Aerospace applications and energy-saving strategies in general raised the interest and study in the field of lightweight materials, especially on aluminum alloys. Aluminum alloy itself does not have appropriate wear resistance. Therefore, improvement of surface properties is required in practical applications, especially when aluminum is in contact with other parts. In this work, first titanium...

OBJECTIVES To determine the pathogenic association of latent Epstein-Barr virus (EBV) infections with both typical hydroa vacciniforme (HV) and severe HV-like eruptions, and to survey the complications and outcomes of patients. DESIGN Case series. PATIENTS Twenty-nine patients with HV or severe HV-like eruptions. INTERVENTIONS In situ hybridization and immunostaining of biopsy specimens; ...

OBJECTIVE To test, with a sample of adolescent mothers (16-20 at childbirth) and their first-born infants/toddlers (average age 1 year), whether the impact of a home visiting (HV) child maltreatment prevention program was moderated by maternal depression. METHODS The study design was a randomized controlled trial of Healthy Families Massachusetts, a statewide child maltreatment prevention pro...

BACKGROUND/AIMS Hyperdynamic circulation, which is characterized by increased cardiac output (CO), normal or low arterial blood pressure (BP), and decreased systemic vascular resistance (SVR), occurs in patients with liver cirrhosis (LC). However, differences of hemodynamics between patients with alcoholic LC (ALC) and viral LC are not well understood. The aim of the present study was to compar...

BACKGROUND AND PURPOSE The causal effect of early febrile convulsions (FC) on later-onset temporal lobe epilepsy (TLE) remains unclear. In this study, we sought to examine the hippocampal alterations in epileptic children with or without FC history by using MR spectroscopy and volumetry. METHODS Fifty-five children ranging in age from 18 months to 15 years were enrolled in this study. Subject...

BACKGROUND/AIM Among various kidney disease models, there are few rat glomerulonephritis (GN) models that develop in a short time, and with mainly glomerular lesions. Hypoxia-inducible factor (HIF)-1alpha is a transcriptional factor that induces genes supporting cell survival, but the involvement of HIF-1alpha in attenuating the progression of GN remains to be elucidated. We developed a new mod...

BACKGROUND Abnormality of hepatic vein (HV) waveforms evaluated by Doppler ultrasonography has been widely studied in patients with chronic liver disease. We investigated the correlation between changes in HV waveforms and portal vein velocity (PVVel), the hepatic artery pulsatility index (HAPI), and also the extent of abnormal Doppler HV waveforms expressed as damping index (DI), severity of p...

in this paper, some fundamental concepts are given relating to fuzzytopological spaces. then it is shown that there is a contravariant functorfrom the category of the pointed fuzzy topological spaces to the category ofgroups and homomorphisms. also the fuzzy topological spaces which are hopfspaces are investigated and it is shown that a pointed fuzzy toplogicalspace having the same homotopy typ...
