We performed transient absorption (TA) measurements on CP29 minor light-harvesting complexes that were reconstituted in vitro with either violaxanthin (Vio) or zeaxanthin (Zea) and demonstrate that the Zea-bound CP29 complexes exhibit charge-transfer (CT) quenching that has been correlated with the energy-dependent quenching (qE) in higher plants. Simulations of the difference TA kinetics reveal t
Polarized light (PL) sensitivity is relatively well studied in a large number of invertebrates and some fish species, but in most other vertebrate classes, including birds, the behavioural and physiological mechanism of PL sensitivity remains one of the big mysteries in sensory biology. Many organisms use the skylight polarization pattern as part of a sun compass for orientation, navigation and in
Enterococcus faecalis exhibits high resistance to oxidative stress. Several enzymes are responsible for this trait. The role of alkyl hydroperoxide reductase (Ahp), thiol peroxidase (Tpx), and NADH peroxidase (Npr) in oxidative stress defense was recently characterized. Enterococcus faecalis, in contrast to many other streptococci, contains a catalase (KatA), but this enzyme can only be formed whe
This thesis aimed to investigate possibilities to utilize death certificates in cancer epidemiology by analyzing nationwide databases from Sweden. Excessive information is available when investigating causes of death in cancer patients, including comorbidities and metastatic patterns. We used the Swedish Family- Cancer Database, which includes data from e.g. the Cause of Death Register and the Can
Smooth muscle cells in the urinary bladder are involved in the control of urine filling and emptying. We have used mice to study the contractile regulation of urinary bladder smooth muscle during the fetal period. We found that nerve-induced contractions are mainly dependent on muscarinic receptor activation in the newborn whereas adult bladders are equally dependent on muscarinic and purinergic r
Recent genome-wide association studies have described many loci implicated in type 2 diabetes (T2D) pathophysiology and beta-cell dysfunction but have contributed little to the understanding of the genetic basis of insulin resistance. We hypothesized that genes implicated in insulin resistance pathways might be uncovered by accounting for differences in body mass index (BMI) and potential interact
A largely extended experimental knowledge of the Cu-61(29)32 nucleus has been obtained from three experiments. Excited states in Cu-61 were produced via the fusion-evaporation reaction Si-28(Ar-36, 3p)Cu-61. In addition to the Ge array GAMMASPHERE, neutron and charged-particle detectors placed around the target position were used for high-performance particle spectroscopy. The constructed level sc
Popular Abstract in Swedish Huntingtons sjukdom (HS) är en ärftlig och dödlig sjukdom som karakteriseras av ofrivilliga, danslika rörelser vilket gjort att den i folkmun kallas för danssjuka. Diagnosen ställs när de motoriska problemen (ofrivilliga rörelserna) uppträder, vanligtvis i medelåldern, och dessa ökar sedan gradvis och den drabbade personen avlider på grund av sjukdomen efter cirka 15-25Non-motor symptoms and signs such as metabolic and psychiatric disturbances have been reported to occur early in Huntington’s disease (HD), a fatal neurodegenerative disorder caused by an expanded CAG repeat in the huntingtin gene. However, there is a lack of understanding of the underlying neurobiological mechanisms responsible for the early non-motor features. The hypothalamus has emerged as an
The starting point for this study is the transformation that the latest decade has occurred in security and defence affairs. The focal point is the big challenges that these developments have implied for national armed forces. The perspective chosen to describe and analyse this is that of professionalism, and the object of study is that of the Swedish military. The aim of the study is in broad ter
A large number of photovoltaic systems have been installed in developing countries around the world during numerous projects. The goal is often to improve the quality of life in rural areas often lacking electricity. Many of these installations provide important services such as lighting and charging of various devices. However, when the projects are finished, there is a large risk that maintenanc
Involuntary movements, or dyskinesia, represent a debilitating complication of levodopa (L-dopa) therapy for Parkinson's disease (PD). L-dopa-induced dyskinesia (LID) are ultimately experienced by the vast majority of patients. In addition, psychiatric conditions often manifested as compulsive behaviours, are emerging as a serious problem in the management of L-dopa therapy. The present review att

The endwall heat transfer characteristics of forced flow past outlet guide vanes (OGVs) in a linear cascade have been investigated by using a liquid crystal thermography (LCT) method. Due to the special design of an OGV profile, the focus of this study is emphasized on the heat transfer patterns around the leading part of a vane. The Reynolds number is kept constant at 260,000. Two attack angles o
Abstract in UndeterminedThe expected duration of initial antiparkinson monotherapy before the need for supplementation is not clearly defined for routine practice. The aim of this study was to define the length of L-dopa (L-3, 4-dihydrophenylalanine) and dopamine agonist monotherapy. The duration of monotherapy and discontinuation rates were investigated in a natural observational setting by plott
Using the large N-C approximation we have constructed the most general chiral resonance Lagrangian in the odd-intrinsic parity sector that can generate low-energy chiral constants up to O(p(6)). Integrating out the resonance fields these O(p(6)) constants are expressed in terms of resonance couplings and masses. The role of eta' is discussed and its contribution is explicitly factorized. Using the
Studies of the role of dietary factors in epithelial ovarian cancer (EOC) development have been limited, and no specific dietary factors have been consistently associated with EOC risk.
The vast majority of patients with primary dystonia are adults with focal or segmental distribution of involuntary movements. Although approximately 10% of probands have at least one first- or second-degree relative with dystonia, large families suited for linkage analysis are exceptional. After excluding mutations in known primary dystonia genes (TOR1A, THAP1, and CIZ1), whole-exome sequencing id
