The essential protein Cdc13p binds the single-stranded telomeric 3' overhangs in Saccharomyces cerevisiae and takes part in the regulation of telomere length. The DNA-binding domain (DBD) of Cdc13p is structurally established by an oligonucleotide/oligosaccharide-binding (OB)-fold domain. The sequence homolog in Saccharomyces castellii (scasCDC13) was characterized previously, and the full-length
This study uses a cognitive test score, the Swedish Military Enlistment test taken at age 18, to identify whether the ethnic employment and income gap in Sweden is caused by a pre-market skill gap and/or ethnic discrimination. The employment gap and income gap are estimated for males born in Sweden with different ethnic backgrounds: their parents were born in Sweden or in southern Europe or outsid
Adult neurogenesis is impaired in the hippocampus of transgenic R6 mouse models of Huntington's disease (HD). The phenotypes of R6 transgenic mice mimic several symptoms and signs of the disease (Li et al., 2005). They exhibit neurological and endocrine changes resembling some symptoms seen in humans. The reduction in neurogenesis is only apparent in the dentate gyrus as the number of newborn neur
To resist infections, robust defense mechanisms of the airways are essential. Retinoic acid promotes differentiation and maintains the phenotypic characteristics of bronchial epithelium. In addition, it induces the expression of the antibacterial growth factor midkine (MK). In the present study, we explored the expression and antibacterial activity of MK in an airway context. MK was detected in br
Platelets contribute to blood coagulation at sites of vascular injury and to the recruitment of leukocytes at sites of inflammation. Under pathological conditions, platelets are involved in numerous diseases and clinical complications, such as deep venous thrombosis, embolism and atherosclerosis. But so far, little is known about the mechanisms of inflammation in large veins and the role of platel
Biochemical markers for osteoarthritis (OA) may serve different purposes. Since markers reflect ongoing dynamic metabolic processes in the joint tissues (cartilage, synovium, bone, etc.), they are most likely to be useful to predict prognosis and response to treatment, to monitor response to treatment, and for disease staging. Markers are currently being used at the research level for these purpos
Salt-induced elevation of the endogenous digitalis like sodium pump ligand marinobufagenin (MBG) in the Dahl salt-sensitive rats resulted in elevated blood pressure (BP). Here, we tested, in humans, whether MBG levels are related to ambulatory 24-h BP (ABP), controlled long-term increase of salt-intake induces changes in MBG and any salt-induced change in MBG is related to salt sensitivity.
This thesis explores the impact of medical migration on the healthcare crisis in East Africa. With a qualitative research design of ten semi-structured interviews it shall help to understand the relationship between medical migration and the healthcare crisis in East Africa. Accordingly, by interviewing doctors with ties to East Africa and relevant experiences for the topic of study, the following
BACKGROUND: Recently, a -168A-->G polymorphism in the MHC class II transactivator gene (MHC2TA) was shown to be associated with increased susceptibility to myocardial infarction (MI). AIM: To confirm the association between the MHC2TA -168A-->G polymorphism and MI and to study its putative role for microalbuminuria, the metabolic syndrome (MetS) and cardiovascular mortality. MATERIALS AND METHODS:
Serine proteases play a central role in defense against pathogens by regulating processes such as blood clotting, melanization of injured surfaces, and proteolytic activation of signaling pathways involved in innate immunity. Here, we present the functional characterization of the Drosophila serine protease Sp7 (CG3006) by inducible RNA interference. We show that Sp7 is constitutively expressed in
Magnesium chelatase inserts Mg2+ into protoporphyrin IX and is the first unique enzyme of the chlorophyll biosynthetic pathway. It is a heterotrimeric enzyme, composed of I- (40 kDa), D- (70 kDa) and H- (140 kDa) subunits. The I- and D-proteins belong to the family of AAA(+) (ATPases associated with various cellular activities), but only I-subunit hydrolyses ATP to ADP. The D-subunits provide a pl
Denna uppsats undersöker de levda erfarenheterna hos japanska migranter i Sverige, en grupp som omfattar cirka 4 600 individer, varav nästan 80 procent har valt att permanent bosätta sig i Sverige. De återstående 20 procenten är tillfälliga invånare, som studenter, forskare eller utstationerade chefer, verksamma i något av de cirka 200 japanskägda företagen i landet. Till skillnad från andra europThis thesis explores the lived experiences of Japanese migrants to Sweden, a demographic that includes approximately 4,600 individuals, of whom nearly 80 percent chose to settle permanently in Sweden. The remaining 20 percent are temporary residents, as students, researchers, or as expatriate managers, working in one of the roughly 200 Japanese-owned companies in the country. In contrast to other
An important manifestation of severe COVID-19 is the ARDS-like lung injury that is associated with vascular endothelialitis, thrombosis, and angiogenesis. The intravascular innate immune system (IIIS), including the complement, contact, coagulation, and fibrinolysis systems, which is crucial for recognizing and eliminating microorganisms and debris in the body, is likely to be involved in the path
Background: The classic Bernard-Soulier syndrome (BSS) is a rare inherited thrombocytopenia (IT) associated with severe thrombocytopenia, giant platelets, and bleeding tendency caused by homozygous or compound heterozygous variants in GP1BA, GP1BB, or GP9. Monoallelic BSS (mBSS) associated with mild asymptomatic macrothrombocytopenia caused by heterozygous variants in GP1BA or GP1BB may be a frequ
The polymerization of amino acids into proteins occurs on ribosomes, with the rate influenced by the amino acids being polymerized. The imino acid proline is a poor donor and acceptor for peptide-bond formation, such that translational stalling occurs when three or more consecutive prolines (PPP) are encountered by the ribosome. In bacteria, stalling at PPP motifs is rescued by the elongation fact
Understanding the role of technology characteristics and the context in the diffusion of new energy technologies is important for assessing feasibility of climate mitigation. We examine the historical adoption of nuclear power as a case of a complex large scale energy technology. We conduct an event history analysis of grid connections of first sizable commercial nuclear power reactors in 79 count
SpoVD and PBP4b are structurally very similar high-molecular-weight, class B penicillin-binding proteins produced early during sporulation in Bacillus subtilis. SpoVD is known to be essential for endospore cortex synthesis and thereby the production of heat-resistant spores. The role of PBP4b is still enigmatic. Both proteins are synthesized in the cytoplasm of the mother cell. PBP4b remains in th
