Virtual magnetic resonance elastography (vMRE) is an experimental imaging modality designed to non-invasively predict the haptic properties of tissues. The modality is sensitive to tissue stiffness and fibrosis. Information about meningioma consistency prior to resection is of great interest in neurological surgery as the surgical plan and outcome may be affected by the tumor's stiffness. In this study, we assessed the ability of vMRE to predict the intraoperative consistency and mechanical heterogeneity of intracranial meningiomas.

Background: Patients with chronic inflammatory diseases (CIDs) may encounter challenges in their family planning journey. Here, we report on the access to family planning and pregnancy (FPP) information and the concerns among patients in Denmark with CIDs. Methods: Patients aged 18–50 years with CIDs participated in an online survey. Patients were recruited through patient advocacy groups and were asked to report information on their diagnosis, concerns related to FPP and perceptions of access to FPP information. Descriptive statistics were applied. Results: Of the eligible respondents, 368 had rheumatological diagnoses (rheumatoid arthritis, psoriatic arthritis, juvenile idiopathic arthritis or axial spondyloarthritis; mean age 40 years; 83% women, 17% men) and 95 had dermatological diagnoses (psoriasis or psoriatic arthritis; mean age 38 years; 67% women, 33% men). Approximately 70% of all patients reported seeking FPP information from patient advocacy groups; 57% of both cohorts used the internet as information sources; and 73% and 42% of rheumatological and dermatological cohorts used their hospital and specialist doctor, respectively. Despite this, 58% and 67% of patients with rheumatological and dermatological diagnoses reported limited or no access to FPP information, with > 70% of dermatological patients of early/mid-reproductive age reporting a lack of access to this information. Overall, 68% of patients with rheumatological and 73% with dermatological diagnoses had biological children, amongst whom 24% and 18%, respectively, indicated their disease affected the number of children they ultimately decided to have. The most frequent FPP concerns among patients who did not want any/more biological children were disease worsening, heredity and taking care of the child. Conclusions: Despite awareness of available sources of FPP information, patients expressed experiencing a feeling of limited access to information and having concerns that affect key decisions regarding FPP. The results of this survey highlight a need for improved and more standardised FPP information for patients with CIDs in Denmark.

•Survey revealed low awareness of teratogenic risk during disease modifying therapy.•Knowledge of potential exposure to healthy partners of male patients was absent.•10% of female multiple sclerosis patients had experienced unplanned pregnancies.•The internet and the neurologist were key sources of information on family planning.

Recent studies have characterized the ABC half-transporter associated with mitoxantrone resistance in human cancer cell lines. Encoded by the ABCG2 gene, overexpression confers resistance to camptothecins, as well as to mitoxantrone. We developed four polyclonal antibodies against peptides corresponding to four different epitopes on the mitoxantrone resistance-associated protein, ABCG2. Three epitopes localized on the cytoplasmic region of ABCG2 gave rise to high-affinity antibodies, which were demonstrated to be specific for ABCG2. Western blot analysis of cells with high levels of ABCG2 showed a single major band of the expected 72-kDa molecular size of ABCG2 under denaturing conditions. Immunoblot analysis performed under non-reducing conditions and after treatment with cross-linking reagents demonstrated a molecular weight shift from 72 kDa to several bands of 180 kDa and higher molecular weight, suggesting detection of dimerization products of ABCG2. Evidence of N -linked glycosylation was also obtained using tunicamycin and N -glycosidase F. Finally, both by light, fluorescence and electron microscopic immunohistochemical staining, we demonstrate cytoplasmic and predominantly plasma membrane localization of ABCG2 in cell lines with high levels of expression. Plasma membrane staining was observed on the surface of the chorionic villi in placenta. These results support the hypothesis that ABCG2 is an ABC half-transporter that forms dimers in the plasma membrane, functioning as an ATP-dependent outward pump for substrate transport.

Plating of individual soil particles onto an agar medium, poured into Petri dishes, is a method of studying fungal distribution between microhabitats in soil. The substitution of Petri dishes with well plates reduced both the required amount of agar medium and labour. A microshovel prepared from an injection needle facilitated the handling of individual, small size, soil particles (0·25–0·50 mm). The described method was evaluated in a study of the distribution of Fusarium within two wheat field soils from Ås, Norway, and from Østermarie, Denmark. Four types of organic particles were distinguished: light coloured root pieces, dark coloured root pieces, straw pieces, and miscellaneous organic pieces. The dominating species were F. culmorum, F. oxysporum and F. avenaceum. Aspects on the value of the method with regard to fungal substrate preference are discussed.
