Toxicity of Oils Extracted From the Arils of (K.D. Koenig) in Wistar Rats.

oil, a substance with a rich history of use for its nutritional, therapeutic, traditional, and cosmetic benefits, was the focus of our study. We investigated the impact of consuming edible oil from . arils on Wistar rats.

Novel elastomeric spiropyran-doped poly(dimethylsiloxane) optical waveguide for UV sensing.

Novel poly(dimethylsiloxane) (PDMS) doped with two different spiropyran derivatives (SP) were investigated as potential candidates for the preparation of elastomeric waveguides with UV-dependent optical properties. First, free-standing films were prepared and evaluated with respect to their photochromic response to UV irradiation. Kinetics, reversibility as well as photofatigue and refractive index of the SP-doped PDMS samples were assessed.

African primary research publications in plastic surgery: A PRISMA-S-compliant systematic review.

Background: Plastic surgery (PS) in Africa is a relatively young surgery specialty, and the number of available plastic surgeons on average is one or two surgeons per country in many African low-income countries. This systematic review aims to geographically map the research activities through scientific publications of African PS centres, between February 2012-February 2023.

Methods: We searched four literature databases (Medline, Embase, Google Scholar and African Journal Online) and did a manual search.

Optoelectronic Pressure Sensor Based on the Bending Loss of Plastic Optical Fibers Embedded in Stretchable Polydimethylsiloxane.

We report the design and testing of a sensor pad based on optical and flexible materials for the development of pressure monitoring devices. This project aims to create a flexible and low-cost pressure sensor based on a two-dimensional grid of plastic optical fibers embedded in a pad of flexible and stretchable polydimethylsiloxane (PDMS). The opposite ends of each fiber are connected to an LED and a photodiode, respectively, to excite and measure light intensity changes due to the local bending of the pressure points on the PDMS pad.

Lower extremity amputations (LEAs) in a tertiary hospital in Togo: a retrospective analysis of clinical, biological, radiological, and therapeutic aspects.

Background: We analysed the clinical, biological, radiological profiles, and therapeutic patterns of the patients who underwent a surgical lower extremity amputation (LEA) in Togo from 2010 to 2020.

Methods: Retrospective analysis of clinical files of adult patients who underwent an LEA at a single centre (Sylvanus Olympio Teaching Hospital) from 1st January 2010 to 31st December 2020. Data were analysed by CDC Epi Info Version 7 and Microsoft Office Excel 2013 software.
