Using protons in the MeV range as excitation source and a high resolution Si(Li) detector,X-ray emission spectroscopy is shown to be capable of analyzing many elements with Z > 15 simultaneously at the 10-12 g level. This work discusses a theoretical lower limit of detection at moderate proton energies and gives examples of possible applications: analysis of the elemental composition of air-borne
Background and Purpose— Although stroke is strongly associated with hypertension, some individuals with normal blood pressure (BP) experience a stroke. This prospective study explored risk factors for stroke in subjects with normal BP. Methods— A total of 11 228 men and 17 174 women, 45 to 73 years old, were examined in a population-based cohort study. Normal BP was defined as BP <140/90 mm Hg an
Electron paramagnetic resonance (EPR) spectroscopy is one of the major techniques used to analyse the structure and function of the water oxidising complex (WOC) in Photosystem II. The discovery of an EPR signal from the S0 state has opened the way for new experiments, aiming to characterise the S0 state and elucidate the differences between the different S states. We present a review of the bioch
New radiative lifetimes of eight levels in Pr III have been measured using the time-resolved laser-induced fluorescence method. A tunable frequency-doubled dye laser with 1-ns pulse duration was used to excite selectively doubly ionized praseodymium in a laser-produced plasma. The experimental results agree generally well with theoretical data, provided core-polarization effects are considered in
Introduction: Monitoring replacement therapy with standard and extended half-life (EHL) products is challenging, since one-stage assay (OSA) and chromogenic substrate assay (CSA) results may differ significantly. Recent recommendations include local validation of each new product with recovery within 20–30%, depending on activity level. Aim: To validate factor VIII (FVIII) activity for monitoring
Diabetes impacts on brain metabolism, structure and function. Alterations in brain metabolism have been observed in obesity and diabetes models induced by exposure to diets rich in saturated fat and/or sugar and have been linked to memory impairment. However, it remains to be determined whether brain dysfunction induced by obesogenic diets results from permanent brain alterations. We tested the hy
INTRODUCTION: Breast cancer, a leading female cancer worldwide, can be influenced by mitochondrial dysfunction. Dysregulation of mitochondria by the nuclear genome may cause breast cancer initiation and progression. However, the comprehensive investigation of mitochondrial-related genes as prognostic marker for the overall survival of early-stage breast cancer patients is still limited.METHODS: To
The Sensory Processing Measure, second edition (SPM-2), is an American assessment guiding person-centered sensory processing interventions, but it lacks Swedish adaptation for occupational therapists. In eight phases, this study translated the SPM-2 into Swedish and assessed its face validity and preliminary psychometric properties, including internal consistency and inter-scale/item correlations.
INTRODUCTION: 22q11.2 deletion syndrome (22qDS) has been associated with varying levels of social impairments, and with atypical visual scanning of faces. The present study explored whether self-reported sensitivity to eye contact might be related to these phenomena.METHOD: Individuals with confirmed 22qDS were interviewed about their experience and possible discomfort with eye contact. In cases w
Quantification of face-to-face interaction can provide highly relevant information in cognitive and psychological science research. Current commercial glint-dependent solutions suffer from several disadvantages and limitations when applied in face-to-face interaction, including data loss, parallax errors, the inconvenience and distracting effect of wearables, and/or the need for several cameras to
Neuropsychiatric and neurodevelopmental disorders are often associated with coordination problems. Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) constitutes a specific example of acute and complex symptomatology that includes difficulties with motor control. The present proof-of-concept study aimed at testing a new, bespoke tablet-based motor coordination test named SpaceSwipe, providing
Inflammation and insulin resistance are associated with increased mortality in the general population. However, it remains unclear how physical activity and proinflammatory/hyperinsulinemic diets influence overall survival in prostate cancer patients. We analyzed 4779 men with nonmetastatic prostate cancer from the Health Professionals Follow-up Study. Postdiagnosis physical activity and diet were
Five prompt proton decay lines have been identified between deformed states in Cu-59 and three spherical states in Ni-58 by means of high-resolution in-beam particle-gammagamma coincidence spectroscopy. The GAMMASPHERE array coupled to dedicated ancillary detectors including four DeltaE-E silicon strip detectors was used to study high-spin states in Cu-59. The multiple discrete proton lines are fo
This study aimed to determine the effect of supplementation with conjugated linoleic acids (CLAs) plus n-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFAs) on body composition, adiposity, and hormone levels in young and older, lean and obese men. Young (31.4 +/- 3.9 years) lean (BMI, 23.6 +/- 1.5 kg/m(2); n = 13) and obese (BMI, 32.4 +/- 1.9 kg/m(2); n = 12) and older (56.5 +/- 4.6 years) lea
Due to decreased functional capacity as well as high environmental demands there is a risk of diminishing activity outside home in very old age (age 80+). In order to explore differences according to functional limitations (FL) among very old people with respect to frequency of activity, perceived health, overall perception of neighbourhood environment, and perceived problems in the pedestrian env
This study estimated the risk of second primary malignancies after Hodgkin's lymphoma (HL) in relation to family history of cancer, age at diagnosis and latency, among 6946 patients treated for HL in Sweden in 1965-1995 identified through the Swedish Cancer Register (SCR). First-degree relatives (FDRs) to the HL patients and their malignancies were then ascertained together with their malignancies
Objective: Low adipocyte IRS-1 protein expression is a biomarker for insulin resistance and early atherosclerosis. However, whether IRS-1 protein expression is related to systemic arterial stiffness, is unknown. Methods and results: Ten non-diabetic male subjects with low adipocyte IRS-1 protein expression (NIRS) were matched with 10 non-diabetic males with normal IRS-1 protein expression (NIRS).
In Europe, azacitidine is the only hypomethylating agent approved for the treatment of patients with int-2-/high-risk myelodysplastic syndromes, offering significantly improved survival compared with conventional care. However, not all patients treated with azacitidine respond to treatment, and the vast majority of responders subsequently relapse. Currently, no standard care regimens have been est
The structure and stability of the lamellar liquid crystal formed by the surfactant sodium bis-2ethylhexyl sulfosuccinate (AOT) in water is perturbed by small amounts of the substituted acrylamides N-isopropyl, N,N-diethyl, N-acryloylmorpholine, and N,N-dimethyl methacrylamide, as revealed by small angle X-ray scattering (SAXS), deuterium NMR, and microscopy. These molecules are water soluble and
