Exploring substrate specificities of a recombinant Rhizopus oryzae lipase in biodiesel synthesis

The alcoholysis of triolein was used to explore the specific features of a recombinant Rhizopus oryzae lipase (rROL) for biodiesel synthesis. For this purpose, different acylglycerols were compared as substrates in lipase-catalysed transesterification. rROL was shown to exhibit a higher specificity towards 1-monoolein than triolein compared to other R. oryzae lipases, being more than 4-fold more s

Lead(ii) soaps : Crystal structures, polymorphism, and solid and liquid mesophases

The long-chain members of the lead(ii) alkanoate series or soaps, from octanoate to octadecanoate, have been thoroughly characterized by means of XRD, PDF analysis, DSC, FTIR, ssNMR and other techniques, in all their phases and mesophases. The crystal structures at room temperature of all of the members of the series are now solved, showing the existence of two polymorphic forms in the room temper

Redox-Driven Migration of Copper Ions in the Cu-CHA Zeolite as Shown by the InSitu PXRD/XANES Technique

Using quasi-simultaneous insitu PXRD and XANES, the direct correlation between the oxidation state of Cu ions in the commercially relevant deNOx NH3-SCR zeolite catalyst Cu-CHA and the Cu ion migration in the zeolitic pores was revealed during catalytic activation experiments. A comparison with recent reports further reveals the high sensitivity of the redox-active centers concerning heating rates

Migraine associated with altitude : results from a population-based study in Nepal

Background and purpose: A 1988 pilot study in Peru suggested an association between migraine and chronic exposure to high altitude. This study provides epidemiological evidence corroborating this. Methods: In a cross-sectional nationwide population-based study, a representative sample of Nepali-speaking adults were recruited through stratified multistage cluster sampling. They were visited at home

Sensitivity of Sentinel-1 backscatter to characteristics of buildings

In this study, Sentinel-1 interferometric wide swath (IW) mode backscatter is analysed with respect to physical parameters of buildings in Tallinn, Estonia. Dependence on height, alignment, density, shape, and material is shown and discussed. Distribution of backscatter was estimated with respect to each of the parameters, and a correlation matrix of all physical parameters and backscatter values

Monomeric and fibrillar α-synuclein exert opposite effects on the catalytic cycle that promotes the proliferation of Aβ42 aggregates

The coaggregation of the amyloid-β peptide (Aβ) and α-synuclein is commonly observed in a range of neurodegenerative disorders, including Alzheimer’s and Parkinson’s diseases. The complex interplay between Aβ and α-synuclein has led to seemingly contradictory results on whether α-synuclein promotes or inhibits Aβ aggregation. Here, we show how these conflicts can be rationalized and resolved by de

Doctors Doing Gender at Eye Clinics—Gender Constructions in Relation to Waiting Times for Cataract Extractions in Sweden

Why do eye clinics differ in their waiting times for women’s and men’s access to cataract extraction (CE)/“grå starroperation”? Taking a doing-gender perspective as the starting point, this study explores how gender constructions embedded in Swedish eye clinics contribute to longer waiting times for women than for men. Focus group interviews were conducted with doctors at two Swedish eye clinics:

Slipped capital femoral epiphysis : A population-based study

Background: Slipped capital femoral epiphysis (SCFE) is the most common hip disorder in children 9-15 years old. This is a population-based study in Sweden presenting the epidemiology for SCFE. Methods: In a prospective cohort study, we analysed pre- and postoperative radiographs, medical records for all children treated for SCFE in Sweden 2007-2013, demographic data, severity of slip and surgical

Protein S100B in umbilical cord blood as a potential biomarker of hypoxic-ischemic encephalopathy in asphyxiated newborns

BACKGROUND: Neonatal hypoxic ischemic encephalopathy (HIE) is a devastating condition resulting from a sustained lack of oxygen during birth. The interest in identifying a relevant biomarker of HIE has thrown into limelight the role of protein S100B as a clinical diagnostic marker of hypoxic brain damage in neonates.AIMS: To evaluate the diagnostic value of protein S100B, measured in umbilical cor

Trends in treatment with antipsychotic medication in relation to national directives, in people with dementia - a review of the Swedish context

Background: The aim of this study was to explore trends in treatment with antipsychotic medication in Swedish dementia care in nursing homes as reported in the most recent empirical studies on the topic, and to relate these trends to directives from the national authorities. Methods: The study included two scoping review studies based on searches of electronic databases as well as the Swedish dire

Sustained versus standard inflations during neonatal resuscitation to prevent mortality and improve respiratory outcomes

Background: At birth, infants' lungs are fluid-filled. For newborns to have a successful transition, this fluid must be replaced by air to enable effective breathing. Some infants are judged to have inadequate breathing at birth and are resuscitated with positive pressure ventilation (PPV). Giving prolonged (sustained) inflations at the start of PPV may help clear lung fluid and establish gas volu

Solute transfer in on-line analytical flow-through dialyzers

Mass transfer in infinite parallel-plate dialyzers with co-flow between sample and detector streams is discussed for three different theoretical models. Analytical solutions with coupled diffusion and membrane transfer equations were obtained for plug flow in both channels. The finite-difference approximation method was used to obtain numerical solutions for a laminar-flow regime. Results obtained

Clonal Hematopoiesis and risk of atherosclerotic cardiovascular disease

BACKGROUND Clonal hematopoiesis of indeterminate potential (CHIP), which is defined as the presence of an expanded somatic blood-cell clone in persons without other hematologic abnormalities, is common among older persons and is associated with an increased risk of hematologic cancer. We previously found preliminary evidence for an association between CHIP and atherosclerotic cardiovascular diseas

Teachers’ Assessment and grading Practices in upper secondary Science Classrooms in Sweden : The Teachers’ and Students’ Perspectives

This dissertation acknowledges that accountability of educators for the grades they assign is a part of the foundation for a meritocratic society, based on fairness in judging merit and, therefore, in assigning grades. In this view, any grade obtained by any student must be both reliable and valid. This, in turn, implies that the process of assessment of students’ work on which the grade is based
