Cystatin C, a marker for successful aging and glomerular filtration rate, is not influenced by inflammation.

Abstract Background. The plasma level of cystatin C is a better marker than plasma creatinine for successful aging. It has been assumed that the advantage of cystatin C is not only due to it being a better marker for glomerular filtration rate (GFR) than creatinine, but also because an inflammatory state of a patient induces a raised cystatin C level. However, the observations of an association be

Moisture Transport in Concrete Structures in Swedish Hydro Power Plants

Concrete structures in hydro power plants exposed to harsh environment, such as non-frozen freshwater and long cold winters with freezing temperatures, are always in the danger-zone for suffering from concrete damages. Some existing concrete structures already suffer from different damages caused by high water content. The conditions regarding concrete quality, air entrainment, temperature and tim

Bone bruise, lipohemarthrosis, and joint effusion in CT of non-displaced hip fracture.

BackgroundA suspected occult hip fracture after normal radiography is not uncommon in an elderly person after a fall. Despite a lack of robust validation in the literature, computed tomography (CT) is often used as secondary imaging.PurposeTo assess the frequency and clinical utility of non-cortical skeletal and soft tissue lesions as ancillary fracture signs in CT diagnosis of occult hip fracture

Scattering of a pulsed Rayleigh wave by a spherical cavity in an elastic half space

The time-dependent scattering by a spherical cavity in an elastic half space is considered. The incoming wave is a pulsed Rayleigh wave. The stationary part of the problem is solved by the T-matrix method, and an integration in frequency is performed with a modified gaussian weight function. The displacement components at some points on the surface of the half space are computed and shown in a num

ESTIMATES OF BREAST CANCER GROWTH RATE FROM MAMMOGRAMS AND ITS RELATION TO TUMOUR CHARACTERISTICS.

This study aimed to investigate the growth rate of 31 consecutive invasive breast cancers based on volume measures on at least two serial mammograms and its relation to histopathological findings. The average tumour volume-doubling time in all invasive breast cancer subtypes was 282 d (range 46-749 d). Grade III breast cancers had a significantly shorter average tumour volume-doubling time of 105

Compact fiber-optic fluorosensor employing light-emitting ultraviolet diodes as excitation sources

A compact fluorosensor using three different ultraviolet light-emission diodes as excitation sources for fiber-optic recording of fluorescence 10 spectra from samples is described. A compact integrated spectrometer with linear array wavelength recording is used, yielding a spectral resolution 11 of about 8 nm. In two system implementations ultraviolet light-emitting diodes at 300, 340 and 395 nm,

The effects of foam surface properties on standing body movement.

CONCLUSION: The properties of a foam surface significantly affect body movement variance. Therefore, studies where different kinds of foam have been used may not provide congruent results. OBJECTIVES: To investigate whether different properties of foam affect body movement variance (32 subjects, mean age 22.5 years) in terms of linear head, shoulder, hip and knee movements. Subjects repeated tests

Undermarksanläggningar utmaning för både brandskyddsprojektörer och utrymmande människor

Växande storstäder och ett ökat byggande under mark har gjort att undermarksanläggningar för bland annat transportsystem ökat i antal under de senaste decennierna. Tun- nelsystem för till exempel väg- och järnvägstunnlar har dessutom inte bara ökat i antal, utan också blivit längre och anlagts allt djupare under mark. Detta skapar nya ut- maningar för utrymmande personer och för den projekterande

C-peptide in dried blood spots.

Abstract The aim was to evaluate if the Dried Blood Spot (DBS)-technique can be used to analyse C-peptide. S-C-peptide and paired whole blood clotted on filters, dried, punched out and eluted were sampled from 198 healthy subjects. Six subjects with S-C-peptide values outside the reference range were excluded. A conversion formula using log-DBS-C-peptide was generated in a subset of 156 ( approxim

Antibody-mediated neutralization of cytomegalovirus: modulation of efficacy induced through the IgG constant region.

Antibodies can neutralize the infectious properties of human cytomegalovirus (CMV). In vivo, the major neutralization determinants are located on glycoprotein B (gB). Recombinant human antibodies, that carry different constant regions (IgG1, IgG3 and the synthetic variant IgG3mA) against two of these epitopes were investigated for their ability to recruit the complement cascade for destruction of

Associations between Metabolic Risk Factors and the Hypothalamic Volume in Childhood Leukemia Survivors Treated with Cranial Radiotherapy.

Metabolic complications are prevalent in individuals treated with cranial radiotherapy (CRT) for childhood acute lymphoblastic leukemia (ALL). The hypothalamus is a master regulator of endocrine and metabolic control. The aim of this study was to investigate whether the hypothalamic volume would be associated to metabolic parameters in ALL survivors. Thirty-eight (21 women) survivors participated

Overexpression of UCP2 protects thalamic neurons following global ischemia in the mouse.

Uncoupling protein 2 (UCP2) is upregulated in the brain after sublethal ischemia, and overexpression of UCP2 is neuroprotective in several models of neurodegenerative disease. We investigated if increased levels of UCP2 diminished neuronal damage after global brain ischemia by subjecting mice overexpressing UCP2 (UCP2/3tg) and wild-type littermates (wt) to a 12-min global ischemia. The histopathol

Diluted Operation of a Heavy-Duty Natural-gas Engine

Fuel economy and emissions are the two central parameters in heavy duty engines; most of the existing heavy duty engines are run with diesel. The overall efficiency of diesel engines is good however they suffer from high levels of emissions mainly NOX and soot. Using alternative fuels like Natural-Gas has shown to be a good way to reduce emissions level. Diesel engines can be easily converted to N
