PURPOSE: To measure the apparent diffusion coefficient (ADC) of hyperpolarized (HP) (3)He gas using diffusion weighted MRI in healthy volunteers and patients with emphysema and examine the reproducibility and volume dependency. MATERIALS AND METHODS: A total of eight healthy volunteers and 16 patients with emphysema were examined after inhalation of HP (3)He gas mixed with nitrogen (N(2)) during b

It has long been recognized that arterial inflammation plays a key role in the development of atherosclerosis. More recent evidence has suggested that this inflammation is modulated by autoimmune responses against modified self-antigens, such as oxidized low-density lipoprotein, in the vascular wall. However, the role of the immune system in atherosclerosis appears to be more complex than in class

Fluorescence spectroscopy is one of many optical methods that are potentially clinically useful for noninvasive detection and characterization of disorders on the cervical part of uterus, including precancerous lesions. The cervix uteri exhibits a biologically complex tissue and the morphology of a biopsy is generally not homogenous. The standard histopathological protocol accounts only for the mo

Serial quantitation of BCR-ABL mRNA levels is an important indicator of therapeutic response for patients with chronic myelogenous leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia, but there is substantial variation in the real-time quantitative polymerase chain reaction methodologies used by different testing laboratories. To help improve the comparability of results bet

To evaluate the relationship between the matrix degradation biomarkers, desmosine and isodesmosine (desmosines), and lung function.Plasma and creatinine-corrected urinary total desmosines (P- and U-desmosines), lung function and carbon monoxide diffusion capacity (DL,CO) were measured in a cohort of subjects from the Swedish Twin Registry.Concentrations of U- and P-desmosines were measured in 349

Subcellular localization is an important protein property, which is related to function, interactions and other features. As experimental determination of the localization can be tedious, especially for large numbers of proteins, a number of prediction tools have been developed. We developed the PROlocalizer service that integrates 11 individual methods to predict altogether 12 localizations for a

The Swedish Cancer Registry (founded in 1958) constitutes a unique resource for epidemiological studies of giant cell tumor of bone with potential for use for population-based studies of incidence over time. The aim of this study was to provide what we believe is the first modern population-based assessment of the incidence trends of giant cell tumor, a unique osteoclastogenic lytic stromal tumor

Pediatric lung cancer is uncommon, and small cell lung cancer (SCLC) is exceptionally rare. A 14-year-old previously healthy girl was diagnosed with limited-stage SCLC, which was considered inoperable. She responded well to chemotherapy with carboplatin and etoposide, and surgical resection was performed after 2 cycles. High-dose thoracic radiotherapy in combination with etoposide and carboplatin

BACKGROUND: S100A7 is a calcium-binding protein with chemotactic and antimicrobial properties. S100A7 protein levels are decreased in nasal lavage fluid from individuals with ongoing allergic rhinitis, suggesting a role for S100A7 in allergic airway inflammation. The aims of this study were to describe genetic variation in S100A7 and search for associations between this variation and allergic rhin

Abstract in UndeterminedStrategic recollection refers to control processes that allow the retrieval of information that is relevant for a specific situation. These processes can be studied in memory exclusion tasks, which require the retrieval of particular kinds of episodic information. In the current study, we investigated strategic recollection in reality monitoring by event-related potentials

BACKGROUND: Patients with dental gold restorations are known to have a higher level of gold concentration in blood (B-Au). OBJECTIVES: To further investigate, in a study on patients with intracoronary stents and contact allergy to metals, the gold and nickel release from stainless steel stent with (Au stent) and without (Ni stent) gold plating. METHOD: A total of 460 patients treated with stenting

Hyperbaric oxygen therapy (HBOT) has been suggested to improve healing of hard-to-heal diabetic foot ulcers. Although the wide use of HBOT as a treatment for diabetic foot ulcers has been founded on weak scientific ground, 2 well-designed randomized, double-blind, placebo-controlled studies have in recent years put HBOT on firmer ground as treatment for diabetic patients with chronic foot ulcers.

Negative pressure wound therapy (NPWT) has been adopted as the first-line treatment for poststernotomy mediastinitis as a result of the excellent clinical outcome. The knowledge concerning the effects of NPWT on the cardiovascular system and homeostasis is still limited. The aim of the present study was to investigate whether the plasma levels of neurohormones change during NPWT. Six pigs underwen

Hemophilia patients with inhibitors against FVIII/FIX present with a major challenge in the clinical practice. In the 1970s such patients were treated in association with emergency situations and essential surgery using huge amounts of FVIII/FIX concentrates often preceded by extracorporal adsorption of antibodies against FVIII/FIX. However, moderate to mild bleedings were not effectively treated.

Start-up companies and young firms are driving forces of innovation and regional economic development. They are acknowledged to play a crucial role as innovation agents, particularly, in knowledge-based industries. Most scholars agree that young firms and academic spin-offs innovate more radically, drawing on the knowledge generated in universities and research organisations. It is often assumed t

Mitochondrial disorders recognized in the neonatal period usually present as a metabolic crisis combined with one or several organ manifestations. Liver disorder in association with a respiratory chain deficiency may be overlooked since liver dysfunction is common in severely sick newborn infants. Lactacidosis, hypoglycemia, elevated serum transaminases and conjugated bilirubin are common signs of

Background: Two atopic patients suffering from severe allergy difficult to handle by conventional medication were given Xolair despite an IgE level
