- Precarious manhood beliefs portray manhood, relative to womanhood, as a social status that is hard to earn, easy to lose, and proven via public action. Here, we present cross-cultural data on a brief measure of precarious manhood beliefs (the Precarious Manhood Beliefs scale [PMB]) that covaries meaningfully with other cross-culturally validated gender ideologies and with country-level indices of gender equality and human development. Using data from university samples in 62 countries across 13 world regions (N = 33,417), we demonstrate: (1) the psychometric isomorphism of the PMB (i.e., its comparability in meaning and statistical properties across the individual and country levels); (2) the PMB's distinctness from, and associations with, ambivalent sexism and ambivalence toward men; and (3) associations of the PMB with nation-level gender equality and human development. Findings are discussed in terms of their statistical and theoretical implications for understanding widely-held beliefs about the precariousness of the male gender role.

- Atrial fibrillation (AF) practice guidelines recommend a rhythm-control strategy to improve symptoms and quality of life, noting the side effects of antiarrhythmic drugs and catheter ablation. Emerging evidence indicates that comprehensive early rhythm control with antiarrhythmic drugs or catheter ablation is associated with a lower risk of adverse cardiovascular outcomes versus the usual care. Using an online modified Delphi survey approach, perspectives and expert consensus among electrophysiologists were examined through a series of ranking and likelihood questions around treatment decision-making on (1) the use of comprehensive early rhythm-control strategies in patients with AF based on guidelines and emerging research and (2) treatment selection factors. A panel of 17 electrophysiologists reached a consensus on using early rhythm control (median 90, interquartile range 14) based on the view that early intervention improved cardiovascular outcomes (mean rank 1.6 of 3, 82% within 1 SD) and symptoms (1.8 of 3, 41%). AF-related symptoms were identified as the most important in making a treat-ment initiation decision (1.1 of 7, 88%), followed by AF type (2.5 of 7, 82%). Participants were most likely to initiate treatment at AF symptom onset (median 80; interquartile range 6). In making treatment selection decisions, participants ranked short-term/long-term safety (1.9 of 7, 88%) and efficacy (1.8 of 7, 53%) as the top 2 considerations. In conclusion, experts were in favor of early rhythm control; however, additional research is needed to address the role that early rhythm-control strategies play in current AF treatment management algorithms.

Point-contact spectroscopy in heavy-fermion superconductors
- 2010

- We develop a microscopic model to calculate point-contact spectra between a metallic tip and a superconducting heavy-fermion system. We apply our tunneling model to the heavy fermion CeCoIn5, both in the normal and superconducting states. In point contact and scanning tunneling spectroscopy many heavy-fermion materials, such as CeCoIn5, exhibit an asymmetric differential conductance, dI/dV, combined with a strongly suppressed Andreev reflection signal in the superconducting state. We argue that both features may be explained in terms of a multichannel tunneling model in the presence of localized states near the interface. We find that it is not sufficient to tunnel into two itinerant bands of light and heavy electrons to explain the Fano line shape of the differential conductance. Localized states in the bulk or near the interface are an essential component for quantum interference to occur when an electron tunnels from the metallic tip of the point contact into the heavy-fermion system.

Physiological and structural anorectal abnormalities in patients with systemic sclerosis and fecal incontinence

- ObjectiveFecal incontinence is common in systemic sclerosis (SSc), but the underlying mechanisms are not fully understood. The objectives of this study were to characterize anorectal physiological and morphological defects in SSc patients and to correlate the results with incontinence symptoms.Materials and methodsTwenty-five SSc patients underwent anorectal neurophysiological investigations, anal manometry, and ultrasound.ResultsEleven patients (44%) reported incontinence to solid or liquid feces, but no patient reported diarrhea. Increased fiber density (FD) was recorded in 78% of patients with and in 86% of patients without fecal incontinence not significant (NS). Incontinent patients had lower squeeze pressure (SP; median 49.5 mm Hg) in the high-pressure zone (HPZ) than continent patients (median 72 mm Hg; p = 0.01). In two of the incontinent patients, sonographic abnormalities of the internal anal sphincter (IAS) and the external anal sphincter (EAS) were present, whereas in another two patients isolated IAS abnormalities were seen. These four individuals had lower resting pressure at 1 cm and in the HPZ, and lower SP at 2 cm than patients with normal anorectal sonographic findings (p < 0.05).ConclusionLower voluntary SP in incontinent patients and EAS sonographic abnormalities only in patients with incontinence suggest that the EAS is more important in maintaining fecal continence in SSc patients than has previously been reported. The finding of increased FD in most patients further supports involvement of the EAS function in SSc and could indicate previous nerve injury with consequent incomplete reinnervation.

Femtosecond X-ray diffraction from two-dimensional protein crystals
- 2014

Tidskriftsartikel (refereegranskat)abstract
- X-ray diffraction patterns from two-dimensional (2-D) protein crystals obtained using femtosecond X-ray pulses from an X-ray free-electron laser (XFEL) are presented. To date, it has not been possible to acquire transmission X-ray diffraction patterns from individual 2-D protein crystals due to radiation damage. However, the intense and ultrafast pulses generated by an XFEL permit a new method of collecting diffraction data before the sample is destroyed. Utilizing a diffract-before-destroy approach at the Linac Coherent Light Source, Bragg diffraction was acquired to better than 8.5 Å resolution for two different 2-D protein crystal samples each less than 10 nm thick and maintained at room temperature. These proof-of-principle results show promise for structural analysis of both soluble and membrane proteins arranged as 2-D crystals without requiring cryogenic conditions or the formation of three-dimensional crystals.

- Research infrastructures play a key role in launching a new generation of integrated long-term, geographically distributed observation programmes designed to monitor climate change, better understand its impacts on global ecosystems, and evaluate possible mitigation and adaptation strategies. The pan-European Integrated Carbon Observation System combines carbon and greenhouse gas (GHG; CO2, CH4, N2O, H2O) observations within the atmosphere, terrestrial ecosystems and oceans. High-precision measurements are obtained using standardised methodologies, are centrally processed and openly available in a traceable and verifiable fashion in combination with detailed metadata. The Integrated Carbon Observation System ecosystem station network aims to sample climate and land-cover variability across Europe. In addition to GHG flux measurements, a large set of complementary data (including management practices, vegetation and soil characteristics) is collected to support the interpretation, spatial upscaling and modelling of observed ecosystem carbon and GHG dynamics. The applied sampling design was developed and formulated in protocols by the scientific community, representing a trade-off between an ideal dataset and practical feasibility. The use of open-access, high-quality and multi-level data products by different user communities is crucial for the Integrated Carbon Observation System in order to achieve its scientific potential and societal value.

- OBJECTIVE: To evaluate the results after Delorme's operation for rectal prolapse in elderly and unfit patients.DESIGN: Retrospective analysis and telephone interview.SETTING: Akademiska sjukhuset, Uppsala, Sweden.SUBJECTS: A consecutive series of 14 women (median age 82, range 32-92) operated on for rectal prolapse 1987-1992 and followed up after a median of 18 months.RESULTS: There were no serious postoperative complications. Continence was improved in 6/11 incontinent patients. The recurrence rate was 3/14 (21%).CONCLUSION: Delorme's operation is an attractive alternative in elderly or unfit patients, but is not recommended for younger and low risk patients because of the recurrence rate.
