OBJECTIVE: Rheumatoid arthritis (RA) causes destruction of the metacarpophalangeal (MCP) joints leading to hand deformities, pain, and loss of function. This study prospectively assessed long-term functional and health-related quality of life outcomes in RA patients with severe deformity at the MCP joints. METHODS: RA patients between the ages of 18-80 with severe deformity at the MCP joints were referred to one of the three study sites. Subjects who elected to undergo silicone metacarpophalangeal joint arthroplasty (SMPA) while continuing with medical management were followed in the SMPA cohort...

OBJECTIVES: Growing evidences show a direct link between inflammation and activation of haemostasis. That could increase thrombotic and cardiovascular risk in patients with active autoimmune diseases such as rheumatoid arthritis (RA) and systemic sclerosis (SSc). The aim of this study was to evaluate a possible hypercoagulable condition in RA and SSc patients, using the thrombin generation assay (TGA). METHODS: TGA was assessed in 44 RA [33 with active disease (actRA) and 11 inactive (non-actRA)], 25 SSc patients and 41 healthy controls using a fluorimetric technique and the TGA RB Low reagent...

For children with dyslexia, learning to write constitutes a great challenge. There has been consensus that the explanation for these learners' delay is related to a phonological deficit. Results from studies designed to describe dyslexic children's spelling errors are not always as clear concerning the role of phonological processes as those found in reading studies. In irregular languages like French, spelling abilities involve other processes than phonological processes. The main goal of this study was to describe the relative contribution of these other processes in dyslexic children's spelling ability...

BACKGROUND: Swan-neck deformity (SND) of the fingers can cause major functional impairment. The Zancolli-Tonkin procedure is a crossed dynamic tenodesis that prevents overextension of the proximal interphalangeal (PIP) joint and promotes extension of the distal interphalangeal (DIP) joint. We assessed the outcomes of this procedure in patients with SND due to various causes. HYPOTHESIS: The Zancolli-Tonkin procedure provides effective and stable correction of SND due not only to RA, but also to other conditions...

Primary Sjögren's syndrome (pSS) is a complex autoimmune disorder. So far, genetic research in pSS has lagged far behind and the underlying biological mechanism is unclear. Further exploring existing genome-wide association study (GWAS) data is urgently expected to uncover disease-related gene combination patterns. Herein, we conducted a network-based analysis by integrating pSS GWAS in Han Chinese with a protein-protein interactions network to identify pSS candidate genes. After module detection and evaluation, 8 dense modules covering 40 genes were obtained for further functional annotation...

BACKGROUND The exact role of shunting during carotid endarterectomy remains controversial and unclear. The aim of this experimental study was to investigate to what degree carotid clamping may induce changes in the cerebral oxidative status and to focus on the relation of these changes with shunt insertion. MATERIAL AND METHODS Forty New-Zealand rabbits were randomized into 4 groups: group 1 classifying animals with carotid shunt and patent contralateral carotid artery; group 2 shunt and occlusion of the contralateral carotid artery; group 3 no-shunt and patent contralateral carotid artery; and group 4 no-shunt and occlusion of the contralateral carotid artery...

The increased risk of cardiovascular disease (CVD) in rheumatoid arthritis (RA) has been recognized for many years. However, although the characteristics of CVD and its burden resemble those in diabetes, the focus on cardiovascular (CV) prevention in RA has lagged behind, both in the clinical and research settings. Similar to diabetes, the clinical picture of CVD in RA may be atypical, even asymptomatic. Therefore, a proactive screening for subclinical CVD in RA is warranted. Because of the lack of clinical trials, the ideal CVD prevention (CVP) in RA has not yet been defined...

OBJECTIVE: To examine the association of socioeconomic status (SES) and delays in disease-modifying antirheumatic drug (DMARD) treatment with clinical measures in rheumatoid arthritis (RA) patients. METHODS: RA patients were recruited from rheumatology practices. We assessed SES based on education, occupation, and income, and divided patients into tertiles. The time from RA symptom onset to DMARD initiation (DMARD lag) was determined by self-report of the 2 dates, and distance to the rheumatologist (Distance) was obtained from Google Maps...

OBJECTIVE: Previous studies assessing seasonal variation of relapse onset in multiple sclerosis have had conflicting results. Small relapse numbers, differing diagnostic criteria, and single region studies limit the generalizability of prior results. The aim of this study was to determine whether there is a temporal variation in onset of relapses in both hemispheres and to determine whether seasonal peak relapse probability varies with latitude. METHODS: The international MSBase Registry was utilized to analyze seasonal relapse onset distribution by hemisphere and latitudinal location...

Reproductive biotechnologies such as in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT) enable improved reproductive efficiency of animals. However, the birth rate of in vitro-derived embryos still lags behind that of their in vivo counterparts. Thus, it is critical to develop an accurate evaluation and prediction system of embryo competence, both for commercial purposes and for scientific research. Previous works have demonstrated that in vitro culture systems induce alterations in the relative abundance (RA) of diverse transcripts and thus compromise embryo quality...

Aptamers are nucleic acid based molecular recognition elements with a high potential for the theranostics. Some of the aptamers are under development for therapeutic applications as promising antithrombotic agents; and G-quadruplex DNA aptamers, which directly inhibit the thrombin activity, are among them. RA-36, the 31-meric DNA aptamer, consists of two thrombin binding pharmacophores joined with the thymine linker. It has been shown earlier that RA-36 directly inhibits thrombin in the reaction of fibrinogen hydrolysis, and also it inhibits plasma and blood coagulation...

The functional equilibrium between roots and shoots suggests an intrinsic linkage between belowground and aboveground phenology. However, much less understanding of belowground phenology hinders integrating belowground and aboveground phenology. We measured root respiration (Ra) as a surrogate for root phenology and integrated it with observed leaf phenology and radial growth in a birch (Betula platyphylla)-aspen (Populus davidiana) forest and an adjacent larch (Larix gmelinii) forest in Northeast China. A log-normal model successfully described the seasonal variations of Ra and indicated the initiation, termination and peak date of root phenology...
