Abstract: Ethiopia is claimed as the likely center of origin for okra [Abelmoschus esculentus (L).Moench], but few studies were conducted to assess the diversity of the crop in the country. Moreover, no attempt has been made to assess the diversity of okra genotypes for seed yield and related traits though the crop is known for the production of quality edible oil. Therefore, this study was conducted with the objectives of assessing genetic variability among okra genotypes for seed yield and...
Abstract: The ABO and Rh blood groups are the most important blood groups despite the long list of several other blood groups discovered so far. The ABO and Rh blood groups varies worldwide and are not found in equal numbers even among ethnic groups. Therefore, the objective of the study was to estimate phenotypic, genotypic and allelic frequencies of ABO and Rh blood groups among students of Oromo, Amhara and Gurage ethnic groups in Geresu Duki preparatory school in Woliso town, Oromia, Eth...
Abstract: The four blood types are known as A, B, AB, and O. Blood type A contains A antigen on the surface of red blood cells and B antibody on blood plasma. Type B blood contains the reverse combination. Serum of blood type AB contains neither antibody, but red cells in this type of blood contain both A and B substances. In type O blood, neither substance is present on the red cells, but the individual is capable of forming antibodies directed against red cells containing substance A nor B...
Abstract: The frequency of ABO and Rh-D blood group vary ethnically, geographically and from one population to another. Information on the distribution of ABO and Rh- D blood group is essential in relation to blood transfusion, clinical studies, genetic research and other health determination. There is no previous study reported the distribution of ABO and Rh- D blood groups in the population of Bordodde town. The aim of the present study was to determine Frequency of ABO and Rh (D) Blood Gr...
Abstract: The Knowledge of distribution of ABO and Rh blood groups is helpful for effective management of blood banks and safe blood transfusion services. The frequency of these blood groups varies worldwide and may not be found in equal numbers even among ethnic groups. The aim of this study was to find out the distribution of ABO and Rh (D) blood groups among students attending Chorora Secondary and Preparatory school in West Hararghe Zone Oromio Ethiopia. The study was designed from Janua...
Abstract: The purpose of this study was to identify grades 10 and 11 students’ misconceptions about cell biology and cell division, their sources and levels and to evaluate the effectiveness of biology teachers’ instructional methods to remediate students’ misconception. The study was carried out at KSPS, Somali Region, Ethiopia. The TTDT of cell biology and cell division was prepared and administered to 120 grade 10 and 11 students after their prior conceptions about the selected topi...
Abstract: We have chosen the urine innurioglobulin M (IgM) as system to study glycoprotein biosynthesis and carbohydrate processing. Secreted IgM heavy chain (m) has five glycoasylation sites which location and structures have been determined. chain variable region (VH) ia involved in antigen binding, while the constant region (CH) is responsible for the effect or functions in which the carbohydrate plays an important role.
Genetic diversity OF PLASMODIUM falciparum IN APPARENTLY HEALTHY SCHOOL children in ORE, Osun STATE.
ABSTRACT Faidherbia albida (Del.) A. Chev is a tree species native to Africa and the Middle East. It is an important agro-silvo pastural species owing to its morphological and physiological dynamics that mediate improvement of soil structure and fertility while offering several other benefits to farmers and the environment. Key among these is its reverse phenology, a phenomenon that allows the tree to compete minimally with crops while providing a favorable microclimate for their growth. It ...
ABSTRACT Despite the fact that virtually all households in Kenya grow maize over 60% of them are net maize buyers because they do not produce enough for their consumption. Kenya‘s current food supply situation and outlook give cause for serious concern. Maize is the main staple food averaging over 80% of total cereals (rice, wheat, millet and sorghum) in Kenya. Maize stocks are estimated to be depleted at all levels throughout the country. According to strategic grain bank report on food s...
ABSTRACT Blast disease (Pyricularia oryzae or Magnaporte oryzae) is a disease of the economic importance in rice, causing up to 100% yield loss. The aroma trait of rice grain encoded by the badh2 gene significantly increases its market value. Unfortunately, the aromatic IR97012-27-3-1-1-B (Supa234) line developed at IRRI is susceptible to Pyricularia grisea pathotypes. Improvement of IR97012-27-3-1-1-B (Supa234) rice has been carried out through introgression of R genes (Pi9 and Pita) at IRRI...
ABSTRACT Coffee is a small shrub which is a source of a stimulating beverage. It ranks as one of the world's major commodity crops and is the major export product of many countries including Kenya. Economic production of Arabica coffee in Kenya is greatly hindered by the Coffee Berry Disease (CBD) caused by Colletotrichum kahawae. Since the release of the resistant Ruiru 11 in 1985, efforts have been devoted to the improvement of the genetic base of resistance, but this has faced the problem ...
Abstract Cotton (Gossypium species) occupies a prime position as a fibre crop of the world. Today cotton is used as a natural fibre, while seeds are used for making cooking oil, soup and seed cake for animal feed industry. Wild cotton germplasm performance in Kenya has not been studied. While current cultivated variety (HART 89M) has a narrow genetic base, the wild cotton germplasm provides a gene pool that is required for its improvement. Understanding the correlation of traits influencing s...
ABSTRACT Vernonia Schreb. is a genus in the family Asteraceae. It has over 1000 species which may be trees, shrubs, woody climbers or herbs. Some of the species are economically important as sources of food and herbal medicine as well as for industrial purposes. Despite the economic importance of the species, the existing taxonomic and phylogenetic relationships among the taxa are not totally resolved. The objective of this study was to assess the genetic diversity of Vernonia species in Nig...
ABSTRACT Tuberculosis (TB) causes substantial human morbidity and mortality globally. About 10.4 million TB cases and 1.4 million deaths worldwide were reported in 2015. Kenya is among the 22 countries with highest TB burden. Microscopy is routinely used for Mycobacterium tuberculosis bacilli (Mtb) detection; however its sensitivity has been reported to be as low as 60% posing a problem for case detection. Rifampicin (RIF) is one of the major drugs for first line TB treatment; however, most p...
