How to distribute a set of points uniformly on a spherical surface is a longstanding problem that still lacks a definite answer. In this work, we introduce a physical measure of uniformity based on the distribution of distances between points, as an alternative to commonly adopted measures based on interaction potentials. We then use this new measure of uniformity to characterize several algorithms available in the literature.

Course-Based Research Experiences (CRE) and the inclusive Research and Education Communities (iREC) are two successful and impactful reform efforts that integrate research and teaching. The aim of this study is to explicate the professional identity of instructors who implement a CRE within an established iREC and to explore how this identity contributes to the success of these programs.

We present the genome sequence of three lytic bacteriophages. Upon analysis of sequence similarity, we identified the viruses as a part of an unclassified species within the genus in the class.
View Article and Find Full Text PDFImmune checkpoint inhibitors (ICIs) have revolutionised the treatment of metastatic NSCLC and have become standard first-line therapy both as monotherapy, for patients with PD-L1 expression ≥50%, and in combination with chemotherapy (CT), regardless of PD-L1 expression. This study used an artificial intelligence technique, the IPDfromKM method, to reconstruct individual patient data from Kaplan-Meier curves of phase III randomised clinical trial results to provide a comparative overview of different first-line chemo-immunotherapy options. Overall survival (OS) was estimated using hazard ratios and restricted mean survival time (RMST).

Gastrointestinal parasites in NHPs living in two zoological gardens of Northern Italy were studied. An total of 96 faecal pools were collected from 26 groups of NHPs.

Recently, numerous new treatments have been proposed to improve overall survival (OS) and reduce adverse effects, but no direct head-to-head comparisons among these agents are available.
Methods: The treatments evaluated in our analyses included (a) monotherapy with immune checkpoint inhibitors (ICI); (b) combinations of an ICI with chemotherapy; and (c) combinations of an ICI with other drugs.
The increase in scientific knowledge, oral healthcare, new dental hygiene workforce models, and the latest clinical skills, have elevated the need for doctoral prepared dental hygienists and dental therapists. These oral care providers need to be empowered with advanced preparation in education, research, and leadership. Therefore, the purpose of this paper is to present two curricular models for a doctorate of philosophy and a doctorate of oral health practice recognizing that students may have different goals and interests in educational pursuits.

Providing oral health care practitioners with an assessment and treatment protocol could facilitate the delivery of comprehensive oral health care. The purpose of this study was to test a protocol for assessing and treating patients with PCC in dental practice settings.

The aim of our study was to compare the efficacy of these treatments using an innovative method of reconstructing individual patient data.
Methods: Nine phase III trials describing adjuvant RCC treatments were selected.
Professional development is instrumental in the ongoing success of healthcare professionals and students. The purpose of the second year of this two-year study was to continue to apply the results from the CliftonStrengths assessment to support entry-level dental hygiene students' professional development and to create a conceptual model for professional development in dental hygiene education. CliftonStrengths were incorporated in didactic and community learning experiences throughout year two of the dental hygiene curriculum.

There is currently a lack of research about the efficacy and accuracy of manikin testing for clinical licensure. The purpose of this study is to identify perceptions of dental hygiene educators regarding the use of manikins for the dental hygiene clinical licensure exam.

Radiographically, the lesion appeared radiolucent and unilocular with well-defined borders and significant bone resorption. The area of radiolucency increased in size over a period of five weeks indicating an aggressive pathosis.

The purpose of the year one of a two-year study was to apply the results from a strengths assessment instrument to entry-level dental hygiene students' learning experiences and faculty instruction of students. An exploratory research design including quantitative and qualitative methods was used among a convenience sample of entry-level dental hygiene students.

Taking advantage of the unique physiology of the pulmonary circulation, here, micro-combinatorial hydrogel particles (µCGP) are realized via soft lithographic techniques to enhance the specific delivery of a cocktail of cytotoxic nanoparticles to metastatic foci. By cross-linking short poly(ethylene glycol) (PEG) chains with erodible linkers within a shape-defining template, a deformable and biodegradable polymeric skeleton is realized and loaded with a variety of therapeutic and imaging agents, including docetaxel-nanoparticles.

An immediate surgical intervention for frail patients who are ineligible for surgery as a result of severe co-morbidities is questionable. The aim of this study is to investigate the safety and the management of percutaneous cholecistostomy (PC) in high-risk surgical patients.

Materials And Methods: This study used a retrospective design to evaluate data from July 2018 to February 2020. The patient records were screened to determine whether patients received a periodontal diagnosis, whether the diagnosis followed the 2018 AAP Classification Guidelines, and if appropriate preventive and therapeutic procedures were completed in a timely manner.
