Atherosclerosis is initiated by the retention of lipoproteins on proteoglycans in the arterial intima. However, the mechanisms leading to proteoglycan accumulation and lipoprotein retention are poorly understood. In this study, we set out to investigate the role of ADAMTS-5 (a disintegrin and metalloprotease with thrombospondin motifs-5) in the vasculature. ADAMTS-5 was markedly reduced in athe...

A monoclonal antibody to human antihemophilic factor (AHF, factor VIII) was derived from BALB/c mouse spleen cells fused with P3x63Ag8 mouse plasmacytoma cells. This antibody, harvested from culture medium or ascites fluid, reacted with purified AHF and with plasmas with normal subjects or classic hemophiliacs, as measured by enzyme-linked immunosorbent assay (ELISA), but not with plasmas from ...

In this investigation the denture retention was measured and the influence of denture -retention on ima'sticatory efficiency was examined. The investigation was iperf armed on 36 comiplete denture wearers. The test of masticatory efficiency wals used according to Ni'kšić (1965). The meaisuriinig of denture retention was made by specially constructed mechanical scale, which wa's designed so that...

We examined memory for pictures and words in middle-age (45-59 years), young-old (60-74 years), old-old (75-89 years), and the oldest-old adults (90-97 years) in the Louisiana Healthy Aging Study. Stimulus items were presented and retention was tested in a blocked order where half of the participants studied 16 simple line drawings and the other half studied matching words during acquisition. F...

The E1B 55-kDa and E4 34-kDa oncoproteins of adenovirus type 5 (abbreviated here as E1B-55kD and E4-34kD) promote the export of viral mRNA and inhibit the export of most cellular mRNA species. We show that the intracellular complex containing E1B-55kD and E4-34kD continuously shuttles between the nucleus and the cytoplasm, and may thus serve as a nucleocytoplasmic transporter for viral mRNA. We...

The sequence Ser-Glu-Lys-Asp-Glu-Leu (SEKDEL) has been shown to be a signal which leads to retention of at least two proteins in the endoplasmic reticulum of animal cells (Munro and Pelham, 1987). In this study we tested the function of this signal by appending it to two secretory proteins, rat growth hormone and the alpha subunit of human chorionic gonadotrophin (hCG-alpha). We used oligonucle...

We evaluated the effects of infusions of the NMDA receptor antagonist D,L-2-amino-5-phosphonopentanoic acid (AP5) into the basolateral nucleus of the amygdala (BLA) on the formation and expression of memory for inhibitory avoidance. Adult male Wistar rats (215-300 g) were implanted under thionembutal anesthesia (30 mg/kg, ip) with 9.0-mm guide cannulae aimed 1.0 mm above the BLA. Bilateral infu...

The role of the pineal gland and its hormone-melatonin-as to the impact of vasopressin (VP) and/or oxytocin (OT) on the regulation of behavior was studied, the passive avoidance task being chosen as an experimental model. The results showed that VP facilitated the avoidance latency during the first retention trial; after pinealectomy, however, VP was ineffective in this regard. Intraperitoneal ...

Two experiments using a state-dependent retention (SDR) design determined whether MK-801 blocked the acquisition and retention of an avoidance response. In Experiments 1 and 2, rats were trained and tested 30 min after injections of either saline or MK-801 (0.05 and 0.10 mg/kg, respectively). Two minutes after training, subjects were immediately tested, and in both experiments, the avoidance re...

The main purpose of this study is to evaluate the effect of staffs' customer orientation on customer satisfaction, commitment and retention. For this aim, the model of customer orientation of service staff, offered by Thurau was combined with customer orientation model of Donavan and Hoctt and a new model was devised for Mellat Banks of North West of Iran. The trend of this research is applied,...
