse conditions may contribute for sustainable agriculture.
Mrs. Niang is a Senegalese and a post-doctoral student in Laboratoire de Physique de l’Atmosphere et de l’Ocean Simeon-Fongang (LPAO-SF). She studied at Cheikh Anta Diop University of Dakar (UCAD) where she got her Bachelor Degrees and her two Master’s Degrees. In 2015 she earned her PhD in a program of the Federal University of Technology AKure (FUTA) in Nigeria and Laboratoir de Physique de l’Atmosphere et de l’Ocean Simeon Fongang LPAO-SF in Dakar in the Cheikh Anta Diop University. The title of her dissertation was: “Influence of the Madden-Julian oscillation on Rainfall Variability over West Africa at Intraseasonal timescale.”
Dr. Niang will be working at the Institute of Mathematical Sciences (ICMAT, www.icmat.es). Her main interest lays in pursuing a scientist researcher career focusing in the intraseasonal tropical variability with a focus on the West African Monsoon (WAM) variability. Her research aims to identify and understand the influence of large scale atmospheric drivers on West African rainfall and features; and investigate the associated dynamical processes at intraseasonal timescale with dynamical modeling approach.
Dr. Niang argues that West Africa constitutes a particular region of the world thar is characterized by an alternation between dry boreal winter and summer rainy conditions associated with the West African Monsoon which provides most of the rainfall over the region. Rainfall shows variability at a wide range of time scales: from the decadal droughts during the 1970x and 1980s, which led to widespread famine, to intraseasonal fluctuations, which are relatively well documented and have been the focus of considerable research. The work she proposes is in the framework of a previous collaboration with the TROPA-UCM-IGEO in the Universidad Complutense de Madrid, where we analysed the eventual impact of MJO (Madden-Julian Oscillation) on West African rainfall variability by analyzing the skills of AMIP (Atmospheric Model Intercomparison Project) models in stimulating the main characteristics of the MJO.
This project will continue this resear line by attempting a deeper understanding of transport processes in this setup. The aim of this study is to identify the sources of the moisture uptaken along the African jetys by means of Langrangian techniques. The main goal is exploratory: Other Langrangian techniques not previously employed in this context will be proposed in an interdisciplinary collaboration with ICMAT, IGEO and UCM. In this sense this work will be a first attempt to perform a comprehensive analysis of moisture sources that affect the major precipitation over West Africa during the boreal summer. The Langrangian method will lead in quantifying moisture recycling and the source-sink relations between evaporation and precipitation by tracking mainly the evaporation minus precipitation, zonal wind and specific humidity changes. Second the investigation will attempt to check any elationship between the moisture transported by the jets and the MJO evolution.
This research will have a clear impact over West Africa by providing on the one hand a better understanding of the relationship between MJO and moisture associated to the WAM at interseasonal timescale.On the other hand it will give also a potential use of the MJO events to predict moisture flux anomalies associated to the WAM however pointing to a potential benefits skilful extended range forecast in advance of the regional-scale rainfall spells over West Africa. This potential prediction are of vital importance for water resources and agriculture, which is mainly rain-fed and, therefore, highly dependent on rainfall.
Dr. Niang has published articles and participated in workshops in Ghana, Ivory Coast Toulouse and Boulder (Colorado). Dr. Niang lives in Dakar and speaks French, English and Spanish.

JELAN MOFEED EL-SAYED
Dr. Mofeed El-Sayed is an Egyptian, Associated Professor of Environmental Pollution (Microbiology) at the Faculty of Fish Resources, Suez University. She has a large experience in identification of both marine and fresh water algae, the use of algae as bioindicators for pollution, biomarkers and innovative techniques in intensive aquaculture of marine algae in order to increase productivity in the field of aquaculture and energy production. She is interested in the field of biotechnology and algae, especially in the field algae identification and its relationship to pollution and also adding some desirable characteristics using genetic engineering, subject she plans to study at the Centro Nacional de Biotecnologia.
Her interest lays basically in classifying the un-identified marine algae present in Suez Canal, Egypt. The high level of expertise and time consuming process needed to identify them means a loss in biodiversity due to this lack of identification. Marine algae are cultivating all over the world and are considered to be endangered, and this has lead to the development of large illegal trade in marine algae products.
The development of the polymerase chain reaction (PCR) has had a huge impact on the study of aDNA. However as aDNA fragments are not only small in size but may also be covered or coated with inhibitors resulting from poor preservation, it is necessary to remove these inhibitors to avoid false positive results. In order to assign an unknown DNA sequence to a species: first a reference DNA sequence of the same species is needed and secondly a genetic study to determine the intraspecific DNA sequence variation of the species. The main aim of her research at the Spanish National Centre for Biotechnology (CNB, www.cnb.csic.es) will be to develop a standard technique for DNA extraction using PCR amplification. It is hoped that this will enable species identification of marine algae species collected from Suez Canal. She also plans to develop the necessary tools in algae molecular and synthetic biology for accumulation of desired products, the production of algae biomass (including sequestration of CO2 from flue gases), use of cyanobacteria for the production of bio-photovoltatic panels.
Dr. Mofeed studied at Manssoura University (Egypt) and obtained her B.Sc in Microbiology 1995; in 2001 she presented her Thesis at the same University and in 2006 she earned her PhD with her thesis: “Ecological studies on the dynamics on the biodiversity in the Delta Region of the River Nile.” Her research interests are: Water pollutants, environmental toxicology, microbiology, monitoring of the effect of pollution on algal distribution and the study of “biomarkers” (molecular and biochemical responses to toxicants and pollution). She also is interested in the use of DNA barcoding technique to identify some algae species, residues of some pollutants like pesticides and heavy metals in water and plants, biodegradation of pollutants in water, research of bioaccumulation and biological effects of pollutant in the organisms and genome-wide transcription factor profiling background.
Dr. Mofeed is also the Principal Investigator (PI) in the project entitled “Innovative techniques in intensive aquaculture of marine algae in order to increase productivity in the field of aquaculture and energy production”, funded by the Egyptian Academy of Scientific Research. She is the PI of the project “Support and develop effective educational program for marine fisheries,” and co-researcher in “Biochemical biomarkers in algae Scenedesmus obliquus exposed to heavy metals (Cd,Cu and Zn) funded by de Deanship of Scientific Research of King Abdulaziz University (Saudi Arabia).
Jelan Mofeed Elsayed has published a number of articles in well-known scientific Journals in Egypt and other countries, she has also given conferences in International gatherings in Thailand, Egypt and France.
She teaches many courses at the university and is deeply involved in the research programs. She is also a member of a number of organizations related to her interests.
Dr. Jelan Mofeed lives in Manssoura, Egypt. She speaks Arabic (native language) and English.

