The synthesis of a [2]rotaxane through three- or five-component coupling reactions has been adapted to an organic chemistry experiment for upper-division students. The experimental procedure addresses the search for the most favorable reaction conditions for the synthesis of the interlocked compound, which is obtained in a yield of up to 71%.…

A simple photometric device was built to measure the kinetics of the title reaction. The device consisted of a green light-emitting diode (centered at 520 nm), a sample vial, a photodiode, and an Arduino microcontroller board. These parts were mounted on a black poly(lactic acid) holder which was manufactured by utilizing three-dimensional…

Metabolic Control Analysis (MCA) is a systems biology approach that measures the control of a metabolic step on the overall flux of a metabolic pathway. In undergraduate courses in biochemistry, learning of MCA can be encouraged by experimental activities demonstrating practical applications of the MCA theory. In this work, we present a laboratory…

Based on four types of laboratory safety questions (chemical, biological, physical, and medical), a cross-sectional survey of students at Kunming University of Science and Technology (China) was carried out to determine the awareness of laboratory safety among university students. The survey was completed by 335 students in total, with a response…

Due to its haptic and interactive nature, virtual anatomy provides an opportunity for small-group learning, enabling students to develop their group work skills before they graduate. However, there is currently little practical guidance supported by pedagogic principles detailing how to incorporate it into curricula. Anatomy educators at the…

This study explored the effects of a novel intervention, binaural beats (BB), on anxiety levels of anatomy students during cadaveric dissections and its impact on the learning environment. The study was quasi-experimental, employing a purposive sampling strategy. State (SA) and trait (TA) anxiety levels were measured using the State-Trait Anxiety…

This project report describes the process of a team of undergraduate researchers (Chemistry and Nursing majors), who analyzed 20th-century medical kits housed at The Columbus Museum (Columbus, GA, USA). Curators and museum personnel were unfamiliar with the contents and needed assistance in identifying the various chemical contents. Items were…

By hosting a college students' laboratory skills contest, we provide an interesting activity for students to cultivate good laboratory practices and thereby improve their laboratory skills. The substance of this contest is the detection of the hardness of water, which involves numerous laboratory skills such as solution preparation, weight by…

This study investigated how human dissection affects students' spiritual beliefs, and how their existing spiritual beliefs influence their perceptions of human dissection. This cross-sectional study assessed 760 medical students with human dissection experience using an online questionnaire developed from interviews and the Spirituality…

The realities of accidents free situation in academic workshops and classrooms are anchored on strict adherence to laboratory safety rules and regulations, and normal classroom behaviour. The reality is less abided by Electrical/Electronic Technology students in classroom and workshops in the universities, causing accidents that lead to minor and…

This descriptive report explores the implementation of the use of plastinated specimens in a Doctor of Physical Therapy human anatomy curriculum as an alternative to traditional body donor dissection. Plastination, a preservation technique developed in the 1970s, creates durable and flexible specimens that retain detailed anatomical features. The…

Semimicro pressure filtration is carried out by pressurizing a suspension through pushing the piston of a gas-filled plastic syringe whose needle perforates the closure of a cylindrical filter funnel. Basic features as well as pros and cons of vacuum and pressure filtration are pointed out and compared to support rational choice between the two…

To this day, autopsies and dissections have been essential in medical education, but declining autopsy numbers have endangered this long-standing tradition. Students' perceptions of these teaching methods should be constantly updated to help educators understand how to achieve their teaching goals. The purpose of this study was to explore the…

Although the methods for medical education continue to evolve due to the development of medicines, the cadaver dissection course still plays a fundamental role. The cadaver dissection course allows students to learn to handle instruments correctly while actively exploring three-dimensional anatomy. However, dissection comes with the risk of…

While cadaver dissection and prosection are deemed quintessential methods for studying anatomy, these methods are attenuated by the flat, 2-D structures incorporated into didactic segments of the anatomy courses that minimize students' ability to comprehend anatomy, leading to constraints in the teaching and learning experience. Several tools,…
