Dark-grown tigrina-d(12) mutants of barley (Hordeum vulgare L.) accumulate abnormally high amounts of the chlorophyll intermediate protochlorophyllide. In light dark cycles this leads to necrotic segments of the seedling leaves and lethality due to photodynamic damage by the excessive protochlorophyllide accumulated in the dark period. Upon inhibition of the early chlorophyll biosynthetic enzyme,

A gas chromatographic-ion trap tandem mass spectrometric method was developed for the quantification of muramic acid, a marker of bacterial peptidoglycan, in environmental and clinical specimens. Samples (bacteria, house dust and urine) were heated in methanolic hydrochloric acid overnight and extracted with hexane for removal of hydrophobic compounds. The aqueous phase was evaporated and heated i

Background. Of the estimated one million Papanicolaou (pap) smears performed annually in Sweden, about 4% show any degree of abnormality. Approximately, 1% of these cases contain moderate or severe atypia (high-grade squamous intraepithelial lesions) and the rest contain low-grade atypia. Recommendations for the management of minor abnormalities vary in various parts of Sweden. Generally, a second

Objective: To evaluate aspects of internal scale validity and reliability of the Swedish version of the Impact on Participation and Autonomy questionnaire (IPA-S) for use in people with spinal cord injury. Subjects: A total of 161 persons with spinal cord injury. Method. IPA-S psychometric properties were evaluated using Rasch rating scale analysis. Results: The results show that the IPA-S has 27

This study analyzes (a) the relation between injury severities, the age of the bicyclist and the speed environment at accident locations (mean travel speed of the traffic flow involved in the accident) where a bicyclist was struck by a motorized vehicle and (b) how these relations differ from those for struck pedestrians. Accident data from Sweden for the years 2004-2008 was used to identify accid

Our study aimed to describe the clinical outcome of patients with superficial soft-tissue sarcomas (SSTS), define prognostic factors and provide evidence for a rational surveillance scheme.

Objective: To explore the views and experiences of providing assistance and treatment of sexually transmitted infections to same-sex practicing male clients among service providers at pharmacies and drugstores in Dar es Salaam, Tanzania. Previous research suggests that sexually transmitted infections are an increasing concern for this population. Due to stigma and discrimination, men who have sex

We have shown recently that PrkC, which is involved in developmental processes in Bacillus subtilis, is a Ser/Thr kinase with features of the receptor kinase family of eukaryotic Hanks kinases. In this study, we expressed and purified from Escherichia coli the cytoplasmic domain of PrkC containing the kinase and a short juxtamembrane region. This fragment, which we designate PrkCc, undergoes autop

The printed circuit boards basis of electronic equipment have seen a rapid growth in recent years and played a significant role in modern life. Nowadays, the fact that electronic devices upgrade quickly necessitates a proper management of waste printed circuit boards. Non-destructive desoldering of waste printed circuit boards becomes the first and the most crucial step towards recycling electroni

Even with the availability of targeted drugs, allogeneic hematopoietic cell transplantation (allo-HCT) is the only therapy with curative potential for patients with CLL. Cure can be assessed by comparing long-term survival of patients to the matched general population. Using data from 2589 patients who received allo-HCT between 2000 and 2010, we used landmark analyses and methods from relative sur

P-type ATPases from the P4 subfamily (P4-ATPases) are energy-dependent transporters, which are thought to establish lipid asymmetry in eukaryotic cell membranes. Together with their Cdc50 accessory subunits, P4-ATPases couple ATP hydrolysis to lipid transport from the exoplasmic to the cytoplasmic leaflet of plasma membranes, late Golgi membranes, and endosomes. To gain insights into the structure

Background and purpose. The purpose of this study was to evaluate the performance of gantry angle optimisation (GAO) compared to equidistant beam geometry for two inverse treatment planning systems (TPSs) by utilising the information obtained from a range of treatment plans. Material and methods. The comparison was based on treatment plans generated for four different head and neck (H&N) cance

In 2000, the Clinton Administration in the U.S. adopted the Commodity Futures Modernization Act, which deregulated the U.S. trade with financial instruments on commodity markets. With respect to this adoption, it has been regarded as one catalyst for the Global food crisis 2008, where millions of individuals lacked provision and access to agricultural products and nutrition. From the perspective o

Hittills har över 50 miljoner ton e-avfall genererats globalt (World Economic Forum, 2019), vilket väcker frågan om den cirkulära ekonomins roll i kampen mot klimatförändringarna (Ellen MacArthur Foundation, 2021). I detta examensarbete undersöks möjligheterna för Axis Communications att införa ett system i USA för att ta tillbaka produkter som tagits ur bruk och återvinna dem. Inom detta område So far, over 50 million tonnes of e-waste have been generated globally (World Economic Forum, 2019), raising the question of the role of circular economy in combating climate change (Ellen MacArthur Foundation, 2021). This thesis explores the opportunities for Axis Communications to introduce a take back system for recycling decommissioned products in the US. Within this scope, several areas are

This thesis explores the socially constructed phenomenon that has arisen as a result of the proliferation of social network sites that has penetrated our daily lives. The qualitative study analysed how university students experienced the global outage of Facebook, Instagram and, WhatsApp on October 4th, 2021, because of the Meta-owned ecosystem of social media. Moreover, the study examined how 2 g

Due to a warming climate, tundra ecosystems are subject to shrub and treeline expansions which could lead to increased above- but decreased belowground carbon (C) stocks. An observed low soil C stock in some subarctic forests and tall shrublands has been suggested to be induced by priming of organic matter decomposition, possibly mediated by ectomycorrhizal fungi. On the other hand, the higher bel
