Biopolymeric and lipid-based nanotechnological strategies for the design and development of novel mosquito repellent systems: recent advances.

Mosquitoes are the most medically important arthropod vectors of several human diseases. These diseases are known to severely incapacitate and debilitate millions of people, resulting in countless loss of lives. Over the years, several measures have been put in place to control the transmission of mosquito-borne diseases, one of which is using repellents.

Improved antimalarial activity of caprol-based nanostructured lipid carriers encapsulating artemether-lumefantrine for oral administration.

Background: Artemether and lumefantrine display low aqueous solubility leading to poor release profile; hence the need for the use of lipid-based systems to improve their oral bioavailability so as to improve their therapeutic efficacy.

Aim And Objective: The objective of this work was to utilize potentials of nanostructured lipid carriers (NLCs) for improvement of the oral bioavailability of artemether and lumefantrine combination and to evaluate its efficacy in the treatment of malaria. This study reports a method of formulation, characterization and evaluation of the therapeutic efficacies of caprol-based NLC delivery systems with artemether and lumefantrine.

Political distrust and the spread of COVID-19 in Nigeria.

While studies have explored how health sector corruption, weak healthcare system, large-scale immune compromised population, misinformation and prevalence of highly congested slums contribute to the spread of COVID-19 in Nigeria, they have glossed over the impact of political distrust on the spread of the virus. This study explores the impact of political distrust on the spread of COVID-19 pandemic in Nigeria. The study utilised qualitative dominant mixed methods approach comprising telephone interviews and a survey of 120 educated Nigerians purposively selected from four COVID-19 most affected states including Lagos, Oyo, Kano and Rivers as well as the Federal Capital Territory, Abuja.

The impact of traffic sign deficit on road traffic accidents in Nigeria.

This study assesses the impact of traffic sign deficit on road traffic accidents in Nigeria. The participants were 720 commercial vehicle drivers. While simple random sampling was used to select 6 out of 137 federal highways, stratified random sampling was used to select six categories of commercial vehicle drivers.
