Minimizing Contrast Medium Doses to Diagnose Pulmonary Embolism with 80-kVp Multidetector Computed Tomography in Azotemic Patients.

Background: In diagnosing acute pulmonary embolism (PE) in azotemic patients, scintigraphy and magnetic resonance imaging are frequently inconclusive or not available in many hospitals. Computed tomography is readily available, but relatively high doses (30-50 g I) of potentially nephrotoxic iodine contrast media (CM) are used. Purpose: To report on the diagnostic quality and possible contrast-ind

Spontaneous movements: Effect of denervation and relation to the adaptation of nociceptive withdrawal reflexes in the rat.

Spontaneous movements are a ubiquitous phenomenon during development. Recently, we demonstrated that these movements play a key role in the functional adaptation of spinal reflex circuits. Here, we analyse the role of afferent input in the generation of spontaneous movements and characterize the occurrence of different types of spontaneous movements and their relation to the functional adaptation

Expression of GADS enhances FLT3-induced mitogenic signaling.

GADS is a member of a family of SH2 and SH3 domain-containing adaptors that functions in tyrosine kinase-mediated signaling cascades. Its expression is largely restricted to hematopoietic tissues and cell lines. Therefore, GADS is mainly involved in leukocyte-specific protein tyrosine kinase signaling. GADS is known to interact with tyrosine-phosphorylated SHC, BCR-ABL and KIT. The SH2 domain of G

Empirical Estimates of the Lead Time Distribution for Prostate Cancer Based on Two Independent Representative Cohorts of Men Not Subject to Prostate-Specific Antigen Screening.

BACKGROUND: Lead time, the estimated time by which screening advances the date of diagnosis, is used to calculate the risk of overdiagnosis. We sought to describe empirically the distribution of lead times between an elevated prostate-specific antigen (PSA) and subsequent prostate cancer diagnosis. METHODS: We linked the Swedish cancer registry to two independent cohorts: 60-year-olds sampled in 1

Growth dynamics of tree-line and lake-shore Scots pine (Pinus sylvestris L.) in the central Scandinavian Mountains during the Medieval Climate Anomaly and the early Little Ice Age

Trees growing at their altitudinal or latitudinal distribution in Fennoscandia have been widelyused to reconstruct warm season temperatures, and the region hosts some of the world’slongest tree-ring chronologies. These multi-millennial long chronologies have mainly beenbuilt from tree remains found in lakes (subfossil wood from lake-shore trees). We used aunique dataset of Scots pine tree-ring dat
