Recent magnetic-resonance work on Y-Z suggests that this species exhibits considerable motional flexibility in its functional site and that its phenol oxygen is not involved in a well-ordered hydrogen-bond interaction (Tang et al., submitted; Tommos et al., in press). Both of these observations are inconsistent with a simple electron-transfer function for this radical in photosynthetic water oxida
Effects of A-322312 (alpha(1B)-adrenoceptor (AR) antagonist), A-119637 (alpha(1D)-AR antagonist), prazosin (non-selective alpha(1)-AR antagonist), and yohimbine (alpha(2)-AR antagonist) were studied in rat corpus cavernosum (CC) and cavernous artery (Acc) preparations. Effects of intracavernous (i.c.) or intraperitoneal (i.p.) administration of alpha(1)-AR antagonists on apomorphine-induced erecti
Objective: Rate of non-attendance following invitation for breast cancer screening is related to several socioeconomic conditions. To what extent this reflects differences with regard to individual and environmental circumstances, respectively, has received little attention. The purpose of this study was to investigate the effect of individual socioeconomic and area-level determinants on variation
The stage-specific embryonic antigen 4 (SSEA4) is commonly used as a cell surface marker to identify the pluripotent human embryonic stem (ES) cells. Immunohistochemistry on human embryonic central nervous system revealed that SSEA4 is detectable in the early neuroepithelium, and its expression decreases as development proceeds. Flow cytometry analysis of forebrain-derived cells demonstrated that
A simplistic approach to optimising medical imaging is to use the lowest effective dose to the patient that does not jeopardise a correct diagnosis. With limited resources and over 1000 different types of X-ray examinations, it is not always easy to set the right priorities and to decide how to perform the optimisation. Recent research shows that the 'Rose model' for the detection of specific stru
Epidemiological studies have indicated a relationship between overweight and cardiovascular disease. The present investigation was undertaken to identify anthropometric variables in childhood which may reflect the risk of cardiovascular disease in terms of unfavourable changes in apolipoprotein and lipid concentrations. Twenty-nine obese 14-year-olds and 32 obese 12-year-olds were recruited from a
Popular Abstract in Swedish Syftet med avhandlingen är att presentera en sociologisk analys av en "religionsfrihetssituation". Den grupp som särskilt berörs i avhandlingen är den invandrarde muslimska minoriteten i Sverige, en grupp som har vuxit avsevärt under de senaste decennierna. Muslimerna har invandrat till ett samhälle som länge präglades av religiös enhet, men som idag har utvecklats tillThis dissertation deals with the religious liberty situation of the Muslim minority in Sweden. The Muslim minority has grown considerably in recent decades as a consequence of labour and refugee immigration of a large scale, which has caused a change in Swedish society from an etnically, culturally and religously homogeneous situation to one of a significant heterogeneity. Sweden's way from unity
Student speech production is an essential part of language learning in the foreign-language classroom. The students usually have few opportunities to use the language outside the classroom, which underscores the importance of making good use of the time spent in the classroom. Much research has shown that learner output is necessary, or at least facilitative, in language acquisition. This claim fo
We investigated the excited-state dynamics of CH3NH3PbBr3 perovskite nanoparticles (NPs) and bulk crystals under various excitation intensity regimes using transient absorption spectroscopy. We confirmed the sub-band gap hole trap states with optical transition to the conduction band in both samples. In bulk crystals, the excited-state dynamics is independent of pump intensity. However, in NPs, pr
The rate of removal of phosphatidylethanolamine and phosphatidylcholine from the plasma of rats treated with antiserum to hepatic lipase was measured. The hepatic lipase antiserum was injected intravenously into animals prior to injection of 32P-labeled chylomicrons or 32P-labeled high density lipoproteins. In experiments in which 32P-labeled chylomicrons were injected, antiserum treatment inhibit
OBJECTIVES: An extended-wavelength diffuse reflectance spectroscopy (EWDRS) technique was evaluated for its ability to differentiate between and classify different skin and tissue types in an in vivo pig model.MATERIALS AND METHODS: EWDRS recordings (450-1550 nm) were made on skin with different degrees of pigmentation as well as on the pig snout and tongue. The recordings were used to train a sup
Total scattering and pair distribution function (PDF) analysis has created new insights that traditional powder diffraction methods have been unable to achieve in understanding the local structures of materials exhibiting disorder or complex nanostructures. Care must be taken in such analyses as subtle and discrete features in the PDF can easily be artefacts generated in the measurement process, w
The dichotomous roles client/ social worker is often portayed as the client having problems, and the social worker knowing the solutions. Reciprocity is limited in traditional social work practice in Sweden. The organizational framing seldom offer good potentials for common ground, inclusion or co-production.Since 2005 the traditional roles in social work practice have been challenged in an experi
The visual world projects a complex and rapidly changing image onto the retina of many animal species. This presents computational challenges for those animals reliant on visual processing to provide an accurate representation of the world. One such challenge is parsing a visual scene for the most salient targets, such as the selection of prey amid a swarm. The ability to selectively prioritize pr
