Egypt has one of the world's highest prevalences of hepatitis C virus (HCV) infection, with a majority of genotype 4 infections. To explore the genetic diversity of HCV in Egypt, sera from 131 Egyptians [56 from community studies, 37 chronic hepatitis patients, 28 hepatocellular carcinoma (HCC) patients and 10 patients with non-Hodgkin's lymphoma] were genotyped by restriction fragment-length poly
Platelet activating factor (PAF) has been reported to produce a variety of airway effects including epithelial damage and increased airway-lung absorption of hydrophilic tracers. The present study examines effects of PAF on the guinea-pig tracheobronchial mucosa in vivo. Vehicle with and without PAF (4.0 and 8.0 nmol) was superfused onto the tracheobronchial mucosa. The levels of 125I-albumin, pre
Background. Hepatitis C is frequent problem in dialysis wards. Design. A long time (1989-97) follow up of hepatitis C virus (HCV) infection in a Swedish nephrology unit was performed with anti-HCV screening, confirmatory antibody tests, viral RNA detection and molecular characterization. Case histories were reviewed with focus, onset of infection, liver morbidity and mortality. Results. In October
We have investigated terahertz (THz) emission due to dynamical electron transport in wide miniband GaAs/Al0.3Ga0.7As superlattices. By noting that the time-domain THz emission spectroscopy contains the information on the step response of the electron system to the bias electric field, the obtained THz spectra were compared with the high-frequency conductivities predicted for miniband transport. Ex
OBJECTIVE: To compare the reliability of quantitative measurement of minimum hip joint space with a qualitative global assessment of radiological features for estimating the prevalence of primary osteoarthritis (OA) of the hip in colon radiographs.METHODS: All colon radiographs from patients aged 35 or older, taken at three different radiographic departments in Iceland during the years 1990-96, we
System identification of linear multivariable dy-namic models based on discrete-time data can be performed using a algorithm combining linear regression and LQG-balanced model reduction. The approach is applicable also to unstable system dynamics and it provides balanced models for optimal linear prediction and control.
We have investigated the interactions between cationic poly(amidoamine) (PAMAM) dendrimers of generation 4 (G4), a potential gene transfection vector, with net-anionic model biomembranes composed of different ratios of zwitterionic phosphocholine (PC) and anionic phospho-l-serine (PS) phospholipids. Two types of model membranes were used: solid-supported bilayers, prepared with lipids carrying pal
To determine factors associated with the antipsychotic (AP) prescription for people with dementia (PwD) recently admitted to institutional long-term care facilities (LTCFs) and to ascertain differences in the use of this medication in 8 European countries.
A physically-based, distributed hydrological model (MIKE SHE) was used to quantify overland runoff in response to four extreme rain events and four types of simulated land use measure in a catchment in Norway. The current land use in the catchment comprises arable lands, forest, urban areas and a stream that passes under a motorway at the catchment outlet. This model simulation study demonstrates
Introduction. There are few published guidelines for the management of sexual dysfunctions in men and women, despite the prevalence and lack of attention to these problems. Disorders of sexual function in men include erectile dysfunction, orgasm/ejaculation disorders, priapism, and Peyronie's disease. Aim. To provide evidence-based and expert-opinion consensus guidelines for the clinical managemen
The projection of primary afferents onto spinal interneurons constitutes the first step in sensorimotor transformations performed by spinal reflex systems. Despite extensive studies on spinal somatotopy, uncertainties remain concerning the extent and significance of representational overlap and relation to spinal reflex circuits. To address these issues, the cutaneous projection from the hindpaw a
To study the role of cytotoxin-associated protein (cagA) and vacuolating cytotoxin (vacA) in Helicobacter pylori infection in an experimental murine model, mice were infected with seven strains with different cagA and vacA status. Groups of 10 NMRI mice were challenged and were killed 5 weeks later. In a second study, 20 mice were challenged with a mixture of the same seven strains and killed 1, 3
The transfer of albumin from blood to tissue has been found to be increased in caveolin-1 knock-out (KO) mice. This has been considered to reflect an increased microvascular permeability, conceivably caused by an increased endothelial production of nitric oxide (NO) in mice lacking caveolin-1. To investigate whether such an increase in endothelial NO-production would also affect the glomerular bar
Autoantibodies to insulin (IAA) are one of the first markers of the autoimmune process leading to type 1 diabetes (T1D). While other autoantibodies in T1D have been studied extensively, relatively little is known about IAA and their binding specificities, especially after insulin treatment is initiated. We hypothesize that insulin antibodies (IA) that develop upon initiation of insulin treatment d
Sequential serum samples from four plasma donors (designated A, B, C, and D) at a Chinese blood bank with hepatitis C transmission problems were studied from 1994 to 1997. The samples were examined for antibodies to HCV, for HCV viremia by PCR and HCV genotyping. Co- and superinfections were studied by direct sequencing of the 5'-NCR, core, and HVR-1 regions, using low and high genotype-specific p
Background: More than ever, clinicians need regularly updated reviews given the continuously increasing amount of new information regarding innovative cervical cancer prevention methods. Material and methods: A summary is given from recently published meta-analyses on three possible clinical applications of human papillomavirus (HPV)-DNA testing: triage of women with equivocal or low-grade cytolog
A functionally distinct subset of CD103(+) dendritic cells (DCs) has recently been identified in murine mesenteric lymph nodes (MLN) that induces enhanced FoxP3(+) T cell differentiation, retinoic acid receptor signaling, and gut-homing receptor (CCR9 and alpha 4 beta 7) expression in responding T cells. We show that this function is specific to small intestinal lamina propria (SI-LP) and MLN CD10
Popular Abstract in Swedish Avhandlingen utgörs av en kritisk edition av Johannes Annorelius? latinska brev till brodern Julius (G3, Uppsala universitetsbibliotek). I början av 1700-talet lämnade Johannes Annorelius Uppsala och blev katolik och kapucinmunk i Flandern. Från klostret skrev han många, långa brev på franska och latin till sin lutherske bror i Sverige. I breven förklarar han varför hanThis book presents a critical edition of the Latin letters in ms. G3 (Uppsala University Library) from Johannes Annorelius to his brother. Johannes Annorelius left Sweden as a young student in the beginning of the 18th century and settled down in Flanders, where he converted to the Catholic faith and became a Capuchin friar. In the Capuchin friary Annorelius wrote several extensive letters in Fren