In Spain, Dr. Matoetoe will be working at the Institute of Photonic Sciences (ICFO, www.icfo.eu). For the last five years she and her team have been studying remediation and detection of trace pollutant in the environment. Among these they assessed potential of biometallic nanomaterials for detection of neverapine. However, detection limits and matric effects were problematic. Only the amperometric detection was used. Dr. Matoetoe believes that it would be ideal, in her research, to evaluate impedance, as well as using metal organic frameworks (MOF) which can minimize the effects of matrixes especially if porous forms are used. She intends to work in the fruition of the biosensor. The nanosensors will be tests for screen drug efficacy as well as water quality in the country which has seriously become the issue. The sensor fabrication can easily be automated using screen printing techniques as a result mass production can follow optimization.
Her objectives are: Synthesis, spectroscopic and electrochemical characterization of metal nanoparticles with fabrication in porous metal-organic frameworks (MOFs). Design and optimization of the electrochemical nanobiosensor using MOF on glassy carbon electrodes. The following techniques will be assessed: cyclic voltammetry (CV), square wave voltammetry (SW#V), differential pulse voltammetry, electrochemical impedance spectroscopym (EIS) and scanning electrochemical microscopy (SCEM). Mofphological effects will be evaluated using transmission electron microscopy (TEM), x-ray (EDX), Fourier transform infra-red spectroscopy (FTIR) and spectroelectrochemistry. Application of the nanobiosensors in the screening and detection of selected ARVs in anti-HIV combinational therapy formulations.

Dr. Moloto is a South African senior researcher at the University of Witwatersrand in South Africa. She studied at the University of Zululand where she got her Bcs and her Master’s Degree (Cum Laude). In 2011 she obtained her PhDat the University of Witwatersrand (South Africa). She was a Professor at the University of Johannesburg and a candidate researcher at the Council for Scientific and Industrial Research (CSIR) in Stellenbosch (SA). From 2014 she is a Professor and senior researcher at the University of Witwatersrand.
In the Institute of Photonic Sciences (ICFO, www.icfo.eu), Dr. Maloto will focus on the synthesis and characterization of metal chalcogenide nanocrystals for application in solar cells. This research can be divided into three sections with the synthesis and characterization of materials in the pinnacle and connecting the other two areas: application in electronic devices and application as bio labels. This research area involves the synthesis of various types of inorganic semiconductor nanocrystals ranging from II-VI (CdS, CuS, CuSe, ZnO etc.) to IIIV (InN, GaN) nanocrystals, 2D layered nanostructures (InS2, MoS2, WS2 etc.) as well as ternary (CIS, CISe, CITe etc.) and quaternary nanocrystals (CIGS, CZTS etc.). Hybrid nanostructures such as polymer nanocomposites, core-shells and quantum dots (QDs) decorated carbon nanotubes are also undertaken. Semiconductor materials are attractive materials for use in optoelectronic devices mainly as a result of their tuneable absorption and photoluminescence spectra, large surface area (because of their small size), their adaptability, their ability to generate multiple excitons as well as their capability of hot carrier injection from excited state i.e. by minimizing energy loss during thermalization of excited state.
Semiconductor nanocrystal solar cells are projected to achieve higher efficiency than silicon based solar cells while reducing the cost of (1) each kilowatt of electricity produced, (2) the raw materials and (3) the processes used to convert the raw materials into functional cells. Semiconductor nanocrystals in solar cells are very versatile and can be used in various types of photovoltaic cells, such as infrared photovoltaics, multi-exciton generating solar cells, quantum dot dye sensitized solar cells (QDSSC), rainbow solar cells, intermediate band solar cells, and luminescent solar cells.
The streng within her group is primarily on the synthesis and characterization of materials with the application in solar cells fairly a new area that needs to be further developed. Hence the aims and objectives of the fellowship will be to study the electrical properties of metal chalcogenides synthesized in the lab, to fabricate solar cells of different architecture using materials synthesized and to use various techniques for characterization and understanding of solar cells.
Dr. Moloto’s research interests are: quantum dots, inorganic nanostructures, hybrid nanostructures and polymer nanocomposites, solar cells and gas sensors, bio-labels and chemical sensors. She also is supervisor of a number of PhDstudents at Wits and co-supervisor in other South African Universities. She is also supervisor of Master’s Degree students. Her teaching activities and interests are: inorganic chemistry, nanochemistry, materials chemistry, coordination chemistry, organometallic and materials characterization.
