The study used a quasi-experimental study design to evaluate the effect of a role-play teaching strategy on science students’ interest in the teaching and learning of photosynthesis. The sample comprised third-year biology students of 3 intact classes totaling 157 at Ghana Senior High School, Koforidua. Sixty-three (63) of the students, 21 for each class, volunteered to participate in the role-play. The students answered a 5-point Likert scale questionnaire on whether the use of role-play for te...

Background: Fractures of the long bones are becoming increasingly common in our environment, due to the upsurge in road accidents. In low- and middle-income countries such as Cameroon, where universal health coverage is still in its infancy, patients tend to orient their treatment choices according to their financial means. This study aimed to assess the functional outcome of patients with long bone fractures discharged against medical advice at the Yaounde Emergency Center. Methods: We conducte...

Although there are ongoing controversies, tooth extraction as a solution for various malocclusions has been a well-established practice for decades. While premolar extractions are the most common, there are cases where atypical extractions are indicated. While decision-making can be challenging, when cases are carefully selected, the treatment outcomes are comparable to, and sometimes better than, those achieved with conventional extraction patterns. This article presents three clinical cases su...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor. DC motors are widely utilized in various applications due to their simplicity and efficiency; however, robotics and automation are only performed effectively through proper control of the operational parameters. This research aims to develop a strong motor control system that can dynamically chang...

Human Herpesviruses (HHVs) are a group of large DNA viruses that can establish lifelong infections in their hosts. They achieve this by switching between two phases: the lytic phase, where the virus actively replicates, and the latent phase, where the virus remains dormant but can reactivate later. A key factor in this process is microRNAs (miRNAs)—small, non-coding RNA molecules that regulate gene expression. In human cells, miRNAs play a crucial role in controlling various biological processes...
