This study compared bone mineral density (BMD) of the spine obtained by dual-energy X-ray absorptiometry (DEXA), nutritional status, biochemical markers, and gastrointestinal (GI) symptoms in 4-8 year old boys with Autism Spectrum Disorder (ASD) with a group of age-matched, healthy boys without ASD. Boys with ASD had significantly lower spine BMD…

An integrated and research-focused laboratory experiment is developed to introduce the "antenna effect" occurring in luminescent lanthanide complexes to students. Students synthesized a lanthanide metal-organic framework (Ln-MOF) with the formula of [Eu(BTPCA)(H O)]·2DMF·nH[Subscript 2]O (Eu-BTPCA, H[subscript 3]BTPCA =…

Biocompatible and biodegradable block copolymers composed of poly(ethylene glycol) (PEG) and aliphatic polyester are a class of promising biomaterials. Herein, a teaching experiment was designed to furnish undergraduates with a reliable method to synthesize an amphiphilic poly([epsilon]-caprolactone)-PEG-poly([epsilon]-caprolactone) (PCL-PEG-PCL)…

In a study conducted in 2011, the use of full body digital X-ray images (Lodox® Statscan®) and drawings were described for surface anatomy education during which suggestions were made by students on how to improve the method. Educational innovations should continuously be adjusted and improved to provide the best possible scenario for student…

Simply stated, light is nature's way of transferring energy through space. Discussions of light usually refer to visible light, which is perceived by the human eye and is responsible for the sense of sight. We see however, only a small part of the light spectrum. Light connects us as we sit and tell yarns around camp fires. Yet, one in every four…

Every substance is associated to emission of electromagnetic radiation whose peaks are essentially influenced by temperature. Hot bodies (i.e., at T >700 °C) emit electromagnetic radiation in the field of visible light (incandescent light). The radiation emitted by cold bodies (i.e., at normal ambient conditions) in the visible light range is…

Implementing the case study method in a practical X-ray crystallography course designed for graduate or upper-level undergraduate chemistry students is described. Compared with a traditional lecture format, assigning small groups of students to examine literature case studies encourages more active engagement with the course material and…

To examine bone mass in children and adolescents with autism spectrum disorders (ASD). Risperidone-treated 5 to 17 year-old males underwent anthropometric and bone measurements, using dual-energy X-ray absorptiometry and peripheral quantitative computed tomography. Multivariable linear regression analysis models examined whether skeletal outcomes…

The coronavirus (COVID-2019) has spread very rapidly over many countries around the world, producing an outbreak of acute infectious pneumonia. Medical imaging devices play a vital role in early diagnosis, evaluating severity and disease prognosis of confirmed patients with COVID-19. The aim of the study is to evaluate the awareness level of…

The chemistry of metal-organic frameworks (MOFs), a new class of emerging crystalline porous solids with three-dimensional (3D) networks composed of metals and multidentate organic molecules, was introduced by using three differently shaped crystals. We reported new and mild MOF synthesis methods that are simple and devised to be performed in high…

In medical education and preclinical, clinical and transdisciplinary studies, tutors should be able to perform and offer qualitative study courses with more articulated perspective on higher educational sustainable development in higher education. Digital images have found their direct way to education in different medical areas. The aims of the…

The various radiation types that make up the electromagnetic (EM) spectrum are ubiquitous and highly significant in modern society. Detection of visible light by the eye facilitates sight, radio waves and microwaves are used in communication technologies, x-rays are used in medical imaging, and gamma rays are frequently employed in medical…

The process of entering prison as a civilian is such … sign in … send stuff through x-ray … walk through metal detector … get patted down by officer … show badge, get buzzed through steel door … get buzzed through another steel door … get buzzed through another steel door … show badge to officer, get buzzed through steel door. Enter the yard and…

While X-ray powder diffraction (XRPD) is a fundamental analytical technique used by solid-state laboratories across a breadth of disciplines, it is still underrepresented in most undergraduate curricula. In this work, we incorporate XRPD analysis into an inquiry-based project that requires students to identify the crystalline component(s) of…

The traditional assignment of oxidation states to organic molecules is problematic. Accordingly, in 1999, Calzaferri proposed a simple and elegant solution that is based on the similar electronegativities of carbon and hydrogen: hydrogen would be assigned an oxidation state of zero when bonded to carbon. Here, we show that X-ray photoelectron…
