Divergence in sexually selected traits in allopatry should affect the degree and direction of hybridization. However, few studies have established the causes and targets of sexual selection during secondary contact. Common wall lizards (Podarcis muralis) from north-central Italy have highly exaggerated male sexual traits compared to populations in Western Europe. Using experimental populations, we

In recent years many studies into green solvents have been undertaken and deep eutectic solvents (DES) have emerged as sustainable and green alternatives to conventional solvents since they may be formed from cheap non-toxic organic precursors. In this study we examine amphiphile behaviour in these novel media to test our understanding of amphiphile self-assembly within environments that have an i

Ethnic minorities have particular needs and difficulties in terms of support for meaningful occupations, lack of access to and use of occupation-based rehabilitation services. They are not established in the labour market and are seldom in paid employment. This study aimed to investigate how mentally ill ethnic minority clients experience, feel and think about participation in occupation-based reh

Background: Day centres can prepare for open-market employment, and attendees’ work motivation is key in this. Aims: Adopting a gender perspective, this study investigated (1) motivation for day centre attendance, satisfaction with the day centre services, number of hours spent there, and number and type of occupations performed; and (2) whether those factors were related with motivation for open-

Several earlier studies have shown improvement of glaucomatous visual fields after pressure reduction achieved by acetazolamide or filtering surgery, while other studies have given conflicting results. In the present study laser trabeculoplasty was used to reduce the IOP in 42 eyes with glaucomatous visual field defects. Although good pressure reduction was achieved, no general regression of field

OBJECTIVE: To study prospectively the effects of perimetric learning in glaucoma patients.PATIENTS AND METHODS: Twenty-five patients with newly detected glaucoma underwent repeated perimetric testing using the 30-2 full threshold program with the Humphrey perimeter. Each patient was tested five times at about 1-week intervals. No patient had undergone perimetry before entering the study.RESULTS: I

The aim of this study was to ascertain how many of the sporadic cases of severe Haemophilia A in Sweden are due to recent mutation, and establish its origin. DNA analysis was performed in 18 randomly selected families with a sporadic case of severe haemophilia A. Restriction fragment length polymorphism (RFLP) patterns were investigated, two intragenic (Bc1 I, Xba I/Kpn I) and two extragenic (DX 1

In the dense and crowded environment of the cell cytoplasm, an individual protein feels the presence of and interacts with all surrounding proteins. While we expect this to strongly influence the short-time diffusion coefficient Ds of proteins on length scales comparable to the nearest-neighbor distance, this quantity is difficult to assess experimentally. We demonstrate that quantitative informat

In pristine Sphagnum-dominated peatlands, (di)nitrogen (N2) fixing (diazotrophic) microbial communities associated with Sphagnum mosses contribute substantially to the total nitrogen input, increasing carbon sequestration. The rates of symbiotic nitrogen fixation reported for Sphagnum peatlands, are, however, highly variable, and experimental work on regulating factors that can mechanistically exp

The feasibility of applying friction stir processing (FSP) to locally homogenise and to refine the microstructure of a recently developed Mg-Zn-Ca(-Zr) alloy, ZKX50, has been examined. The application of a single pass of FSP resulted in dissolution of coarse intermetallic particles at dendrite boundaries and grain refinement, from an average grain size of ~60 µm in the as-cast state to ~1.2 µm. Th

Phthalates and phenolic substances were investigated in urine samples from first-time mothers in Uppsala, Sweden, collected between 2009 and 2014. These substances have a comparably fast metabolism and urinary metabolites are predominantly analysed. The main aim was to investigate if measures to decrease production and use of certain phthalates and bisphenol A (BPA) have resulted in decreased huma

Adenosine is a neuromodulator that protects neurons from hypoxia. This effect is attributed to the ability of adenosine A1 receptors (A1 R) to inhibit excitatory synaptic transmission. However, A1 R activation also protects non-brain tissues from hypoxic insults by controlling metabolism. Thus, we now tested the hypothesis that A1 R-mediated neuroprotection after a hypoxic insult in superfused hip

Energy-resolved electron-ion coincidence spectra of the deuteromethane molecule were measured following ionization by narrow-band synchrotron radiation. The ion mass spectra were recorded in coincidence with the outer and inner valence photoelectrons and with the normal Auger electrons from the decay of the carbon 1s core hole. Complementary noncoincidence ion mass spectra were measured below and

Popular Abstract in Swedish Dysfagi är ett symptom på onormal sväljningsförmåga. Detta symptom kan förekomma i samband med många olika sjukdomstillstånd men är vanligast i samband med olika neurologiska sjukdomar t ex stroke. Symptomen kan variera från en lätt känsla av upphakning och svårigheter att svälja specifik föda till livshotande kvävningsanfall. Logopeder har de senaste decennierna tagit In this study simultaneous videoradiography and intraluminal manometry (videomanometry) have been used in combination in three studies to analyze how different therapeutic strategies affect the physiology of swallowing in healthy volunteers and in patients with pharyngeal dysfunction. Analyses of healthy volunteers showed few significant measurable effects on the pharyngeal swallow. Some decreased
