Hypertension in African populations: Review and computational insights
(MPDI, 2021)Hypertension (HTN) is a persistent public health problem affecting approximately 1.3 billion individuals globally. Treatment-resistant hypertension (TRH) is defined as high blood pressure (BP) in a hypertensive patient ... -
Common bean as a potential crop for future food security: an overview of past, current and future contributions in genomics, transcriptomics, transgenics and proteomics
(Taylor & Francis Open Access, 2021)Common bean is an important legume crop having high quality protein, micronutrients, vitamins and antioxidants, which makes it a “grain of hope” for poor communities. Hence, a good number of breeding activities have been ... -
Stress modulation as a means to improve yeasts for lignocellulose bioconversion
(Springer, 2021)The second-generation (2G) fermentation environment for lignocellulose conversion presents unique challenges to the fermentative organism that do not necessarily exist in other industrial fermentations. While extreme ... -
Cheminformatic profiling and hit prioritization of natural products with activities against Methicillin-Resistant Staphylococcus Aureus (MRSA)
(MPDI, 2021)Several natural products (NPs) have displayed varying in vitro activities against methicillinresistant Staphylococcus aureus (MRSA). However, few of these compounds have not been developed into potential antimicrobial ... -
Indigenous African cereal crops can contribute to mitigation of the impact of climate change on food security
(Arid land institute, 2021)Zea mays L. (maize) is one of the top three cultivated cereals globally, along with wheat and rice. The United States, China, and Brazil are among the largest producers of maize, producing approximately 79% of the world’s ... -
Antioxidant responses are associated with differences in drought tolerance between maize and sorghum
(Arid land institute, 2021)Drought is a major cause of decreased yield in crops worldwide. Sorghum (Sorghum bicolor) and maize (Zea mays) are two of the key crops in Africa serving as human food as well as livestock feed. For improved crop ... -
Evaluation of the morpho-physiological, biochemical and molecular responses of contrasting medicago truncatula lines under water deficit stress
(MPDI, 2021)Medicago truncatula is a forage crop of choice for farmers, and it is a model species for molecular research. The growth and development and subsequent yields are limited by water availability mainly in arid and semi-arid ... -
Role and merits of green based nanocarriers in cancer treatment
(MPDI, 2021)The use of nanocarriers for biomedical applications has been gaining interests from researchers worldwide for the delivery of therapeutics in a controlled manner. These “smart” vehicles enhance the dissolution and the ... -
Venom proteomic analysis of medically important Nigerian viper Echis ocellatus and Bitis arietans snake species
(Elsevier, 2021)Snakebite envenoming remains a neglected tropical disease which poses severe health hazard, especially for the rural inhabitants in Africa. In Nigeria, vipers are responsible for the highest number of deaths. Hydrophili ... -
Overweight/obesity and chronic health conditions in older people with intellectual disability in Ireland
(Wiley, 2021)This study examines overweight/obesity and chronic health conditions (CHCs) in older people with intellectual disability (ID).Data for this cross-sectional observational study emanated from Wave 2 of the Intellectual Disability ... -
The low-redshift circumgalactic medium in SIMBA
(Oxford University Press, 2021-08)We examine the properties of the low-redshift circumgalactic medium (CGM) around star-forming and quenched galaxies in the SIMBA cosmological hydrodynamic simulations, focusing on comparing H I and metal line absorption ... -
Functional metal oxides synthesized using natural extracts from waste maize materials
(Elsevier, 2021)We show in this article the possibilities of employing an environmentally friendly, uncomplicated, economical and sustainable green synthesis technique effected by natural extracts from waste maize (zea mays lea) materials to ... -
Covid-19 and cancer therapy: Interrelationships and management of cancer cases in the era of Covid-19
(Hindawi, 2021)'e COVID-19 global epidemic poses this generation’s biggest worldwide public health challenge probably since the 1918 influenza epidemic. Recent reports on two new variants have triggered a dramatic upsurge in research ... -
Recent advances in the detection of interferon‑gamma as a TB biomarker
(Springer, 2021)Tuberculosis (TB) is one of the main infectious diseases worldwide and accounts for many deaths. It is caused by Mycobacterium tuberculosis usually afecting the lungs of patients. Early diagnosis and treatment are essential ... -
Acylation of anisole with benzoyl chloride over rapidly synthesized fly ash–based hbea zeolite
(Frontiers Media, 2021)Stable HBEA zeolite with high surface area and strong acid sites was synthesized from coal fly ash–based silica extract via indirect hydrothermal synthesis. The rapid HBEA hydrothermal crystallization times of 8, 10, and ... -
Advances in nanotechnology towards development of silver nanoparticle-based wound-healing agents
(MPDI, 2021)Since antiquity, silver-based therapies have been used in wound healing, wound care and management of infections to provide adequate healing. These therapies are associated with certain limitations, such as toxicity, ... -
Scaling factors for channel width variations in treelike flow field patterns for polymer electrolyte membrane fuel cells - An experimental study
(Elsevier, 2021)To have a uniform distribution of reactants is an advantage to a fuel cell. We report results for such a distributor with tree-like flow field plates (FFP). Numerical simulations have shown that the width scaling parameters ... -
