Precise design of architected functional ceramics hinges on a fundamental understanding of their structure-property relations. Functional properties in ferroelectric ceramics are known to be strongly nonlinear with respect to electric-field amplitude due to microscopic mechanisms, such as domain-switching. However, unlike monolithic ceramics, since electric-field distribution within architected fe

Sammanfattning Kapitel 2 Presentation av ett nytt tumör-behandlingskoncept med ”Pre-kirurgisk intermittent ultrahypofraktionerad strålbehandling” (PSiRT) ”kombinerad med immunterapi” (PSiRIT), särskilt immun¬kontrollpunktshämmare (anti-CTLA4 och anti-PD-1).Intermittent ultrahypofraktionerad strålbehandling innebär:• Optimal absorberad dos 6–8 Gy per fraktion • Doser >10 Gy kan öka immunosuppressiv

Following the outbreak of new media technologies, researchers in museum studies have acknowledged the increasing importance of digital content creation for museums. Today, Social Media provides museums with the opportunity to engage with their audiences beyond museum walls and pursue their organizational mission in innovative ways. Despite a growing interest in the organizational changes that make

Antimicrobial peptides (AMPs) are a diverse family of peptides that defend the mucosal surfaces of the oral cavity and other locations. Many AMPs have multiple functions and properties that influence aspects of innate defense and colonization by microorganisms. The human oral cavity is home to the second-most diverse microbiome, and the health of the mouth is influenced by the presence of these ba

MRI-based biophysical models are typically validated by comparison to ex-vivo histology of fixed tissue. The fixation process itself and the accompanied autolysis processes strongly modify tissue composition, and lead to MR signal changes, making the validation of biophysical models for in vivo MRI particularly challenging. To better understand the temporal evolution of the fixation process within

Background: In order to increase coverage in the organized cervical screening program, self-sampling with HPV analyses has been suggested. Objectives: The aim was to compare human papillomavirus (HPV) mRNA detection in vaginal and urine self-collected samples with clinician-taken cervical samples and the corresponding clinician-taken histological specimens. Study design: Self-collected vaginal, ur

Lignin is the second most abundant naturally produced organic polymer on earth. Lignin‐modifying enzymes (LMEs) are produced by the white‐rot fungi as products of secondary metabolism, since lignin degradation does not provide any energy to the fungus. The main oxidative enzymes include the peroxidases‐lignin peroxidase (LiP) (diarylpropane: oxygen, hydrogen peroxide oxidoreductase), manganese per

Occupational well-being is a central issue underpinning factors that constitute a good life. This study aimed to explore occupational well-being among Middle Eastern immigrants to Sweden, as reflected in the occupations performed in the context of psychosocial health care. Ten participants experiencing mental health issues, who received occupation-based rehabilitation, were interviewed. Grounded t

Nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) are neuronal survival molecules which utilize the Trk family of tyrosine kinase receptors. Using double-label in situ hybridization, we demonstrate that mRNAs for BDNF and its high-affinity receptor TrkB are coexpressed in hippocampal and cortical neurons. Also, a large number of neurons in these areas coexpress NGF and BDNF mR

Alpha-synuclein phosphorylated at serine 129 (S129) is highly elevated in Parkinson's disease patients where it mainly accumulates in the Lewy bodies. Several groups have studied the role of phosphorylation at the S129 in alpha-synuclein in a rat model for Parkinson's disease using recombinant adeno-associated viral (rAAV) vectors. The results obtained are inconsistent and accordingly the role of

Objectives: This paper explores factors important for return to work (RTW) in people who have sustained a serious hand injury. Participants: Forty people aged 19-64, with a severe or major hand injury were recruited consecutively during 2005-2007. Methods: A self-administered and study specific questionnaire, including demographic data and standardised questionnaires for function, disability,

Saturated straight- and branched-chain 3-hydroxy fatty acids (3-OH FAs) of 10-18 carbon chain lengths were determined in saliva from 27 individuals with chronic periodontitis and 18 healthy individuals by using gas chromatography-tandem mass spectrometry. Of the 14 different 3-OH FAs detected, 3-OH-C-i17:0 was the most abundant in the periodontitis samples while 3-OH-C-14:0 was the most abundant i

Antibiotic resistance in pneumococci is due to the spread of strains belonging to a limited number of clones. The Spain(9v)-3 clone of sequence type (ST)156 is one of the most successful clones with reduced susceptibility to penicillin [pneumococci nonsusceptible to penicillin (PNSP)]. In Sweden during 2000-2003, a dramatic increase in the number of PNSP isolates was observed. Molecular characteri

BACKGROUND: Despite screening of blood donors, hepatitis C virus (HCV) infection can occur in patients who receive multiple transfusions. OBJECTIVE: To clarify mechanisms of nosocomial transmission of HCV. DESIGN: Epidemiologic and molecular analyses of hepatitis C outbreaks. SETTING: Pediatric oncology ward. PATIENTS: Children with cancer. MEASUREMENTS: Epidemiologic analysis, HCV RNA detection,

The use of trimethylsilyl (TMS)-derivatisation for determining muramic acid in environmental and clinical samples by gas chromatography-mass spectrometry provides high detection sensitivity; however, questions have been raised as concerns the chemical structure of the entity giving the strong signal of m/z 185. In the present communication we present evidence that this entity results from the form
