Mohammed Abdullahi Talle, Aimé Bonny, Bukar Bakki, Faruk Buba, Charles Oladele Anjorin, Haruna Yusuph, Adama Kane
World Journal of Cardiovascular Diseases (WJCD) , 2015, DOI: 10.4236/wjcd.2015.55013
Abstract: Despite tremendous advances in the management of cardiovascular diseases and cardiac arrest, there is paucity of information regarding sudden cardiac death in sub-Saharan Africa. We present a two-year review of sudden cardiac death cases among patients managed at a Nigerian tertiary hospital. Patients admitted from January 2012 to December 2013 were prospectively followed-up and cases of sudden cardiac death identified. Diagnosis was based on records of events preceding death, direct interview of attending physician/nurses, and family members/eye witnesses for out-of-hospital sudden cardiac death. Causes of death were obtained from the death certificates for cases of in-hospital events. Three hundred and eighty eight (M:F = 1:1.3) patients with a mean age of 42.22 ± 19.30 years were admitted into the cardiac unit during the period, out of whom 56 (14.4%) died. Twenty three (41.1%) were classified as sudden cardiac death. The predominant etiology was ischemic cardiomyopathy (39.1%), followed by peripartum cardiomyopathy (21.7%) and dilated cardiomyopathy (17.4%). Rheumatic heart disease was diagnosed in 17.4%, while 4.3% had pulmonary hypertension. Nineteen (82.6%) of the subjects had congestive cardiac failure. Hypokalemia and hypocalcaemia were recorded in 2 (8.7%) patients who developed prolongation of the QT interval following commencement of diuretics. Chest-compression-only cardiopulmonary resuscitation was attempted in 12 (52.1%) with a success rate of 8.3%. Sudden cardiac death is common among our patients admitted with cardiovascular diseases. The most common etiology is ischemic cardiomyopathy, followed by peripartum cardiomyopathy. Most of the victims were young, and there were no optimum resuscitative measures.

Abstract:

Although the distribution of cytomegalovirus (CMV) infection has a wide regional variation, it is more common in Africa and Asia with high prevalence approaching 100% in some communities. CMV is a frequent opportunistic infection and major cause of morbidity and mortality among HIV patients with severe immunosuppression. It can be contracted from body fluid, including saliva, urine, blood, cervical secretions, and semen. CMV seropositivity is considered the best laboratory measure of past infection. We determined the prevalence of CMV and the risk factors associated with its acquisition in a population of HIV positive patients. Anti-CMV IgG seroprevalence was 100% among HIV infected subjects and 98.6% among controls. Having multiple sexual partners and traditional practices were identified as risk factors associated with risk of contracting CMV infection.

