In this overview the technique of accelerator mass spectrometry (AMS) and its use are described. AMS is a highly sensitive method of counting atoms. It is used to detect very low concentrations of natural isotopic abundances (typically in the range between 10(-12) and 10(-16)) of both radionuclides and stable nuclides. The main advantages of AMS compared to conventional radiometric methods are the
We present a microgeographic analysis of 34 allozyme loci and the control region of mitochondrial DNA (mtDNA) in the common vole Microtus arvalis (Pallas, 1779), performed to assess the effects of environmental heterogeneity on the distribution of genetic variation among populations in the Biebrza river valley, NE Poland The common vole occurs there in two types of habitat open grassland and pastu
Objectives: To assess the relationships of somatic and anxiety symptoms of depression with functional disability in a sample of older adults with late life depression. Method: Data were analyzed from 78 older adults aged 65–88 with current major depression. Somatic and anxiety symptoms from the 24-item Hamilton Depression Rating Scale (HDRS) were summed to create variables measuring severity of th
Närståendes närvaro hos patienter som är kritiskt sjuka underlättar enligt studier patienternas vistelse på intensivvårdsavdelningen. För att stödja och tillhandahålla information till de närstående bör personal på intensivvårdsavdelningar vara medvetna om närståendes uppfattningar. I Kanada har ett enkätformulär FS-ICU utvecklats för att undersöka närståendes tillfredsställelse med vården och med
Trots att kunskaperna om och intresset för smärta och smärtlindring har ökat de senaste åren drabbas fortfarande många patienter en inadekvat smärtlindring och många patienter förväntar sig smärta postoperativt. Syftet med denna studie var att undersöka kvinnor i olika åldrar avseende förväntningar och upplevelser av postoperativ smärta och smärtlindring samt hur stor betydelse den preoperativa in
1. Five groups of male Sprague Dawley rats were given for 6 months a diet with high protein and fat contents but a very low dietary fibre content (group B), and this diet mixed with (g/kg) 50 low-methoxyl pectin (group L), 50 high-methoxyl pectin (group H), 50 guar gum (group G) and 200 wheat bran (group WB, corresponding to 100 wheat fibre) respectively. 2. The weight increment was significantly
The study aims to understand the influence of environmental and lifestyle factors and more specifically the role of tobacco smoke–infused water (tuibur) on Helicobacter pylori infection. It was a cross-sectional study to measure the epidemiological risk factors associated with H. pylori infection among the tribal population in Northeast India. Endoscopic samples were collected from the antrum regi
Objective: The Attempted Suicide Short Intervention Program (ASSIP) was adapted for hospital delivery and to address substance use problems as well as evaluated for feasibility, acceptability, and therapist fidelity in a series of preparatory steps (n = 28) and in a pilot randomized controlled trial, RCT (n = 34). Method: In the RCT, patients with suicide attempts and substance use problem(s) with
Titanium dioxide (TiO2) is a unique material for biosensing applications due to its capability of hosting enzymes. For the first time, we show that TiO2 can accumulate reactive oxygen species (ROS) under daylight irradiation and can support the catalytic cycle of horseradish peroxidase (HRP) without the need of H2O2 to be present in the solution. Phenolic compounds, such as hydroquinone (HQ) and 4
By performing whole-genome sequencing in a Swedish cohort of 71 parent-offspring trios, in which the child in each family is affected by systemic lupus erythematosus (SLE, OMIM 152700), we investigated the contribution of de novo variants to risk of SLE. We found de novo single nucleotide variants (SNVs) to be significantly enriched in gene promoters in SLE patients compared with healthy controls
This work presents a rapid, selective and sensitive automated sequential injection flow system with a capacitive biosensor for detection of the mecA gene (the model chosen for this study), which emerges from methicillin-resistant Staphylococcus aureus. A DNA-based 25-mer capture probe was immobilized on the surface of a gold electrode which was integrated in the capacitive sensor system. A constan
Background In the early 1980s, a preservative containing a mixture of methylchloroisothiazolinone (MCI) and methylisothiazolinone (MI) in a ratio of 3:1 was introduced. This mixture (mix) has been patch tested at 100 ppm (0.01%) worldwide and at 200 ppm (0.02%) in Sweden since 1986 and also in the European baseline series since 2014. Objective A new aqueous mix of MCI 0.015% and MI 0.2% was compar
Purpose This study explored the role of several psychological factors in professional quality of life in nurses. Specifically, we tried to clarify the relationships between several dimensions of empathy, self-compassion, and psychological inflexibility, and positive (compassion satisfaction) and negative (burnout and compassion fatigue) domains of professional quality of life. Methods Using a cros
The diversity of bacteriophages is likely unparalleled in the biome due to the immense variety of hosts and the multitude of viruses that infect them. Recent efforts have led to description at the genomic level of numerous bacteriophages that infect the Actinobacteria, but relatively little is known about those infecting other prokaryotic phyla, such as the purple non-sulfur photosynthetic α-prote
A proteoglycan is a protein with at least one glycosidic chain or glycosaminoglycan (GAG) covalently bound to it. Since a common linker between the core protein and the GAG chain has a xylose present, the biosynthesis of GAGs can be primed using xylosides containing hydrophobic aglycons providing that these xylosides are capable of penetrating the cell membrane. 2-naphthyl β-D-xylopyranoside prim
