Risk factors and treatment at recurrent stroke onset: Results from the recurrent stroke quality and epidemiology (RESQUE) study

Background: Much effort has been made to study first-ever stroke patients. However, recurrent stroke has not been investigated as extensively. It is unclear which risk factors dominate, and whether adequate secondary prevention has been provided to patients who suffer from recurrent stroke. Also, the different types of recurrent stroke need further evaluation. Methods: The study included patients

Haemophilia B carrier detection by factor IX:C analysis; no impact of the type of mutation or severity of disorder

Haemophilia B, an X-linked recessive bleeding disorder characterized by lack or deficiency of factor IX, has been shown to be caused by any of a variety of DNA abnormalities (partial or total deletions, nonsense or missense mutations). Since in most countries carrier detection is based on factor IX coagulant activity (FIX:C) assay, this study was designed to determine whether carriers' FIX:C value

Hollow fibre-supported liquid membrane extraction and LC-MS/MS detection for the analysis of heterocyclic amines in urine samples

Heterocyclic amines (HCAs) are potent mutagens/carcinogens to which humans are frequently exposed through the consumption of cooked meat and fish food. The effect of normal intake of HCAs and their role in the aetiology of human cancer is unknown. To some extent, limitations of the existing analytical methods in monitoring the low levels of HCAs in biological samples have hindered obtaining conclu

Activated Protein C Protein C Inhibitor Complex in Patients With Abdominal Aortic Aneurysms: Is It Associated With Diameter and Growth Rate?

Increased thrombin activation has been documented in patients with abdominal aortic aneurysm (AAA). APC-PCI complex, a new biological marker of thrombin generation, was measured in a population of 232 patients with AAA relative and a control group and the association between aneurysm size, growth rate and APC-PCI was studied. The patients were divided into cohorts according to the AAA diameter and

Effects of intrapleural mitoxantrone and mepacrine on malignant pleural effusion--a randomised study

30 patients with malignant pleuritis were randomised to be treated, either with intrapleural instillation of mepacrine chloride or with mitoxantrone. The patients were evaluated with chest X-ray and a symptom questionnaire during a follow-up period of 12 weeks. Mitoxantrone levels in the pleural space and plasma were measured at different time points in some of the patients. High concentrations of

Psychometric properties of a Swedish version of the Kansas City Cardiomyopathy Questionnaire in a Chronic Heart Failure population.

BACKGROUND: Valid assessments of health-related Quality of Life (HRQL) are increasingly important in chronic, incurable conditions, such as chronic heart failure (CHF). AIMS: To evaluate the psychometric properties of a Swedish version of the Kansas City Cardiomyopathy Questionnaire (KCCQ) in hospitalized patients with decompensated CHF. METHOD AND RESULTS: The KCCQ and SF-36 were administered to

Highly efficient and versatile anodes for biofuel cells based on cellobiose dehydrogenase from Myriococcum thermophilum

A powerful alternative to glucose oxidase as anode material in implantable biofuel cells is presented: Cellobiose dehydrogenase (CDH) from the ascomycete Myriococcum thermophilum (MtCDH) catalyzes the electrochemical oxidation of glucose, lactose, and cellobiose over a broad pH range. Current densities of more than 1 mA . cm(-2) can be reached when MtCDH is wired to an Os redox polymer in the pres

Particle Emission from High-spin States

The present status of prompt particle emission from high-spin states in the mass A~60 region is shortly summarized. The focus lies on recent results from a GAMMASPHERE experiment, which aimed at the combined in-beam high-resolution spectroscopy of light charged particles and γ rays. More detailed studies of known cases as well as the identification of new cases of discrete prompt proton and α-part

Experimental verification of degrees of freedom for co-located antennas in wireless channels

It has been postulated that six co-located orthogonally polarized electrical and magnetic dipoles can offer up to six degrees of freedom (DOFs) in a multipath scattering environment. In other words, a six-fold increase in channel capacity can be achieved in the context of MIMO systems. However, due to the complexity in designing and measuring such a six-port antenna, to our knowledge, no experimen

Tunneling spectroscopy of superconducting nanospheres

Energy spectra of superconducting nanospheres observed via tunneling spectroscopy are theoretically discussed. In the energy gap we find small peaks which correspond to the two-particle dynamics beyond the mean-field BCS approximation. These peaks promise to be a sensitive test of theories of superconductivity as their number and positions depend on the approximation used.

Myosin 5a controls insulin granule recruitment during late-phase secretion.

We have examined the importance of the actin-based molecular motor myosin 5a for insulin granule transport and insulin secretion. Expression of myosin 5a was downregulated in clonal INS-1E cells using RNAinterference. Stimulated hormone secretion was reduced by 46% and single-cell exocytosis, measured by capacitance recordings, was inhibited by 42% after silencing. Silencing of Slac-2c/MYRIP, whic

Adaptive spectral Doppler estimation

In this paper, 2 adaptive spectral estimation techniques are analyzed for spectral Doppler ultrasound. The purpose is to minimize the observation window needed to estimate the spectrogram to provide a better temporal resolution and gain more flexibility when designing the data acquisition sequence. The methods can also provide better quality of the estimated power spectral density (PSD) of the blo

Additive and non-additive genetic architecture of two different-sized populations of Scabiosa canescens

Future adaptation to changes in the environment depends on the existence of additive genetic variances within populations. Recently, considerable attention has also been given to the non-additive component, which plays an important role in inbreeding depression and bottleneck situations. In this study, I used data from a North Carolina II crossing experiment, analysed with restricted maximum-likel

Self-reported symptoms among women after cosmetic breast implant and breast reduction surgery

A retrospective cohort study was performed in Sweden to evaluate the possibility that an individual symptom or constellation of illness symptoms related to silicone occurs in women after breast implant surgery. A random sample (n = 2500) of all women in the Swedish national implant registry who underwent breast augmentation surgery with alloplastic breast implants during the years 1965 through 199

Early Miocene pollen and spores from western Jylland, Denmark - environmental and climatic implications

A palynological analysis of a Lower Miocene cored section from Sonder Vium in western Jylland, Denmark, provides new data regarding the vegetation and climate during the earliest Neogene. Most samples yielded well-preserved palynomorphs. Terrestrial pollen and spores dominate, with lesser proportions of dinoflagellates. A fluvial input into the marine setting is corroborated by the presence of fre

Appropriate assessment of neighborhood effects on individual health: Integrating random and fixed effects in multilevel logistic regression

The logistic regression model is frequently used in epidemiologic studies, yielding odds ratio or relative risk interpretations. Inspired by the theory of linear normal models, the logistic regression model has been extended to allow for correlated responses by introducing random effects. However, the model does not inherit the interpretational features of the normal model. In this paper, the auth
