During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R stands for...

Source: Laboratory of Dr. Andrew J. Steckl — University of Cincinnati A scanning electron microscope, or SEM, is a powerful microscope that uses electrons to form an image. It allows for imaging of conductive samples at magnifications that cannot be achieved using traditional microscopes. Modern light microscopes can achieve a magnification of ~1,000X, while typical SEM can reach magnifications of more than 30,000X. Because the SEM doesn’t use light to create images, the resulting pictures it...

We use an aberration-corrected scanning transmission electron microscope to define single-digit nanometer patterns in two widely-used electron-beam resists: poly (methyl methacrylate) and hydrogen silsesquioxane. Resist patterns can be replicated in target materials of choice with single-digit nanometer fidelity using liftoff, plasma etching, and resist infiltration by organometallics.
FAQs
Structured light and laser scanning record reflected light, while photogrammetry uses multiple images. The system processes these inputs to reconstruct surface geometry as a digital three-dimensional model. Their shared purpose is to preserve contours for precise measurement and documentation, while the capture approach determines whether the source data come primarily from projected or scanned light or from image sets.
Accurate surface geometry provides measurable contours rather than relying only on visual review or manual measurements. Clinicians and researchers can examine dimensions, compare anatomical surfaces, and retain a digital record for later analysis. This quantitative representation is especially useful when the goal is to identify change over time or evaluate whether treatment altered the documented surface.
Compared with manual measurements, the approach captures surface contours as digital data without physical contact. This can reduce reliance on manual measurement and create a record that supports repeated assessment. In medicine, that difference matters when clinicians need to document anatomy, compare changes over time, or evaluate treatment outcomes.
A basic workflow starts by selecting a capture approach such as structured light, laser scanning, or photogrammetry. The system then records reflected light or multiple images, reconstructs the resulting information into surface geometry, and produces a detailed three-dimensional model. Clinicians or researchers can subsequently use that model for measurement, documentation, comparison, or planning.
Medical teams can use these models to assess anatomy, monitor changes over time, and document the surface in a consistent digital format. The same data can support procedure planning and treatment-outcome evaluation, allowing the record to serve both immediate clinical decision-making and later quantitative review. This makes the method relevant when surface shape or contour is central to assessment.
A reconstructed model preserves the measured contours needed to inform custom device design and can provide a baseline for assessing later treatment results. Researchers and clinicians may compare models or measurements across time, using the digital record to track documented changes. The value lies in linking individualized surface information with planning, follow-up, and quantitative outcome assessment.
