The five highly related envelope subgroups of the avian sarcoma and leukosis viruses (ASLVs), subgroup A [ASLV(A)] to ASLV(E), are thought to have evolved from an ancestral envelope glycoprotein yet utilize different cellular proteins as receptors. Alleles encoding the subgroup A ASLV receptors (Tva), members of the low-density lipoprotein receptor family, and the subgroup B, D, and E ASLV rece...

We implement a novel computational framework for attention that includes recent experimentally derived assumptions on attention which are not covered by standard computational models. To this end, we combine inhomogeneous visual processing, proto-object formation, and parts of TVA (Theory of Visual Attention [2]), a well established computational theory in experimental psychology, which explain...

Mesoporous silica-based materials are currently being explored as a new type of bioscaffold for bone regeneration applications. Zinc(Zn) ion incorporation is shown to play an important role in promoting and also providing antimicrobial activity the scaffold materials. In this work, pore size, geometry, ordered structure on Zn loading release performance two different mesoporous silica, SBA-1 SB...

The primary conjugated linoleic acid (CLA) isomer in milkfat, cis-9, trans-11 CLA, is a proven anticarcinogen in rodents and can be derived directly from ruminal biohydrogenation of linoleic acid. The major fatty acid in pasture, however, is α–linolenic acid; the biohydrogenation of which does not produce cis-9, trans-11 CLA as an intermediate. Therefore, in grazing cows, cis-9, trans-11 CLA mu...

The aim of the present study was to evaluate the role of magnetic resonance imaging (MRI) for the non-invasive detection of coronary abnormalities and specifically the remodeling process in patients with coronary artery disease (CAD). MRI was performed in 10 control healthy subjects and 26 patients with angiographically proven CAD of the right coronary (RCA) or left anterior descending (LAD) ar...

Dissolution of tooth enamel and of hydroxyapatite (HAP) in buffered solutions of ethylenediaminetetraacetic acid (EDTA) has been studied in this laboratory by the physical model approach. To quantitatively explain the experimental results, it was necessary to develop a model incorporating two different types of crystalline sites for dissolution. In a previous study using a one-site diffusion la...

background: the aim of this study is to evaluate the geometry of the distal femur and the proximal tibia in the osteoarthritic knee using 3d reconstructive ct scan imaging. methods: 449 patients with knee osteoarthritis were treated surgically in our center with patient-specific technology total knee arthroplasty. preoperatively, all the patients underwent a ct scan according to a standard prot...

Current behavior is influenced by events in the recent past. In visual attention, this is expressed in many variations of priming effects. Here, we investigate color priming in a brief exposure digit-recognition task. Observers performed a masked odd-one-out singleton recognition task where the target-color either repeated or changed between subsequent trials. Performance was measured by recogn...

The conventional chorioallantoic membrane (CAM) phenotype assay was conducted using 11-day-old embryonatic eggs of white Leghorn strains, each inoculated with 0.2 ml of subgroup A Rous sarcoma virus (RSV) and subgroup C RSV separately containing 10(3)pfu ml(-1). Eggs were further incubated for hatching. Harvesting of CAMs for counting of pocks and monitoring chicks for liver tumour (LT) mortali...
