BACKGROUND Alopecia Areata (AA) is a disease characterized by hair loss that is widely believed to be autoimmune in origin. Thus treatment is generally aimed in this direction using immune inhibitors such as steroids and PUVA. OBJECTIVE To describe a variant of AA, Pseudo Alopecia Areata, caused by a particular cupola pin holder (tic-tac) and to offer a non-pharmacological treatment option (N...

Abstract Objectives To reduce the spread of infection, especially during aerosol generating procedures, we invented “The Cupola”, a shield that creates mechanical barrier around patient’s head and body. With this pilot study aimed to assess effectiveness an additional layer protection (The Cupola) developed for providers working in oropharyngeal region. Results The mean number 0.3 μm particles ...

The cupola is a furnace used for melting steel scrap, cast iron scrap, and ferroalloys to produce cast iron. Its main energy source is coal coke. It is one of the oldest methods of producing cast iron, and it remains the dominate method because of its simplicity and low fuel cost. Cupolas range in size from 18 inches to 13 feet in diameter, and can produce up to 100 tons per hour of cast iron. ...

Our study sought to determine whether the size of the residual apical pleural space in young patients with primary spontaneous pneumothorax (PSP) following video-assisted thoracoscopic surgery is associated with the risk of recurrence. We retrospectively reviewed patients (≤30 years' old) with primary spontaneous pneumothorax following thoracoscopic surgery (2002-2010) in a university-affiliate...

Parasites and parasitoids control behaviors of their hosts. However, the origin of the behavior evoked by the parasitic organism has been rarely identified. It is also not known whether the manipulation is universal or host-specific. Polysphinctine wasps, koinobiont ectoparasitoids of several spider species that manipulate host web-spinning activity for their own protection during pupation, pro...

In this work we investigate by means of atomic force microscopy in combination with selective wet etching experiments coalescence and coarsening effects on the morphology evolution of Si-rich SiGe quantum dots and islands grown epitaxially at high temperatures on Si(001) substrates. We demonstrate that under certain growth conditions remarkably uniform island size distributions can be achieved ...
