African medicinal plants contain chemicals that may be able to stop the spread of cancer cells. This is the conclusion of researchers following laboratory experiments conducted at Johannes Gutenberg University Mainz (JGU). The plant materials will now undergo further analysis in order to evaluate their therapeutic potential. "The active substances present in African medicinal plants may be capable of killing off tumor cells that are resistant to more than one drug. They thus represent an excellent starting point for the development of new therapeutic treatments for cancers that do not respond to conventional chemotherapy regimens," explained Professor Thomas Efferth of the Institute of Pharmaceutical Sciences and Biochemistry - Therapeutic Life Sciences at Mainz University. For the past four years, Efferth and biochemist Dr. Victor Keute of the University of Dschang in Cameroon have been studying the active substances in African plants such as the giant globe thistle, wild pepper, speargrass, and Ethiopian pepper.
The find was announced by the University of the Witwatersrand, the National Geographic Society and the South African National Research Foundation and published in the journal eLife.">
International Journal of Quantitative and Qualitative Research Methods is run by the European Centre for Research, Training and Development, United Kingdom. The journal publishes outstanding academic, theoretical and methodological articles relating to quantitative, qualitative and research in professional and service settings. The journal covers issues addressed by researchers within academic and independent research organizations in different areas. The scope of the journal focuses on the on-going and emerging methodological debates across a verities of methods. These include mixed and comparative methods relating to philosophical, theoretical, ethical, political and practical issues. It is also an international medium for the publication of social research methodology and practices across a wide range of disciplines and avenue for researchers in different sectors to consider and evaluate methods as these relate to research practice. It also publishes book reviews of potential interest to readers. The journal is published in both print and online versions. The online version of the journal is free access and downloads.
International Journal of African Society, Cultures and Traditions (IJASCT) is run by the European Centre for Research Training and Development, United Kingdom. IJASCT publishes original contributions that relate to African society, cultures and traditions drawn from African continent. The scope of the journal includes papers in broad theoretical and methodological contexts which stress, but are not limited to, cultures and traditions in African society. It also publishes book reviews of potential interest to readers. Papers submitted to this journal must be original, and are not considered in any other journal. The journal is published in both print and online versions. The online version of the journal is free access and downloads.
He noted that the Department of Health has more interest in this development than anyone else in the world, as 30% of all people on treatment in the whole world are in South Africa under the department. He also thanked people living with HIV and Aids, who willingly participated in research studies. “Your selflessness has been helping the world to better understand the HIV virus so that we can prevent transmission and find the cure.”
The research was conducted by CAPRISA consortium, including scientists from Wits University, the National Institute for Communicable Diseases (NICD) in Johannesburg, the University of KwaZulu-Natal and the University of Cape Town.
The study, published in the scientific journal, Nature, describes how the research team found and identified the antibodies in her blood and then duplicated them by cloning the antibodies in the laboratory.
The discovery of how a KwaZulu-Natal woman’s body responded to her HIV infection by making potent antibodies, called broadly neutralising antibodies, was reported on Monday by the Centre for the AIDS Programme of Research in South Africa (CAPRISA). The consortium is made up of AIDS researchers jointly with scientists from the United States.
Just over a year ago, the same team of South African researchers reported in Nature Medicine (also part of the Nature group of journals) on their discovery relating to two other KwaZulu-Natal women, that a shift in the position of one sugar molecule on the surface of the virus led to the development of broadly neutralising antibodies against HIV.
This article was published in the Journal of Speech Language and Hearing Research in June 2008, to report the findings of a research conducted on the effects of parent-child interaction therapy approach (PCIT) on children who stutter.

In their latest of a total of eight publications produced to date, the research team reports that four naturally occurring benzophenones can prevent the proliferation of the tested cancer cell lines, including multi-drug resistant strains. "The benzophenones investigated are potentially cytotoxic substances that need to be more extensively investigated with the aim of developing new cancer drugs that are effective against susceptible and resistant cancers", claims the article recently published in the scientific journal .
