PUFA from oil extracted from Nile perch viscera were enriched by selective enzymatic esterification of the free fatty acids (FFA) or by hydrolysis of ethyl esters of the fatty acids from the oil (FA-EE). Quantitative analysis was performed using RP-HPLC coupled to an evaporative light scattering detector (RP-HPLC-ELSD). The lipase from Thermomyces lanuginosus discriminated against docosahexaenoic
We used allozymes to investigate the structure of genetic variation in populations of the perennial herb Silene nutans at local (Denmark), regional (Nordic area) and wide (over a 19A degrees latitudinal gradient) geographic scales in north-western Europe. New data from Denmark were combined with data from previously studied Fennoscandian and western populations. We related patterns of nuclear vari
The effect of heat treatment on the soluble protein content in oat groats (Kerstin commercial variety) was evaluated using asymmetric flow field-flow fractionation (AF4) in combination with online multiangle light scattering (MALS) and UV detection. The AF4 method was used to separate the monomeric proteins from globulin hexamer and aggregate proteins and beta-glucan polysaccharides in the soluble
BACKGROUND:: There is a lack of health-related quality of life (HRQOL) studies in Chinese women with cervical cancer. OBJECTIVE:: The objectives of this study were to investigate the HRQOL trajectory in women with cervical cancer in Mainland China in the 9 months following diagnosis and to identify factors that influence HRQOL. METHODS:: Initially, 187 patients with cervical cancer were included i
Neurodegenerative dementia, most frequently represented by Alzheimer's disease (AD) and dementia with Lewy bodies (DLB), is often accompanied by altered sleeping patterns and excessive daytime sleepiness. Studies showing an association between the neuropeptide orexin and AD/DLB-related processes such as amyloid-β (Aβ)1-42 plaque formation, α-synuclein accumulation, and inflammation indicate that o
Purpose: To determine how image quality linked to tumor detection is affected by reducing the absorbed dose to 50% and 30% of the clinical levels represented by an average glandular dose (AGD) level of 1.3 mGy for a standard breast according to European guidelines. Materials and methods: 90 normal, unprocessed images were acquired from the screening department using a full-field digital mammograph
Two different antennas for use in implanted pacemakers are analyzed by simulation and measurement. The analysis was made with an FDTD-code. The simulations and measurements show good agreement. The SAR values for both the antennas are within the limits recommended by ICNIRP when the antenna is fed with 25 uW.
The society of today is highly dependent on technical infrastructures. Several incidents around the world the last decades have clearly highlighted the major effects technical infrastructure breakdowns have on life, health and economy of society. The vulnerabilities inherent in our technical infrastructures must be addressed in a proactive manner; it is not feasible to wait for major incidents to
Klimatförändringarna gör världen successivt varmare, förändrar nederbördsmönster, höjer havsytenivån, med mera. Klimatet har redan förändrats och i alla fall en viss fortsatt förändring är oundviklig på grund av tidigare och pågående växthusgasutsläpp. Hur stora klimatförändringarna blir på sikt beror i första hand på beslut om och åtgärder för att minska vår klimatpåverkan, det vill säga utsläpp
De stora miljö- och samhällsproblemen kommer inte ensamma. De är sammankopplade på olika sätt. Detta innebär utmaningar men ger också möjligheter att utveckla åtgärder och lösningar. Det gäller både för klimatfrågan och frågan om att motverka förlusten av biologisk mångfald och ekosystem. Kunskapens betydelse för att hantera dessa och andra aspekter är ovärderlig, såväl kring specifika frågeställn
The paper argues for the importance of seeing just how we conceptualise digital phenomena in relation to how the regulatory discourses. The Internet used to be an “information superhighway”, a “cyberspace”, or a “world wide web” often described as an empowering structure, that now has transformed to be understood in terms of “layers”, a generator of big data for a number of “platform” ventures and
Patients with rheumatoid arthritis (RA) and other inflammatory joint disorders (IJD) have increased cardiovascular disease (CVD) risk compared with the general population. In 2009, the European League Against Rheumatism (EULAR) taskforce recommended screening, identification of CVD risk factors and CVD risk management largely based on expert opinion. In view of substantial new evidence, an update
BACKGROUND: There is currently little evidence regarding the selection of patients for clinical trials in Parkinson's Disease (PD), especially those involving experimental therapies delivered using invasive techniques.OBJECTIVE: Understanding which patients are recruited will increase awareness of issues regarding parity of access to clinical trials and have an impact on the wider applicability of
La2MgNi9-related alloys are superior metal hydride battery anodes as compared to the commercial AB5 alloys. Nd-substituted La2-yNdyMgNi9 intermetallics are of particular interest because of increased diffusion rate of hydrogen and thus improved performance at high discharge currents. The present work presents in operando characterization of the LaNdMgNi9 intermetallic as anode for the nickel metal
Objective: The aim of the study was to describe patients’ experience of yoga as a treatment for hypertension, as well as their experience of living with hypertension. Design: Qualitative interview study Method and materials: In 2013–2014, in southern Sweden, patients with hypertension from three health care centres were invited to participate in a randomised controlled trial on yoga for hypertensi
Quantitative reverse transcriptase polymerase chain reaction (RT-qPCR) detection of waterborne RNA viruses generally requires concentration of large water volumes due to low virus levels. A common approach is to use dead-end ultrafiltration followed by precipitation with polyethylene glycol. However, this procedure often leads to the co-concentration of PCR inhibitors that impairs the limit of det
