The objective of the study was, with multidetector computed tomography (CT) as the reference method, to determine whether bone erosions in rheumatoid arthritis (RA) metacarpophalangeal (MCP) joints detected with magnetic resonance imaging (MRI) and ultrasonography (US), but not with radiography, represent true erosive changes. We included 17 RA patients with at least one, previously detected, r...

The development of rills on a hillslope whose soil is amended by biochar remains topic to be developed. A theoretical rill flow resistance equation, obtained the integration power velocity distribution, was assessed using available measurements at plot scale with added soil. incorporated and mixed arable content BC 6 12 kg m−2. developed analysis demonstrated that an accurate estimate profile p...

This issue of Sleep Science contains two excellent review articles by Garcia-Rill and his colleagues examining the role of reticular activating system, especially the pedunculopontine (PPT) nucleus, in the pathophysiology of insomnia, schizophrenia, and other neuropsychiatric disorders [1,2]. The PPT nucleus is one of the major aggregations of cholinergic neurons in the mammalian brainstem capa...

The aim of this study was to demonstrate the ability of conventional radiography to detect bone erosions of different sizes in metacarpophalangeal (MCP) joints of rheumatoid arthritis (RA) patients using magnetic resonance imaging (MRI) as the standard reference. A 0.2 T Esaote dedicated extremity MRI unit was used to obtain axial and coronal T1-weighted gradient echo images of the dominant 2nd...

We read with interest the pictorial essay on ultrasonography of bone erosions by Grassi and colleagues. The presented site-specific comparison of radiographic and sonographic imaging of metacarpophalangeal (MCP) and metatarsophalangeal (MTP) joint sites in rheumatoid subjects suggests strongly a homology of the erosive lesions, as visualised by these diVerent imaging modalities. A recently publ...
