1 The discovery of the supersoft X-ray source RX J0527.8–6954 during the ROSAT first light observation (Trümper et al. 1991) of the Large Magellanic Cloud (LMC) in June 1990 has directed some attention to the optical variable HV 2554 because its location is within the X-ray error circle of RX J0527.8–6954 (Trümper et al. 1991, Greiner et al. 1991). Later ROSAT observations improved the X-ray po...

BACKGROUND AND PURPOSE Hyperintense vessels (HV) detected on fluid-attenuated inversion recovery (FLAIR) in patients with acute ischemic stroke (AIS) indicate cerebral hypoperfusion. However, the clinical meaning of changes in HV is yet to be clarified. Here, we investigated serial changes to HV in patients with AIS who received tissue plasminogen activator (t-PA) therapy. METHODS We studied ...

BACKGROUND Data regarding role of socioeconomic status (SES) as etiology and site of involvement of veins in hepatic venous outflow tract obstruction (HVOTO) is scarce and only described from Nepal. We prospectively evaluated the role of SES in patients with HVOTO. METHODS 70 consecutive patients (41 females; mean age 29, range 3-65 years) with HVOTO were studied. Their clinical history, soci...

In this paper we give a thoughtful exposition of the Clifford algebra Cl(HV ) of multivecfors which is naturally associated with a hyperbolic space HV , whose elements are called vecfors. Geometrical interpretation of vecfors and multivecfors are given. Poincaré automorphism (Hodge dual operator) is introduced and several useful formulas derived. The role of a particular ideal in Cl(HV ) whose ...

BACKGROUND Fluid resuscitation is a core stone of hemorrhagic shock therapy, and crystalloid fluids seem to be associated with lower mortality compared to colloids. However, as redistribution starts within minutes, it has been suggested to replace blood loss with a minimum of a three-fold amount of crystalloids. The hypothesis was that in comparison to high volume (HV), a lower crystalloid volu...

BACKGROUND Hallux valgus (HV) is a common condition involving the progressive subluxation of the first metatarsophalangeal joint due to lateral deviation of the hallux and medial deviation of the first metatarsal. The objective of this study was to evaluate the re-test reliability and validity of self-assessment of HV using a simple clinical screening tool involving four standardised photograph...

The purpose of this study was to compare 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET), hippocampal volumetry (HV), T2 relaxometry, and proton magnetic resonance spectroscopic imaging (1H-MRSI) in the presurgical neuroimaging lateralization of patients with nonlesional, electroencephalogram (EEG)-defined unilateral temporal lobe epilepsy (TLE). Twenty-five patients were...

A portable high-voltage (HV) pulsed generator has been designed for rock fragmentation experiments. The generator can be used also for other technological applications. The installation consists of low voltage block, HV block, coaxial transmission line, fragmentation chamber, and control system block. Low voltage block of the generator, consisting of a primary capacitor bank (300 μF) and a thyr...

OBJECTIVE To identify intracardiac conduction abnormalities in patients with myotonic dystrophy from their clinical, ECG, and genetic features. METHODS 39 consecutive patients (mean (SD) age 42. 9 (12.1) years; 16 female, 23 male) underwent clinical examination, genetic studies, resting and 24 hour ambulatory ECG, signal averaged ECG, and electrophysiological studies. RESULTS 23 patients su...
