BACKGROUND: Articular erosions correlate with disability in rheumatoid arthritis (RA). Biologic treatments for RA reduce erosion progression, but erosion healing occurs infrequently. The goal of this study was to assess the effects of the anabolic agent teriparatide on joint erosion volume in RA patients treated with a tumor necrosis factor inhibitor (TNFi). METHODS: We conducted a randomized controlled trial in 24 patients with erosive RA, osteopenia, and disease activity controlled on a TNFi for at least three months...

BACKGROUND: Food allergies pose a considerable world-wide public health burden with incidence as high as one in ten in 12-month-old infants. Few food allergy genetic risk variants have yet been identified. The Th2 immune gene IL13 is a highly plausible genetic candidate as it is central to the initiation of IgE class switching in B cells. OBJECTIVE: Here, we sought to investigate whether genetic polymorphisms at IL13 are associated with the development of challenge-proven IgE-mediated food allergy...

Belatacept, a T cell costimulation-blocker demonstrated superior renal function, lower cardiovascular risk, and improved graft/patient survival in renal transplant recipients. Despite the potential benefits, adoption of belatacept has been limited in part due to concerns regarding higher rates and grades of acute rejection in clinical trials. Since July 2011 we have utilized belatacept-based immunosuppression regimens in clinical practice. In this retrospective analysis of 745 patients undergoing renal transplantation at our center, we compared patients treated with belatacept (n=535) to a historical cohort receiving a tacrolimus-based protocol (n=205)...

It is presented a detailed quantum chemical study analyzing the mechanism of ethylene oligomerization and polymerization by means of a family of four neutral methallyl NiII catalysts. The role of the boron co-activators [BF₃ or B(C₆F₅)₃] and ligand functionalization (in ortho or para position of the N-arylcyano moiety of the catalysts) was investigated to explain the chain length of the obtained polymers. The chain initialization proceeds with higher activation barriers for the ortho functionalized complexes (19 kcal mol¯¹) compared to the para isomers (17-18 kcal mol¯¹)...

BACKGROUND/OBJECTIVES: U.S. adults and children are equally likely to have allergic contact dermatitis. Historically the narrow geographic location of data-reporting providers has quantitatively and qualitatively limited the pediatric contact dermatitis data. The Pediatric Contact Dermatitis Registry was used to evaluate self-identified pediatric patch test providers within the United States with regard to demographic characteristics, geographic location, and practice patterns. METHODS: A wide range of U...

Fractures are common in otherwise healthy children and adolescents. They result from trauma of varying severity. Some reflect a greater skeletal fragility. A long-term implication of these fractures is their potentiality to predict adult bone fragility and increased risk of osteoporosis in later life. Using DXA, HR-pQCT and µFEA measurements, we previously found in 124 healthy females followed from the age of 7.9 to 20.4 years, substantial deficits in both structural and strength components of the radius in the 42 girls who sustained a fracture during skeletal development...

Induction of the detoxifying enzyme heme oxygenase-1 (HO-1) is a critical protective host response to cellular injury associated with inflammation and oxidative stress. We previously found that HO-1 protein expression is reduced in brains of HIV-infected individuals with HIV-associated neurocognitive disorders (HAND) and in HIV-infected macrophages, where this reduction associates with enhanced glutamate release and neurotoxicity. Because HIV-infected macrophages are a small component of the cellular content of the brain, the reduction of macrophage HO-1 expression likely accounts for a small portion of brain HO-1 loss in HIV infection...

OBJECTIVE: There is a need for inexpensive non-invasive tests to identify older healthy persons at risk for Alzheimer's disease (AD) for enrollment in AD prevention trials. Our objective was to examine whether abnormalities in neuroimaging measures of amyloid and neurodegeneration are correlated with odor identification (OI) in the population-based Mayo Clinic Study of Aging (MCSA). METHODS: Cognitively normal (CN) participants had olfactory function assessed using the Brief Smell Identification Test (B-SIT), underwent magnetic resonance imaging (MRI; n=829) to assess a composite Alzheimer's disease (AD) signature cortical thickness and hippocampal volume (HVa), and, (11) C-Pittsburgh compound B ((11) C-PiB; n=306) and (18) fluorodeoxyglucose ((18) F-FDG; n=305) positron emission tomography (PET) scanning to assess amyloid accumulation and brain hypometabolism, respectively...

Disseminated superficial actinic porokeratosis (DSAP), the most common type of porokeratosis, usually presents as large numbers of lesions on sun-exposed skin. Although several treatment options including corticosteroids, keratolytics, 5-fluorouracil, imiquimod, vitamin D3 analogues, cryotherapy, curettage, laser therapy and dermabrasion may be considered, there is no evidence-based standard treatment.(1-2) Patient 1 was a 26-year-old female who presented with a 2-year history of progressive scaly macules on both upper and lower extremities...

Liver fibrosis is common, particularly in human immunodeficiency virus infected (HIV+) people. HIV+ people have excess congestive heart failure (CHF) risk compared to uninfected people. It remains unknown if stage of liver fibrosis influences the CHF risk or if HIV or hepatitis C virus (HCV) infection modifies this association. Our objectives were to assess whether: 1) stage of liver fibrosis is independently associated with incident CHF; 2) the association between stage of liver fibrosis and incident CHF is modified by HIV/HCV status...

AIM: To evaluate the effect of ultrasonic and sonic activation of two root canal sealers on interfacial adaptation and push-out bond strength (BS) to root canal dentine. METHODOLOGY: The root canals of seventy-eight roots of maxillary canines was prepared with Ni-Ti rotary instruments under irrigation with 2.5% NaOCl and 17% EDTA. Canals were filled by lateral condensation of gutta-percha and AH Plus (n=39) or MTA Fillapex (n=39). Three subgroups (n=13) were formed according to sealer activation: no activation (NA), sonic activation (SA, 20 s) and ultrasonic activation (US, 20 s)...

Using Nogo antibodies with defined binding specificity, Nogo-B, but not Nogo-A, was localized on radial glia in the floor plate of mouse embryos. The presence of Nogo-B was confirmed in Nogo-A knockout mice. In explant cultures of embryonic day (E) 11 and E12 spinal cord, blocking of NgR function with antagonist peptide NEP1-40 reduced the crossing of newly arrived commissural axons, resulting in an accumulation of growth cones in the floor plate. Analysis of growth cone morphology demonstrated an increase in size of growth cones in the floor plate after peptide treatment, which was not detected in axons growing towards the midline...

GPR40 (FFA1) is a fatty acid receptor whose activation results in potent glucose lowering and insulinotropic effects in vivo. Several reports illustrate that GPR40 agonists exert glucose lowering in diabetic humans. To assess the mechanisms by which GPR40 partial agonists improve glucose homeostasis, we evaluated the effects of MK-2305, a potent and selective partial GPR40 agonist, in diabetic Goto Kakizaki rats. MK-2305 decreased fasting glucose after acute and chronic treatment. MK-2305-mediated changes in glucose were coupled with increases in plasma insulin during hyperglycemia and glucose challenges but not during fasting, when glucose was normalized...
