Sexual selection against immigrants is a mechanism that can regulate premating isolation between populations but, so far, few field studies have examined whether males can discriminate between immigrant and resident females. Males of the damselfly Calopteryx splendens show mate preferences and are able to force pre-copulatory tandems. We related male mate responses to the ecological characteristic
Objectives: To estimate intra- and inter-observer reproducibility and reliability of assessment of the color content in adnexal masses at color/power Doppler ultrasound examination for observers with different levels of experience, and to determine if they change after a consensus meeting. Methods: Digital clips with color/power Doppler information of 103 adnexal masses were evaluated independentl
Physical, chemical and biological variables were quantified in 19 subantarctic lakes (South Georgia) as a prelude to comparing these pristine systems with temperate lakes and to improve the knowledge of spatial and temporal variation in water chemistry and abundances of organisms. Lakes close to the sea had higher phosphorus concentrations, contained higher abundances of most organisms, and had hi
Molecular oxygen has been detected in the coma of comet 67P/Churyumov-Gerasimenko with a mean abundance of 3.80 ±0.85% by the ROSINA mass spectrometer on board the Rosetta spacecraft. To account for the presence of this species in comet 67P/Churyumov-Gerasimenko, it has been shown that the radiolysis of ice grain precursors of comets is a viable mechanism in low-density environments, such as molec
1. In the rat hepatic artery, the acetylcholine-induced relaxation mediated by endothelium-derived hyperpolarizing factor (EDHF) is abolished by a combination of apamin and charybdotoxin, inhibitors of small (SK(Ca)) and large (BK(Ca)) conductance calcium-sensitive potassium (K)-channels, respectively, but not by each toxin alone. The selective BK(Ca) inhibitor iberiotoxin cannot replace charybdot
Background Trauma audit filters, based on standards of care, serve as quality indicators and screening tools for patient cases to be assessed at interdisciplinary morbidity and mortality conferences. These conferences aim to identify potential opportunities for improvement in the care of trauma patients. This study aimed to determine the performance of individual audit filters in predicting opport
This paper will discuss the memory-political narrative of the Tower of David Museum, located in the Old City of Jerusalem/al Quds. As part of a current research project on the role of urban imageries and spaces in constructions of Middle Eastern nationalisms, it will explore how the museum is part and parcel of the interwoven historiographic, cultural, and political quest to normalise and obscure
Assuming that the wave function of the [Formula Presented] ground state of [Formula Presented]Ra is quadrupole-octupole deformed with [Formula Presented] [Formula Presented] [Formula Presented] [Formula Presented], and [Formula Presented] having the optimum values of 0.129, 0.075, 0.004, 0.10, and 0.01, respectively, its amplitude in the wave functions of the [Formula Presented] [Formula Presented
Obstructive sleep apnea (OSA) has been hypothesised to promote cancer via intermittent hypoxia, and assessing what happens when OSA is controlled by continuous positive airway pressure (CPAP) may provide valuable insight. We conducted a meta-analysis of three randomised controlled trials (SAVE, RICCADSA, ISAACC) assessing cancer incidence from adverse event data on neoplasms among OSA patients ran
Background: Azithromycin (AZM) effectively reduces asthma exacerbations and enhances bronchial epithelial cell (BEC) antiviral immunity in vitro. However, its clinical impact on different asthma phenotypes is not fully elucidated and differences in treatment response to AZM may be attributable to differences in immune activation to rhinovirus (RV) infection in different inflammatory asthma phenoty
Breviates are anaerobic protists and among the closest unicellular relatives of animals and fungi, yet their ecology and metabolism remain poorly understood. In this thesis, I investigated the distribution, metabolic potential, and bacterial interactions of breviates in low-oxygen environments. Breviates rely on bacteria both as a food source and potentially as metabolic partners. Breviates are pr
Objective: To investigate whether low daily doses of fluoridated milk, as an adjunct to oral hygiene routines with fluoridated toothpaste, can prevent caries development in enamel and dentine in adolescents. Material and methods: Adolescents (mean age 13 years) at three dental clinics in Sweden were enrolled to a randomised clinical trial (RCT) including baseline and 2-year follow-up examinations.
Background: Agroecology integrates ecological agricultural production with community self-reliance, deeply rooted in indigenous knowledge. This study investigates how and why women in Zimbabwe contribute to seed preservation in agroecology, and what challenges they face in sustaining traditional seed systems. Using a qualitative approach combining focus group discussions, semi-structured interview
