BACKGROUND: The osteoconductive properties of collagen containing xenogeneic bone blocks (CCXBB) remain unclear. The aim of this prospective single-arm clinical study was to assess the histological outcomes of CCXBB blocks used as bone replacement grafts for lateral bone augmentation procedures. METHODS: In 15 patients with severe horizontal alveolar ridge resorption, lateral augmentation procedures were performed using CCXBB as bone replacement grafts. Twenty-six weeks postoperatively, a re-entry procedure was performed to evaluate the bone width for adequate implant placement and two histological specimens were retrieved from each patient, one being processed for ground sectioning and the other for decalcified paraffin-included sections...

An improvement in quality of medical external post-mortem examinations among others can be achieved by more intensive training of medical students. Modern learning and teaching methods such as e-learning modules and SkillsLab stations should be used for this. The introduction of corresponding methods of assessment such as the OSCE procedure is necessary to test the success of learning. In Halle (Germany), two OSCE stations on the subject of external post-mortem examinations were introduced in 2016. The 'practical external post-mortem examination' station test skills and abilities students have learned during practical external post-mortem examination in small group classes on a simulation doll...

BACKGROUND AND OBJECTIVES: The diagnosis of dementia is a challenge for physicians due to numerous interrelated barriers. Research shows that this difficulty may be rooted in an incomplete knowledge about dementia. To address this gap, we developed an assessment scale of resident confidence in the diagnosis of dementia and used it to compare resident confidence to their practical ability to diagnose dementia. METHODS: The study used a piloted confidence assessment tool for diagnosing dementia correlated with family medicine residents (n=45) performance during an objective structured clinical examination (OSCE)...

THEORY: Models on pre-assessment learning effects confirmed that task demands stand out among the factors assessors can modify in an assessment to influence learning. However, little is known about which tasks in objective structured clinical examinations (OSCEs) improve students' cognitive and metacognitive processes. Research is needed to support OSCE designs that benefit students' metacognitive strategies when they are studying, reinforcing a hypothesis-driven approach. With that intent, hypothesis-driven physical examination (HDPE) assessments ask students to elicit and interpret findings of the physical exam to reach a diagnosis ("Examine this patient with a painful shoulder to reach a diagnosis")...

We designed and fabricated a random-size inverted-pyramid-structured polydimethylsiloxane (RSIPS-PDMS) sticker to enhance the light absorption of solar cells and thus increase their efficiency. The fabricated sticker was laminated onto bare glass and crystalline silicon (c-Si) surfaces; consequently, low solar-weighted reflectance values were obtained for these surfaces (6.88 and 17.2%, respectively). In addition, we found that incident light was refracted at the PDMS-air interface of each RSIPS, which redirected the incident power and significantly increased the optical path length in the RSIPS-PDMS sticker which was 14...

We developed a facile method for treating polyimide-based organic gate insulator (OGI) surfaces with self-assembled monolayers (SAMs) by introducing metal-oxide interlayers, called the metal-oxide assisted SAM treatment (MAST). To create sites for surface modification with SAM materials on polyimide-based OGI (KPI) surfaces, the metal-oxide interlayer, here amorphous alumina (α-Al2O3), was deposited on the KPI gate insulator using spin-coating via a rapid sol-gel reaction, providing an excellent template for the formation of a high-quality SAM with phosphonic acid anchor groups...

Over the past decades, fullerene derivatives have become the most successful electron acceptors in the organic solar cells (OSCs) and have achieved great progress, showing power conversion efficiencies (PCEs) of over 11%. However, fullerenes have some drawbacks such as weak absorption, limited energy-level tunability, and morphological instability. In addition, fullerene-based OSCs usually suffer from large energy losses of over 0.7 eV, which limits further improvement of the PCE. Recently, non-fullerene small molecules have emerged as promising electron acceptors in OSCs...
