The COVID-19 pandemic and subsequent policies (e.g., social distancing, travel restrictions) challenged both organizers for and attendees of programs typically held in person. Many scientific training programs quickly adapted to virtual formats by incorporating digital assets developed for virtual learning and remote social engagement. At the…

The carbonyl group of an aldehyde or ketone reacts with different types of nucleophiles through a nucleophilic addition reaction. When the nucleophile is water, the product obtained is a "gem"-diol or geminal diol. This functionalization is unstable and quickly reverts to the parent carbonyl group. The chemistry of "gem"-diols…

A successful completion of first-year science courses is critical for an on-time entry into the undergraduate health care programs of nursing, radiology, respiratory care, and sonography at a small, private health care institution. The inability of undergraduate students to pass science courses leads to drop-out or a delay of entry into their…

The background of the study is that the planar film heterostructures are nowadays the most common objects nanophotonic and nanoelectronic technologies. The authors noted that, among such objects found so-called quantum wells, which are formed by a complex series of nanoscale layers are deposited with differing elemental composition, and simple…

In recent years, there has been a growing interest in white matter anatomy of the human brain. With advances in brain imaging techniques, the significance of white matter integrity for brain function has been demonstrated in various neurological and psychiatric disorders. As the demand for interpretation of clinical and imaging data on white…

In 2008 a new clinical anatomy curriculum with integrated medical imaging component was introduced into the University of Sydney Medical Program. Medical imaging used for teaching the new curriculum included normal radiography, MRI, CT scans, and ultrasound imaging. These techniques were incorporated into teaching over the first two years of the…

William Henry Bragg moved from Cambridge in Britain to South Australia to take up a professorship at the University of Adelaide in 1885. He brought with him a broad interest in many areas of physics, but when Wilhelm Roentgen discovered X-rays in the 1890s, Bragg's interest was stimulated. William's Australian-born son, Lawrence (WL Bragg), began…

Modern drug discovery programs require the contribution of researchers in a number of specialist areas. One of these areas is structural biology. Using X-ray crystallography, the molecular basis of how a drug binds to its biological target and exerts its mode of action can be defined. For example, a drug that binds into the active site of an…

Radiologic science is an essential part of the healthcare continuum and preparing radiologic science students with experiential learning is essential. It is from this experience working with the patient that students begin to prepare for entry-level practice. The purpose of the study was to examine the attitudes of current radiologic science…

Previous authors have shown that the transverse relaxivity R[subscript 2][superscript *] and frequency shifts that characterize gradient echo signal decay in magnetic resonance imaging are closely associated with the distribution of iron and myelin in the brain's white matter. In multiple sclerosis, iron accumulation in brain tissue may reflect a…

The purpose of this study was to explore the behavioral intention of directors of educational programs in the radiologic sciences to adopt handheld devices to aid in managing student clinical data. Handheld devices were described to participants as a technology representing a class of mobile electronic devices including, but not limited to,…

This article describes a project of unwrapping an ancient Egyptian mummy using x-ray computed tomography (CT). About 600 x-ray CT images were obtained through the mummified body of a female named Tjetmutjengebtiu (or Jeni for short), who was a singer in the great temple of Karnak in Egypt during the 22nd dynasty (c 945-715 BC). The x-ray CT images…

Describes the use of nuclear medicine techniques in diagnosis and therapy. Describes instrumentation in diagnostic nuclear medicine and predicts future trends in nuclear medicine imaging technology. (Author/MM)

Describes an experience with the use of a radioactive tracer in medicine. Discusses the methodology of how the tracer was used. (CCM)

A study identifies a compound from a set of monoterpenes using infrared (IR) and one-dimensional (1D) nuclear magnetic resonance (NMR) techniques. After identifying the unknown, each carbon and proton signal can be interpreted and assigned to the structure using the information in the two-dimensional (2D) NMR spectra, correlation spectroscopy…
