In the course of a few months in 1997, about 20 per cent of Stockholm Stock Exchange's primary-list firms transferred to the Exchange's secondary list due to a new tax policy. Drawing on a theory of social influence, we suggest that the transfer decisions depended both on the firms' social embeddedness with other firms in the population at risk and their economic predisposition to make such transf

An electrically small frequency-reconfigurable antenna with a very wide tuning band is proposed. Three varactor diodes are used to achieve the tunable capacitance. With a modifled feeding structure, the measured tuning range of the fabricated antenna reaches from 457.5 to 894.5 MHz, and the tuning band enhancement is also explained through an equivalent circuit analysis.

BACKGROUND: Deep venous thrombosis (DVT) is much less common in the upper than in the lower extremity. Furthermore, there is limited information on risk factors for and the prognosis of upper extremity (UE)DVT in the general population. AIMS: To estimate incidence, risk factors, and prognosis in UEDVT. MATERIAL AND METHODS: Among a total of 1203 patients with venous thromboembolism (VTE) diagnosed

PURPOSE To improve the poor prognosis of patients with primary disseminated multifocal Ewing sarcomas (PDMES) with a dose-intense treatment concept. PATIENTS AND METHODS From 1999 to 2005, 281 patients with PDMES were enrolled onto the Euro-EWING 99 R3 study. Median age was 16.2 years (range, 0.4 to 49 years). Recommended treatment consisted of six cycles of vincristine, ifosfamide, doxorubicin, a

The purpose of the study was to compare changes in oral health during intubation until 48 hours after extubation in neuroscience intensive care unit (ICU) patients enrolled in a standard or a comprehensive oral care protocol. The effects of manual toothbrushing (standard group, n = 31) were compared with those of tongue scraping, electric toothbrushing, and moisturizing (comprehensive group, n = 2

BACKGROUND: Former investigations have demonstrated that patch test preparations containing Disperse Blue (DB) 106 and DB 124 are impure. OBJECTIVE: To investigate the significance of impurities in preparations of disperse dyes with regard to contact allergy. MATERIALS/METHODS: 21 patients allergic to DB 106 and/or DB 124 were tested with dilution series of commercial and purified DB 106 and DB 12

Objective: To investigate the development of hand involvement and activities of daily life (ADL) in early systemic sclerosis (SSc), and to examine the usefulness of the Hand Mobility in Scleroderma (HAMIS) test in a longitudinal study. Methods: Forty-three patients with disease duration no longer than 3 years and at least 4 years of follow-up formed the study group. Based on skin involvement, 31 p

It is debated whether young athletes need to specialize early, or if it is more beneficial to follow the path of early diversification. The present study investigates the career paths and related motivational and volitional factors of Danish elite and near-elite team sport athletes. Seventy-six athletes matched by sport, age and sex participated in the study. Elite athletes started their career la

It is unknown how the return to supine position influences duration of loss of consciousness (LOC) and cardioinhibition during tilt test.

OBJECTIVE: Elevated leukocyte count is a classic marker of systemic inflammation. This study examined whether the leukocyte count is associated with incidence of coronary events (CE) and stroke during a long follow-up period. METHODS: A total of 17,131 men and 2932 women, aged 27-61 years, without history of cardiovascular disease (CVD), were enrolled. Incidence of CE and stroke was studied in rel

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) carries a dismal prognosis. There is a need to identify prognostic subtypes of PDAC to predict clinical and therapeutic outcomes accurately, and define novel therapeutic targets. The purpose of this review was to provide a systematic summary and review of available data on immunohistochemical (IHC) prognostic and predictive markers in patients w

To evaluate if dietary vitamin D intake is adequate for sufficient vitamin D status during early winter in children living in Sweden, irrespective of latitude or skin color.

BACKGROUND:: Excessive loss of functional liver mass results in hepatic dysfunction and is associated with an increased sensitivity to infection. This experimental study investigated the role of Rho-kinase in hepatectomy-induced sensitization to endotoxin. METHODS:: Male C57BL/6J mice underwent 68 per cent hepatectomy and were injected 24 h later with 100 microg Escherichia coli lipopolysaccharide

ABSTRACT Introduction. Sexual coercion is recognized as a serious societal problem. Correlates and risk factors of sexually abusive behavior in females are not well known. Aim. Etiological theory and empirical study of female perpetrators of sexual coercion are usually based on small or highly selected samples. Specifically, population-based data are needed to elucidate risk/protective factors. Ma

In an earlier study, infection of human pancreatic islets with epidemic strains of echovirus (E4, E16, E30), with proven but differently ability to induce islet autoimmunity, resulted either in a severe damage (i.e. E16 and E30) or proceeded without visible changes in infected islets (i.e. E4). In this study, the ability of these strains to replicate in beta cells and the consequence of such an in
