A time domain method for scattering from a one-dimensional homogeneous viscoelastic slab with impedance mismatched interfaces is presented. A viscoelastic medium is characterised by a time-dependent memory function. The reconstruction of this memory function from scattering data is an important and interesting inverse problem. Special attention is paid to the transmitted field. It is shown that tr
The transcription factor, X-box Binding Protein-One (XBP1), controls the development and maintenance of the endoplasmic reticulum (ER) in multiple secretory cell lineages. We show here that Hepatocyte Nuclear Factor 4-alpha (HNF4α) directly induces XBP1 expression. Mutations in HNF4α cause Mature-Onset Diabetes of the Young I (MODYI), a subset of diabetes characterized by diminished GSIS. In mouse
The glycosaminoglycan hyaluronic acid (HA) is an important component of the extracellular matrix (ECM) in the brain. CD44 is a cell adhesion molecule that binds to HA in the ECM and is present on astrocytes, microglia and certain neurons. Cell adhesion molecules have been reported to be involved in anxiety and mood disorders. CD44 levels are decreased in the cerebrospinal fluid (CSF) of depressed
Cell penetrating peptides (CPPs) are currently used to deliver various macromolecular cargos to intracellular sites of action both in vitro and in vivo on an experimental basis. During the last few years, even more evidence has accumulated indicating that the main route of entry for most CPPs is through endocytosis rather than direct membrane penetration, as initially proposed. The specific endocy
Treatment of Mv1Lu mink lung epithelial cells with transforming growth factor-beta 1 (TGF-beta 1) prevents phosphorylation of the retinoblastoma susceptibility gene product, RB, in late G1 phase of the cell cycle, which is thought to retain RB in a growth-suppressive state. This effect is paralleled by cell cycle arrest in late G1 (M. Laiho, J. A. DeCapric, J. W. Ludlow, D. M. Livingston, and J. M
To test the reproducibility of Sonoclot coagulation analysis (SCA; Sienco Inc, Morrison, CO). The authors wished to determine if the mix/release of the preloaded celite activator in standard Sono-cuvettes could be responsible for the high variation coefficients for SCA parameters with citrated whole blood and if citrated whole blood is optimal for SCA.
The purpose of preventive home visits is to promote overall health and wellbeing in old age. The aim of this paper was to describe the process of the development of evidence-based preventive home visits, targeting independent community-living older persons. The evidence base was generated from published studies and practical experiences. The results demonstrate that preventive home visits should b
BACKGROUND: Thrombin activation measured by the levels of the complex between activated protein C (APC) and the protein C inhibitor (PCI) is elevated in several atherosclerotic disorders. The aim of this study was to evaluate whether levels of the APC-PCI complex are related to the prognosis in peripheral arterial disease (PAD). Longitudinal study performed at the Vascular Centre, Malmö University
Rationale, aims and objectives The aim of this study was to compare acute hospital utilization and costs for patients with refractory angina pectoris undergoing spinal cord stimulation (SCS) versus enhanced external counterpulsation (EECP). Method Seventy-three persons were included in this register study. The acute hospital utilization and costs for SCS and EECP were followed over a period from 1
Because of the inexact nature of visual classification schemes and the resulting uncertainties of specifying raw material origins, geochemical methods applicable for sourcing Scandinavian flint have been sought. The authors have shown that EDXRF analysis yields geochemical data sufficiently precise and accurate to discriminate among many different varieties of archaeologically significant flint. H
Study Type - Diagnostic (exploratory cohort) Level of Evidence 2b OBJECTIVES: To assess variation of total prostate-specific antigen (tPSA), free PSA (fPSA), percent fPSA, human glandular kallikrein 2 (hK2) and intact PSA measured three times within 2 weeks. Knowledge of the variation in an individual's PSA level is important for clinical decision-making. PATIENTS AND METHODS: Study participants w
Background: Tumour hypoxia is a common characteristic of many solid human tumours, and is associated with a poor prognosis in various types of cancer. Metabolic changes occur when cells are exposed to low oxygen pressure; however, little is known about the mechanisms underlying malignant transformation and/or progression caused by hypoxia. Materials and Methods: We monitored global gene expression
Individuals diagnosed with schizophrenia show deficiencies of basic neurophysiological sorting mechanisms. This study further investigated this issue, focusing on the two phenomena laterality of coding and auditory forward masking. A specific audiometric method for use in psychiatry was the measuring set up to register brain stem audiograms (ABRs). A sample of 49 schizophrenic patients was compare
This paper introduces a new replenishment policy for inventory control in a two-level distribution system consisting of one central warehouse and an arbitrary number of nonidentical retailers. The new policy is designed to control the replenishment process at the central warehouse, using centralized information regarding the inventory positions and demand processes of all installations in the syst
OBJECTIVES: Testicular germ-cell cancer (TGCC) patients are at risk of developing hypogonadism but no risk factors have yet been defined. METHODS: Blood was collected from 143 TGCC patients (after orchidectomy, prior to further therapy (T0) and 6, 12, 24, 36 and 60 months (T6, T12, T24, T36 and T60) after therapy). Biological hypogonadism (BH) was defined as: serum testosterone below 10 nmol/l and