Abstract:
Introduction: Human Behavior is important as one of the determinants of transmission of Human Immunodeficiency Virus (HIV) infection. The risk of getting infected with HIV as well as subsequent developments and reactions after the infection has a direct bearing on human behavior. Positive behavior change of HIV infection prevention is less than the level of awareness and knowledge pertaining the disease among PLWHA. Method: A cross-sectional descriptive study was carried out on PLWHA attending clinic at the University of Maiduguri Teaching Hospital. A structured interviewer administered questionnaire was used to collect data by systematic random sampling technique. The objective of the research was to understand more about the behaviour of PLWHA and make recommendations on how to improve the behavioral change communications among PLWHA to curb the menace of HIV infection. Results: The people living with HIV/AIDs may be knowledgeable and having high awareness on HIV/AIDS but may not necessarily reflect into good behaviors concerning, taking the right steps to prevent menaces of HIV infection. The behavior of PLWHA was found to have gaps that portend danger in regard to making life more miserable to victims and portend more risk of getting others infected. The gaps are mainly related to psychological issues (e.g., lack of enjoyment or with condom use), beliefs, stigma and financial issues. Conclusion: Counselling should be used to inculcate technic, good morals, attitude and practices among PLWHA to prevent them from deliberate or spontaneous attempts to infect others with the virus. Safer and satisfying sex can be promoted through expanding knowledge and awareness about HIV/AIDS and removing stigma among the general populace through community health education as well as through schools’ curricula. Empowerment of the youths in public and private settings discourages exchanging sexual intercourse for financial gains.
Quality Primary Education in Tanzania: A Dream or Reality?
Kambuga Yusuph
International Journal of Independent Research Studies , 2013,
Abstract: The government of Tanzania has made a significant effort to improve the educational system to the extent that has been awarded and recognized for the attainment of the millennium development goals before the time frame of 2015. This incredible job on universal primary education enrollment has been due to the eradication of school fees for primary education in 2000 and primary school enrolment expanded to 95% in 2009. Pre-primary and secondary educations have also achieved steady expansions. Even though more classrooms have been built and the enrollment number reached 100%, many people claim that the quality of education in primary school is still poor and that pupils are not learning fundamental skills they need to find work prosper in their society and contribute to the national economic development. Tanzania is the only country in the world that needs to be recognized and is supposed to be in the Guinness book of having two thirds of primary school leavers who are unable to read and write well. They also lack basic numerical skills and 85% neither are unable to neither construct nor speak correct English sentences. Over 80% are selected to join secondary education or any other forms of further education. This paper discusses what went wrong. Is the name of primary education in Tanzania is an offence rather than a realization of human right? Dilapidated primary schools, inadequate facilities, poor trained and under- motivated teachers, poor working environment, inadequate supplies of teaching-learning materials, and lack of libraries which undermine rather than nourishing the potential of primary education. All these issues made me to articulate that quality primary education is a dream rather than a reality.
Isolation and Molecular Characterization of Elite Indigenous Rhizobia Nodulating Phaseolus bean (Phaseolus vulgaris L.)  [PDF]

Abstract: Nowadays application of biological nitrogen fixation (BNF) through rhizobia inoculums is highly promoted as a solution to solve the problem of poor soil fertility in areas where legumes are cultivated. This is due to the fact that, rhizobia enhance nitrogen fixation, induce disease resistance, reduce heavy metal in the soil, facilitate bioavailabity of iron in soil and is environmental friendly. To get rhizobia strains which are suitable for inoculants production, isolation and molecular characterization of elite rhizobia are highly needed. Molecular characterization acts as a spark plug for discovery of many microbes including Rhizobia. Multi Locus Sequence Analysis (MLSA), 16S rRNA gene sequence analysis, DNA-DNA hybridization and SDS-PAGE analysis of the whole-cell proteins are the molecular techniques mostly used in characterizing rhizobia. But before deciding to use or not to use rhizobia inoculants in certain areas, knowing the population size of indigenous rhizobia found in that area is very important, because this is a major factor which determines inoculums responses as well gives clues on which areas need or do not need inoculation. The Most Probable Number (MPN) method is mostly used in enumerating rhizobia population of the soil. Given that, in most of the developing countries, including Tanzania, Biological Nitrogen Fixation (BNF) technology is not fully flourished; more efforts in isolation, molecular characterization of elite rhizobia and estimation of indigenous rhizobia population in various areas are required.

Agricultural Journal , 2013, DOI: 10.3923/aj.2013.37.44
Abstract: This study aimed at evaluating and determining the impacts of Agricultural Marketing System Development Programme (AMSDP) on smallholder farmers and their participation as a way of empowerment in the market places. Among the programme objective which also become the central to this study includes empowerment of smallholder agricultural producers and their market linkages. Specifically, the study contributes on understanding the impacts of assets owned by household farmers on agricultural output market participation, level of market orientation of smallholder farmers in the study area and identifying transaction costs/factors that influence the decision of farmers to participate in agricultural product markets. The study employs interview, observation, statistical analysis using the logit model as mechanisms approach in estimating data from a randomly selected 163 households. The results show that insufficient land constitutes one of the most constraining assets facing rural households in Tanzania particularly in the area where this study was conducted. Households have access to very small pieces of land for cultivation where by 62% of farmers cultivates a farm size of <4 acres. Road conditions and household size were positively related to household participation in the market. Market orientation remains very low in the area studied, farming learned through extension officers and education of the household positively and significantly influenced the probability of household participation in the market. On the other hand, transaction costs/factors such as the distance to the market and the age of the household head were negatively and significantly associated with the probability of smallholder farmers participating in the market education influence stronger and significant at p = 0.01, farming learned through extension officers and age were significant at p = 0.05. The study highlights the recommendations that would reduce impediments of farmers participation in the markets.

