...the first accurate scientific paper about it was written in 1908 by Sir Archibald Garrod. Most people only think of humans in the case of albinism, but in reality, it affects humans as well as plants and animals. In plants, Albinism is the total or partial absence of chlorophyll. Because there is an inadequate amount of chlorophyll, photosynthesis is impaired. As a result, plants with albinism usually die at a young age. According to scientific authors Maya Kumari, Heather J. Clarke, Ian Small, and Kadambot H. M. Siddique, some environmental conditions like temperature, light, media composition, and culture conditions can play a role in determining the frequency of albino plant formation. Although environmental factors can sometimes play a role, genetic factors are the main determinants. Genetic studies in different crops show that it is a recessive trait governed by many loci. Because nuclear as well as chloroplast genomes affect albinism, incompatibilities between them is a likely cause of pigment defects in hybrid progenies (Kumari). In angiosperms large amounts of these incompatibilities are found. Unfortunately, there is no solution for albinism in plants. Although there is no solution, it has been defeated in some species through somatic hybridization and development of cybrids (Kumari). As in plants, albinism in animals, though rare, occurs when there no melanin produced. About one in ten thousand mammal births a year are albino. It is the most common in birds...

Juss (Meliaceae) is used traditionally in the treatment of malaria, intestinal worms, diarrhea, dysentery and venereal diseases. Despite the claim as an effective antidiarrheal remedy in both humans and animals, there is scarcity of documented scientific information of specific in vivo antidiarrheal test using extracts of this plant. The number of wet feces and the distance travelled by activated charcoal meal in rats orally given 300, 600 and 1200 mg/kg doses of aqueous and ethanolic extracts of the stem bark of K. senegalensis were evaluated in the castor oil induced diarrhea and gastrointestinal motility studies. The phytochemical constituents and acute toxicity test of the extracts...

...primary health care needs (Farnsworth et al., 1985). To date, 25% of modern medicines are derived from plants that have been used by traditional medical practitioners (Cragg and Newman, 2005). It is a fact that traditional systems of medicine have become a topic of global importance. African countries are at a stage where traditional medicine is considered more for its capacity to generate other medicine than for its own sake. In many cases research undertakings and the commercial use stemming from that research have always relied on information provided by the local communities and, in many instances, have hardly benefited from the research results (Rukangira, 2004) . In Africa, traditional healers and remedies made from plants play an important role in the health of millions of people. (Rukangira, 2004). Typically, studies on the medicinal plants such as Alstonia boonei have focused on the bioactivity of its chemical constituents, ethnobotany, pharmacology, and taxonomy. However, a comprehensive or systematic review on the plant is lacking. Furthermore, in much of the older literature concerning West Africa, the name Alstonia congensis has been erroneously used for Alstonia boonei. Consequently, this paper examined the effect of aqueous bark extracts of Alstonia boonei on the haematological parameters of male wistar abino rats. 1.2 LITERATURE REVIEW 1.2.1 Classification Alstonia comprises about 40 species and has a pantropical distribution. There are about twelve species of the...

It closely examines a selection of poems by Breyten Breytenbach, Dennis Brutus, Pascal Gwala, Wopko Jensma, Oswald Mtshali, Arthur Nortje, Cosmo Pieterse, Sipho Sepamla, and Wally Serote, among others. The body of the thesis discusses these poets' contributions to poetry about prison, exile, and township life. The thesis focuses on the struggle between various polical, racial, and cultural groups for hegemony over South Africa's poetic development. Such issues as language, ideology, and censorship are explored insofar as they in! .luence t:ne content and structure of the poetry. This body of poems, sadly, is little studied in North America. The thesis presents an introduction to and a survey of the major tendencies in South African poetry and, in part, attempts...

...Barack Obama Dreams from My Father “For we are strangers before them, and sojourners, as were all our fathers. 1 CHRONICLES 29:15 PREFACE TO THE 2004 EDITION A LMOST A DECADE HAS passed since this book was first published. As I mention in the original introduction, the opportunity to write the book came while I was in law school, the result of my election as the first African-American president of the Harvard Law Review. In the wake of some modest publicity, I received an advance from a publisher and went to work with the belief that the story of my family, and my efforts to understand that story, might speak in some way to the fissures of race that have characterized the American experience, as well as the fluid state of identitythe leaps through time, the collision of cultures-that mark our modern life. Like most first-time authors, I was filled with hope and despair upon the book’s publication-hope that the book might succeed beyond my youthful dreams, despair that I had failed to say anything worth saying. The reality fell somewhere in between. The reviews were mildly favorable. People actually showed up at the readings my publisher arranged. The sales were underwhelming. And, after a few months, I went on with the business of my life, certain that my career as an author would be short-lived, but glad to have survived the process with my dignity more or less intact. I had little time for reflection over the next ten years. I ran a voter registration project in...

EFSA Scientific Report (2009) 231, 1-107 © European Food Safety Authority, 2009 Review of the potential health impact of β-casomorphins and related peptides SUMMARY Proteins are a very diverse family of large organic compounds involved in many important biological processes. Following their enzymatic hydrolysis during food processing or digestion, proteins may release fragments from their primary amino acid sequence. These fragments are called peptides, and many of them are known to be physiologically active. The possible beneficial effects of bioactive peptides have attracted increasing interest in recent years. On the other hand, there are also reports suggesting that some food-derived peptides might adversely affect human health. Among these, β-casomorphin-7 (BCM7), a peptide sequence present in the milk protein β-casein, has been suggested to...
