Predicting inflation component drivers in Nigeria: a stacked ensemble approach.

Unlabelled: Our study examined the disaggregation of inflation components in Nigeria using the stacked ensemble approach, a machine learning algorithm capable of compensating the weakness of an ensemble and a base learner with the strength of another. This approach gives flexibility of a synergistic performance of stacking each base learner and produces a formidable model that yields a high level of accuracy and predictive ability. We analyzed the test data, out-of-sample, and our analyses reveals a robust inflation prediction results.

Does political risk drive environmental degradation in BRICS countries? Evidence from method of moments quantile regression.

As a contribution to the political risk-environmental degradation literature, this study examines whether political risk drives environmental degradation in a multivariate framework. To achieve our study objective, we employed the method of moments quantile regression (MMQR) approach to analyze the effect of renewable energy use, economic growth, political risk, and globalization on quantiles of carbon emissions. The study utilized dataset stretching between 1990 and 2018 to investigate this interrelationship in the BRICS nations.

Trace elements; copper, zinc and selenium, in breast cancer afflicted female patients in LAUTECH Osogbo, Nigeria.

Background: There is an indication of the possibility of the direct or indirect influence of trace element in the development and prevention of malignant diseases, the contribution of the trace elements in the etiology of breast cancer has been under scrutiny.

Aims: The aim of this study was to determine the serum concentration of trace element in serum of female patients with breast cancer in comparison with healthy controls.

Chemopreventive and anti-leukemic effects of ethanol extracts of Moringa oleifera leaves on wistar rats bearing benzene induced leukemia.

Pharmacological exploitation of natural compounds has continued to lead to development of non-synthetic and non-toxic anticancer agents that are promising at ameliorating the menace of neoplastic diseases such as leukemia. This study is an attempt to determine the chemopreventive and antileukemic activities of ethanol extracts of Moringa oleifera leaves on benzene induced leukemia bearing rats. Leukemia was induced by intravenous injection of 0.
