BACKGROUND: Butterflies of the subtribe Mycalesina have radiated successfully in almost all habitat types in Africa, Madagascar, the Indian subcontinent, Indo-China and Australasia. Studies aimed at understanding the reasons behind the evolutionary success of this spectacular Old World butterfly radiation have been hampered by the lack of a stable phylogeny for the group. Here, we have reconstruct
Context: Low birth weight (LBW) and unhealthy diets are risk factors of metabolic disease including type 2 diabetes (T2D). Genetic, nongenetic, and epigenetic data propose a role of the key metabolic regulator peroxisome proliferator-activated receptor gamma, coactivator 1alpha (PPARGC1A) in the development of T2D. Objective: Our objective was to investigate gene expression and DNA methylation of
Background and purpose: Statin treatment may ameliorate viral infection-induced exacerbations of chronic obstructive pulmonary disease (COPD), which exhibit Th2-type bronchial inflammation. Thymic stromal lymphopoietin (TSLP), a hub cytokine switching on Th2-inflammation, is overproduced in viral and dsRNA-stimulated bronchial epithelial cells from COPD donors. Hence, TSLP may be causally involve
STUDY DESIGN: Retrospective study. OBJECTIVES: To optimize the radiation doses and image quality for the cone-beam O-arm surgical imaging system in spinal surgery. SUMMARY OF BACKGROUND: Neurovascular compromise has been reported after screw misplacement during thoracic pedicle screw insertion. The use of O-arm with or without navigation system during spinal surgery has been shown to lower the rat
OBJECTIVE: To identify factors predicting response to first TNF blocking treatment course in patients with established RA with a special focus on gender differences. METHODS: Patients with active RA initiating their first treatment course of TNF-blocking therapy were enrolled. The study period was March 1999 through September 2006. The prospective protocol included information on demographics, cli
Background: Low-grade fibromyxoid sarcoma (LGFMS) is an uncommon neoplasm with bland morphology and an indolent clinical course, although metastases may develop in approximately 5-10% of the cases. The diagnosis of LGFMS can be difficult to render from fine needle aspiration cytology (FNAC) alone because of morphological overlap with other spindle cell and myxoid lesions. Objective: To determine c
Structural compromise of the tumor suppressor gene, PTEN occurs in 10% of melanoma specimens and loss of PTEN expression through DNA methylation of the PTEN promoter region has also been reported in a number of other malignancies. However, the role of PTEN promoter methylation in melanoma is not well understood. We thus sought to elucidate the prevalence of PTEN promoter methylation in melanoma sp
OBJECTIVES: Assessment of inflammatory activity in interstitial lung disease of systemic sclerosis (SSc) is difficult. Nitric oxide (NO) has gained attention in the pathogenesis of SSc. The aim of the study was to investigate alveolar NO concentration (CA(NO)) in SSc patients with short disease duration and to relate CA(NO) to radiologic findings. METHODS: In a prospective study, 34 consecutive pa
Background. The recommended treatment for chronic musculoskeletal pain is multidisciplinary, with a cognitive approach. The aim of this study was to investigate health-related quality of life (HRQoL) outcome after a multidisciplinary treatment with a cognitive approach. Methods. A total of 131 subjects who participated in a multidisciplinary rehabilitation programme (2005-2008) were studied at bas
Lung cancer is the worldwide leading cause of death from cancer and has been shown to be a heterogeneous disease at the genomic level. To delineate the genomic landscape of copy number alterations, amplifications, loss-of-heterozygosity (LOH), tumor ploidy and copy-neutral allelic imbalance in lung cancer, microarray-based genomic profiles from 2,141 tumors and cell lines including adenocarcinomas
OBJECTIVE: Gene expression alterations, especially in target tissues of insulin, have been associated with type 2 diabetes (T2D). Here, we examined if genes involved in oxidative phosphorylation (OXPHOS) show differential gene expression and DNA methylation in pancreatic islets from patients with T2D compared with non-diabetic donors. DESIGN AND METHODS: Gene expression was analyzed in human panc
BACKGROUND: Atrial septal pacing (ASP) has been shown to shorten P-wave duration (PWD) and reduce recurrence of atrial fibrillation (AF) in patients with bradyarrhythmias. However, variability of interatrial connections and atrial conduction properties may explain ASP's modest clinical benefit. The aim of this study was to assess the effect of ASP site on the duration of the paced P wave. METHODS
Background/Objectives:Dietary addition of either conjugated linoleic acid (CLA) or n-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFAs) has been shown to alter adiposity and circulating lipids, risk markers of cardiovascular diseases. However, CLA may decrease insulin sensitivity, an effect that may be reversed by n-3 LC-PUFA. Thus, the potential of CLA plus n-3 LC-PUFA to affect insulin secr
Background Family history is a strong risk factor for prostate cancer. The aim of this study was to investigate whether increased diagnostic activity is related to the incidence of prostate cancer among brothers of men with prostate cancer. Methods Data were from the nationwide population-based Prostate Cancer Database Sweden (PCBaSe Sweden), which includes data from the National Prostate Cancer R
We report on precise Doppler measurements of L231-32 (TOI-270), a nearby M dwarf (d = 22 pc, M = 0.39 M, R = 0.38 R), which hosts three transiting planets that were recently discovered using data from the Transiting Exoplanet Survey Satellite (TESS). The three planets are 1.2, 2.4, and 2.1 times the size of Earth and have orbital periods of 3.4, 5.7, and 11.4 d. We obtained 29 high-resolution opti
Knowledge of how biodiversity sustains ecosystem function comes predominantly from studies focused on small spatial scales. Thus, we know relatively little about the role of biodiversity at larger scales of space and time where habitats become increasingly heterogeneous. Efforts to upscale the relationship between biodiversity and function have yielded inconclusive results. Given that increasing h
