Objective

A role of microRNA, which are ∼22‐nucleotide noncoding RNAs, has recently been recognized in human diseases. The objective of this study was to identify the expression pattern of microRNA‐146a (miR‐146a) in cartilage from patients with osteoarthritis (OA).

Methods

The expression of miR‐146a in cartilage from 15 patients with OA was analyzed by quantitative reverse transcription–polymerase chain reaction (RT‐PCR) and by in situ hybridization. Induction of the expression of miR‐146a by cultures of normal human articular chondrocytes following stimulation with interleukin‐1β (IL‐1β) was examined by quantitative RT‐PCR.

Results

All cartilage samples were divided into 3 groups according to a modification of the Mankin score (grade I = mild OA scored 0–5, grade II = moderate OA scored 6–10, and grade III = severe OA scored 11–14). In grade I OA cartilage samples, the expression of miR‐146a and COL2A1 was significantly higher than that in the other groups (P < 0.05). In grades II and III OA cartilage, the expression of miR‐146a and COL2A1 was decreased, whereas the expression of matrix metalloproteinase 13 (MMP‐13) was elevated in grade II OA cartilage. These data showed that miR‐146a is expressed intensely in cartilage with a low Mankin grade and that miR‐146a expression decreases in parallel with the level of MMP‐13 expression. Tissue section in situ hybridization of primary miR‐146a (pri‐miR‐146a) revealed that pri‐miR‐146a was expressed in chondrocytes residing in all tissue layers, especially in the superficial layer, where it was intensely expressed. The expression of miR‐146 was markedly elevated by IL‐1β stimulation in human chondrocytes in vitro.

Conclusion

This study shows that miR‐146 is intensely expressed in low‐grade OA cartilage and that its expression is induced by stimulation of IL‐1β. Thus, miR‐146 might play a role in OA cartilage pathogenesis.
Anti–U3 RNP autoantibodies in systemic sclerosis
Authors: Aggarwal Rohit , Lucas Mary , Fertig Noreen , Oddis Chester V. , Medsger Thomas A.
Published: March 2009

Objective

To describe the classification, demographic and clinical features, and survival in anti–U3 RNP autoantibody–positive patients with systemic sclerosis (SSc).

Methods

Medical records of 108 anti–U3 RNP–positive and 2,471 anti–U3 RNP–negative SSc patients first evaluated during 1985–2003 were reviewed. Anti–U3 RNP antibody was detected by protein and RNA immunoprecipitation. Disease classification, demographic and clinical features, organ system involvement, and survival were compared between the 2 patient groups, by Student's t‐test, chi‐square analysis, and Mantel‐Haenszel test.

Results

The anti–U3 RNP–positive group had a higher proportion of African American patients (27% versus 5%; P < 0.001) and male patients (29% versus 19%; P = 0.021), and was younger at the time of first physician diagnosis (mean age 42.8 years versus 47.4 years; P = 0.001). The 2 groups had similar proportions of patients with diffuse cutaneous involvement (47% and 45% in those with and those without anti–U3 RNP, respectively). However, among patients with diffuse cutaneous involvement, the mean maximum modified Rodnan skin score was significantly lower in the anti–U3 RNP group (22.3 versus 27.9; P < 0.001). Skeletal muscle involvement was more frequent in anti–U3 RNP–positive patients (25% versus 14%; P = 0.002), as was “intrinsic” pulmonary arterial hypertension (PAH) (31% versus 13%; P < 0.001). The frequency of gastrointestinal involvement, cardiac involvement, pulmonary fibrosis, and “renal crisis” did not differ significantly between the 2 groups. Survival was worse in the anti–U3 RNP–positive group (hazard ratio 1.38 [95% confidence interval 1.05–1.82]). PAH was the most common known cause of death in patients with anti–U3 RNP (30%, versus 10% in the anti–U3 RNP–negative group; P < 0.001).

Conclusion

The present findings demonstrate that the frequencies of African American race and male sex are greater among SSc patients with anti–U3 RNP antibody than those without, and the former group is younger at SSc diagnosis. Anti–U3 RNP–positive patients have more frequent skeletal muscle involvement and PAH, the latter being the most common cause of death.
Extranodal lymphoid microstructures in inflamed muscle and disease severity of new‐onset juvenile dermatomyositis
Authors: López De Padilla Consuelo M. , Vallejo Abbe N. , Lacomis David , McNallan Kelly , Reed Ann M.
Published: March 2009

Objective

Juvenile dermatomyositis (DM) is an autoimmune disease of childhood characterized by lesions in skin and muscle that are populated by plasmacytoid dendritic cells (PDCs) and lymphocyte infiltrates. We undertook this study to examine the cellular composition, organization, and molecular milieu of the cellular infiltrates in muscle in juvenile DM and to correlate the infiltrates with clinical disease manifestations.

