Abstract
BACKGROUND Small cell vaginal carcinoma is a very rare gynecological cancer and treatments including chemo- and radiotherapy have had limited success. CASE REPORT We report the case of a 37-year-old female, where intensive treatment with the combination of paclitaxel, carboplatin, irinotecan, and camptothecin with and without irradiation did not avoid metastasis of the tumor and the death of the patient. In an attempt to develop a strategy for individualized tumor therapy, we performed immunohistochemistry of 19 cancer-related proteins using a biopsy sample. Strong expression was observed for glutathione S-transferase P1 (GSTP1), epidermal growth factor receptor (EGFR), inducible nitric oxide synthetase (iNOS), nuclear factor kappa B (NF-κB), the oncogene c-MYC, vascular endothelial growth factor (VEGF), and the proliferation marker Ki-67. Intermediate expression was found for the oncogene SRC, β-catenin, and the viral E7 protein. We then performed virtual drug screening with PyRx and molecular docking with AutoDock 4.2.6 by using the three-dimensional structures of these proteins and a chemical library of 1,577 FDA-approved drugs, in a drug repurposing approach. The top 15 compounds were either approved anticancer drugs or drugs used to treat non-malignant diseases. These compounds were bound with comparable or even higher affinity to the targets compared to control inhibitors. Several of these compounds were bound with high affinity to more than one of these target proteins, further supporting the drug repurposing concept. CONCLUSION These drugs might offer additional opportunities to reach treatment responses. This approach of individualized tumor therapy might be theoretically not only applicable for small cell vaginal carcinoma but for other tumor entities as well.

Abstract
BACKGROUND Practices of biopiracy to use genetic resources and indigenous knowledge by Western companies without benefit-sharing of those, who generated the traditional knowledge, can be understood as form of neocolonialism. HYPOTHESIS The One-World Medicine concept attempts to merge the best of traditional medicine from developing countries and conventional Western medicine for the sake of patients around the globe. STUDY DESIGN Based on literature searches in several databases, a concept paper has been written. Legislative initiatives of the United Nations culminated in the Nagoya protocol aim to protect traditional knowledge and regulate benefit-sharing with indigenous communities. The European community adopted the Nagoya protocol, and the corresponding regulations will be implemented into national legislation among the member states. Despite pleasing progress, infrastructural problems of the health care systems in developing countries still remain. Current approaches to secure primary health care offer only fragmentary solutions at best. Conventional medicine from industrialized countries cannot be afforded by the impoverished population in the Third World. Confronted with exploding costs, even health systems in Western countries are endangered to burst. Complementary and alternative medicine (CAM) is popular among the general public in industrialized countries, although the efficacy is not sufficiently proven according to the standards of evidence-based medicine. CAM is often available without prescription as over-the-counter products with non-calculated risks concerning erroneous self-medication and safety/toxicity issues. The concept of integrative medicine attempts to combine holistic CAM approaches with evidence-based principles of conventional medicine. CONCLUSION To realize the concept of One-World Medicine, a number of standards have to be set to assure safety, efficacy and applicability of traditional medicine, e.g. sustainable production and quality control of herbal products, performance of placebo-controlled, double-blind, randomized clinical trials, phytovigilance, as well as education of health professionals and patients.

Abstract
BACKGROUND Biopiracy mainly focuses on the use of biological resources and/or knowledge of indigenous tribes or communities without allowing them to share the revenues generated out of economic exploitation or other non-monetary incentives associated with the resource/knowledge. METHODS Based on collaborations of scientists from five continents, we have created a communication platform to discuss not only scientific topics, but also more general issues with social relevance. This platform was termed 'PhytCancer -Phytotherapy to Fight Cancer' (www.phyt-cancer.uni-mainz.de). As a starting point, we have chosen the topic "biopiracy", since we feel this is of pragmatic significance for scientists working with medicinal plants. RESULTS It was argued that the patenting of herbs or natural products by pharmaceutical corporations disregarded the ownership of the knowledge possessed by the indigenous communities on how these substances worked. Despite numerous court decisions in U.S.A. and Europe, several international treaties, (e.g. from United Nations, World Health Organization, World Trade Organization, the African Unity and others), sharing of a rational set of benefits amongst producers (mainly pharmaceutical companies) and indigenous communities is yet a distant reality. In this paper, we present an overview of the legal frameworks, discuss some exemplary cases of biopiracy and bioprospecting as excellent forms of utilization of natural resources. CONCLUSIONS We suggest certain perspectives, by which we as scientists, may contribute towards prevention of biopiracy and also to foster the fair utilization of natural resources. We discuss ways, in which the interests of indigenous people especially from developing countries can be secured.

