According to career education and learning research, role models can significantly influence others’ decision-making processes and career choices. Such effects may be particularly relevant for potential entrepreneurs and future teachers, as much learning in these professions relies heavily on role models. Thus, educating students who desire to work in these fields might profit from a more role model-centered approach. However, research has shown that university educators rarely serve as role mod...

The trade or exchange of products has changed from the face-to-face format to a virtual one. Commerce then starts from a traditional environment to a virtual environment in the face of the growing impact of the internet, giving space to electronic commerce. Derived from the COVID-19 pandemic, face-to-face purchases were limited due to confinement, special days and hours, thereby causing an economic crisis throughout the globe. The MSMEs in search of virtual means to advertise th...

Cold atmospheric plasma (CAP) has received great attention due to its noteworthy ability, and has also been widely studied over few decades in physics, biology and medicine. The purpose of this study is to evaluate the cold atmospheric pressure plasma effects on the proliferation of breast cancer cells. MDAMB-231 was used for this experiment. MDA-MB-231 cells were cultured in 24-well plate and treated with non-thermal plasma. The viability of the cancer cells was determined by MTT assay. Differe...

Real-time monitoring of the gastrointestinal tract in a safe and comfortable manner is valuable for the diagnosis and therapy of many diseases. Within this realm, our review captures the trends in ingestible capsule systems with a focus on hardware and software technologies used for capsule endoscopy and remote patient monitoring. We introduce the structure and functions of the gastrointestinal tract, and the FDA guidelines for ingestible wireless telemetric medical devices. We survey the advanc...

We report a nematode electrotactic-response valve (NERV) to control the locomotion of Caenorhabditis elegans (C. elegans) in microfluidic devices. This nonmechanical, unidirectional valve is based on creating a confined region of lateral electric field that is switchable and reversible. We observed that C. elegans do not prefer to pass through this region if the field lines are incident to its forward movement. Upon reaching the boundary of the NERV, the incident worms partially penetrate the fi...

We describe a planar MEMS silicon structure to record ion channel currents in biological cells. The conventional method of performing an electrophysiological experiment, 'patch-clamping', employs a glass micropipette. The micropipette tip is a source of thermal noise because of its inherent, tapered, conical structure, giving rise to a large pipette resistance. This pipette resistance, when coupled with the biological cell capacitance, limits the available bandwidth of single ion channel recordi...

Computer simulations of realistic ion channel structures have always been challenging and a subject of rigorous study. Simulations based on continuum electrostatics have proven to be computationally cheap and reasonably accurate in predicting a channel's behavior. In this paper we discuss the use of a device simulator, SILVACO, to build a solid-state model for KcsA channel and study its steady-state response. SILVACO is a well-established program, typically used by electrical engineers to simula...

Infections from parasitic nematodes (or roundworms) contribute to a significant disease burden and productivity losses for humans and livestock. The limited number of anthelmintics (or antinematode drugs) available today to treat these infections are rapidly losing their efficacy as multidrug resistance in parasites becomes a global health challenge. We propose an engineering approach to discover an anthelmintic drug combination that is more potent at killing wild-type Caenorhabditis elegans wor...

In this paper, we present a movement-based assay to observe adaptability in Caenorhabditis elegans locomotion behavior. The assay comprises a series of sinusoidal microchannels with a fixed wavelength and modulating (increasing or decreasing) amplitude. The channel width is comparable to the body diameter of the organism. Worms are allowed to enter the channel from the input port and migrate toward the output port. Within channel sections that closely match the worm's natural undulations, the wo...

In this paper, we explore the use of microfluidic paper-based analytical devices (?PADs) to study the behavior of Caenorhabditis elegans. We show how these devices can be fabricated on paper and plastic substrates, as well as how to load, visualize, and transfer single and multiple nematodes. We also demonstrate the use of anthelmintic drug, levamisole, to perform chemical testing on C. elegans. Furthermore, we provide a custom program that is able to recognize individual worms on the ?PADs in r...
