Physicochemical characterisation and impact of Gryllus bimaculatus addition on gluten-free flour blends

Abstract Gryllus bimaculatus (field cricket) powder is a prospect in enriching gluten-free food products' protein and mineral contents. However, the technological impacts of replacing common gluten-free cereal flours with G. bimaculatus powder are still incipient. This study aimed to characterise nutritional composition, particle morphology, and particle size distribution of G. bimaculatus powder and the gluten-free flours (maize, rice, finger millet and proso millet). Additionally, it i...

A Duo 4-Plex Real Time PCR for Detection of Eight Tick-Borne Zoonoses in Kenya

Abstract/Overview Ticks harbor multiple pathogens, most of which can be transmitted to hu mans. The ensuing zoonoses display non-specific symptoms that make defin itive diagnosis difficult. We report here the development and evaluation of multiplex real time polymerase chain reaction (qPCR) assays for eight tick-borne zoonoses (TBZ). The assays were organized in duo formats of 4-plex each. Format 1 was optimized for Anaplasma phagocytophilum, Coxiella burnetii, Borrelia burgdoferi and Ehr...

Fungi and Aflatoxin Levels in Traditionally Processed Cassava(ManihotesculentaCrantz)Products in Homa-Bay County, Kenya

Abstract/Overview Cassava (Manihot esculenta Crantz) is a major source of carbohydrates, calcium, vitamins (B and C), and essential minerals and isthe third most important source of calories in the tropics. However, it is not clear if the traditional processing methods expose the products to microbial contamination. )is study assessed the levels of fungi and aflatoxin contamination in traditionally processed cassava products (Akuoga and Abeta). A total of 38 samples were collected from th...

Norm Inequalities for positive elementary operators and entanglement of states

Abstract/Overview We present norm inequalities for positive elementary operators via Cauchy-Schwarz inequality and Minkowskis inequality techniques. Norm inequalities are presented in Euclidean algebras linked to Minkowski’s light cones. Lastly, we explore the applications in quantum theory particularly in entanglement of states.

Projective Norms and Convergence of Norm-Attainable Operators

Abstract/Overview Let H be an infinite dimensional complex Hilbert space and B(H) the algebra of all bounded linear operators on H. We establish norm-attainability of operators via projective tensor norm. Moreover, we give results on the convergence of norm-attainable operators.

Modeling the Impact of Traveling Time on the Utilization of Maternity Services Using Routine Health Facility Data in Siaya County, Western Kenya

Abstract/Overview In Kenya, no studies have attempted to use routine health facility data disaggregated by level of care, to find out if there is a significant statistical relationship between physical accessibility and utilization of maternity services at the ward administrative level. A cross-sectional study design used publicly available geospatial data in combination with routine data from the web-based district health information software (DHIS2) platform. Access Mod (version 5.2.6) ...

Microbial infections in the twenty first century: a continuous challenge

Abstract/Overview Ever since the first case report of HIV infection approximately twenty years ago, enormous human and material resources have been put in place to assist in the control and management of the scourge. With an increase in number of cases of immunosuppression came an increase in the number of microbial organisms, which were previously unknown. Some, which have existed albeit at an equilibrium with the human immune system and by extension the body’s defence mechanism have f...

Evaluation of three rapid diagnostic test kits in the diagnosis of plasmodium species infections among primary school children in Baringo County, Kenya

Abstract/Overview Background: Due to the difficulty in implementing microscopy-based definitive diagnosis of malaria especially in resource-poor areas, rapid diagnostic test (RDT) kits as alternatives have been developed by different companies. Kits from different companies may differ in sensitivity and specificity. It is therefore imperative to conduct field evaluation of kits from different manufacturers before they are recommended for widespread use in diagnosis of malaria. The present...

Modeling of liver cancer risk factors and dynamics at community level

Abstract/Overview Hepatocellular carcinoma (HCC) is a malignant cancer of the liver arising from uncontrolled multiplication of the abnormal liver cells. It is an ignored public health condition where patients come late to the hospital at terminal stages. Its development is proceeded by liver inflammation arising from the risk factors of HCC affecting the liver. HCC is one of the few cancers with both infectious and non-infectious causes. The common causes range from infections with viral...

Evolution of the primate trypanolytic factor APOL1

Abstract/Overview ApolipoproteinL1 (APOL1) protects humans and some primates against several African trypanosomes. APOL1 genetic variants strongly associated with kidney disease in African Americans have additional trypanolytic activity against Trypanosoma brucei rhodesiense, the cause of acute African sleeping sickness. We combined genetic, physiological, and biochemical studies to explore coevolution between the APOL1 gene and trypanosomes. We analyzed the APOL1 sequence in modern and a...

Schistosoma haematobium and soil-transmitted Helminths in Tana Delta District of Kenya: infection and morbidity patterns in primary schoolchildren from two isolated villages

Abstract/Overview Schistosomes and soil-transmitted helminths (STH) (hookworm, Trichuris trichiura and Ascaris lumbricoides) are widely distributed in developing countries where they infect over 230 million and 1.5 billion people, respectively. The parasites are frequently co-endemic and many individuals are co-infected with two or more of the species, but information on how the parasites interact in co-infected individuals is scarce. The present study assessed Schistosoma haematobium and...

Technical efficiency in public hospitals in Kenya: a two –stage data envelopment analysis

Abstract/Overview The paper uses the DEA technique to estimate efficiency scores in Kenyan public hospitals and then applies the Tobit regression to study inter-hospital variation in the scores. The DEA analysis reveals that small hospitals are more efficient than large hospitals, with efficiency levels ranging from 74-91% in small DMUs and from 57-78% in large DMUs. Tobit regression analysis shows efficiency scores are negatively correlated with the hospital’s distance from the manager...

Mathematical modelling of liver cancer in Western Kenya

Abstract/Overview Liver cancer, also known as hepatocellular carcinoma (HCC) is a primary cancer of the liver and the fifth cause of mortality world-wide. It is a global public health problem which is poorly addressed in the developing countries. Data on prevalence and incidence is scanty leading to inability to predict the burden of HCC in the developing world and this leads to poor policy framework for management and control of HCC. More-over, management and control of HCC is poorly add...

Spatial distribution and settlement system of the stone structures of south-western Kenya

Abstract/Overview During the Later Iron Age period in Kenya, communities that built structures known in the local language as ohingni (singular - ohinga)' occupied the Lake Victoria region in south-western Kenya. The term refers to both stone-built and earth-built settlement enclosures widely distributed in the Nyanza region, that were abandoned before and during the colonial period. Their distribution and contents, in terms of archaeological remains and use of space, indicate that they w...

Statistical Analysis of the Effect of Educational Opportunities and Community Involvement on Adolescents and Sexual Reproductive Health Policy on Retention of Girl Child in Public Secondary S

Abstract Girls’ retention in schools has been found to be a major challenge. Failure to retain girlsin secondary schools can be considered as a waste of potential human resources andmoney spend on them in primary education and time lost in sending them to schoolin the first place. These girls may become a breed of illiterate women who are lessproductive economically, socially and politically. Among the critical contemporary socialissues affecting many countries is teenage pregnancies. This...
