Bennett, Michael J.; Rakheja, Dinesh – Developmental Disabilities Research Reviews, 2013
The neuronal ceroid-lipofuscinoses (NCL's, Batten disease) represent a group of severe neurodegenerative diseases, which mostly present in childhood. The phenotypes are similar and include visual loss, seizures, loss of motor and cognitive function, and early death. At autopsy, there is massive neuronal loss with characteristic storage in…

Tobler, Samuel; Köhler, Katja; Sinha, Tanmay; Hafen, Ernst; Kapur, Manu – CBE - Life Sciences Education, 2022
Undergraduate biology students' molecular-level understanding of stochastic (also referred to as random or noisy) processes found in biological systems is often limited to those examples discussed in class. Therefore, students frequently display little ability to accurately transfer their knowledge to other contexts. Furthermore, elaborate tools…

Valasek, Mark A.; Repa, Joyce J. – Advances in Physiology Education, 2005
In recent years, real-time polymerase chain reaction (PCR) has emerged as a robust and widely used methodology for biological investigation because it can detect and quantify very small amounts of specific nucleic acid sequences. As a research tool, a major application of this technology is the rapid and accurate assessment of changes in gene…

Morsink, M. C.; Dekter, H. E.; Dirks-Mulder, A.; van Leeuwen, W. B. – Biochemistry and Molecular Biology Education, 2012
In the current laboratory assignment, technical aspects of the polymerase chain reaction (PCR) are integrated in the context of six different bacterial outbreak scenarios. The "Enterobacterial Repetitive Intergenic Consensus Sequence" (ERIC) PCR was used to analyze different outbreak scenarios. First, groups of 2-4 students determined optimal…

A. Eliot Shearer – Volta Review, 2023
The past fifteen years has seen a dramatic improvement in our understanding of hearing and hearing loss. Scientists have worked to identify dozens of genes involved in hearing loss and elucidate the complex molecular machinery responsible for hearing. At the same time, there have been rapid advances in clinical diagnostic tools including imaging…

Saldarriaga-Gil, Wilmar; Cabal-Herrera, Ana Maria; Fandiño-Losada, Andrés; Vásquez, Andrés; Hagerman, Randi; Tassone, Flora – Journal of Applied Research in Intellectual Disabilities, 2021
Background: Fragile X syndrome (FXS) is the most common cause of inherited intellectual disability and autism spectrum disorder (ASD). In Colombia, there are no screening or testing protocols established for the diagnosis of FXS. In this study, we aimed to describe the diagnostic trends of FXS in Colombia. Methods: Data were included on 1322…

Yan, Jingmin; Chen, Jiangao; Mao, Xuhu; Li, Qian – Biochemistry and Molecular Biology Education, 2023
As a universal and extensively adopted technique, enzyme-linked immunosorbent assay (ELISA) can be used to detect and quantify small molecules in many applications both clinical and analytical. However, generally, students experiment mechanically using commercial ELISA kits according to the instructions and eventually produce a standard curve to…

Gandhi, Heta A.; Jakymiw, Sebastian; Barrett, Rainier; Mahaseth, Harshita; White, Andrew D. – Journal of Chemical Education, 2020
Three-dimensional visualization of molecular simulations in virtual reality (VR) is an emerging teaching tool in chemical education. This work describes a VR application which can generate a 3D molecular dynamics (MD) simulation from arbitrary molecular structures and renders that MD simulation trajectory on a VR headset in real-time. This system…

Trinh, Emily H.; Wolff, Anna M.; Naumiec, Gregory R. – Journal of Chemical Education, 2021
Nuclear magnetic resonance (NMR) spectroscopy is the tool of choice for organic chemists to determine the molecular structure of organic molecules and, as a result, is a fundamental topic in the organic chemistry curriculum. A novel laboratory module has been developed to expand the scope of NMR spectroscopy beyond structure validation at the…

Microcephaly presents heterogeneous genetic etiology linked to several neurodevelopmental disorders (NDD). Copy number variants (CNVs) are a causal mechanism of microcephaly whose investigation is a crucial step for unraveling its molecular basis. Our purpose was to investigate the burden of rare CNVs in microcephalic individuals and to review…
