The trend in cellular chipset design today is to incorporate support for a larger number of frequency bands for each new chipset generation. If the chipset also supports receiver diversity two low noise amplifiers (LNAs) are required for each frequency band. This is however associated with an increase of off-chip components, i.e. matching components for the LNA inputs, as well as complex routing o

Extracts obtained from liquid mycelial fermentations of Chilean species of the Stereum genus showed antifungal activity against Botrytis cinerea. Thirty-six strains were evaluated in vivo and in vitro assays, 25 belonging to Stereum hirsutum (Sh) and 11 to Stereum rameale (Sr). Two types of extracts were obtained: EtOAc-extract (liquid phase) and MeOH-extract (mycelial phase). Plate diffusion assa

A reliable assessment of the optical properties of atmospheric black carbon is of crucial importance for an accurate estimation of radiative forcing. In this study we investigated the spatio-temporal variability of the mass absorption cross-section (MAC) of atmospheric black carbon, defined as light absorption coefficient (σap) divided by elemental carbon mass concentration (mEC). σap and mEC have

Although particulate organic and elemental carbon (OC and EC) are important constituents of the suspended atmospheric particulate matter (PM), measurements of OC and EC are much less common and more uncertain than measurements of e.g. the ionic components of PM. In the framework of atmospheric research infrastructures supported by the European Union, actions have been undertaken to determine and m

BACKGROUND: High-quality non-invasive imaging of the deep venous system in the thorax is challenging, but nevertheless required for diagnosis of vascular pathology as well as for patient selection and preoperative planning for endovascular procedures.PURPOSE: To compare the diagnostic quality of Gadofosveset-enhanced thoracic magnetic resonance venography, seven consecutive patients with suspected

Mesenteric vein thrombosis may induce intestinal ischemia and gangrene. In severe cases, it is necessary to restore venous outflow from the small intestine rapidly. We describe a severe case of mesenteric vein thrombosis that was resolved successfully by mechanical thrombectomy from a transjugular approach followed by selective simultaneous venous and arterial thrombolysis via the superior mesente

PURPOSE: The aim of this study was to describe the prevalence of atherosclerotic plaques based on [(18)F]-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) in a large population characterized by high risk of cardiovascular disease.PROCEDURES: One hundred forty-one patients referred to our department for FDG-PET/CT for suspected lung cancer were re-evaluated for a

OBJECTIVE: It has been shown that [(18)F]-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) can identify macrophage-rich high-risk atherosclerotic plaques in animal models as well as in patients with atherosclerotic plaques in the carotid arteries. The development of inflamed macrophage-rich plaques over time is not well known. This study was performed to determine t

UNLABELLED: Graft infection is a serious complication to vascular surgery. The aim of this study was to assess (18)F-FDG uptake in vascular grafts in patients with or without symptoms of graft infection.METHODS: In all 2,045 patients examined by PET/CT at our clinic, 16 patients with synthetic aortic grafts were identified and reevaluated for (18)F-FDG accumulation. Clinical and biochemical data w

PURPOSE: The aim of this study was to assess the atherosclerotic plaques in a large asymptomatic population stratified based on age and sex.METHODS: [18F]-2-fluoro-2-deoxy-D-glucose (FDG)-PET/CT of 100 men and 100 women, divided in four age groups were examined to assess FDG-accumulating active, calcified inactive and mixed atherosclerotic plaques in eight defined vessel segments.RESULTS: There wa

PURPOSE: To study the survival of adult retinal grafts prepared in a physiologically optimized way.METHODS: Twenty-three rabbits received an adult full-thickness rabbit retinal transplant positioned under the host retina, using a vitrectomy technique. The transplants were prepared using a procedure based on a previously described in vitro model used for physiological experiments on the adult retin

The protein product of the deleted in colorectal cancer (DCC) gene possesses netrin-binding activity and may be involved in axonal guidance during retinal development. The temporal and spatial expression of DCC was analyzed in developing rat retina by means of immunoblotting and immunohistochemistry as well as by reverse transcription-polymerase chain reaction. Transient DCC protein expression is

Acetylcholine is well established as the neurotransmitter of starburst amacrine cells in the vertebrate retina but their function is poorly understood. We compared the distribution of muscarinic m2 receptors in the rat retina with the localization of the starburst cell processes. mAChR2 immunoreactivity appeared in a central band in the inner plexiform layer, which did not co-localize with the pro

Cellulose is insoluble in water but can be dissolved in strong acidic or alkaline conditions. How well dissolved cellulose is in solution and how it organizes are key questions often neglected in literature. The typical low pH required for dissolving cellulose in acidic solvents limits the use of typical characterization techniques. In this respect, Polarization Transfer Solid State NMR (PT ssNMR)

There is a great need to identify new and better prognostic and predictive biomarkers to stratify prostate cancer patients for optimal treatment. The aims of this study were to characterize the expression profile of pre-B cell leukemia homeobox (PBX) transcription factors in prostate cancer with an emphasis on investigating whether PBX3 harbours any prognostic value. The expression profile of PBX3

Recent studies indicate that patients experience pain after day surgery for a longer period than previously known. This requires verification. This was a prospective, descriptive correlational study. A convenience sample of 298 day surgery patients undergoing various surgical procedures was asked to report pain intensity and its interference with daily function 48 hours, seven days and three month

This article discusses the emergence of the episcopal see in Växjö. Contrary to previous research, which has been focused on written sources only, this article also discusses the archaeological record. The result implies that vivid connections between Scania, Denmark and southern Småland can be traced in the Late Iron Age and Early Middle Ages. This is shown by similarities in grave types, runic s

The performance of a dry sampler, with an impregnated denuder in series with a glass fibre filter, using di-n-butylamine (DBA) for airborne isocyanates (200ml min-1) is investigated and compared with an impinger flask with a glass fibre filter in series (1 l min-1). An exposure chamber containing 1,6-hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPDI), and 2,4- and 2,6-toluene diisocy

Sonographers have a high risk of musculoskeletal disorders. This study explores the associations between working conditions and musculoskeletal pain based on the frequency and intensity of pain in the neck and upper extremities. A questionnaire was answered by 291 female sonographers. High prevalence of neck/shoulder pain was associated with eye complaints and headache related to work on the compu

A method is presented for the determination of aromatic amines in aqueous extracts of polyurethane (PUR) foam. The method is based on the extraction of PUR foam using aqueous acetic acid (0.1%, w/v) followed by determination of extracted aromatic amines using hydrophilic interaction liquid chromatography (HILIC) and tandem mass spectrometry (MS/MS) with positive electrospray ionisation. The inject
