Cluster analysis of 100 Marfan patients based on aortic 4D flow MRI and Z-score: insights into disease heterogeneity and stratification of subgroups.

Objectives: 4D flow MRI-derived variables from Marfan patients are highly heterogeneous. Our aim was to identify distinct Marfan patient subgroups based on aortic 4D flow MRI and Z-score for stratification of distinct hemodynamic profiles and clinical features by means of hierarchical cluster analysis.

Materials And Methods: One hundred Marfan patients underwent baseline aortic 4D flow MRI at 3 T.

Tocilizumab for the Treatment of Familial Mediterranean Fever-A Randomized, Double-Blind, Placebo-Controlled Phase II Study.

Background: The purpose of this trial was to evaluate the effectiveness and safety of the IL-6 receptor antibody Tocilizumab (TCZ) in the treatment of Familial Mediterranean Fever (FMF). Methods: This was a randomized, double-blinded, placebo-controlled phase II trial in adult patients with active FMF and an inadequate response or intolerance to colchicine (crFMF). The physician’s global assessment of disease activity (PGA), based on a five-point scale for six symptoms, was used as a clinical score, which had to be >2 at screening, together with elevated c-reactive protein (CRP) or erythrocyte sedimentation rate (ESR) and serum amyloid A (SAA) levels, to be eligible for inclusion.

Examining marginalized communities and local conservation institutions: the case of Nepal's Annapurna Conservation Area.

In developing countries, participatory conservation initiatives have been criticized for many reasons, mainly for excluding marginalized groups which have led to unequal benefits. Using concepts from the literature on participation, conservation, and political ecology, this research explored the participation of marginal groups, i.e.

Examining the role of voluntary associations in environmental management: the case of the Sam Houston national forest.

The purpose of this study was to gain a better understanding of voluntary associations involved in forest management. The specific areas examined in this study include organizational attributes, membership profile, attitudes toward forest-management priorities, and concerns about forest-management issues. To achieve this purpose, data were collected using a case study approach with mixed-methods (document reviews, personal interviews, and a Web survey) at a national forest in Texas, USA.

Chromosomal instability determines taxane response.

Microtubule-stabilizing (MTS) agents, such as taxanes, are important chemotherapeutics with a poorly understood mechanism of action. We identified a set of genes repressed in multiple cell lines in response to MTS agents and observed that these genes are overexpressed in tumors exhibiting chromosomal instability (CIN). Silencing 22/50 of these genes, many of which are involved in DNA repair, caused cancer cell death, suggesting that these genes are involved in the survival of aneuploid cells.
