Exploring the clinical profiles and management of juvenile dermatomyositis in Africa: a survey of African rheumatology care providers.

Background: There are limited studies of juvenile dermatomyositis (JDM) in low and middle-income countries (LMIC). Many demonstrate delays to care, high prevalence of severe manifestations, and high mortality. Given the disease-associated damage with JDM, understanding JDM in Africa further is critical.

Transaxillary endovascular aortic aneurysm repair using a reverse mounted Gore Excluder endograft for a patient with abdominal aortic aneurysm and severe iliofemoral occlusive disease.

Adverse iliofemoral anatomy represents a unique challenge for endovascular aortic aneurysm repair (EVAR). This report describes a transaxillary EVAR in a patient with severe iliofemoral occlusive disease and an infrarenal aortic aneurysm. A reversely mounted Gore Excluder graft was advanced and deployed in the infrarenal aorta using the left axillary artery.

Electrophysiological Characterization of Monoolein-Fatty Acid Bilayers.

Understanding the evolution of protocells, primitive compartments that distinguish self from nonself, is crucial for exploring the origin of life. Fatty acids and monoglycerides have been proposed as key components of protocell membranes due to their ability to self-assemble into bilayers and vesicles capable of nutrient exchange. In this study, we investigate the electrophysiological properties of planar bilayers composed of monoglyceride and fatty acid mixtures, using a droplet interface bilayer system.

'This modern Cinderella': Railway Queens, mass media, and British civic culture, 1925-75.

Between 1925 and 1975, the British railway industry elected beauty queens from the daughters of employees. Focusing upon the Railway Queens, this article will reveal the importance of beauty queens as 'civic celebrities', a novel role for public figures that emerged between the wars and helped to sustain a vibrant civic culture across the early to mid-twentieth century. It combined the traditional ceremonial function of 'civic' representative with the modern consumerist ethos of media 'celebrity'.

Spatially restricted and ontogenically distinct hepatic macrophages are required for tissue repair.

Our understanding of the functional heterogeneity of resident versus recruited macrophages in the diseased liver is limited. A population of recruited lipid-associated macrophages (LAMs) has been reported to populate the diseased liver alongside resident Kupffer cells (KCs). However, the precise roles of these distinct macrophage subsets remain elusive.
