Changes in thearubigin fractions and theaflavin levels due to variations in processing conditions and their influence on black tea liquor brightness and total colour
(Elsevier, 2004-03-30)Increase in coarser plucking standards significantly (P< 0.05) depressed levels of theaflavin (TF; μmol/g), total colour and brightness (spectrophotometer) of black tea. But total thearubigins (TR) TRSI, TRSII and ... -
Influence of region of production on clonal black tea chemical characteristics
(2008-05-01)Production of black tea from the same vegetatively propagated (VP) cultivars, in Kenya and Malawi, shows variations in both chemical composition and quality. Whereas it is possible to produce black teas with similar ... -
Correlation of theaflavins content and valuations of Kenyan black teas
(John Wiley & Sons, Ltd, 1986-05-01)Correlation between theaflavins content and tasters' valuations of Kenyan black teas generally give positive but statistically non-significant correlation coefficients. In 105 correlations using 12 samples each, only ... -
Changes in the chemical and sensory quality parameters of black tea due to variations of fermentation time and temperature
(Elsevier, 2001-12-31)The changes in theaflavins and residual catechin compositions, thearubigins TRSI and TRSII, sensory characteristics of total colour, brightness and briskness of black tea were investigated. It was demonstrated that the ... -
Flavanol composition and caffeine content of green leaf as quality potential indicators of Kenyan black teas
(1997)The Ñavanol composition and ca† eine content of green tea leaf, black tea quality parameters of theaÑavins, thearubigins, liquor brightness and total colour varied more among clones than with time of the year. In green ... -
The relationship between some chemical parameters and sensory evaluations for plain black tea (Camellia sinensis) produced in Kenya and comparison with simila...
(Elsevier, 2006-08-31)Reliable and accurately measurable chemical parameters that can be used to estimate black tea quality are desirable in trade, research and breeding programmes. Using plain Kenyan black tea from 11 cultivars, which gave ... -
Haplotypes of IL12B promoter polymorphisms condition susceptibility to severe malaria and functional changes in cytokine levels in Thai adults
(Immunogenetics, 2012)Polymorphic variability in immune response genes, such as IL12B, encoding the IL-12p40 subunit is associated with susceptibility to severe malaria in African populations. Since the role of genetic variation in conditioning ... -
Polymorphic Variability in the Interleukin (IL)-1Beta Promoter Conditions Susceptibility to Severe Malarial Anemia and Functional Changes in IL-1Beta Production
(PubMed, 2012)Interleukin (IL)-1beta is a cytokine released as part of the innate immune response to Plasmodium falciparum. Because the role played by IL-1beta polymorphic variability in conditioning the immunopathogenesis of severe ... -
Functional promoter haplotypes of interleukin-18 condition susceptibility to severe malarial anemia and childhood mortality.
(PubMed, 2012)Severe malarial anemia (SMA) is a leading cause of morbidity and mortality in children residing in regions where plasmodium falciparum transmission is holoendemic. Although largely unexplored in children with SMA, ... -
MIF (macrophage migration inhibitory factor) promoter polymorphisms and susceptibility to severe malarial anemia
(Journal of Infectious Diseases, 2012)Severe malarial anemia (SMA) resulting from Plasmodium falciparum infection is one of the leading causes of childhood mortality in sub-Saharan Africa. The innate immune mediator macrophage migration inhibitory factor ... -
Functional Haplotypes of Fc Gamma (Fcy) Receptor (FcyRIIA and FcyRIIB) Predict Risk to Repeated Episodes of Severe Malarial Anaemia and Mortality in Kenyan...
(SN Konah, 2012)Development of protective immunity against Plasmodium falciparum is partially mediated through binding of malaria-specific IgG to Fc gamma (γ) receptors. Variations in human FcγRIIA-H/R-131 and FcγRIIIB-NA1/NA2 affect ... -
Social and Demographic Characteristics of HIV-Positive Mother-Infant Pair and Their Association with Mother-To-Child Transmission of HIV in Vihiga, Kakamega, Bu...
(2012)The World Health Organization report indicates that in 2013~ 35 million people worldwide lived with HIV and AIDS. Of these, 3.2 million were children age< 15 years. The proportion of women living with HIV has remained ... -
Sputum Smear Conversion Time of HIV Infected and Uninfected Patients with Rifampicin and Isoniazid Mycobacterium tuberculosis gene Mutations in Western Kenya
(2012)Mono-resistant and multi-drug resistant tuberculosis (MDR-TB) has been enhanced by delays in the identification of resistant strains. However, resistance gene patterns and the extent of monoresistant TB and MDR-TB in ... -
The Trends of Progesterone Hormone in Advancing Pregnancy of Human Immunodeficiency Virus-infected Women: A Cohort Study in Western Kenya
(2012)Despite many studies on Human Immunodeficiency Virus (HIV) and pregnancy, there is still insufficient information regarding the effect of HIV on progesterone in advancing pregnancy. In a prospective cohort study, 44 ... -
Upregulation of Peripheral Blood Levels of Immune-Regulatory Interleukin-10 Cytokine in Human Immunodeficiency Virus-infected Compared to Non-infected Pregn...
(2012)Alterations in the cytokine status have been suggested to be at least partly responsible for the immune tolerance during pregnancy. Indeed, interleukin-10 (IL-10) cytokine is known to control inflammationinduced ... -
Biosecurity Factors Informing Consumer Preferences for Indigenous Chicken: A Literature Review
(2011)Indigenous chicken sector exhibits a very low adoption of biosecurity practices, thus is highly precarious in the wake of avian disease outbreak. Consumer preferences on the other hand seem strong for this chicken ... -
