Research in community ecology has tended to focus on trophic interactions (e.g., predation, resource competition) as driving forces of community dynamics, and sexual interactions have often been overlooked. Here we discuss how sexual interactions can affect community dynamics, especially focusing on frequency-dependent dynamics of horizontal communities (i.e., communities of competing species in a
Long-read sequencing offers a great improvement in the assembly of complex genomic regions, such as the major histocompatibility complex (MHC) region, which can contain both tandemly duplicated MHC genes (paralogs) and high repeat content. The MHC genes have expanded in passerine birds, resulting in numerous MHC paralogs, with relatively high sequence similarity, making the assembly of the MHC reg
Purpose: An increasing number of children and young adults with complex medical conditions and respiratory failure are treated with home mechanical ventilation (HMV). The current study aimed to describe how young adults using HMV experience their everyday life with the ventilator, their physical impairments and their opportunities for an educational and professional career. Materials and methods:
Chemical processing by plasma is utilized in many applications. Plasma-related studies, however, are challenging to carry out due to plasmas' transient and unpredictable behavior, excessive luminosity emission, 3D complexity and aggressive chemistry and physiochemical interactions that are easily affected by external probing. Laser-induced fluorescence is a robust technique for non-intrusive inves
Recurrent pregnancy loss (RPL), defined as three or more consecutive miscarriages, is hypothesized to share some of the same pathogenic factors as placenta-associated disorders. It has been hypothesized that a defect implantation causes pregnancy loss, while a partially impaired implantation may lead to late pregnancy complications. The aim of this retrospective register-based cohort study was to
BACKGROUND: Accumulating evidence suggests a relationship between endometrial cancer and ovarian cancer. Independent genome-wide association studies (GWAS) for endometrial cancer and ovarian cancer have identified 16 and 27 risk regions, respectively, four of which overlap between the two cancers. We aimed to identify joint endometrial and ovarian cancer risk loci by performing a meta-analysis of
Introduction: Patients with midgut neuroendocrine tumours (NETs) suffer from decreased health-related quality of life (HRQoL), in large part due to bowel symptoms. However, it is unknown which bowel symptoms affect HRQoL the most. An enhanced understanding of this is essential to better focus treatment on this aspect of the disease. This study aimed to determine which bowel symptoms affect HRQoL t
Objective: To compare the rate of vaginal birth after cesarean section (VBAC), including the maternal and perinatal outcomes, in two historical cohorts before and after the implementation of specific changes in the clinical practice. Design: A retrospective cohort study. Setting: Skåne University Hospital in Malmö, Sweden. Participants: including all women with one previous cesarean section (CS),
Background: In clinic, a subjective visual estimation of a patient’s general health often guides interventions, yet little is known of how this assessment relates to objectively measured frailty. Aims: To characterize the relationship between these two assessments and explore the implication of discordance. Methods: The study was performed in the OPRA cohort of 75-year old community-dwelling women
Persons with stress-related disorders, mental disorders and neuropsychiatric disabilities are in particular vulnerable to cognitive challenges at the workplace. The barriers faced by persons with communicative, social and cognitive disabilities are most often invisible to persons in the environment. The objective of the study presented in this paper is to develop and test a tool that increases awa
Background: Pain from various locations in the body and mental illness are common and the comorbidity between the two is well-known although the temporal relationship remains to be determined. Our aim was to follow patients over time to study if pain (here dorsalgia/abdominal pain) or fibromyalgia lead to an increased risk of developing mental illness (here depression/anxiety) and/or the reverse,
We study the spectral phase introduced by parametric amplification and how high extraction efficiency of energy leads to deterioration of the phase. Avoiding this regime, and using a pulse shaper, we achieve high-contrast ultrashort pulses.
We report ultraviolet-induced transient and stable absorption and two-color holographic recording at 514, 633, and 830 nm in thulium doped stoichiometric LiNbO 3 crystal. The gating light at 355 nm increased the diffraction efficiency and sensitivity. We found the optimum gating-recording intensity ratio for maximum diffraction efficiency and weak nonvolatile holographic storage with gating.
The reduction of public expenditure and investments in health care provisioning calls for new, sustainable models to transform the increasing aging population and dementia-related diseases incidence from global challenges into new opportunities. In this context, Information and Communication Technologies play a vital role, to both promote aging in place and home management of Patients with Dementi
The current war in Ukraine has severely disrupted global food supply chains due to the significant decline in the production of grain commodities, of which Ukraine and Russia are major global suppliers. This creates problems in today’s globalised food systems. In particular, a number of countries are heavily dependent on food imports from Ukraine and/or Russia, particularly some developing nations
