We describe a compact and practically debris-free laser-plasma x-ray source suitable for proximity lithography. The source is based on a microscopic fluorocarbon continuous liquid jet droplet target, generating high-brightness lambda=1.2-1.7 nm x-ray emission with similar to 5% conversion efficiency. This target type has the advantages of producing only negligible amounts of debris, and being rege
The development of multicellular organisms is associated with extensive rearrangements of tissues and cell sheets. The driving force for these rearrangements is generated mostly by the actin cytoskeleton. In order to permit the reproducible development of a specific body plan, dynamic reorganization of the actin cytoskeleton must be precisely coordinated in space and time. GTP-exchange factors tha
BACKGROUND: Irritable bowel syndrome (IBS) is characterized by chronic gastrointestinal dysfunction in the absence of detectable organic disease. The recently developed technique, video capsule endoscopy (CE), has been shown to be much more sensitive than traditional enterography in detecting mucosal changes in the small intestine. This study was performed to see if any earlier, not detectable by
Purpose: To study early signs of neuronal and glial differentiation in the human embryonic retina. Materials and Methods: 6.5-to 8-week-old human embryos were obtained from elective abortions. The neuroretinas were kept in culture as full-thickness sheets for 7-42 days. Results: The control retinas consisted of a neuroblast cell layer and a thin marginal zone. Most explants displayed presence of r
We used multilevel models to investigate whether the odds of coronary heart disease (CHD) is higher in patients with diabetes mellitus (DM) living in deprived neighborhoods versus those living in wealthy neighborhoods. The Swedish nationwide prescription register was used to identify 334,000 patients aged 30 years and older with DM. The OR of CHD was significantly higher among patients with DM liv
BACKGROUND: Treatment of diabetic foot ulcers includes a number of different regimes such as glycaemic control, re-vascularization, surgical, local wound treatment, offloading and other non-surgical treatments. Although considered the standard of care, the scientific evidence behind the various debridements used is scarce. This presentation will focus on debridement and V.A.C. Therapy, two treatme
This paper presents a new procedure for assessing off-axis refractive errors; in this case, oblique astigmatism. By using photorefraction to objectively measure the off-axis refraction, it is possible to identify and provide eccentric correction that results in better image quality for the preferred retinal location (PRL) or the trained retinal location (TRL). This paper describes the case of a 56
The purpose of this paper is to review the incidence of upper-body morbidity (arm and breast symptoms, impairments, and lymphedema), methods for diagnosis, and prevention and treatment strategies. It was also the purpose to highlight the evidence base for integration of prospective surveillance for upper-body morbidity within standard clinical care of women with breast cancer. Between 10% and 64%
OBJECTIVE: Accurate distinction between dementia subtypes is important for patient care and pharmacological treatment. Continuing systematic comparisons of clinical and neuropathological dementia diagnoses may provide a basis for further improvement of the diagnostic procedure. The purpose of this study was to investigate concordance between clinical dementia diagnosis and neuropathological findin
Background: The transfusion of red blood cells (RBCs) after cardiac surgery has been associated with increased long-term mortality. This study reexamines this hypothesis by including pre-operative hemoglobin (Hb) levels and renal function in the analysis. Methods: A retrospective single-center study was performed including 5261 coronary artery bypass grafting (CABG) patients in a Cox proportional
The relationship between inflammation and proteolytic activation in pancreatitis is an unresolved issue in pancreatology. The purpose of this study was to define the influence of neutrophils on trypsinogen activation in severe AP. Pancreatitis was induced by infusion of taurocholate into the pancreatic duct in C57BL/6 mice. For neutrophil depletion, an anti-Gr-1 antibody was administered before pa
We investigated element accumulation in vesicles of the arbuscular mycorrhizal (AM) fungus Glomus intraradices, extracted from the roots of inoculated leek plants. The elemental composition (elements heavier than Mg) was quantified using particle-induced X-ray emission (PIXE), in combination with scanning transmission ion microscopy (STIM). In vesicles, P was the most abundant of the elements anal
Since the 1980s, prenatal detection of cleft lip with or without cleft palate (CLP) is possible with a transabdominal ultrasound. The improvement of prenatal detection has resulted in an increased demand for prenatal information and counselling. The aim of this study was to, by means of a questionnaire, evaluate how families, who received the diagnosis prenatally and postnatally, respectively, thi
PURPOSE: To investigate if resting-state functional MRI (fMRI) reliably can serve as a complement to task-based fMRI for presurgical mapping of the sensorimotor cortex. MATERIALS AND METHODS: Functional data were obtained in 10 healthy volunteers using a 3 Tesla MRI system. Each subject performed five bilateral finger tapping experiments interleaved with five resting-state experiments. Following p
Exogenous administration of islet amyloid polypeptide (IAPP) has been shown to inhibit both insulin and glucagon secretion. This study examined alpha-cell function in mice with beta-cell specific overexpression of human IAPP (hIAPP) after an oral protein gavage (75 mg whey protein/mouse). Baseline glucagon levels were higher in transgenic mice (41 +/- 4.0 pg/mL, n = 6) than in wildtype animals (19
This study elucidates the nursing of undernourished patients as experienced by eight registered clinical nurses and five nursing assistants by using content analysis. The participants' narratives describe the inner perspective of caring for undernourished patients, known in Sweden as ;the thin ones'. Categories identified were: frustration in nursing, joy in nursing and that undernourishment is ta
AIMS: Adult mammalian cardiomyocytes are traditionally viewed as being permanently withdrawn from the cell cycle. While some groups have reported none, others have reported extensive mitosis in adult myocardium under steady state conditions. Recently, a highly specific assay of (14)C dating in humans has suggested a continuous generation of cardiomyocytes in the adult, albeit at a very low rate. M