Abstract
BACKGROUND While cancer epidemiology is well-investigated in developed countries, the cancer burden in Africa is less well documented. We provide cancer statistics of 33,201 patients from all Sudan diagnosed at the Radiation and Isotope Centre in Khartoum (RICK). This hospital covers approximately 80% of patients with cancer in Sudan and is, therefore, considered representative for the situation in this country. MATERIALS AND METHODS Data from 2009-2013 were collected at RICK. Cancer diagnoses were made by standard pathological and radiological methods. Epidemiological data were categorized by age, gender, resident state, marital status etc. and subjected to statistical analyses by SPSS 21v. RESULTS The cancer prevalence rate per year was 5,000-7,000 among adults and 300-400 among children, with increasing tendency for adults. Male:female ratios were 1:1.18 for adults and 1.46:1 for children. The five most frequent tumour types were breast cancer, leukaemia, prostatic carcinoma, lymphoma and colorectal carcinoma in adults and leukaemia, lymphoma, eye tumours, sarcoma and brain tumours in children. Remarkably, the median age of cancer diagnosis was 10-20 years higher in men than in women, mainly due to earlier onset of gender-related tumours in females (cancer of breast, cervix, or ovary) than in men (prostatic carcinoma). Chronic myeloid leukaemia was the most frequent haematopoietic malignancy in adults and acute lymphoblastic leukaemia in children. Comparing cancer cases with population numbers of Sudanese states, Northern Sudan, River Nile and Khartoum revealed up to 8-fold higher cancer incidence rates than Al Gedarif, Southern Dafur and Blue Nile. The other states had intermediate incidence rates. Interestingly, oesophageal carcinoma occurred proportionally more frequently in Kassala (rank 3) than in the entire Sudan (rank 7) or other states. CONCLUSION This is the largest survey on cancer burden in Sudan. It may serve as basis for governmental programmes for assessing risk factors, improving cancer prevention (e.g. by educational and vaccination programmes) and cancer therapy in the future.

Abstract
Multidrug resistance is a prevailing phenomenon leading to chemotherapy treatment failure in cancer patients. In the current study two known cytotoxic pseudoguaianolide sesquiterpene lactones; neoambrosin (1) and damsin (2) that circumvent MDR were identified. The two cytotoxic compounds were isolated using column chromatography, characterized using 1D and 2D NMR, MS, and compared with literature values. The isolated compounds were investigated for their cytotoxic potential using resazurin assays and thereafter confirmed with immunoblotting and in silico studies. MDR cells overexpressing ABC transporters (P-glycoprotein, BCRP, ABCB5) did not confer cross-resistance toward (1) and (2), indicating that these compounds are not appropriate substrates for any of the three ABC transporters analyzed. Resistance mechanisms investigated also included; the loss of the functions of the TP53 and the mutated EGFR. The HCT116 p53-/- cells were sensitive to 1 but resistant to 2. It was interesting to note that resistant cells transfected with oncogenic ΔEGFR exhibited hypersensitivity CS toward (1) and (2) (degrees of resistances were 0.18 and 0.15 for (1) and (2), respectively). Immunoblotting and in silico analyses revealed that 1 and 2 silenced c-Src kinase activity. It was hypothesized that inhibition of c-Src kinase activity may explain CS in EGFR-transfected cells. In conclusion, the significant cytotoxicity of 1 and 2 against different drug-resistant tumor cell lines indicate that they may be promising candidates to treat refractory tumors.

Abstract
BACKGROUND Cancer is a complex disease with multiple genetic and epigenetic alterations. Since decades, the hallmark of cancer therapy is chemotherapy. Cytotoxic drugs erase rapidly dividing cells without sufficient differentiation between normal and cancerous cells resulting in severe side effects in normal tissues. Recently, strategies for cancer treatment focused on targeting specific proteins involved in tumor growth and progression. The present study was designed to investigate the cytotoxicity of 65 crude extracts from 35 Sudanese medicinal plants towards various cancer cell lines expressing molecular mechanisms of resistance towards classical chemotherapeutics (two ATP-binding cassette transporters, ABCB1 (P-glycoprotein) and ABCB5, tumor suppressor p53, epidermal growth factors receptor (EGFR). And the aim was to identify plant extracts and isolated compounds thereof with activity towards otherwise drug-resistant tumor cells. METHODS Cold maceration was performed to obtain crude extracts from the plants. The resazurin assay was used to determine cytotoxicity of the plant extracts. Microarray-based mRNA expression profiling, COMPARE, and hierarchical cluster analyses were applied to identify, which genes correlate with sensitivity or resistance to ambrosin, the main constituent of the most active extract Ambrosia maritima. RESULTS The results of the resazurin assay on different tumors showed that Lawsonia inermis, Trigonella foenum-graecum and Ambrosia maritma were the most active crude extracts. Ambrosin was selected as one active principle of A. maritima for microarray-based expression profiling. Genes from various functional groups (transcriptional regulators, signal transduction, membrane transporters, cytoskeleton organization, chaperones, immune system development and DNA repair) were significantly correlated with response of tumor cell lines to ambrosin. CONCLUSION The results revealed cytotoxicity and pharmacogenomics studies of Sudanese medicinal plants provide an attractive strategy for the development of novel cancer therapeutics with activity towards cell lines that resistance to established anticancer agents.

Abstract
The effect of an ethanol extract of Commiphora myrrha oleo-gum resin on hematological and pathophysiological parameters of male Wistar rats was examined. The extract was given daily for 2 w at 1000 mg/kg bw per os, 500 mg/kg bw i.m. or 250 mg/kg bw i.p. Depression, huddling together, soft feces, jaundice, ruffled hair, hepatonephropathy, hemorrhagic myositis and patchy peritonitis (at the injection site) and death were accompanied by increases in serum ALP and ALT activities, bilirubin, cholesterol and creatinine concentrations, and decreases in total protein and albumin levels, and macrocytic anemia and leucopenia. When administered at 500 mg extract/kg bw/d per os or 250 mg extract/kg bw/d i.m. for 2 w it was not lethal, and when given daily for 1 w the effect was less marked.
