Mineralogy, Particle-Size Distribution and Cement Dosage as Joint Controls of the Physico-Mechanical, Microstructural and Water-Transport Response of Some Cement-Stabilised Lateritic Soils from Western Cameroon in Road Construction

Lateritic soils are widely used in tropical road infrastructure, yet their response to cement treatment depends strongly on the properties of the untreated material. This study examines three lateritic soils collected at Ndandut, Kafeng and Bantoum III, in western Cameroon, under...

Addressing non-communicable diseases and injuries through an equity lens: insights from the Cameroon non-communicable disease and injury (NCDI) Poverty Commission

Background: Non-communicable diseases and injuries (NCDIs) constitute a leading cause of premature mortality globally, disproportionately affecting low- and middle-income countries (LMICs). To curb the rising burden of NCDIs in Cameroon, the Ministry of Public Health established...

Comparative virtual screening of African natural products against sickle haemoglobin: the β-chain hydrophobic acceptor pocket outperforms the Valβ6 surface for lateral-contact inhibition

Sickle cell disease arises from the Gluβ6→Valβ6 substitution in haemoglobin, which drives polymerisation through a lateral contact where Valβ6 inserts into a hydrophobic acceptor pocket on an adjacent β-chain. We compared two non-covalent inhibition strategies – capping Valβ6 and...

No Time to Dye: Portable Surface-Enhanced Raman Scattering for On-Site Detection of Sudan IV Dye in Palm Oil

Abstract The widespread use of Sudan IV dye as an adulterant in palm oil poses significant public health risks. This nonfood-grade dye, linked to carcinogenic effects, has prompted a pressing need for efficient, rapid, and reliable field-portable detection methods. This study inv...

Willingness to Participate in HIV Cure Research Among Young People Living with Perinatally Acquired HIV in the Centre Region of Cameroon: A Cross-Sectional Survey

Young people living with perinatally acquired HIV (YPLHIV) represent a unique population for HIV cure research, offering opportunities to assess interventions in a group for whom adherence to antiretroviral treatment (ART) is particularly challenging. Understanding their perspect...

Entomological and epidemiological trends during 5 years of combined indoor residual spraying and standard insecticide-treated nets in Kiremba, a malaria endemic site of Burundi

In Burundi, malaria due to Plasmodium falciparum is the leading cause of outpatient visit and hospital mortality. Anopheles gambiae s.l. and An. funestus s.l. are the primary malaria-transmitting vectors. The World Health Organization (WHO) recommends large-scale insecticide-trea...

Evidence, limitations and implications for renewable energy planning of daily global solar irradiation in tropical climate zones of Cameroon, predicted by machine learning

Accurate solar irradiance prediction is a crucial step for the efficient planning and deployment of solar energy systems, particularly in tropical regions like Cameroon where solar resources remain largely untapped. Despite growing global interest in solar energy prediction using...

Interface Engineering Toward High‐Efficiency CIAS Thin‐Film Solar Cells Using a Cadmium‐Free CuAlSe 2 Buffer Layer: A SCAPS‐1D Investigation

Cu(In,Al)Se 2 (CIAS)‐based thin‐film solar cells remain largely unexplored regarding buffer layer and interface engineering. This work reports a SCAPS‐1D investigation of CuAlSe 2 (CASe) as a cadmium‐free alternative to CdS, starting from a validated Glass/Mo/CIAS/CdS/ZnO/ITO/(Ni...

Proteinaceous bioactive compounds from Proteus mirabilis MN12 and DF14N suppress bacterial phytopathogens and prime plant defenses

Abstract Bacterial phytopathogens cause devastating yield losses in staple crops, yet sustainable alternatives to copper and streptomycin remain scarce. Proteus mirabilis , an environmental member of the Morganellaceae, is known for producing proticines, SOS-inducible, phage-tail...

Effect of Hypertension on the Health-related Quality of Life of People Living with Hypertension in Dschang, Cameroon: Comparative Analytical Cross-section

Hypertension has significant socioeconomic consequences and adversely affects the health-related quality of life (HRQOL) of people living with hypertension. In Cameroon, although one-third of adults have hypertension, no study has previously examined its impact on the HRQoL of in...

Towards a systemic approach to fitness-based feature optimization under limited resources for IoT attack detectors

Purpose The paper aims to propose, through feature extraction/selection techniques, a systematic approach for the optimization of features based on fitness and allowing IoT attack detectors to operate efficiently with limited resources. Design/methodology/approach Through a syste...

Neutrophil-to-lymphocyte ratio in periodontitis and after subgingival instrumentation in Cameroon: a controlled observational study with prospective follow-up

Periodontitis is associated with low-grade systemic inflammation, and the neutrophil-to-lymphocyte ratio (NLR) is a low-cost blood-cell-derived inflammatory index. Evidence from sub-Saharan African populations remains limited. This study compared baseline NLR between Cameroonian...

Metabolic health and cardiovascular risk among Cameroonian adults with and without obesity

Obesity contributes to increased morbidity and mortality, yet its metabolic heterogeneity remains underexplored in sub-Saharan Africa. This study examined associations between body composition, insulin sensitivity, inflammation, and the metabolically healthy profile (MHP), and as...

Frequent Itemset-based Graph Numbering using Execution Traces for Cache Misses Reduction in Graph Analysis Tasks

Graph analysis applications are increasingly used on large-scale datasets, where memory access patterns have a significant impact on performance. In such applications, poor data locality leads to a high number of cache misses, which in turn degrades execution time. To address thi...

High prevalence and endoscopic patterns of Helicobacter pylori Infection among symptomatic adults in Douala, Cameroon: sociodemographic and behavioral correlates

Abstract Background Helicobacter pylori infection remains a major cause of chronic gastritis, peptic ulcer disease, and gastric cancer, particularly in low- and middle-income countries. This study investigated the prevalence, diagnostic performance of commonly used tests, endosco...
