The development of immunoreactivity (IR)_in the nervous system of asexually reproducing Microstomum lineare has been studied by a combination of simultaneous and double immunostaining with antisera to 5-HT and RF-amide, as well as with monoclonal antibodies to SCPB (molluscan small cardiactive peptide). Immunoreactivity appears in a distinct sequential(More)
OBJECTIVES To assess the prevalence, clinical characteristics, and treatment options of patients with interstitial lung disease (ILD) in polymyositis and dermatomyositis (PM/DM). PATIENTS AND METHODS Sixty-three consecutive patients with PM/DM underwent standardized screening. Patients with ILD were monitored prospectively, and graded immunosuppression(More)
The purpose of this study was to determine to what extent high-resolution computed tomography (HRCT) of the lungs can distinguish active inflammatory disease from inactive cicatricial disease in patients treated for Wegener's granulomatosis (WG). Twenty-eight WG patients with active pulmonary disease underwent a first HRCT examination immediately before(More)
— An adaptive transversal equalizer based on the least-mean-square (LMS) algorithm, operating in an environment with a temporally correlated interference, can exhibit better steady-state mean-square-error (MSE) performance than the corresponding Wiener filter. This phenomenon is a result of the nonlinear nature of the LMS algorithm and is obscured by(More)
PURPOSE To evaluate the diagnostic accuracy of common magnetic resonance (MR) imaging sequences for detection of small pulmonary nodules by using a chest phantom and porcine lungs containing simulated lesions. MATERIALS AND METHODS Fourteen porcine lungs containing 366 porcine myocardial tissue implants were inflated inside a phantom. Two-dimensional (2D)(More)
PURPOSE To prospectively evaluate the clinical feasibility of magnetic resonance (MR) imaging of the lungs with fast volumetric interpolated three-dimensional (3D) gradient-recalled-echo (GRE) sequences and to compare this examination with standard computed tomography (CT) in patients with lung abnormalities. MATERIALS AND METHODS Twenty-five patients(More)
Prevalence of cervical and thoracic disc protrusions was investigated by MRI in 24 military long-term compressed-air divers and 24 controls. A total of 26 disc protrusions (17 cervical disc protrusions) were detected in 58 % of the divers whereas 18 protrusions were detected in 38 % of the controls (13 disc cervical protrusions). There was no significant(More)
The Gram-positive bacterium Staphylococcus aureus, similar to other pathogens, binds human complement regulators Factor H and Factor H related protein 1 (FHR-1) from human serum. Here we identify the secreted protein Sbi (Staphylococcus aureus binder of IgG) as a ligand that interacts with Factor H by a-to our knowledge-new type of interaction. Factor H(More)
A low probability of intercept (LPI), or low probability of detection (LPD) communication technique known as cyclic code shift keying (CCSK) is described. We discuss the basic concepts of CCSK and describe a system based on the use of random or pseudorandom codes for biphase modulation. We use simulation to show that the bit error rate (BER) for CCSK can be(More)
PURPOSE To use porcine lung explants for reconstructing possible situations in which a vessel wall disruption might have occurred in a patient suffering fatal hemoptysis after pulmonary embolectomy with a hydrodynamic thrombectomy device. METHODS A 76-year-old woman with massive pulmonary embolism underwent transvenous pulmonary embolectomy using a 6-F(More)
