Liquid phase time-resolved x-ray diffraction with 100 ps resolution has recently emerged as a powerful technique for probing the structural dynamics of transient photochemical species in solution. It is intrinsic to the method, however, that a structural signal is observed not only from the photochemical of interest but also from the embedding solvent matrix. To experimentally characterize the x-r
In bright light the photosynthetic reaction center (RC) of Rhodobacter sphaeroides stabilizes the P(+)(870).Q(-)(A) charge-separated state and thereby minimizes the potentially harmful effects of light saturation. Using X-ray diffraction we report a conformational change that occurs within the cytoplasmic domain of this RC in response to prolonged illumination with bright light. Our observations s
Proton pumping nicotinamide nucleotide transhydrogenase from Escherichia coli contains an alpha subunit with the NAD(H)-binding domain I and a beta subunit with the NADP(H)-binding domain III. The membrane domain (domain II) harbors the proton channel and is made up of the hydrophobic parts of the alpha and beta subunits. The interface in domain II between the alpha and the beta subunits has previ
BACKGROUND AND OBJECTIVES: ABO-incompatible haematopoietic stem cell transplantation (HSCT) presents a challenge to blood component transfusion. The aim of this study was to investigate the weak blood group A or B antigen expression by donor-derived group O red blood cells (RBC) observed following transfusion or minor ABO-incompatible HSCT. In addition, in vitro experiments were performed to eluci
Urinary tract infections (UTIs) are among the most common infectious diseases in humans, with a subset of susceptible individuals who experience recurrent episodes. The increase in antibiotic resistance in gram-negative uropathogens, due to antibiotic overuse, is a strong rationale for developing therapeutic alternatives and to improve diagnostics.

AIM: The aim of this study was to follow the symptom trajectory of community-dwelling older people with multimorbidity and to explore the effect on symptom burden from an ambulatory geriatric care unit, based on comprehensive geriatric assessment.BACKGROUND: Older community-dwelling people with multimorbidity suffer from a high symptom burden with a wide range of co-occurring symptoms often result
OBJECTIVE: To compare the effects of care based on comprehensive geriatric assessment (CGA) as a complement to usual care in an outpatient setting with those of usual care alone. The assessment was performed 36 months after study inclusion.DESIGN: Randomized, controlled, assessor-blinded, single-center trial.SETTING: A geriatric ambulatory unit in a municipality in the southeast of Sweden.PARTICIP
Previous findings suggest a link between neuroinflammatory processes and suicidality. Despite several lines of evidence supporting this link, including increased pro-inflammatory markers in blood-, cerebrospinal fluid (CSF)- and in post-mortem brain samples from suicidal individuals, the underlying mechanisms remain poorly understood. In this pilot study, we explored the possibility that autoimmun
Treatment resistant depression (TRD) and suicidal behavior are among the most important public health problems and are commonly associated with significant disability and psychosocial impairment. Although there have been recent advances in identifying neurobiological correlates of these complex conditions, their pathophysiology still remains unclear. Although the recent advances concerning the neu
Ensuring sustainable consumption and production is one of the United Nations’ Sustainable Development Goals. Sustainable consumption can be supported through regulatory processes. Voluntary private regulatory schemes claiming to contribute to sustainability are a rapidly growing form of regulation. We study one such voluntary sustainability scheme in order to look at the opportunities and challeng
Everyday international political economy (EIPE) offers an opportunity to rethink the role of individuals and citizenry in shaping governance of natural resources. In South Africa, significant progress has been made by government in re-shaping water governance since the end of apartheid in the early 1990s. The role of government in water governance and water politics has thus been emphasised to a l
The past few decades have seen an increasing demand for environmental information on which to make more informed decisions, strengthened by several international calls for improving available environmental information. In a democratic South Africa, the involvement of people in policy and decision-making processes has led to an even greater need for accessible information. In response to this deman