Umaru MOHAMMED,Yusuph Amuda YAHAYA
Leonardo Journal of Sciences , 2010,
Abstract: The four steps Backward Differentiation Formulae (BDF) were reformulated for applications in the continuous form. The process produces some schemes which are combined in order to form an accurate and efficient block method for parallel or sequential solution of ordinary differential equations (ODE s). The suggested approach eliminates requirement for a starting value and its speed proved to be up when computations with the Block Discrete schemes were used.
Synthesis and characterisation of temperature responsive poly (2-ethyl-2-oxazolines
M Haruna
Bayero Journal of Pure and Applied Sciences , 2010,
Abstract: A bifunctional Poly(2-ethyl-2-oxazolines) containing hydrophobic end groups at both end of the polymer chains were synthesised by terminating a living cationic polymerisation with 4- bromomethyl benzoic acid. The results obtained for the clouding point measurement using UVvisible spectrophotometer shows that bifunctional polymer containing 20 monomer units (DP 20) exhibited a lower critical solution temperature (LCST) near 49oC due to formation of hydrophobic domains by the polymer end-groups. In contrast, the polymer with 50 monomer units does not exhibit any LCST between 20 to 70oC due to the imbalance in the hydrophilic-hydrophobic interaction in this polymer.
Seed contents of sika deer (Cervus nippon) dung and the fate of seeds in a temperate short grassland in an urban park in Japan

Journal of Ecology and Field Biology , 2011,
Abstract: Many studies have suggested the positive effects of grazing by large herbivorous mammals on seed dispersal, but little isknown about how herbivores could affect the fate of ingested seeds. This study examined the effects of seed ingestion bysika deer (Cervus nippon) on seed fate in a temperate grassland established in an urban park long resided by high densitiesof sika deer. I compared species composition and seasonal traits of seed abundance and maturity in the grasslandcommunity with those in deer fecal pellets. In total, 27 herbaceous species were observed, including the predominantZoysia japonica. Seed phenology and production differed among the three dominant species (Z. japonica, Digitariaviolascens, and Hydrocotyle maritima). Pellets contained at least 26 species of herbaceous seeds, and their abundancediffered among species. Of the 26 species, 15 were observed in the vegetation at the study site. The peak of seed abundancein pellets for the dominant species appeared 1 month after the peak of inflorescence production (but most ofthe inflorescences were immature and susceptible to digestion) and consequently corresponded to the peak of matureinflorescence. Because sika deer are likely to ingest seeds at any maturity stage in the grassland and immature seeds areless hardened, ingested immature seeds can suffer great losses. The results suggested that the survival of germable seedswith great losses of immature seeds may be a factor determining which plant species can be successfully dispersed byherbivores.

International Journal of Engineering and Technology , 2012,
Abstract: Pharma frauds are on the rise, counterfeit drugs are giving sleepless nights to patients, pharmaceutical companies and governments. The laws prohibiting the sales of counterfeit drugs cannot succeed without technological interventions. Several analytical techniques and tools including spectroscopy, holograms, barcoding, differentiated packing, radio frequency identification, fingerprints, hyperspectral imaging etc. have been employed over the years in combating this menace; however this challenge is becoming more sophisticated with the evolution of the World Wide Web and online pharmacies. This paper presents a review on the contribution of Information and Communication Technology (ICT) as a drug counterfeit countermeasure.
