Diagnostic Use of Testing for Novel Murine Autoantibodies for Sjögren Disease in the Rheumatology Outpatient Setting

open access: yesArthritis Care &Research, EarlyView.
Objective The goal was to assess the diagnostic performance of three novel autoantibodies (NA) for Sjögren disease (SjD) by comparing NA prevalence in patients with SjD, other autoimmune rheumatic diseases (ARDs), nonspecific chronic sialadenitis (CS), and controls.

Determination of carbon-carbon connectivities, assignment of quaternary carbons, and extraction of carbon-carbon coupling constants by carbon-relayed hydrogen-carbon spectroscopy

open access: yesJournal of Magnetic Resonance (1969), 1985
Nowadays many possibilities exist to elucidate carbon-carbon connectivity. In hydrogen-bearing carbon systems C-C connectivities can be traced out most conveniently in an indirect way by a combination of H-H COSY (I) and H-C CQSY (2). In case of overlapping ‘proton signals ambiguities can be removed by heteronuclear relayed spectroscopy (3) and ...

MYCOPHENOLATE MOFETIL TREATMENT REDUCES THE RISK OF TREATMENT ESCALATION DUE TO VASCULAR COMPLICATIONS IN LIMITED CUTANEOUS SYSTEMIC SCLEROSIS: EMULATION OF A TARGET TRIAL FROM ITALIAN RHEUMATOLOGY SOCIETY SPRING REGISTRY

open access: yesArthritis Care &Research, Accepted Article.
Objective Mycophenolate Mofetil (MMF) use in limited cutaneous systemic sclerosis (lcSSc) is relatively uncommon due to the lower fibrotic burden and the predominance of the vascular complications. In vitro observations and clinical data from transplanted patients suggest a protective effect of MMF on endothelial function.

p-Nitrophenyl carbonate promoted ring-opening reactions of DBU and DBN affording lactam carbamates

open access: yesBeilstein Journal of Organic Chemistry, 2016
The amidine bases DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) and DBN (1,5-diazabicyclo[4.3.0]non-5-ene) display nucleophilic behaviour towards highly electrophilic p-nitrophenyl carbonate derivatives with ring opening of the bicyclic ring to form ...

Formulated and unformulated carbonates to control apple scab (Venturia inaequalis) on organic apple [PDF]

open access: yes, 2008
In the EC at the moment only copper- and sulphur-based products are allowed to control a variety of diseases on different crops. However, it is well-known that these products also have negative side effects on beneficial organisms and the soil.

Cellulose carbon-CVD carbon composites

open access: yesCarbon, 1975
Carbon-carbon composites have been fabricated using a cellulose powder which is molded at low pressures, carbonized at 800°C and infiltrated by a CVD technique at 700°C using propylene as a source of carbon. Infiltration rate at time t is governed by the amount of open porosity existing in the sample at this time.

Marked Long‐Term Improvement in Lung Function in Melanoma Differentiation–Associated Protein 5 Antibody–Positive Dermatomyositis Patients: Experience of a Single‐Center Longitudinal Cohort in North America

open access: yesArthritis Care &Research, EarlyView.
Objective The objective of this study was to describe the longitudinal disease course and pulmonary outcomes of North American patients with melanoma differentiation–associated protein 5 (MDA5) antibody–associated dermatomyositis (DM). Methods Thirty patients with MDA5 antibody–associated DM were identified in a single‐center longitudinal cohort of 352
