Hairy Tongue

Hairy tongue (lingua villosa) is a commonly observed condition of defective desquamation of the filiform papillae that results from a variety of precipitating factors. [1] The condition is most frequently referred to as black hairy tongue (lingua villosa nigra); however, hairy tongue may also appear brown, white, green, pink, or any of a variety of hues depending on the specific etiology and secondary factors (eg, use of colored mouthwashes, breath mints, candies).

The Politics of Islam in Europe and North America

There has traditionally been a wide divide between the study of the politics of Islam in the Middle East and in the West. Middle East-focused research in American political science has focused in great depth on issues such as political mobilization, social service provision, electoral performance, and Islamist ideologies. American research on Islam in the West, by contrast, has often focused on cultural conflicts, immigration, terrorism, and anti-Islamic campaigns. Today’s European scholarship on Islam distinguishes itself by a wide spectrum of methods, topics, and fieldworks, with a trend toward strong ethnographic research. Over the last two decades, a prolific and pluralist field of scholarship on Islam and Muslims in Europe and the U.S. has emerged and brought to the fore innovative perspectives and understudied topics. On June 28, 2018, POMEPS and Sciences Po CERI convened a workshop with a dozen scholars of Islam and politics in Europe and North America to engage with these various perspectives. Their work in POMEPS Studies 32: The Politics of Islam in Europe and North America illustrates the richness of the field of the politics of Islam in Europe and the U.S.Introduction, Marc Lynch, Nadia Marzouki French Muslim authorities as social troubleshooters, Margot Dazey What makes “Muslim representatives” representative?

Application of tandem two-dimensional mass spectrometry for top-down deep sequencing of calmodulin

Two-dimensional mass spectrometry (2DMS) involves simultaneous acquisition of the fragmentation patterns of all the analytes in a mixture by correlating their precursor and fragment ions by modulating precursor ions systematically through a fragmentation zone. Tandem two-dimensional mass spectrometry (MS/2DMS) unites the ultra-high accuracy of Fourier transform ion cyclotron resonance (FT-ICR) MS/MS and the simultaneous data-independent fragmentation of 2DMS to achieve extensive inter-residue fragmentation of entire proteins. 2DMS was recently developed for top-down proteomics (TDP), and applied to the analysis of calmodulin (CaM), reporting a cleavage coverage of about ~23% using infrared multiphoton dissociation (IRMPD) as fragmentation technique. The goal of this work is to expand the utility of top-down protein analysis using MS/2DMS in order to extend the cleavage coverage in top-down proteomics further into the interior regions of the protein. In this case, using MS/2DMS, the cleavage coverage of CaM increased from ~23% to ~42%

Endovascular Embolization of Head and Neck Tumors

Endovascular tumor embolization as adjunctive therapy for head and neck cancers is evolving and has become an important part of the tools available for their treatment. Careful study of tumor vascular anatomy and adhering to general principles of intra-arterial therapy can prove this approach to be effective and safe. Various embolic materials are available and can be suited for a given tumor and its vascular supply. This article aims to summarize current methods and agents used in endovascular head and neck tumor embolization and discuss important angiographic and treatment characteristics of selected common head and neck tumors

Asynchronous accretion can mimic diverse white dwarf pollutants II: water content

Volatiles, notably water, are key to the habitability of rocky planets. The presence of water in planetary material can be inferred from the atmospheric oxygen abundances of polluted white dwarfs, but this interpretation is often complex. We study the accretion process, and find that ices may sublimate and accrete before more refractory minerals reach the star. As a result, a white dwarf's relative photospheric abundances may vary with time during a single accretion event, and do not necessarily reflect the bulk composition of a pollutant. We offer two testable predictions for this hypothesis: 1. cooler stars will more often be inferred to have accreted wet pollutants, and 2. there will be rare occurrences of accretion events with inferred volatile levels far exceeding those of pristine comets. To observationally test these predictions, we statistically constrain the water content of white dwarf pollutants. We find that in the current sample, only three stars show statistically significant evidence of water at the 2$\sigma$ level, due to large typical uncertainties in atmospheric abundances and accretion states. In the future, an expanded sample of polluted white dwarfs with hydrogen-dominated atmospheres will allow for the corroboration of our theoretical predictions. Our work also shows the importance of interpreting pollutant compositions statistically, and emphasizes the requirement to reduce uncertainties on measured abundances to allow for statistically significant constraints on their water content.Comment: Accepted for publication in MNRAS.
