Binding of factor VIIa to tissue factor on human fibroblasts leads to activation of phospholipase C and enhanced PDGF-BB-stimulated chemotaxis

Tissue factor (TF) is the cellular receptor for factor FVIIa (FVIIa), and the complex is the principal initiator of blood coagulation. The effects of FVIIa binding to TF on cell migration and signal transduction of human fibroblasts, which express high amounts of TF, were studied. Fibroblasts incubated with FVIIa migrated toward a concentration gradient of PDGF-BB at approximately 100 times lower

A Randomized Clinical Trial of Prophylaxis in Children with Hemophilia A (the ESPRIT Study).

Background: Prevention of arthropathy is a major goal of hemophilia treatment. While studies in adults have demonstrated an impact of prophylaxis on the incidence of joint bleeds and patients' well-being in terms of improved quality of life (QoL), it is unclear whether or not prophylaxis influences the outcome and well-being perception of children with hemophilia. Objective: This randomized contro

The role of the meniscus in osteoarthritis genesis.

The history of treating meniscal lesions has been characterized by firm belief in "radical" surgery, with serious long-term consequences for the individual and society. The menisci play a critical protective role for the knee joint through shock absorption and load distribution. Currently, the consensus in surgical treatment of meniscal tears is to preserve as much functional meniscal tissue as po

Effect of bioactive polypeptides on leaking large bowel anastomosis and intestines in the rat.

Anastomotic leakage and postoperative adhesions represent major complications after colorectal surgery. We have previously shown a positive effect on both anastomotic strength and abdominal adhesions by the use of differently charged bioactive polypeptides. The present study aimed to investigate the effect of the same polypeptides on the healing of an insufficient intestinal anastomosis, as well a

Disc Hemorrhages and Treatment in the Early Manifest Glaucoma Trial.

PURPOSE: To evaluate the effect of intraocular pressure (IOP)-reducing treatment on the development of disc hemorrhages in patients with glaucoma. DESIGN: Prospective cohort study of patients in the Early Manifest Glaucoma Trial, followed up to 11 years (median = 8 years). PARTICIPANTS: Patients with newly detected glaucoma randomized to argon laser trabeculoplasty plus betaxolol (n = 129) or no i

The accuracy of migration distance measures

The spatial dimension in the definition of internal migration usually refers to the distance someone has tomove to be regarded as a migrant. Lack of precise data on migration distances, however, has obliged migration researchers to use aggregate distance measures whose accuracy is largely unknown, raising potentially serious validity concerns for research. The aim of this paper is to examine the a

Postprandial blood glucose response in relation to gastric emptying and satiety in healthy subjects.

Glucostatic appetite regulation has numerous determinants, among others: cephalic phase digestion, gastric emptying and absorption, together influencing postprandial blood glucose responses and satiety. This short communication presents and reviews studies of gastric emptying, antral distension and postprandial glucose response and their relation to reports of satiety in healthy non-obese over nig

ADP mediates inhibition of insulin secretion by activation of P2Y13 receptors in mice.

AIMS/HYPOTHESES: To investigate the effects of extracellular purines on insulin secretion from mouse pancreatic islets. METHODS: Mouse islets and beta cells were isolated and examined with mRNA real-time quantification, cAMP quantification and insulin and glucagon secretion. ATP release was measured in MIN6c4 cells. Insulin and glucagon secretion were measured in vivo after glucose injection. RESU

Differential Absorption Lidar Mapping of Atmospheric Atomic Mercury In Italian Geothermal Fields

Results from extensive lidar measurements on atmospheric atomic mercury in Italian geothermal fields are reported. A mobile differential absorption lidar system operating on the 254-nm mercury resonance line with a measuring range of about 1 km was used in mineralized as well as nonmineralized areas. Measurements were performed at geothermal power stations and in an unexploited field with natural

Radiative properties of neutral germanium obtained from excited-state lifetime and branching-ratio measurements and comparison with theoretical calculations

Using time-resolved UV laser-induced fluorescence from a laser-produced plasma, natural radiative lifetimes have been measured for 21 levels of Ge I belonging to the odd-parity 4p4d, 4p5d, and 4p6s configurations. Stimulated Brillouin scattering in water has allowed us to compress Nd:YAG laser pulses pumping a dye laser (where YAG denotes yttrium aluminum garnet), thus yielding 1-ns tunable laser

Multicentre phase II trial of capecitabine and oxaliplatin in combination with radiotherapy for unresectable colorectal cancer: The CORGI-L study.

AIMS: This study assessed radiotherapy combined with capecitabine and oxaliplatin in patients with primary, inextirpable colorectal adenocarcinoma. PATIENTS AND METHODS: Forty-nine patients entered the trial. Two cycles of XELOX (capecitabine 1000mg/m(2) bid d1-14+oxaliplatin 130mg/m(2) d1, q3w) were followed by radiotherapy (50.4Gy), combined with capecitabine 825mg/m(2) bid every radiotherapy da

Factors associated with history of non-fatal overdose among opioid users in the Swedish criminal justice system.

BACKGROUND: Overdose (OD) is a common cause of death in opioid users. Also, many current opioid users report a history of non-fatal OD. The present study aimed to identify factors associated with a history of non-fatal OD. METHODS: A sample of 7085 Swedish criminal justice clients with alcohol or drug misuse was assessed, using the Addiction Severity Index. Subjects reporting use of opioids during

Influence of forest cover and herbaceous vegetation on the microbiological and biochemical properties of soil under Mediterranean humid climate

The effects of different Mediterranean vegetation cover on the biological and biochemical quality of soil is not well understood. The aim of this work is to evaluate the effects that different types of vegetation (forestry plots, mainly dominated by Spanish black pine (Pinus nigra Am. ssp salzmannii) and herbaceous plots, where overstorey density is lower and natural herbaceous percentage is highe

The association between changes in synovial fluid levels of ARGS-aggrecan fragments, progression of radiographic osteoarthritis and self-reported outcomes: a cohort study.

OBJECTIVE: To investigate whether change in concentrations over time of aggrecanase generated ARGS-aggrecan in synovial fluid (SF ARGS) associates with progression of radiographic knee Osteoarthritis (OA) and patient-reported outcome in subjects with previous meniscectomy. METHODS: We studied 141 subjects at two time points after meniscectomy. Time point A was on average 18years after meniscecto

High intertester reliability of the Cumulated Ambulation Score for the evaluation of basic mobility in patients with hip fracture.

Objective: To examine the intertester reliability of the three activities of the Cumulated Ambulation Score (CAS) and the total CAS, and to define limits for the smallest change in basic mobility that indicates a real change in patients with hip fracture.Design: An intertester reliability study.Setting: An acute 20-bed orthopaedic hip fracture unit.Subjects: Fifty consecutive patients with a media

MiRNA expression in urothelial carcinomas: Important roles of miR-10a, miR-222, miR-125b, miR-7 and miR-452 for tumor stage and metastasis, and frequent homozygous losses of miR-31.

We analyzed 34 cases of urothelial carcinomas by miRNA, mRNA and genomic profiling. Unsupervised hierarchical clustering using expression information for 300 miRNAs produced 3 major clusters of tumors corresponding to Ta, T1 and T2-T3 tumors, respectively. A subsequent SAM analysis identified 51 miRNAs that discriminated the 3 pathological subtypes. A score based on the expression levels of the 51
