The effects on driving performance of using a hands-free, mobile telephone were investigated in a pursuit-tracking task that simulated driving. Twenty subjects in two age groups, 19-26 years (median = 21 years) and 40-51 years (median 45·5 years), participated, with five males and five females in each group. The primary task was driving safely. The subjects drove for 20 min in each of three second

Pseudomyogenic hemangioendothelioma is a recently described morphologic entity among soft tissue tumors. It is more common in young individuals, shows a male predominance, is often multifocal and involves different tissue planes, and shows a high propensity for local recurrence. To our knowledge, no genetic characteristics of this tumor type have been presented before. Here, we describe the findin

The Aslian language family, located in the Malay Peninsula and southern Thai Isthmus, consists of four distinct branches comprising some 18 languages. These languages predate the now dominant Malay and Thai. The speakers of Aslian languages exhibit some of the highest degree of phylogenetic and societal diversity present in Mainland Southeast Asia today, among them a foraging tradition particularl

A new device for stopping or reducing potentially irritating or harmful emissions from surfaces indoors is described. The device is a surface emissions trap prototype and consists of an adsorbent sheet with a semipermeable barrier surrounded by two thin nonwoven layers. The trap may be applied directly at the source of the emissions e.g. at moisture-affected floors and walls, surfaces contaminated

Background: Low-grade fibromyxoid sarcoma (LGFMS) is an uncommon neoplasm with bland morphology and an indolent clinical course, although metastases may develop in approximately 5-10% of the cases. The diagnosis of LGFMS can be difficult to render from fine needle aspiration cytology (FNAC) alone because of morphological overlap with other spindle cell and myxoid lesions. Objective: To determine c

The aim of this study was to explore participants' experiences and opinions about a free-choice system in relation to policy objectives articulated by the national government and local authorities. A case study was conducted. Thirty five informants participated. Qualitative interviews were undertaken. Results discussed are how to address different dimensions of choice, not only where, also what, b

PURPOSE: To evaluate performances of published gene signatures for the assessment of urothelial carcinoma. EXPERIMENTAL DESIGN: We evaluated 28 published gene signatures designed for diagnostic and prognostic purposes of urothelial cancer. The investigated signatures include eight signatures for stage, five for grade, four for progression, and six for survival. We used two algorithms for classific

We consider high harmonic generation by ultrashort (27-108 fs) laser pulses and calculate the macroscopic response of a collection of atoms to such a short pulse. We show how the harmonic spectrum after propagation through the medium is significantly different from the single-atom spectrum. We use single-atom data calculated by integration of the time-dependent Schrodinger equation and propose a m

Commercial normal stress databases in myocardial perfusion scintigraphy (MPS) commonly consist of 30-40 individuals. The aim of the study was to determine how many subjects are needed.

The aim of this study was to examine whether Multidimensional Pain Inventory (MPI) subscale score changes can be used for monitoring interdisciplinary cognitive behavioural pain rehabilitation programmes, using the Psychological General Well-Being (PGWB) index as an independent variable of rehabilitation outcome. Data from 434 consecutively referred patients disabled by chronic pain were analysed.

Purpose: To investigate patients under the age of 20 with aniridia in Sweden and Norway in order to estimate the prevalence of aniridia, to describe clinical signs and identify complications in the young, which will help improve diagnostic tools and treatment. Methods: A thorough search for patients with aniridia (of all ages) was performed. Sixty-two of the 181 patients were under the age of 20.

OBJECTIVE To study the effects of the phosphodiesterase-5 inhibitor, vardenafil, on contraction and cyclic nucleotide levels in isolated detrusor preparations with and without mucosa, from control rats and rats with partial urethral obstruction (PUO) and intact mucosa. MATERIALS AND METHODS Female Sprague-Dawley rats were divided into groups subjected to PUO for 14 days (six), and sham-operated co

Abstract OBJECTIVES: To identify risk factors for reoperation following surgery for spontaneous pneumothorax. MATERIALS AND METHODS: This is a retrospective clinical study conducted on 240 consecutive patients operated on for spontaneous pneumothorax in Lund University Hospital between January 1996 and December 2003. Patient information was gained from medical charts and operation reports. Logist

The International Congresses have played an important role in the history of genetics. The Eighth International Congress, which in 1948 was held in Sweden, celebrated the conclusion of the war against Nazism and many new decisive scientific advances. It also signaled a hardening of the fight against Lysenkoism, which was growing in strength in the Soviet Union. A rare document is available from th

Postnatal neurogenesis takes place in two brain regions, the hippocampus and the subventricular zone (SVZ). The transcriptional cascade controlling hippocampal neurogenesis has been described in detail; however, the transcriptional control of olfactory bulb neurogenesis is still not well mapped. In this study, we provide insights into the molecular events controlling postnatal olfactory bulb neuro

OBJECTIVES: The objective of this study is to clarify the role of (G4C2)n expansions in the etiology of Parkinson disease (PD) in the worldwide multicenter Genetic Epidemiology of Parkinson's Disease (GEO-PD) cohort. METHODS: C9orf72 (G4C2)n repeats were assessed in a GEO-PD cohort of 7,494 patients diagnosed with PD and 5,886 neurologically healthy control individuals ascertained in Europe, Asia,