Methods

Since PDCs and lymphocyte foci express CCL19 and CCL21, we investigated for in situ formation of lymphoid microstructures that could be sites of extranodal immune activation.

Results

Analyses of muscle biopsy samples from children with new‐onset juvenile DM showed 3 categories of lesions: diffuse infiltrates, lymphocytic aggregates lacking follicle‐like organization, and follicle‐like structures. The last of these exhibited elements of classic lymphoid follicles, including networks of follicular dendritic cells and high endothelial venules. They also expressed high levels of CXCL13 and lymphotoxins known to support lymphoid organogenesis. There were also resident naive CD45RA+ T cells and maternally derived B cells and PDCs. Patients with diffuse infiltrates or lymphocytic aggregates were responsive to standard therapy with steroids and methotrexate, but those with follicle‐like structures tended to have severe disease that required additional agents such as intravenous Ig or rituximab.

Conclusion

These data suggest that lymphoneogenesis is a component of the early disease process in juvenile DM. Ectopic lymphoid structures could indicate a severe course of disease; their early detection could be a tool for disease management.
Is 18F‐fluorodeoxyglucose positron emission tomography scanning a reliable way to assess disease activity in takayasu arteritis?

Published: March 2009

Objective

18F‐fluorodeoxyglucose–positron emission tomography (FDG‐PET) scanning has been proposed as a new way of assessing disease activity in Takayasu arteritis (TA), but previous studies have used the nonvalidated National Institutes of Health (NIH) global activity criteria, and thus might be biased. This study was undertaken to determine the value of PET scanning for assessment of disease activity in TA, by comparing PET scan data with clinical, biologic, and magnetic resonance imaging (MRI) data assessed separately.

Methods

Twenty‐eight patients with TA (according to the American College of Rheumatology criteria) underwent a total of 40 PET scans. Images were reviewed by 2 pairs of independent nuclear medicine physicians and assessed for pattern and intensity of vascular uptake. TA activity data were obtained within 15 days of the PET scans.

Results

PET scanning revealed abnormal vascular uptake in 47% of the 40 examinations. The uptake intensity grade was 0 in 7 scans, grade 1 in 7 scans, grade 2 in 13 scans, and grade 3 in 13 scans. Morphologic analysis was conducted by grading the pattern of the vascular uptake as diffuse (73%), segmental (20%), or focal (13%). There was a trend toward an association between clinically active disease and the semiquantitative assessment of FDG uptake (P = 0.08). We found no statistical association between levels of acute‐phase reactants and intensity of uptake. There was no significant association between the semiquantitative assessment of FDG uptake and the presence of vascular wall thickening (P = 0.23), gadolinium uptake (P = 0.73), or the presence of vascular wall edema (P = 0.56).

Conclusion

Our findings indicate that there is no association between FDG vascular uptake intensity and clinical, biologic, or MRI assessment of disease activity. Previous studies using the nonvalidated NIH global activity criteria are likely biased.
The impact of gross anatomy on the future head and neck surgeon
Authors: Archibald David J. , Carlson Matthew L.
Published: April 2009

Gross anatomy is not only a rite of passage for medical students as they enter the world of practicing medicine but may also be an unrecognized fork in the road in their pursuit of choosing a medical specialty. Otolaryngology: head and neck surgery tends to be poorly represented in medical school curriculum, often only offered as an elective rotation. However, head and neck anatomy remains a constant in most medical schools, granting some exposure to otolaryngology whether students realize it or not. A common thread among most head and neck surgeons in their decision to pursue this surgical specialty is a love for head and neck anatomy, spawned in that first year gross anatomy course. This first and potentially only exposure to otolaryngology should be optimized, as it can have a profound effect in the selection of otolaryngology as a specialty. This introduction can be facilitated by (1) inviting otolaryngology residents to assist during the dissection of the head and neck, (2) soliciting otolaryngology attending physicians to provide clinical correlation lectures, and (3) anatomy professors should identify students who excel in the head and neck portion of the curriculum and direct them towards otolaryngology mentors. There may be a great missed opportunity if a career in otolaryngology is not discussed with students during the dissection of the head and neck.

