Rescue Treatment with Infliximab for a Bilateral, Severe, Sight Threatening Frosted Branch Angiitis Associated with Concomitant Acute Onset of Presumed Dermatomyositis.

Purpose: To report a severe bilateral frosted branch angiitis associated with acute onset of systemic dermatomyositis.

Method: History and clinical examination, laboratory evaluation, fundus' and skin's color pictures, fluorescein angiography (FA), optical coherence tomography (OCT).

Results: A 32-year-old female was referred for a bilateral frosted branch angiitis and vitreitis, with skin rash, muscle pain, weakness, severe headache, compatible with dermatomyositis.

Evaluating the chemical exfoliation of lithium cobalt oxide using UV-Vis spectroscopy.

Two-dimensional materials have been at the forefront of chemistry and materials science research for the past decade owing to promising applications across many fields. Improvements in exfoliation processes continually give access to new two-dimensional material compositions, demanding a deeper understanding of the defect structure and exfoliation mechanisms. Chemical exfoliation processes allow for both the fabrication of new, and the production of industrial-scale quantities of two-dimensional materials.

Education and Intelligence: Pity the Poor Teacher because Student Characteristics are more Significant than Teachers or Schools.

Education has not changed from the beginning of recorded history. The problem is that focus has been on schools and teachers and not students. Here is a simple thought experiment with two conditions: 1) 50 teachers are assigned by their teaching quality to randomly composed classes of 20 students, 2) 50 classes of 20 each are composed by selecting the most able students to fill each class in order and teachers are assigned randomly to classes.

Mentoring international research ethics trainees: identifying best practices.

Mentoring is an important component of training in the basic and clinical sciences due to the increasing complexities associated with establishing a career. Data relating to 466 long-term trainees in research ethics training programs were obtained from the Fogarty International Center's database. Data were supplemented with survey data (n = 17) and telephone interviews (n = 10) of the 21 principal investigators whose programs offered long-term training.

Is there a universal understanding of vulnerability? Experiences with Russian and Romanian trainees in research ethics.

Vulnerability of participants in research and the provision of special protections for vulnerable research participants are key concepts in research ethics. Despite international consensus requiring special protections for vulnerable research participants, both the concept of vulnerability and the nature and adequacy of strategies to reduce vulnerability remain vague and, consequently, are subject to varying interpretations. We report on observations of the challenges faced in understanding this key concept by 20 Russian and Romanian trainees participating in a one-year M.