Der Beitrag von Profilblechdecken zur passiven Kühlung
Authors: Döring Bernd , Feldmann Markus , Kuhnhenne Markus
Published: April 2009

Die Ausnutzung der thermischen Speichermasse eines Gebäudes zur Beeinflussung der Raumtemperaturen bzw. zur Reduzierung des Energieverbrauchs war in der Vergangenheit Gegenstand zahlreicher Forschungsvorhaben. Um den Einfluss der Speichermasse ermitteln zu können, werden häufig thermische Gebäudesimulationsprogramme eingesetzt, aber auch die aktuelle Fassung von DIN V 18599 berücksichtigt die Wirkung der Wärmekapazität der raumumfassenden Flächen. Sowohl bei Anwendung von DIN V 18599 als auch bei der Gebäudesimulation geht man dabei von einer eindimensionalen Schichtenfolge für Wände und Decken aus. Es gibt jedoch Bauteile, wie z. B. Profilblechdecken, bei denen diese Annahme nicht zutreffend ist. In diesem Bericht werden nun über die Auswertung dynamischer FEM‐Berechnungen für inhomogene Deckenaufbauten Ersatzgrößen bestimmt, so dass die Definition einer thermisch äquivalenten Decke als eindimensionales Modell möglich ist. Für ausgewählte Beispiele wird die Wirksamkeit dieser Decken hinsichtlich ihrer Wärmeaufnahme und ‐abgabe untersucht.
Ermittlung des Wasserdampfdiffusionswiderstandes von Baustoffen in Abhängigkeit von der Baustofftemperatur
Authors: Pötzsch Nicol , Rüther Norbert
Published: April 2009

Analog zu dem in DIN EN ISO 12572 beschriebenen Messverfahren zur Ermittlung des Wasserdampfdiffusionswiderstandswertes μ von Baustoffen, wurden Untersuchungen zum Einfluss der Temperatur auf den Diffusionswiderstand durchgeführt. Die Untersuchungen erfolgten sequenziell bei ausgewählten Temperaturstufen von –10, –5, 0, 10 sowie 50 °C. Untersucht wurden zwei Holzwerkstoffe (MDF, OSB), ein Wärmedämm‐Verbundsystem, ein Putzsystem und ein EPS‐Dämmstoff. Anhand der Ergebnisse kann darauf geschlossen werden, dass die Temperatur innerhalb der untersuchten Grenzen einen Einfluss auf den Materialkennwert μ hat.
How Does the Axial Ligand of Cytochrome P450 Biomimetics Influence the Regioselectivity of Aliphatic versus Aromatic Hydroxylation?
Authors: de Visser Sam P. , Tahsini Laleh , Nam Wonwoo
Published: April 2009

How deep is your orbital? Density functional theory studies on the axial ligand effect of aliphatic versus aromatic hydroxylation of ethylbenzene by iron–oxo complexes with a variable axial ligand show that strong (anionic) ligands pull the metal inside the plane of the haeme and destabilise cationic intermediates through orbital interactions (see picture).

magnified image

The catalytic activity of high‐valent iron–oxo active species of heme enzymes is known to be dependent on the nature of the axial ligand trans to the iron–oxo group. In a similar fashion, experimental studies on iron–oxo porphyrin biomimetic systems have shown a significant axial ligand effect on ethylbenzene hydroxylation, with an axial acetonitrile ligand leading to phenyl hydroxylation products and an axial chloride anion giving predominantly benzyl hydroxylation products. To elucidate the fundamental factors that distinguish this regioselectivity reversal in iron–oxo porphyrin catalysis, we have performed a series of density functional theory calculations on the hydroxylation of ethylbenzene by [FeIVO(Por+.)L] (Por=porphyrin; L=NCCH3 or Cl−), which affords 1‐phenylethanol and p‐ethylphenol products. The calculations confirm the experimentally determined product distributions. Furthermore, a detailed analysis of the electronic differences between the two oxidants shows that their reversed regioselectivity is a result of differences in orbital interactions between the axial ligand and iron–oxo porphyrin system. In particular, three high‐lying orbitals (π*xz, π*yz and a2u), which are singly occupied in the reactant complex, are stabilised with an anionic ligand such as Cl−, which leads to enhanced HOMO–LUMO energy gaps. As a consequence, reactions leading to cationic intermediates through the two‐electron reduction of the metal centre are disfavoured. The aliphatic hydroxylation mechanism, in contrast, is a radical process in which only one electron is transferred in the rate‐determining transition state, which means that the effect of the axial ligand on this mechanism is much smaller.
